Amyloid A (AA) amyloidosis, a fatal systemic amyloid disease, occurs secondary to chronic inflammatory conditions in humans. Although persistently elevated serum amyloid A (SAA) levels are required for its pathogenesis, not all individuals with chronic inflammation necessarily develop AA amyloidosis. Furthermore, many diseases in cats are associated with the elevated production of SAA, whereas ...

Aminoacyl-tRNAs (aa-tRNAs) are the essential substrates for translation. Most aa-tRNAs are formed by direct aminoacylation of tRNA catalyzed by aminoacyl-tRNA synthetases. However, a smaller number of aa-tRNAs (Asn-tRNA, Gln-tRNA, Cys-tRNA and Sec-tRNA) are made by synthesizing the amino acid on the tRNA by first attaching a non-cognate amino acid to the tRNA, which is then converted to the cog...

Examination of the entire von Willebrand factor (VWF) gene for mutations, particularly in types 1 and 3 von Willebrand disease (VWD) is becoming more widely practised. The sequence of the entire VWF gene will soon be compiled as a single sequence. For these reasons, a clearly defined nomenclature to use for numbering the VWF nucleotide and amino acid sequence is required. The following recommen...

Amino acids (AA) are important in poultry nutrition not only for protein deposition, but also for other metabolic functions; such as improving immune and gut functions. Although, some table values are available on amino acids requirement, AA requirements may vary due to changes in dietary composition and breeding selection. Thus amino acids requirements have remained an ongoing research topic. ...

Human defensins HNP-1 and -3 are broad spectrum antimicrobial peptides that are synthesized by human neutrophils as 94 amino acid (aa) precursors that require proteolytic removal of 64 amino-terminal residues to produce the mature defensins. Recent studies have shown that the early proteolytic processing events include two sequential cleavages, each removing 19 amino-terminal aa residues, that ...

The objectives of this study were to (1) identify changes in plasma and mammary intracellular amino acid (AA) profiles in dairy cows treated with growth hormone (GH), and (2) evaluate the expression of mammary gland genes involved in the transport of AA identified in (1). Eight non-pregnant (n = 4 per group) lactating dairy cows were treated with a single subcutaneous injection of either a slow...

We isolated and sequenced a plasmid, named pIP1714 (4,978 bp), which specifies resistance to streptogramins A and B and the mixture of these compounds. pIP1714 was isolated from a Staphylococcus cohnii subsp. cohnii strain found in the environment of a hospital where pristinamycin was extensively used. Resistance to both compounds and related antibiotics is encoded by two novel, probably cotran...

Sulfo and carboxyl group-containing polymers polymer/silica adsorbents poly(acrylonitrile-co-2-acrylamido-2-methylpropane-1-sulfonic acid-co-acrylic acid-co-N,N’-methylene-bis-acrylamide) [poly(AN-co-AMPS-co-AAco-MBA)] poly(AN-co-AMPS-co-AA-co-MBA)/SiO2 were synthesized by a UV-initiated polymerization or simultaneous in situ sol-gel process used as for removal of Co(II) Ni(II) ions from aqueou...

We have demonstrated that amino acids E (323), Y (324), E (330), and V (331) from the factor Va heavy chain are required for the interaction of the cofactor with factor Xa and optimum rates of prothrombin cleavage. We have also shown that amino acid region 332-336 contains residues that are important for cofactor function. Using overlapping peptides, we identified amino acids D (334) and Y (335...
