Abstract
Via rational molecular structure design and using gallic acid (GA) for hydrophobic modification of cellulose nanofibers (CNF), the "polymer dipole" CNF-GA with hydrophilic main chains and hydrophobic side chains was prepared, which improved the poor piezoelectric properties of CNF used for preparing pressure sensors. Due to the appearance of the side chains, the elongation at break of the CNF-GA-2, compared with CNF, was enhanced by 186 %, and the excellent tensile strength, puncture load, and tearing strength were displayed. Moreover, the significant glass transition temperature (Tg) near the human body temperature was exhibited for CNF-GA, making it possible to be applied in temperature sensing. Most importantly, the CNF-GA-2 showed the maximum hydrophobicity, with a contact angle of 76.77°. Finally, the CNF-GA-2/MXene nanocomposite film was prepared by the CNF-GA-2 with MXene through vacuum filtration. The results indicated that the film had excellent piezoelectric properties (d33 = 63.283), the generated stable induced voltage (125.6 mV), the preferable piezoresistive performance (ΔR/R0 = 2.15), the fast response/recovery time (48/61 ms), which could achieve dynamic and static responses. Moreover, this film could be used for real-time detection of limb movements (such as wrists).

Abstract
Effective loading and delivering the wound healing-based materials to the wound site and area with an optimum concentration and limited cytotoxicity are essential for a complete and fast healing process. Here, we have designed Zn/Al-LDH nanoparticles-loaded CMC films for encapsulation and delivery of gallic acid (GA) in order to develop an effective and efficient wound-healing scaffold. The physicochemical properties of the prepared Zn/Al-LDH nanohybrids were thoroughly characterized by several characterization techniques, such as FESEM, Hi-TEM, FTIR, and XRD techniques. The thermal properties of the scaffolds were evaluated by DSC and TGA analysis. The release profiles of GA from fabricated films were studied over 8 h by UV-vis spectroscopy. In vitro drug release studies in PBS solutions with pH 7.4 showed a mono-phasic profile in which the liberation of the drug mainly occurred by scaffold erosion and increased by increasing the experiment period. The in vitro antibacterial activity of Zn/Al-LDH-GA-loaded CMC films was assessed by disk diffusion and cell viability contact tests. The results showed the desired antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. Incorporating GA within CMC and CMC-Zn/Al-LDH films rereleased good cytocompatibility at the studied incubation time and different concentrations toward human normal HFF cell line than the free drug. The results of the present study indicated that the Zn/Al-LDH and Zn/Al-LDH-GA-loaded CMC have promising wound healing features to further develop a better future for clinical remedy of the different non-healing and hard-to-heal wounds.

Abstract
In the present work, chitosan (CHT) as a biodegradable polymer was crosslinked using various amounts of glycyrrhizic acid (GLA) as a novel crosslinking agent to prepare biocompatible hydrogels. The prepared hydrogels were used for the controlled release of gallic acid (GA) in transdermal therapy application. FTIR, XRD, and SEM were used to characterize the prepared gels. The results indicated that the carboxylic acid groups of GLA react with the amine groups of the CHT in the presence of activating coupling reagents to form covalent amide linkage between the polymer chains of CHT and construct CHT cross-linked hydrogel (CCH) network structure. The prepared CCH samples were characterized and used for the controlled release of a drug, i.e. (GA). For this purpose, the swelling kinetic, loading and encapsulation efficiency, in vitro drug release, drug release kinetics, cell viability assay, and anti-bacterial activity of the samples were evaluated. The swelling ratio of CCH samples were in the range of 455-37 % depending on the pH of environment. Swelling kinetic results showed an aggregate to the non-linear second-order kinetic model. Drug release results were fitted by kinetic models while the Korsmeyer-Peppas model was fitted better. The CCH samples exhibited high biocompatibility for 5 mg/ml hydrogel concentration. In addition, the CHT and CCH sample without the GA did not show anti-bacterial properties for 1200 and 150 μg/ml concentrations, respectively. The CCH sample containing the GA exhibited enough anti-bacterial activity on the S. aureus bacteria strain at 150 μg/ml concentration. In contrast, the CCH sample containing the GA has a light anti-bacterial effect on the E. coli bacteria strain. The calculated mesh size of hydrogel networks, drug size, and kinetics models revealed that the CCH samples could release GA based on a diffusion mechanism. In conclusion, the designed CCH samples have enough ability for controlled drug release in transdermal applications.

