Abstract
This study aimed to evaluate the antibacterial activity of nine boron derivatives against biofilm-forming pathogenic bacteria. The effect of boron derivatives (CMB, calcium metaborate; SMTB, sodium metaborate tetrahydrate; ZB, zinc borate; STFB, sodium tetra fluorine borate; STB, sodium tetraborate; PTFB, potassium tetra fluor borate; APTB, ammonium pentabo-rate tetrahydrate; SPM, sodium perborate monohydrate; Borax, ATFB, ammonium tetra fluorine borate) on bacteria isolated from blood culture was determined by the minimum inhibitory concentration (MIC) method. Then, biofilm formation potentials on microplates, tubes, and Congo red agar were examined. The cytotoxicity of boron derivatives was determined by using WST-1-based methods. The interaction between the biofilm-forming bacteria, fibroblast cells, and boron derivatives was determined with the infection model. We found that the sodium metaborate tetrahydrate molecule was effective against all pathogens. According to the optical density values detected at 630 nm in microplates, meticillin-resistant Staphylococcus aureus was observed to have the most substantial biofilm ability at 0.257 nm. As a result of cytotoxicity studies, it has been determined that a 1 µg/L concentration of boron derivatives is not toxic to fibroblast L929 cells. In cell culture experiments, these boron derivatives have very serious inhibitory activity against biofilm-forming pathogens in a short treatment period, such as 2-4 h. Furthermore, using these molecules on inanimate surfaces affected by biofilms would be appropriate instead of living cells.

Abstract
OBJECTIVE The antimicrobial effects of a borate-based bioactive glass matrix (BBBGM) on clinically relevant microorganisms was investigated for up to seven days in vitro. METHOD A total of 19 wound-relevant pathogens were studied using the in vitro AATCC 100 test method. RESULTS The reduction of viable Gram-negative and Gram-positive bacteria and yeasts at days 4 and 7 post-culture on the BBBGM was significant (> 4log10) in most cases. Mould counts were reduced (<2log10) during the seven-day assessment, indicating that mould viability and reproduction was inhibited. The cell count of each organism was reduced at seven days indicating that the BBBGM not only reduced the viable cell count, but that the cell count did not recover during the seven-day period, indicating a sustained reduction in pathogenic activity. CONCLUSION Based on the present results, the use of a BBBGM as a pathogenic barrier should be considered as a tool for combating pathogenic colonisation and infection in acute and hard-to-heal (chronic) wounds.

Abstract
Borate bioactive glasses have gained attention in recent years due to their therapeutic and regenerative effects in vivo. However, borate bioactive glasses release alkaline ions, increasing the local pH and creating a toxic environment for cell culture studies. A partial compositional substitution of phosphate for borate can create a pH-neutral glass that does not significantly affect the local pH while still releasing therapeutic ions. In the present study, a series of Na-Ca-borophosphate bioactive glasses with different borate-to-phosphate ratios was evaluated in vitro and in vivo for cytotoxicity and angiogenic effects. Compared to more basic borate glasses, the pH-neutral glasses supported endothelial cell migration and stimulated greater blood vessel formation in a chick chorioallantoic membrane model. The results from this study indicate that these pH-neutral glasses are promising angiogenic biomaterials for use in tissue engineering and regenerative medicine.

Abstract
Polymeric hydrogel materials with multiple functions are in great demand in practical biomedical scenarios. In this work, a self-healing hydrogel with both antimicrobial properties was prepared using a strategy that combines dynamic imine and borate ester bonds. In this hydrogel, polyvinyl alcohol (PVA) is used as the base network, and borax solution as the cross-linking agent, and borate ester bonds can be formed between these two. Dialdehyde carboxymethyl cellulose (DCMC) was selected to cross-link with the amino groups in carboxymethyl chitosan (CMCS) and polyethyleneimine (PEI) to form dynamic imine bonds. The PVA/PEI/DCMC/CMCS hydrogels prepared by double chemical cross-linking have good mechanical properties (maximum tensile strength up to 289 KPa and strain at the break up to 1025%). Due to the uniqueness of the two chemical bonds, the hydrogel material is self-healing at room temperature without additional stimulation. In addition, the inherent antibacterial properties of the raw materials in this hydrogel confer antibacterial properties, with a kill rate of up to 99% against E. coli and S. aureus. The multifunctional hydrogels developed in this study provide more ideas and references for the future application of hydrogel materials in practical scenarios.

Abstract
In this study, zinc (Zn)- and copper (Cu)-doped 13-93B3 borate mesoporous bioactive glasses (MBGs) were successfully synthesized using nitrate precursors in the presence of Pluronic P123. We benefited from computational approaches for predicting and confirming the experimental findings. The changes in the dynamic surface tension (SFT) of simulated body fluid (SBF) were investigated using the Du Noüy ring method to shed light on the mineralization process of hydroxyapatite (HAp) on the glass surface. The obtained MBGs were in a glassy state before incubation in SBF. The formation of an apatite-like layer on the SBF-incubated borate glasses was investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The incorporation of Zn and Cu into the basic composition of 13-93B3 glass led to changes in the glass transition temperature (Tg) (773 to 556 °C), particle size (373 to 64 nm), zeta potential (−12 to −26 mV), and specific surface area (SBET) (54 to 123 m2/g). Based on the K-means algorithm and chi-square automatic interaction detection (CHAID) tree, we found that the SFT of SBF is an important factor for the prediction and confirmation of the HAp mineralization process on the glasses. Furthermore, we proposed a simple calculation, based on SFT variation, to quantify the bioactivity of MBGs. The doped and dopant-free borate MBGs could enhance the proliferation of mouse fibroblast L929 cells at a concentration of 0.5 mg/mL. These glasses also induced very low hemolysis (<5%), confirming good compatibility with red blood cells. The results of the antibacterial test revealed that all the samples could significantly decrease the viability of Pseudomonas aeruginosa. In summary, we showed that Cu-/Zn-doped borate MBGs can be fabricated using a cost-effective method and also show promise for wound healing/skin tissue engineering applications, as especially supported by the cell test with fibroblasts, good compatibility with blood, and antibacterial properties.

Abstract
A simple process based on the dual roles of both magnesium oxide (MgO) and iron oxide (FeO) with boron (B) as precursors and catalysts has been developed for the synthesis of borate composites of magnesium and iron (Mg2B2O5-Fe3BO6) at 1200°C. The as-synthesized composites can be a single material with the improved and collective properties of both iron borates (Fe3BO6) and magnesium borates (Mg2B2O5). At higher temperatures, the synthesized Mg2B2O5-Fe3BO6 composite is found thermally more stable than the single borates of both magnesium and iron. Similarly, the synthesized composites are found to prevent the growth of both gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli) pathogenic bacteria on all the tested concentrations. Moreover, the inhibitory effect of the synthesized composite increases with an increase in concentration and is more pronounced against S. aureus as compared to E. coli.

Abstract
BACKGROUND Boron (B) is an element involved in many physiological processes in humans and accelerates wound healing and increases angiogenesis. This study aimed to evaluate the possible effects of sodium pentaborate pentahydrate (NaB) on hair growth and reveal its effects on Wnt-1, β-catenin, vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and transforming growth factor-β1 (TGF-β1) signaling pathways, which are important molecular mechanisms involved in hair growth. METHODS Thirty-five Sprague-Dawley/Wistar albino rats were randomly divided into five groups: non-shaved control, shaved control, NaB 1 mg (shaved + NaB 1 mg elemental B/kg CA), NaB 2 mg (shaved + NaB 2 mg elemental B/kg CA), and NaB 4 mg (shaved + NaB 4 mg elemental B/kg CA). Hair density was measured using the trichoscopy method. Dorsal skin samples were examined histopathologically at the end of the 42nd day, and follicle count, follicle diameter, and subcutaneous tissue thickness were recorded. Wnt-1, β-catenin, PDGF, VEGF, TGF-β1, and collagen I levels were analyzed with the Western blot method. RESULTS In trichoscopy measurements, hair density increased in the NaB 4 mg group (90.9%). In histopathological examination, anagen follicles were observed to increase in the NaB 1 mg and 2 mg groups (p < 0.05). Follicle diameter increased in all NaB groups (p < 0.05). The Wnt-1, β-catenin, PDGF, VEGF, TGF-β1, and collagen I level increased in the NaB 1 mg and 2 mg groups (p < 0.05), but they were similar in the NaB 4 mg group compared to the control groups (p > 0.05). CONCLUSION NaB 1 and 2 mg B/kg supplementation induces the anagen phase in rats via Wnt-1, β-catenin, VEGF, PDGF, and TGF-β1 signaling pathways. NaB 4 mg B/kg suppresses these pathways and adversely affects hair growth.

