OBJECTIVE C-reactive protein (CRP), an obesity-related inflammatory marker, is a promising predictor for cardiovascular disease and may be a mediator for atherogenesis. It has been reported that diet-induced weight loss lowered CRP levels. However, the effect of exercise training, another therapy that can reduce weight, on CRP is still unclear. We examined(More)
The effect of 2-nicotinamidoethyl nitrate (nicorandil, SG-75, Sigmart) on coronary circulation was studied in conscious dogs, instrumented previously under sterile condition with sonomicrometers for the external coronary diameter measurement, and an electromagnetic flow plobe on the left circumflex coronary artery and a catheter into the thoracic aorta.(More)
The relationship between plasma norepinephrine (NE), epinephrine (E) and dopamine-beta-hydroxylase activity (DBH) was studied in 90 cardiac patients (New York Heart Association [NYHA] classes I-IV), 85 healthy control subjects and 18 competitive skiers. The cardiac patients in NYHA classes III and IV had significantly higher NE (p less than 0.001) and lower(More)
BACKGROUND Several studies have indicated that skeletal muscle is important in determining the exercise capacity of patients with chronic heart failure (CHF). However, this theory has been investigated only in experiments based on local exercise involving a small muscle mass. We investigated skeletal muscle metabolism during maximal systemic exercise to(More)
The effects of alpha-human atrial natriuretic peptide (alpha-hANP) on the coronary circulation were compared with those of nitroglycerin in 16 conscious dogs chronically instrumented with a pair of miniature sonomicrometers and an electromagnetic flow probe placed on the left circumflex coronary artery. alpha-hANP (1 and 10 micrograms) and nitroglycerin(More)
To assess exercise energy metabolism of forearm flexor muscles in rowers, six male student rowers and six control subjects matched for age and sex were studied using phosphorus-31 magnetic resonance spectroscopy (31P-MRS). Firstly, to adjust for the effect of differences in cross-sectional muscle area, the maximal cross-sectional area (CSAmax) of the(More)
The purpose of this study was to construct a simple ergometer for the 31P NMR spectroscopic study of dynamic forearm exercise in a whole body magnetic resonance imaging system and to evaluate the total system and the physiological response to this type of exercise using a multistage protocol. The system consisted of a completely nonmagnetic assembly(More)
OBJECTIVE To estimate muscle metabolism and oxygen delivery to skeletal muscle in patients with chronic heart failure. METHODS 13 patients with chronic heart failure and 15 controls performed calf plantar flexion for six minutes at a constant workload of 50% of one repetition maximum. During recovery from exercise, skeletal muscle content of oxygenated(More)
We report herein the cases of two patients who underwent complete resection of a superior sulcus tumor (SST) plus adjuvant brachytherapy, with the area to be irradiated determined by a computer program system designed to minimize unnecessary irradiation to the normal components and to optimize the effect on the targeted area. Although the efficacy of(More)
