Orchidectomy affects the innervation of the rat thymus
(Gordon Breach Sci Publ Ltd, Reading, 1999)
To assess a putative role of the neural pathways in transfer of information from the gonads to the thymus, adult AO rats were orchidectomized (ORX) or sham ORX (controls); sacrificed 1, 3, 7, or 15 days later and their ...
Spectrophotometric and electrochemical study of protolytic equilibria of some oximes-acetylcholinesterase reactivators
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Newly synthesized oximes, mono and bis imidazole derivatives, which promise to be more effective acetylcholinesterase reactivators than standard antidotes used, were investigated by spectrophotometric and electrochemical ...
Simple and rapid method for the measurement of nitrite and nitrate in human plasma and cerebrospinal fluid by capillary electrophoresis
(Elsevier Science BV, Amsterdam, 1999)
Nitrite and nitrate levels in physiological fluids are commonly used as an index of nitric oxide production. We developed simple and rapid method for the determination of these anions by capillary zone electrophoresis ...
Determination of some insect repellents in cosmetic products by high-performance thin-layer chromatography
(Elsevier Science BV, Amsterdam, 1999)
A simple and reliable thin-layer chromatographic method for the determination of N,N-diethyl-m-toluamide (DEET) and dimethyl phthalate (DMP) in raw material and cosmetic products was developed and validated. A benzene-diethyl ...
Quantity and composition of essential oil of the wild plant Nepeta nuda L. from Yugoslavia
(Journal of Essential Oil Research, 1998)
The aerial parts of the wild plant Nepeta nuda L. collected in Serbia and the Durmitor region contained respectively 0.67–0.70% and 0.4% oil. Each oil was analyzed by GC and GC/MS. The main constituent was 1,8-cineole; ...
Apolipoprotein E polymorphism and severity of angiographically verified coronary artery disease
(Društvo medicinskih biohemičara Srbije i Crne Gore, Beograd i Univerzitet u Beogradu - Farmaceutski fakultet, Beograd, 1999)
Apolipoprotein E is an important genetic determinant of serum lipoprotein concentrations and coronary artery disease risk. The apo E polymorphism is a major determinant of interindividual variation in the initiation and ...
Effect of increasing the bidentate chelate ring size in Co(III) complexes on their behavior in salting-out TLC on different adsorbents
(Springer Hungarica Kiado Kft, Budapest, 1999)
The effect of enlargement of the chelate ring size in Co(III) complexes containing bidentate aminocarboxylato and/or diamine ligands on their R-F values in salting-out chromatography has been investigated on thin layers ...
Use of ANN modelling in structure-retention relationships of diuretics in RP-HPLC
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
Structure-retention relationship study, conducted by RP-HPLC, was used to investigate physical chemical parameters related to the RP retention times of amiloride, hydrochlorothiazide and methyldopa in order to predict the ...
Determination of metal traces in wine by argon stabilized d.c. arc
(Springer Verlag, New York, 1999)
A spetroscopic method for the determination of metal traces (Mn, Cu, Fe) in wine has been developed based on argon stabilized d.c. are plasma at atmospheric pressure. The experimental conditions were optimized using lateral ...
