sepsis/triacylglycerol

BACKGROUND The overall fatty acid (FA) composition, and especially proportions of n-6 and n-3 polyunsaturated fatty acids in plasma and membrane lipids, greatly impacts on cell and organ functions as well as on many biological processes. METHODS Polyunsaturated FA determine membrane fluidity and

Cytokines seem to play an important role in the metabolic disturbances that are commonly associated with sepsis. In this study, we analyzed the effect of tumor necrosis factor, interleukin-1 and interleukin-6, as well as that of tumor necrosis factor in combination with interleukin-1 or

The aim of this study was to evaluate the effect of a gram-negative bacteria sepsis on the activity of the enzymes lipoprotein lipase (LPL) and hepatic lipase (HL), involved in the clearance of circulating triacylglycerol-rich fat particles. Fasting rats were intravenously injected with NaCl9 g.l-1,

OBJECTIVE To investigate the effect of tumour necrosis factor-alpha (TNF-alpha) and other sepsis related cytokines on the synthesis of several lipid fractions by human hepatocytes. METHODS Laboratory study. METHODS University departments of surgery and biochemistry. METHODS Livers from eight donors

1. Administration of tumour necrosis factor (cachectin) and of interleukin-1-alpha increased the plasma level of nonesterified fatty acids in fed rats, and in the case of interleukin-1-alpha the blood glycerol level was also increased, suggesting stimulation of adipose tissue lipolysis. There were

Human neutrophils incubated for 1 h in vitro with 10% commercial pooled, human serum containing high levels of free fatty acids (1141 microM) displayed a distinct lipid signal, typical of triacylglycerol, in the 1H NMR spectrum. Concurrently their plasma membrane triacylglycerol mass increased

Hypertriglyceridemia observed in animals after bacterial endotoxin administration and some forms of sepsis can result from increased hepatic triacylglycerol (TG) output or decreased TG clearance by extrahepatic tissues. To differentiate between these two possibilities, TG and free fatty acid (FFA)

OBJECTIVE Plasma very-low-density lipoprotein (VLDL) concentrations are increased during sepsis/endotoxaemia and VLDL may be substrates for the activated immune system. Lipid substrate utilisation by quiescent and activated macrophages was therefore examined. METHODS Rat R2 macrophages were

OBJECTIVE Limited knowledge exists regarding the lipid profiles of critically ill pediatric patients with systemic inflammatory response syndrome. The aim of this study was to evaluate the relationship between the intensity of the inflammatory response and changes in the lipid profiles of critically

Rainbow trout Oncorhynchus mykiss weighing 87 +/- 15 g (mean +/- SD) were infected with viral haemorrhagic septicaemia virus (VHSV) and the haematological and biochemical profiles of peripheral blood examined. Depending on the clinical signs and gross pathology, the fish were divided into 2 groups:

OBJECTIVE Changes in lipid profiles occur in systemic inflammatory response syndrome (SIRS), whether due to sepsis or another cause. Hypocholesterolemia associated with hypertriacylglycerolemia can lead to disease severity and higher mortality. The aim of this systematic review was to describe the

It has been claimed that lipid emulsions with a restricted linoleic acid content can improve the safety of total parenteral nutrition (TPN). The tolerability of TPN and its effects on the metabolism of fatty acids were assessed in this prospective, double-blind, randomised study comparing an

Most Staphylococcus aureus strains secrete two lipases SAL1 and SAL2 encoded by gehA and gehB. These two lipases differ with respect to their substrate specificity. Staphylococcus hyicus secretes another lipase, SHL, which is in contrast to S. aureus lipases Ca2+-dependent and has a broad-spectrum

Fat oxidation provides a fuel for many tissues and it provides an important signal to decrease glucose utilization and oxidation in muscle and so conserve glucose for essential organs such as the brain. The control of fatty acid oxidation is achieved in part through its plasma concentrations, which

BACKGROUND Nutrients may interfere with physiological and pathophysiologic mechanisms. The present study was aimed at evaluating whether the differences in the quality of energy substrates administered with total parenteral nutrition (TPN) after cytoreductive therapy may influence the clinical
