Low force exercise training with blood flow restriction (BFR) elicits muscle hypertrophy. We investigated the effects of microvascular hypoxia (i.e., low microvascular O2 partial pressures, PmvO2 ) during contractions on hypertrophic signaling, growth response and key muscle adaptations for increasing exercise capacity. Wistar rats were fitted with a cuff placed around the upper thigh and inflated to restrict limb blood flow. Low force isometric contractions (30 Hz) were evoked via electrical stimulation of the tibialis anterior (TA) nerve...

Background: The skeletal muscle toxicity that accompanies the chemotherapy drug doxorubicin (DOX) may lead to cancer patient weakness and fatigue. This myotoxicity involves myogenic regulatory factor (MRF) disruption which alters muscle integrity and regeneration. Endurance exercise enhances MRF expression and thereby may mitigate DOX-induced MRF disruptions. This study examined the effects of endurance training and DOX treatment on myogenic regulatory factor (MRF) expression. Methods: Male rats were exercise trained (EXER) or remained sedentary (SED) for two weeks...

Two separate liquid chromatography (LC)-mass spectrometry (MS) methods were developed for determination and quantification of water-soluble and fat-soluble vitamins in human tear and blood serum samples. The water-soluble vitamin method was originally developed to detect vitamins B1, B2, B3 (nicotinamide), B5, B6 (pyridoxine), B7, B9 and B12 while the fat-soluble vitamin method detected vitamins A, D3, 25(OH)D3, E and K1. These methods were then validated with tear and blood serum samples. In this data in brief article, we provide details on the two LC-MS methods development, methods sensitivity, as well as precision and accuracy for determination of vitamins in human tears and blood serum...

INTRODUCTION: Chronic mitral regurgitation (MR) is characterized by adverse ventricular remodeling and progressive LV dysfunction leading to heart failure (HF). Beta-blockers (BB) improve LV remodeling and prognosis in patients with HF. As chronic severe MR results in neuroendocrine activation similar to HF, it is likely that BB may also exert favorable effects in these patients. No study has assessed the role of oral BB therapy in chronic rheumatic MR. AIMS: A total of 100 patients of chronic rheumatic MR (mean age 30±13...
