The relationship between self-oriented perfectionism and exercise participation: based on the dualistic model of passion.

Background: During the critical formative years of college, active participation in sports not only helps to alleviate stress, but also promotes the development of healthy habits. Although the multifaceted benefits of exercise have been widely recognized, there is a relative dearth of research on the relationship between personality traits, particularly college students' self-oriented perfectionism (SOP), and exercise participation.

Methods: A questionnaire survey of 374 college students was conducted using the snowball sampling method.

Risks of passive use of social network sites in youth athletes: a moderated mediation analysis.

Background: With the popularity of social media platforms, the use of social networks challenges the well-being and mental health of athletes.

Motivation: Despite ongoing scholarly discussions about the effects of passive use of social network sites, few studies have examined the relationship between the passive use of social network sites and mental health in young athletes from a social comparison perspective.

Hypothesis: To address this research gap, we draw on the social comparison and developmental systems theories to explore the mediating effect of upward social comparison on passive social network site use and mental health, as well as the moderating effects of positive psychological capital.

Mechanistic study of PDIA1-catalyzed TFF3 dimerization during sepsis.

Aims: Trefoil factor 3 (TFF3) is a gut mucosal protective molecule that is secreted by intestinal goblet cells. The dimeric structure of TFF3 enables it to function in intestinal mucosal repair and to maintain its own stability. Protein disulfide isomerase a1 (PDIA1) can directly catalyze the formation, isomerization and reduction of disulfide bonds in proteins and may play an important role in the formation of TFF3 dimer.

The role of PDIA3 in myogenesis during muscle regeneration.

Beta 3 (β3) integrin plays an important role in the initiation of myogenesis in adult muscle. Protein disulfide isomerases (PDIs) can activate β3 integrin in various cells to promote cell migration, adhesion and fusion. However, the effect of PDIs on myogenesis during muscle regeneration has not been elucidated.
