However, the contribution of WWTP to ARG communities was minor 11 days after the precipitation, suggesting that the storm promoted the ARG levels by introducing the input of ARGs, MGEs, and ARB from point and non-point sources, such as sewer overflow and land-applied manure. Based on a novel microbial network analysis framework, the contribution of positive biological interactions between ARGs and MGEs or bacteria was the highest one day after precipitation, indicating a promoted VGT and HGT for ARG dissemination. The microbial networks deconstructed 11 days after precipitation, suggesting the stormwater practices (e.g., tide gate opening, diversion channels, and pumping) alleviated the spread of ARGs. These results advanced our understanding of the distribution and transport of ARGs associated with their source in urban stormwater runoff.Lung growth is a critical window, when exposure to various pollutants can disturb the finely-tuned lung development and enhance risk of long-term structural and functional sequelae of lung. In this study, pregnant C57/6 mice were treated with NO2, and lungs of fetus/offspring were collected at different developmental windows and dynamic lung development was determined. The results showed that maternal NO2 exposure suppressed fetal weight, implying that fetal development can be disturbed. The time-series RNA-seq analysis of lungs showed that maternal NO2 exposure induced significant time-dependent changes in the expression profiles of genes associated with lung vein myocardium development in fetus/offspring. Most of these genes in NO2 exposure group were suppressed at middle gestation and at birth. Our results also indicated that the gene expressions of Nkx2.5 in NO2 exposure were suppressed to 0.27- and 0.44-fold of the corresponding Air group at E13.5 and PND1, and restored at later time points. This indicated that the transcription factor Nkx2.5 played an important role in abnormal lung development in fetus/offspring caused by maternal NO2 exposure. Importantly, gene expressions of lung vein myocardium development were related to transcription factors (TFs) and lung functions, and TFs showed similar trends with lung function. These results provide a comprehensive view of the adverse effects of maternal NO2 exposure on fetal lung development by uncovering molecular targets and related signaling pathways at the transcriptional level.The emissions of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) from indoor building and vehicle cabin materials can adversely affect human health. Many mechanistic models to predict the VOC/SVOC emission characteristics have been proposed. Nowadays, the main obstacle to accurate model prediction is the availability and reliability of the physical parameters used in the model, such as the initial emittable concentration, the diffusion coefficient, the partition coefficient, and the gas-phase SVOC concentration adjacent to the material surface. The purpose of this work is to review the existing methods for measuring the key parameters of VOCs/SVOCs from materials in both indoor and vehicular environments. The pros and cons of these methods are analyzed, and the available datasets found in the literature are summarized. Some methods can determine one single key parameter, while other methods can determine two or three key parameters simultaneously. The impacts of multiple factors (temperature, relative humidity, loading ratio, and air change rate) on VOC/SVOC emission behaviors are discussed. The existing measurement methods span very large spatial and time scales the spatial scale varies from micro to macro dimensions; and the time scale in chamber tests varies from several hours to one month for VOCs, and may even span years for SVOCs. Based on the key parameters, a pre-assessment approach for indoor and vehicular air quality is introduced in this review. The approach uses the key parameters for different material combinations to pre-assess the VOC/SVOC concentrations or human exposure levels during the design stage of buildings or vehicles, which can assist designers to select appropriate materials and achieve effective source control.Task-evoked pupillary response (TEPR) is a measure of physiological arousal modulated by cognitive demand. Healthy individuals demonstrate greater TEPR prior to correct versus error antisaccade trials and correct antisaccade versus visually guided saccade (VGS) trials. The relationship between TEPR and antisaccade performance in individuals with psychotic disorders and their relatives has not been investigated. Probands with schizophrenia, schizoaffective disorder, psychotic bipolar disorder, their first-degree relatives, and controls from the B-SNIP study completed antisaccade and VGS tasks. TEPR prior to execution of responses on these tasks was evaluated among controls compared to probands and relatives according to diagnostic groups and neurobiologically defined subgroups (biotypes). Controls demonstrated greater TEPR on antisaccade correct versus error versus VGS trials. TEPR was not differentiated between antisaccade correct versus error trials in bipolar or schizophrenia probands, though was greater on antisaccade compared to prosaccade trials. There was no modulation of TEPR in schizoaffective probands. Relatives of schizophrenia and schizoaffective probands and those with elevated psychosis spectrum traits failed to demonstrate differential TEPR on antisaccade correct versus error trials. No proband or relative biotypes demonstrated differential TEPR on antisaccade correct versus error trials, and only proband biotype 3 and relative biotypes 3 and 2 demonstrated greater TEPR on antisaccade versus VGS trials. Our findings suggest that aberrant modulation of preparatory activity prior to saccade execution contributes to impaired executive cognitive control across the psychosis spectrum, including nonpsychotic relatives with elevated clinical risk. Reduced pupillary modulation under cognitive challenge may thus be a biomarker for the psychosis phenotype.

