Abstract
INTRODUCTION Scarring after burn injuries remains one of the major challenges in burn medicine and is the subject of current research. Accurate and high-quality assessment of scars is needed to enable exact outcome evaluation of different treatments. Our aim was to evaluate the most common subjective scar evaluation scores-the POSAS (Patient and Observer Scar Assessment Scale) and VSS (Vancouver Scar Scale)-in comparison with the objective device Mexameter® for colour evaluation. METHODS A prospective monocentre study was performed, which included 120 examined scar areas of 60 patients with third degree burns who had received skin grafts between 1975 and 2018 with a total burned surface area (TBSA) > 2%. Two different scar areas in comparison with one healthy skin area concerning 'colour', 'pigmentation', and 'vascularization' were evaluated by the Mexameter® MX 18, the OSAS, and the VSS by the same examiner, as well as the PSAS by the patient. RESULTS The mean TBSA of the 60 patients was 24.3%. In the OSAS, 61% of the scars were evaluated as 'hyper-', 19% as 'hypo-', and 19% as 'mix-pigmented'. Furthermore, 65% of the scars were estimated as highly vascularized. In the Mexameter®, the melanin index values of the scar areas compared to the healthy skin areas showed a small difference of 12 (p < 0.05). The mean difference of erythema between the scar and the healthy skin areas was 84 (p < 0.001). For the Mexameter®, moderate correlations were found when comparing 'erythema' with the OSAS category 'vascularization' (r = 0.33, p < 0.05) and 'melanin' with the OSAS parameter 'pigmentation' (r = 0.28, p < 0.05). When comparing the Mexameter® measurements to the OSAS questionnaire, 27% of the scars were wrongly evaluated as 'hyperpigmented' by the observer and 21% as 'hypervascularized', while showing low measurements in the device. Additionally, a novel Mexameter® ordinal scare scale was calculated. CONCLUSION In this study, we were able to show on a relatively large patient population that with the Mexameter®, the subjectivity of the scar colour assessment by examiner/patient can be overcome, but precise differentiation can still be ensured with subjective evaluation tools. We further introduced a novel Mexameter® Scar Scale. It is necessary to further investigate the vast range of objective devices and develop scar panels for with an incorporation of objective and subjective devices to further improve reliability with reduced bias in terms of scar assessment.

Abstract
Hydrothermal carbonization (HTC) can mitigate the disposal costs of sewage sludge in a wastewater treatment plant. This study analyzes the impact of integrating HTC with anaerobic digestion (AD) and combustion from a combined energy and economic performance perspective. Net energy balance and investment opportunity are investigated for a number of technical scenarios considering i) different combinations of the technologies: AD + HTC, AD + thermal dryer + combustion, and AD + HTC + combustion, ii) different options for HTC process water treatment: wet oxidation (WO) + AD, and direct return to AD, and iii) different products: heat-only, heat and electricity, hydrochar, and phosphorus. The results show trade-offs between investment cost, self-supplement of heat, and output electricity when WO is used. In AD + HTC, net heat output decreases compared to the reference plant, but avoided disposal costs and hydrochar revenue result in profitable investment when the process water is directly returned to the AD. Although HTC has a lower heat demand than the thermal dryer, replacing the thermal dryer with HTC is only possible when AD, HTC, and combustion are connected, or when WO covers HTC's heat demand. HTC may impair the electricity production because of the necessity for a high-temperature heat source, whereas the thermal dryer can utilize a low-temperature heat source. In conclusion, energy advantages of HTC in AD + HTC + combustion are insufficient to provide a promising investment opportunity due to high investment costs of HTC. The investment opportunity improves by co-combustion of hydrochar and external sludge.

Abstract
Since pebrine disease, as the most important and dangerous disease in silkworms, spreads horizontally through the spores and vertically through the eggs, combating the disease and eliminating it completely from livestock production has been associated with numerous problems. This project aimed to identify the molecular cause of pebrine disease in silkworms using a sensitive, specific, and accurate method. To this purpose, a 136 bp fragment was selected based on the Nosema bombycis partial SSU rDNA sequence, and a pair of primers was designed. Afterward, using the conventional polymerase chain reaction (PCR) method, the target fragment was amplified and sequenced. After that, to determine the detection sensitivity, using the Real-Time PCR method, 5-fold serial dilutions of N. bombycis DNA were prepared, and the last dilution that produced a fluorescent signal was considered the minimum detection limit. All tests were performed in duplicates. Based on the results of the sensitivity test, the standard curve including Ct values and DNA concentration was used for analysis. Moreover, 80 unknown samples examined by light microscope were evaluated using conventional PCR and Real-Time PCR. Both PCR results showed no amplification for the negative control samples. The findings demonstrated that the lowest detection limit for N. bombycis was less than 6 pg of DNA, while, this amount was 8 ng for conventional PCR. Out of 80 samples examined, 55, 60, and 62 samples were positive for light microscope, conventional PCR, and Real-Time PCR methods, respectively. The findings suggested that the Real-Time PCR method had a higher ability to detect the causative agent of pebrine disease than the conventional PCR method, and both methods were superior to light microscopy. Therefore, due to the fewer steps and higher accuracy of Real-Time PCR, it can be introduced as a suitable method for diagnosing pebrine disease.

