Active cellular preform derived from stems of jute and sticks of cane and their suitability for bulk porous Si/SiC ceramics
(SPRINGER, 2009-04)Stems of Jute (Corchorus capsularis L.) and sticks of Cane (Calamus rotang L.), plants of immense economic importance in the Indian subcontinent, were converted into carbonaceous perform (C-preform) maintaining the circular ... -
Aqueous extract of the bark of Terminalia arjuna plays a protective role against sodium-fluoride-induced hepatic and renal oxidative stress
(SPRINGER TOKYO, 2007)Fluoride is an environmental and industrial pollutant. It has already been reported that the accumulation of fluoride can alter the activities of some enzymes involved in the free-radical metabolism and also decrease the ... -
Reply to "comment on 'Quantum time-of-flight distribution for cold trapped atomsa'"
(AMER PHYSICAL SOC, 2008-02-22)In their comment Gomes [Phys. Rev. A 77, 026101 (2008)] have questioned the possibility of empirically testable differences existing between the semiclassical time of flight distribution for cold trapped atoms and a quantum ... -
A 43 kD protein from the herb, Cajanus indicus L., protects against fluoride induced oxidative stress in mice erythrocytes
(ELSEVIER, 2007-05-31)Present study has been carried out to evaluate the protective and curative roles of a 43 kD protein isolated from the herb Cajanus indicus L. on sodium fluoride (NaF) induced toxicity in mice erythrocytes. In the preventive ... -
Characterization of differential ripening pattern in association with ethylene biosynthesis in the fruits of five naturally occurring banana cultivars and detection of a GCC-box-specific DNA-binding protein
(SPRINGER, 2008-07)MA-ACS1 and MA-ACO1 are the two major ripening genes in banana and play crucial role in the regulation of ethylene production during ripening. Here, we report a comparative ripening pattern in five different naturally ... -
Aspects of nonideal Stern-Gerlach experiment and testable ramifications
(IOP PUBLISHING LTD, 2007-11-16)We critically examine the quantum-mechanical modelling of a measurement process using the Stern-Gerlach (SG) setup in the most general context, probing in particular for nonideal situations, the subtleties involved in the ... -
Amelioration of galactosamine-induced nephrotoxicity by a protein isolated from the leaves of the herb, Cajanus indicus L.
(ELSEVIER, 2007-04-25)BACKGROUND: Galactosamine (GalN), an established experimental toxin, mainly causes liver injury via the generation of free radicals and depletion of UTP nucleotides. Renal failure is often associated with end stage liver ... -
Comparative physiological and molecular responses of a common aromatic indica rice cultivar to high salinity with non-aromatic indica rice cultivars
(SPRINGER, 2008-08)In an attempt to understand the molecular basis of salt-stress response in the aromatic rice Gobindobhog, a comprehensive analysis encompassing physiological or biochemical assays and gene expression studies under high ... -
Entanglement and fidelity signatures of quantum phase transitions in spin liquid models
(AMER PHYSICAL SOC, 2008-03-01)We consider a spin ladder model which is known to have matrix product states as exact ground states with spin liquid characteristics. The model has two critical-point transitions at the parameter values u=0 and. We study ... -
The p53-MDM2 network: From oscillations to apoptosis
(INDIAN ACAD SCIENCES,, 2007-08-01)The p53 protein is well-known for its tumour suppressor function. The p53-MDM2 negative feedback loop constitutes the core module of a network of regulatory interactions activated under cellular stress. In normal cells, ... -
Protection of arsenic-induced hepatic disorder by arjunolic acid
(BLACKWELL, 2007-11)Arsenic is one of the ubiquitous environmental pollutants, which affects nearly all organ systems. The present study has been carried out to investigate the hepatoprotective role of arjunolic acid, a triterpenoid saponin, ... -
A 43 kD protein isolated from the herb Cajanus indicus L attenuates sodium fluoride-induced hepatic and renal disorders in vivo
(SPRINGER, 2007-05-31)The herb, Cajanus indicus L, is well known for its hepatoprotective action. A 43 kD protein has been isolated, purified and partially sequenced from the leaves of this herb. A number of in vivo and in vitro studies carried ... -
GENE EXPRESSION IS NOISY
(Indian Science News Association, 2007-04-01)Gene expression, leading to protein synthesis, involves biochemical events which are probabilistic in nature. The stochastic effects are prominent when the number of participating molecules is small or the transitions ... -
Attenuation of acetaminophen-induced hepatotoxicity in vivo and in vitro by a 43-kD protein isolated from the herb Cajanus indicus L
