Residues Arg283, Arg285, and Ile287 are highly conserved amino acids in bovine viral diarrhea virus RNA polymerase (BVDV RdRp) and RdRps from related positive-strand RNA viruses. This motif is an important part of the binding pocket for the nascent RNA base pair during initiation and elongation. We
Bovine viral diarrhea virus (BVDV) is associated with a range of economically important diseases of cattle including reproductive disorders and an acute fatal hemorrhagic disease. Neutralizing antibodies that bind to the E2 glycoprotein are important predictors of vaccinal immunity. Neutralization
An inherited defect in intestinal anion exchange, congenital chloride diarrhea (CLD), was recently shown to be caused by mutations in the down-regulated in adenoma (DRA) gene. A three base pair deletion resulting in the loss of an amino acid valine (V317del) in the predicted CLD/DRA protein was
The effects of cytopathic (cp) and non-cytopathic (ncp) bovine viral diarrhea virus (BVDV) on the cellular metabolic activity and activation status of bovine peripheral blood mononuclear cells (PBMC) were investigated. Cellular DNA and protein synthesis was determined by [3H]thymidine and [3H]valine
Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder, which is commonly treated with antidiarrhoeal, antispasmodics, serotonergic agents or laxative agents. These treatments provide relief for IBS symptoms but may also lead to undesired side effects. The effects of Ile and Val supplementation of a low-CP, corn-wheat-soybean meal-based piglet diet on growth performance, incidence of diarrhea, and N balance were studied using 60 Landrace x Duroc male piglets in a 4-wk experiment. The 60 individually caged piglets were divided into 5 dietary
Tumors associated with the Verner Morrison syndrome secrete peptide histidine methionine, its C-terminally extended variant peptide histidine valine, and vasoactive intestinal peptide. There is evidence that vasoactive intestinal peptide mediates diarrhea, but recent evidence suggested that peptide
Intravenous infusion of low doses of vasoactive intestinal polypeptide, peptide histidine valine-42, and peptide histidine methionine (and the rat equivalent, peptide histidine isoleucine) into anesthetized rats caused a reduction in net absorption of fluid from the small intestine. Larger doses
Familial amyloidotic polyneuropathy (FAP) is an autosomal dominant disorder caused by mutation in the transthyretin gene. The most common mutation is substitution of valine for methionine at position 30 (MET30). Liver transplantation (LT) is the preferred treatment. After LT, although many patients
Bovine rotavirus strain B223 is the North American prototype for group A P8[11] serotype/genotype rotaviruses. Rotaviruses with this serotype/genotype are a prevalent cause of neonatal calf diarrhea and have also been isolated from asymptomatic human infants. On the basis of deduced amino acid
BACKGROUND
Bu-zhong-yi-qi-tang (BT) is a classical formula for the treatment of spleen-qi descending, visceroptosis with hyposplenic qi, uterine prolapse, and rectal prolapse due to chronic diarrhea in traditional Chinese medicine (TCM) and has been identified as an effective drug for the treatment
Five infants from 3 families, one Egyptian, two Yemeni, are described with a progressive encephalopathy, four of whom have been studied in detail. All patients showed vascular lesions of the skin, characterized by waxing and waning petechiae and ecchymoses. Acrocyanosis was present in three
Maple syrup urine disease (MSUD) is an autosomal recessive aminoacidopathy secondary to an enzyme defect in the catabolic pathway of the branched-chain amino acids (BCAAs: leucine, isoleucine, and valine). Accumulation of their corresponding keto-acids leads to encephalopathy if not treated in time.
BACKGROUND
Clinical pictures resembling acrodermatitis enteropathica have been described in acquired zinc deficiency and deficiencies of other nutrients such as biotin, essential fatty acids and amino acids as well as biotin metabolism disorders. We describe the case of an infant with maple syrup
The fimbral colonization factor antigen CFA/I of enterotoxigenic Escherichia coli was purified and characterized. The initial purification step was release of these fimbriae from the bacterial cells by homogenization with a Waring blender. Common fimbriae and flagellar antigen were avoided by