Abstract
Acrylamide(AA) is a compound with wide usage areas including paper, dyes, and plastics industries. Due to its broad spectrum and water solubility suggest that this vinyl compound may cause serious environmental problems. AA was shown to exhibit neurotoxic, immunotoxic, reproductive toxicant as well as carcinogenic potency on animals. Especially in recent years, the therapeutic effects of boron and boron containing compounds like borax(BX), ulexite(ULX) and colemanite(COL) had been reported. However, the ameliorative potential by boron compounds against AA-induced toxicities had not been investigated yet. Therefore, in this investigation rainbow trout were exposed acutely to AA in the presence and absence of BX. The hematological indices and genotoxic end-points were examined in the fish blood tissue. In addition to oxidative stress response, the levels of DNA damage, CASP3, TNF-α, Nrf-2 as well as IL-6 amounts were determined in both blood and liver tissues of fish. The obtained results executed that AA induced toxic conditions in both tissues. In fact, an increase in the amount of oxidative stress and ROS, and a decrease in GSH levels were observed. AA exposure led to an increase in CASP3levels and 8-OHdG formation. It was also found that Nrf-2 pathway contributed to the initiation of oxidative stress that associated with AA-induced toxicity. On the contrary, our findings indicated that co-exposure of BX with AA elicited oxidative stress and cell death. In a conclusion BX was suggested as a useful and effective natural agent for the prevention and early treatment of AA toxicity in fish.

Abstract
Brain stroke is a highly prevalent pathology and a main cause of disability among older adults. If not promptly treated with recanalization therapies, primary and secondary mechanisms of injury contribute to an increase in the lesion, enhancing neurological deficits. Targeting excitotoxicity and oxidative stress are very promising approaches, but only a few compounds have reached the clinic with relatively good positive outcomes. The exploration of novel targets might overcome the lack of clinical translation of previous efficient preclinical neuroprotective treatments. In this study, we examined the neuroprotective properties of 2-aminoethoxydiphenyl borate (2-APB), a molecule that interferes with intracellular calcium dynamics by the antagonization of several channels and receptors. In a permanent model of cerebral ischemia, we showed that 2-APB reduces the extent of the damage and preserves the functionality of the cortical territory, as evaluated by somatosensory evoked potentials (SSEPs). While in this permanent ischemia model, the neuroprotective effect exerted by the antioxidant scavenger cholesteronitrone F2 was associated with a reduction in reactive oxygen species (ROS) and better neuronal survival in the penumbra, 2-APB did not modify the inflammatory response or decrease the content of ROS and was mostly associated with a shortening of peri-infarct depolarizations, which translated into better cerebral blood perfusion in the penumbra. Our study highlights the potential of 2-APB to target spreading depolarization events and their associated inverse hemodynamic changes, which mainly contribute to extension of the area of lesion in cerebrovascular pathologies.

Abstract
Cancer is a complex and multistage disease that causes suffering worldwide. Several mutations in tumor suppressor proteins are mostly responsible for tumorigenic development. Thus, determination of the mutations and developing a mutation targeted therapy are crucial in order to cure cancer. Moreover, since healthy cells do not have mutations in their tumor suppressor genes, mutation-specific treatment is responsible for selective treatment without harming a healthy tissue in the body. In this current study, lead borate nanoparticles (LB-Np) have been synthesized, and their effects on P53 mutant cancer cells were investigated. The synthesis method includes steps of mixing a borate buffer solution with the lead nitrate solution, washing the resulting precipitate with distilled water and eventually preparing stable LB-Np solutions. Cell viability analysis was conducted to identify the toxicity of LB-Np in HaCaT, A549, MCF7, and T47D cell lines. The changes in morphologies of breast cancer cell lines were demonstrated by using microscopical analysis. Additionally, alterations in gene expressions were determined in breast cancer cell lines after LB-Np treatment. This multidisciplinary study also identified the selective effect of LB-Np in cancer cell lines, in vitro. MTS and quantitative polymerase chain reaction assays demonstrated the effect of LB-Np were specific for p53 mutation cell line, T47D. Breast cancer cell line T47D has 580 C/T mutation which affects the activation of p53 tumor suppressor protein. However, LB-Np treatment effectively killed T47D cell lines and did not affect any other cell lines that have no p53 mutations such as MCF7, A549, and healthy HaCaT. Overall, synthesized LB-Np were found to be effective in p53-mutated cell lines and showed a remarkable selective anti-cancer activity.

Abstract
The widespread industrial use of nitrite in preservatives, colorants, and manufacturing rubber products and dyes increases the possibilities of organ toxicity. Lithium borate (LB) is known as an antioxidant and an oxidative stress reliever. Therefore, this study is aimed at examining the effect of LB on nitrite-induced hepatorenal dysfunction. Twenty-eight male Swiss mice were divided into four equal groups. Group 1, the control group, received saline. Group 2 received LB orally for 5 consecutive days at a dose of 15 mg/kg bw. Group 3, the nitrite group, received sodium nitrite (NaNO2) on Day 5 (60 mg/kg bw intraperitoneally). Group 4, the protective group (LB + NaNO2 group), received LB for 5 days and then a single dose of NaNO2 intraperitoneally on Day 5, the same as in Groups 2 and 3, respectively. Samples of blood and kidney were taken for serum analysis of hepatorenal biomarkers, levels of antioxidants and cytokines, and the expression of genes associated with oxidative stress and inflammation. NaNO2 intoxication increased markers of liver and kidney functions yet decreased reduced glutathione (GSH), superoxide dismutase (SOD), and catalase activities in blood. NaNO2 also increased the expression of tumor necrosis factor (TNF-α), interleukin-1β and interleukin-6 (IL-1β and IL-6). Pre-administration of LB protected mice from oxidative stress, lipid peroxidation, and the decrease in antioxidant enzyme activity. Moreover, LB protected mice from cytokine changes, which remained within normal levels. LB ameliorated the changes induced by NaNO2 on the mRNA of nuclear factor erythroid 2-related factor 2 (Nfr2), heme oxygenase-1 (HO-1), nuclear factor-kappa B (NF-κB), transforming growth factor-beta 2 (TGF-β2), and glutathione-S-transferase (GST) as determined using quantitative real-time PCR (qRT-PCR). These results collectively demonstrate that LB ameliorated NaNO2-induced oxidative stress by controlling the oxidative stress biomarkers and the oxidant/antioxidant state through the involvement of the Nrf2/HO-1 and NF-κB signaling pathways.

Abstract
Zn(II) complexes bearing tris[3-(2-pyridyl)-pyrazolyl] borate (Tppy) ligand (1-3) was synthesized and examined by spectroscopic and analytical tools. Mononuclear [TppyZnCl] (1) has a Zn(II) centre with one arm (pyrazolyl-pyridyl) dangling outside the coordination sphere which is a novel finding in TppyZn(II) chemistry. In complex [TppyZn(H2O)][BF4] (2) hydrogen bonding interaction of aqua moiety stabilizes the dangling arm. In addition, solution state behaviour of complex 1 confirms the tridentate binding mode and reactivity studies show the exogenous axial substituents used to form the [TppyZnN3] (3). The complexes (1-3) were tested for their ability to bind with Calf thymus (CT) DNA and Bovine serum albumin (BSA) wherein they revealed to exhibit good binding constant values with both the biomolecules in the order of 104-105 M-1. The intercalative binding mode with CT DNA was confirmed from the UV-Visible absorption, viscosity, and ethidium bromide (EB) DNA displacement studies. Further, the complexes were tested for in vitro cytotoxic ability on four triple-negative breast cancer (TNBC) cell lines (MDA-MB-231, MDA-MB-468, HCC1937, and Hs 578T). All three complexes (1-3) exhibited good IC50 values (6.81 to 16.87 μM for 24 h as seen from the MTS assay) results which indicated that these complexes were found to be potential anticancer agents against the TNBC cells.

