1. The physiological actions of HCN and its salts appear to be due (a) to the ease with which HCN molecules penetrate living cells and then ionizing, exert their influence by means of H ions and CN ions; (b) to the weakness of HCN as an acid, which permits at neutrality or at even slight alkalinity the presence of a considerable amount of free HCN molecules in the presence of their salts; (c) t...

Bacterial inoculants are known to possess plant growth promoting abilities and have potential as liquid biofertilizer application. Four phytase producing bacterial isolates (phytase activity in the range of 0.076-0.174 U/mL), identified as Advenella species (PB-05, PB-06, and PB-10) and Cellulosimicrobium sp. PB-09, were analyzed for their plant growth promoting activities like siderophore prod...

Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are subthreshold activated voltage-gated ion channels. In the cortex, these channels are predominantly expressed in dendrites where they significantly modify dendritic intrinsic excitability as well synaptic potential shapes and integration. HCN channel trafficking to dendrites is regulated by the protein, TRIP8b. Additionally, ...

Posttranscriptional control is known to contribute to the regulation of secondary metabolism and virulence determinants in certain gram-negative bacteria. Here we report the isolation of a Pseudomonas aeruginosa gene which encodes a global translational regulatory protein, RsmA (regulator of secondary metabolites). Overexpression of rsmA resulted in a substantial reduction in the levels of extr...

In this research, the effects of HCN adsorption on the surface of the pristine, Ge, P, and GeP doped boron nitride nanotube (BNNTs) are investigated by using density function theory at the B3LYP/6–31G(d, p) level of theory. At the first step, we consider different configurations for adsorbing HCN molecule on the surface of BNNTs. The optimized models are used to calculate the structural, electr...

The large, medium-sized, and small neurons of the dorsal root ganglion (DRG) have different functions in the processing of various senses. Hyperpolarization-activated, cyclic nucleotide-gated channels (HCN) contribute greatly to neuronal excitability. In the present study, which used whole-cell patch clamp techniques and immunohistochemical staining methods, the electrophysiological properties ...

Hyperpolarization-activated and cyclic nucleotide-gated (HCN) channels were first reported in heart cells and are recently known to be involved in a variety of neural functions in healthy and diseased brains. HCN channels generate inward currents when the membrane potential is hyperpolarized. Voltage dependence of HCN channels is regulated by intracellular signaling cascades, which contain cycl...

We report a sensitive search for the HCN(J=2→1) emission line towards SDSS J114816.64+525150.3 (hereafter: J1148+5251) at z=6.42 with the Very Large Array (VLA). HCN emission is a star formation indicator, tracing dense molecular hydrogen gas (n(H2) ≥ 10 4 cm) within star-forming molecular clouds. No emission was detected in the deep interferometer maps of J1148+5251. We derive a limit for the ...

• Formaldehyde present in exhaust gas can react with NH 3 to produce HCN. This reaction was studied by operando DRIFTS on V 2 O 5 /WO -TiO and TiO at 300 °C. formed adsorbed cyanide species, phase HCN detected. Formic acid reacted but did not form species or production does involve formate Hydrogen (HCN) is a highly poisonous that through the between formaldehyde ammonia (NH ) exhaust. While th...
