Item Zinc tolerance test patterns in normal children and in moderate and severe zinc deficiency states(Springer India, 1996) Oksel F.; Köksyo H.; Taneli B.Twenty-six normal, 38 moderately and 14 severely zinc-deficient children, aged 2-12 years, were examined by clinical and laboratory approaches. After fasting-blood sampling, 120 mg zinc sulphate (25 mg elemental zinc) were administered orally to each group of children, to obtain zinc tolerance curve patterns. Sampling proceeded to the 2nd and 4th hours of the loading test period. Plasma zinc was assessed on an atomic absorption spectrophotometer. In normal children, at the 2nd hour of loading, a significant (p < .001) elevation (1.764 ± 0.133 mg/l) in the mean (±SEM) plasma zinc level was noted; also at the 4th hour a significant (p < .001) decrease (1.506 ± 0.123 mg/l) in the mean plasma zinc level was shown. The mean plasma zinc level at the 4th hour was found higher than the mean fasting plasma zinc level (1.054 ± 0.061 mg/l), but lower than the mean level found at the 2nd hour. In moderately zinc-deficient children, tle rise in the 2nd hour and the fall in the 4th hour in the plasma zinc level were highly significant (p < .001 and p < .001, respectively) in relation to fasting blood level. However, in severely zinc deficient children, the intensity of the increase (0.746 ± 0.147 mg/l) in plasma zinc level at the 2nd hour was of lesser significance (p < .006) and the fall (0.424 ± 0.061) mg/l) at the 4th hour was not significant. Therefore, in children with normal plasma zinc levels, an increase of more than 0.50 mg/l was seen at the 2nd hour of loading. This rise was seen to persist at the 4th hour. However, in children with moderate zinc deficiency, although again an increase of 0.50 mg/l was seen at the 2nd hour this increase did not persist at the 4th hour; and the 4th-hour value showed a significant decrease in relation to the 2nd hour value. Whereas, in children with severe zinc deficiency the rise of plasma level at the 2nd hour was less than 0.5 mg/l and the fall at the 4th hour was to such a level which was not significant in relation to fasting zinc level. This could be due to enhanced uptake of zinc off the circulation by the depleted tissues in severe zinc deficiency.Item Optimization of compositional and structural properties in probiotic sausage production(Springer India, 2016) Bağdatli A.; Kundakci A.In this study, the effects of different fat levels and different particle sizes on compositional and structural characteristics of probiotic fermented sausage were investigated. In order to obtain probiotic character, Lactobacillus casei CRL431 was added. The physicochemical, microbiological and sensory analysis were done. The effect of fat level x mincer hole diameter interaction on hardness values were statistically significant (p < 0.005). At the end of the fermentation-ripening period, L.casei CRL-431 count has reached to sufficient microbial count (106 cfu/g of probiotic bacteria) to demonstrate the character of probiotic food. A significant positive correlation was found between L.casei CRL431 count and surface appearance, texture and overall acceptability scores (r = 0.60, 0.52, 0.53). The values of TBARS number of probiotic sucuk samples increased during fermentation-ripening. A significant correlation between taste-aroma scores and fat level was detected (r = −0.61,p = 0.0008). Consiquently, the best sensorial quality was determined in L3 samples and the worst sensorial quality was determined in H8 samples. © 2015, Association of Food Scientists & Technologists (India).Item Do prion protein gene polymorphisms induce apoptosis in non-mammals?(Springer India, 2016) Birkan T.; Şahin M.; Öztel Z.; Balcan E.Genetic variations such as single nucleotide polymorphisms (SNPs) in prion protein coding gene, Prnp, greatly affect susceptibility to prion diseases in mammals. Here, the coding region of Prnp was screened for polymorphisms in red-eared turtle, Trachemys scripta. Four polymorphisms, L203V, N205I, V225A and M237V, were common in 15 out of 30 turtles; in one sample, three SNPs, L203V, N205I and M237V, and in the remaining 14 samples, only L203V and N205I polymorphisms, were investigated. Besides, C658T, C664T, C670A and C823A SNPs were silent mutations. To elucidate the relationship between the SNPs and apoptosis, TUNEL assays and active caspase-3 immunodetection techniques in brain sections of the polymorphic samples were performed. The results revealed that TUNEL-positive cells and active caspase-3-positive cells in the turtles with four polymorphisms were significantly increased compared with those of the turtles with two polymorphisms (P<0.01 and P<0.05, respectively). In conclusion, this study provides preliminary information about the possible relationship between SNPs within the Prnp locus and apoptosis in a non-mammalian species, Trachemys scripta, in which prion disease has never been reported. © 2016, Indian Academy of Sciences.Item Digital Fibrations(Springer India, 2017) Ege O.; Karaca I.In this paper, digital fibrations were introduced. Theorems related to digital fibrations were proved. Homology properties of digital fibrations with counter examples were studied and an application for digital fibrations was also described. © 2016, The National Academy of Sciences, India.Item A New Version Darboux Vector and Characterization Some Special Curves According to Type-2 Bishop Frame in R3(Springer India, 2017) Yılmaz S.; Savcı Ü.Z.In this paper, we introduce a new Darboux vector and Darboux helix a curve according to type-2 Bishop frame in R3. We defined a new Darboux vector in term of type-2 Bishop frame in R3. We introduce a new spherical indicatrix, Darboux helix and constant precession of the curve type-2 Bishop in Euclidean 3-space. We give new characterization between Darboux helix and general helix. Apart from, the following characterization is given. The curve α∈ R3 is an inclined curve if and only if the arc length sω0 of the Darboux spherical indicatrix of the α is constant. Finally we illustrate one example of our main results. © 2017, The National Academy of Sciences, India.