Abstract
The reported beneficial effects of boron on mineralized tissues in animals and humans vary. Thus, a study was performed to assess whether the variability was the result of different forms of boron supplementation, method of supplementation, and increased adiposity of the rabbit experimental model. Thirty-one female New Zealand White rabbits, (aged 8 months, 2-2.5 kg weight) were fed a grain-based high energy diet containing 11.76 MJ/kg (2850 kcal/kg) and 3.88 mg boron/kg. The rabbits were randomly divided into four treatment groups: Control group was not supplemented with boron (n:7; C), and three groups supplemented with 30 mg boron/L in drinking water in the forms of borax decahydrate (Na2O4B7 10H2O, n:10; BD), borax anhydrous (Na2O4B7, n:7; Bah) or boric acid (H2BO3, n:7; BA). Cone beam micro computed tomographic (micro-CT), histological and elemental analysis was used to evaluate the bones/teeth. Results of the experiments demonstrated that boron supplementation had beneficial effects on mineralized tissue but varied with the type of treatment. Mineral density of the femur was increased by the Bah and BA treatments (p < 0.001), but only BA increased mineral density in the tibia (p = 0.015). In incisor teeth, mineral density of dentin was increased by all boron treatments (p < 0.001), and mineral density of enamel was increased by the BD and Bah treatments. Mineral analysis found that all boron treatments increased the boron concentration in tibia and femur. In the tibia, both the BD and Bah treatments decreased the iron concentration, and the BD treatment decreased the magnesium concentration. Sodium and zinc concentrations in the tibia were decreased by the Bah and BA treatments. The boron treatments did not significantly affect the calcium, copper, molybdenum, potassium phosphorus, and sulfur concentrations. The findings show that boron supplementation can have beneficial effects on mineralized tissues in an animal model with increased adiposity, which is a model of increased inflammatory stress. However, this effect varies with the form of boron supplemented, the method of supplementation, and the mineralized tissue examined.

Abstract
The developments of nanoparticle-based treatments that benefit from novel discoveries have an essential place in the regeneration of acute and chronic wounds. Furthermore, research about the treatment methods which attempt to swiftly and scarless wound recovery has increased over time. In recent years, it has been shown that metallic-based nanoparticles, especially silver and gold derived, have an accelerating effect on chronic and contaminated wound healing. The crucial factors of inducing and completion of regeneration of wound are enhanced epithelialization rate and neovascularization in the tissue. In our study, the main purpose is the investigation of the boosting effects of erbium borate nanoparticles on the wound healing process, especially scarless ones. Newly syntesized erbium borate nanoparticles (ErB-Nps) were characterized by their concentration and particle size using nanoparticle tracking analysis (NTA). In order to examine the effect of ErB-Np on wound closure, scratch assay for dermal epithelial cells and tube formation assay for endothelial cells were performed. In addition, in order to examine the effect of the ErB-Np at a molecular level, the levels of genes related to both wound healing, inflammation, and scarless wound closure were determined with the RT-PCR experiment. Consequently, it has been shown that erbium borate nanoparticles have increased the melioration speed of scar tissue and have given clues about scarless healing potential. The investigation of the regeneration potential of erbium borate nanoparticles was done via MTS assay, quantitative PCR analysis, reactive oxygen species assay, and scratch assay. Our results show that ErB-Np is a proper agent that can be used for scarless wound healing.

Abstract
BACKGROUND Obesity is one of the most popular topic in the field of research. In order to defeat this highly widespread disease, the mechanism of fat accumulation at the molecular level and its elimination are crucial. The use of boron has been showing promising results during the recent years. METHODS In this study, anti-obesity potential of Sodium Pentaborate Pentahydrate (SPP) used as a dietary supplement on BALB/c mice fed with a high-fat diet was evaluated. Mice were divided into four groups with different diets, consisting of a normal diet, a high-fat diet (HFD) (containing 60 % fat), a HFD-supplemented with 0.5 mg/g body weight (BW) of SPP and a HFD-supplemented with 1.5 mg/g body weight (BW) of SPP. The animals were then observed for 10 weeks and physically monitored, and were sacrificed at the end of the experiment for physical and physicochemical evaluation. RESULTS According to the physical parameters measured -body weight, food and water intake ratios-, the results indicate that SPP decreased weight gain in a dose dependent manner. Measurement of the hormone levels in the blood and fat accumulation in organs of mice also supported the anti-obesity effects of SPP. Expressions of adipogenesis related genes were also negatively regulated by SPP administration in white adipose tissue (WAT) tissue. CONCLUSION These findings promise a treatment approach and drug development that can be used against obesity when SPP is used in the right doses. As a future aspect, clinical studies with SPP will reveal the effect of boron derivatives on obesity.

Abstract
Bacteriophages (phages) are a specific type of viruses that infect bacteria. Because of growing antibiotic resistance among bacterial strains, phage-based therapies are becoming more and more attractive. The critical problem is the storage of bacteriophages. Recently, it was found that bacteriophages might adsorb on the surfaces of plastic containers, effectively decreasing the titer of phage suspensions. Here, we showed that a BOA nanocomposite (gold nanoparticles embedded in polyoxoborate matrix) deposited onto the inner walls of the containers stabilizes phage suspensions against uncontrolled adsorption and titer decrease. Additionally, BOA provides antibacterial and antifungal protection. The application of BOA assures safe and sterile means for the storage of bacteriophages.

Abstract
Boron is an essential trace element in cellular metabolism; however, the molecular mechanism of boron in the heart is unclear. In this study, we examined the effect of sodium tetraborate (as boron source) as a possible protective agent or competitive inhibitor of cardiac hypertrophy in an in vitro murine model. We evaluated different previously reported sodium tetraborate concentrations and it was found that 13 μM improves viability without affecting the cellular structure. We demonstrated that cardiomyocytes pretreated with sodium tetraborate prevents cellular damage induced by isoproterenol (cardioprotective effect) by increasing proliferation rate and inhibiting apoptosis. In addition, the reduction of the expression of the α1AR and β1AR adrenergic receptors as well as Erk1/2 was notable. Consequently, the expression of the early response genes c-myc, c-fos and c-jun was delayed. Also, the expression of GATA-4, NFAT, NKx2.5 and myogenin transcription factors involved in sarcomere synthesis declined. In contrast, cardiomyocytes, when treated simultaneously with sodium tetraborate and isoproterenol, did not increase their size (cytoplasmic gain), but an increase in apoptosis levels was observed; therefore, the proliferation rate was reduced. Although the mRNA levels of α1AR and β1AR as well as Erk1/2 and Akt1 were low at 24 h, their expression increased to 48 h. Notably, the mRNA of expression levels of c-myc, c-fos and c-jun were lower than those determined in the control, while the transcription factors GATA-4, MEF2c, Nkx2.5, NFAT and CDk9 were determined in most cells. These results suggest that pretreatment with sodium tetraborate in cardiomyocytes inhibits the hypertrophic effect. However, sodium tetraborate attenuates isoproterenol induced hypertrophy damage in cardiomyocytes when these two compounds are added simultaneously.

