Bioluminescence tomography is a novel optical molecular imaging technology. The corresponding system, theory, and algorithmic frames have been set up. In the present study, we concentrated on the analysis of quantitative reconstruction deviation from peak-wavelength shift of luminescent source and the deviation of heterogeneous mouse model. The findings suggest that the reconstruction results are...
Methanolic extracts of different parts of Hyperium mysorense (HM) (Hypericaceae) namely aerial parts (HMA), flowering tops (HMF), leaf (HML), root (HMR) and stem (HMS) were screened for its in vitro and in vivo anti cancer activities. The short term toxicity studies were carried out against Ehrlich ascitic carcinoma (EAC) cells. Different concentrations of the HM extracts (1000 ??g/ml, 500 ??g/ml,...
A prototype small-animal X-ray micro computed tomography (muCT) system has been developed to screen laboratory small animals such as conchs, mice and rats. The muCTsystem consists of a flat-panel X-ray detector with a field-of-view of 130 x 130 mm , a microfocus X-ray source, a rotational C-arm bracket, a subject holder and a parallel data processing system. When the magnification ratio is 2, the...
Studies were conducted to establish the biochemical and pharmacological effects of W-2721 after irradiation in the mouse tests for up to 30 days of irradiation. Adult mice were irradiated with 3, 6, and 8 Gy of /sup 60/Co gamma rays with and without pretreatment by WR-2721 at a dose rate of 400 mg/kg body weight. Animals were sacrificed at different postirradiation days to estimate the amount of DNA,...
