Relationship between capillary angiogenesis, fiber type, and fiber size in chronic systemic hypoxia.

Whether chronic hypoxia causes angiogenesis in skeletal muscle is controversial. Male Wistar rats, 5--6 wk of age, were kept at constant 12% O(2) for 3 wk, and frozen sections of their postural soleus (SOL), phasic extensor digitorum longus (EDL), and tibialis anterior (TA) muscles were compared with those of normoxic controls. Capillary supply increased in SOL muscles [capillary-to-fiber ratio...

Apelin is a crucial factor for hypoxia-induced retinal angiogenesis.

OBJECTIVE To investigate the role of endogenous apelin in pathological retinal angiogenesis. METHODS AND RESULTS The progression of ischemic retinal diseases, such as diabetic retinopathy, is closely associated with pathological retinal angiogenesis, mainly induced by vascular endothelial growth factor (VEGF) and erythropoietin. Although antiangiogenic therapies using anti-VEGF drugs are effe...

Retinal oximetry measures systemic hypoxia in central nervous system vessels in chronic obstructive pulmonary disease

BACKGROUND Determination of the blood oxyhemoglobin saturation in the retinal vessels of the eye can be achieved through spectrophotometric retinal oximetry which provides access to the state of oxyhemoglobin saturation in the central nervous system circulation. The purpose of this study was to test the capability of the Oxymap T1 oximeter to detect systemic hypoxemia and the effect of suppleme...

Systemic hypoxia causes cutaneous vasodilation in healthy humans.

Hypoxia and hypercapnia represent special challenges to homeostasis because of their effects on sympathetic outflow and vascular smooth muscle. In the cutaneous vasculature, even small changes in perfusion can shift considerable blood volume to the periphery and thereby impact both blood pressure regulation and thermoregulation. However, little is known about the influence of hypoxia and hyperc...

Capillary rarefaction, hypoxia, VEGF and angiogenesis in chronic renal disease

Tubulointerstitial hypoxia and peritubular capillary rarefaction are typical features of chronic progressive renal disease. In response to low oxygen supply, hypoxia-inducible factors (HIFs) are activated but until now, it is unclear if this increased expression leads to a stabilization of the disease process and thus is nephroprotective or contributes to interstitial fibrosis and/or tubular at...