Abstract
The ulexite (UX), a borate mineral, is used as boron source and commonly used in various industrial processes. The hematological and hepatic effects of UX were investigated by exposing adult zebrafish to UX (5, 10, 20 and 40 mg/L) over 96 hours. The blood and liver tissues were taken at the end of the trial period then micronucleus (MN) rates, oxidative DNA damage (8-OHdG), apoptosis (Caspase-3), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), myeloperoxidase (MPO), paraoxonase (PON), arylesterase (AR) and lipid peroxidation (MDA) levels were determined. Genotoxic damage by UX occurred only at 40 mg/L in the blood MN assay. Oxidative stress, oxidative DNA damage and apoptosis in liver also occurred at this dose. Moreover, 5-20 mg/L doses led to decreases of DNA damage and apoptosis levels via promoting antioxidant system in liver tissues. UX exhibits beneficial roles on blood and liver tissues of zebrafish at relatively lower doses, which may be relevant to nutritional and medicinal industries.

Abstract
Bacterial soft rot caused by the bacteria Dickeya and Pectobacterium is a destructive disease of vegetables, as well as ornamental plants. Several management options exist to help control these pathogens. Because of the limited success of these approaches, there is a need for the development of alternative methods to reduce losses. In this study, we evaluated the effect of potassium tetraborate tetrahydrate (PTB) on the growth of six Dickeya and Pectobacterium spp. Disc diffusion assays showed that Dickeya spp. and Pectobacterium spp. differ in their sensitivity to PTB. Spontaneous PTB-resistant mutants of Pectobacterium were identified and further investigation of the mechanism of PTB resistance was conducted by full genome sequencing. Point mutations in genes cpdB and supK were found in a single Pectobacterium atrosepticum PTB-resistant mutant. Additionally, point mutations in genes prfB (synonym supK) and prmC were found in two independent Pectobacterium brasiliense PTB-resistant mutants. prfB and prmC encode peptide chain release factor 2 and its methyltransferase, respectively. We propose the disruption of translation activity due to PTB leads to Pectobacterium growth inhibition. The P. atrosepticum PTB-resistant mutant showed altered swimming motility. Disease severity was reduced for P. atrosepticum-inoculated potato stems sprayed with PTB. We discuss the potential risk of selecting for bacterial resistance to this chemical.

Abstract
Tumor microenvironment, genetic, and non-genetic factors are responsible for the atypical metabolic feature of cancer cells. Aberrant activity of PI3K/Akt pathway, increased glycolytic flux, and decreased intracellular pH gradient are the leading causes of this feature. Calcium Fructoborate (CaFB), a sugar-borate ester, has major benefits for human health. The aim of this study was to explore the implication of CaFB on experimentally induced skin cancer in vivo. According to the treatment, 92 female Balb-c mice are divided into six groups: control, CaFB (3 mg/kg/day), 7,12-Dimethylbenz(a)anthracene (DMBA)+12-O-tetradecanoylphorbol-13-acetate (TPA) (97.5 nmol DMBA, 6.5 nmol TPA), T1: CaFB+DMBA+TPA (3 mg/kg/day CaFB together with DMBA), T2: DMBA+CaFB+TPA (3 mg/kg/day CaFB together with TPA), T3: DMBA+TPA+CaFB (3 mg/kg/day CaFB after tumor formation). Topical DMBA and TPA application resulted in a significant increase in the protein levels, immunoreactivity, and mRNA expression of HRAS, HIF1α, Akt, and PTEN (p < 0.05). Moreover, an increase in the number of TUNEL-positive cells was observed in DMBA-TPA group compared with the control group (p < 0.05). CaFB application reduced the protein levels, immunoreactivity, and mRNA expressions of HRAS, HIF1α, Akt, and PTEN and also decreased the number of TUNEL-positive cells. Recent evidence obtained from our study validated that CaFB treatment may have skin cancer-preventing effect.

Abstract
Obesity is a major public health problem worldwide and a risk factor for certain diseases, including cardiovascular disease, diabetes, cancer, and depression. Unfortunately, currently available anti-obesity drugs have failed in the long-term maintenance of weight control. It has been a challenge to design novel drugs that could potentially treat obesity or prevent uncontrolled weight-gain which lies underneath the pathology of obesity. Since obesity in a way is a consequence of the accumulating new mature adipocytes from undifferentiated precursors which is a process also termed as adipogenesis, drugs that might control adipogenesis could be beneficial for the treatment of obesity. In the current study, combined effect of sodium pentaborate pentahydrate (NaB) and pluronic F68 on adipogenic differentiation was examined by administering various combinations of the two agents to human adipose-derived stem cells (hADSCs) in in vitro. Immunocytochemistry and quantitative RT-PCR were performed to evaluate the levels of adipogenesis-promoting genes such as peroxisome proliferator-activated receptor-γ (PPARγ), fatty acid binding protein (FABP4), and adiponectin. Results indicated that expressions of all these three genes were restrained. Furthermore, Oil Red O staining revealed that lipid vesicle formation was reduced in hADSCs treated with differentiation medium containing NaB/F68 combination. Finally, expression levels of Hippo pathway kinases Lats2, MST1, and scaffold protein Sav1 were reduced in these cells, suggesting a possible link between Hippo pathway-dependent downregulation of PPARγ and the NaB/F68 treatment. Herein, we showed that combination of NaB and F68 curtails adipocyte differentiation by inhibiting the adipogenic transcriptional program leading to a decrease in lipid accumulation in adipocytes even at very low doses, thereby uncovered a striking opportunity to use this combination in obesity treatment.

Abstract
Diabetes mellitus is worldwide disease. The life of diabetic patients are dependent on exogenous insulin. Pancreas or particularly islet transplantations are performed for reducing external insulin dependency. External substances are also used to protect the β-cells from the death or increase insulin secretion. In the current study, two different boron containing compounds (sodium pentaborate pentahydrate-NaB and boric acid-BA) were investigated for their effect on pancreatic cells in terms of pro-apoptotic and anti-apoptotic markers, genes related to insulin production mechanism, pancreatic development and glucose metabolism, some antioxidant enzymes, and genes for the initiation of diabetes, insulin secretion and antioxidant enzyme activities in vitro. The results revealed that boron containing compounds did not lead to apoptosis. On the contrary, they increased cell viability, antioxidant enzyme activities and the level of genes related to insulin production. Overall evaluation, data in the current study showed that boron containing compounds might be promising therapeutic agents for type 1 diabetes. However, additional investigations are strictly needed to elucidate molecular mechanisms of boron containing compounds.

Abstract
Over the past years, adipose tissue has become an invaluable source of mesenchymal stem cells (MSCs) due to development of improved isolation methodologies. In a recent work, our group established a primary culture of human adipose-derived stem cells (hADSCs), which were characterized for their stem cell characteristics in detail and studied their myogenic differentiation potential in presence of boron. In the current study, we focused on the effects of a boron-containing compound, sodium pentaborate pentahydrate (NaB), on the adipogenic differentiation of hADSCs. Incorporation of boron in various chemical derivates has been a novel interest in drug-discovery attempts due to increasing number of reports on their anticancer, antibacterial, antiviral, and antifungal activities. In this report, a striking suppressive activity of boron on adipogenic differentiation of hADSCs is observed in a dose-dependent manner. Higher concentrations of NaB (20, 50, and 100 μg/mL (68, 170 and 340 μM)) resulted in a progressive decrease of lipid deposition, suppressed master regulators of adipogenesis transcriptional programming at the mRNA and protein levels, while having no evident cytotoxicity on the cells. The findings of this study are encouraging to undertake further investigations on potential beneficial effects boron in terms of its impact on normal and dysfunctional adipose biology. In that respect, these results pave the path to evaluate boron-based compounds in prevention and treatment of obesity which is a modern age pandemic that is predominant worldwide and found in strong association with comorbidities, including type 2 diabetes, hypertension, cardiovascular disease, cancers, and others."

