Tibetan natives have lived on the Tibetan plateau (altitude ∼4,000 m) for at
least 25,000 years, and as such they are adapted to life and reproduction in a
hypoxic environment. Recent studies have identified two genetic loci, EGLN1 and
EPAS1, that have undergone natural selection in Tibetans, and further
demonstrated an association of EGLN1/ EPAS1 genotype with hemoglobin
concentration. Both genes... hiện toàn bộ
Invited Review: Estrogens effects on the brain: multiple sites and molecular mechanismsJournal of Applied Physiology - Tập 91 Số 6 - Trang 2785-2801 - 2001
Bruce S. McEwen
Besides their well-established actions on reproductive functions, estrogens
exert a variety of actions on many regions of the nervous system that influence
higher cognitive function, pain mechanisms, fine motor skills, mood, and
susceptibility to seizures; they also appear to have neuroprotective actions in
relation to stroke damage and Alzheimer's disease. Estrogen actions are now
recognized to o... hiện toàn bộ
An analysis of aerobic capacity in a large United States populationJournal of Applied Physiology - Tập 60 Số 2 - Trang 494-500 - 1986
James A. Vogel, John F. Patton, Robert P. Mello, W. Lee Daniels
This study presents a description of aerobic capacity in a large US population
comprised of 1,514 men and 375 women. Such influencing factors as age, training
state, occupation, and body composition were evaluated. The population consisted
of new recruits entering the US Army from civilian life as well as soliders in a
variety of assignments and physical training programs. Age ranged from 17 to 55... hiện toàn bộ

Ozone-induced airway hyperresponsiveness and loss of neuronal M2 muscarinic receptor functionJournal of Applied Physiology - Tập 76 Số 3 - Trang 1088-1097 - 1994
A. H. Schultheis, David Bassett, A.D. Fryer
The effect of acute ozone exposure on the function of efferent parasympathetic
nerves, M3 muscarinic receptors on airway smooth muscle, and inhibitory M2
muscarinic receptors on the parasympathetic nerves was studied. Immediately
after exposure to 2.0 ppm ozone for 4 h, guinea pigs became hyperresponsive to
electrical stimulation of the vagus nerves. The normal airway response to
intravenous choli... hiện toàn bộ
