Proper vascular function is important for well-being of mother and growing fetus. VEGF, and VEGF levels and its vascular endothelial complications in gestational diabetes mellitus (GDM) together with the association of inflammation and advanced glycation end products (AGEs) are less studied. VEGF/VEGF (VEGF RATIO) in GDM pregnant women was investigated in this study.

Background: Single nucleotide polymorphisms (SNPs) in lipoprotein lipase gene () have been shown to influence metabolism related to lipid phenotypes. Dietary factors have been shown to modify the association between SNPs and lipids; however, to date, there are no studies in South Asians. Hence, we tested for the association of four common SNPs with plasma lipids and examined the interactions between the SNPs and dietary factors on lipids in 1,845 Asian Indians.

Activation of the IL-6 mediated JAK-STAT (Janus associated kinase-signal transducer and activator of transcription) oncogenic signalling plays a major role in hepatocellular carcinoma pathogenesis. The aim of this study is to assess the anti-tumour, anti-proliferative and apoptotic potential of artesunate and its capacity to modulate JAK-STAT pathway in a nitrosodiethylamine mediated experimental hepatocellular carcinoma model. Administration of nitrosodiethylamine (200mg/kg body weight by i.

Dietary agents and phytochemicals have been utilised for the management of cancer for many years. Hesperetin, a dietary flavonoid found abundantly in citrus fruits, was evaluated for its cytotoxic and pro-apoptotic activities in A431 human skin carcinoma cells. Effect of hesperetin in regulating MAPK (Mitogen-Activated Protein Kinase) signalling pathway and levels of various cyclins and other downstream apoptotic proteins were investigated.

Objective: To investigate the genetic association of eight variants of the adiponectin gene with type 2 diabetes mellitus (T2DM), obesity and serum adiponectin level in the south Indian population.

Methods: The study comprised of 1100 normal glucose tolerant (NGT) and 1100 type 2 diabetic, unrelated subjects randomly selected from the Chennai Urban Rural Epidemiology Study (CURES), in southern India. Fasting serum adiponectin levels were measured by radioimmunoassay.
