In lb is research, adsorption of some amino acids and their complenation with manganese (II) ion on carbonnanotube (MWCNT) by using of four relations Langmuir, Freundlich. Temkin and Harkins -Jura imitherms wasinvestigated. From this relations. Freudlich and Temkin relations predict good equilibrium diagram in, isothermcondition. we could compute the theoretical constants by excel software. Hy ...

the adsorption of a number of amino acids on a defected single-walled carbon nanotube (swcnt) isinvestigated by using the density-functional theory (dft) calculations. the adsorption energies andequilibrium distances are calculated for various configurations such as amino acid attaching to defectsites heptagon, pentagon and hexagon in defective tube and also for several molecular orientationswi...

fish larvae have a high requirement of amino acid (aa) for energy production and growth. this study was aimed to increase knowledge of aa profile during feral carp larval ontogeny and estimate larval aa requirements. larvae were collected randomly at 1, 3, 7, 11, 15, 19, 26 and 33 days post hatch for growth and aa analysis. the composition of total aa changed significantly during ontogeny. the ...

the thermodynamic functions such as enthalpy (h), gibbs free energy (g) and entropy (s) of serineand threonine amino acids were theoretically studied at different condition (solvents andtemperatures) by using gussian o3, software. first, the structural optimization of isolated serine andthreonine were done in the gas phase by using the hartree-fock (hf) level of theory with 3-21g, 6-31g and 6-3...

In recent years great progress has been made in understanding the function of ionotropic and metabotropic glutamate receptors; their pharmacology and potential therapeutic applications. It should be stressed that there are already N-methyl-D-aspartate (NMDA) antagonists in clinical use, such as memantine, which proves the feasibility of their therapeutic potential. It seems unlikely that compet...

The impact of PGF2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, Bombyx mori L. were investigated in the present experiment. The effect of PGF2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. The enhanced activity levels of amin...

The existence of multiple receptors for acidic amino acids has been proposed by several authors mainly on the basis of the different sensitivities of amino acid agonists to various antagonists. In the experiments described in the present paper we used two quite different experimental paradigms to define these receptors in slices of rat hippocampus and to investigate their possible relationships...

Modulation of the sensory input can occur within the dorsal horn of the spinal cord where the primary afferent fibers synapse with neurons that transmit to the higher centers. The transmission of the sensory information begins with activation of the peripheral receptors of primary afferent neurons whose cell bodies lie within the dorsal root ganglia and whose central terminals project to second...

BACKGROUND Pulsed radiofrequency (PRF) has been used to treat chronic pain for years, but its effectiveness and mechanism in treating diabetic neuropathic pain are still unexplored. The aim of this study was to elucidate the modulation of diabetic neuropathic pain induced by streptozotocin and the release of spinal excitatory amino acids by PRF. METHODS Diabetes was induced by intraperitoneal...
