The electronic structures of the amino acids containing first row atoms have been determined for the zwitterionic form using an approximate self-consistent field method, partial retention of diatomic differential overlap. Various energetic quantities including certain proton affinities are present as are eigenvalues for the highest occupied and lowest unoccupied molecular orbitals. It is found ...
Voltage-activated ion channels respond to changes in membrane voltage by coupling the movement of charges to channel opening. A K+ channel-specific radioligand was designed and used to determine the origin of these gating charges in the Shaker K+ channel. Opening of a Shaker K+ channel is associated with a displacement of 13.6 electron charge units. Gating charge contributions were determined f...
When irradiated in a transmission electron microscope, plunge-frozen, amorphous water ice specimens accumulate a pattern of static charge that changes dynamically as the specimen is irradiated, and which can deflect the transmitted electrons and blur the resultant micrographs. Here we provide a physical description of this charge accumulation and characterise its dynamic behaviour in the contex...
Background: Given the important role of amino acids in regulating many metabolic pathways of the body and considering the scarcity of markers for the diagnosis of inflammatory bowel disease (IBD) and its differentiation, we aimed to investigate the status of serum amino acids chromatography in children with IBD. Materials and Methods This case-control study was conducted among children with pri...
Cell culture feeds optimization is a critical step in process development of pharmaceutical recombinant protein production. Amino acids are the basic supplements of mammalian cell culture feeds with known effect on their growth promotion and productivity. In this study, we reported the implementation of the Plackett-Burman (PB) multifactorial design to screen the effects of amino acids on the g...
potassium alanate is one of the goal candidates for hydrogen storage during past decades. in this report, initially the density functional theory was applied to simulate the electronic and structural characteristic of the experimentally known kalh4 complex hydride. the relaxation of unit cell parameters and atomic positions was performed until the total residual force reduced less than 0.001ev ...
