Compressed natural gas (CNG) is a substitution of alternative fuel for automotive application with significant environmental advantages as it is the only fuel cheaper than gasoline or diesel, comparatively lower air pollution emissions, lesser CO2 emissions. However, emission of methane is 40% more in CNG fuelled engines compared to gasoline and diesel. With the exponential growth in CNG fuelle...

Cyclic nucleotide-gated (CNG) ion channels mediate cellular responses to sensory stimuli. In vertebrate photoreceptors, CNG channels respond to the light-induced decrease in cGMP by closing an ion-conducting pore that is permeable to cations, including Ca(2+) ions. Rod CNG channels are directly inhibited by Ca(2+)-calmodulin (Ca(2+)/CaM), but the physiological role of this modulation is unknown...

OBJECTIVE To test the hypothesis that very low birth weight infants fed by continuous nasogastric gavage (CNG) would achieve full enteral feedings (100 kcal/kg/d) at an earlier postnatal age and have less feeding intolerance (FI) than infants fed by intermittent bolus gavage (IBG). METHODS Eighty infants were stratified by birth weight (700 to 1000 g and 1001 to 1250 g) and randomized into CN...

Cyclic nucleotide-gated (CNG) channels are important mediators in the transduction pathways of rod and cone photoreceptors. Native CNG channels are heterotetramers composed of homologous A and B subunits. In heterologous expression systems, B subunits alone cannot form functional CNG channels, but they confer a number of channel properties when coexpressed with A subunits. To investigate the im...

Illumination of vertebrate rod photoreceptors leads to a decrease in the cytoplasmic cGMP concentration and closure of cyclic nucleotide-gated (CNG) channels. Except for Ca(2+), which plays a negative feedback role in adaptation, and 11-cis-retinal, supplied by the retinal pigment epithelium, all of the biochemical machinery of phototransduction is thought to be contained within rod outer segme...

Primary cilia are ubiquitous sensory organelles that concentrate transmembrane signaling proteins essential for sensing environmental cues. Mislocalization of crucial ciliary signaling proteins, such as the tetrameric cyclic nucleotide-gated (CNG) channels, can lead to cellular dysfunction and disease. Although several cis- and trans-acting factors required for ciliary protein trafficking and l...

The global policy solution seeks to reduce the usage of fossil fuels and greenhouse gas (GHG) emissions, biogas (BG) represents a solutions these problems. use could help cope with increased amounts waste fuels. Biogas be used in compressed natural (CNG) engines, but engine electronic control unit (ECU) needs modified. In this research, spark ignition (SI) was tested for mixtures hydrogen (volu...
