Syzygium cumini L. is widely used for the treatment of diabetes in various parts of India. The protective efficacy of S. cumini seed extract (SCE) against peroxidative damage contributing to skin carcinogenesis in Swiss albino mice was tested in the present study. A single topical application of 7,12-dimethyl benz(a)anthracene (100 microg/100 microl acetone), followed 2 weeks later by repeated ...

Ethylene oxide (EtO), a potent monofunctional DNA alkylating agent, has been shown to induce sister chromatid exchanges (SCE) in the peripheral blood lymphocytes of animals and workers exposed to it in vivo. We have previously reported that elevations of SCE persist for 6 years after cessation of EtO exposure in cynomolgus monkeys chronically exposed to EtO; the elevation in mean SCE was entire...

Color characteristics of the shades for different filler type resin composites were compared in the reflectance and transmittance modes, and specular component included (SCI) and specular component excluded (SCE) geometries for reflectance mode. Resin composites and shades used in this study were submicron filled Estelite Sigma (Sigma: Inc, A2, A3, B3, C2, OA2, OA3) and nanofilled Filtek(TM) Su...

The present studies were designed to evaluate the role of cell cycle time and time of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) administration on the persistence of sister chromatid exchange (SCE)-inducing lesions in normal and lymphoma second- and third-division AKR bone marrow cells. Normal second-division cells harvested from mice given injections of BCNU at the start of an 18-, 24-, or 28...

We propose to bring together two conceptually complementary ideas: (1) selfcon…rming equilibrium (SCE): at rest points of learning dynamics in a game played recurrently, agents best respond to con…rmed beliefs, i.e., beliefs consistent with the evidence they accumulated, and (2) ambiguity aversion: agents, other things being equal, prefer to bet on events with known rather than unknown probabil...

Oxygen reducing biocathodes were formed from sludge under constant polarization at -0.2 and +0.4V/SCE. Under chronoamperometry at pH10.3 ± 0.3, current densities of 0.21 ± 0.03 and 0.12 ± 0.01 Am(-2) were displayed at -0.2V/SCE by the biocathodes formed at -0.2 and 0.4V/SCE, respectively. Voltammetry revealed similar general characteristics for all biocathodes and higher diffusion-limited curre...

This paper discusses some applications of statistical condition estimation (SCE) to the problem of solving linear systems. Specifically, triangular and bidiagonal matrices are studied in some detail as typical of structured matrices. Such a structure, when properly respected, leads to condition estimates that are much less conservative compared with traditional non-statistical methods of condit...

The study is designed to find out the biochemical basis of antidiabetic property of Symplocos cochinchinensis (SC), the main ingredient of 'Nisakathakadi' an Ayurvedic decoction for diabetes. Since diabetes is a multifactorial disease, ethanolic extract of the bark (SCE) and its fractions (hexane, dichloromethane, ethyl acetate and 90% ethanol) were evaluated by in vitro methods against multipl...

Chemopreventive effects of green tea and coffee among cigarette smokers were examined in 52 clinically healthy male subjects between 20 and 52 years of age. Blood specimens were obtained from nonsmokers (group I), smokers (group II), smokers consuming green tea (group III), and smokers drinking coffee (group IV). The mean number of cigarette smoking years (> 10 cigarettes/day) in groups II-IV r...
