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

Checklist of Turkish Raphidioptera on the basis of distribution pattern and biogeographical analysis

Savaş CANBULAT

An updated checklist of the species of Turkish Raphidioptera and further analysis concerning their zoogeographical distribution are presented in this study. The present checklist has been based on studies from the literature and includes records from extensive material that I have identified over the last few years. The Turkish Raphidioptera presently comprises 40 species in 8 genera and 2 families. There are 38 species of Raphidiidae, while there are only 2 species of Inocelliidae in Turkey. Among these species, 19 species are recorded as endemic and the endemism rate is 47.5%. Distributions ...More

The usability of Juniperus virginiana L. as a biomonitor of heavy metal pollution in Bishkek City, Kyrgyzstan

Zeki SEVEROĞLU | İlhan DOĞAN | Gülbübü KURMANBEKOVA

Uncontrolled and unplanned urbanization and industrialization due to increase of population and rapid industrial development have created severe environmental problems in Kyrgyzstan during the last few decades. In this study, Juniperus virginiana, a dioecious species, was employed in order to make assessment of the heavy metal pollution rate in the area and of the heavy metal pollution impact on the mineral nutrient status of the plant. For this study, leaf (washed and unwashed) and bark samples of J. virginiana, and its co-located soil samples were collected from eight different stations, all ...More

Investigation of changes in chemical composition and rheological properties of Kyrgyz rice cultivars (Ozgon rice) depending on long-term stack-storage after harvesting

Camilya SMANALİYEVA | Kalıypa SALİYEVA | Bakıt BORKOYEV

The present work investigated the effect of long-term stack-storage after harvesting on selected chemical and rheological properties of Kyrgyz rice cultivars, Ozgon. The performance indicators of in stack-stored Ozgon rice samples after 4, 6, and 12 days was grain size, grain weight, color, moisture, total starch, amylose, protein, fat and ash contents, and mineral composition as well as the rheological properties of rice flour dough. The change of stored rice is caused by the organic modification of the starch structure, decreasing of moisture as well as proteolysis of proteins in the endospe ...More

Phosphorus-nitrogen compounds: part 30. Syntheses and structural investigations, antimicrobial and cytotoxic activities and DNA interactions of vanillinato-substituted NN or NO spirocyclic monoferrocenyl cyclotriphosphazenes

Ali Osman SOLAK

The gradual Cl replacement reactions of NN (1–3) or NO spirocyclic monoferrocenyl cyclotriphosphazenes (4 and 5) with the potassium salt of 4-hydroxy-3-methoxybenzaldehyde (potassium vanillinate) resulted in the mono (1a–5a), geminal (gem-1b–5b), non-geminal (cis-5b and trans -1b–4b), tri (1c, 3c–5c) and tetra-vanillinato-substituted phosphazenes (1d–5d). All the phosphazene derivatives have stereogenic P-center(s), except tetra-substituted ones. The vanillinatophosphazenes have reversible voltammograms with one-electron anodic and cathodic peaks which are attributed to ferrocenyl redox probe. ...More

Effect of different storage temperatures on the stability of bovine viral diarrhea virus RNA in blood samples

Orhan YAPICI

The present study was conducted to determine stability of Bovine viral diarrhea virus (BVDV) RNA stored at different temperatures. A total of 6 blood samples obtained from a private cattle farm, which were found to be antigen positive (Ag+) by direct ELISA method, were used in this study. BVDV Ag+ samples were stored separately at 4, 21 and 37oC for 1 month. The samples were analyzed on the 0, 1st, 2nd, 3rd and 4th weeks by ELISA for the presence of BVDV Ag and by RT-PCR for the presence of BVDV RNA. Stability of BVDV RNA was calculated using maximum concentration (Cmax) and area under the cur ...More

Fecal Ciliate Composition of Domestic Horses (Equus caballus Linnaeus, 1758) Living in Kyrgyzstan

Nurbek ALDAYAROV

Species composition and distribution of intestinal ciliates were investigated in the feces from 15 domestic horses living in Bishkek, Kyrgyzstan. Twenty-three species belonging to 14 genera were identified. This is the first study on intestinal ciliates in domestic horses living in Kyrgyzstan. The mean number of ciliates was 14.1 +/- 6.8 x 10(4) cells ml(-1) of feces and the mean number of ciliate species per host was 6.0 +/- 3.2. No endemic or new species were detected. Blepharocorys was the major genus as these ciliates were detected in high proportions. In contrast Holophryoides, Allantosom ...More

The Distribution of PAS-Positive Uterine Natural Killer (uNK) Cells in the Decidua Basalis of Pregnant Mice = Gebe Farelerde Desidua Bazalis Dokusundaki PAS-Pozitif Uterus Doğal Katil Hücrelerinin Dağılımı

Nariste KADIRALİYEVA

Bu çalışma, gebeliğin farklı dönemlerindeki fare desidua bazalis dokusunda periyodik-asit Schiff (PAS)-pozitif granüllere sahip uterus doğal katil (uNK) hücrelerinin dağılımının belirlenmesi amacıyla yapıldı. Bu amaçla, 12-14 haftalık fareler, gebe olmayan-kontrol grubu ile gebeliğin birinci, ikinci ve üçüncü haftalarının ortasına karşılık gelecek şekilde erken, orta ve geç gebelik dönemi (sırasıyla gebeliğin 3, 10. ve 17. günleri) olmak üzere 4 gruba ayrıldılar (n= 6). Plasentasyonun ilerlemesiyle birlikte metriyal bölge (MLAp; mesometrial lymphoid aggregate of pregnancy), desidua bazalis, ba ...More

The effect of drinking water and isotonic sports drinks in elite wrestlers

Serdar GERİ

The purpose of this study was to investigate the effects of sports drinks (isotonic) and water consumptions of the elite wrestlers during the exercise. Eighteen-trained elite wrestlers participated in this study. The subjects were divided into two groups according to their body-weight and were also given either water or isotonic sports drink. Water and sports drinks get rid of the dehydration during the trainings (P>0.05). Blood samples were taken before and after the exercises,and were analyzed for Sodium (Na), Potassium (K) and Chlorine (Cl). Body temperatures of subjects were measured as ºC ...More
