Arsenic Removal by Electrocoagulation

Mehmet KOBYA

Because of the toxic impacts on human health, the arsenic (As) limit value in drinking water was decreased from 50 to 10 μg l −1 by the relevant authorities (WHO 1993; US EPA 2001). In this case, the problem of As pollution in natural water resources used for drinking water has grown even more and turned into a global crisis. According to reports in many parts of the world, over about 230 million people appear to be affected by high arsenic concentrations in groundwater. In this case, it turned out that there was a great need for cost-effective and environmentally friendly technologies from dr ...More

Carbon Nanotube Supported CdM(S, Se)/CdTe Anode Catalysts for Electrooxidation of Glucose in Alkaline Media

Hilal DEMİR KIVRAK | Nahit AKTAŞ

The sequential sodium borohydride (SBH, NaBH4) reduction method was utilized to prepare the 0.1 CdSe/CNT, 0.1 CdS/CNT, 0.1 (CdS-CNT)/CdTe, and 0.1 (CdSe-CNT)/CdTe catalysts. The XRD, SEM-EDS, TEM, and XPS analyses were used to characterize the catalysts. The electrochemical measurements were examined by cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) analyses for glucose electrooxidation. The characterization analyses revealed that the desired structure was formed on the support material. The electrochemical analysis results indicated that the ...More

The relationship between Th1/Th2 cytokine polarization and milk composition in the postnatal period in Kyrgyz mares and foals

Fatih Ramazan İSTANBULLUGİL | Ali RIŞVANLI | Ruslan SALIKOV | Nariste KADIRALİYEVA | Ayday CUNUŞOVA

Immune compatibility between mare and foal is one of the important topics of reproductive immunology. At this point, although there are many studies on antibodies, there are not many publications on the relationship between the cytokine levels of mare, foal and milk and the effects of milk composition on this relationship. Here we investigate the relationship between Th1/Th2 cytokine balance and milk composition in Kyrgyz mares and foals. Samples were taken soon after the foal was born and on days 5, 10 and 20 after birth. Th1 (IFN-γ, IL-2, TNF-α) and Th2 (IL-4, IL-5, IL-10) cytokine levels in ...More

Fabrication of molecularly imprinted cotton fibers for quantification of streptomycin in honey samples

Nahit AKTAŞ

Streptomycin is a type of aminoglycoside used in treatment of several infections and with serious side effects in humans and animals, such as ototoxicity and nephrotoxicity. In the present study, we focused on the preparation of streptomycin-imprinted cotton fiber for rapid, sensitive and selective quantification of streptomycin in honey samples. The imprinted cotton fibers were characterized by attenuated total reflectance-Fourier transform spectroscopy, scanning electron microscopy, and x-ray photoelectron spectroscopy. In addition, the imprinted cotton fibers showed high adsorption capacity ...More

Damla ARSLAN ACARÖZ

BackgroundThis study investigates the effects of cryopreservation and supplementation of Azeri water buffalo's semen with proline (Lp) and fulvic acid (FA). ObjectivesTherefore, this study aimed to assess motility parameters, sperm viability, oxidative stress parameters, and DNA damage to detect the optimum concentrations of Lp and FA for buffalo semen cryopreservation. MethodsThirty semen samples of three buffalo bulls were diluted in Tris-egg yolk extender and divided into 12 equal groups including control (C), Lp-10, Lp-20, Lp-40, Lp-60, Lp-80 (containing 10, 20, 40, 60, 80 mM L-proline, re ...More

Synthesis, Characterization, and Investigation of Coating Properties of Carboxymethyl Acorn Starch (CMAS)

Nurzat ŞAYKİYEVA | Mirlan MOLDOBAYEV | Kubat KEMELOV | Canıl İSKAKOVA | Mustafa DOLAZ

