Sanitation of seawater effluent from seaweed processing plants using a photo-catalytic TiO2 oxidation.

A fine porcelain open-cell photo-catalytic filter with titanium dioxide (TiO(2)) was evaluated for sterilization and sanitation of bio-polluted industrial water. In simulated seawater industrial effluent samples, the populations of Escherichia coli and Vibrio parahaemolyticus quickly decreased and reached non-detectable level within 10min. In seawater effluents from a seaweed processing plant, the bacterial populations in two samples quickly decreased by more than 10(3).

The rat pink-eyed dilution (p) mutation: an identical intragenic deletion in pink-eye dilute-coat strains and several Wistar-derived albino strains.

We identified the rat pink-eyed dilution (p) and pink eye Mishima (p(m)) mutations. The p(m) mutation, which was isolated from a wild rat caught in Mishima Japan in 1961 and is carried in the NIG-III strain, is a splice donor site mutation in intron 5. The p mutation, which was first described in 1914 and is carried in several p/p rats including the RCS and BDV strains, is an intragenic deletion including exons 17 and 18.

Study of portal vein thrombosis in patients with idiopathic portal hypertension in Japan.

Background/aims: The aim of this study was to elucidate the incidence and clinical manifestations of portal vein thrombosis (PVT) in patients with idiopathic portal hypertension (IPH) in Japan during long-term follow-up.

Patients And Methods: Twenty-two patients with IPH were examined for PVT by sonography during a follow-up of 12+/-6 years. Clinical manifestations and patient outcome related to PVT were studied.

Effect of cholecystokinin1 receptor antagonist loxiglumide (CR1505) on basal pancreatic exocrine secretion in conscious rats.

Introduction And Aim: To examine the involvement of cholecystokinin (CCK) in the basal pancreatic exocrine, we investigated the effect of loxiglumide (CR1505), a CCK1 receptor antagonist, on basal pancreatic exocrine secretion in conscious rats.

Methodology: After the basal collection of pancreatic juice for 1 hour, loxiglumide (10 mg/kg/h) or saline was infused via the femoral vein continuously for 2 hours.

Results: Loxiglumide significantly suppressed the basal pancreatic protein and amylase outputs.

Sub-zero temperature inactivation of carboxypeptidase Y under high hydrostatic pressure.

High hydrostatic pressure induced cold inactivation of carboxypeptidase Y. Carboxypeptidase Y was fully active when exposed to subzero temperature at 0.1 MPa; however, the enzyme became inactive when high hydrostatic pressure and subzero temperature were both applied.
