Atopic dermatitis causes lipid accumulation in the liver of NC/Nga mouse.

Various factors have been reported to influence lipid metabolism and cause metabolic syndrome. However, the influence of allergy on the liver that plays important role of lipid metabolism has not been clarified. The aim of this study was to examine the influence of allergy on lipid metabolism of liver.

Continuous intake of a high-fat diet beyond one generation promotes lipid accumulation in liver and white adipose tissue of female mice.

Lipid metabolism in a child may be altered when the mother has a high-fat diet (HFD), but it is unclear whether the lipid metabolism of future offspring (grandchildren) is also changed under these circumstances. In this study, we examined the influence of intake of an HFD beyond one generation on offspring in normal mice. Parent mice fed an HFD were bred and the resultant second and third generations were also fed an HFD.

Increased monocytic adhesion by senescence in human umbilical vein endothelial cells.

We investigated whether replicative senescence of endothelial cells contributed to the pathogenesis of atherosclerosis in human umbilical vein endothelial cells (HUVECs). HUVECs at a population-doubling level of 30 (PDL30) divided much more slowly than those at PDL9. The percentage of SA-β-Gal-positive cells and the mRNA expression levels of PAI-1 and p21 at PDL30 were significantly higher than those at PDL9.

Epidemiology of bacteremia and factors associated with multi-drug-resistant gram-negative bacteremia in hematopoietic stem cell transplant recipients.

The incidence of Gram-negative bacteremia has increased in hematopoietic stem cell transplant (HSCT) recipients. We prospectively collected data from 13 Brazilian HSCT centers to characterize the epidemiology of bacteremia occurring early post transplant, and to identify factors associated with infection due to multi-drug-resistant (MDR) Gram-negative isolates. MDR was defined as an isolate with resistance to at least two of the following: third- or fourth-generation cephalosporins, carbapenems or piperacillin-tazobactam.
