We introduce the use of a hydroborated polyisoprene (PIP) macroinitiator for the rapid surface-initiated growth of superhydrophobic polymethylene (PM) films. Rinsing of a dip-coated PIP film on a methyl-terminated surface atop silicon or gold substrates results in robustly bound, isolated PIP clusters. After hydroboration of the internal olefins, these clusters result in extremely rapid growth ...

The major protein constituent of amyloid deposits in Alzheimer’s disease is the â-peptide, which in solution can fold as a random coil, monomeric R-helix, or oligomeric â-sheet structure, the latter structure being toxic and eventually precipitating as amyloid. In this report, using circular dichroism and nuclear magnetic resonance spectroscopic techniques, we demonstrate that in micelle soluti...

Dietary intervention to prevent colon cancer is a major health issue. At present it is not clear which dietary factors modify colon cancer risk. Caloric restriction reduces the incidence of many spontaneous and car cinogen-induced tumors in rodents, but its role in human carcinogenesis is unknown. The relationships of body mass index (BMI), body composition, and resting metabolic rate (RMR) to ...

size quantitative differences between normal and malignant cells in terms of rates of enzyme synthesis and release. There have been relatively few reports that have dealt specifically with the question of whether neoplastic transformation is as sociated with qualitative differences in the type of plasminogen activator that is synthesized. This is an important consideration since it is well esta...

Lactococcus lactis â-phosphoglucomutase (â-PGM) catalyzes the interconversion of â-D-glucose 1-phosphate (â-G1P) and â-D-glucose 6-phosphate (G6P), forming â-D-glucose 1,6-(bis)phosphate (âG16P) as an intermediate. â-PGM conserves the core domain catalytic scaffold of the phosphatase branch of the HAD (haloalkanoic acid dehalogenase) enzyme superfamily, yet it has evolved to function as a mutas...

Peroxidase metabolism of 2-amino-4-(5-nitro-2-fiiryl)thiazole (ANFI") was evaluated in vitro and in rivo. IH vitro metabolism of ANFT was characteristic of the hydroperoxidase activity of prostaglandin H synthase. The peroxidase inhibitors, 6-n-propyl-2-thiouracil and methimazole, significantly reduced ANFT binding to trichloroacetic acid precipitable material and glutathione conjugate formatio...
