The primary purpose of this study was to determine whether various agents (adenosine 3-thiotriphosphate [ATP gamma S], trifluoperazine [TFP], troponin I, the catalytic subunit of the cyclic adenosine 3',5'-monophosphate dependent protein kinase [C-subunit], and calmodulin [CaM]) could be used to classify skinned fiber types, and then to determine whether the proposed mechanisms for Ca2+ regulat...
A simple and rapid procedure for the purification of the native form of chicken gizzard myosin light-chain kinase (Mr 136000) is described which eliminates problems of proteolysis previously encountered. During this procedure, a calmodulin-binding protein of Mr 141000, which previously co-purified with the myosin light-chain kinase, is removed and shown to be a distinct protein on the basis of ...
The taxonomy of Anhangatermes Constantino 1990 is revised. Four new species are described: Anhangatermes anhanguera, sp. n., Anhangatermes eurycephalus, sp. n., Anhangatermes juruena, sp. n., and Anhangatermes pilosus, sp. n. The imago of Anhangatermes is described for the first time (A. pilosus). A key to the species of the genus based on soldiers and workers is provided. The diagnosis of the ...
Nexuses are described between the smooth muscle cells of the gizzard of the chick and the pigeon, the vas deferens of the mouse and the guinea pig, and the taenia coli of the guinea pig. The nexuses in the gizzard were examined after osmium tetroxide and potassium permanganate had been used as fixatives. Although differences in the dimensions of the unit membranes and the nexuses were noted, th...
Enzootic outbreak of necrotic gastritis associated with Clostridium perfringens in broiler chickens.
Clinical morphological investigations were carried out in a flock of 22,000 Ross 308 broiler chickens at the age of 38 days that experienced a sudden increase in mortality rates. Morbidity and mortality rates were followed and gross anatomical examination of 150 bodies (7%) of all 1541 dead chickens was performed. In all necropsied birds, without exception, the typical macroscopic lesions were ...
Three experiments were conducted to evaluate the effects of corn particle size on growth performance, ME(n), apparent total tract amino acid digestibility, and cecal microbial populations when young chicks were fed a corn-soybean meal-based diet. In all experiments, 1-d-old chicks were randomly assigned to 1 of 4 dietary treatments containing corn particle geometric mean diameters of 557, 858, ...
