Microvesicles Derived from Nitric Oxide Synthase-Inhibited Endothelial Cells Promote Cell Dysfunction.

Introduction: The aims of this study were to determine (1) whether endothelial nitric oxide synthase (eNOS) inhibition stimulates endothelial microvesicles (EMVs) release and (2) the effect of EMVs derived from eNOS-inhibited cells on endothelial cell eNOS, inflammation, apoptosis, and tissue-type plasminogen activator (t-PA).

Methods: Human umbilical vein endothelial cells (HUVECs) were treated with the eNOS inhibitor (NG-nitro-l-arginine methyl ester [L-NAME], 300 µM) for 24 h. EMVs from untreated and L-NAME-treated cells were isolated, quantified, and exposed to HUVECs for 24 h.

Exploring Skin Pigmentation Adaptation: A Systematic Review on the Vitamin D Adaptation Hypothesis.

Understanding the genetic adaptations that occurred as humans migrated out of Africa to higher latitudes helps explain on a population-wide level how UV radiation (UVR) exposure will have varying consequences and benefits in patients of different skin pigmentations. It has been hypothesized that the need for efficient vitamin D synthesis was the primary driver for the skin-lightening process that evolutionarily occurred as humans migrated to higher latitudes. This review analyzes the level of support for the hypothesis that skin lightening occurred to enable adequate vitamin D synthesis in populations that migrated to areas with less UVR.
