The Effect of Pneumonic Pasteurellosis on Apoptosis and Nitric Oxide Synthase in the Lungs in Calves
2020
Orhan Yavuz | Güngör Çağdaş Dinçel
Pneumonic Pasteurellosis (PP) is an infectious disease caused by Pasteurella multocida and Mannheimia haemolytica, mostly observed in cattle, sheep and calves. PP is characterized by fibrinous bronchopneumonia and pleuritis in the lungs. In this study, it was aimed to determine Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase expressions by immunohistochemical methods in the lungs suffered from PP. For this purpose, twenty lung tissues were collected from calves with PP. For the Control Group, ten lungs of calves were collected from Aksaray Slaughterhouse. After necropsies of calves were confirmed to be PP by bacteriological examinations. Then the routine histological process was performed to tissues, and stained by Hematoxylin & Eosin for histopathology, and Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase antibody staining for immunohistochemistry. The immunohistochemical findings indicated that Caspase-3, Caspase-9, inducible nitric oxide synthase and neuronal nitric oxide synthase positive reactions were seen in alveolar, bronchial and bronchiolar epithelia, and desquamated inflammatory cells in the lumens. In addition, the peripheral neural extensions were immunopositive for neuronal nitric oxide synthase and vascular endothelial cell were positive for inducible nitric oxide synthase. The findings can contribute to a better understanding of expressions of molecules such as Caspase and nitric oxide synthase. These results show that apoptosis and nitric oxide synthase expressions have triggered by airway epithelia and inflammatory cells in the lungs with Pneumonic Pasteurellosis in calves.

This study aimed to evaluate the effect of compost from chicken manure, NPK fertilizer and the mixture of both fertilizers on agronomic parameters of four varieties of cassava (Yacé, Bonoua, Six mois and Alleda agba) in Côte d’Ivoire. The field experiment was carried out under a randomized complete block design with three replicates on a ferralitic soil during two season-cycles. The results showed that the different fertilizers stimulated plants growth and tuberous roots production. The highest number of stems (3) and leaves (66) was obtained with the mixture of NPK and compost applied on the variety “Bonoua”. All varieties that received the compost mixed with NPK produced more leaves with a dominance of the Bonoua variety (65.57). The highest number of tuberous roots (5.58), the heaviest weight per root (6.13 kg) and the highest yield (61.37 t/ha) were obtained while using the mixture of compost and NPK as fertilizer and “Bonoua” as variety. Thus, mixing compost from chicken manure and NPK can be recommended to improve cassava productivity in Côte d'Ivoire on a ferralitic soil.

Tuğba Güleç | Nevzat Aydın
The aim of this study is to screen the recombinant inbred lines (RILs) carrying rye translocation for the semi-dwarf (Rht), photoperiod (Ppd) and vernalization (Vrn) genes. Recombinant inbred lines were obtained by hybridization of bread wheat varieties Tosunbey and Tahirova-2000. Only the lines carrying 1BL.1RS rye translocation from population were used in the study. Parents and all of RILs were found to have Rht-B1a, which is a semi-dwarf allele, and Ppd-D1a allele, which is not susceptible to photoperiod. The vernalization alleles (Vrn-A1, Vrn-B1 and Vrn-D1) in the lines were also determined. It was determined that both parents and all the RILs had vrn-A1 allele, and not Vrn-A1c allele. It was determined that 151 of RILs contained vrn-B1 allele and 154 of them contained Vrn-B1 allele, while 131 of RILs had vrn-D1 allele and 174 of them had Vrn-D1 allele. In addition, molecular screening were carried out for waxy alleles (Wx-A1, Wx-B1 and Wx-D1) which were effective on flour swelling, water holding capacity and shelf life of bread wheat. As a result of the molecular data it was found that 141 of RILs carry all three alleles and named as “normal amylose wheat” and 164 of them had only Wx-A1 and Wx-D1 alleles, as known “low amylose wheat”. The results indicated that the population used in the research could be the subject of some researches, especially drought tolerance, and RILs could be used to develop genetic material carrying rye translocation for wheat breeding programs.

The aim of this study was to determine the some serum minerals and their interactions between in 2, 3 and 4 years-old healthy Norduz (n=45) and Hair (n=31) goats raised in semi-intensive conditions. Mineral levels were determined with Atomic absorption spectroscopy (AAS) in ppm level. Results were calculated as Fe 1.578±0.088 and 1.379±0.095 mmol/L, Cu 1.300±0.067 and 1.303±0.080 mg/L, Zn 0.972±0.029 and 0.937±0.029 mg/L, K 4.574±0.091 and 2.102±0.074 mmol/L, Mg 2.089±0.057 and 4.670±0.098 mmol/L, Mn 2.163±0.152 and 2.215±0.198 mg/L, Pb 0.078±0.005 and 0.087±0.006 mg/L for Norduz and Hair goats, respectively. While the differences in the mineral levels of hair goats were not significant, significant differences has been found between the age groups in terms of K, F and Pb in Norduz goats. In addition, while there was no statistically significant difference between 3-year-old goats, statistically significant differences hs been found for Fe and 2-year-old goats K and Mg in 4-year-old goats. Moreover, with respect to correlation coefficients, positive correlations were obtained both between K-Mg at Norduz goats and between Fe-Cu, Fe-K, Fe-Mg, K-Mg at Hair goats in all years-old groups.
Afficher plus [+] Moins [-]Effect of Transglutaminase Enzyme on Some Properties of Yogurt Produced from Camel Milk
2020
Selda Bulca | Fahriye Ümüt | Atakan Koç
In this study, microbial transglutaminase (MTGase) enzyme was used to produce yogurt from camel milk. It was reported that camel milk is rich in antimicrobial substances such as lysozyme, lactoperoxidase, lactoferrin and immunoglobulins, which prevent the production of yogurt from camel milk. With the advances in enzymology, it has been suggested that using enzymatic modifications to improve the functional properties and nutritional value of proteins may be effective in the production of yogurt from camel milk. For this purpose, the protein content of camel milk was increased by 6.2% with the addition of sodium caseinate, whey protein concentrate and micellar casein powder. MTGase enzyme was used at concentrations of 3 U and 6 U and the enzyme and the starter culture were added into the camel milk at the same time after that it was left for fermentation. Viscosity, pH and titratable acidity (as lactic acid, %) analyses were performed every hour during fermentation. The increase in viscosity formed as a result of cross-linking with the addition of MTGase enzyme, and the cross-linking formed were determined by decreasing the monomer band intensity of protein fractions with SDS-PAGE. It was found that the higher the MTGase concentration the higher the crosslinking reactions between the amino acids and the higher was the relative viscosity. In addition, the number of yogurt bacteria was determined on both M17 agar and MRS agar to investigate whether yogurt bacteria grow in camel milk and whether their growth is affected by the MTGase enzyme. As a result of the analysis, it was determined that the addition of MTGase enzyme has no suppressive effect on the growth of bacteria.
