This study examined adolescents' perceptions concerning the presence of guns in their school and the adolescents' emotional and behavioral responses associated with these perceptions. Survey data from 376 African-American sixth, seventh, and eighth grade students of a low-income area of a North Carolina city were studied. Twenty-eight percent of adolescents reported that other students brought guns to school, 36% felt afraid that someone would hurt or attack them while at school, 15% avoided school (or places in school) because of fear that a student would hurt or attack them, and 20% carried weapons to school for self-protection. Logistic regression analyses found that, compared to their peers, adolescents who perceived that their school mates brought guns to school were almost twice as likely to experience fear while at school, were more than three times more likely to exhibit school avoidance behavior, and were more than twice as likely to bring a weapon to school themselves for self-protection. Educators and school health professionals are urged to work together to address these problems concerning school safety.

Mesenchymal stem cells (MSCs) are pluripotent stem cells with self-renewal. They play a critical role in cell therapy due to their powerful immunomodulatory and regenerative effects. Recent studies suggest that one of the key therapeutic mechanisms of MSCs seems to derive from their paracrine product, called extracellular vesicles (EVs).

Two Gram-stain-negative, curved-rod-shaped, non-motile and aerobic bacteria W6 and I13 were isolated from marine sediment samples collected from Meishan Island located in the East China Sea. Catalase and oxidase activities and hydrolysis of Tween 40, 60 and 80 were positive for both strains, while nitrate reduction, indole production, methyl red reaction and HS production were negative. Phylogenetic analyses based on 16S rRNA and genome sequences revealed that strains W6 and I13 formed distinct phylogenetic lineages within the genera and , respectively.

In recent years, workplace violence has become an escalating concern, particularly within the healthcare sector. Healthcare workers, who dedicate their lives to caring for others, are increasingly facing violence within their workplaces as evidenced by existing studies. However, literature overlooks complex associations between workplace violence, workplace stress, and domestic violence and stress.

Extracting natural active ingredients from plants is an effective way to develop and screen modern drugs. Psoralea corylifolia is a leguminous plant whose seeds have long been used as a Traditional Chinese Medicine to treat psoriasis, rheumatism, dermatitis, and other diseases. To date, several main compounds, including coumarins, flavonoids, monoterpene phenols, and benzofurans, have been identified from the seeds of Psoralea corylifolia.
