The objective of this study was to determine the relationship between developmental transitions in myosin heavy chain (MHC) composition and changes in maximum unloaded shortening velocity (Vo) and maximum specific force (Po) of the rat diaphragm muscle. The diaphragm was excised at postnatal days 0, 3, 7, 14, 21, and 28 and in adults. MHC isoform expression(More)
BACKGROUND In the northern hemisphere winter of 2003-04 antigenic variant strains (A/Fujian/411/02 -like) of influenza A H3N2 emerged. Circulation of these strains in the UK was accompanied by an unusually high number of laboratory confirmed influenza associated fatalities in children. This study was carried out to better understand risk factors associated(More)
The impact of hypothyroidism (Hyp) on myosin heavy chain (MHC) isoform expression, maximum specific force (P0), fatigability, and maximum unloaded shortening velocity (V0) was determined in the rat diaphragm muscle (Dia) at 0, 7, 14, 21, and 28 days of age. Hyp was induced by treating pregnant rats with 6-n-propyl-2-thiouracil (0.05% in drinking water)(More)
ABSTRACT: The effect of postnatal age on norepinephrinc-induccd α2-adrenoreceptor-mediated release of endothelium-derived relaxing factor in porcine intramuscular pulmonary arteries was studied. Rings of pulmonary artery from fetal, newborn, 3-d-, 10-d-, 9-wk-, and 15-wk-old pigs with and without cndothelium were suspended for isometric force measurement in(More)
A recombinant AcMNPV containing the green fluorescent protein (gfp) gene under the polyhedrin promoter (polh) was used to investigate the expression of the gfp gene as well as the production of recombinant extracellular virus in 14 continuous insect cell lines, including Heliothis virescens (BCIRL-HV-AM1), Helicoverpa zea (BCIRL-HZ-AM1), Anticarsia(More)
A mutant LLC-PK1 cell line, M18, was isolated after a single treatment of the parent culture with N-methyl-N'-nitro-N-nitroso-guanidine. In contrast to LLC-PK1 cells, the mutant did not exhibit production of urokinase-type plasminogen activator (uPA) in response to the hormones calcitonin and vasopressin, but produced the expected levels of uPA upon(More)
Ketamine is a potent bronchodilator, but its mode of action is unclear. We have studied the effect of ketamine on the peripheral vagus nerve motor pathway of isolated porcine trachealis muscle. Postsynaptic nicotinic cholinergic receptors of the intramural ganglia were stimulated selectively with 1,1-dimethyl-4-phenyl-piperazinium iodide, post-ganglionic(More)
