Proline metabolism was prospectively evaluated in patients with surgical sepsis, cirrhosis, and elective surgical procedures. Significant correlations were found in the septic patients. Proline levels were an excellent indicator of mortality and correlated positively with lactate levels. Lactate and
Recently, sepsis has been shown to impair intestinal amino acid absorption in addition to gut metabolic and barrier functions. We investigated intestinal proline absorption in a rabbit model of sepsis. Twelve hours after intraperitoneal injection of lipopolysaccharide, proline uptake by everted
The proline-specific enzymes dipeptidyl peptidase 4 (DPP4), prolylcarboxypeptidase (PRCP), fibroblast activation protein α (FAP) and prolyl oligopeptidase (PREP) are known for their involvement in the immune system and blood pressure regulation. Only very limited information is currently available
Pneumococcal surface protein A (PspA) and PspC of Streptococcus pneumoniae are surface virulence proteins that interfere with complement deposition and elicit protective immune responses. The C-terminal halves of PspA and PspC have some structural similarity and contain highly cross-reactive
The hypothesis has been advanced that the human systemic septic response is a function of the host and not of the type of infecting organism. Metabolic and physiologic data from five immunosuppressed transplant recipients with isolated cytomegaloviral sepsis and viremia were prospectively evaluated.
BACKGROUND
Intra-abdominal infection is generally considered a contraindication to primary colon anastomosis. In order to elucidate the mechanisms by which sepsis affects colonic healing, we studied anastomotic new collagen and protein synthesis and collagen gene expression in a relevant animal
The sequential changes in plasma free amino acid concentration were analyzed and compared in burned patients with sepsis (n = 12) and without sepsis (n = 19). After burn injury, phenylalanine, methionine, lysine, and the Phe/Tyr ratio were significantly increased in two groups (P < 0.05-0.01).
Systemic sepsis is associated with reduced mesenteric blood flow and impairment of metabolic and barrier functions of the small intestine. A study was performed in the rat to investigate the effect of sepsis induced by caecal ligation and double puncture on intestinal absorption of leucine and
BACKGROUND
Sepsis has been shown to impair the barrier function and metabolism of the intestine. This study was done to investigate the effect of sepsis on intestinal absorption of proline, leucine, glutamic acid, and aminoisobutyric acid.
METHODS
Rats (six per group) were studied 24 hours after
The concentrations of acetoacetate, beta-hydroxybutyrate, and adenine nucleotides, and the mitochondrial phosphorylative activities, induced by cecal ligation and punctured in the liver of septic rats, were determined. The concentrations of glucose, free fatty acids (FFA), and free amino acids in
Diketopiperazine is produced by various organisms, including bacteria, fungi, and animals, and has been suggested as a novel signal molecule involved in the modulation of genes with various biological functions. Vibrio vulnificus, which causes septicemia in humans, produces
The body clearance of 10 plasma amino acids (AA) was determined from the rate of compared muscle-released AA and AA administered by infusion of total parenteral nutrition (TPN) compared to their estimated extracellular (ECW) pool in patients with multiple trauma with (n = 10) or without (n = 16)
Although intra-abdominal sepsis is known to impair colon healing by inhibiting anastomotic collagen synthesis, the effect of systemic sepsis on this process is unknown. Endotoxins and cytokines associated with sepsis induce nitric oxide synthesis both systemically and locally within colonic tissue.
Sepsis-induced muscle atrophy is produced in part by decreased protein synthesis mediated by inhibition of mTOR (mammalian target of rapamycin). The present study tests the hypothesis that alteration of specific protein-protein interactions within the mTORC1 (mTOR complex 1) contributes to the
The development of the multiorgan dysfunction syndrome, directly determining the severity of the septic process, is characterized by not only inverse ratio of the energy and plastic material, but by metabolic changes which are still unclear and cannot yet be explained. Our purpose was to detect some
