Upper gastrointestinal bleeding causes increased urea concentrations in patients with normal liver function and high ammonia concentrations in patients with impaired liver function. This ammoniagenesis may precipitate encephalopathy. The haemoglobin molecule is unique because it lacks the essential
A variable protein-induced toxicity has been reported in liver disease. The aim of this study was to establish the cause of increased ammonia liberation in the gut after intraluminal bleeding. Therefore, blood was sampled from catheterized piglets [20 +/- 0.8 kg (means +/- S.E.); n = 10] to
BACKGROUND
Previously, arterial concentrations of the essential branched chain amino acid isoleucine (Ile) were found to have decreased by more than 50% after gastrointestinal haemorrhage in patients and after intragastric blood administration in healthy humans and pigs. Hypothetically, this induced
BACKGROUND
A decrease in arterial isoleucine values after intragastric blood administration in pigs has been observed. This contrasted with increased values of most other amino acids, ammonia, and urea. After an isonitrogenous control meal in these pigs all amino acids including isoleucine
Upper gastrointestinal (GI) bleeding in cirrhotic patients has a high incidence of mortality and morbidity. Postbleeding catabolism has been hypothesized to be partly due to the low biological value of hemoglobin, which lacks the essential amino acid isoleucine. The aims were to study the metabolic
The phosphoprotein (P) of viral hemorrhagic septicemia virus (VHSV) plays an essential role in viral replication by interconnecting the L protein and the N protein-RNA complex. In this study, to investigate the role of the N-terminal region of the P protein in viral replication, we mutated the first
Despite advancements in medical and surgical therapies, clinical outcomes of aneurysmal subarachnoid hemorrhage (aSAH) continue to be poor. Currently, aSAH pathophysiology remains poorly understood. No aSAH biomarkers are commonly used in the clinical setting. This exploratory study Viral hemorrhagic septicemia virus (VHSV) is one of the most serious viral pathogen that infects farmed fish. In this study, we measured the replication of VHSV increased steadily at 9, 24, 72, and 120 h after infection and progression of necrosis was observed at 72 hpi. We performed transcriptomic
Objective The objective of this in silico study was to compare nucleotide and amino acids DENV-2-NS1 sequences isolated from febrile patients, with and without disease severity, from different South American countries. Matherials and Methods A bayesian MCMC phylogenetic analysis was carried out
High-energy collisional activation of doubly charged peptide ions allows direct sequential analysis of peptides over 4 kDa, including leucine/isoleucine determinations. This technique was used to verify the sequence of an intact beta-amyloid peptide associated with hereditary cerebral haemorrhage
(a) Hemorrhage in dogs (to 45-50 mm Hg) was associated with a 10-fold increase in plasma renin activity (PRA) which remained elevated throughout the time-course of shock including the irreversible (decompensation) stage. The presence of angiotensin II (AII) in arterial blood was demonstrated by the
The changes in hepatic energy charge, hepatic mitochondrial redox potential, and plasma amino acid concentrations were examined in rats following the induction of hemorrhagic shock with mean arterial blood pressure at 50 mmHg. Hepatic energy charge and mitochondrial redox potential decreased
Abnormal uterine bleeding (AUB), one of the most significant characters of incomplete abortion, is a widespread phenomenon in gynecological that put a woman into a terrible physiological and psychological state. Taohong Siwu Decoction (TSD) is a traditional Chinese medicine (TCM) prescriptions which
The authors describe the perivascular innervation of cerebral circulation. The different nerve fiber systems can be classified as follows: 1. Sympathetic (noradrenaline, neuropeptide Y), 2. Parasympathetic (acetylcholine, vasoactive intestinal peptide/peptide histidine isoleucine (methionine), 3.
Haemorrhages in the upper GI tract may lead to severe uraemia and, in patients with liver failure, to hyperammonaemia. The cause of this is not yet sufficiently clear. Recently we observed a decrease in arterial isoleucine levels after intragastric blood administration in pigs. This contrasted with
