This is the first report ever on the nuclear spin selective CaCa isotope effect expressed in the Calcium affected enzymatic ATP synthesis. Once the creatine kinase (CK) catalytic sites were loaded with Ca , the resulting enzyme activity goes up (2.0±0.3 – fold) compared to the CKdirected ATP synthesis rate occurred in the presence of nonmagnetic, spinless, Ca nuclei. The effect manifests itsel...
in this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited fecu/cu thin films was investigated. the films were deposited on au2pdag/glass substrates using electrodeposition technique in potentiostatic control. the magnetic fields of 5000 and 7000 oe were applied on deposition bath during deposition. two series of thin films were prepared...
The influence of isotopically enriched magnesium on the creatine kinase catalyzed phosphorylation of adenosine diphosphate is examined in two independent series of experiments where adenosine triphosphate (ATP) concentrations were determined by a luciferase-linked luminescence end-point assay or a real-time spectrophotometric assay. No increase was observed between the rates of ATP production w...
basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...
Isotope effects are one of the most powerful kinetic tools for determining enzyme mechanisms. There are three methods of measurement. First, one can compare reciprocal plots with labeled and unlabeled substrates. The ratio of the slopes is the isotope effect on V/K, and the ratio of the vertical intercepts is the isotope effect on V(max). This is the only way to determine V(max) isotope effects...
Results The resulta showed that 3,4-DHC with dose of 25mg/kg induced significant antinociception and anti-inflammation compared with control group. In additon the effect of DHC was higher in the chronic phase of formalin test, therefore it seems that DHC has better anti-inflammatory effect rather than analgesic effect. The dose of 25 mg/kg of DHC induces significant analgesia in hot plate test ...
The hollow inside of single-wall carbon nanotubes (SWCNT) provides a unique degree of freedom to investigate chemical reactions inside this confined environment and to study the tube properties. It is reviewed herein, how encapsulating fullerenes, magnetic fullerenes, C isotope enriched fullerenes and organic solvents inside SWCNTs enables to yield unprecedented insight into their electronic, o...
BACKGROUND Chronic kidney disease (CKD) is associated with increased left ventricular (LV) mass and arterial stiffness. In a previous trial, spironolactone improved these end points compared with placebo in subjects with early-stage CKD, but it is not known whether these effects were specific to the drug or secondary to blood pressure lowering. AIM The aim was to investigate the hypothesis th...
The seeds of Peganum harmala L. (Pgh) (Zygophyllaceae) have been used in Moroccan traditional medicine to treat various diseases. The objective of this study was to investigate the analgesic effect of ethyl acetate (EAE), butanolic (BE) and aqueous (AqE) extracts of seeds of Peganum harmala and to elucidate the possible action mechanism of each extract. The antinociceptive action was assayed in...
