Rat Adrenal Chromaffin Cells Are Neonatal CO2 Sensors
(2005)
We studied the participation of adrenal medulla (AM) chromaffin cells in hypercapnic chemotransduction. Using amperometric recordings, we measured catecholamine (CAT) secretion from cells inAMslices of neonatal and adult ...

Preferred Sites of Exocytosis and Endocytosis Colocalize during High- But Not Lower-Frequency Stimulation in Mouse Motor Nerve Terminals
(SOC NEUROSCIENCE, 2009)
The spatial relationship of exocytosis and endocytosis in motor nerve terminals has been explored, with varied results, mostly in fixed preparations and without direct information on the utilization of each exocytic site. ...

Rotenone selectively occludes sensitivity to hypoxia in rat carotid body glomus cells
(Wiley-Blackwell Publishing Ltd., 2003)
Carotid body glomus cells release transmitters in response to hypoxia due to the increase of excitability resulting from inhibition of O2 -regulated K+ channels. However, the mechanisms involved in the detection of changes ...

Neuroprotective effect of adult hematopoietic stem cells in a mouse model of motoneuron degeneration
(2007)
Degenerative spinal motor diseases, like amyotrophic lateral sclerosis, are produced by progressive degeneration of motoneurons. Their clinical manifestations include a progressive muscular weakness and atrophy, which ...

CSP alpha-deficiency causes massive and rapid photoreceptor degeneration
(2006)
Cysteine string protein (CSP) _ is an abundant synaptic vesicle protein that contains a DNA-J domain characteristic of Hsp40-type cochaperones. Previous studies showed that deletion of CSP_ in mice leads to massive lethal ...

Regulation of oxygen sensing by ion channels
(2004)
O2 sensing is of critical importance for cell survival and adaptation of living organisms to changing environments or physiological conditions. O2-sensitive ion channels are major effectors of the cellular responses to ...

Diagnóstico manométrico y morfológico de la displasia neuronal colónica
(2003-07-01)
OBJETIVO Identificar los casos diagnosticados de Displasia Neuronal Intestinal (DNI) aislada tipo B. Comparar los casos identificados de DNI con un grupo control de niños estreñidos para diferenciar los hallazgos manométricos ...

Acoplamiento excitación-contracción en músculo liso: nuevo papel metabotrópico de los canales de calcio en la regulación del tono vascular
(2006-01-17)
El músculo liso es un tejido que se encuentra generalmente recubriendo órganos (músculo liso visceral: tubo digestivo, colon, próstata, etc.) y vasos sanguíneos (músculo liso vascular: venas y arterias), aunque también ...