Kyrgyzstan is a landlocked country in Central Asia, famous for its crystal-clear lakes, majestic Tien Shan Mountains that bisect the territory of Turkistan, and magnificent natural beauty. This study aims to evaluate the fruit (acorns) of the oak trees (Quercus robur L.) grown in Bishkek, the capital city of Kyrgyzstan. For this purpose, carboxymethyl acorn starch (CMAS), which is not synthesized in literature, is first synthesized by isolating acorn starch (AS) from the acorns. The structures of CMASs are characterized by H-1(C-13)-NMR, FT-IR, XRD, and SEM techniques. The viscosities of the s ...More

p(thyme oil) and p(clove oil) organo-particles with biocompatible, anticancer, antioxidant, and antibacterial properties against Capan-1 and L-929 cells

Nahit AKTAŞ

The synthesis of p(ClO) and p(TO) organo-particles from clove oil and thyme oil is the first in the literature. The particles were tested against the L-929 cell line for cell viability/cytotoxicity. The anticancer activity was studied against the Capan-1 pancreatic cancer cell line. p(ClO) and p(TO) organo-particles were featured by thermogravimetry (TGA), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), particle size (DLS), and particle charge (zeta potential, Zeta) analyses. Antioxidant, biocompatible, antimicrobial, and in vitro cytotoxicity specialties w ...More

Genetic analysis of PALB2 gene WD40 domain in canine mammary tumour patients

Ali RIŞVANLI

Background: DNA repair mechanisms are essential for tumorigenesis and disruption of HR mechanism is an important predisposing factor of human breast cancers (BC). PALB2 is an important part of the HR. There are similarities between canine mammary tumours (CMT) and BCs. As its human counterpart, PALB2 mutations could be a predisposing factor of CMT. Objectives: In this study, we aimed to investigate the impacts of PALB2 variants on tumorigenesis and canine mammary tumor (CMT) malignancy. Methods: We performed Sanger sequencing to detect germline mutations in the WD40 domain of the canine PALB2 ...More

Fabrication of an Electrochemical E. coli Biosensor in Biowells Using Bimetallic Nanoparticle-Labelled Antibodies

Ali Osman SOLAK

An electrochemical biosensor was developed for the determination of Escherichia coli (E. coli) in water. For this purpose, silver-gold core-shell (Ag@Au) bioconjugates and anti-E. coli modified PS-microwells were designed in a sandwich-type format in order to obtain higher sensitivity and selectivity. Ag@Au bimetallic nanoparticles were synthesized by co-reduction method. The core-shell formation was analyzed by using UV-Vis spectroscopy and transmission electron microscopy. Biotin labeled anti-E. coli antibodies were coupled with Ag@Au nanoparticles to form bioconjugates. The electrochemical ...More

Ali Osman SOLAK

In this study, 4-thiophenol modified glassy carbon electrode was prepared by the reduction of 4-diazothiophenol tetrafluoroborate salt. Silver nanoparticles were attached to the thiophenol modified surface to prepare a thiophenol-silver nanoparticle composite film. 4-Aminothiopenol molecules were deposited by self-assembling technique to form multi-layered nanofilms of TP/SNP/PhNH2 on glassy carbon substrate. These surfaces were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, X-ray photoelectron spectroscopy, reflectance-absorption infrared spectroscopy, and ellips ...More

Detection of Escherichia coli O157:H7 using immunomagnetic separation and mPCR in Turkish foods of animal origin

Zafer GÖNÜLALAN

The present study was conducted to investigate the presence of Escherichia coli O157:H7 in food samples of animal origin and to detect its virulence genes by immunomagnetic separation technique and multiplex PCR (mPCR). A total of 500 samples (consisting of diced meat, minced meat, burger, raw cow's milk and raw cow's milk cheese) were analysed. Escherichia coli O157:H7 was detected in 5 (1%) of 500 analysed samples including two diced meat, one minced meat and two raw-milk cheese. None of the burger samples tested contained E. coli O157:H7. Three isolates obtained from minced and diced meat w ...More
