The effect of decompression on the structure of Methanococcus jannaschii, an extremely thermophilic deep-sea methanogen, was studied in a novel high-pressure, high-temperature bioreactor. The cell envelope of M. jannaschii appeared to rupture upon rapid decompression (ca. 1 s) from 260 atm of hyperbaric pressure. When decompression from 260 atm was performed over 5 min, the proportion of ruptur...
OBJECTIVES To develop strategies to recruit and retain inactive older adults into a physical activity program. METHODS Names of 7378 older adults were obtained from 60 neighborhoods. Then, 6401 potential subjects were matched to telephone numbers and phoned. Subjects meeting the screening criteria were invited to join the program (n = 4209). Walk leaders and social support were used to enhanc...
The distribution of cobalamin cofactors was investigated in the livers and tumors of rats bearing transplanted Morris 7777 or 7800 hepatomas, in the livers of rats treated with the hepatocarcinogen diethylnitrosamine, and in normal rats. There was a significant increase in the proportion of methylcobalamin both in livers and tumors from rats bearing the hepatomas 7777 and 7800 compared to the p...
Mice lacking the transcription factor NF-E2 p45-related factor 2 (Nrf2) develop more severe nonalcoholic steatohepatitis (NASH), with cirrhosis, than wild-type (Nrf2(+/+)) mice when fed a high-fat (HF) diet for 24 weeks. Although NASH is usually associated with insulin resistance, HF-fed Nrf2(-/-) mice exhibited better insulin sensitivity than HF-fed Nrf2(+/+) mice. In livers of HF-fed mice, lo...
Background: The aim of this study was to evaluate the possible protective effect of sodium selenite on serum, liver, and kidney antioxidant enzymes activities in alloxan-induced type 1 diabetic rats. Methods: Forty Sprague-Dawley male rats were randomly divided into four groups; Group one as control, Group two as sham-treated with sodium selenite by 1 mg/kg intraperitoneal (i.p.) injections ...
