Increasing evidence suggests that oxidative stress is involved in the pathogenesis of diabetic nephropathy (DN) and this can be attenuated by antioxidants. D-Saccharic acid 1,4-lactone (DSL) is known for its detoxifying and antioxidant properties. Our early investigation showed that DSL can ameliorate alloxan (ALX) induced diabetes mellitus and oxidative(More)
Kombucha, a fermented tea (KT) is claimed to possess many beneficial properties. Recent studies have suggested that KT prevents paracetamol and carbon tetrachloride-induced hepatotoxicity. We investigated the beneficial role of KT was against tertiary butyl hydroperoxide (TBHP) induced cytotoxicity and cell death in murine hepatocytes. TBHP is a well known(More)
The present study investigated the role of D-saccharic acid 1,4-lactone (DSL) in the spleen tissue of alloxan (ALX) induced diabetic rats. Diabetes was induced in rats by injecting ALX (at a dose of 120 mg/kg body weight) intraperitoneally in sterile normal saline. Elevated levels of blood glucose, glycosylated Hb and TNFα decreased levels of plasma insulin(More)
Oxidative stress plays a vital role in diabetic complications. To suppress the oxidative stress mediated damage in diabetic pathophysiology, a special focus has been given on naturally occurring antioxidants present in normal diet. D-saccharic acid 1,4-lactone (DSL), a derivative of D-glucaric acid, is present in many dietary plants and is known for its(More)
Sustained hyperglycemia and increased oxidative stress play major roles in the development of secondary complications in diabetes including liver injury. Dietary supplement of antioxidants is effective in preventing oxidative stress mediated tissue damage in diabetic pathophysiology. D-Saccharic acid 1,4-lactone (DSL), a derivative of D-glucaric acid, is(More)
Kombucha (KT), a fermented black tea (BT), is known to have many beneficial properties. In the present study, antioxidant property of KT has been investigated against tertiary butyl hydroperoxide (TBHP) induced cytotoxicity using murine hepatocytes. TBHP, a reactive oxygen species inducer, causes oxidative stress resulting in organ pathophysiology. Exposure(More)
Diabetic complications associated with increased oxidative stress can be suppressed by antioxidants. In the present study we investigated the antidiabetic and antioxidant effects of Kombucha (KT), a fermented black tea, in comparison to that of unfermented black tea (BT), in ALX-induced diabetic rats. ALX exposure lowered the body weight and plasma insulin(More)
Kombucha tea, a non-alcoholic beverage, is acquiring significant interest due to its claimed beneficial properties. The microbial community of Kombucha tea consists of bacteria and yeast which thrive in two mutually non-exclusive compartments: the soup or the beverage and the biofilm floating on it. The microbial community and the biochemical properties of(More)
D-Saccharic acid 1,4-lactone (DSL) is a derivative of D-glucaric acid. It is a beta-glucuronidase inhibitor and possesses anticarcinogenic, detoxifying, and antioxidant properties. In the present study, the protective effects of DSL were investigated against tertiary butyl hydroperoxide (TBHP) induced cytotoxicity and cell death in vitro using murine(More)
This study reports the identification of a chitin deacetylase gene in Cryptococcus laurentii strain RY1 over-expressing under nitrogen limitation by differential display. The up-regulation took place in robustly growing cells rather than in starving quiescent autophagic cells. Quantitative Real Time-PCR, enzyme activity in cell lysate and cell wall analysis(More)