Abstract
Sugar-borates (SBs) are mono- or di-sugar-borate esters (SBEs) comprised of one or two monosaccharide molecules linked to a boron (B) atom. SBEs occur naturally in commonly consumed herbs, vegetables, fruits, seeds, and nuts and, other than greatly varying levels of B found in local drinking water, are the primary natural dietary sources of B-containing molecules in humans. To date, the most studied SBE is calcium fructoborate (CaFB). CaFB represents an important example of how organic B-containing molecules are significantly distinct from their inorganic counterparts. During these past two decades, CaFB has been researched for its physical and biochemical characteristics, safety, and clinical outcomes. Results of these researches are presented and discussed herein. CaFB has been characterized using Fourier-transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), high-performance thin-layer chromatography (HPTLC), nuclear magnetic resonance (NMR), liquid chromatography-multistage accurate mass spectrometry (LC-MSn), X-ray diffraction (XRD), Raman spectroscopy, and inductively coupled plasma (ICP) in non-biological and biological specimens. Potential health benefits of CaFB have been clinically investigated in pilot and efficacy studies demonstrating (i) significant reductions in knee discomfort and improved flexibility within 7, 14, and 90 days and (ii) significant effect on blood levels of inflammatory, cardiovascular, and other biomarkers. These studies support the use of CaFB as a dietary supplement for the management of joint discomfort. CaFB is presented here in order to illustrate how physiological benefits are imparted by distinct organic boron-containing molecules rather than solely by the element B itself. Considering recent National Health and Nutrition Examination Survey (NHANES) data reporting increases in age-related joint pain and an increasing elderly demographic, SBEs offer potential for safe, natural, and effective management of joint discomfort and improved mobility in human and animal health applications. Several of these studies may also open new opportunities for use of SBEs for health benefits beyond joint health.

Abstract
Heavy metals have harmful effects on health of both ecosystems and organisms to their accumulation ability. Copper (Cu) is an essential element for organism survival, but EPA considers Cu as a priority pollutant. On the other hand, boron has well-defined biological effects in living organisms including cytoprotection and genoprotection, although borax (BX) metabolism is poorly described in fish. Moreover, the effects of boron supplementation against Cu-induced hematotoxicity and DNA damage in aquatic organisms are still undetermined. Therefore, the main aim of this study was to provide an overview of the strategy for therapeutic potential of BX against Cu exposure in rainbow trout, Oncorhynchus mykiss. For this aim, fish were fed with different doses of BX and/or copper (1.25, 2.5, and 5 mg/kg of BX; 500 and 1000 mg/kg of Cu) for 21 days in pretreatment and combined treatment options. At the end of the treatments (pre and combined), the hematological index (total erythrocytes count (RBC), total leucocytes count (WBC), hemoglobin (Hb), hematocrit (Hct), total platelet count (PLT), mean cell hemoglobin concentration (MCHC), mean cell hemoglobin (MCH), mean cell volume (MCV)), oxidative DNA damage (8-hydroxy-2-deoxyguanosine (8-OHdG)), and nuclear abnormalities in blood samples of treated and untreated fish were investigated. The statistically significant (p < 0.05) and dose-dependent increases in hematological indices, 8-OH-dG level, and rates of nuclear abnormalities were observed after exposure to Cu in both treatment group fish as compared to untreated group. On the contrary, treatments with BX doses alone did not alter these hematological and DNA damage endpoints. Moreover, both pretreatment and combined treatments with BX significantly alleviated Cu-induced hematotoxicity and genotoxicity. In a conclusion, the obtained data firstly revealed that borax exhibited hematoprotective and genoprotective effects against copper-induced toxicity in fish.

Abstract
The aim of this study was to evaluate the effectiveness of borax (BX) against heavy metal exposure on the transcriptional and biochemical reaction in vivo and alleviating effect on gill and liver tissues of rainbow trout. Due to this aim, fish were fed with different level of BX and/or copper (Cu) (1.25, 2.5 and 5 mg/kg of BX; 500 and 1000 mg/kg of Cu) for 21·days in pre- and co-treatment options. The transcriptional parameters [(heat-shock protein 70 (hsp70), and cytochromes P450 (cyp1a), glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT))], antioxidant enzyme activities (SOD, CAT and GPx), malondialdehyde (MDA), oxidative DNA damage (8-hydroxy-2'-deoxyguanosine (8-OHdG) and caspase-3 levels were investigated in different tissues samples of treated and control fish. Our results revealed that antioxidant enzyme activity was increased and levels of 8-OHdG, Caspase-3 and MDA were decreased in the BX and BX combined groups as compared to the copper combination group and to copper-only application during pre- and co-treatment (p < 0.05). Similarly, hsp70 and cyp1a gene expressions were decreased after treatment with BX. As conclusion, we suggest that borax itself is not an antioxidant it supportes antioxidant defense mechanism of fish disrupted by heavy metals.

Abstract
Oxidative stress, specifically lipid peroxidation, is a major driving force in neurodegenerative processes. However, the exact role of lipid peroxidation remains elusive as reliable real-time detection and quantification of lipid peroxyl radicals proves to be challenging in vitro and in vivo. Motivated by this methodological limitation, we have optimized conditions for real-time imaging and quantification of lipid peroxyl radical generation in primary neuron cultures using the lipophilic fluorogenic antioxidant H4BPMHC (8-((6-hydroxy-2,5,7,8-tetramethylchroman-2-yl)-methyl)-1,5-di(3-chloropropyl)-pyrromethene fluoroborate), an α-tocopherol analog probe. By subjecting neurons to different antioxidant conditions in the presence and absence of lipid peroxidation inducing stressors (Haber-Weiss reagents), we maximized H4BPMHC sensitivity and confirmed its potential to temporally resolve subtle and marked differences in lipid peroxidation levels in real-time. Herein we report imaging and quantification of homeostatic and induced lipid peroxidation in primary neuron cultures, supporting the use of this probe for investigating healthy and diseased states. Overall these results provide the necessary foundation and impetus towards using H4BPMHC for elucidating and mapping lipid peroxyl radical contributions to ROS-associated pathological processes in neurons.

Abstract
We aimed to investigate the modulating effects of dietary borax on the pathways in rainbow trout brain exposed to copper. For this aim, a comprehensive assessment was performed including biochemical (acetylcholinesterase (AChE), malondialdehyde (MDA), oxidative DNA damage (8-hydroxy-2'-deoxyguanosine (8-OHdG), and caspase-3 levels) and transcriptional parameters (heat shock protein 70 (HSP70) and cytochromes P450 (CYP1A), glutathione peroxidase (gpx), superoxide dismutase (sod), and catalase (cat)) parameters and immunohistochemically staining of 8-OHdG. Special fish feed diets were prepared for the trial. These diets contained different concentrations of borax (1.25, 2.5, and 5 mg/kg) and/or copper (500 and 1000 mg/kg) at the period of pre- and co-treatment strategies for 21 days. At the end of the treatment periods, brain tissue was sampled for each experimental group. As a result, the biochemical parameters were increased and AChE activity decreased in the copper and copper-combined groups in comparison with the control group and also with only borax applications (p < 0.05). We observed an increase or decrease in particular biochemical parameters for the borax group in every application and we established that borax had protective effect against copper toxicity by decreasing and/or increasing the relevant biochemical parameters in brain tissue of fish. The biochemical results of borax and its combinations corresponded to the observations of gene expression data, which similarly concluded that HSP70 and CYP1A genes were strongly induced by copper (p < 0.05). In addition, the expression levels of the sod, cat, and gpx genes in the fish brains exposed to borax and the borax combination groups were significantly higher than the only copper-treated groups. In conclusion, borax supplementation provided significant protection against copper-induced neurotoxicity in trout.

