Occurrence of resistance to antibiotics, metals, and plasmids in clinical strains of Staphylococcus spp
(Elsevier Science Inc, 2003)Background. Presence of staphylococci resistant to antibiotics is of concern, as is the possible spread of resistance determinants among Staphylococcus species. During the past several years, a series of staphylococcal ... -
Isolation and characterization of antioxidant phenolic compounds from the aerial parts of Hypericum hyssopifolium L. by activity-guided fractionation
(Elsevier Sci Ireland Ltd, 2003)Dried methanol extract of Hypericum hyssopifolium subsp. elongatum var. elongatum was dissolved in distilled water, and then fractioned by re-extracting with petroleum ether, chloroform, and ethyl acetate, subsequently. ... -
Heavy metal biosorption by biomass of Ochrobactrum anthropi producing exopolysaccharide in activated sludge
(Elsevier Sci Ltd, 2003)The removal of chromium, cadmium and copper, toxic metals of high environmental priority due to their toxicity, from dilute aqueous solutions has been studied in the present work, applying a dead exopolysaccharide producing ... -
Phytosociological investigations of Pinus pinea L., forests in the North-East Anatolia region (Trabzon and Artvin - Turkey)
(Pakistan Botanical Soc, 2003)In this study phytosociological structure of Pinus pinea L., forests that occurs in Trabzon and Artvin provinces in the East-Black Sea region in Turkey has been investigated. From the phytogeographical view point, it is ... -
A new host and two new genera for the fungal flora of Turkey
(C S I R O Publishing, 2004)Cronartium quercuum causing leaf rust of Quercus coccifera and Trimmatostroma betulinum on Salix alba are recorded for the first time in Turkey. These represent the first records of the genera Cronartium and Trimmatostroma ... -
Identification and characterization of a glycosaminoglycan recognition element of the C chemokine lymphotactin
(Amer Soc Biochemistry Molecular Biology Inc, 2004)Chemokine-mediated recruitment of leukocytes in vivo depends on interactions with cell surface glycosaminoglycans. Lymphotactin, the unique member of the "C" chemokine subclass, is a highly basic protein that binds heparin, ... -
Effects of supersymmetric CP phases on chargino-pair production via the Drell-Yan process at the CERN LHC
(Amer Physical Soc, 2004)We compute the rates for pp annihilation into chargino pairs via the Drell-Yan process taking into account the effects of supersymmetric soft phases, at a proton-proton collider. In particular, the phase of the mu parameter ... -
Determination of malathion and diazinon resistance by sequencing the Md alpha E7 gene from Guatemala, Colombia, Manhattan, and Thailand housefly (Musca domestica L.) strains
(Maik Nauka/Interperiodica/Springer, 2004)Organophosphate (OP) insecticides (parathion/diazinon) resistance in housefly (Musca domestica L.) is associated with the change in carboxylesterase activity. The product of alphaE7 gene, which is a member of alpha-esterase ... -
Selective extraction of iron(III) from aqueous nitrate solution in the presence of cobalt(II), copper(II) and nickel(II) ions using BiS(Delta(2)-2-imidazolinyl)-5,5 '-dioxime
(Japan Soc Analytical Chemistry, 2004)The feasibility of using bis(Delta(2)-2-imidazolinyl)-5,5'-dioxime (H2L) for the selective extraction of iron(III) from aqueous solutions was investigated by employing an solvent-extraction technique. The extraction of ... -
Biosorption of chromium(VI), cadmium(II) and copper(II) by Pantoea sp TEM
(Elsevier Science Sa, 2004)Microorganisms and microbial products can be highly efficient bioaccumulators of soluble and particulate forms of metals, especially from dilute external solutions, and microbe-related technologies may provide an alternative ... -
