(SPRINGER, 2012-05)The protective effect of taurine against doxorubicin-induced testicular oxidative stress and apoptosis was investigated in rats. Male rats 8 weeks of age were treated with doxorubicin alone (3 mg/kg, i.p. every other day ... -
Expeditious reaction of ninhydrin with active methylene compounds on montmorillonite K10 clay
(SPRINGER WIEN, 2009-02)Ninhydrin reacted expeditiously with thirteen active methylene compounds on montmorillonite K10 clay at room temperature to furnish, in 5 min, a Knoevenagel condensate in one case, aldols in six cases, aldol-derived cyclic ... -
Relaxor behaviour of (Ba0⋅5Sr0⋅5)(Ti0⋅6Zr0⋅4)O3 ceramics
(Indian Academy of Sciences, 2008-11-01)Ba0⋅5Sr0⋅5Ti0⋅6Zr0⋅4O3 ceramic has been prepared through solid state reaction route. X-ray diffraction shows that the sample has cubic perovskite structure with space group Pm–3m at room temperature. Temperature dependent ... -
Inactivation of indispensable bacterial proteins by early proteins of bacteriophages: Implication in antibacterial drug discovery
(BENTHAM SCIENCE PUBL LTD, 2008-06)Bacteriophages utilize host bacterial cellular machineries for their own reproduction and completion of life cycles. The early proteins that phage synthesize immediately after the entry of their genomes into bacterial cells ... -
Taurine plays a beneficial role against cadmium-induced oxidative renal dysfunction
(SPRINGER, 2009-03)The present study has been carried out to investigate the role of taurine (2-aminoethanesulfonic acid), a conditionally essential amino acid, in ameliorating cadmium-induced renal dysfunctions in mice. Cadmium chloride ... -
Protective role of arjunolic acid in response to streptozotocin-induced type-I diabetes via the mitochondrial dependent and independent pathways
(ELSEVIER IRELAND, 2009-03-04)Increasing evidences in both experimental and clinical studies suggest that oxidative stress is involved in the pathogenesis of diabetic tissue damage. Pancreatic P-cell death is the cause of decreased insulin production ... -
The delayed early gene G23 of temperate mycobacteriophage L1 regulates the expression of deoxyribonuclease, the product of another delayed early gene of the phage
(POLSKIE TOWARZYSTWO MIKROBIOLOGOW-POLISH SOCIETY OF MICROBIOLOGISTS, 2008)To get clues about the genes as well as the gene regulatory circuit controlling the lytic development of temperate mycobacteriophage L1, previously we screened several conditional lethal mutants of L1 and characterized ... -