Abstract
BACKGROUND Burn injuries constitute the fourth most common injuries globally. Patient outcomes must be currently assessed to provide appropriate patient care with high quality standards. However, existing mortality prediction scoring methods have been shown to lack accuracy in current burn patient populations. Therefore, this study aimed to validate existing scores using current patient data and assess whether new prediction parameters can provide better accuracy. METHODS A retrospective analysis of the patient data from the German Burn Registry between 2016 and 2019 was performed to evaluate all Abbreviated Burn Severity Index (ABSI) score parameters. All patients over 16 years of age who received intensive care were included. Descriptive statistics and logistic regression analysis were used to identify novel prediction parameters based on the parameters documented at admission and establish a new prediction score, the BUrn Mortality Prediction (BUMP) score. The quality of the new score was subsequently compared to that of the original ABSI, modified ABSI, Galeiras, Revised Baux score and TIMM. The new prediction score was then validated using patient data collected in the German Burn Registry in 2020. RESULTS In total, 7276 patients were included. Age; the presence of at least two comorbidities; burn injuries caused by work-related accidents, traffic accidents and suicide attempts; total burn surface area; inhalation trauma and full-thickness burns were identified as independent significant predictors of mortality (p < 0.001). Additionally, we evaluated new age groups to improve prediction accuracy. The number of comorbidities (p < 0.001) and the aetiology (burns occurring at work [p = 0.028], burns caused by traffic accidents [p < 0.001] or burns due to attempted suicide [p < 0.001]) had a significant influence on mortality. The BUMP score, which was developed based on these parameters, showed the best fitness and showed more accurate mortality prediction than all the above-mentioned scores (area under the receiver operating characteristic curve: 0.947 [0.939-0.954] compared to 0.926 [0.915-0.936], 0.928 [0.918-0.939], 0.937 [0.928-0.947], 0.939 [0.930-0.948], 0.940 [0.932-0.949] respectively). CONCLUSIONS A novel score (BUMP score) was developed for the purpose of external quality assessment of burn centres participating in the German burn registry, where observed and expected outcomes are compared on a hospital level, and for scientifically applications. The clinical impact of this score and its generalisability to other patient populations needs to be evaluated.

Abstract
Sewage sludge management is torn between a desire for pollution prevention and reuse of a valuable resource. Reconciling these interests in sustainable management is a challenge for researchers. This study focuses on how research on sewage sludge management practices has evolved and scrutinizes how this research is interlinked with concerns and societal issues such as contaminants, economic efficiency, and legislation. Based on published academic papers on sewage sludge management between 1971 and 2019, this study found four trends in research focused on sewage sludge management: a decreasing interest in disposal (landfilling and sea dumping), a dominant interest in land application, a growing interest in sewage sludge as product, and a stable interest in energy recovery. Research on disposal focuses on increasing sludge volumes, legislative changes, and economic challenges with an interest in waste co-treatment. Research on land application concerns nutrient use and contaminants, mainly heavy metals. Research on sewage sludge as a product focuses on the extraction of certain resources and less on use of sewage sludge specifically. Research on energy recovery of sewage sludge focuses on volume reduction rather than contaminants. Two-thirds of the papers are detailed studies aiming to improve single technologies and assessing single risks or benefits. As management of sewage sludge is multifaceted, the narrow focus resulting from detailed studies promotes some concerns while excluding others. Therefore, this study highlights potential gaps such as the combination of nutrient use and disposal and energy recovery and nutrient use.

Abstract
Pebrine disease is the most important and dangerous disease of silkworm caused by Nosema bombycis as an obligate intracellular parasitic fungus. It has caused tremendous economic losses in the silk industry in recent years. Given the fact that light microscopy method (with low accuracy) is the only method for diagnosing pebrine disease in the country, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) methods were adopted in this study for accurate morphological identification of the spores causing pebrine disease. Infected larvae and mother moth samples were collected from several farms (Parand, Parnian, Shaft, and Iran Silk Research Center in Gilan province, Iran). The spores were then purified using the sucrose gradient method. From each region, 20 and 10 samples were prepared for SEM and TEM analysis, respectively. In addition, an experiment was performed to evaluate the symptoms of pebrine disease by treating fourth instars with the spores purified for the present study, along with a control group. The results of SEM analysis showed that the mean±SD length and width of spores were 1.99±0.25 to 2.81±0.32 μm, respectively. Based on the obtained results, the size of spores was smaller than the Nosema bombycis (N. bombycis) as the classic species that cause pebrine disease. In addition, transmission electron microscopy (TEM) pictures showed that the grooves of the adult spores were deeper than those of other Nosema species, Vairomorpha, and Pleistophora, and resembled N. bombycis in other studies. Examination of pathogenicity of the studied spores indicated that the disease symptoms in controlled conditions were similar to those in the sampled farms. The most important symptom in fourth and fifth instrars were the small size and no growth in the treatment group compared with the control group. Findings of SEM and TEM analysis showed better morphological and structural details of parasite compared with light microscopy, and demonstrated that the studied species were a native strain of N. bombycis specific to Iran, whose size and other characteristics were unique and introduced for the first time in this study.

Abstract
Removal efficiency of gold from a solution of pure tetrachloroaurate ions was investigated using microbial fuel cell (MFC) technology. The effects of type of catholyte solution and initial gold concentration on the removal efficiency were considered. Due to its presence at high levels in the gold wastewater, the effect of copper ions on the removal efficiency of the gold ions was also studied. The effects of pH and initial biomass concentration on the gold removal efficiency was also determined. The results showed that after 5 h contact time, 95% of gold removal efficiency from a wastewater containing 250 ppm of initial gold ions at ambient temperature using 80 g/L yeast concentration was achieved. After 48 h of the cell's operation under the same condition, 98.86% of AuCl4– ions were successfully removed from the solution. At initial gold concentration in the waste solution of 250 ppm, pH 2, and initial yeast concentration of 80 g/L, 100% removal efficiency of the gold was achieved. On the other hand, the most suitable condition for copper removal was found at a pH of 5.2, where 53% removal efficiency from the waste solution was accomplished.

Abstract
American foulbrood (AFB) and European foulbrood (EFB) are the two most important honey bee brood diseases which impose heavy economic losses to the apiculture industry worldwide by reducing bee population and honey production. Treatment with antibiotics has led to the emergence of antibiotic-resistant strains, calling for alternative safe treatment procedures that could control these diseases. Honey bee gut microbiota is known to affect the overall health of honey bees by enhancing their resistance to a number of diseases via modulation of the immune response and production of different antimicrobial metabolites. The majority of these gut resident bacteria are identified as probiotic bacteria and secure the health of these tiny insects. In the present review, we highlighted the significance of the honey bee gut microbial community and their probiotic potency for the prevention of AFB and EFB diseases in honey bees.

