A substrate-specific calmodulin-dependent myosin light-chain kinase (MLCK) was purified 45,000-fold to near homogeneity from bovine brain in 12% yield. Bovine brain MLCK phosphorylates a serine residue in the isolated turkey gizzard myosin light chain (MLC), with a specific activity of 1.8 mumol/min per mg of enzyme. The regulatory MLC present in intact gizzard myosin is also phosphorylated by ...

Most studies that have examined mercury (Hg) contamination of fish have focused on game species feeding near the top of the food web, while studies that examine forage fish that feed near the base of the food web are rare. We conducted a survey of Hg contamination in three species of forage fish, brook silverside (Labidesthes sicculus), threadfin shad (Dorosoma petenense) and gizzard shad (Doro...

This work focused on the investigation and evaluation of the single or individual effects of feed-inoculum ratio, temperature, and agitation speed (i.e. operating variables) on biomethanization of the mixture of cattle manure, pig manure and poultry manure (mixed animal wastes) co-digested with pineapple fruit waste and content of chicken-gizzard (inoculum) as well as to model the kinetics of b...

This study reports the complete genome sequence of fowl aviadenovirus A strain JM1/1, which caused gizzard erosions in broilers occurring in Japan. The JM1/1 genome is 43,809 bp in length and most closely related to the strain chicken embryo lethal orphan (CELO); moreover, multiple site insertions and deletions were found.

a histological and histochemical study of the stomach (proventriculus and gizzard) of the passer domesticus was carried out, under light microscopy.in the present study, we prepared 12 adult passer domesticus (both sex) captured in the country side of mashhad, iran. after euthanasia with ether inhalation, the digestive tract was exposed and fragments of the stomach (proventriculus and gizzard) ...

Cross-linking of actin filaments (F-actin) into bundles and networks was investigated with three different isoforms of the dumbbell-shaped alpha-actinin homodimer under identical reaction conditions. These were isolated from chicken gizzard smooth muscle, Acanthamoeba, and Dictyostelium, respectively. Examination in the electron microscope revealed that each isoform was able to cross-link F-act...

background and objectives: the aim of our study was to characterize gizzard lactobacillus fermentum-group strains on the basis of their phenotypic profiles regarding characteristics of lactobacilli. in addition, their in vitro potential probiotic properties were evaluated. materials and methods: the lactic acid bacteria were isolated and identified from gizzard contents of algerian local poultr...

three adult pigeons (columbia livia) belonging to a pigeon farm in mashhad area were submitted topoultry clinic of school of veterinary medicine for post-mortem inspection. the farm had 150 adult pigeonsand a number of them suffered from a chronic disease with body weight loss, diarrhoea and weakness. atnecropsy, slight to extreme enlargement with distortion were observed in gizzards of all car...
