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 ... -
Homo- and heteronuclear complexes of a new, vicinal dioxime ligand
(Springer International Publishing Ag, 2007)A new symmetrical vicinal dioxime, N,N'-bis-{4-[[(2-hydroxyphenyl)methylene]hydrazinecarbonyl]phenyl}diaminoglyoxime (LH4), was prepared by reacting anti-dichloroglyoxime with salicylaldehyde 4-aminobenzoylhydrazone. The ... -
Influence of osmotic and metal stresses on nitrogenase activity of cyanobacteria isolated from paddy fields
(Academic Journals, 2007)Samples were collected from paddy fields in Corum-Turkiye. Nitrogen-free BG-11 medium was used for isolation of nitrogen fixing cyanobacteria. Acetylene reduction technique was used to determine the effects of different ... -
Effects of antecedent topography on reefal carbonate deposition: Early-Middle Miocene of the Adana Basin, S Turkey
(Pergamon-Elsevier Science Ltd, 2007)Early-Middle Miocene reefal limestones and other shallow marine sedimentary sequences were important components of Neogene Basins (especially the Adana Basin) in Southern Turkey. The most important controlling factors of ... -
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 ... -
Comparative studies for the determination of uranyl ion adsorption onto Interpenetrating Polymer Networks (IPNs)
(Springer, 2007)The adsorption of uranyl ions from aqueous solutions was studied by using three different measurement techniques. Results obtained by gamma-spectrometry, UV-visible spectrophotometry and gravimetry have been compared. It ... -
Some physical, wood polymer biological, mechanical, and fire properties of composite (WPC) pretreated with boric acid and borax mixture
(Elsevier Sci Ltd, 2007)Wood polymer composite (WPC) was obtained by vinyl monomers such as styrene (ST), methylmethacrylate (MMA), and their mixture (50:50; volume:volume) of treated sapwood of Scots pine (Pinus sylvestris L.). Boric acid (BA) ... -

Application of extracts from the poisonous plant, Nerium Oleander L., as a wood preservative
(Academic Journals, 2007)The antifungal properties of poisonous plant extracts from oleanders ( Nerium oleander L.) were determined when used as a wood preservative. The extract was prepared from oleanders leaves and flowers in 96% ethyl alcohol. ... -
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 ... -
An Analytical Network Process (ANP) evaluation of alternative fuels for electricity generation in Turkey
(Elsevier Sci Ltd, 2007)In this paper, we present an Analytical Network Process (ANP) model to determine the best fuel mix for electricity generation in Turkey from a sustainable development perspective. The proposed model is implemented in two ... -
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 ... -
Cultivation of Agaricus bisporus on some compost formulas and locally available casing materials. Part I: Wheat straw based compost formulas and locally available casing materials
(Academic Journals, 2007)Three compost formulas; wheat straw based and using different activator materials such as wheat brain, chicken manure, and pigeon manure were used for Agaricus bisporus cultivation. Locally available casing materials such ... -
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 ... -
Change of thermotropic properties in liquid crystal with multiple phase transitions: Surface "aging" effect
(Elsevier Science Bv, 2007)The effect of surface "aging" on thermotropic properties of polymorphic mesogen, 4-butoxyphenylester of 4-decyloxybenzoic acid (BPEDBA) which exhibits the smectic G, smectic C, smectic A, and nematic mesophases has been ... -
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 ... -
