Most of methylxanthine derivatives including caffeine have been known to radiosensitize cancer cells, but the obstacles such as toxicity, request of high dose and poor solubility hinder their preclinical evaluations and clinical applications. In this study, we evaluated the efficacy

Blood flow to contracting muscles is increased rapidly and is redistributed within the muscle. Recent research has highlighted that insulin causes similar changes, but these are absent in insulin resistance, resulting in impaired insulin-mediated muscle glucose uptake. Understanding the mechanisms

Exercise and insulin increase muscle glucose uptake by different mechanisms and also increase capillary recruitment, which is proposed to facilitate access for hormones and nutrients. The genetically obese Zucker rat shows impaired insulin- but not contraction-mediated glucose uptake in muscle.

To determine the efficacy of a caffeine derivative 1-methylxanthine (1-MTX) in increasing radiosensitivity of cancer cells and elucidate the underlying mechanisms in vitro. RKO human colorectal cancer cells carrying wild type protein 53 kDa (p53) were incubated with 3 mM

A comparative study of N-acetyltransferase 2 (NAT2) genotyping and phenotyping (caffeine test method) was performed on 211 persons to elucidate apparent discrepancies in the assignment of NAT2*12 and NAT2*13 alleles which occur in the literature. The study used the standard
