The gametes and embryos of Paracentrotus lividus were exposed to purified and nonpurified effluents of a paper plant together with tap water. The toxicity of purified and non-purified effluents were resembled. Most severe pathologic cases were evident with the tap water. In general, developmental defects were increased with decreasing salinity at all test solutions.

Effect of suppressive DNA on CpG-induced immune activation. Yamada, H; Gursel, I; Takeshita, F; Conover, J; Ishii, KJ; Gürsel, Mayda; Takeshita, S; Klinman, DM (The American Association of Immunologists, 2002-11-15) Bacterial DNA and synthetic oligodeoxynucleotides (ODN) containing unmethylated CpG motifs stimulate a strong innate immune response. This stimulation can be abrogated by either removing the CpG DNA or adding inhibitory/suppressive motifs. Suppression is dominant over stimulation and is specific for CpG-induced immune responses (having no effect on LPS- or Con A-induced activation). Individual cells noncompetitively internalize both stimulatory and suppressive ODN. Studies using ODN composed of both stimula...
Effect of salt stress on antioxidant defense systems of sensitive and resistance cultivars of lentil(Lens culinaris M.) Cicerali, Işın Nur; Yücel, Ayşe Meral; Department of Biotechnology (2004) In this study, two lentil cultivars (Lens culinaris, Medik.) (ILL5582-salt tolerant and ILL590) were characterized and compared due to their NaCl susceptibility and antioxidant mechanism was examined under laboratory conditions. Physiological parameters such as wet-dry weight, root-shoot lengths, cell membrane stability, lipid peroxidation in terms of malondialdehyde (MDA), H2O2, proline contents were determined. The activities of antioxidant enzymes such as superoxide dismutase (SOD: EC 1.15.1.1), catalase...
Impact of the recent oil spill (Nassia) in bosphorus (Turkey) on developmental stages of sea urchin Paracentrotus lividus Lam. eggs Uysal, Zahit; Yilmaz, K (1997-09-01) The gametes and embryos of Paracentrotus lividus were exposed to various dilutions of water-soluble fractions (wsf) of oil prepared at two different temperatures (18 degrees C and 24 degrees C) to observe developmental defects during fertilization and larval stages up to pluteus. Emulsions at 24 degrees C have yielded better fertilization rates and development of larvae against emulsions at 18 degrees C. In general, developmental defects were increased with increasing wsf of oil and its toxicity decreased w...
ANALYSIS OF PLASMIDS MEDIATING ANT (2'') AND AAC(3)-II BASED GENTAMICIN RESISTANCE IN CLINICAL ISOLATES OF ENTEROBACTERIACEAE Kocabıyık, Semra (Elsevier BV, 1989-07-01) The genetics of ANT(2″) and AAC(3)-II mediated gentamicin resistance in Gram-negative bacteria obtained from Hacettepe University Hospital in Turkey, was studied. The plasmid DNA analyzed by agarose gel electrophoresis revealed a heterogeneous plasmid population. Conjugal transfer appeared to be an efficient mechanism for the dissemination of resistance to gentamicin/tobramycin/kanamycin/streptomycin/chloramphenicol/cephalothin, which was the common resistance pattern in the population. Plasmids of 46, 60, ...
Effect of nutrients on culture dynamics of marine phytoplankton Eker-Develi, E; Kıdeyş, Ahmet Erkan; TUĞRUL, SÜLEYMAN (2006-01-01) The effects of nitrate, ammonium and phosphate on the abundance, chlorophyll a content (chl a), in vivo fluorescence, particulate organic carbon, nitrogen, phosphorus and cell morphology of the diatom Skeletonema costatum, the dinoflagellate Prorocentrum micans and the coccolithophore Emiliania huxleyi were investigated in the laboratory. The carbon:chlorophyll a ratio (as weight), a parameter often used in productivity estimates, differed substantially among the three species as well as at different nutrie...
