INTRODUCTION Exercise is an important countermeasure to limb muscle dysfunction in COPD. The two major training modalities in COPD rehabilitation, endurance training (ET) and resistance training (RT), may both be efficient in improving muscle strength, exercise capacity, and health-related quality of life, but the effects on quadriceps muscle characteristics have not been thoroughly described. ...
Objective—We evaluated whether phosphatidylinositol 3-kinase (PI3K ) plays a role in reparative neovascularization and endothelial progenitor cell (EPC) function. Methods and Results—Unilateral limb ischemia was induced in mice lacking the PI3K gene (PI3K / ) or expressing a catalytically inactive mutant (PI3K ) and wild-type controls (WT). Capillarization and arteriogenesis were reduced in PI3...
Nonalcoholic fatty liver disease (NAFLD) advanced to cirrhosis is often complicated by clinically significant portal hypertension, which is primarily caused by increased intrahepatic vascular resistance. Liver fibrosis has been identified as a critical determinant of this process. However, there is evidence that portal venous pressure may begin to rise in the earliest stages of NAFLD when fibro...
OBJECTIVE We evaluated whether phosphatidylinositol 3-kinase gamma (PI3Kgamma) plays a role in reparative neovascularization and endothelial progenitor cell (EPC) function. METHODS AND RESULTS Unilateral limb ischemia was induced in mice lacking the PI3Kgamma gene (PI3Kgamma-/-) or expressing a catalytically inactive mutant (PI3Kgamma(KD/KD)) and wild-type controls (WT). Capillarization and a...
In this study, we examined whether glycemic status influences aerobic function in women with type 1 diabetes and whether aerobic function is reduced relative to healthy women. To this end, we compared several factors determining aerobic function of 29 young sedentary asymptomatic women (CON) with 9 women of similar age and activity level with type 1 diabetes [DIA, HbA1c range = 6.9-8.2%]. Calf ...
Most hypervascular nodules in a cirrhotic liver are hepatocellular carcinomas (HCCs); however, some are benign hypervascular hyperplastic nodules. We report a case of benign hypervascular hyperplastic nodules in a 41-year-old male patient without hepatitis B or C virus infection, with a history of alcohol abuse, and diagnosed with an aortic aneurysm. The dynamic computerized tomography of the l...
The unweighting model is a unique whole animal model that will permit the future delineation of the mechanism(s) by which gravity maintains contractile mass in postural (slow-twitch) skeletal muscle. Since the origination of the model of rodent hindlimb unweighting almost one decade ago, about half of the 59 refereed articles in which this model was utilized have been published in the Journal o...
To evaluate if enalapril treatment can influence skeletal muscle metabolism and histology we investigated 26 patients with congestive heart failure and 20 normal subjects. The patients were treated with enalapril for 3 months in addition to diuretics and digitalis. Biopsies from the lateral vastus muscle were taken before and after treatment. Citrate synthetase, 3-hydroxyacyl-CoA dehydrogenase ...
We summarize our morphometric data on fiber vascularization and aerobic capacity in red muscle of tuna (Katsuwonus pelamis), compared to intensely aerobic flight muscles of hummingbird (Selasphorus rufus, BW 3-4 g) and bat (Eptesius fuscus, BW 15-16 g, Pipistrellus hesperus, BW 3-5 g). Three characteristic features of high flux paths for oxygen: (a) small fiber size, (b) dense capillary network...
