Histochemical Demonstration of Uptake of Exogenous Norepinephrine by Adrenergic Fibers in vitro

Adrenergic fibers in isolated iris preparations were demonstrated histochemically by means of the formaldehyde condensation technique. In the presence of adenosine triphosphate (ATP) there was a net u... read more

Neuroendocrinology of the Skin

Demonstration of the corresponding receptors in the same cells suggests para- or autocrine mechanisms of action. These findings, together with the demonstration of cutaneous production of numerous oth... read more

Responsiveness of Human Infant Cerebral Arteries to Sympathetic Nerve Stimulation and Vasoactive Agents

To visualize the adrenergic innervation of some vessels ... to mask the nonspecific background fluorescence associated with elastin fibers (21). Segments were placed flat on a glass slide with the adv... read more

Localizing Tritiated Norepinephrine in Sympathetic Axons by Electron Microscopic Autoradiography

Concentrations of photographic grains were observed only over regions of preterminal autonomic axons containing granulated vesicles, thereby directly demonstrating uptake of norepinephrine into these ... read more

κ-Opioid Receptor Antagonism Improves Recovery from Myocardial Stunning in Chronically Instrumented Dogs

The suggested local myocardial release of norepinephrine from autonomic nerve endings after κ-opioid receptor antagonism may explain this discrepancy. Acting on coronary adrenergic receptors ... myoca... read more

Neurobiological Mechanisms of the Onset of Puberty in Primates

Norepinephrine transporter (NET) is also likely involved in the NE turnover rate. Although the role of NET in control of LHRH release has been studied in adult monkeys (459, 460), its role in puberty ... read more

Intra- and extra-cellular lactate shuttles

However, during exercise when arterial [lactate] rises, exogenous (arterial ... lactate production at sites of high glycolytic flux (e.g., Type IIB muscle fibers), lactate uptake and removal at highly ... read more