Abstract
There is an urgent demand for wound healing biomaterials because of the increasing frequency of traffic accidents, industrial contingencies, and natural disasters. Borate bioactive glass has potential applications in bone tissue engineering and wound healing; however, its uncontrolled release runs a high risk of rapid degradation and transient biotoxicity. In this study, a novel organic-inorganic dressing of copper-doped borate bioactive glass/poly(lactic- co-glycolic acid) loaded with vitamin E (0-3.0 wt % vitamin E) was fabricated to evaluate its efficiency for angiogenesis in cells and full-thickness skin wounds healing in rodents. In vitro results showed the dressing was an ideal interface for the organic-inorganic mixture and a controlled release system for Cu2+ and vitamin E. Cell culture suggested the ionic dissolution product of the copper-doped and vitamin E-loaded dressing showed the best migration, tubule formation, and vascular endothelial growth factor (VEGF) secretion in human umbilical vein endothelial cells (HUVECs) and higher expression levels of angiogenesis-related genes in fibroblasts in vitro. Furthermore, this dressing also suggested a significant improvement in the epithelialization of wound closure and an obvious enhancement in vessel sprouting and collagen remodeling in vivo. These results indicate that the copper-doped borate bioactive glass/poly(lactic- co-glycolic acid) dressing loaded with vitamin E is effective in stimulating angiogenesis and healing full-thickness skin defects and is a promising wound dressing in the reconstruction of full-thickness skin injury.

Abstract
This study was carried out to determine the protective effects of lithium borate (LTB) on blood parameters and histopathological findings in experimentally induced acute cadmium (Cd) toxicity in rats. Twenty-eight male Wistar albino rats were used, weighing 200-220 g, and they were randomly divided into four groups, including one control and the following three experimental groups: a Cd group (0.025 mmol/kg), a LTB group (15 mg/kg/day orally for 5 days), and a LTB + Cd group (15 mg/kg/day orally for 5 days and Cd 0.025 mmol/kg by intraperitoneal injection on the fifth day). All the rats in the study were anesthetized with ketamine at the end of the sixth day, blood was taken from their hearts, and then the rats were decapitated. The values in the control and LTB group were usually close to each other. White blood cell (WBC), neutrophil %, and C-reactive protein (CRP) levels increased in the Cd and LTB + Cd groups while lymphocyte and monocyte levels decreased in a statistically significant manner, in comparison to the other groups. It was determined that the levels of red blood cells (RBCs), hematocrit (Htc), and hemoglobin (Hb) did not change in the groups. The levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the Cd and LTB + Cd groups significantly increased, in comparison to the other groups, while the glucose, alkaline phosphatase (ALP), albumin (ALB), and total protein (TP) levels decreased. According to histopathological findings in the control and LTB groups, the liver and kidney tissues were found to have normal histological structures. In the Cd group, severe necrotic hemorrhagic hepatitis, mild steatosis, and mononuclear cell infiltration were detected in the liver. In the LTB + Cd group, degeneration and mild mononuclear cell infiltration were found in the liver. Regarding the kidney tissue in the Cd group, severe intertubular hyperemia in both kidney cortex and medulla, as well as degeneration and necrosis in the tubulus epithelium, was observed. In the LTB + Cd group, mild interstitial hyperemia and mononuclear cell infiltration was detected. Resultantly, it can be said that LTB at this dose has non-toxic effects and some beneficial effects for liver and kidney damage caused by acute Cd toxicity.

Abstract
Pyrogallol is a polyphenol that generates the superoxide anion. In this study, we investigated the influence of pyrogallol on human platelets. Our data showed that exposure of platelets to pyrogallol induced numerous manifestations of apoptosis including depolarization of mitochondrial inner membrane and release of cytochrome c from the mitochondria. Pyrogallol also induced downstream extra-mitochondrial apoptotic responses, including activation of caspase-3 and phosphatidylserine exposure on the outer leaflet of the plasma membrane. Addition of glutathione significantly rescued cells from pyrogallol- induced apoptosis, as evidenced by a decrease of all markers of apoptosis. Thus, pyrogallol appears to produce depletion of intracellular glutathione content in platelets, the main non-protein antioxidant in the cells. Furthermore, inhibition of γ-glutamyl transpeptidase, an enzyme that plays the main role in the cellular supply of glutathione, reverted the glutathione (GSH) protection over platelet apoptosis. Our results indicate that pyrogallol induces apoptosis by suppressing the natural anti-oxidation in human platelets.

Abstract
Our objective was to evaluate the short-term effects of calcium fructoborate (CFB) on gait, joint range of motion, serum inflammatory markers, and owner perception of pain in client-owned dogs. We used 59 osteoarthritic dogs with impairment, with dogs being randomly assigned to 4 treatments: placebo (60 mg fructose; = 15), low dose (69 mg CFB; = 14), high dose (127 mg CFB; = 14), or combination (69 mg CFB, 500 mg glucosamine hydrochloride and 200 mg chondroitin sulfate; = 16). Dogs up to 22.9 kg received 1 capsule/d, while dogs weighing 23 to 50 kg received 2 capsules/d. A physical examination, radiographs, goniometry measurements, gait analysis, blood sample collection, and a canine brief pain inventory questionnaire were performed on d 0 and 28. Change from baseline values were statistically analyzed among groups. After 28 d, dogs fed the low and high doses had an improved ( < 0.05) ability to rise from a lying position compared to placebo. Dogs fed the high dose also had a greater ( = 0.05) increase in soluble receptor for advanced glycation end products concentration than dogs fed the placebo. Sub-analysis of only large dogs (> 23 kg) showed that dogs fed the low dose had decreased ( < 0.05) pain severity score and pain at its worst compared to dogs fed the placebo. Large dogs fed the low dose also were shown to improve ( < 0.05) in their ability to rise from a lying position compared to dogs fed the placebo. Overall, CFB supplementation was well-tolerated and may aid in mitigating joint discomfort in dogs.

Abstract
Evidences about the preventive and therapeutic effects of boron compounds on cancer have been increasing in the last years. Although calcium fructoborate (CaFB) is used as a nutritional supplement, data about its preventive and therapeutic effects on neoplastic transformations are limited. In the present study, the various concentrations of CaFB were applied to the MDA-MB-231 metastatic breast cancer cell line. First, we examined the cytotoxic effect and IC50 value of CaFB by MTT assay. For the evaluation of the DNA damage, apoptosis and metastatic potential, expression levels of ATM, pATM, PARP, p53, p-p53, caspase-3, caspase-9, and VEGF were investigated by using immunoblotting and immunohistochemical methods. Cell viability was significantly reduced at 50 μM CaFB treatment. pATM, p-p53, and caspase-9 levels increased significantly in all groups; furthermore, there was approximately 12.5-, 2.4-, and 10.7-fold increase, respectively, for 100 μM CaFB treatment. ATM and p53 levels did not change with CaFB treatment, but PARP levels significantly 2.5-fold decreased. While VEGF immunoreactivity decreased in all groups, significant increase in caspase-3 immunoreactivity was observed only in the group treated with 50 μM CaFB (p < 0,001). Our results imply that CaFB may have therapeutic potential as well as preventive benefits in cancer.

Abstract
Obesity is a worldwide medical problem resulting in serious morbidity and mortality involving differentiation of pre-adipocytes into mature adipocytes (adipogenesis). Boron treatment has been reported to be associated with weight reduction in experimental animals; however, its effects on pre-adipocyte differentiation and anti-adipogenic molecular mechanisms are unknown. In this study, we demonstrate the inhibitory activities of boric acid (BA) and sodium pentaborate pentahydrate (NaB) on adipogenesis using common cellular models. Boron treatment repressed the expression of adipogenesis-related genes and proteins, including CCAAT-enhancer-binding protein α and peroxisome proliferator-activated receptor γ, by regulating critical growth factors and the β-catenin, AKT, and extracellular signal-regulated kinase signaling pathways. In addition, although boron treatment did not induce apoptosis in pre-adipocytes, it depressed mitotic clonal expansion by regulation of cell cycle genes. Overall, these data offer promising insights into the prevention/treatment of obesity and associated diseases.

