21 21 In view of evidence that Zn neurotoxicity contributes to some forms of pathological neuronal death, we developed a model of Zn neurotoxicity in a cell line amenable to genetic manipulations. Exposure to 500 mM ZnCl for 15 min under depolarizing conditions 2 21 resulted in modest levels of PC12 cell death, that was reduced by the L-type Ca channel antagonist, nimodipine, and increased by t...

The experiment described here studied the rat motor activity pattern as a function of the photoperiod of circadian light-dark cycles in the limits of entrainment (22-and 23-h periods). In most cases, the overt rhythm showed 2 circadian components: 1 that followed the external LD cycle and a 2nd rhythm that was free run. The expression of these components was directly dependent on the photoperio...

Normal human urothelium and tumors of urothelial origin were analyzed with a panel of seven mouse monoclonal antibodies that identify surface antigens of cultured bladder cancer cell lines. Three categories of antigens were defined on the basis of differential expression on normal urothelium versus bladder tumors. Om5 (a category 1 antigen) is a highly restricted, differentiation antigen detect...

A pot experiment was conducted to evaluate the effect of kitchen waste compost (KWC) and NPK fertilizers on growth yield tomato. It laid out in a completely randomized block design (CRBD) using 25 treatments having 3 replications each. Agronomic parameters tomato were recorded at 15, 30, 45, 60 days interval. The highest parameter found with days. tallest plant height (57 cm) T13(N120P60K80 kg ...

We discuss neutrino masses in the framework of a minimal extension of the minimal supersymmetric standard model (MSSM) consisting of an additional single righthanded neutrino superfield N with a heavy Majorana mass M , which induces a single light see-saw mass mν3 leaving two neutrinos massless at tree-level. This trivial extension to the MSSM may account for the atomospheric neutrino data via ...

The entrainment limits of the circadian rhythms of feeding activity were studied in Wistar rats exposed to gradually increasing and decreasing or to static light-dark cycles. In the former, the entrainment limits of feeding behavior were 22 h 10 min and 26 h 40 min. In the latter, the upper limit was higher, because rats under zeitgeber period ( t) length = 27 h ( t27) and t28 met the criteria ...
