Sex-specific associations between #erythrocyte measures and obstructive #sleep apnea

STUDY OBJECTIVES:Hypoxemic effects of obstructive sleep apnea (OSA) have been implicated in changes in erythropoiesis and hence erythrocyte measures. Sex differences are evident in both OSA and erythropoiesis. Whether sex modulates the relationship between severity of OSA and erythrocyte measures has not previously been studied.. ..RESULTS:In multiple regression models, we found significant interactions between sex and oxygen desaturation index and apnea-hypopnea index on erythrocyte measures. … Continue reading Sex-specific associations between #erythrocyte measures and obstructive #sleep apnea

The human #cerebellum has almost 80% of the surface area of the #neocortex

The surface of the human cerebellar cortex is much more tightly folded than the cerebral cortex. It was computationally reconstructed for the first time to the level of all individual folia from multicontrast high-resolution postmortem MRI scans. Its total shrinkage-corrected surface area (1,590 cm2) was larger than expected or previously reported, equal to 78% of the total surface area of the human neocortex. The unfolded … Continue reading The human #cerebellum has almost 80% of the surface area of the #neocortex