Abstract
The novel quaternary CNT/TiO2/WO3/CdS nanostructure was fabricated to be employed in the photocatalytic degradation of reactive blue 19 (RB19) under the visible light irradiation. The physicochemical properties of the pure TiO2, CNT/TiO2, CNT/TiO2/WO3, and CNT/TiO2/WO3/CdS were characterized using XRD, FTIR, FESEM, EDX, DRS, PL, and BET analyses. The photodegradation results showed that the optimum weight percentage of CNT, WO3, and CdS was 4%, 35%, and 5%, respectively. The highest RB19 degradation efficiency of CNT/TiO2/WO3/CdS was achieved 97%. Besides, the central composite design was applied to model and optimize the photocatalytic activity of CNT/TiO2/WO3/CdS nanocatalyst and assess the effects of processing variables including RB19 concentration, catalyst concentration, pH, and irradiation time on the response. RB19 concentration and pH had the most and the second most significant role in the removal efficiency. While increasing the catalyst concentration and irradiation time positively enhanced the removal efficiency to more than 82%, increasing the pH and dye concentration showed the remarkable hindering effects on the removal efficiency by about 45% reduction. The reusability of the synthesized catalysts was studied under the optimum conditions as follows: [RB19] = 25 mg/L, [catalyst] = 1 g/L, pH of 4, and irradiation time = 2 h. The COD and TOC analyses were also conducted during photodegradation process. The COD and TOC removal efficiencies were achieved about 67% and 62%, respectively.

Abstract
Lattice Monte Carlo (LMC) simulations are widely used to investigate diffusion-controlled problems such as drug-release systems. The presence of an inhomogeneous diffusivity environment raises subtle questions about the interpretation of stochastic dynamics in the overdamped limit, an issue sometimes referred to as the "Ito-Stratonovich-isothermal dilemma." We propose a LMC formalism that includes the different stochastic interpretations in order to model the diffusion of particles in a space-dependent diffusivity landscape. Using as an example a simple inhomogeneous one-dimensional system with a diffusivity interface and different boundary conditions, we demonstrate that we can properly reproduce the steady state and dynamic properties of these systems and that these properties do depend on the choice of calculus. In particular, we argue that the version of the LMC algorithm that uses Ito calculus, which is commonly used to model drug delivery systems, should be replaced by the isothermal version for most applications. Our LMC methodology provides an efficient alternative to Langevin simulations for a wide class of space-dependent diffusion problems.

Abstract
BACKGROUND Due to the further decrease in the number of habilitations in medicine since 2010, the general requirements for habilitation could have increased during the same period. OBJECTIVE The requirements for a medical habilitation at German universities in a comparison of 23 years are re-evaluated. MATERIAL AND METHODS An analysis of habilitation regulations for 12 target parameters and evaluation of these by a scoring system (range 0-34 points). RESULTS Only the criterion of the requirement for a doctorate has remained the same in the 23-year comparison in the evaluation (1998-2021). All results of the other 11 criteria have changed compared to the previous study from 2010. The rating of habilitation achievements has increased from a total score in 1998 of 15.2 ± 5.1 points (95% confidence interval 13.6-16.9 points) to 25.1 ± 3.6 points in 2021 (95% confidence interval 23.9-26.2 points; p < 0.001). The range of assigned scoring values is again more broadly spread in the 11-year comparison with values from 12 to 31 points. A striking new criterion was that 98% of the assessed habilitation regulations now require a didactic continuing education in, however, significantly different requirements from the faculties. CONCLUSION The requirements for a medical habilitation continued to significantly increase over the 23-year period with, however, a wider dispersion of scores. The more detailed description can be seen as a direct indication of an improvement in transparency. In contrast, the broader dispersion shows that a uniform assessment standard for Germany has again receded into the distance.

Abstract
Throughout 2020 and beyond, the entire world has observed a continuous increase in the infectious spread of the novel coronavirus (SARS-CoV-2) otherwise known as COVID-19. The high transmission of this airborne virus has raised countless concerns regarding safety measures employed in the working conditions for medical professionals. Specifically, those who perform treatment procedures on patients which intrinsically create mists of fine airborne droplets, i.e., perfect vectors for this and other viruses to spread. The present study focuses on understanding the splatter produced due to a common dentistry technique to remove plaque buildup on teeth. This technique uses a high-speed dentistry instrument, e.g., a Cavitron ultrasonic scaler, to scrape along the surface of a patient's teeth. This detailed understanding of the velocity and the trajectory of the droplets generated by the splatter will aid in the development of hygiene mechanisms to guarantee the safety of those performing these procedures and people in clinics or hospitals. Optical flow tracking velocimetry (OFTV) method was employed to obtain droplet velocity and trajectory in a two-dimensional plane. Multiple data collection planes were taken in different orientations around a model of adult mandibular teeth. This technique provided pseudo-three-dimensional velocity information for the droplets within the splatter developed from this high-speed dental instrument. These results indicated that within the three-dimensional splatter produced there were high velocities (1-2 m/s) observed directly below the intersection point between the front teeth and the scaler. The splatter formed a cone-shape structure that propagated 10-15 mm away from the location of the scaler tip. From the droplet trajectories, it was observed that high velocity isolated droplets propagate away from the bulk of the splatter. It is these droplets which are concerning for health safety to those performing the medical procedures. Using a shadowgraphy technique, we further characterize the individual droplets' size and their individual velocity. We then compare these results to previously published distributions. The obtained data can be used as a first step to further examine flow and transport of droplets in clinics/dental offices.

