Copolyesters of 3-hydroxybutyrate (3HB) and 3-hydroxyvalerate (3HV) have been produced by Alcaligenes eutrophus in nitrogenfree culture solutions of butyric and pentanoic acids. When pentanoic acid was used as the sole carbon source, a copolyester with an unusually high 3HV fraction of 90 mol% was produced. Copolyesters with a wide range of compositions(More)
 Coordination between the left and right limbs during cyclic movements, which can be characterized by the amplitude of each limb's oscillatory movement and relative phase, is impaired in patients with Parkinson's disease (PD). A pedaling exercise on an ergometer in a recent clinical study revealed several types of coordination disorder in PD patients. These(More)
OBJECTIVE Following anterior cruciate ligament (ACL) reconstruction, restricted weight bearing and immobilization results in thigh and calf muscle atrophy and weakness. The purpose of this study was to assess the effect of electrical muscle stimulation (EMS) on prevention of muscle atrophy in patients during the early rehabilitation stage after ACL(More)
The aim of this study was to investigate the effect of low-intensity exercise training using belt electrode skeletal muscle electrical stimulation on muscle strength and cardiorespiratory fitness in healthy subjects. Nineteen healthy subjects were allocated into control or intervention groups; in both groups the participants kept regular physical activity(More)
A rare case of recurrent cervical cancer presenting multiple metastases to the small intestine is reported. A 69-year-old Japanese woman with a past history of early-stage (Ia) cervical cancer 13 years previously suffered sudden onset of panperitonitis caused by perforation of the small intestine. In the perforated lesion, squamous cell carcinoma, which was(More)
Patients with Parkinson's disease (PD) may develop pulmonary dysfunction, but the pathogenesis remains unclear. We investigated a correlation between thoracoabdominal movements and pulmonary function in seven patients with PD and 14 healthy controls. We measured vital capacity (VC) and forced vital capacity (FVC) using an autospirometer, and measured chest(More)
A 16-year-old male with exertional heat stroke (EHS) had extensive hepatocellular damage, severe rhabdomyolysis, renal failure, and coma. Hemodiafiltration was started on day 2 and living donor liver transplantation was performed on day 3. He received continuous mechanical ventilation with intubation before and after the surgery. As his mental status(More)
The present study investigated the effects of variations in solar radiation on endurance exercise capacity and thermoregulatory responses in a hot environment. Eight male volunteers performed four cycle exercise trials at 70 % maximum oxygen uptake until exhaustion in an environmental chamber maintained at 30 °C and 50 % relative humidity. Volunteers were(More)
A generally recognized concept dictates that surgical intervention for non-parasitic cysts of the liver is mostly palliative such as aspiration of the content, suture and closure, internal or external drainage, marsupialization, and unroofing of the cyst, while total excision of the entire cyst, which sometimes necessitates hepatic resection, is not usually(More)
The purpose of this study was to evaluate the inhibitory effect of procaterol (procaterol hydrochloride, CAS 62929-91-3) on exercise dynamic lung hyperinflation during the 6-min walk test (6MWT) in stable chronic obstructive disease (COPD) patients. Fourteen patients with stable COPD who were referred to our clinic between July 2008 and October 2009 were(More)
