    The study aims to analyze, in terms of content and process, the math talks between the mother and child during the shared book reading of the illustrated storybooks with math contents. The study group under the research is comprised of nine pairs of mother and child. The process of the study 18 videos which were recorded when two storybooks with math contents were read by the mothers. In the data collection process, each pair of mother and child together read two storybooks given to them in their home environment, and the entire process was video-recorded. Subsequently, interviews were held with mothers for identifying their views about supporting their children’s math skills. It was shown that the content of mother-child math talks in the home environment was mostly about the learning area of numbers and counting skills. It was a remarkable result that math concepts such as sorting/ranking and properties/features of objects were not in the contents of mother-child math talks. The results from interviews with mothers, it was inferred that the mothers viewed themselves as inadequate for talking to their children about math concepts, and performed the math talks mostly on the basic skills such as counting the numbers

    Objective: To determine the serum concentrations of aflatoxin B-1 (AFB(1)), aflatoxin B-2 (AFB(2)), aflatoxin G(1) (AFG(1)) and aflatoxin G(2) (AFG(2)) in the healthy adult population living in both the Black Sea and Mediterranean regions of Turkey and to investigate the regional, seasonal and gender variability in aflatoxins (AF) exposure in these regions. Design: Serum AFB(1), AFB(2), AFG(1) and AFG(2) concentrations were analysed by HPLC. Settings: In total, four hundred and eighty-four serum samples were analysed. Subjects: Four hundred and eighty-four healthy adult volunteers living in rural areas of the Black Sea and Mediterranean regions of Turkey were studied. Results: The mean serum concentration of total AF in the Black Sea region was 1.33 ppb (min-max 0.15-3.38 ppb) and 0.90 ppb (min-max 0.18-2.48 ppb) for summer and winter, respectively. In the Mediterranean region, the mean serum concentration of total AF was determined as 0.55 ppb (range 0.04-1.72 ppb) for summer and 0? 45 ppb (range 0.12-1.43 ppb) for winter. The total AF concentrations in serum samples were statistically higher in summer compared with winter for the two regions. The differences between the regions were statistically significant concerning all samples, with higher total AF concentrations in the Black Sea region. Conclusions: The overall results suggest that the Turkish population living in these two regions is continuously exposed to AF, particularly in the summer, and that mycotoxin contamination in food should be monitored routinely for food safety and human health

    The susceptibility of 49 Mycobacterium tuberculosis clinical isolates to isoniazid (INH) and rifampisin (RIF) (28 multi-drug resistant-tuberculosis samples) was determined by a nitrate reductase assay (NRA) on blood agar. Agreement between the NRA and other testing methods was found to be 93.8% for both INH and RIF. The sensitivity, specificity, positive predictive value and negative predictive value for INH were 92.8%, 94.2%, 86.6% and 97%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value for RIF were 90.4%, 96.4%, 95% and 93.1%. In conclusion, we show here that blood agar can be used effectively for the NRA test

    In vitro effect of tigecycline against Mycobacterium tuberculosis and a review of the available drugs for tuberculosis

    The study aimed to investigate the effectiveness of a novel antibiotic drug tigecycline on clinical isolates of Mycobacterium tuberculosis and, reviewing defined anti-tuberculosis effects of available agents. Minimal inhibitory concentration (MIC) of tigecycline for 50 M. tuberculosis including multidrug-resistant (MDR) clinical isolates (20 MDR isolates) was determined by broth microdilution method in the study. Tigecycline MIC values were ranging between 8 and 64 mu g/ml. However, there is not any defined break point for M. tuberculosis resistance. In conclusion, it seems that the in vitro effectiveness of tigecycline to M. tuberculosis is not good but further in vivo studies are needed
