Altered diaphragm contractile properties with controlled mechanical ventilation.
This study shows that, over time, diaphragm inactivity with controlled mechanical ventilation (CMV) decreases diaphragm force and produces myofibril damage contributing to the reduced force. WeExpand

Effects of voluntary activity and genetic selection on aerobic capacity in house mice (Mus domesticus).
An animal model was developed to study effects on components of exercise physiology of both "nature" (10 generations of genetic selection for high voluntary activity on running wheels) and "nurture"Expand

Role of ryanodine receptor channels in Ca2+ oscillations of porcine tracheal smooth muscle.
Acetylcholine (ACh) induces repetitive, propagating intracellular Ca2+ concentration ([Ca2+]i) oscillations in porcine tracheal smooth muscle (TSM) cells. Using real-time confocal microscopy, weExpand

Diaphragm dysfunction in chronic obstructive pulmonary disease.
RATIONALE Hypercapnic respiratory failure because of inspiratory muscle weakness is the most important cause of death in chronic obstructive pulmonary disease (COPD). However, the pathophysiology ofExpand

Lymphocyte Function-Associated Antigen 1 Is a Receptor for Pasteurella haemolytica Leukotoxin in Bovine Leukocytes
ABSTRACT Pasteurella (Mannheimia) haemolytica leukotoxin (Lkt) causes cell type- and species-specific effects in ruminant leukocytes. Recent studies indicate that P. haemolytica Lkt binds to bovineExpand

Pressure-time product during continuous positive airway pressure, pressure support ventilation, and T-piece during weaning from mechanical ventilation.
The objective of this study was to compare the effects of continuous positive airway pressure (CPAP), pressure support ventilation (PS), and T-piece on the pressure-time product (PTP) during weaningExpand

Maximum specific force depends on myosin heavy chain content in rat diaphragm muscle fibers.
In the present study, myosin heavy chain (MHC) content per half sarcomere, an estimate of the number of cross bridges available for force generation, was determined in rat diaphragm muscle (Dia(m))Expand

Oxidative capacity of human muscle fiber types: Effects of age and training status
Morphometry and oxidative capacity of slow-twitch (type I) and fast-twitch (type IIa and IIb) muscle fibers obtained from vastus lateralis needle biopsies were compared between younger (21-30 yr) a...
