A new gene, termed klotho, has been identified that is involved in the suppression of several ageing phenotypes. A defect in klotho gene expression in the mouse results in a syndrome that resembles human ageing, including a short lifespan, infertility, arteriosclerosis, skin atrophy, osteoporosis and emphysema. The gene encodes a membrane protein that(More)
Our previous study reported that metabolic stress in skeletal muscle achieved by combining moderate blood flow restriction (BFR) with low-intensity resistance exercise at 20% of one repetition maximum (1 RM) could not reach the level achieved by high-intensity resistance exercise. Since the previous protocol is typical of current regimens of this type, we(More)
Follow-up studies on 3,195 patients from 161 centers in Japan undergoing continuous ambulatory peritoneal dialysis (CAPD) were performed for 1-104 months to clarify the incidence as well as the clinical features of acute hydrothorax. In these studies, 50 patients (1.6%) developed this complication. Twenty-seven (54%) were men, and 23 (46%) were women,(More)
Changes in peroxisomal CoA pools in the liver of fasted, diabetic, high-fat diet-fed and clofibrate-treated rats were studied. Total-CoA increased slightly in the fasted group and markedly in the diabetic, high-fat and clofibrate-treated groups. Fractionation studies showed that changes in free CoA levels were much greater in peroxisomes than in(More)
We have recently identified a novel gene, klotho (kl), which may suppress several aging phenotypes. A defect of kl gene expression in the mouse results in a syndrome resembling human aging, such as arteriosclerosis, skin atrophy, osteoporosis, and pulmonary emphysema. To determine whether mouse homozygotes for the kl mutation (kl/kl) show abnormal glucose(More)
The amino acid sequence of jack bean urease has been determined. The protein consists of a single kind of polypeptide chain containing 840 amino acid residues. The subunit relative molecular mass calculated from the sequence is 90,770, indicating that urease is composed of six subunits. Out of 25 histidine residues in urease, 13 were crowded in the region(More)
Two long-chain acyl-CoA hydrolases, referred to as ACH1 and ACH2, were purified from the liver cytosol of rats fed a diet containing di(2-ethylhexyl)phthalate, a peroxisome proliferator. The molecular mass of ACH1 was estimated to be 73 kDa by gel filtration, and that of the subunits, 36 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The(More)
Long-chain acyl-CoA hydrolase (EC, which is found primarily in the brain in rats, catalyzes the hydrolysis of fatty acyl-CoA thioesters. We purified this enzyme, referred to as ACH, from the rat brain cytosol. The molecular masses of the native enzyme and the subunit were estimated to be 104 and 36 kDa, respectively. The enzyme showed high activity(More)
Although recent studies have reported that low-intensity resistance training with blood flow restriction could stress the muscle effectively and provide rapid muscle hypertrophy and strength gain equivalent to those of high-intensity resistance training, the exact mechanism and its generality have not yet been clarified. We investigated the intramuscular(More)
The ability of di(2-ethylhexyl)phthalate (DEHP), a very widely used commercial plasticizer, to induce hepatic microsomal carboxylesterase isozymes in rats, mice (C5BL/6 and DBA/2 strains), and hamsters was studied by measuring hydrolase activities and by immunoblotting analysis using specific antibodies. Animals were given 2% (v/w) DEHP in the diet for 7(More)
