We review research and theory examining stress and coping in stepfamilies as predictors of marital quality and divorce. Although the divorce rate in first-marriages has stabilized after years of increase in North America, the divorce rate of remarriages continues to increase. We argue that depression and marital distress are both mechanisms through which stepfamily stress impacts marital stability, with parenting stressors particularly potent determinants of divorce. We draw upon our own research predicting divorce across 20 years in 112 married couples in stepfamilies, as well as from the larger literature on stepfamilies.

Background: Stemona tuberosa, a vital species in traditional Chinese medicine, has been extensively cultivated and utilized within its natural distribution over the past decades. While the chloroplast genome of S. tuberosa has been characterized, its mitochondrial genome (mitogenome) remains unexplored.

Orexin receptors constitute a family of class A G-protein coupled receptors. There are two subtypes of orexin receptors, namely OX1R and OX2R. OX1R and OX2R are widely distributed in the central nervous system and are the targets for the peptide neurotransmitters orexin-A and orexin-B.

The okaramine family of compounds, a class of alkaloids with broad-spectrum insecticidal activity, has been discovered from species of and . These okaramines, characterized by their complex structures and diverse biological activities, have attracted widespread attention from biologists and chemists. To date, only a few okaramines have been synthesized, notably the highly active okaramines A and B, which feature a polycyclic skeleton, including an azocine ring and an unprecedented 2-dimethyl-3-methyl-azetidine ring.

G protein-coupled receptors (GPCRs) represent the largest family of membrane receptors and are highly effective targets for therapeutic drugs. GPCRs couple different downstream effectors, including G proteins (such as Gi/o, Gs, G12, and Gq) and β-arrestins (such as β-arrestin 1 and β-arrestin 2) to mediate diverse cellular and physiological responses. Biased signaling allows for the specific activation of certain pathways from the full range of receptors' signaling capabilities.

Introduction: The absence of a biological parent from a child's existence had a negative impact on the child's growth, socialization, psychological wellbeing, and economic productivity. Developing nations like Ethiopia experience a huge number of orphans and family-unbounded children. But the exact figure has not been reported yet at the national level recently.