Abstract
A transportation problem basically deals with the problem which aims to minimize the total transportation cost or maximize the total transportation profit of distributing a product from a number of sources or origins to a number of destinations. While, in general, most of the real life applications are modeled as a transportation problem (TP) with the multiple, conflicting and incommensurate objective functions. On the other hand, for some reason such as shortage of information, insufficient data or lack of evidence, the data of the mentioned problem are not always exact but can be fuzzy. This type of problem is called fuzzy multi-objective transportation problem (FMOTP). There are a few approaches to solve the FMOTPs. In this paper, a new fuzzy DEA based approach is developed to solve the Fully Fuzzy MOTPs (FFMOTPs) in which, in addition to parameters of the MOTPs, all of the variables are considered fuzzy. This approach considers each arc in a FFMOTP as a decision making unit which produces multiple fuzzy outputs using the multiple fuzzy inputs. Then, by using the concept of the common set of weights (CSW) in DEA, a unique fuzzy relative efficiency is defined for each arc. In the following, the unique fuzzy relative efficiency is considered as the only attribute for the arcs. In this way, a single objective fully fuzzy TP (FFTP) is obtained that can be solved using the existing standard algorithms for solving this kind of TPs. A numerical example is provided to illustrate the developed approach.

Abstract
There was evaluation of effects of biotin administration on oviductal abundance of transforming growth factor-β (TGF-β) and carbonic anhydrase (CA) mRNA transcript in younger and older broiler hens of relatively lesser and greater fertility lines. Additionally, effects of biotin supplementation on attenuation of age-related subfertility were evaluated. Hens from the relatively greater (Line D, n = 60) and lesser (Line B, n = 60) fertility rate line were randomly assigned to three treatment groups. Biotin was not or was administered in drinking water from 30 to 33 (younger age) and 53 to 56 (older age) wk of age to have access to no biotin (T0), or 0.3 (T1), or 0.45 (T2) mg/L of biotin. There was assessment the relative oviductal abundances of TGF-β and CA mRNA transcript abundances. Supplemental biotin and age had no effect on the relative abundance of oviductal TGF-β mRNA transcript in hens of Line D. There, however, was a ten-fold greater abundance of TGF-β in hens of the T0 group of Line B compared with Line D. Relative abundance of TGF-β mRNA transcript was greater in younger hens of Line B; however, biotin supplementation of older hens of the T2 group of Line B resulted in a similar TGF-β abundance to that of younger hens. Inconstant with the TGF-β abundance, CA abundance in hens of Line B was not affected by supplemental biotin or bird age. Overall, differences in TGF-β or CA abundances did not affect fertility of broiler hens.

Abstract
OBJECTIVE Trichophyton verrucosum is a slow growing dermatophyte responsible for a number of skin diseases such as ringworm, and is characterized by patches of hair loss and thick crusts on the host skin in domestic animals. In this study, we examined the immunomodulatory effects of crude extract of Trichophyton verrucosum (TV)cytoplasm in a mouse model. METHODS The TV variate was cultured on Sabouraud dextrose agar and the mycelium was grinded by mechanical force. The purified protein was obtained from crude extract of the fungus, and protein concentration was measured by BradFord assay. Six to eight week-female BALB/c mice were divided into three groups: test group, receiving cytoplasmic crude extract plus defibrinated sheep blood; control group, receiving defibrinated sheep blood; and normal group, receiving normal saline. Injections were performed on days 0, 3, 5, 7 and 9 and the mice were sacrificed four days after the last injection. T lymphocyte metabolic activity was examined by methyl thiazol tetrazolium (MTT) assay, and also interleukin-4 (IL-4) and interferon-γ (IFNγ) levels were evaluated by enzyme-linked immunosorbent assay (ELISA). RESULTS MTT assay showed that the TV extract stimulated lymphocyte metabolic activity. ELISA results showed that despite increase in the level of IFNγ, no changes were observed in IL-4 level. CONCLUSIONS Results indicated that crude extract of TV cytoplasm may probably act as an immune modulator, which affects Th1 responses. The TV crude extract may be an appropriate agent to induce cellular immunity for combating dermatophytosis infection in animals; and therefore, TV extract may have some potential applications in vaccine/adjuvant technology.

Abstract
According to global data, intimate partner violence and its corresponding impact threaten the lives of almost 35% of women at some point in their life. The aim of this research was to explore the effects of intimate partner sexual violence on women's sense of self-efficacy when it comes to speaking out against violence and seeking help. In-depth interviews and a thematic analysis approach were employed to collect and analyze the data. The participants were 10 women with experiences of intimate partner sexual violence. They were selected through purposive and snowball sampling. Two main themes were drawn from the data, including Exposure and Empowerment. Exposure refers to the type of violence women have experienced and its physical and emotional effects; and Empowerment refers to factors women considered as giving them the courage to speak out against perpetrators, to seek help from others, or to refrain from doing either. It is concluded that Iranian women are not passive when exposed to intimate partner sexual violence, and social support, mainly from family and friends, was a pathway to feelings of empowerment; without this support, women's emotional health is put in jeopardy. Due to the importance of social networks in creating a sense of empowerment, it is recommended that professionals involved in cases of intimate partner sexual violence create an alliance with the women's families and friend and educate them on how to prevent violence or offer help before the violence takes its toll on woman's emotional and physical wellbeing.

Abstract
Polymyxin B and E (colistin), are a group of cationic charged cyclic antibiotic lipopeptides that are frequently used in the clinics to treat infections caused by the multidrug-resistant gram-negative bacteria. Since the interactions with the blood plasma drug-transport proteins may play a critical role in determining their pharmacological and pharmacokinetic profiles, we studied the binding properties of polymyxins to the human serum albumin (HSA) under simulated physiological conditions by the combination of biophysical approaches, such as isothermal titration calorimetry (ITC), fluorescence anisotropy, circular dichroism (CD) buttressed by computational studies. The HSA binding to the polymyxins was relatively strong (Ka ≈ 1.0 × 107 M-1). Molecular docking indicated that polymyxins bind to the cleft of HSA between domains I and III via the electrostatic interactions. This evidence was further confirmed by the entropy-driven interaction for the polymyxins bound HSA. Far UV-CD experiments showed that the secondary structure of HSA doesn't alter and its stable structure is preserved. Collectively, these investigations revealed that the polymyxins bind preferentially to the partially unfolded intermediate forms of the protein structure; however, HSA molecule does not undergo any significant conformational changes upon binding. This is promising as it may limit the unfavorable side effects of the medicine. On the whole, the results provide quantitative and qualitative insight of the binding interaction between HSA and polymyxins, which is important in understanding their effect as therapeutic agents.

