– According to pharmacopeia, unopened insulin vials must be stored in a refrigerator (2–8 °C) while storage at ambient temperature (25–28 is usually permitted for the 4-week usage period during treatment– The authors investigated whether remains stable and retains biological activity oscillating tropical temperatures– They found that structure of its efficiency on receptor Akt phosphorylation h...

Hepatic glucose production and relative Krebs cycle fluxes (indexed to a citrate synthase flux of 1.0) were evaluated with [U-(13)C]glycerol tracer in 5 fed healthy controls and 5 Type 1a glycogen storage disease (GSD1a) patients. Plasma glucose, hepatic glucose-6-phosphate (G6P) and glutamine (13)C-isotopomers were analyzed by (13)C NMR via blood sampling and chemical biopsy. In healthy subjec...

background the fas receptor/ligand system including soluble forms is the most important apoptotic initiator in the liver. dysregulation of this pathway may contribute to abnormal cell proliferation and cell death and is regarded as one of the mechanisms preventing the immune system from rejecting the tumor cells. objectives to analyze the role of fas system fas/ fas ligand (fas/ fasl) in the mu...

BACKGROUND In chronic hepatitis C, the fibrosis progression rates are extremely variable and can be influenced by factors associated with the host, virus and environment. Among the associated metabolic factors, hepatic steatosis is characterized by an accumulation of triglycerides in hepatocytes. In the host, genetic determinants of hepatic steatosis are observed, such as single-nucleotide poly...

Rats artificially selected over several generations for high intrinsic endurance/aerobic capacity resulting in high capacity runners (HCR) has been developed to study the links between high aerobic fitness and protection from metabolic diseases (Wisloff et al., Science, 2005). We have previously shown that the HCR strain have elevated hepatic mitochondrial content and oxidative capacity. In thi...

Genotype phenotype correlations in Wilson disease (WD) are best established in homozygous patients or in compound heterozygous patients carrying the same set of mutations. We determined the clinical phenotype of patients with WD carrying the c.2298_2299insC in Exon 8 (c.2299insC) or the p. Ala1003Thr missense substitution in Exon 13 mutations in the homozygous or compound heterozygous state. We...

Excessive production of collagen type I is a major contributor to hepatic fibrosis. Activated (myofibroblastic), but not quiescent, hepatic stellate cells (lipocytes) have a high level of collagen type I and a-smooth muscle actin expression. Therefore, stellate cell activation is a critical step in hepatic fibrosis. Here we show that quiescent stellate cells were activated by the generation of ...
