OBJECTIVES Typhoid fever is a dreadful disease of a major threat to public health in developing countries. Vaccination with bacterial immunodominant components such as surface proteins may prove as a potent alternative to live attenuated vaccines. InvH, an important part of needle complex in type three secretion system (TTSS) plays important role in efficient bacterial adherence and entry into ...

Malaria is a major global health problem for which an effective vaccine is required urgently. Prime-boost vaccination regimes involving plasmid DNA and recombinant modified vaccinia virus Ankara-encoding liver-stage malaria antigens have been shown to be powerfully immunogenic for T cells and capable of inducing partial protection against experimental malaria challenge in humans, manifested as ...

BACKGROUND Schitosomiasis japonica is still a significant public health problem in China. A protective vaccine for human or animal use represents an important strategy for long-term control of this disease. Due to the complex life cycle of schistosomes, different vaccine design approaches may be necessary, including polyvalent subunit vaccines. In this study, we constructed four chimeric protei...

The present investigation aims at assessing the hepatoprotective effect of triterpene fraction isolated from the stem bark of Wrightia tinctoria (containing lupeol, β-amyrin and β-sitosterol) on CCl4-induced hepatotoxicity in the rat. CCl4 (1.5 mg/kg, i.p) is a potent hepatotoxic agent which causes peroxidative degeneration of membrane lipids with the potential outcome of fatty degeneration. Th...

Bile acid homeostasis is tightly maintained through interactions between the liver, intestine, and kidney. During cholestasis, the liver is incapable of properly clearing bile acids from the circulation, and alternative excretory pathways are utilized. In obstructive cholestasis, urinary elimination is often increased, and this pathway is further enhanced after bile duct ligation in mice that a...

Fatty acid-binding proteins (FABPs) are cytosolic fatty acid chaperones that play a critical role in systemic regulation of lipid and glucose metabolism. In animals lacking the adipocyte/macrophage FABP isoforms aP2 and mal1, there is strong protection against diet-induced obesity, insulin resistance, type 2 diabetes, fatty liver disease, and hypercholesterolemic atherosclerosis. On high-fat di...

A solution hybridization/RNase protection assay with riboprobes was developed to quantitate apolipoprotein mRNA concentrations. Previously, radiolabeled DNA probes have been used in solution hybridization/S1 nuclease protection assays for this purpose. The new assay requires less time for probe preparation and hybridization compared to previous assays. In addition, the vector used for riboprobe...

the objective of the present study was to investigate the role of nanocarrier of magnetic isotope of 25-mg2+ (pmc16) in liver toxicity, atp content and oxidative stress due to malathion (mal) exposure. pmc16 nanoparticle were administered in different doses (0.05, 0.1 and 0.2 ld50) intravenously (iv) 40 minutes after a single mal (0.25 ld50= 207 mg/kg) intraperitoneal (ip) injection as a comple...

alcoholic liver disease (ald) is the main cause of chronic liver disease across the world and can lead to fibrosis and cirrhosis. the etiopathogenesis of ald is related to ethanol-induced oxidative stress, glutathione reduction, abnormal methionine metabolism, malnutrition, and production of endotoxins that activate kupffer cells. curcumin is an active ingredient of the rhizome of turmeric. the...

objective(s):non-alcoholic steatohepatitis (nash), is an important component of non-alcoholic fatty liver disease (nafld) spectrum, which progresses to the end stage liver disease, if not diagnosed and treated properly. the disproportionate production of pro- and anti-inflammatory adipokines secreted from fat contributes to the pathogenesis of nash. in this study, the comparative effect of piog...
