A mouse monoclonal antibody to Hydra attenuata was used to demonstrate immunoreactive product in neurons in situ, in both whole mount and sectioned hypostomes and tentacles of H. oligactis and H. littoralis. Immunoreactive cells were concentrated around the mouth and scattered along the length of the tentacles. In the hypostome, nerve cells sent one or more(More)
BACKGROUND Resection of hepatocellular carcinoma is potentially curative, but local recurrence is common. In this prospective randomised trial, we aimed to find out if one dose of postoperative adjuvant intra-arterial iodine-131-labelled lipiodol could reduce the rate of local recurrence and increase disease-free and overall survival. METHODS Patients who(More)
As hemodynamics is widely believed to correlate with anastomotic stenosis in coronary bypass surgery, this paper investigates the flow characteristics and distributions of the hemodynamic parameters (HPs) in a coronary bypass model (which includes both proximal and distal anastomoses), under physiological flow conditions. Disturbed flows (flow(More)
OBJECT We wish to report our experience in the management of residual or recurrent intracranial aneurysm after previous endovascular or surgical treatment. METHODS We performed a retrospective review of the clinical notes, operation records and cerebral angiograms of eighteen patients who were known to have undergone treatment for residual or recurrent(More)
Inspired by superior flight performance of natural flight masters like birds and insects and based on the ventilating flaps that can be opened and closed by the changing air pressure around the wing, a new flapping wing type has been proposed. It is known that the net lift force generated by a solid wing in a flapping cycle is nearly zero. However, for the(More)
Microcysts are most evident in the posteroventral and anteroventral cochlear nuclei (PVCN and AVCN) of the Mongolian gerbil. The origin and contents of the microcyst are not elucidated at present. The present study investigated the possible inclusions in the microcyst by employing immunocytochemical labeling to localize the existence of various protein(More)
Longitudinal and transverse velocity increments are measured both temporally and spatially using two X-wire probes in the intermediate region of a cylinder wake over Taylor microscale Reynolds numbers in the range of 100-300. The scaling exponents of both the spatial and temporal longitudinal velocity increments agree favorably with the predictions of(More)
Posterior fossa dural arteriovenous fistulae in children are rare lesions that are difficult to treat effectively. We report a case of a 2-year-old girl with such a fistula, who presented clinically with progressive neurological deficit. The lesion was treated by endovascular occlusion, resulting in radiological and clinical cure.
In an earlier study (Chua et al., 1998, 1999a), a 5:1 enlarged model of the Kyoto-NTN Magnetically Suspended Centrifugal Blood Pump (Akamatsu et al., 1995) with five different impeller blade profiles was designed and constructed. Their respective flow characteristics with respect to (1) the three different blade profile designs: forward, radial, and(More)
This study investigated the morphological changes and glial fibrillary acidic protein immunoreactivity (GFAP-IR) in the anteroventral cochlear nucleus (AVCN) of acoustically-deprived gerbils during postnatal development. The mongolian gerbil, Meriones unguiculatus, had been acoustically deprived on the right side or left side by a surgical ligation of the(More)
