Electroretinographic evaluation of spectral sensitivity in yellow and silver eels (Anguilla anguilla)
(Cambridge Univ Press, New York, 1998)
Although differences in visual pigments between developmental stages of the European eel are well known, the expected differences in spectral sensitivity have not been demonstrated at the electrophysiological level. In ...
Electrophysiological and spectral properties of second-order retinal neurons in the eel
(Elsevier Science Inc, New York, 1998)
Several classes of second-order neurons have been electrophysiologically explored in immature European eels (Anguilla anguilla) from two distant and ecologically different localities tin Russia and Yugoslavia). The majority ...
Effects of the air pollutant SO2 on leaves: Inhibition of sulfite oxidation in the apoplast by ascorbate and of apoplastic peroxidase by sulfite
(American Society of Plant Biologists, 1992)
After SO2 has entered leaves of spinach (Spinacia oleracea) through open stomata and been hydrated in the aqueous phase of cell walls, the sulfite formed can be oxidized to sulfate by an apoplastic peroxidase that is ...
Detection of monodehydroascorbic acid radical in sulfite-treated leaves and mechanism of its formation
(Japanese Soc Plant Physiologists, Kyoto, 1998)
The aim of the present study is to detect the monodehydroascorbic acid (MDA) radical in broad bean (Vicia faba L.) leaves which were treated by vacuum-infiltration in Na2SO3 solution and subsequent centrifugation ...
Feeding habits of huchen Hucho hucho (Salmonidae) fry in the River Tresnjica, Yugoslavia
(Taylor & Francis Ltd, Abingdon, 1998)
About 10 000 huchen larvae, obtained by artificial spawning, were introduced on 28 May 1995 into the River Tresnjica, a tributary to the River Drina, using procedures applied routinely by local fishing associations. During ...
Study of photochemical reactions of coniferyl alcohol. II. Comparative structural study of a photochemical and enzymatic polymer of coniferyl alcohol
(American Society for Photobiology, 1998)
The structure of the polymer synthesized by UV irradiation of coniferyl alcohol was studied, using UV-visible, Raman, IR, LH-NMR and C-13-NMR spectroscopy. The photochemical polymer was compared with the structure of the ...
Spontaneous ultraweak, bioluminescence in plants: Origin, mechanisms and properties
(R and D print, 1998)
An analysis of theoretical knowledge and experimental results of ultraweak luminescence (UWL) is provided. The role of excited state of molecules and free radicals, formed in various biochemical reactions, in UWL is ...
Synthesis and deposition of ZnO based particles by aerosol spray pyrolysis
(Elsevier Science Sa, Lausanne, 1997)
Spray pyrolysis was used for the deposition of well defined submicronic to nanosize particles based on ZnO. The influence of the temperature in the range from 345 to 1165 K, solution concentration (0.004 and 1.5 mol dm(-3)) ...
