Effects of microwave treated substrate on pepsin reaction kinetics
(Society of Physical Chemists of Serbia, 2008)
Microwave (MW) irradiated bovine serum albumin (BSA) and bromphenol blue (BPB) complex was used as substrate for the assay of pepsin by kinetic method. Decreased reaction velocity under absorbed MW energy and constant ...
Influence of external magnetic field on the electrolytic hydrogen evolution on different cathode materials
(Society of Physical Chemists of Serbia, 2008)
The correlation between magnetic properties of cathodic materials on the evolution of hydrogen and the separation factor was found. The cathodes were pure Ni and cathodes with the electrocatalytic coatings of following ...
The level of CuZn superoxide dismutase in liver of rats exposed to acute, chronic or combined stress
(Society of Physical Chemists of Serbia, 2006)
The CuZn superoxide dismutase (CuZnSOD) protein expression in liver of Wistar male rats exposed to acute (immobilization or cold), chronic (isolation, crowding or daily swimming) or combined stressors was followed by Western ...
On the spin density wave electron gas
(Society of Physical Chemists of Serbia, 2004)
The possibility of a non-trivial ground state of an electron gas in metal featuring a spin density wave (SDW) was widely discussed. We investigated the collective spectrum (CS) of a spin density wave electron gas using the ...
Effect of EDTA on the inhibition of rat myometrial ecto-ATPase activity in the presence of heavy metal ions II. cadmium
(Society of Physical Chemists of Serbia, 2006)
The effects of ethylenediamine tetraacetic acid (EDTA) on the CdCl2 cell toxicity was examined on rat myometrium. Activity of plasma membrane ecto-ATPase, as modulator of purinergic signaling in the presence of increasing ...
Study of C−H⋅⋅⋅π interactions with pyrrole and chelate rings in metal-porphyrin complexes
(Society of Physical Chemists of Serbia, 2006)
The Cambridge Structural Database (CSD) was screened in order to find and investigate specific C−H⋅⋅⋅π interactions between C−H groups and two types of rings with delocalized π-bonds that exist in porphyrin: pyrrole and ...
Modulation of Ca2+ ion flux through mitochondrial membrane of the rat brain steam synaptosomes by 17β-estradiol
(Society of Physical Chemists of Serbia, 2008)
In the present study the modulation of Ca2+ ion flux in the synaptosomal mitochondria isolated from the ovariectyomized rat Brain Steam and the possible roll of membrane bound estradiol was examined. Physiological ...
The evaluation of radionuclides removal using clinoptilolite, hydroxyapatite and their mixtures
(Society of Physical Chemists of Serbia, 2008)
The sorption properties of clinoptilolite and hydroxyapatite towards Cs1+, Co2+, and Sr2+ ions were compared, under the same experimental conditions. Cs1+ was preferably sorbed by natural clinoptilolite. Conversely, synthetic ...
Mechanically activated ceria
(Society of Physical Chemists of Serbia, 2004)
The reduction of comercial and mechanically activatedCeO2 powder at 1200 °C in an argon atmosphere was examined by XRD. Mechanical activation of oxide powder was performed by milling in a vibratory mill for different lengths ...
Adsorption isotherms of chloroform on macroporous copolymers determined by inverse gas chromatography
(Society of Physical Chemists of Serbia, 2004)
The inverse gas chromatography (IGC) under finite surface coverage conditions was used for the determination of adsorption isotherms of chloroform on macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol ...
