Resveratrol is a polyphenol abundantly found in red grape skin and is effective against antiaging and anti-inflammation associated with immune responses. In this study, we have investigated the effect of resveratrol on skin lesion, high mobility group box (HMGB)1 and inflammation pathway in an atopic dermatitis (AD) mouse model. AD-like lesion was induced(More)
Polyphenolic compound tannic acid, which is mainly found in grapes and green tea, is a potent antioxidant with anticarcinogenic activities. In this present study, we hypothesized that tannic acid could inhibit nuclear factor (NF)κB signaling and inflammation in atopic dermatitis (AD) NC/Nga mice. We have analyzed the effects of tannic acid on dermatitis(More)
There is a definite cardioprotective role for 14-3-3η protein against pressure overload induced cardiac hypertrophy and streptozotocin induced cardiac dysfunction in type 1 diabetes mellitus (DM). But it is not conclusive whether it has any influence on mitochondrial mediated cardiomyocyte apoptosis in type 2 DM. In order to test this hypothesis, we have(More)
Quercetin, glycosylated form of flavonoid compound, has potent antioxidant and anti-inflammatory properties. In this study, we have investigated the effects of quercetin on skin lesion, high-mobility group box (HMGB)1 cascade signalling and inflammation in atopic dermatitis (AD) mouse model. AD-like lesion was induced by the application of house dust mite(More)
Nephropathy is one of the complications of diabetes mellitus in human and experimental animals. There are various pathological renal remodeling processes leading to diabetic nephropathy because of the chronic hyperglycemia during diabetes mellitus. Various reports suggest the involvement of oxidative stress, inflammation and fibrosis during this(More)
We investigated the effect of curcumin on liver injury in diabetic rats induced by streptozotocin (STZ) through modulation of endoplasmic reticulum stress (ERS) and unfolded protein response (UPR). Experimental diabetes was induced by a single intraperitoneal injection of STZ (55 mg/kg), and curcumin was given at 100 mg/kg by gavage for 56 days. We observed(More)
The renin angiotensin system (RAS) is essential for the regulation of cardiovascular and renal functions to maintain the fluid and electrolyte homeostasis. Recent studies have demonstrated a locally expressed RAS in various tissues of mammals, which is having pathophysiological roles in those organ system. Interestingly, local RAS has important role during(More)
Curcumin, a phenolic compound, has a wide spectrum of therapeutic effects such as antitumor, anti-inflammatory, anti-cancer and so on. The study aimed to investigate the underlying mechanisms of curcumin to protect liver damage and progression of non-alcoholic steatohepatitis (NASH) in a novel NASH-hepatocellular carcinoma (HCC) mouse model. To induce this(More)
OBJECTIVE Fasting (48h) in mice causes resistance to insulin-induced hypoglycemic seizures (IIHS) but in rats fasting (14-16h) predisposes IIHS. So we suspect the duration of fasting may possibly affect the onset of seizures and in this study, we investigated the IIHS by administering 8 Units (U) insulin (INS)/k.g., intraperitoneally to 8 weeks old male(More)
Le Carbone (LC) is a charcoal supplement, which contains a large amount of dietary fibers. Several studies suggested that charcoal supplement may be beneficial for stomach disorders, diarrhea, gas and indigestion. But no studies address whether LC intake would suppress inflammation, cell proliferation or disease progression in colitis. In the present study,(More)
