This study examined the role of marital conflict structure--who desires and requests change versus who responds to the change request--in spouses' cardiovascular responses to marital interactions. Forty-one couples discussed 2 marital topics: one in which the wife desired change in the husband, and one in wich the husband desired change in the wife. Cardiovascular responses were assessed at 2-min intervals. Results indicated that marital conflict structure moderates cardiovascular reactivity during negative marital interactions: Husbands and wives whose interactions were characterized by high levels of negative behavior showed the most pronounced diastolic blood pressure reactivity, but only when they were in the role of desiring change in their spouses. Implications for gender difference in marital conflict physiology are considered.

Proteostasis is maintained through regulated protein synthesis and degradation and chaperone-assisted protein folding. However, this is challenging in neuronal projections because of their polarized morphology and constant synaptic proteome remodeling. Using high-resolution fluorescence microscopy, we discover that hippocampal and spinal cord motor neurons of mouse and human origin localize a subset of chaperone mRNAs to their dendrites and use microtubule-based transport to increase this asymmetric localization following proteotoxic stress.

Background: Nerve wraps composed of various autologous and bioengineered materials have been used to bolster nerve repair sites. In this study, we describe the novel use of autologous fascia nerve wraps (AFNW) as an adjunct to epineurial repair and evaluate their effect on inflammatory cytokine expression, intraneural collagen deposition and end-organ reinnervation in rats and use of AFNW in a patient case series.
Methods: Lewis rats received sciatic transection with repair either with or without AFNW, sciatic-to-common peroneal nerve transfer with or without AFNW, or sham surgery (n=14/group).

Constitutional platelet disorders have become better understood since Bernard and Soulier first described a case in 1948. Their diagnosis can also be challenging due to overlap in clinical presentation and lab findings with platelet type von Willebrand. Bernard-Soulier syndrome is a disorder caused by GPIb receptor mutations that decrease its affinity for von Willebrand factor resulting in reduced platelet function and macrothrombocytopenia.

Background: Socially isolated individuals tend to have less access to cognitively stimulating activities, which could adversely impact their cognitive health. The Internet-Based Conversational Engagement Clinical Trial (I-CONECT) intervention was designed to deliver online conversation sessions to socially isolated older old adults to prevent cognitive decline. The current study examined the intervention efficacy on participants' weekly time spent out-of-home and their social interaction with family and friends.

Background: With the continuous progress and in-depth implementation of the reform of the medical and health care system, alongside the gradual enhancement of the standardized training framework for residents, such training has become a crucial avenue for cultivating high-level clinicians and improving medical quality. However, due to various constraints and limitations in their own capabilities, residents undergoing standardized training are often susceptible to job burnout during this process. Numerous factors contribute to job burnout, which is closely associated with depression and anxiety.
