Utjecaj dodatka praha sluzi chia sjemenki (Salvia hispanica L.) na neka fizikalno-kemijska i reološka svojstva ayrana

In this study, chia seed mucilage powder (MP) was added into ayran drinks at different ratios (0.05, 0.10 and 0.15%, w/v), and its effect on physicochemical, rheological, microbiological and sensory properties of ayran drinks was determined during 10 days of storage at 4±1 °C. MP addition did not influence their major chemical composition significantly (p>0.05). Increasing MP ratio in drinks decreased the colour L* values of drinks while increasing their colour a* and b* values. Addition of 0.05, 0.10 and 0.15% MP reduced serum separation values of drinks by 25, 67 and 83%, respectively. The apparent viscosity value of control samples was 103.20 cP and increased to 134.25, 185.35 and 223.38 cP in ayran drinks with 0.05, 0.10 and 0.15% MP, respectively. The obtained results indicated that chia seed MP up to 0.05% can be used in ayran drink production to reduce serum separation and improve viscosity without any adverse effect on sensory liking scores.U ovom istraživanju, prah sluzi chia sjemenki (MP) dodan je u ayran napitke u različitim omjerima (0,05, 0,10 i 0,15 %, w/v) te je ispitivan njegov učinak na fizikalno-kemijska, reološka, mikrobiološka i senzorska svojstva ayran napitaka tijekom 10 dana skladištenja na 4±1 °C. Dodatak MP nije značajno utjecao na njihov glavni kemijski sastav (p>0,05). Povećanje omjera MP u pićima smanjilo je L* vrijednosti boje pića dok je povećalo njihove a* i b* vrijednosti boje. Dodatak 0,05, 0,10 i 0,15 % MP smanjio je vrijednosti sinereze napitaka za 25, 67 odnosno 83 %. Prividna viskoznost kontrolnih uzoraka bila je 103,20 cP i porasla je na 134,25, 185,35 i 223,38 cP u ayran napicima s 0,05, 0,10 i 0,15 % MP. Rezultati su pokazali da se MP chia sjemenki do 0,05 % može koristiti u proizvodnji ayrana, kako bi se smanjila sinereza i poboljšala viskoznost bez ikakvih negativnih učinaka na senzorska svojstva

The effect of educational technologies and material supported science and technology teaching on the problem solving skills of 5(th) grade primary school student

World Conference on Educational Sciences -- FEB 04-07, 2009 -- Nicosia, CYPRUSWOS: 000275580400110The aim of this research is todetermine the effect of educational Technologies and material supported science and technology teaching on the problem solving skills of 5th grade primary school students fort his reason the software made for teaching the subjects of "The World, Sun and Moon" unit of the science and Technology lesson was prepared with the Macromedia Flash 8 program. The Buca Primary School in Buca, zmir is the scope of this quasi experimental design study which is suitable fort he "Pre-test, Post-test control group" model. The participants are 80 studenrs from the 5-C and 5-F classes of Buca Primary School of the 2006-2007 academic year. For this research, as the data collection device, researchers used "The Problem Solving Skills Scale" developed for Level I students. The six sub-dimensional Scale comprising 38 articles has a 82 cronbach Alfa reliability coefficient. In the analysis of the research data, arithmetic mean, standart deviation was used t-test was used to compare the pre-test, post-test results of the two groups. As a result of this research, it has been Seben taht the applied program has a positive influence on the problem solving skills perception of students. (C) 2009 Elsevier Ltd. All rights reserve

Effect of chia (Salvia hispanica L.) seed mucilage powder on some physicochemical and rheological properties of ayran drinks

In this study, chia seed mucilage powder (MP) was added into ayran drinks at different ratios (0.05, 0.10 and 0.15%, w/v), and its effect on physicochemical, rheological, microbiological and sensory properties of ayran drinks was determined during 10 days of storage at 4±1 °C.

Effects of environmental factors and storage conditions on the performance of Olyset(A (R)) Plus against sand flies in WHO cone bioassays

WOS: 000374573000008PubMed ID: 27076511Leishmaniasis, visceral and cutaneous, is seen in Turkey and has both public and veterinary importance. So far, four Leishmania species and their vectors have been detected in Turkey. Vector control is essential in endemic areas and several personal protection methods are available including long-lasting insecticidal nets (LLINs). In this study, we aimed to measure the effects of usage and storage conditions on LLINs in a village-scale study. Olyset(A (R)) Plus bed nets were set up in different climatic conditions (rain, exposed to sunlight and humidity) and collected after 6 months. The effectiveness of bed nets were tested by WHO's cone test method using wild-caught sand flies. Bed nets, which were placed directly exposed to sunlight (A1, A2) showed lower (17.2%) knock down effect compared to bed nets placed indoors (A3, B1). Twenty-four hour mortality was 100% for the five study groups (A2, A3, B1, C1, C2) whereas group A1 was found to have a lower mortality rate (44.4%). Bed nets need to avoid direct exposure to sunlight. When used and stored in appropriate conditions (cool, well-ventilated place away from sunlight) they can be used as an effective vector control tool in endemic areas.EUEuropean Union (EU) [FP7-261504 EDENext]; Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [112T270]This work was supported by the EU [grant number FP7-261504 EDENext] and is catalogued by the EDENext Steering Committee as EDENext440 (http://www.edenext.eu).

Is the MDR1 C3435T polymorphism responsible for oral mucositis in children with acute lymphoblastic leukemia?

Background and Aim: Although the functional consequences of MDR-1 polymorphisms have been the subject of numerous studies, to the best to our knowledge, associations with clinical side effects of anticancer drugs have yet to be assessed. Our aim was to clarify any role of the C3435T polymorphism of the MDR1 gene in oral mucositis and its relation with elevated reactive oxygen species (ROS) levels, in children with acute lymphoblastic leukemia (ALL). Materials and Methods: The distribution of the MDR-1 C3435T polymorphism in 47 patients with ALL was determined by RFLP and compared with that of 68 healthy controls. Results: There were no association in distribution of genotypes of MDR-1 C3435T polymorphism and the risk of ALL. Oral mucositis were detected in 78.7% (n=37) of the patients and significantly related to the MDR-1 CT genotype (p=0.042), as confirmed by logistic regression analysis. Conclusion: Our preliminary data suggest that children carrying the CT genotype are more prone to develop oral mucositis, which might mean that the heterozygous genotype leads to accumulation of more reactive oxygen species. Since a limited number of patients was investigated, further studies are needed to confirm these findings
