Making full use of low-energy photons and reducing photogenerated carriers' recombination rate have been considered important ways to raise photoelectrocatalysis (PEC) efficiency. In this study, Ir-doped ZnO PEC electrodes were prepared by thermal decomposition method, first principles calculations were used to study the effects of Ir content on the electronic structure and optical properties of IrxZn1-xO coatings, the PEC degradation mechanism of the IrxZn1-xO/Ti electrodes was also tentatively presented. The results indicated that with numbers of Zn atoms replaced by Ir atoms, impurity energy level appeared in ZnO band gap, which reduced the electron transition barriers and increased the number of photogenerated carriers.  https://www.selleckchem.com/products/valproic-acid.html  Besides, IrO2 nanoparticles covered on ZnO nanorods surface, acting as highly efficient electron transfer channels and electrocatalytic active sites, could separate photogenerated electron-hole pairs and enhance PEC performance effectively. PEC performance of IrxZn1-xO/Ti electrodes with different Ir contents under UV irradiation was evaluated by rhodamine B (RhB) removal rate. Compared with pure ZnO electrodes, IrxZn1-xO/Ti ones exhibited much stronger degradation capacity. Specifically, Ir0.09375Zn0.90625O/Ti electrodes showed the highest degradation rate of 99.4 %, and a relatively high rate of 95.2 % after working 100 h continuously, indicating its excellent long-term stability. Microbe-mediated redox transformations regulate arsenic mobility in paddy soil. However, the community dynamics of the related genes, which might be affected by soil ameliorants, have not been systematically investigated during a wet-dry cycle. This study incubated arsenic-contaminated paddy soil amended with organic matter (OM), gypsum, or hematite in microcosms under alternate watering conditions. Added gypsum and hematite reduced arsenic mobility in the soil by 8-60% during the wet and dry periods. However, added OM increased arsenic mobility by 70-130% during the first 4 weeks (not the last 4 weeks) of submergence and the dry period. The results of quantitative real-time polymerase chain reaction (qPCR) depended heavily on the primers used, so the contribution of relevant genes to arsenic transformation cannot be compared using only the gene abundance assessed by qPCR. However, correlation analyses showed that the abundance and community members of the arrA gene, which mediates dissimilatory As(V) reduction [i.e., As(V) respiration], were related to soil arsenic concentrations. This was not the case for the arsC gene, which mediates cytoplasmic As(V) reduction, or the aioA gene, which mediates As(III) oxidation. These suggest that the dissimilatory pathway was mainly responsible for arsenic reduction and release in the soil studied. OBJECTIVE Few studies of eating-disorder behaviors (EDBs) in Iran have been conducted and no study has examined the occurrence of these behaviors (EDBs) among young Iranian men. This cross-sectional study examined the occurrence of EDBs, as assessed by the Eating Disorder Examination Questionnaire (EDE-Q), among young men and women in Iran. METHOD Male (n = 253) and female (n = 384) college students completed the EDE-Q. Mean scores on the EDE-Q subscales and the occurrence and regular occurrence of EDBs, namely, binge eating, self-induced vomiting, laxative misuse, extreme dietary restriction and excessive exercise, were compared between male and female participants. RESULTS Female students had higher scores on the EDE-Q Shape Concern subscale than males, whereas scores on the other subscales did not differ by gender. Male students were more likely to report self-induced vomiting (any occurrence 10.4% vs. 3.2%) and excessive exercise (28.0% vs. 20.0%) than female students. The occurrence of other EDBs did not differ by gender and binge eating was the most common EDB in both men (regular occurrence = 24.7%) and women (27.5%). CONCLUSION The findings suggest that EDBs are relatively common among college students in Iran and that most EDBs are equally common among male and female students. Prevention and health promotion programs designed to reduce the occurrence and adverse impact of EDBs may be increasingly important in Iran. Differences in trait suggestibility among those with obesity may help explain differential responses to weight-loss interventions. Ubiquitous advertising of unhealthy foods, weight-loss products that are not evidence-based, and myths regarding weight loss could be particularly sabotaging in individuals with high levels of suggestibility, with or at risk of developing obesity. This study explored relationships between suggestibility, body mass index (BMI), and self-reported eating-related behaviors that vary among those with obesity. A sample of ethnically diverse adults (N = 73) with a BMI ≥25 completed the Short Suggestibility Scale (SSS), Palatable Eating Motives Scale (PEMS), Binge Eating Scale (BES), Dutch Eating Behavior Questionnaire-Restraint (DEBQ-R), and Barratt Impulsiveness Scale (BIS). Impulsiveness was controlled in analyses due to its strong association with suggestibility. Analyses revealed that BMI was not related to SSS scores, consistent with studies using hypnotic-suggestibility scales. However, SSS scores were positively associated with eating caloric food more frequently for Reward, Social, and Conformity motives, and with greater actual dieting behavior, and binge eating. Suggestibility was not related to eating for Coping motives or effort to diet. If supported by future replications, knowledge of these associations could potentially help inform and tailor weight-loss interventions to protect those that may be most susceptible to adopting invalid messages and products. The increase in lawsuits against veterinarians based on recklessness, negligence and malpractice is a current trend since pets are increasingly viewed as part of the family, and legal action is sought if the owner is frustrated with the services rendered by the veterinarian. However, since scarce data exists on this issue, this study aims to quantify and qualify lawsuits filed against veterinarians in the state of São Paulo, Brazil to identify and correlate potential risk factors that may lead to conviction or acquittal of defendants. For this purpose, the methodology employed a search for lawsuits on the website of the São Paulo State Court of Justice, sorted by year; proceedings (summary or special civil court); plaintiff's claim (non-economic damages, economic damages, malpractice, negligence or recklessness); court decision (case granted or denied); reason for judgment (sufficient or insufficient evidence); reverse burden of proof (present or absent); type of evidence (deposition, documentary and expert testimony); value of damages claimed and awarded; location (greater São Paulo or inner state), and whether the lawsuit was filed against a veterinary clinic or hospital.
