To determine whether intramural nerves affect intestinal ion transport, we studied the effect of electrical field stimulation (EFS) on the movement of ions across isolated rabbit ileum. EFS increased the transmural electrical potential difference and the short circuit current (Isc), caused C1 secretion, and reduced conductance, but did not alter fluxes of Na or the residual current (JRnet). The...

The iron-sulfur cluster (ISC) is an ancient and essential cofactor of many proteins involved in electron transfer and metabolic reactions. In Arabidopsis, three pathways exist for the maturation of iron-sulfur proteins in the cytosol, plastids, and mitochondria. We functionally characterized the role of mitochondrial glutaredoxin S15 (GRXS15) in biogenesis of ISC containing aconitase through a ...

Am J Physiol Cell Physiol 279: C461–C479, 2000.—Forskolin, UTP, 1-ethyl-2-benzimidazolinone (1EBIO), NS004, 8-methoxypsoralen (Methoxsalen; 8-MOP), and genistein were evaluated for their effects on ion transport across pri...

This study focuses on image sensor communication (ISC), which is a form of visible light communication, using light-emitting diode (LED) and camera as the transmitting receiving device, respectively. In an ISC system, receiver captures optical signals transmitted by blinking LEDs demodulates data captured image. The system can spatially separate noises in image, thus providing superior anti-int...

Objetivou-se analisar o uso procedimentos cirúrgicos eletivos hospital público do Distrito Federal (DF).Métodos: Trata-se uma pesquisa transversal, retrospectiva com abordagem quantitativa realizada prontuários DF. O tamanho amostral foi estimado por meio fó...

AB S T R A C T Official conservation efforts for the northern spotted owl began in the United States in 1975 when it was declared “threatened” in the state of Oregon; efforts continued in a sporadic and unsystematic way through the 1980s. In 1989 the Interagency Scientific Committee (ISC) was established by Congress and charged with the development of a scientifically defensible conservation st...

PURPOSE To determine whether swelling-activated Cl- currents (ICl,swell) observed in isolated nonpigmented ciliary epithelial (NPE) cells contribute to Cl- secretion across the ciliary epithelium. METHODS Ion transport across intact bovine ciliary epithelium was monitored electrically. Native isolated bovine NPE cells were harvested enzymatically. Cell volume changes were measured by calcein-...

Under conditions of high dietary salt intake, prostaglandin E2 (PGE2) production is increased in the collecting duct and promotes urinary sodium chloride (NaCl) excretion; however, the molecular mechanisms by which PGE2 increases NaCl excretion in this context have not been clearly defined. We used the mouse inner medullary collecting duct (mIMCD)-K2 cell line to characterize mechanisms underly...
