Paraganglioma of the spermatic cord. Report of a case with immunohistochemical and ultrastructural studies
(1990-01-01)
We describe a case of paraganglioma arising in the spermatic cord, which is an extremely rare location. Immunohistochemical studies characterized two types of cells: (1) polygonal cells expressing neuron-specific enolase, ...
INTERMITTENT ACTIVATION OF PERIPHERAL CHEMORECEPTORS IN AWAKE RATS INDUCES Fos EXPRESSION IN ROSTRAL VENTROLATERAL MEDULLA-PROJECTING NEURONS IN THE PARAVENTRICULAR NUCLEUS OF THE HYPOTHALAMUS
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Despite the well-established sympathoexcitation evoked by chemoreflex activation, the specific sub-regions of the CNS underlying such sympathetic responses remain to be fully characterized. In the present study we examined ...
Enhanced Expression of Heme Oxygenase-1 and Carbon Monoxide Excitatory Effects in Oxytocin and Vasopressin Neurones During Water Deprivation
(WILEY-BLACKWELLMALDEN, 2012)
A growing body of evidence indiates that carbon monoxide (CO) acts as a gas neurotransmitter within the central nervous system. Although CO has been shown to affect neurohypophyseal hormone release in response to osmotic ...
How the stimulus defines the dynamics of vesicle pool recruitment, fusion mode, and vesicle recycling in neuroendocrine cells
(Wiley Blackwell Publishing, Inc, 2016-06)
The pattern of stimulation defines important characteristics of the secretory process inneurons and neuroendocrine cells, including the pool of secretory vesicles beingrecruited, the type and amount of transmitters released, ...
PURIFICATION AND CHARACTERIZATION OF A DYNORPHIN-PROCESSING ENDOPEPTIDASE
(Amer Soc Biochemistry Molecular Biology Inc, 1995-10-06)
Dynorphin B (Dyn B-13, also known as rimorphin) is generated from Dyn B-29 (leumorphin) by the cleavage at a single Arg residue. An enzymatic activity capable of processing at this monobasic site has been previously reported ...
Insulin-like peptide genes in honey bee fat body respond differently to manipulation of social behavioral physiology
(COMPANY OF BIOLOGISTS LTD, 2011)
Nutrient sensitive insulin-like peptides (ILPs) have profound effects on invertebrate metabolism, nutrient storage, fertility and aging. Many insects transcribe ILPs in specialized neurosecretory cells at changing levels ...
Nitric oxide modulates the firing rate of the rat supraoptic magnocellular neurons
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
In vitro, nitric oxide (NO) inhibits the firing rate of magnocellular neurosecretory cells (MNCs) of hypothalamic supraoptic and paraventricular nuclei and this effect has been attributed to GABAergic activation. However, ...
Cyclic Guanosine Monophosphate Signaling Cascade Mediates Pigment Aggregation in Freshwater Shrimp Chromatophores
(MARINE BIOLOGICAL LABORATORY, 2009)
The cell signaling cascades that mediate pigment movements in crustacean chromatophores are not yet well established, although Ca(2+) and cyclic nucleotide second messengers are involved. Here, we examine the participation ...
