(1) alpha 1-Adrenergic agonists, phenylephrine and norfenefrine, did not affect the synthesis.
(2) Data obtained with fenoldopam were corroborated with use of SK&F 38393, another dopamine D1-receptor agonist.
(3) The GABA receptor agonist progabide reduced VCMs and locomotor activity.
(4) This novel mechanism of receptor regulation, named transmodulation, should be distinguished from the reduction in total receptor number caused by the homologous ligand (downregulation) and from the change in affinity produced by the binding of agonists or antagonists to the same receptor site.
(5) Exposure to nanomolar concentrations of saralasin, an Ang II agonist, attenuated the passage of the fluorophores across the monolayers by 50-75%.
(6) The effects of low doses of dihydropyridine (DHP) calcium channel antagonists nimodipine, nifedipine, (-)-R-202-791, and amlodipine, the DHP calcium channel agonist BAY K 8644 were investigated on clonic convulsions to pentylenetetrazole (PTZ) in mice.
(7) The binding to DNA-cellulose of heat-activated [3H]RU486-receptor complexes was slightly decreased (37%) when compared with that of the agonist [3H]R5020-receptor complexes (47%).
(8) These later results suggest that dopamine agonists increase sensorimotor reactivity measured with acoustic startle by acting on sensory rather than motor parts of the reflex arc.
(9) Only methoxyindole acetic acid was detectable after incubation of unstimulated and alpha-adrenergic-agonist-treated pineal glands.
(10) It inhibits platelet and vascular smooth muscle activation by cGMP-dependent attenuation of the agonist-induced rise of intracellular free Ca2+.
(11) The elimination half-life of most beta-agonists is relatively short, and pharmacokinetics are independent of dose and duration of treatment.
(12) Substance P (SP), a relatively non-selective tachykinin receptor agonist, and Septide and Senktide, highly selective NK-1 and NK-3 tachykinin receptor agonists, respectively, were injected intradermally in rats.
(13) Responses of control tissues to an alpha agonist (norepinephrine) were increased at lower temperatures and responses to a beta agonist (isoprenaline) were increased at higher temperatures.
(14) The inhibition of all three agonist responses by 1.1 mM calcium was competitive.
(15) The alpha 2 agonist, clonidine, produced a larger dose-related increase in food intake in lean rats than in the fatty rats.
(16) This stimulation is mediated by one receptor with an apparent affinity of 3.3 X 10(-6) M. The hydroxyl group in the para position on phenylethanolamine was absolutely necessary to obtain an agonist whereas the meta hydroxyl group or the presence of a catechol almost suppressed the activity.
(17) The alpha 2-adrenoceptor agonist clonidine is most potent for stimulating Isc.
(18) Moreover, the ribosylation inhibitors converted the glucocorticoid antagonist RU-486 into a potent agonist for cytolysis of L1210 cells.
(19) We have characterized the effects of adenosine, the A1-receptor agonist N6-(L-2-phenylisopropyl)-adenosine (PIA) and the A2-receptor agonist 5'-(N-ethyl)-carboxamido-adenosine (NECA), in isolated human pulmonary vessels.
(20) Long-term treatment with agents that stimulate the beta-receptor (prenalterol and pirbuterol) has not proved to be useful in the treatment of chronic heart failure; moreover, prolonged treatment with beta-agonists (dobutamine and pirbuterol) may adversely affect survival.
Athletic
Definition:
(a.) Of or pertaining to athletes or to the exercises practiced by them; as, athletic games or sports.
(1) Compared with conservative management, better long-term success (determined by return of athletic soundness and less evidence of degenerative joint disease) was achieved with surgical curettage of elbow subchondral cystic lesions.
(2) In a comparative study 11 athletes and 11 untrained students were investigated at rest, of these 6 trained and 5 untrained individuals during exercise as well.
(3) During recovery, while the heart rate decreased and the RR interval variance increased, there was a relative increase in LF and a relative decrease in HF in normal subjects (either sedentary or athletic).
(4) When allegations of systemic doping and cover-ups first emerged in the runup to the 2013 Russian world athletics championships, an IOC spokesman insisted: “Anti-doping measures in Russia have improved significantly over the last five years with an effective, efficient and new laboratory and equipment in Moscow.” London Olympics were sabotaged by Russia’s doping, report says Read more We now know that the head of that lauded Moscow lab, Grigory Rodchenko, admitted to intentionally destroying 1,417 samples in December last year shortly before Wada officials visited.
(5) "He's defined by being himself, by being smart, by being a good athlete," Goldwater said of Keller.
(6) "They haven't just got to be able to run like athletes," says Hall.
(7) #Tigers #Athletics @HunterFelt October 11, 2013 David Lengel (@LengelDavid) @HunterFelt Unless you're Yoenis Cespedes of course!
(8) The brightly lit ice palaces themselves are stunning, inside and out, and the sporting facilities have been rightly praised by almost all the athletes.
(9) However, the mean serum EPO concentrations of male and female athletes engaged in a variety of sports were not different from those of sedentary control subjects of both sexes (26.5-35.3 U.ml-1).
(10) Sudden death in healthy athletes is uncommon but, when it occurs, the primary mechanism is cardiovascular.
(11) Thus many athletes sustain dental-related injuries resulting in deformity and discomfort which may persist throughout their lives.
(12) He is big, strong, athletic, very quick and has got a fantastic leap on him," said McClaren.
(13) The increased volume of flowing blood and increased stroke volume in athletes probably allows for a reduction in flow velocity and thereby a reduction in kinetic energy.
(14) In Iten, I heard stories of athletes being told weeks in advance when to attend the testing centre in Eldoret.
(15) Many athletes, particularly female, are iron depleted, but true iron deficiencies are rare.
(16) Maximal power output was on average 81.1 W for the male population and varied from 65.8 W for class II athletes to 92.2 W for class LA.
(17) These results indicate that the increase in glucose storage by acute exercise is not systematically associated with an improved glucose homeostasis, suggesting that other adaptive mechanisms also contribute to the improvement of insulin sensitivity in endurance athletes.
(18) An echocardiographic evaluation of 77 members of a championship childhood swim team showed dimensional variations from normal in most athletes.
(19) Ballet dancers generated significantly less mechanical power than indoor soccer, basketball and bobsled athletes, while wrestlers generated significantly less power than indoor soccer and basketball athletes (all p less than 0.05).
(20) (GL) and M. deltoideus (D) were studied in 89 athletes practising 11 different sport events.
