How can you use “beta-adrenergic” in a sentence? Here are some example sentences to help you improve your vocabulary:
Similarly, Tse [ 48 ] found that in compensated hypertrophy the population of beta-adrenergic receptors is relatively normal, but in heart failure, the beta receptors have both down-regulated and de-sensitized.
However, our finding that a daily injection of the beta-blocker propanolol does not prevent the development of iron deficient cardiac hypertrophy suggests that beta-adrenergic sympathetic stimulation may not be a causal agent in the development of hypertrophy.
Finally, propanolol injections do not prevent the development of iron deficient cardiac hypertrophy, drawing into question the potential causal relationship between beta-adrenergic neurotransmission and this form of hypertrophy.
Many studies have shown that chronic intravenous infusion of norepinephrine is sufficient to cause hypertrophy, and that various forms of hypertrophy are linked to a decrease in either beta-adrenergic receptor density or a decreased responsiveness to beta-adrenergic stimulation [ 46 48 49 56 57 58 59 60 61 62 63 ] . Barth, for example, showed that norepinephrine infusion induced left ventricular hypertrophy that could be prevented by an adrenergic-receptor blocker [ 58 ] . It has been suggested that ornithine decarboxylase is a link between beta-adrenoreceptors and stimulation of tissue growth factor, which results in hypertrophy [ 64 ] . However, recent studies have focused on alpha-adrenergic reception as a mediator of cardiac hypertrophy [ 35 ] , although some question the role of the alpha-adrenergic receptor as a hypertrophic mediator in vivo [ 34 ] . To date, no published studies of which we are aware have examined alpha-adrenergic reception and the development of cardiac hypertrophy with iron deficiency.
Most have demonstrated alterations in either plasma or heart norepinephrine content, and a de-sensitization of the beta-adrenergic receptors of the heart [ 24 25 26 27 28 29 30 31 32 33 ] . Recently, the alpha-adrenergic receptor has been shown in vitro to be an important modulator of ventricular hypertrophy.
