Notes

Sphingadienine-1-phosphate ranges are usually controlled by the book glycoside hydrolase family members 1 glucocerebrosidase widely distributed in seedling plants.
Therefore, this study reminds researchers of the presence of MAUP and the necessity to minimize this problem while exploring the environmental determinants of the COVID-19 outbreak.Objective Recent evidence indicates that inhibition of prolyl hydroxylase domain (PHD) proteins can exert beneficial effects to improve metabolic abnormalities in mice and humans. However, the underlying mechanisms are not clearly understood. This study was designed to address this question. Methods A pan-PHD inhibitor compound was injected into WT and liver-specific hypoxia-inducible factor (HIF)-2α KO mice, after onset of obesity and glucose intolerance, and changes in glucose and glucagon tolerance were measured. Tissue-specific changes in basal glucose flux and insulin sensitivity were also measured by hyperinsulinemic euglycemic clamp studies. Molecular and cellular mechanisms were assessed in normal and type 2 diabetic human hepatocytes, as well as in mouse hepatocytes. Results Administration of a PHD inhibitor compound (PHDi) after the onset of obesity and insulin resistance improved glycemic control by increasing insulin and decreasing glucagon sensitivity in mice, independent of body weight change. Hyperinsulinemic euglycemic clamp studies revealed that these effects of PHDi treatment were mainly due to decreased basal hepatic glucose output and increased liver insulin sensitivity. Hepatocyte-specific deletion of HIF-2α markedly attenuated these effects of PHDi treatment, showing PHDi effects are HIF-2α dependent. At the molecular level, HIF-2α induced increased Irs2 and cyclic AMP-specific phosphodiesterase gene expression, leading to increased and decreased insulin and glucagon signaling, respectively. These effects of PHDi treatment were conserved in human and mouse hepatocytes. Conclusions Our results elucidate unknown mechanisms for how PHD inhibition improves glycemic control through HIF-2α-dependent regulation of hepatic insulin and glucagon sensitivity.Background The effect of household pesticide exposure on depressive symptoms in the general population is underexplored, and the role of exercise in the association between pesticide exposure and depressive symptoms is unclear. Objective The goals of this study are to examine whether the associations between household pesticide exposure and depressive symptoms exist in the general population, and whether exercise can attenuate these associations. Methods We used data from the 2005-2014 National Health and Nutrition Examination Surveys (NHANES), including a total of 14708 US adult participants who were 20 years or older. Depressive symptoms were assessed using the Patient Health Questionnaire (PHQ-9). Exercise information on the recreational physical activity (RPA) and pesticide exposure were self-reported in an interview. Results Participants with exposure of household pesticide had a higher odds ratio ([OR]; OR = 1.32, 95% confidence intervals [CI] 1.12-1.56) for depressive symptoms, compared to those who had not been unexposed. A significant interaction between exercise and pesticide exposure on depressive symptoms was observed (P = 0.038). Stratified analysis showed that household pesticide exposure was associated with a 50% higher risk of depressive symptoms (OR = 1.50, 95% CI 1.20-1.86) in the population with light RPA. selleck products However, we did not find a significant association in the group with moderate + vigorous RPA (P = 0.305). Conclusion This study further confirms that household pesticide exposure is associated with an elevated risk of depressive symptoms in the general population. More importantly, we for the first time reports that moderate + vigorous RPA attenuates the positive association between household pesticide exposure and depressive symptoms.The Han River watershed is the largest and most important source of drinking water for the residents of the Seoul metropolitan area and the Gyeonggi province in South Korea. The tributaries of the watershed are vulnerable to contamination by effluents from nearby wastewater treatment plants (WWTPs) and non-point sources. In this study, a one-year monitoring study was performed to investigate the occurrence of 13 pharmaceuticals in 24 tributaries of the Han River watershed in October 2015. From the 13 pharmaceuticals, 12 were found in at least one sample, with the exception of chlortetracycline, which was not detected. The three most frequently detected compounds were clarithromycin (95.8%), carbamazepine (66.7%), and lincomycin (62.5%). Compounds found in high concentrations included clarithromycin (5.2675 μg L-1), ibuprofen (1.9646 μg L-1), and carbamazepine (1.1009 μg L-1). The total concentration of 12 pharmaceuticals in the Seoul metropolitan area (0.7128 μg L-1) was higher than that in the Gyeonggi area (0.3177 μg L-1) possibly due to the large-scale WWTPs located upstream. However, in IHR-3, which is located at the very upstream of the tributary and is not impacted by a WWTP, pharmaceuticals were not detected. This can be explained by the fact that most pharmaceuticals derived from WWTPs are related to human activity. The risk quotients (RQs) for the target pharmaceuticals were calculated on the basis of their presence in tributaries, and all pharmaceuticals presented RQs less then 0.01, indicating that potential environmental impacts should be low. These results will be useful to monitor and assess the potential environmental risks of pharmaceuticals in the surface water.Background The association between ambient air pollutants exposure and suicidal ideation (SI) has rarely been explored, especially in Chinese population. Therefore, we aimed to investigate the long-term effects of ambient air pollutants on SI among a Chinese rural population. Method We recruited 29997 participants from the Henan Rural Cohort study in 2016-2017. SI was evaluated by using the ninth item of the Patient Health Questionnaire-9 (PHQ-9) in the baseline survey. We adopted a satellite-based spatiotemporal model to estimate participants' exposure to particulate matters (PMs) (PM with an aerodynamic diameter ≤1 μm (PM1), ≤2.5 μm (PM2.5) or ≤10 μm (PM10), respectively) and nitrogen dioxide (NO2), and then calculated the 3-year average concentrations of the four pollutants. We used logistic regression models to explore the association between long-term exposure to ambient air pollutants and SI. In addition, we conducted several stratified analyses to examine effect modification of selected factors. Results The odds ratios (95% confidence intervals [CI]) of SI in response to each 1 μg/m3 increase in PM1, PM2.
