Distribution of the Asiatic cyprinid Pseudorasbora parva in Serbia and Montenegro
(Wiley, Hoboken, 2004)
The first record of Pseudorasbora parva in the Balkan region was in 1977 in Sasko Lake, Montenegro and in 1978 it was found in Serbia. Since then, this species has spread to almost all lowland rivers and has become a ...
P-31 NMR spectroscopy and polarographic combined study of erythrocytes treated with 5-fluorouracil - Cardiotoxicity-related changes in ATP, 2,3-BPG, and O-2 metabolism
(New York Acad Sciences, New York, 2005)
Antineoplastic drug 5-fluorouracil (5-FU) frequently shows cardiotoxic effects, the mechanism of which has not yet been elucidated. The objective of the present study was to explore effects of 5-FU on metabolism of ATP, ...
Ascorbic acid and the oxidative processes in pea root cell wall isolates - Characterization by fluorescence and EPR spectroscopy
(New York Acad Sciences, New York, 2005)
A comparative fluorescence and oxygen radical-sensitive spin trap EPR spectroscopic study of isolated cell walls (with proteins or deproteinated), in the presence and absence of ascorbate and H2O2 is presented. Fluorescence ...
Influence of photic environment on the form of the fish electroretinographic off-response
(New York Acad Sciences, New York, 2005)
Scotopic electroretinogram of dogfish shark (Scylliorhinus canicula) and eel (Anguilla anguilla) is characterized by a negative off-response, changing in sign under photopic condition. It increased under the effect of ...
Mycorrhiza formation enhances adaptive response of hybrid poplar to drought
(New York Acad Sciences, New York, 2005)
Mycorrhized and nonmycorrhized plants of hybrid poplar (Populus tremula L. x Populus tremuloides Mich) were cultivated in petri dishes until the amount of water became limiting (detected by a decrease of photosynthetic ...
A novel approach to modeling and simulation of NTC thick-film segmented thermistors for sensor applications
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2007)
This paper describes the design, modeling, simulation, and fabrication of thick-film segmented thermistors. These thermistors were printed on alumina using negative temperature coefficient 3K3 paste, composed of nanometer ...
The effect of anoxia on PolyP content of Phycomyces blakesleeanus mycelium studied by P-31 NMR spectroscopy
(New York Acad Sciences, New York, 2005)
The effect of anoxia and the respiratory chain inhibitors azide and cyanide on the polyphosphate content of Phycomyces was studied by in vivo (31)p NMR spectroscopy. Anoxia was manifested by a decrease of core polyphosphates ...
Photopic vision in eels - Evidences of color discrimination
(New York Acad Sciences, New York, 2005)
Several classes of second-order retinal neurons have been studied electrophysiologically in European eel (Anguilla anguilla) from two different localities, Lake Seliger in Russia and the coastal waters of the Adriatic Sea ...
Vitamin C contents modulate defence and plant development via transcriptional regulation.
(Elsevier Science Inc, New York, 2002)
Gradient analysis reveals a copper paradox on floodplain soils under long-term pollution by mining waste
(Elsevier, Amsterdam, 2012)
Arable alluvial soils are a globally important resource under increasing pressure from both industrial pollution and intensified agricultural land use. Quality of agricultural soils is ultimately defined by crop yields; ...
