Relation Between the Negative Cognitive Triad, Perceived Everyday Discrimination, Depressive Symptoms, and TNF-⍺ in Adolescents.

Our study is guided by Beck's cognitive stress-vulnerability model of depression. We examined the associations between perceived everyday discrimination (PED) and TNF-⍺, an inflammatory biomarker associated with risk for severe illness, through the negative cognitive triad (NCT; negative thoughts about the self, world, and future) and depressive symptoms in adolescents. We utilized a sample of 99 adolescents (36.

Subjective Sleep Quality in Women With Divorce Histories: The Role of Intimate Partner Victimization.

A marital status of divorced or separated, as opposed to married, predicts increased risk of health problems, but not for all persons. Focusing on one established health risk that has been linked with divorce--poor subjective sleep quality--the present cross-sectional study examined whether a history of physical intimate partner victimization (IPV) helps identify divorced women at potentially greater risk of health problems. Community midlife women with divorce histories, all of whom were free of current IPV, reported on their past month sleep quality and lifetime IPV.

Persistent hepatic structural alterations following nanoceria vascular infusion in the rat.

Understanding the long-term effects and possible toxicity of nanoceria, a widely utilized commercial metal oxide, is of particular importance as it is poised for development as a therapeutic agent based on its autocatalytic redox behavior. We show here evidence of acute and subacute adverse hepatic responses, after a single infusion of an aqueous dispersion of 85 mg/kg, 30 nm nanoceria into Sprague Dawley rats. Light and electron microscopic evidence of avid uptake of nanoceria by Kupffer cells was detected as early as 1 hr after infusion.

Pharmacokinetic advantage of intra-arterial cyclosporin A delivery to vascularly isolated rabbit forelimb. I. Model development.

Effective antirejection therapy with minimal systemic morbidity is required if limb transplantation is to become a clinical reality. We investigated whether i.a.
