Acute porphyria attacks are associated with the strong up-regulation of hepatic heme synthesis and over-production neurotoxic precursors. First-line therapy is based on carbohydrate loading. However, altered glucose homeostasis could affect its efficacy. Our first aim was to investigate prevalence insulin resistance (IR) in an observational case-control study including 44 Spanish patients acute...

Gastric cancer (GC) has a high rate of morbidity and mortality among various cancers worldwide. The development of noninvasive diagnostic methods or technologies for tracking the occurrence of GC is urgent, and searching reliable biomarkers is considered.This study intended to directly discover differential biomarkers from GC tissues by two-dimension-differential gel electrophoresis (2D-DIGE), ...

OBJECTIVE To investigate if serum apolipoprotein A-I and A-II (apoAI and apAII) concentrations change in subjects with systemic amyloidosis secondary to underlying disorders. METHODS Serum concentrations of apoAI and apoAII were measured in 21 multiple myeloma patients, including eight with amyloidosis; 95 rheumatoid arthritis patients, including 45 with amyloidosis; and 73 haemodialysis pati...

We examined the influence of zinc status on expression of certain transcription factors involved in regulation of apolipoprotein A-I (apoAI) expression in human hepatoblastoma Hep G2 cells. A low zinc basal medium (zinc deficient, ZD) consisting of DMEM and 10% Chelex100-treated fetal bovine serum was used to deplete cellular zinc over one passage. Cells were also cultured for one passage in me...

We (Wang H, Berschneider HM, Du J, and Black DD. Am J Physiol Gastrointest Liver Physiol 272: G935-G942, 1997; Wang H, Lu S, Du J, Yao Y, Berschneider HM, and Black DD. Am J Physiol Gastrointest Liver Physiol 280: G1137-G1144, 2001) previously showed that different fatty acids influence synthesis and secretion of triacylglycerol (TG) and phospholipid (PL) in a newborn swine enterocyte cell line...

BACKGROUND This study was designed to investigate the relation of a molecular analysis of apolipoprotein B (apoB)-containing atherogenic lipoprotein particles to coronary artery disease (CAD) in middle-aged men. METHODS AND RESULTS Two groups of men were studied. The first consisted of 97 patients with angiographically documented CAD (greater than 50% stenosis of at least one coronary artery)...
