A preliminary study on determination of Aphanius chantrei's feeding behaviour on mosquito larvae
(Elsevier, 2007)In this study, Aphanius chantrei's behaviour of feeding on mosquito larvae has been determined under experimental conditions. In groups that have different sizes (first group 27 mm; second group 40 mm; third group 47 mm), ... -
Decolourization and removal of some organic compounds from olive mill wastewater by advanced oxidation processes and lime treatment
(Springer Heidelberg, 2007)Background. Olive mill wastewater (OMW) generated by the olive oil extracting industry is a major pollutant, because of its high organic load and phytotoxic and antibacterial phenolic compounds which resist biological ... -
Inhibition of quorum sensing-regulated behaviors by Scorzonera sandrasica
(Springer, 2007)Many Gram-negative bacteria use N-acyl homoserine lactone signal molecules to monitor their own population density and coordinate gene regulation in a process called quorum sensing (QS). Increasing evidence implies that ... -
alpha-glucosidase based bismuth film electrode for inhibitor detection
(Elsevier, 2007)A biosensing system based on (alpha-glucosidase (AG) activity was developed by using bismuth film modified glassy carbon electrode (BiFE). AG enzyme was immobilized on the BiFE by means of gelatin membrane and the activity ... -
Screening of antioxidant activity of three Euphorbia species from Turkey
(Elsevier Science Bv, 2007)Euphorbia acanthothamnos, E. macroclada and E. rigida were investigated for their antioxidant activity. The antioxidant potential of extracts of E. acanthothamnos, E. macroclada and E. rigida was evaluated using different ... -
Translational regulation of human methionine synthase by upstream open reading frames
(Elsevier, 2007)Methionine synthase is a key enzyme poised at the intersection of folate and sulfur metabolism and functions to reclaim homocysteine to the methionine cycle. The 5' leader sequence in human MS is 394 nucleotides long and ... -
Gentamicin release from photopolymerized PEG diacrylate and pHEMA hydrogel discs and their in vitro antimicrobial activities
(Taylor & Francis Inc, 2007)Hydrogels based on poly(ethylene glycol)-diacrylate (PEG-DA) and 2-hydroxyethyl methacrylate (HEMA) were polymerized with cross-linking agent ethylene glycol diacrylate (EGDMA) under mild photoinitiating conditions. PEG-DA ... -
Comparison of four methods for the estimation of intracranial volume: A gold standard study
(Wiley, 2007)Investigators can infer how much reduction in volume has occurred since brain volume was at its peak, by combining measures of brain volume with measures of intracranial volume (ICV). Several methodologies have been proposed ... -
Melatonin prevents inflammation and oxidative stress caused by abdominopelvic and total body irradiation of rat small intestine
(Assoc Bras Divulg Cientifica, 2007)We investigated the day-night differences in intestinal oxidative-injury and the inflammatory response following total body (TB) or abdominopelvic (AP) irradiation, and the influence of melatonin administration on tissue ... -
Chionaeosides A-D, triterpene saponins from Paronychia chionaea
(Amer Chemical Soc, 2007)Four new triterpenoid saponins, chionaeosides A-D (1-4) were isolated from the roots of Paronychia chionaea. On the basis of their spectroscopic data, the structures of the new saponins were established as 3-o-alpha-L-ar ... -
Herminiimonas saxobsidens sp nov., isolated from a lichen-colonized rock
(Microbiology Soc, 2007)A Gram-negative, rod-shaped, non-spore-forming bacterium (strain NS11(T)) was isolated from a lichen-colonized rock surface. On the basis of 16S rRNA gene sequence similarity, strain NS11(T) was shown to belong to the ... -