Abstract
Ionic liquids (ILs) are important for their antimicrobial activity and are found to be toxic to some microorganisms. To shed light on the mechanism of their activities, the interaction of an imidazolium-based IL 1-butyl-3-methylimidazolium tetrfluoroborate ([BMIM][BF4]) with E. coli bacteria and cell-membrane-mimicking lipid mono- and bilayers has been studied. The survival of the bacteria and corresponding growth inhibition are observed to be functions of the concentration of the IL. The IL alters the pressure-area isotherm of the monolayer formed at an air-water interface by the 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) lipid. The in-plane elasticity of the lipid layer is reduced as a consequence of the insertion of this IL. The X-ray reflectivity study from a polymer-supported lipid bilayer shows strong perturbation in the self-assembled structure of the bilayer due to the interaction. As a consequence, there is a considerable decrease in bilayer thickness and a corresponding increase in electron density. These results, however, depend on the chain configurations of the lipid molecules.

Abstract
Calcium fructoborate (CF), a natural sugar-borate ester found in fresh fruits and vegetables, is a source of soluble boron. CF contains three forms of borate (diester, monoester, and boric acid) and all are biologically active, both at the intracellular (as free boric acid) and extracellular level (as fructose-borate diester and monoester). At the cellular and molecular level, CF is superior to the boric acid/borate, exhibiting a complex "protective" effect against inflammatory response. CF is commercially available in the USA as a "nature-identical" complex, an active compound for dietary supplements. It provides effective and safe support against the discomfort and lack of flexibility associated with osteoarticular conditions (arthritis and joint degeneration), and improves Western Ontario and McMaster Universities Osteoarthritis (WOMAC) and McGill indexes. In addition, orally administered CF is effective in ameliorating symptoms of physiological response to stress, including inflammation of the mucous membranes, discomfort associated with osteoarthritis disorders, and bone loss, and also for supporting cardiovascular health. Clinical studies have exhibited the ability of CF to significantly modulate molecular markers associated with inflammatory mechanisms, mainly on the elevated serum levels of C-reactive protein (CRP).

Abstract
Patients with acute wounds often delay seeking medical assistance until an incapacitating infection has developed. When such patients come for help at a remote Christian clinic in northern Ghana, West Africa, the goals of care are to resolve and prevent a return of infection, decrease pain, enable an immediate return to normal activities, and facilitate healing. Because the local protocol of care, Edinburgh University Solution of Lime (EUSOL)-soaked gauze, did not meet these goals, the author tried using a variety of donated wound dressing regimens. Ultimately, polymeric membrane dressings (PMDs) were observed to meet patient care needs while also reducing clinic staff time and resources, and a PMD protocol of care was developed. Three (3) representative patients who presented with acute wounds and infection are described: a 20-year-old man with a hand abscess, a 16-year-old boy with a malleolus wound, and an approximately 20-year-old woman with an injection abscess, all otherwise relatively healthy, albeit undernourished. All 3 patients re- ceived oral antibiotics, their wounds were initially cleansed and debrided, and an appropriate configuration of either regular or silver-containing PMDs was applied to all exposed wound surfaces. Dressing changes were scheduled based upon the personalized plan of care. In all 3 patients, the pain-relieving properties of PMDs allowed resumption of activi- ties within 1 day of initiating treatment, the dressings' continuous wound cleansing system kept the wounds clean and free of infection despite the challenging environment, and the wounds healed steadily. Managing infected acute wounds with PMDs through complete wound closure was time efficient for clinic staff and met all 4 major patient goals of care. Randomized, controlled studies to compare wound and quality of life outcomes in patients whose infected wounds are managed with PMDs compared with those whose wounds are managed with other advanced dressings are warranted.

Abstract
A key role of boron in plants is to cross-link the cell wall pectic polysaccharide rhamnogalacturonan-II (RG-II) through borate diester linkages. Phenylboronic acid (PBA) can form the same reversible ester bonds but cannot cross-link two molecules, so can be used as an antagonist to study the function of boron. This study aimed to evaluate the effect of PBA on apple (Malus domestica) pollen tube growth and the underlying regulatory mechanism. We observed that PBA caused an inhibition of pollen germination, tube growth and led to pollen tube morphological abnormalities. Fluorescent labeling, coupled with a scanning ion-selective electrode technique, revealed that PBA induced an increase in extracellular Ca2+ influx, thereby elevating the cytosolic Ca2+ concentration [Ca2+]c and disrupting the [Ca2+]c gradient, which is critical for pollen tube growth. Moreover the organization of actin filaments was severely perturbed by the PBA treatment. Immunolocalization studies and fluorescent labeling, together with Fourier-transform infrared analysis (FTIR) suggested that PBA caused an increase in the abundance of callose, de-esterified pectins and arabinogalactan proteins (AGPs) at the tip. However, it had no effect on the deposition of the wall polymers cellulose. These effects are similar to those of boron deficiency in roots and other organs, indicating that PBA can induce boron deficiency symptoms. The results provide new insights into the roles of boron in pollen tube development, which likely include regulating [Ca2+]c and the formation of the actin cytoskeleton, in addition to the synthesis and assembly of cell wall components.

Abstract
Oxidative stress a major cause of fluoride induced toxicity and mitochondrial impairment in common in experimental rats during chronic exposure of fluoride. Attempts have been made in the present experiment to diminish oxidative damage, combined therapy with (+)-catechin hydrate (an antioxidant) and sodium meta borate (chelator) were used. Fluoride intoxication in rats was performed by using 13mg/kg NaF and both antioxidant CH and chelator SMB were used at a concentration of 8.98μM/kg body weight. Mixture of CH and SMB in free or in PLGA nanocapsule encapsulated form were prepared. The efficacies of those formulations were tested in combating free radical mediated oxidative insult produced by sodium fluoride (NaF). The amalgamated therapy used in this experiment was shown to reduce fluoride levels in liver, brain and kidney from 9.5, 5.5, 6.3μg/g to 4.6, 2, 2.6μg/g, respectively. Our result indicated that the combined chelator and antioxidant therapy in nanocapsulated drug delivery system could provide a projection in combating fluoride induced mitochondrial impairment in rat model.

Abstract
PURPOSE To evaluate the effect of chlorhexidine or glutaraldehyde pretreatment on the bonding stability of selfetching and etch-and-rinse adhesives to bleached dentin. MATERIALS AND METHODS The occlusal surface of 80 third molars was abraded to expose a flat mid-dentin surface, which was then subjected to a bleaching procedure using 20% hydrogen peroxide and sodium perborate for 14 days. Afterwards, the specimens were kept in distilled water, followed by application of either a three-step etchand- rinse (Adper Scotchbond Multi-Purpose Plus, SBMP) or a two-step self-etching (Clearfil SE Bond, CSE) adhesive system. For each approach, the bleached dentin was treated with chlorhexidine or glutaraldehyde, or left untreated, prior to the adhesive procedure. Unbleached dentin was used as a control. Composite cylinders were built up over the adhesive-covered dentin followed by parallel sectioning of specimens to obtain 1-mm slices. The slices were trimmed to obtain hourglass-shaped specimens with approximately 1.0 mm2 of bonding interface. Half of the specimens were subjected to microtensile bond strength (μTBS) testing after 24 h, while the other half were stored in distilled water for 3 months prior to the μTBS test. The mode of failure was analyzed using optical microscopy. RESULTS For the SBMP protocol, the highest μTBS was achieved with glutaraldehyde-treated dentin, and the same μTBS values were maintained after 3 months of storage. For the CSE protocol, the highest μTBS was obtained with chlorhexidine-treated dentin. CONCLUSION Glutaraldehyde and chlorhexidine pretreatment should be considered to improve the μTBS of adhesives to bleached dentin, while the pretreatment effect was adhesive dependent.

Abstract
A novel inorganic nanocomposite material, called BOA, which has the form of small building blocks composed of gold nanoparticles embedded in a polyoxoborate matrix, is presented. It is demonstrated that cotton wool decorated with the BOA nanocomposite displays strong antibacterial activity toward both Gram-positive and -negative bacteria strains. Importantly, the modified cotton does not release any toxic substances, and the bacteria are killed upon contact with the fibers coated with the BOA. Toxicity tests show that the nanocomposite--in spite of its antiseptic properties--is harmless for mammalian cells. The presented method of surface modification utilizes mild, environmentally friendly fabrication conditions. Thus, it offers a facile approach to obtain durable nontoxic antiseptic coatings for biomedical applications.