Abstract
OBJECTIVES Present investigation was carried out to evaluate the mRNA level of TNF receptor type 1 (TNFR1) and TNF receptor type 2 (TNFR2) in peripheral-blood cells in patients with premature CAD over healthy controls. BACKGROUND TNFα as a pleiotropic cytokine could be concerned in cardiovascular pathophysiology regarding its special effects on endothelial cells. TNFα exerts its activities through its receptors, TNFR1 and TNFR2. METHODS Totally, 40 patients with premature CAD and 40 healthy controls were studied. The qRT-PCR technique was used to determine the mRNA level of TNFR1 and TNFR2 in tested groups. RESULTS The results of this study show that the relative expression was 1.32 ± 0.34 in cases and 1.11 ± 0.16 in controls for TNFR1. The relative expression was 0.96 ± 0.13 in cases and 1.49 ± 0.41 in controls for TNFR2. There is no significant difference in the level of gene expression in the studied groups regarding TNFR1 and TNFR2 genes (p > 0.05). CONCLUSION It can be concluded that the mRNA levels of TNFR1 and TNFR2 were not associated with CAD risk. Studies with more details, larger sample size, and new risk loci are necessary to reveal disease-causing mechanisms in the pathogenesis of CAD (Fig. 3, Ref. 21).

Abstract
Parkinson's disease (PD), which is the second most common neurodegenerative disorder after Alzheimer's disease, is firstly defined after James Parkinson's report. It carries motor symptoms such as resting tremor, bradykinesia and rigidity of skeletal muscle and freezing of gait. Furthermore, non-motor symptoms such as cognitive and behavioral problems, besides sensory impairments are seen in the patients. However, they may also suffer from sleep disorders or autonomic dysfunction. Although there are some medications in order to symptomatic management, but unfortunately, scientist could not have found exact approaches to cure this disease. Hence, producing a model which can express the most pathophysiologic and behavioral aspects of the disease is a desire. In this paper, we aimed to describe the different models of Parkinson's disease in brief.

Abstract
Objective: Acute erythroleukemia (AEL) is a subtype of acute myeloid leukemia (AML), with no specific treatment. Up- or downregulation of long noncoding RNAs (lncRNAs) is strongly associated with the formation and progression of many malignancies. Plasmacytoma variant translocation 1 (PVT1) is a significantly upregulated lncRNA in AML. Antisense locked nucleic acid (LNA) GapmeRs oligonucleotides are the novel tools for targeting lncRNAs. The purpose of the current study was to investigate the functional role of PVT1 antisense LNA GapmeRs on AEL cell line (KG-1). Materials and Methods: AEL cells were transfected with PVT1 antisense LNA GapmeRs at three different time points. Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) was accomplished to evaluate the PVT1 expression by PVT1 antisense LNA GapmeRs. The viability was evaluated by MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyl tetrazolium bromide) assay, and the apoptosis and necrosis were assessed by Annexin V/propidium iodide staining assay. The C-MYC expression level, the target gene of PVT1, was also quantified by qRT-PCR. Results: The results indicated that PVT1 inhibition could significantly decrease the viability of AEL cells, due to induction of apoptosis and necrosis, probably through the downregulation of C-MYC. Conclusions: Their findings suggest that the inhibition of lncRNA PVT1 could serve as a novel approach for controlling the proliferation of AEL cells and could open up a path for treatment of AEL.

Abstract
BACKGROUND AND PURPOSE Photon-counting detectors offer the potential for improved image quality for brain CT but have not yet been evaluated in vivo. The purpose of this study was to compare photon-counting detector CT with conventional energy-integrating detector CT for human brains. MATERIALS AND METHODS Radiation dose-matched energy-integrating detector and photon-counting detector head CT scans were acquired with standardized protocols (tube voltage/current, 120 kV(peak)/370 mAs) in both an anthropomorphic head phantom and 21 human asymptomatic volunteers (mean age, 58.9 ± 8.5 years). Photon-counting detector thresholds were 22 and 52 keV (low-energy bin, 22-52 keV; high-energy bin, 52-120 keV). Image noise, gray matter, and white matter signal-to-noise ratios and GM-WM contrast and contrast-to-noise ratios were measured. Image quality was scored by 2 neuroradiologists blinded to the CT detector type. Reproducibility was assessed with the intraclass correlation coefficient. Energy-integrating detector and photon-counting detector CT images were compared using a paired t test and the Wilcoxon signed rank test. RESULTS Photon-counting detector CT images received higher reader scores for GM-WM differentiation with lower image noise (all P < .001). Intrareader and interreader reproducibility was excellent (intraclass correlation coefficient, ≥0.86 and 0.79, respectively). Quantitative analysis showed 12.8%-20.6% less image noise for photon-counting detector CT. The SNR of photon-counting detector CT was 19.0%-20.0% higher than of energy-integrating detector CT for GM and WM. The contrast-to-noise ratio of photon-counting detector CT was 15.7% higher for GM-WM contrast and 33.3% higher for GM-WM contrast-to-noise ratio. CONCLUSIONS Photon-counting detector brain CT scans demonstrated greater gray-white matter contrast compared with conventional CT. This was due to both higher soft-tissue contrast and lower image noise for photon-counting CT.

