BACKGROUND Tissue factor (TF) is the main initiator of the arterial blood coagulation system, and aggregated LDL (agLDL) are found in the arterial intima. Our hypothesis is that agLDL internalization by vascular smooth muscle cells (VSMCs) may trigger TF-procoagulant activity. METHODS AND RESULTS Cultured human VSMCs were obtained from human coronary arteries of explanted hearts during transp...

Mir, P. S., Bittman, S., Hunt, D., Entz, T. and Yip, B. 2006. Lipid content and fatty acid composition of grasses sampled on different dates through the early part of the growing season. Can. J. Anim. Sci. 86: 279–290. In order to explore the value of herbage for the production of ruminant products with a high content of conjugated linoleic acid (CLA), a study was undertaken to determine the co...

The characteristics of manganese and iron binding to human apotransferrin (apo-tf) have been investigated and compared in this study. Both metal ions were taken up by human apo-tf and formed complexes, with the maximum absorbances observed at 410 and 340 nm for manganese-transferrin (Mn-tf) and 465 nm for iron-transferrin (Fe-tf). Addition of manganese (1.5 µg/ml) to the reaction mixture contai...

Coxiella burnetii is an obligate intracellular pathogen and the causative agent of human Q fever. Replication of the bacterium within a large parasitophorous vacuole (PV) resembling a host phagolysosome is required for pathogenesis. PV biogenesis is a pathogen driven process that requires engagement of several host cell vesicular trafficking pathways to acquire vacuole components. The goal of t...

A poorly understood factor that may influence differences in the accumulation of a xenobiotic among fishes is interspecies differences in physiology. We have extensively studied the uptake, distribution, and excretion kinetics of the lipophilic herbicide trifluralin (TF) in fish, using a static water exposure system and compartmental toxicokinetic models. We obtained quantitative estimates of p...

Phosphatidylcholine transfer protein (Pc-tp) is a highly specific carrier of phosphatidylcholine (PC) without known function. Proposed functions include the supply of PC required for secretion into bile or lung air space (surfactant) and the facilitation of enzymatic reactions involving PC synthesis or breakdown. To test these functions, we generated knock-out mice unable to make Pc-tp. Remarka...

brain death is associated with increased inflammatory cytokines levels and poor graft quality to transplant. we aimed to evaluate the impact of ascorbic acid (aa) on the inflammatory status of brain-dead donors (bdds). forty bdds were randomly divided into two groups. donor treatment (n=20) consisted of 100 mg/kg aa infusion 6 hours before donor operation and subsequent infusion of 100 mg/kg/p6...

Malnutrition occurs when the supply of available nutrients is less than organic demand. It an underdiagnosed problem in veterinary medicine and can result several negative metabolic consequences, with greater morbidity mortality. Currently, classification nutritional status (NS) performed subjectively medicine, so studies discoveries about laboratory markers (objectives) malnutrition are desira...
