To better understand the mechanisms underlying the pulmonary O(2) uptake (V(O(2P))) slow component during high-intensity exercise, we used (31)P magnetic resonance spectroscopy, gas exchange, surface electromyography and near-infrared spectroscopy measurements to examine the potential relationship between the slow components of V(O(2P)) and phosphocreatine… (More)
PURPOSE Although it is well known that immobilization causes muscle atrophy, most immobilization models have examined lower limbs, and little is known about the forearm. The purpose of this study was to determine whether forearm immobilization produces changes in muscle morphology and function. METHODS Six healthy males (age: 21.5 +/- 1.4, mean +/- SD)… (More)
Although it is clear that rowers have a large muscle mass, their distribution of muscle mass and which of the main motions in rowing mediates muscle hypertrophy in each body part are unclear. We examine the relationships between partial motion power in rowing and muscle cross-sectional area of the thigh, lower back, and upper arms. Sixty young rowers (39… (More)
Esophageal lesions are rarely seen in patients with intestinal Behçet's disease. Three patients with esophageal lesions (dissection of esophageal mucosa, esophageal ulcer, esophageal varices) were observed among 15 patients with intestinal Behçet's disease or non-specific simple ulcer (1974-1984). Two-thirds of these fifteen patients had fully developed or… (More)
Little is known about the metabolic differences that exist among different muscle groups within the same subjects. Therefore, we used (31)P-magnetic resonance spectroscopy ((31)P-MRS) to investigate muscle oxidative capacity and the potential effects of pH on PCr recovery kinetics between muscles of different phenotypes (quadriceps (Q), finger (FF) and… (More)
Chronic administration of capsiate is known to accelerate whole-body basal energy metabolism, but the consequences in exercising skeletal muscle remain very poorly documented. In order to clarify this issue, the effect of 2-week daily administration of either vehicle (control) or purified capsiate (at 10- or 100-mg/kg body weight) on skeletal muscle… (More)
A large juvenile polyp in the ascending colon of a 5-year-old boy was successfully polypectomized . The boy often had rectal bleeding, and anemia was known. Transection was necessary to prevent bleeding and anemia.
A man was admitted to our hospital because of intestinal reddish bleeding. Colonic varices were found at the cecum by colonoscopy. Angiography of the superior mesenteric artery showed that blood vessels were scant from the end of the ileum to the ascending colon. An operative view revealed the varices, but there was no trace of the ileocecal vein. This… (More)
Localized colitis cystica profunda (CCP) is a rare condition found in the rectum. Localized CCP of 70-year-old man was found in the sigmoid colon, it was accompanied by a cancer in the ascending colon and an adenomatous polyp with focal malignancy in the sigmoid colon. Colonoscopically, the tumor appeared like a submucosal tumor.
