Adversity that exhibits continuity across the life course has long-term detrimental effects on physical and mental health. Using 920 participants from the Dunedin Study, we tested the following hypotheses: (1) children (ages 3-15) who experienced adversity would also tend to experience adversity in adulthood (ages 32-45), and (2) interim personality traits in young adulthood (ages 18-26) would help account for this longitudinal association. Children who experienced more adversity tended to also experience more stressful life events as adults, β=.11, 95% CI [.04, .18], =.002. Negative emotionality-particularly its sub-facet alienation, characterized by mistrust of others-helped explain this childhood-to-midlife association (indirect effect: β=.06, 95% CI [.04, .09], <.001). Results were robust to adjustment for sex, socioeconomic origins, childhood IQ, preschool temperament, and other young-adult personality traits. Prevention of early-life adversity and treatment of young-adult negative emotionality may reduce vulnerability to later life stress and thereby promote the health of aging adults.

Rapeseed ( L.) is a major agricultural crop with diverse applications, particularly in the production of seed oil for both culinary use and biodiesel. However, its photosynthetic efficiency, a pivotal determinant of yield, remains relatively low compared with other C plants such as rice and soybean, highlighting the necessity of identifying the genetic loci and genes regulating photosynthesis in rapeseed.

Blunt abdominal trauma causing intraperitoneal injury and/or bleeding can be life-threatening, requiring immediate intervention. Diagnosing these cases can be challenging, especially when pre-existing conditions are involved. Low-grade appendiceal mucinous neoplasm (LAMN) is a rare tumor of the appendix that can lead to pseudomyxoma peritonei.

Although the pathogenesis and mechanism of congenital skeletal dysplasia are better understood, progress in drug development and intervention research remains limited. Here we report that melatonin treatment elicits a mitigating effect on skeletal abnormalities caused by deficiency. In addition to our previous finding of endoplasmic reticulum stress upon deficiency, we found calcium (Ca) overload jointly contributed to -associated chondrodysplasias.

Gestational diabetes mellitus (GDM) is a common metabolic disorder during pregnancy characterized by glucose intolerance, which poses risks to both maternal and fetal health. Baicalein, a flavonoid derived from the roots of Georgi, exhibits various biological functions and has been implicated in the modulation of several diseases. However, the regulatory effects and underlying mechanisms of Baicalein in GDM progression remain unclear.
