In this research, the interactions of HCN gas with pristine, Ga-, N- and GaN-doped of boron phosphide nanotube (BPNTs) were investigated by using density function theory (DFT). The structure, electrical and NQR parameters, quantum descriptors involving energy gap, global hardness, global softness, electrophilicity, electronic chemical potential and electronegativity were calculated. The adsorpt...

background and objectives: nitrogen fixation is a biological process, which provides atmospheric nitrogen in usable form for plants, and satisfies the plants n requirement and can replace chemical fertilizers in high proportion. on the other hand, calcareous and high ph soils have usually small amounts of nutrients in available forms and use of plant growth promoting rhizobacteria can increase ...

The hyperpolarization-activated, cyclic nucleotide-modulated (HCN) channel gene family is known to contribute significantly to cardiac pacemaking via pacemaker currents. To date, there are four mammalian HCN isoforms (HCN1–4) identified. The importance of HCN channel function to normal cardiac automaticity in mice was recently corroborated in humans diagnosed with idiopathic sinus node dysfunct...

Ion channels play a major role in the regulation of T cell function in health and disease. In a computer-based model, established to simulate T cells’ membrane potential (VM) generation, we discovered a discrepancy between the simulation and patch-clamp recordings. The predicted VM was more hyperpolarized than the measured VM, indicating that a yet unknown, depolarizing ion current might ...

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...

Hydrogen cyanide (HCN) has been recognized as a potential biomarker for non-invasive diagnosis of Pseudomonas aeruginosa infection in the lung. However, the oral cavity is a dominant production site for exhaled HCN and this contribution can mask the HCN generated in the lung. It is thus important to understand the sources of HCN production in the oral cavity. By screening of oral anaerobes for ...

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, ...

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...
