Synthesis and oxidative transformations of 5-hydroxy-5α-cholest-8-en-3β-yl acetate
(Serbian Chemical Society, 1997)
5-Hydroxy-5α-cholest-8-en-3β-yl acetate (8) (prepared in 6 steps starting from 7-dehydrocholesteryl acetate (1) was transformed with ruthenium tetroxide to 5-hydroxy-8,9-dioxo-8,9-seco-5α-cholestan-3β-yl acetate (9). ...
Erythrocyte metabolism in insulin-induced hypoglycemia
(Bulgaria : Balkan Federation of Clinical Laboratory, 1996)
Insulinomas are pancreatic tumors associated with hyperinsulinism and hypoglycaemia. The effects of long-term hypoglycaemia, caused by hyperinsulinism in insulinoma patients, on erythrocyte metabolism, were investigated. ...
Content of NO reactive -SH and Superoxide dismutase activity in CSF of ALS patients
(8th International Symposium on ALS/MND, Glasgow, 1997)
The aim of this study was to investigate the content of -SU groups and SOD activity m cerebrospinal fluid (CSF) both in ALS patients and control group, as well as to perform an in vitro lest for CSF NO binding capacity, ...
Ceruloplasmin, copper and zinc in pulmonary emphysemia
(Bulgaria : Balkan Federation of Clinical Laboratory, 1996)
We analyzed the blood samples from 20 patients with global respiratory failure (10 males, mean age 56±7 yrs. and 10 females, mean age 60±5 yrs.). All patients were heavy cigarette smokers, in average 33±8 pack-years.
Spirometrics ...
X-Ray Analysis in the Optimization of the Sintering Process of SmCo5 Magnets
(Sintering Society, 1997)
The content of the SmCo5 phase, as the carrier of magnetic properties, was controlled by X-ray diffraction analysis. The content of the SmCo5 phase, as a function of sintering time and temperature, under constant heat ...
The influence of solidification rate on the microstructure and distribution of solute during the solidification of Al-Cu alloy / Uticaj brzine očvršćavanja na mikrostrukturu i raspodelu primesa tokom očvršćavanja legure Al-Cu
(Savez inženjera metalurgije Jugoslavije, 1999)
In this paper investigation of the influence of solidification rate on the microstructure and distribution of solute during the solidification of Al-2.2%Cu by Vertical Bridgman method was performed. The experiments were ...
Electrochemical Deposition and Phase Structure of Electrodeposited Ni-W Alloys / Elektrohemijsko taloženje i fazna struktura legura Ni-W
(Serbian Chemical Society, 1999)
The induced deposition of W in the presence of iron-group metals has been known for a long time without a proper understanding of the mechanism of codeposition. Hints were made by several authors, concerning primarily a ...
The Effect of Deposition Process Exchange Current Density on the Thin Metal Film Formation on Inert Substrate / Uticaj gustine struje izmene na proces taloženja tankih filmova metala na nesrodnim podlogama
(Belgrade : Serbian Chemical Society, 1997)
The initial stage of thin surface metal film formation on inert substrate is considered. The simultaneous action of both active centers and nucleation exclusion zones was taken into consideration when discussing the ...
Determination of nonenzymatically protein-bound carbohydrates in serum by phenol-sulfuric acid
(Association of Greek Chemists, 1998)
In this work a new spectrophotometric method for determination of nonenzymatically scrum protein-bound carbohydrates by phenol-sulfuric acid [5] as reagent, was used. All relevant parameters as the conditions of hydrolysis ...
The Characterization of Sintered SmCo5 Magnets
(Association for ETRAN Society, 1999)
During the investigation and design of laboratory model of a Sintered SmCo5 magnet, a group of methods for characterizing sintered and heat treated magnets was defined. The direct dependence of the magnetic properties of ...