Abstract
Vascular endothelial dysfunction plays a central role in the most dreadful human diseases, including stroke, tumor metastasis, and the coronavirus disease 2019 (COVID-19). Strong evidence suggests that angiotensin II (Ang II)-induced mitochondrial dysfunction is essential for endothelial dysfunction pathogenesis. However, the precise molecular mechanisms remain obscure. Here, polymerase-interacting protein 2 (Poldip 2) was found in the endothelial mitochondrial matrix and no effects on Poldip 2 and NADPH oxidase 4 (NOX 4) expression treated by Ang II. Interestingly, we first found that Ang II-induced NOX 4 binds with Poldip 2 was dependent on cyclophilin D (CypD). CypD knockdown (KD) significantly inhibited the binding of NOX 4 to Poldip 2, and mitochondrial ROS generation in human umbilical vein endothelial cells (HUVECs). Similar results were also found in cyclosporin A (CsA) treated HUVECs. Our previous study suggested a crosstalk between extracellular regulated protein kinase (ERK) phosphorylation and CypD expression, and gallic acid (GA) inhibited mitochondrial dysfunction in neurons depending on regulating the ERK-CypD axis. Here, we confirmed that GA inhibited Ang II-induced NOX 4 activation and mitochondrial dysfunction via ERK/CypD/NOX 4/Poldip 2 pathway, which provide novel mechanistic insight into CypD act as a key regulator of the NOX 4/Poldip 2 axis in Ang II-induced endothelial mitochondrial dysfunction and GA might be beneficial in the treatment of wide variety of diseases, such as COVID-19, which is worthy further research.

Abstract
The Oriental fruit fly, Bactrocera dorsalis (Hendel) is a major insect pest of mango fruit worldwide resulting in huge loss of fruit quality and productivity. However, there exist a few mango varieties resistant to B. dorsalis infestation. The objective of the present study was, therefore to identify the major fruit component imparting resistance to B. dorsalis. Principal Component Analysis of phenolic acids in pulp and peel tissues of two resistant varieties, viz., Langra and EC 95862, revealed that among the phenolic acids present in the fruit, gallic acid was the most abundant component in both fruit peel and pulp while laboratory studies revealed that gallic acid was acutely toxic to B. dorsalis with its dual action as antioxidant in the host and a prooxidant in the insect. Field study with the preharvest application of gallic acid on young developing fruits of B. dorsalis susceptible Alphonso mango showed that it could protect the fruit against insect damage confirming that gallic acid is essentially responsible for providing constitutive resistance against B. dorsalis in Langra and EC 95862. Thus, preharvest application of gallic acid to developing fruits could be used as part of an Integrated Pest Management strategy to control infestation by B. dorsalis. Future work on breeding / development of transgenes of susceptible mango varieties with high levels of gallic acid in fruit peel is likely to provide the simplest means of inducing constitutive resistance against B. dorsalis infestation.

Abstract
This study investigated a novel antioxidant and antimicrobial Pickering emulsion stabilized by soy protein isolate (SPI) and gallic acid (GA) as an excellent protective delivery medium for lipophilic functional food. SPI-GA complex nanoparticles were fabricated by a covalent cross-linking mechanism under alkaline conditions with a small particle size (42.93-24.91 nm) and high zeta potential (26.92-38.58 -mV), which led to improved stability at high GA concentrations. Without the addition of preservatives, it was found that SPI-GA complex nanoparticles have a certain antimicrobial ability. Using these nanoparticles as the only stabilizers, outstanding antioxidant and antimicrobial Pickering emulsions could be easily prepared, and they had a small droplet size (948.09-457.82 nm), great stability and inhibited lipid peroxidation and antibacterial ability. Oxidation and microbial protection proceeded in a GA concentration-dependent manner. This study provides a novel way to prepare functionalized Pickering emulsions as delivery media for functional lipophilic raw materials.