Abstract
PURPOSE Polycystic ovary syndrome (PCOS) affects quality of life and can worsen anxiety and depression either due to the features of PCOS or due to the diagnosis of a chronic disease. Corticotrophin-releasing hormone (CRH) and nerves growth factor (NGF) are the modulator for the actions of the sympathetic nervous and immune systems. METHODS In total, 171 women divided into two groups: study and control groups. Serum CRH, NGF, and interleukins: IL-1α. IL-1β, 17A, and TNFα were determined by ELISA Kits in both groups. RESULTS The results showed that IL-1α (p < 0.001) and β (p = 0.017) significantly increased in PCO group. CRH, NGF, and IL-17α in serum of patients with PCO significantly lower than the control group (p < 0.001). The results of this study indicate: (1) destruction of three cytokines pattern, (2) Reduction of CRH, NGF, and IL-17α in serum of PCO patients can be under the direct influence of the sympathetic nervous system (SAS), and (3) reduction of CRH and NGFα can be reason of psych/emotional distress in women with PCOS. CONCLUSIONS The results of this study confirm (1) low-grade chronic inflammation in PCOS. This impaired cytokine pattern can play a major role in the immune-pathogenesis of PCOS; (2) hyponeurotrophinemia and reduction of CRH in women with PCOS could reflect deficit of neuronal stress-adaptation in these patients.

Abstract
Background: Features of malignant melanoma (MM) vary in the different geographic regions of the world. This may be attributable to environmental, ethnic, and genetic factors. The aim of this study was to determine the expression of estrogen receptor alpha (ER-α) in MM in Isfahan, Iran. Materials and Methods: This study was planned as a descriptive, analytical, cross-sectional investigation. During this study, paraffin-embedded tissue blocks of patients with a histopathologic diagnosis of MM was studied for ER-α using immunohistochemistry (IHC). Results: In this study, 38 patients (female/male; 20/18) with a definite diagnosis of malignant cutaneous melanoma and mean age of 52.4 ± 11.2 years were investigated. Using envision IHC staining, there were not any cases with ER-α expression. Conclusion: In confirmation to the most previous studies, expression of ER-α was negative in MM. It is recommended to investigate the expression of estrogen receptor beta and other markers in MM.

Abstract
Formaldehyde removal from an air stream absorbed into a water stream in a packed bed continuously and then removed by employing a combination of UV and ferrate(VI) as a highly-powerful oxidant in a continuous stirred tank. In addition, the removal of formaldehyde from water was investigated in both batch and continuous modes. The results of the study performed on formaldehyde-contaminated water treatment can be used for both air and water treatment process design. The primary objective of this study is to compare the performance of using UV and ferrate(VI) individually with that of using UV/ferrate(VI) simultaneously to remove formaldehyde from both air and water. Moreover, the effects of several factors such as pH, ferrate(VI) concentration and temperature on formaldehyde removal from water using ferrate(VI) method were evaluated. The results of the current study in batch condition showed that the best initial pH and ferrate(VI) concentration to obtain the highest formaldehyde removal are 2 and 1 mg/l, respectively. The results of this part of research also reveal that temperatures rise from 25 °C to 50 °C increases formaldehyde removal from 69% to 97%; however, further increase in temperature has an adverse effect on removal efficiency. The combination of UV and ferrate(VI) enhances formaldehyde removal efficiency to very close to 100% within 35 min. In continuous air stream treatment, maximum formaldehyde removal of 94% was obtained by using a packed bed scrubber with gas over liquid flow rates ratio of 1.28 m3/m3. Although the results of this study shows that ferrate(VI) method for removal of formaldehyde can be considered as a promising alternative for both water and air treatment, further economic studies are required for this process to be commercialized.

Abstract
Tumour-draining lymph nodes (TDLNs) are centre in orchestrating the immune responses against cancer. The cellularity and lymphocyte subpopulations change in the process of cancer progression and lymph node involvement. B lymphocyte subsets and their function in breast cancer-draining lymph nodes have not been well elucidated. Here, we studied the influence of tumour metastasis on the frequencies of different B cell subsets including naïve and memory B cells as well as those which are known to be enriched in the regulatory pool in TDLNs of 30 patients with breast cancer. Lymphocytes were obtained from a fresh piece of each lymph node and stained for CD19 and other B cell-associated markers and subjected to flow cytometry. Our investigation revealed that metastatic TDLN showed a significant decrease in active, memory and class-switched B cells while the frequencies of B cells with regulatory phenotypes were not changed. However, CD27(hi) CD25(+) and CD1d(hi) CD5(+) B regulatory subsets significantly increased in non-metastatic lymph nodes (nMLNs) of node-positive patients compared with node-negative patients. Our data provided evidence that in breast cancer, metastasis of tumour to axillary lymph nodes altered B cell populations in favour of resting, inactive and unswitched phenotypes. We assume that the lymphatic involvement may cause an increase in a subset of regulatory B cells in non-metastatic lymph nodes.

Abstract
In this paper, we investigate the impact of longitudinal dispersion fluctuations of the optical fiber on the gain spectrum and the saturation behavior of one-pump fiber-optical parametric amplifiers (1-P FOPAs). The gain spectra and the saturation curves of 1-P FOPAs are simulated by solving the coupled amplitude equations numerically and taking into account the dispersion fluctuations as a stochastic process with a given standard deviation and correlation length. Results show that the shape and the level of the gain spectrum and also the saturation power of 1-P FOPAs are considerably changed in the presence of dispersion fluctuations in comparison with the case when dispersion fluctuations are ignored. This feature is also totally different compared with the small-signal gain spectrum of the FOPA in the presence of dispersion fluctuations. Moreover, the value of the change in the gain and the saturation power depends strongly on the fluctuation parameters, i.e., the standard deviation and the correlation length.

