Cystone, a polyherbal Ayurvedic preparation, was found to protect rats partially but significantly against cisplatin-induced renal toxicity, when given intraperitoneally 1 hour before cisplatin. At 500 and 1000 μg/ml, it also inhibited lipid peroxidation induced by cisplatin in renal cortical slices by 62.7 and 71.6% respectively. The rats pretreated with Cystone (1000 mg/kg i.p.) had significa...

V. G. Berkovich’s Non-Archimedean analytic geometry provides a natural framework to understand the combinatorial aspects in the theory of toric varities and toroidal embeddings. This point of view leads to a conceptual and elementary proof of the following result : if X is an algebraic scheme over a perfect field and if D is the exceptional normal crossing divisor of a resolution of the singula...

(December 1998) UM-P-98/62 RCHEP-98/18 Mirror matter and primordial black holes

Implicit in most discussions concerning the evaporation of primordial black holes (PBHs) is the assumption that the only particles produced are those which interact with the particles in the standard model. However there may exist particles which are singlets under the standard model gauge group and whose only interaction with ordinary matter is gravitational. It has been pointed out in ref. [1...