Abstract
The aim of this study is to determine the effect of GA on maize seedlings as well as its antioxidative effect under copper (Cu) stress. To that end, maize seedlings were exposed to 1.5 mM GA and 1 mM Cu solutions, and the seedlings were allocated to following experimental groups: 18-hr distilled water (DI) (Control), 6-hr GA + 12-hr DI (GA), 6-hr DI + 12-hr Cu (Cu), 6-hr GA + 12-hr Cu (GA + Cu), 12-hr Cu +6-hr GA (Cu + GA), and 18-hr GA and Cu mixture (GA = Cu). The experiment was designed by randomized block design with three repetitions. The results showed that GA alone and GA + Cu treatments significantly decreased membrane damage and H2O2 formation compared to the other treatments. GA formation was determined to be highest in turn in treatments GA + Cu and GA alone. The proline content significantly decreased in treatments GA alone and GA + Cu. The highest catalase (CAT) activity was observed in GA alone application, whereas GA + Cu treatment led to increase in guaiacol peroxidase (GPX), superoxide dismutase (SOD), and ascorbate peroxidase (APX) activities. GA has a protective effect on chlorophyll contents and relative water content (RWC), but not on carotenoid levels under Cu stress. Overall, GA alone application or GA + Cu stress may prevent the formation of reactive oxygen species (ROS) due to chelation effect of GA.

Abstract
BACKGROUND In this study, iron oxide nanoparticles (SPIONs) were synthesized and coated by GA (SG) and then SG was encapsulated by ICG (SGI). After identifying specifications and cytotoxicity of the agents, the potential of SGI for photodynamic therapy (PDT) and photothermal therapy (PTT) was studied. METHODS An SGI size of 12-13 nm was determined by TEM images and its zeta potential was measured at -23.8 ± 5.8 mV. MCF-7 and HT-29 cells were exposed to a non-coherent light source at a wavelength of 730 nm and a range of 3.9-124.8 J/cm2 under two different concentrations of agents. The viability of treated cells was determined via MTT assay. To analyze the effects of different irradiation conditions, some indices such as Coefficient of Light Effect, Synergism Index, Addition Ratio, Treatment Efficacy and ED50 were defined. RESULTS Cell survival at the highest power of irradiation in the absence of any agent was decreased to 93% and 73% for HT-29 and MCF-7, respectively. In both cell lines, the cellular survival dropped by increasing the light source intensity. The maximum cell death recorded for SG, ICG and SGI was 63 ± 2%, 63 ± 2% and 21 ± 2% for MCF-7 cells and 67 ± 2%, 78 ± 1% and 53 ± 1% for HT-29 cells, respectively. CONCLUSION SGI had a significant photodynamic and photothermal effect on cells. This is a promising outcome, which can help enhance the effectiveness of a minimally invasive treatment. Moreover, SPIONs can be used to apply magnetic hyperthermia or act as a contrast agent in MRI images.

Abstract
The molecularly imprinted polymers for gallic acid were synthesized by precipitation polymerization. During the process of synthesis a non-covalent approach was used for the interaction of template and monomer. In the polymerization process, gallic acid was used as a template, acrylic acid as a functional monomer, ethylene glycol dimethacrylate as a cross-linker and 2,2'-azobisisobutyronitrile as an initiator and acetonitrile as a solvent. The synthesized imprinted and non-imprinted polymer particles were characterized by using Fourier-transform infrared spectroscopy and scanning electron microscopy. The rebinding efficiency of synthesized polymer particles was evaluated by batch binding assay. The highly selective imprinted polymer for gallic acid was MIPI1 with a composition (molar ratio) of 1:4:20, template: monomer: cross-linker, respectively. The MIPI1 showed highest binding efficiency (79.50%) as compared to other imprinted and non-imprinted polymers. The highly selective imprinted polymers have successfully extracted about 80% of gallic acid from spiked urine sample.