Individuals with schizophrenia spectrum disorders (SSD) are at heightened risk of experiencing self-stigma, and some cultures are more stigmatizing towards SSD than others. The first purpose of this review is to provide an estimate of the relationship between self-stigma and clinical and psychosocial outcomes. The second purpose is to examine how these relationships vary across cultures.

Studies reporting correlations between self-stigma and outcome variable(s) were identified through electronic database searches from June 1, 2021, to January 2, 2022. selleck chemical Mean effect sizes were calculated using Fisher's r-to-Z-transformation.

Sixty-three articles (N=8925, 22 countries) were included in the systematic review and fifty-three articles (N=7756) were included in the meta-analysis. For the most studied clinical correlates, self-stigma had a moderate, positive correlation with depressive symptoms (r=0.49, p<.001), a moderate, negative correlation with functioning (r=-0.39, p<.001), and a positive, small correlation with severity of psychotic symptoms (r=0.29, p<.001), negative symptoms (r=0.18, p<.001) and positive symptoms (r=0.13, p=.01). For the most studied psychosocial correlates, self-stigma had a strong, negative correlation with quality of life (r=-0.52, p<.001) and self-esteem (r=-0.55, p<.001). The correlates of self-stigma were similar across cultures.

Self-stigma shows strong to small correlations with clinical and psychosocial variables similarly across cultures. More research is needed to examine underlying mechanisms to develop effective interventions.

Selenium (Se) is an effective cofactor for glutathione peroxidase (GPx), and has antioxidant effects that improve ALD. In patients with ALD, ethanol-induced oxidative damage inhibits the synthesis of related Se-containing proteins such as selenoprotein P (Sepp1), albumin (ALB), and GPx in the liver, thus decreasing the overall Se level in patients. Both Se deficiency and excess can affect the expression of GPx, resulting in damage to the antioxidant defense system. This damage enhances oxidative stress by increasing the levels of reactive oxygen species (ROS) in the body, which aggravates the inflammatory response, lipid metabolism disorder, and lipid peroxidation and worsens ALD symptoms. A cascade of oxidative damages caused by ALD will deplete selenium deposition in the body, stimulate the expression of Gpx1, Sepp1, and Gpx4, and thus mobilize systemic selenoproteins, which can restore GPx activity in the hepatocytes of ALD patients, reduce the levels of reactive oxygen species and alleviate oxidative stress, the inflammatory response, lipid metabolism disorder, and lipid peroxidation, thus helping to mitigate ALD. This review provides a reference for future ALD studies that evaluate the regulation of Se levels and contributes to studies on the potential pathological mechanisms of Se imbalance in ALD.

Previous studies evaluating the effects of selenium supplementation on lipid profile and blood pressure (BP) offer contradictory findings. This systematic review and meta-analysis assessed the effects of selenium supplementation on these lipid profile and BP.

In order to identify interrelated clinical trials, we performed a comprehensive literature search in the online databases, including PubMed, Scopus, Embase, and ISI web of science, up to December 2021.

The analysis of the data established that selenium supplementation did not significantly affect TG level (WMD -0.84mg/dL; 95% CI -4.74, 3.05, p=0.671), LDL-C (WMD 0.86mg/dL; 95% CI -1.21, 2.95, p=0.416), and HDL-C (WMD 0.3mg/dL; 95% CI -0.66, 1.27, p=0.535). however, there was a significant reduction in TC levels following selenium supplementation (WMD -2.11mg/dL; 95% CI -4.09, -0.13, p=0.037). After subgroup analysis, when the baseline levels of LDL-C were <130mg/dL, selenium supplementation elicited a significant increase in LDL-C levels (WMD 2.89mg/dL; 95% CI 0.26, 5.51, p=0.031). For BP, selenium supplementation significantly increased SBP (WMD 2.02mmHg; 95% CI 0.50, 3.55, p=0.009), while it had no significant effect on DBP (WMD 0.39mmHg; 95% CI (-0.89, 1.68, p=0.551)).

Although our findings suggest selenium may have possible therapeutic effects in improving TC and VLDL, because of its negative effects on LDL and BP, selenium supplementation for cardiovascular protection should be recommended with caution.

Classic Oil Red O formulation is based on methanol-water solution. The use of solvent can be harmful to the forensic practitioner and the environment. Moreover, solvent can destroy hand writing and biological traces. In this paper a new solvent-free Oil red O deposition method have been proposed. Experimental method is based on Oil Red O deposition from a gas phase in reduced pressure conditions. 1728 split, greasy fingermarks deposited on paper have been developed with the new method and a benchmark one. The development results have been compared. The general performance of the new method has been found inferior to the solvent based formulation. However, in most cases both methods were comparable. This shows that the experimental method could be a possible alternative to the classic one in the cases where drawbacks connected to the solvent use are unacceptable. Even though, presented results are promising, more research and optimization is necessary, before the new method can be included into the forensic expert toolbox.