Abstract
Odorous gases are the most important reason that people register complaints with organizations responsible for wastewater collection and treatment systems (WCTS). Although several studies have been conducted for prevention and control of odorous gases, no comprehensive research exists about recent achievements in this area. The aim of the present study is to collect and categorize the new achievements in preventing and controlling odorous gases in WCTS. Two strategies for controlling odor emissions from WCTS are (1) prevention of odor production and (2) removal of odorous compounds from emissions of WCTS. Between the two, priority goes to preventing odorous compounds' production. Several methods have been developed to prevent odor production, such as increasing oxidation reduction potential; inhibiting the activity of sulfide reducing bacteria; chemical removal of hydrogen sulfide; applying formaldehyde and paraformaldehyde to prevent hydrogen sulfide production; and using fuel cells in hydrogen sulfide inhibition and gradual release of oxygen in gas phase by using MgO2 or CaO2. In addition to preventing odorous compounds in WCTS, many other methods have been introduced to remove odorous compounds from emissions of WCTS, such as biofilters; bioscrubbers; biotrickling filters; suspended growth reactors; and membrane bioreactors and scrubbers. Through this review, responsible organizations can find new, effective, and economical strategies to prevent and control odorous gases in WCTS.

Abstract
The obesity paradox is often attributed to fat acting as a buffer to protect individuals in fragile metabolic states. If this was the case, one would predict that the reverse epidemiology would be apparent across all causes of mortality including that of the particular disease state. We performed a dose-response meta-analysis to assess the impact of body mass index (BMI) on all-cause and stroke-specific mortality among stroke patients. Data from relevant studies were identified by systematically searching PubMed, OVID and Scopus databases and were analysed using a random-effects dose-response model. Eight cohort studies on all-cause mortality (with 20,807 deaths of 95,651 stroke patients) and nine studies of mortality exclusively because of stroke (with 8,087 deaths of 28,6270 patients) were evaluated in the meta-analysis. Non-linear associations of BMI with all-cause mortality (P < 0.0001) and mortality by stroke (P = 0.05) were observed. Among overweight and obese stroke patients, the risk of all-cause mortality increased, while the risk of mortality by stroke declined, with an increase in BMI. Increasing BMI had opposite effects on all-cause mortality and stroke-specific mortality in stroke patients. Further investigations are needed to examine how mortality by stroke is influenced by a more accurate indicator of obesity than BMI.

Abstract
The performance of an energy conversion system depends on exergy analysis and entropy generation minimisation. A new simple four-parameter equation is presented in this paper to predict the standard state absolute entropy of real gases (SSTD). The model development and validation were accomplished using the Linear Genetic Programming (LGP) method and a comprehensive dataset of 1727 widely used materials. The proposed model was compared with the results obtained using a three-layer feed forward neural network model (FFNN model). The root-mean-square error (RMSE) and the coefficient of determination (r(2)) of all data obtained for the LGP model were 52.24 J/(mol K) and 0.885, respectively. Several statistical assessments were used to evaluate the predictive power of the model. In addition, this study provides an appropriate understanding of the most important molecular variables for exergy analysis. Compared with the LGP based model, the application of FFNN improved the r(2) to 0.914. The developed model is useful in the design of materials to achieve a desired entropy value.

Abstract
AIM neuropathy and vascular damage in this disease. Heparanase is an endoglycosidase that degrades heparan sulfate in the extracellular matrix and is believed to promote angiogenesis. The present study has been performed to investigate the effect of heparinase III (an enzyme which exclusively cleaves heparan sulfate) on wound healing in diabetic rats. METHODS The rats became diabetic by a single streptozotocin injection. Two weeks later, a wound was created by excision of the skin in the left paravertebral area. Heparinase III (0.2 unit) was injected intradermally around the wound every 5 days, starting on day one, for a total of three doses. The wound area was measured every 3 days. After completion of wound healing, full thickness skin samples were taken from the wound sites and evaluated for volume density of the collagen bundles, numerical density of the fibroblasts, and length density of the vessels. RESULTS Heparinase III accelerated wound closure compared to control diabetic animals. Microscopical examination revealed that it increased angiogenesis with no significant effect on collagen density and the number of fibroblasts. CONCLUSION Heparinase III induces angiogenesis and improves wound healing in diabetic animal model.

Abstract
INTRODUCTION Pancreatobiliary abnormalities in patients with opium addiction have not been widely evaluated by endoscopic ultrasonography before. MATERIALS AND METHODS Patients without any pancreatobiliary disease or symptom during 10 months were enrolled in this study. Common bile duct (CBD), pancreatic duct (PD) and portal vein (PV) diameters, gallbladder wall thickness and surface area of the papilla and abnormalities were evaluated in both groups by endosonography. RESULTS In total, 199 patients were evaluated. 36 (18.1%) cases were addicted to opium. Mean age of the patients was 56.0 ± 14.2 years. Opium users had a statistically significant higher (all P < 0.001) mean diameters of distal CBD (4.6 ± 1.9 vs. 3.1 ± 1.0 mm), middle part of CBD (7.5 ± 3.1 vs. 4.6 ± 1.6 mm), PD in head (3.3 ± 1.3 vs. 2.3 ± 0.7 mm) and PV (10.3 ± 2.3 vs. 8.9 ± 2.1 mm). However, the difference in the diameters of PD in the body of pancreas and gallbladder wall thickness did not reach statistical significance. The size of the papilla as measured by the surface area of the papilla of Vater was also significantly larger in opium users (40.6 ± 17.1 vs. 29.9 ± 13.5, P < 0.001). CONCLUSION Opium addicted persons have larger diameters of CBD, PV and a larger surface area of the papilla of Vater. Dilated PD only in the head of the pancreas might be an important clue to differentiate opium-induced CBD dilation from periampullary tumors and chronic pancreatitis. The clinical significance of these findings warrants further investigation.

UNLABELLED DESIGN AND PURPOSE: The purpose of this study is to investigate the effects of music-therapy on labor pain and progress in parturient primipara. Music-therapy during labor increases tolerance to pain; decreasing anxiety, it increases paturition and uterus activity and shorten labor duration. SUBJECTS AND METHODS The subjects of this research were 30 women, selected voluntarily and they have been put in two experimental and control group. This research has been conducted in the form of pre-test and post-test design. The experimental group listened to a relaxing music for 30 minutes in each hour for a two-hour period a nd the control group was not exposed to music during this period. For the purpose of gathering data in both groups, the pain scales (verbal, numeric and visual) was used to measure pain. The independent variable in this research is relaxing music and the dependent variables are the pain level and delivery progress. FINDINGS The independent t for sensations of pain in the experimental and control group before intervention has been (p = 0.875) 0.601 in numeric and visual pain and (p < 0.01) 2.92 in verbal pain, and one hour after intervention, it has been (p < 0.0001) 8.527 in visual and numeric pain and (p < 0.0001) 11.824 in verbal pain. Also, the equal value of independent t for the duration of delivery in control group before and after intervention shows that music has not had any effect on the rate of serotonin. CONCLUSION The results of statistical analysis show the effect of music on the decrease of sensation of pain in the experimental group as compared with the control group.

