BACKGROUND Empty fruit bunch (EFB) has many advantages, including its abundance, the fact that it does not require collection, and its year-round availability as a feedstock for bioethanol production. But before the significant costs incurred in ethanol production from lignocellulosic biomass can be reduced, an efficient sugar fractionation technology has(More)
Cultured cells of the human urinary bladder smooth muscle are useful for investigating bladder function, but methods for culturing them are not well developed. We have now established a novel enzymic technique. The smooth muscle layer was separated out and incubated with 0.2% trypsin for 30 min at 37 degrees C. The samples were then minced and incubated(More)
PURPOSE To compare the success rates and stabilities of postoperative alignment between adjustable and the non-adjustable surgeries in the treatment of sensory exotropia. METHODS A retrospective analysis was performed on all patients with sensory exotropia who had undergone unilateral lateral rectus recession and medial rectus resection (R&R) between(More)
Electromyographic activities of the ipsilateral cremaster muscle evoked by electrical stimulation of either the thigh or the penis were analyzed for latencies and burst durations. Response latencies were 30 ms on thigh stimulation and 30-35 ms on penile stimulation. With the increase in stimulus intensity the latencies decreased to 30 ms in both cases. The(More)
Motor unit action potentials (MUPs) of the external urethral sphincter muscle during cystometry were analysed on six normal males. Electrodes were of concentric needle type having the exposed tip surface of 0.07 mm2, and the potential changes were analysed by automatic decomposition electromyography (ADEMG), for isolation and characterization of unit(More)
On 6 female mongrel dogs (denervated group), bilateral hypogastric nerves were cut distally to the inferior mesenteric ganglion. Five dogs were kept intact as a control group. After 2-5 months, urethral pressure response to continuous noradrenaline infusion (0.1 microgram/kg/min) was monitored. The urethral pressure rose significantly after noradrenaline(More)
Tests for evaluating the function of the nervous system in patients with erectile impotence have been performed indirectly with the measurement of nerve conduction velocity in the extremities and other neurological procedures, since it has been technically difficult to measure the nerve conduction velocity of the dorsal nerve of the penis. Calculation of(More)
Sympathetic skin responses were elicited from the palm and sole (plantar) with electrical stimulation on the dorsal nerve of the penis in 24 individuals. The palmar and plantar sympathetic skin responses were obtained in 12 subjects with normal ejaculatory function. On the other hand, the plantar sympathetic skin response was absent in 11 of 12 patients who(More)