Abstract
BACKGROUND Treatment of acute lymphoblastic leukemia (ALL) fails in some cases and the side effects cause mortality in certain patients. Gallic acid (GA), a polyhydroxyphenolic compound has biological functions including anti-proliferative properties. The aim of the present study was to investigate the growth inhibition effects of GA in combination with asparaginase (ASP), as a component of combination chemotherapy, in a lymphoblastic leukemia cell line. METHODS Jurkat cells were incubated with different concentrations of GA with or without ASP. Proliferation inhibition was investigated using MTS test. The level of apoptosis alterations were evaluated using flow cytometry. The expression of Fas gene level and surface expression were investigated by quantitative real time PCR and flow cytometry respectively. RESULTS GA at 50μM concentration and ASP at 0.5 IU/ml inhibited 50% cell proliferation in 48 hours. GA also increased the inhibitory effect of ASP and some combinations had synergistic results. The increase of cell apoptosis and Fas expression were observed in GA-treated cells compared to control. GA increased the effect of ASP on proliferation inhibition, induction of apoptosis and Fas expression. CONCLUSION GA is an effective component in proliferation inhibition, apoptosis induction and enhancement of Fas expression level in Jurkat cell line. GA in some combination with ASP increases the effect of the latter on the cells. The study of the mechanism of these effects could be a further step towards target therapy. This study is a preliminary phase to the use of GA and should be carried out by more comprehensive study and animal models.

Abstract
Cancer cells divide rapidly, providing medical targets for anticancer agents. The polyphenolic gallic acid (GA) is known to be toxic for certain cancer cells. However, the cellular mode of action has not been elucidated. Therefore, the current study addressed a potential effect of GA on the mitosis of cancer cells. GA inhibited viability of HeLa cells in a dose-dependent and time-dependent manner. We could show, using fluorescence-activated cell sorting (FACS), that this inhibition was accompanied by elevated frequency of cells arrested at the G2/M transition. This cell-cycle arrest was accompanied by mitotic catastrophe, and formation of cells with multiple nuclei. These aberrations were preceded by impaired centrosomal clustering. We arrive at a model of action, where GA inhibits the progression of the cell cycle at the G2/M phase by impairing centrosomal clustering which will stimulate mitotic catastrophe. Thus, GA has potential as compound against cervical cancer.

Abstract
Gallic acid (GA), a phenolic compound naturally present in plants, used as an antioxidant additive in food and in the pharmaceutical industry, may have cancer chemopreventive properties. In the present study, we investigated whether GA induced DNA damage and affected DNA repair-associated protein expression in human oral cancer SCC-4 cells. Flow cytometry assays were used to measure total viable cells and results indicated that GA decreased viable cells dose-dependently. The comet assay and 4',6-Diamidino-2-phenylindole dihydrochloride (DAPI) staining were used to measure DNA damage, as well as condensation and it was shown that GA induced DNA damage (comet tail) and DNA condensation in a dose-dependent manner. DNA gel electrophoresis was used to examine DNA fragmentation and we found that GA induced DNA ladder (fragmentation). Using western blotting it was shown that GA inhibited the protein expressions of MDC1, O(6)-methylguanine-DNA methyltransferase (MGMT), p-H2A.X, p53, DNA-dependent serine/threonine protein kinase (DNA-PK) and 14-3-3 proteins sigma (14-3-3σ) but increased p-p53, phosphate-ataxia-telangiectasia (p-H2A.X) and ataxia telangiectasia mutated and Rad3-related (p-ATR), phosphate-ataxia telangiectasia mutated (p-ATM) and breast cancer susceptibility protein 1 (BRCA1) in a 24-h treatment. The protein translocation was examined by confocal laser microscopy and results indicated that GA increased the levels of p-H2A.X, MDC1 and p-p53 in SCC-4 cells. In conclusion, we found that GA-induced cell death may proceed through the induced DNA damage and suppressed DNA repair-associated protein expression in SCC-4 cells.
