Evaluation of Some Redox Mediators in the Design of Reagentless Amperometric Glucose Biosensor

Ali Osman SOLAK

The influence of redox mediators (tetrathiafulvalene (TTF), tetrathiafulvalene-tetracyanoquinodimethane complex (TTF-TCNQ), phenazine methosulfate (PMS), 5,6-diamino-1,10-phenonthroline (5,6-DAP), potassium ferrocyanide (K4[Fe(CN)6]), methylene blue (MB) and toluidine blue (TB)) on the response of amperometric glucose biosensor was investigated in this research. Graphite rod electrode (GRE) modified by adsorbed mediator and glucose oxidase (GOx) cross-linked with glutaraldehyde was served as working electrode. The highest amperometric signals were observed by using TTF and TTF-TCNQ as mediator ...Более

Efficient in vitro plant regeneration from immature embryos of endemic Iris sari and I. schachtii

Ali İrfan İLBAŞ

Plant tissue culture is an efficient technique for conserving endemic plant species. A reproducible in vitro regeneration protocol was developed for the endemic Iris sari and Iris schachtii in the present study. The highest number of shoots per explant was obtained on Murashige and Skoog (MS) medium supplemented with 0.5 mg/L thidiazuron (TDZ) plus 0.5 mg/L α-naphthaleneacetic acid (NAA) and 1 mg/L TDZ plus 0.5 mg/L NAA, whereby 96.88% and 100% shoot induction with 9.55 and 11.34 shoots per explant of Iris sari and Iris schachtii were recorded, respectively. Regenerated shoots were successfull ...Более

Effects of traditional homemade koumiss on some hematological and biochemical characteristics in sedentary men exposed to exercise

İhsan KISADERE | C. BALABAN | Nariste KADIRALİYEVA

We evaluated the effects of koumiss on some hematological and biochemical characteristics of persons who exercise. Eighteen sedentary males were assigned to three equal groups: koumiss (K), koumiss + exercise (KE) and exercise alone (E). Leukocytes (WBC), differential leucocyte count, erythrocytes (RBC), hemoglobin (HGB), hematocrit (HCT), platelet (PLT), glucose, total cholesterol, triglycerides, high density lipoprotein (HDL), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were assessed In blood samples. By the end of the study, triglycerides (TG) and cholesterol levels ...Более

Electrochemical studies on graphene oxide-supported metallic and bimetallic nanoparticles for fuel cell applications

Ali Osman SOLAK

A fuel cell is an electrochemical cell that converts a source fuel into an electrical current. It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte. Fuel cells have been attracting more and more attention in recent decades due to high-energy demands, fossil fuel depletions, and environmental pollution throughout world. In this study, different sized metallic and bimetallic nanoparticles (AuNPs, Fe@AuNPs, Ag@AuNPs) were synthesized on graphene oxide sheets and their electrocatalytic activities for methanol oxidation ...Более

Protective effect of esterified glucomannan on aflatoxin-induced changes in testicular function, sperm quality, and seminal plasma biochemistry in rams

Nurcan DÖNMEZ

The aim of this study was to determine the effect of aflatoxin (AF) on spermatologic, biochemical, and testis parameters in rams, and the protective efficiency of esterified glucomannan (EG) co-administered with AF. Thirty-two Merino rams (12–14 months old) were used. The experimental design consisted of four dietary treatments. The control group was fed commercial feed. The AF group was fed with commercial feed plus 250 μg/d of total AF. The EG group received commercial feed plus 2 g/d of EG. The AF + EG group was given commercial feed plus 250 μg/d of total AF and 2 g/d of EG. There were tre ...Более

Comparison of hatchability and some egg quality characteristics in spotted and unspotted partridge (Alectoris chukar) eggs

Tamer ÇAĞLAYAN

The current research was conducted to determine the comparison of hatchability and some egg quality characteristics in spotted and unspotted partridge (Alectoris chukar) eggs. The research was carried out on 51 male and 102 female chukar partridges (Alectoris chukar) aged 50 wk, which were raised at the Research and Application Farm of the Faculty of Veterinary Medicine of Selcuk University. In total, 244 spotted and 261 unspotted eggs were used in the research. The hatching eggs were stored at 75% RH and 13°C for 14 d. Thirty spotted and 30 unspotted eggs laid on the same day were used for th ...Более

First report on seroprevalence of bluetongue, border disease and peste des petits ruminants virus infections in sheep in Kyrgyzstan

Orhan YAPICI

In this study, the presence of antibodies against Bluetongue Virus (BTV), Border Disease Virus (BDV) and Peste des Petits Ruminants virus (PPRV), were evaluated for the first time in Kyrgyzstan. A total of 655 serum samples were collected from healthy sheep (Jaydara breed) from different regions of Kyrgyzstan (144 from Issik Gol region, 208 from Narin region, 189 from Talas region and 114 from Çuy region). Commercially available competitive ELISA kits were used to detect antibodies against tested samples. Seroprevalence was found to be 36.94%, 7.32% and 35.11% against BTV, BDV and PPRV infecti ...Более

Treatment of ophidism-induced bilateral canine cataract by extracapsular lens extraction and intraocular lens implantation

Murat KİBAR

The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the temporal part of the iris, but decentration of the intraocular lens was not observed. To the best of our knowledge, this is the first report of bilateral cataract caused by ophidism and treated by surgic ...Более
