Zymogen granules of mouse parotid acinar cells are acidified in situ in an ATP-dependent manner
(Springer-Verlag, 1988-07)
The mechanism for acidification of zymogen granules in acinar cells of mouse parotid gland was explored using acridine orange, lysosomotropic agents, and an inhibitor of cellular ATP production. Methylamine and monensin ...
Mastoparan induces oscillations of cytosolic Ca2+ in rat pancreatic acinar cells
(Elsevier, 1991-05-31)
Microfluorimetry of fura-2 was used to monitor [Ca2+]i in single cells stimulated with the G-protein activating agent mastoparan. Mastoparan induced the generation of [Ca2+]i oscillations, which in contrast to oscillations ...
Neuroendocrine regulation of seasonal breeding cycles in the ewe
(Wiley Subscription Services, Inc., A Wiley Company, 1990)
Seasonal reproduction has emerged as an important topic of investigation which bridges the areas of endocrinology, neurobiology, biological rhythms, and fertility regulation. Among the species in which this topic has been ...
Seasonal acclimatization to temperature in cardueline finches
(Springer-Verlag, 1978-06)
1. Seasonal variation in body constituents and utilization of lipid, protein, and carbohydrate during cold stress in American goldfinches were studied to determine relations of these functions to the pronounced seasonal ...
Skeletal muscle fiber regeneration following heterotopic autotransplantation in cats
(Elsevier, 1976-07-15)
Whole 3 g extensor digitorum longus (EDL) muscles of cats were autotransplanted. The EDL muscles were either transplanted without denervation prior to transplantation (normal transplants) or denervated 3 to 4 weeks prior ...
Autoradiographic evidence that transport of newly synthesized neuropeptides is directed to release sites in the X-organsinus gland of Cardisoma carnifex
(Springer-Verlag, 1991-05)
Sections of isolated X-organ — sinus gland neurosecretory systems of the crab, Cardisoma carnifex , were studied by light-and electron microscopy with conventional and autoradiographic procedures. The somata only were ...
Stimulation of myenteric plexus neurite outgrowth by insulin and insulin-like growth factors I and II
(Elsevier, 1992)
A defined culture medium containing insulin, insulin-like growth factor I (IGF-I) or insulin-like growth II (IGF-II) supported morphological development of myenteric plexus neurons derived from neonatal guinea pigs. Insulin ...
Spatial compartmentalization of signal transduction in insulin action
(John Wiley & Sons, Inc., 2001-03)
Insulin resistance is thought to be the primary defect in the pathophysiology of type 2 diabetes. Thus, understanding the cellular mechanisms of insulin action may contribute significantly to developing new treatments for ...
Prostaglandin biosynthesis does not participate in isoproterenol-induced renin release
(Elsevier, 1984-05-07)
Rat renal slices were incubated in two different media. One was a normal K. physiological saline solution and the other a high K medium. Renin release was measured every 15 min in the presence and absence of 10-6M isoproterenol ...
