We used the anaphase-telophase chromosome aberration and comet (Single Cell Gel Electrophoresis, SCGE) assays to evaluate the genotoxic effects of copper sulphate (CS) and cobalt chloride (CC) chemicals prepared in two concentrations (EC(50), 2xEC(50)), using methyl methanesulfonate (MMS) as a positive control and untreated cells as a negative control. In(More)
This report deals with micropropagation of the critically endangered and endemic Turkish shrub, Thermopsis turcica using callus, root and cotyledonary explants. Callus cultures were initiated from root and cotyledon explants on MS medium supplemented with 0.5–20 µM NAA or 2,4-D. The root explants were found to be better in terms of quick responding and(More)
Plants with antidiabetic activities provide important sources for the development of new drugs in the treatment of diabetes mellitus. In the present study, we investigated possible antihyperglycemic and antioxidative activities of the aerial part of the Matricaria chamomilla L. ethanolic extract (MCE) in streptozotocin (STZ; 70 mg/kg, i.p.)-induced diabetic(More)
The therapeutic effects of melatonin or vitamin E plus Se (vE + Se) on the restrain of the heroin withdrawal-induced oxidative stress were studied. For this, rats were divided into ten groups. The rats were injected by fixed or variable doses of heroin for 16 consecutive days, and naloxone was given 1 h after the last heroin injection. One hour after(More)
The incidence of neural tube defects is higher in Turkey compared to that of developed countries. To prevent congenital malformations, understanding of the current status is necessary, which should be followed by public-based activities. We examined the incidence rate of neural tube defects (NTDs) in Afyonkarahisar. According to the records of the(More)
In this study, it was aimed to determine organochlorine pesticides (OCPs) in three types of milk (cow's, buffalo's, and sheep's milk) produced in Afyonkarahisar province of Turkey. The results indicated that these milk specimens were found to be contaminated by 21 different pesticides. Sixteen OCP residues were detected in sheep's milk and it was followed(More)
Assessment of genotoxins-induced DNA damage and mutations at molecular level is important in eco-genotoxicology. In this research, RAPD was used to detect DNA damage in the roots and leaves of bean (Phaseolus vulgaris L.) seedlings exposed to toxic chemicals of Hg, B, Cr and Zn (HgCl(2), H(3)BO(3), K(2)Cr(2)O(7) and ZnSO(4)7H(2)O) at concentrations of 150(More)
In this study, δ-aminolevulinic acid dehydratase (ALAD) from Streptomyces yokosukanensis ATCC 25520, producer of an unusual purine riboside antibiotic called nebularine, was purified and characterized. Purification procedures were involved with ammonium sulphate precipitation and gel filtration techniques by use of Sephacryl S-200. After gel filtration a(More)
Water, dried material, pH, protein, ash, lipid, cellulose, non-cellulose carbohydrate, Ca, Cu, Fe, K, Mg, Na, P, Zn contents of 15 edible and naturally growing mushrooms from Western Black Sea Region of Turkey have been analysed. Both organic and inorganic elements were analysed statistically by Pearson correlation analyse and some statistically meaningful(More)
Heroin use, withdrawal syndrome, and heroin-related deaths are still the most serious public health problems. Antioxidants and bio-elements are essential for metabolism in living organisms. To our knowledge, there are no data about the effect of antioxidant therapy on the levels of bio-elements and antioxidant enzymes in the naloxone (NX)-induced heroin(More)
