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. ...
Antioxidant system in human erythrocytes involved in radioprotection
(The Israel Society for Biochemistry and Molecular Biology, 1991)
The aim of this work was the investigation of the influence of ionizing radiation on the erythrocyte antioxidant system and metabolism. The erythrocyte antioxidative enzymes, GSH/GSSG ratio, as well as selenium concentrations ...
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 ...
Highly oxygenated guaianolides from Anthemis cretica subsp. cretica
(Elsevier, 1999)
Two new guaianolides, i.e. anthemolide B and 8-O-angeloyl-9-O- acetylanthemolide B, in addition to 12 known closely related guaianolides were identified in the aerial parts of the flowering plant Anthemis cretica subsp. cretica.
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, ...
Mathematical modelling and simulation of drawing thin glass sheet from a rectangular preform
(Society of Glass Technology, 1998)
A mathematical model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
Multiwavelength fiber-optic temperature sensor for cryogenic to high temperatures
(IEEE, Piscataway, NJ, United States, 1995)
The results of an investigation of an autoreferencing fiber-optic temperature sensor based on a CdTe single crystal are presented. A method for extending the working temperature range is proposed. A special sensor design ...
Effect of sulfur oxides on surface state and carbon monoxide oxidation activity of CuxZnl-xCr204 mixed oxides
(Elsevier B.V., 1994)
The effect of mixed sulfur oxides pretreatment on the surface state and carbon monoxide oxidation activity of CuxZn1−xCr2O4 mixed oxides, has been investigated using X-ray photoelectron spectroscopy (XPS) and kinetic ...
Liquefaction behaviour of Kolubara soft brown coal
(Elsevier B.V., 1994)
The behaviour of Kolubara soft brown coal during direct liquefaction by catalytic hydrogenation was studied and was compared with the Banovići brown coal investigated previously. A sample of washed and dried coal was ground ...
Direct hydroliquefaction of a low rank soft brown coal
(Elsevier B.V., 1998)
The behaviour of the soft brown coal from the Kostolac Mine (Serbia, Yugoslavia) was investigated during hydroliquefaction carried out in a batch reactor by direct catalytic hydrogenation of the pulverized coal (- 160 μm) ...
