Under oxic conditions, hydroxyl radicals were generated with each of the four minerals. However, mineral activity showed no readily apparent correlation to ferrous content or mineral surface area. In terms of TCE and oxygen reduced per mole of ferrous iron initially present in each mineral, illite was the most reactive of the four minerals. Together, these results suggest that several ferrous minerals may contribute to abiotic dechlorination in the natural environment, and (at least for TCE reduction under anoxic conditions) measurement of ferrous mineral content and reduction potential may serve as useful tools for estimating TCE first-order abiotic dechlorination rate constants.
The comorbidity of depression and anxiety is associated with an increased risk of prolonged adverse mental health status. However, little is currently known about their genetic and environmental influences that help to explain both the comorbidity and distinctiveness. Using longitudinal twin data, the present study investigated both the overlapping and distinct relationships between depression and anxiety viewed from the perspective of Gray's Reinforcement Sensitivity Theory (RST) two personality traits of the Behavioral Inhibition and Activation Systems (BIS and BAS).

A total of 422 twin pairs (298 monozygotic and 124 dizygotic pairs) participated by completing a personality questionnaire at wave 1, and mood symptoms questionnaires at wave 2. The waves were on average 2.23 years apart.

Multivariate Cholesky decomposition indicated that the genetic variance of the personality traits (BIS and BAS) explained all of the genetic variance in depressive and anxiety symptoms. Additionally, genetic factors related to the BIS positively explained depressive and anxiety symptoms, whereas genetic factors related to the BAS negatively explained only depressive symptoms.

Limitations include shorter time interval and the reliance on self-reported data.

The present study provided evidence explaining the overlap and differentiation of depressive and anxiety symptoms by using data on personality traits in a longitudinal, genetically-informative design. The findings suggested the personality traits from Gray's RST model played an important role in the prediction, and clarified the description, of both depressive and anxiety symptoms.

Substance use remains a public health problem worldwide, and it is particularly concerning among adolescents because of its harmful effects. There is a need to better understand the factors associated with adolescents' substance use to inform policies for effective prevention.

We used data from the Global School-based Student Health Surveys. Data were collected by anonymous self-report questionnaires. This study is based on three questions assessing substance use and four questions assessing psychological distress. Logistic regression models were used to analyse associations between substance use and psychological distress. We calculated the pooled overall and regional estimates by random-effects meta-analysis.

We included 126,763 adolescents (boys, 44.7%; girls, 55.3%). Deucravacitinib Substance users tended to be older, male, physically attacked, in physical fighting, bullied; to experience psychological distress; and to have a higher socio-economic status. Alcohol use was consistently associated with medium and high psychological distress. In terms of four aspects of psychological distress, only suicidal ideation was consistently associated with the substance use components and all specific combinations of substance use. Additionally, the prevalence of alcohol use was higher than that of cigarette use and drug use. Region-wise analysis showed that substance use was associated with psychological distress in the African region, American region, South-East region and Western Pacific region.

The cross-sectional data could not infer causality.

This study indicated that high levels of substance use were significantly associated with an increased likelihood of psychological distress among adolescents. In addition, age also had an effect on substance use.

It was subsequently established that these beneficial effects may be mediated through release of paracrine factors, a kind of extracellular vesicle known as exosomes. Stem cell-secreted nano-sized exosomes have shown great potential to reduce apoptosis and inflammation, enhance angiogenesis, and improve functional behavioral recovery following spinal cord injury. This review summarizes current knowledge about the influence of exosomes derived from stem cells on spinal cord protection and regeneration with their molecular mechanisms after injury.Swine influenza A virus (SIV) is both a pathogen of economic significance to the swine industry and a potential zoonotic organism that may be transmitted to humans. We described here the detailed characterization of a role of N-terminal B-loop and CD helix of HA2 in swine influenza A virus replication. Results of our experiments demonstrated that Hemagglutinin (HA) protein of swine influenza virus could tolerate some mutations in functionally conserved B-loop and CD helix. These mutations, however, have substantially attenuated influenza virus replication in both cell lines and porcine primary tracheal epithelial cells. Significantly, we found that some B-loop or CD helix mutations generated virus mutants that replicated in MDCK and ST cell lines but failed to replicate in primary tracheal epithelial cells, thereby suggesting that swine HA protein may function as a viral virulence and pathogenesis factor. The described mutations may be further explored as attenuated vaccine candidates that can effectively prevent or eliminate the spread of influenza virus within and between swine herds.
