The effect of yeast culture products (Rumisacc and Intertotal) on fattening performance, some blood and rumen fluid parameters in male kids

The aim of this study was to evaluate the effects of live yeast culture and the combination of live yeast culture with vitamin-mineral supplementation as a feed additive on fattening performance, some blood and rumen fluid parameters in male kids. Totally 18 male Saanen goat kids were divided in to one control and two treatment groups each containing 6 kids. Rations of groups were formulated as isonitrogenic and isocaloric. Live yeast culture (YC) and the combination product (YVM) (RumiSacc® and Intetotal® respectively,by Integro Food Industry and Trade Co., Istanbul, Turkey; Live yeast cell 344 x 1010 cfu per gram) was included in the concentrates at 0 (C), 1% (YC) and 1% (YVM) on feed basis, respectively. Feeding schedule was established with only concentrate. Feed was given ad libitum and roughage was not given. Dietary yeast culture at the level of 1% increased final live weight (+4.7% regarding control group). All investigated fattening performance with rumen fluid and blood parameters were not statistically affected with the supplements. It is concluded that live yeast culture and its vitamin-mineral combination did not have adverse affect in male kids fed without roughage

The effects of the addition of baker's yeast on the functional properties and quality of tarhana, a traditional fermented food

As a fermented product, tarhana is the dry form of yogurt-cereal mixture and represents an important part of the diets of many people in different countries including Turkey. In the present study, the effects of the addition of baker's yeast on the quality and functional properties of tarhana were investigated. Tarhana was produced under laboratory conditions (uncontrolled and controlled conditions) using two formulas. Some physicochemical, functional, and sensory properties of the samples were analysed. An increase was found in the acidity value of all samples during the fermentation period. The addition of baker's yeast affected the functional properties (water absorption capacity, foaming capacity, foaming stability, emulsifying activity) of the samples (P < 0.05). The tarhana samples produced by the addition of yeast and under controlled conditions had shorter fermentation times and better sensory properties. This research suggests that the addition of baker's yeast and the employment of controlled conditions can be recommended in the production of the commercial type of tarhana

Cytokine gene polymorphism frequencies in Turkish population living in Marmara region

Objectives Sequence variants in cytokine genes are related to affect cytokine gene levels. In this study, it was aimed to examine eight single nucleotide polymorphisms (SNPs) in five cytokine genes (TNF-alpha, INF-gamma, IL-6, IL10, TGF-beta) for the Turkish population living in Marmara region and to reveal the genetic distance between the study group and other populations. Methods In this study, three-hundred unrelated healthy individuals were involved and all genotyping were performed by using sequence-specific primers PCR (PCR-SSP) method. The SNP data were analyzed for Hardy Weinberg equilibrium fit by calculating expected genotype frequencies and comparing them to the observed values using Arlequin software version 3.1. The genetic distances between the study group and other populations were calculated and a neighbor-joining tree was constructed by PHYLIP. Results The observed genotypes of TNF-alpha (-308), IFN-gamma (+874), TGF-beta (codon 10), and TGF-beta (codon 25) of the subjects were found to be similar with other populations investigated in this study. However, there is a significant frequency difference for IL-6 and IL-10 genotypes between populations. Conclusions The current population study provided more reference values for these polymorphisms and generated a control group to be used in further association studies especially for transplantation, GVHD, autoimmune and malign disease

TEKSTİL ATIK SUYUNDA HRP-CLEA İLE HİDROJEN PEROKSİDİN GİDERİLMESİ İÇİN ÖLÇEK BÜYÜTME TASARIMININ MODELLENMESİ VE SİMÜLASYONU

Hydrogen peroxide is a strong oxidant chemical used asa bleach in the textile industry and it is important to remove it from water before being released to the environment. The oxidizing substrate of peroxidase (HRP) enzyme is hydrogen peroxide. In this study, cross-linked aggregates (CLEA) of HRP enzyme were used to remove hydrogen peroxide and glutaraldehyde (GA) was used as a crosslinking agent.When the kinetic constants of the free peroxidase enzyme were calculated, saturation constant was 0,06965 mmol H2O2/L and maximum specific rate constant was found as 0.0232mmol H2O2/L.sec. Average saturation constant, Kmof HRP-CLEA was found as 0,00625 mmol H2O2/L, and average maximum specific rate constant value, Vm, was calculated as 0.0699x10-3 mmol H2O2/L.sec in wastewater without dye. More then 90 % H2O2removal was achieved in 15 minutes with HRP-CLEA. The removal of the wastewater containing H2O2(0.02M) was completed in five minutes.In the scale-up approach, the data was evaluated using the Euler solution algorithm and the H2O2removal in the efficiency factor range where the kinetic constants change was calculated. Assuming the reaction rate changes linearly, the activity variations that will occur during scaling up with the enzyme in aggregate form were determined in the range of 125% -50%, and the industrial-scale design was modelled by taking into account the activity factors. In scaling up, concentrations that will occur in the increased reaction volume have been simulated. The results obtained showed that HRP-CLEAs are more advantageous than free enzyme in terms of time and cost

An Investigation of Preschool Children’s Usage Level of Concepts Related to Position-in-Space

Çocuklar için mekânda konum kavramlarının kazanımı erken yıllarda başlayarak, okul öncesi dönemde eğitimin etkisi ile hızlı bir ilerleme kaydetmektedir. Bu çalışmada, okul öncesi eğitime devam eden 83 çocuğun mekânda konum kavramlarını kullanımları incelenmek için örnek bir resim kullanılmıştır. Çalışmaya dört farklı ilde eğitim gören 43 kız ve 40 erkek çocuk katılmış olup, resimde görülen dokuz farklı kişinin yerleri tarif edilerek, alınan cevaplar kaydedilip, daha sonra araştırmacıların analizleri sonucu, her bir kişi için dört farklı (mekanda konum ifadeleri kullanarak tarif edenler, mekanda konum ifadelerini kullanmadan doğru tarif edenler, mekanda konum ifadelerini kullanarak yanlış tarif edenler ve mekanda konum ifadelerini kullanmadan yanlış tarif edenler) başlık ortaya çıkarak, bu başlıklara göre değerlendirilmiştir. Araştırma sonucunda, çocuklar mekânda konum ifadelerini kullanarak doğru tarif edenler olduğu kadar mekânda konum ifadelerini kullanmadan doğru tarif eden cevaplar da olduğu görülerek, genel olarak çocukların doğru cevabı bildikleri fakat kavramsal gelişimlerin yeterli olmadığı görülmüştür.The acquisition of spatial location concepts for children starts in the early years and has significant progress with the impact of education in the early years. In this study, a sample picture was used to examine the usage of the concept of location in space for 83 children attending preschool education. 43 girls and 40 boys attending preschools in four different cities participated in this research. In the sample picture, the locations of nine different people were described, and the answers were recorded. Then, four different categories (those who described using location concepts, those who described correctly without using location concepts, those who failed to describe using location concepts, and those who failed to describe without using location concepts) were determined for each person as a result of the researchers’ analysis. Children’s responses for each person were evaluated according to these categories. As a result of the research, some answers describe the children correctly using location concepts as well as those that describe them correctly without using location expressions. Thus children generally know the correct answer, but their conceptual development may not be sufficient to describe using conceptual words
