Clinical and morphological characteristics of head-facial haemangiomas

Head & Face Medicine, 2007
Background Haemangiomas of the head or face are a frequent vascular pathology, consisting in an embryonic dysplasia that involves the cranial-facial vascular network.

The (--)[3H]dihydroalprenolol binding to rat adipocyte membranes: an explanation of curvilinear Scatchard plots and implications for quantitation of beta-adrenergic sites

Journal of Lipid Research, 1982
In rat adipocyte membranes, both beta-adrenergic agonists and beta-adrenergic antagonists competed with (--)[3H]dihydroalprenolol for high affinity (KD 2-4 nM) and low capacity binding sites.

BETA-ADRENERGIC RECEPTORS IN VARIOUS ORGANS

Japanese Journal of Pharmacology, 1970
The concept of two adrenergic receptor mechanisms or α- and β-adrenergic receptor systems, originally postulated by Ahlguist (1) is presently accepted. Furchgott (2) has presented evidence suggesting that there may be different types of receptors in the β- class.

Adrenergic regulation of adipocyte metabolism.

Journal of Lipid Research, 1983
Adipocytes can be readily isolated from intact adipose tissue. In adipocytes from hamster and human white adipose tissue it is possible to demonstrate beta, alpha 1, and alpha 2 adrenoceptors.

Influence of development and reduction of fat stores on the antilipolytic alpha 2-adrenoceptor in hamster adipocytes: comparison with adenosine and beta-adrenergic lipolytic responses

Journal of Lipid Research, 1983
The response of the hamster adipocyte to various lipolytic (beta-adrenergic) and antilipolytic (alpha(2)-adrenergic and adenosine-dependent) stimuli was studied during the development and after cold-induced regression of fat stores.

Efficacy of beta 1-adrenergic receptors is lower than that of beta 2-adrenergic receptors. [PDF]

Proceedings of the National Academy of Sciences, 1993
We investigated the relative activity at which fully occupied human beta 1- and beta 2-adrenergic receptors (beta 1AR and beta 2AR) activate the stimulatory G protein (Gs)/adenylyl cyclase (AC) system in isolated membranes. The receptors were cloned and coexpressed in permanent cell lines at beta 1/beta 2 ratios that varied from 1:2 to 3:1 and at total

Beta-adrenergic blocking agents in cutaneous and oral melanoma

Oral Oncology Reports
Beta-adrenergic blocking agents, or beta-blockers, are primarily used to manage cardiovascular conditions such as hypertension, heart failure, and arrhythmias by blocking the effects of stress hormones on beta-adrenergic receptors, reducing heart rate ...

A reliable assay for beta-adrenoceptors in intact isolated human fat cells with a hydrophilic radioligand, [3H]CGP-12177.

Journal of Lipid Research, 1988
The beta-adrenergic receptors of isolated human fat cells were identified using a new hydrophilic beta-adrenergic radioligand (+/-)[3H]CGP-12177. The results were compared with those from [3H]dihydroalprenolol binding to fat cells and membranes.

Impact of noradrenergic inhibition on neuroinflammation and pathophysiology in mouse models of Alzheimer’s disease

Journal of Neuroinflammation
Norepinephrine (NE) modulates cognitive function, arousal, attention, and responses to novelty and stress, and it also regulates neuroinflammation. We previously demonstrated behavioral and immunomodulatory effects of beta-adrenergic pharmacology in ...

Beta-Blockers and Cancer: Where Are We?

Pharmaceuticals, 2020
Cancer is one of the leading causes of death worldwide. After diagnosis, cancer treatment may involve radiotherapy, chemotherapy, and surgery. Several of the approaches used to treat cancer also attack normal cells and, thus, there is the need for more ...