Abstract
Strain EB21T was isolated from a brine sample from Aran-Bidgol salt lake, a saline playa in Iran. Strain EB21T was an orange–red-pigmented, motile rod and required at least 2 M NaCl but not MgCl2 for growth. Optimal growth was achieved at 3.5 M NaCl and 0.2 M MgCl2. The optimum pH and temperature for growth were pH 7.5 and 40 °C, while it was able to grow at pH 6.0–8.0 and 25–55 °C. Analysis of the 16S rRNA gene sequence revealed that strain EB21T is a member of the family
Halobacteriaceae
, showing low levels of similarity to other members of the family. The highest sequence similarities, 91.8, 91.7 and 91.5 %, were obtained with the 16S rRNA gene sequences of the type strains of
Halobiforma lacisalsi
,
Haloterrigena thermotolerans
and
Halalkalicoccus tibetensis
, respectively. Polar lipid analyses revealed that strain EB21T contains phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and phosphatidylglycerol sulfate. Three unidentified glycolipids and one minor phospholipid were also observed. The only quinone present was MK-8(II-H2). The G+C content of its DNA was 67.7 mol%. On the basis of the data obtained, the new isolate could not be classified in any recognized genus. Strain EB21T is thus considered to represent a novel species in a new genus within the family
Halobacteriaceae
, order
Halobacteriales
, for which the name Haloarchaeobius iranensis gen. nov., sp. nov. is proposed. The type strain of Haloarchaeobius iranensis is EB21T ( = IBRC-M 10013T = KCTC 4048T).

Abstract
The solubility parameter (δ) plays a unique role in the development of stable pharmaceutical formulations for assessing phase segregation during product synthesis. Understanding this parameter helps to determine how a drug substance will behave when processed or when dosed in vivo. The aim of this work was to develop a novel comprehensive yet rapid and accurate Quantitative Structure-Property Relationship (QSPR) method based on the rank-based ant system feature selection. The method was coupled with the multiple linear regression and support vector regression and applied to the assessment of solubility parameters for a diverse dataset of 1804 chemical compounds. The models were validated by solubility prediction of 360 test set compounds which were not used in building models. The developed models have high prediction power characterized by r (2) values 0.75 and 0.82, and RMSE values 1.96 and 1.65 (J/(cm(3)))(0.5) for the external test set. Various validation techniques and comparison results with the novel optimized support vector regression indicate that the developed models can be used to determine the solubility parameters for a diverse set of chemicals with an acceptable accuracy. The developed models can be beneficial for designing new chemical materials with desired solubility parameter values.

Abstract
BACKGROUND Hippocampal damages, which are accompanied by inflammation, are among the main causes of epilepsy acquisition. We previously reported that chronic intracerebroventricular (i.c.v.) injection of lipopolysaccharide (LPS) modulates epileptogenesis in rats. There is a network of gap junction channels in the hippocampus that contribute to epileptogenesis. Gap junction channels are formed by oligomeric protein subunits called connexins (Cx). Astrocytic Cx43 and neuronal Cx36 are expressed in the hippocampus. In order to find out the possible role of gap junctions in seizure-modulating effect of LPS and neuroinflammation, we studied the effect of central administration of LPS on expression of Cx36 and Cx43 in rat hippocampus. METHODS LPS, 2.5 mug/rat/day, was injected i.c.v. to male Wistar rats for 14 days. mRNA and protein abundance of Cx36, Cx43 and IL1-β were measured in rat hippocampus by real time-PCR, Western blot and ELISA techniques, at the beginning, in the middle, and at the end of the treatment period. RESULTS IL1-β protein level was significantly increased 6 h after first injection of LPS. Cx36 and Cx43 mRNA expression did not alter during chronic administration of LPS. A selective decrease in Cx43 protein expression was observed after 7 injections of LPS. CONCLUSION It is suggested that Cx43 containing gap junctions in the hippocampus is down-regulated in response to chronic injection of LPS. This event can inhibit propagation of toxic and noxious molecules to neighboring cells and modulate hippocampal excitability and epileptogenesis.

Abstract
A Gram-positive, moderately halophilic rod, designated X5BT, was isolated from saline mud of the hypersaline lake Aran-Bidgol in Iran. Strain X5BT was a strictly aerobic, motile bacterium that produced ellipsoidal endospores at a central-subterminal position in non-swollen sporangia. The isolate grew at pH 7.0-10.0 (optimum pH 7.5), at 25-45 °C (optimum 35 °C) and with 2.5-15 % (w/v) NaCl (optimum 5-7.5 %). On the basis of 16S rRNA gene sequences, strain X5BT belonged to the genus Bacillus and showed highest similarity with Bacillus persepolensis HS136T (95.6 % 16S rRNA gene sequence similarity) and Bacillus salarius BH169T (95.5 %). The DNA G+C content was 42.4 mol%. The major cellular fatty acids were anteiso-C15:0 and iso-C15:0 and the polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, three phospholipids and two glycolipids. The diamino acid found in the cell-wall peptidoglycan was meso-diaminopimelic acid and the isoprenoid quinones were MK-7 (92 %), MK-6 (6 %) and MK-5 (2 %). On the basis of phylogenetic, chemotaxonomic and phenotypic data, a novel species of the genus Bacillus is proposed, with the name Bacillus iranensis sp. nov. The type strain is X5BT (=IBRC 10446T=DSM 23995T).
