High concentrations of plasma leptin and the release of pro-inflammatory cytokines in leptin-resistance in obesity have been reported to trigger endothelial dysfunction. The objective of this study was to elucidate the role of quercetin in modulating leptin-induced inflammation as assessed by the levels of Ob-Ra expression, ERK1/2 phosphorylation, NF-kappa(More)
BACKGROUND Uncoupling protein 2 (UCP2) gene polymorphisms have been reported as genetic risk factors for obesity and type 2 diabetes mellitus (T2DM). We examined the association of commonly observed UCP2 G(-866)A (rs659366) and Ala55Val (C > T) (rs660339) single nucleotide polymorphisms (SNPs) with obesity, high fasting plasma glucose, and serum lipids in a(More)
Facial plastic and reconstructive surgery often used skin graft on defects that cannot be covered primarily by a local flap. However, wound healing using skin graft is slow, most of the time the graft is contractured and the take of graft is not optimal. Platelet rich fibrin matrix (PRFM) is a new generation of concentrated platelets that produce natural(More)
A mtDNA A1555G base substitution in a highly conserved region of the 12S rRNA gene has been reported to be the main cause of aminoglycoside induced deafness. This mutation is found in approximately 3% of Japanese and 0.5-2.4% of European sensorineural deafness patients. We report a high prevalence (5.3%) of the A1555G mutation in sensorineural deafness(More)
Sensorineural deafness associated with increased sensitivity to aminoglycoside antibiotics as the consequence of an A1555G mutation in the mitochondrial DNA (mtDNA) in a highly conserved region of the small (12S) rRNA gene has been reported in Caucasian, Chinese, and Japanese individuals. We report here a large family of Balinese Indonesian origin with(More)
We have studied the genetic characteristics of a homopolymeric tract length heteroplasmy associated with the 16189C variant in the mtDNA D-loop control region to identify the factor(s) involved in the generation of the length heteroplasmy. The relative proportion of the various lengths of the polycytosines (i.e., the pattern of the length heteroplasmy) is(More)
We have investigated the genetics of the length heteroplasmy associated with the T16189C variant of mitochondrial DNA (mtDNA), and report here definitive evidence that the pattern of the length heteroplasmy is not simply the outcome of drift related to the random segregation of the mtDNA population during cell division, but is actively maintained and(More)
The unbound "free" bilirubin concentration (Bf), not the total bilirubin concentration, is the critical determinant of cellular uptake and toxicity of bilirubin. We compared Bf measured by a modified peroxidase method with published data obtained with ultrafiltration and examined conditions that affect the affinity (KF) of human (HSA) and bovine (BSA) serum(More)
The unbound, free concentration (Bf) of unconjugated bilirubin (UCB), and not the total UCB level, has been shown to correlate with bilirubin cytotoxicity, but the key molecular mechanisms accounting for the toxic effects of UCB are largely unknown. Mouse liver mitochondria increase unbound UCB oxidation, consequently increasing the apparent rate constant(More)
The concept of lactose intolerance has become embedded in Western medicine and developing economy medicine. It is based on evidence that intestinal lactase activity persists into later childhood and throughout life in only a minority of the world's population, notably northern European-derived populations. These people have the T single nucleotide(More)
