Inhibition of the MDM2–p53 interaction has been becomes a new therapeutic strategy to activate wild-type p53 in tumors. Molecular dynamics (MD) simulations were used to study the effects of quercetin and taxifolin on MDM2–p53 complex. We found that binding of ligands (quercetin and taxifolin) led to the dissociation of MDM2–p53 complex. Analyses of the(More)
Azadirachta indica leaves indicated the presence of active principles with proven antioxidants, antiinflammatory, immunomodulatory, free radical scavenging and healing properties. In the present study we evaluated the healing effects of 50% ethanol extract of dried leaves of Azadirachta indica on trinitrobenzene sulfonic acid-induced colitis in rats.(More)
The present study has evaluated the healing effects of extract of dried fruit pulp of Terminalia chebula (TCE) on acetic acid (AA)-induced colitis in rats. TCE (600 mg/kg) showed healing effects against AA-induced colonic damage score and weight when administered orally daily for 14 days. TCE was further studied for its effects on various physical(More)
BACKGROUND The aim of this multicentric prospective study in India was to assess the performance of the QuantiFERON TB-Gold in tube (QFT-GIT), Tuberculin Skin Test (TST) and microbiological results as additional tools for diagnosing active tuberculosis (TB) and latent infection (LTBI) according to Human Immunodeficiency Virus (HIV) status. METHODS(More)
The global area under brinjal cultivation is expected to be 1.85 million hectare with total fruit production about 32 million metric tons (MTs). Brinjal cultivars are susceptible to a variety of stresses that significantly limit productivity. The most important biotic stress is caused by the Brinjal fruit and shoot Borer (FSB) forcing farmers to deploy high(More)
BACKGROUND The aim of this multicentric prospective study in India was to assess the value of several microbiological tools that contribute to the diagnosis of tuberculosis (TB) according to HIV status. METHODS Standard microbiological tools on individual specimens were analyzed. RESULTS Among the 807 patients with active TB, 131 were HIV-infected, 316(More)
To elucidate whether the transgenic crop alters the rhizospheric bacterial community structure, a 2-year study was performed with Cry1Ac gene-inserted brinjal crop (Bt) and their near isogenic non-transformed trait (non-Bt). The event of Bt crop (VRBT-8) was screened using an insect bioassay and enzyme-linked immunosorbent assay. Soil moisture, NH4 +-N, NO3(More)
Cry protein expressing insect-resistant trait is mostly deployed to control major devastating pests and minimize reliance on the conventional pesticides. However, the ethical and environmental issues are the major constraints in their acceptance, and consequently, the cultivation of genetically modified (GM) crops has invited intense debate. Since root(More)
The study incorporates the wound healing potential of Aegle marmelos fruit pulp extract (AME) on excision, incision, and dead space wound models in rats. AME (200 mg/kg) was administered orally once daily for variable days depending on the type of wound ulcer study. AME was studied for its wound breaking strength (incision wound), rate of contraction,(More)
The intracellular cobalt-type nitrile hydratase was purified from the bacterium Rhodococcus erythropolis. The pure enzyme consisted of two subunits of 29 and 30 kDa. The molecular weight of the native enzyme was estimated to be 65 kDa. At 25 °C the enzyme had a half-life of 25 h. The Michaelis–Menten constants K m and v max for the enzyme were 0.624 mM and(More)
