Covalent glycophospholipid binding to hemoglobin. A new post-translational modification occurring in erythrocytes exposed to insulin
(Serbian Chemical Society, 1996)
In this work a novel hitherto unrecognised hemoglobin (Hb) fraction, HbA1x, which we detected previously in hemolysates of erythrocytes exposed to high concentration of insulin under hypoglycemic conditions, both in vivo ...

The identification of nine known guaianolides, i.e., solstitialin A, its 13-acetate, linichlorin B, cynaropicrin, centaurepensin (chlorohyssopifolin A), 17-epi-centaurepensin, 19-desoxychlorojanerin, 11ß,13-dihydrodesacy ...
An improved approach to B-norsteroids: An one-pot preparation of 3β-acetoxy-5-oxo-5,6-seco-cholestan-6-oic and 3β-acetoxy-5,17-dioxo-5,6-seco-androstan-6-oic acids
(Serbian Chemical Society, 1998)
A simple one-put procedure for the synthesis of the 5,6-seco-steroidal acids 9a,b in described in this paper. It consists of the epoxidation of the ▲ 5 -steroids, i.e., cholesteryl acetate (8a) and 17-oxo-aandrost-5-en-3β-yl ...
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). ...
Stereoselective transformation of cyclodecene-1,4-dione systems, derived from steroids, to the corresponding spiro-g-lactones. A semiempirical MO Study
(MDPI, 1999)
The thermal and acid-catalyzed intramolecular rearrangement of the (Z)- and (E)-cyclodecene-1,4-dione compounds deriving from steroids, 2a,b and 3a,b, respectively, proceeds stereoselectively to give the corresponding ...
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 ...
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 ...
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 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 ...
