Reliable simultaneous zymographic method of characterization of cellulolytic enzymes from fungal cellulase complex
(Wiley-Blackwell, Hoboken, 2015)
A method for zymographic detection of specific cellulases in a complex (endocellulase, exocellulase, and cellobiase) from crude fermentation extracts, after a single electrophoretic separation, is described in this paper. ...
Consequences of MnSOD interactions with nitric oxide: Nitric oxide dismutation and the generation of peroxynitrite and hydrogen peroxide
(USA :Taylor & Francis INC, 2007)
The present study demonstrates that manganese superoxide dismutase (MnSOD) Escherichia coli, binds nitric oxide (NO) and stimulates its decay under both anaerobic and aerobic conditions. The results indicate that previously ...
Environmental impact of industrial and agricultural activities to the trace element content in soil of Srem (Serbia)
(Springer, 2019)
This study reports the contents and sources of Cu, Hg, Cr, Ni, Co, Zn, Pb, Cd, As, and B pollution in soil samples from Srem in the province of Vojvodina (Republic of Serbia). They are collected in the vicinity of local ...
Cytotoxic Effect of Wine Polyphenolic Extracts and Resveratrol Against Human Carcinoma Cells and Normal Peripheral Blood Mononuclear Cells
(Mary Ann Liebert Inc, New Rochelle, 2010)
Red and white wine polyphenols have been reported to provide substantial health benefits. In this study, the cytotoxic activity of red and white wine polyphenolic extracts and of resveratrol was evaluated against different ...
In vitro antitumor actions of extracts from endemic plant Helichrysum zivojinii
(Biomed Central Ltd, London, 2013)
Background: The aim of this research was to determine the intensity and mechanisms of the cytotoxic actions of five extracts isolated from the endemic plant species Helichrysum zivojinii Cernjavski & Soska (family Asteraceae) ...
Mixed steroidal tetraoxanes induce apoptotic cell death in tumor cells
(Investigational New Drugs, 2009)
In this study we investigated the antiproliferative activity of six mixed steroidal tetraoxanes against various tumor cell lines, the toxicity against normal peripheral blood mononuclear cells (PBMC), and the mode of HeLa ...
Problem and Solution of UV–Vis Time-Based Measurements of a Chemical System Involving Gas Product: Application to the Bray–Liebhafsky Oscillatory Reaction
(American Chemical Society (ACS), 2021)
Ultraviolet (UV)–visible (Vis) spectroscopy is widely used in all modern laboratories as a routine method of analysis. The monitoring of chemical reactions in an aqueous solution involving a gas product is a demanding task ...
Fourier-transform infrared spectroscopy analysis of mechanochemical transformation kinetics of sodium carbonate to bicarbonate
(ETRAN Society, 2022)
During mechanical activation, qualitative changes that can produce various phenomena occur in the material. In this study, anhydrous sodium carbonate was mechanically activated for 2, 7, 14, and 28 minutes in a vibro mill ...
Mono BN-substituted analogues of naphthalene: a theoretical analysis of the effect of BN position on stability, aromaticity and frontier orbital energies
(Royal Soc Chemistry, Cambridge, 2018)
All isomeric BN isosteres of naphthalene have been studied theoretically, at the B3LYP/6-311+G(d,p) level, in order to investigate the effect of the BN position in a molecule on relative stability, aromaticity and frontier ...
Optimization of solid-state fermentation for enhanced production of pectinolytic complex by Aspergillus tubingensis FAT43 and its application in fruit juice processing
(Oxford University Press, 2023)
The main goal of this study was to examine the efficiency of a newly isolated fungus from quince, Aspergillus tubingensis FAT43, to produce the pectinolytic complex using agricultural and industrial waste as the substrate ...