Abstract
Nowadays, large part of the population in Hungary is affected by the dry eye disease or symptom. Most of these magistral pharmaceuticals (FoNo VI) compared to the industrial products have disadvantages. They are not compatible with contact lenses, because of the preservatives and after opening they can be used only for seven days. In our experiments we used sodium-perborate as preservative, which could be a solution for the problems mentioned above. Our results indicate that the sodium-perborate sterilized the solution and resists against microbiological contamination. Its preservative effect maintained for more than four weeks. Our further purpose is to develop a new pharmacy drug preparation method to find an effective solution for the microbiological stability-related problems of artificial tears.

Abstract
In vitro, animal, and human experiments have shown that boron is a bioactive element in nutritional amounts that beneficially affects bone growth and central nervous system function, alleviates arthritic symptoms, facilitates hormone action and is associated with a reduced risk for some types of cancer. The diverse effects of boron suggest that it influences the formation and/or activity of substances that are involved in numerous biochemical processes. Several findings suggest that this influence is through the formation of boroesters in biomolecules containing cis-hydroxyl groups. These biomolecules include those that contain ribose (e.g., S-adenosylmethionine, diadenosine phosphates, and nicotinamide adenine dinucleotide). In addition, boron may form boroester complexes with phosphoinositides, glycoproteins, and glycolipids that affect cell membrane integrity and function. Both animal and human data indicate that an intake of less than 1.0mg/day inhibits the health benefits of boron. Dietary surveys indicate such an intake is not rare. Thus, increasing boron intake by consuming a diet rich in fruits, vegetables, nuts and pulses should be recognized as a reasonable dietary recommendation to enhance health and well-being.

Abstract
Degradation of acetamiprid in wastewater was studied in a dielectric barrier discharge (DBD) reactor. This reactor produces ultraviolet light and reactive species like ozone (O₃) can be used for the treatment of wastewater. We examined the factors that could affect the degradation process, including the discharge power, and the initial concentrations of acetamiprid, and O₃ which is generated by the DBD reactor. We also investigated the effect of adding Na₂B₄O₇ as a radical scavenger to probe the role of hydroxyl radical in the reaction. The results indicated that acetamiprid could be removed from aqueous solution effectively and hydroxyl radicals played an important role during the degradation by the low temperature plasma. The degradation process of acetamiprid fits the first-order kinetics. The degradation efficiency was 83.48 percent at 200 min when the discharge power was 170 W and the initial acetamiprid concentration was 50 mg/L. The removal efficiency of acetamiprid decreased with the increasing concentration of Na₂B₄O₇ because B₄O₇(2-) is an excellent radical scavenger that inhibited the generation of OH during the DBD process. The removal efficiency of acetamiprid improved in the presence of O₃. The main reason was that O₃ can oxidize certain organic compounds directly or indirectly by generating hydroxyl radicals. The degradation products of acetamiprid were characterized qualitatively and quantitatively using high performance liquid chromatography, mass spectrometry and UV-vis spectroscopy.

Abstract
Inflammation has been identified as a possible contributory factor to disruption of the normal bone remodeling process, a process essential to healthy bone mineral density. Several large population-based clinical studies have specifically shown that levels of C-reactive protein, an immune recognition protein that is a sensitive marker of inflammation, are inversely and independently associated with total bone mineral density. The evidence suggests that control of C-reactive protein levels may contribute to bone health by protecting against inflammation's disruption of the equilibrium between bone resorption and bone deposition. Calcium fructoborate, a patented complex of calcium, fructose, and boron found naturally in fresh and dried fruits, vegetables and herbs, and wine, is a sugar-borate ester. A growing body of peer-reviewed, published clinical research indicates that the calcium fructoborate significantly reduces serum levels of the C-reactive protein in humans, suggesting that this unique plant-mineral complex may contribute to bone health by controlling the inflammation associated with loss of bone mineral density.

Abstract
The aim of this work was to study the inhibition effect of boric acid and sodium borate on the treatment of boron containing synthetic wastewater by a down flow aerobic fixed bed biofilm reactor at various chemical oxygen demand (COD)/boron ratios (0.47-20.54). The inhibitory effect of boron on activated sludge was evaluated on the basis of COD removal during the experimental period. The biofilter (effective volume = 2.5 L) was filled with a ring of plastic material inoculated with acclimated activated sludge. The synthetic wastewater composed of glucose, urea, KH2PO4, MgSO4, Fe2 SO4, ZnSO4 x 7H20, KCl, CaCl2, and di-sodium tetraborate decahydrate or boric acid (B = 100-2000 mg L(-1)). The biological treatment of boron containing wastewater resulted in a low treatment removal rate due to the reduced microbial activity as a result of toxic effects of high boron concentrations. The decrease in the COD removal rate by the presence of either boric acid or sodium borate was practically indistinguishable. It was observed from the experiments that about 90-95% of COD removal was possible at high COD/boron ratios.

Abstract
Urban ants are a worldwide critical household pests, and efforts to control them usually involve the use of alimentary baits containing slow-acting insecticides. A common toxicant used is boron, either as borax or boric acid. However, the presence of these compounds can affect the consumption of baits by reducing their acceptance and ingestion. Moreover, as feeding motivation varies widely, according not only to food properties but also to colony conditions, bait consumption might be diminished further in certain situations. In this study, we compared the feeding response of ants toward two boron toxic baits (boric acid and borax) in low motivation situations that enhance any possible phago-deterrence the baits may produce. Most studies investigating bait ingestion evaluate whole nests or groups of ants; here, we analyzed the individual ingestion behavior and mortality of the Argentine ant, Linepithema humile (Mayr), and the carpenter ant, Camponotus mus (Roger), for two boron baits, to detect which compound generates a higher rejection in each of these species. Although these two species have similar feeding habits, our results showed that ants under low motivation conditions reduced the acceptance and consumption of the toxic baits asymmetrically. While L. humile mostly rejected the borax, C. mus rejected the boric acid. These results denote the importance of considering the preference of each species when developing a pest management strategy.

Abstract
The acidic ionic liquid 1-H-3-methylimidazolium chloride can effectively pretreat yellow pine wood chips under mild conditions for enzymatic saccharification. Wood samples were treated at temperatures between 110 and 150°C for up to 5 h in the ionic liquid and three fractions collected; a cellulose rich fraction, lignin, and an aqueous fraction. This treatment caused the hemicellulose and the lignin to be degraded and dissolved from the cell walls of the pine wood. The lignin was depolymerized and subsequently dissolved in the ionic liquid. This process occurred more quickly at higher temperatures, although at the highest temperatures tested, significant cellulose degradation also occurred. The cellulose rich fraction was saccharified using cellulase from Trichoderma viride, with longer pretreatment times at 130°C resulting in higher glucose yields.

Current US state and federal fish health regulations target the spread of viral hemorrhagic septicemia virus-IVb (VHSV-IVb) through movement restrictions of live fish; however, they largely ignore the potential for the virus to be spread through commercial distribution and use of frozen baitfish from VHSV-IVb-positive regions. Some state laws do require treatment of frozen baitfish to inactivate VHSV, and additional methods have been proposed, but few scientific studies have examined the efficacy of these treatments. In this study, bluegills Lepomis macrochirus were challenged with VHSV-IVb and frozen to represent standard industry methods, disinfected by various treatments, and tested for infectious VHSV-IVb using virus isolation. The virus was isolated from 70% of fish subjected to 3 freeze/thaw cycles. All other treatment methods were effective in inactivating the virus, including treatment with isopropyl alcohol, mineral oil, salt and borax, and dehydration. Dehydration followed by rehydration is rapid and effective, and therefore, seems to be the best option for inactivating VHSV-IVb present in frozen baitfish while maintaining their usefulness as bait.
