Morphometric Analysis Of The Skulls Of Domestic Cattle (Bos Taurus L.) And Water Buffalo (Bubalus Bubalis L.) In Turkey, Ermi̇ş Özkan, Abu Bakar Siddiq, Ki̇fayet Oya Kahveci̇oğlu, Muhsi̇n Öztürk, Vedat Onar
Turkish Journal of Veterinary & Animal Sciences
A total of 20 domestic cattle (Bos taurus L.) and 15 water buffalo (Bubalis bubalis L.) skulls were analyzed in this study. All of the specimens belonged to female individuals. Using a total of 27 craniometric measurements from each of the skulls, 9 indices were calculated. Although there were statistically significant differences between the linear measurements of the skulls of both species, while calculating the indices with their ratios, the values of the measurements of the facial area were determinative in the craniology. Among these indices, the facial index 1 value was statistically significant (P < 0.01) in the comparison of these two species. On the other hand, while considering the orbit and foramen magnum measurements, in contrast with the transversal measurement, the height was more determinant for their index and form.

Chemical Composition And In Vitro Rumen Fermentation Of Ensiled Sugar Industry Coproducts, Zohreh Zarnegar, Seyed Hadi Ebrahimi, Abbas Ali Naserian, Reza Valizadeh
Turkish Journal of Veterinary & Animal Sciences
he current study aims to compare sugar beet leaves (SBLs) ensiled with sugar beet pulp (SBP), sugarcane molasses (SM), or rock candy juice (RCJ) using an in vitro gas production technique. Treatments in the first group included 10% SBP (control 1) and control 1 plus 5% SM or RCJ. In the second group, there were 3 treatments, including 20% SBP (control 2) and control 2 plus 10% SM or RCJ. The silages with no added soluble carbohydrate (SC) sources had significantly higher (P < 0.001) pH, buffer value index, and ammonia nitrogen values than the other treatments. However, there was no significant difference between RCJ and SM in their effect on these variables. Adding both levels of SC sources caused an increase in dry matter digestibility compared to those that only included SBL and SBP (P < 0.001). Maximal and rate of gas production from slowly fermentable fraction (a$_{2}$) were significantly greater when the substrate contained 85%, 10%, and 5% SBL, SBP, and SC sources, respectively. Using dried SBP and SC sources for the preservation of fresh SBL is recommended; however, with higher levels of SC, the silage may be at risk of spoilage, and it must be less exposed to air.

Protonation Behavior Of Dextran Amino Acid Esters, Konrad Hotzel, Lidjia Fras Zemljic, Matej Bracic, Thomas Heinze
Turkish Journal of Chemistry
Dextran esters of different amino acids (glycine, $\beta $-alanine, L-ornithine, L-lysine) are investigated regarding their pK$_{a}$ values by potentiometric titration. The pK$_{a}$ values of the dextran derivatives are generally dependent on the position of the amino group in relation to the ester group, i.e. the nearer they are located in the molecule, the lower the resulting pK$_{a}$ values are, L-ornithine ester being the exception. An influence of the polymer backbone is ruled out. Stability against hydrolysis at different pH values and over longer periods at constant pH value is measured by potentiometric and polyelectrolyte titration. The $\beta $-alanine ester shows …

Anticancer activity of the compounds was determined by MTT (0.5, 5, and 50 $\mu $g/mL) and lactate dehydrogenase (LDH) release assays against human prostate and breast cancer cells. Oxidative status of cells was elicited by total oxidative stress and total antioxidant capacity methods. Chick chorioallantoic membrane assay was used to evaluate the antiangiogenic activity. Genotoxicity was evaluated by the sister chromatid exchange (SCE) and micronucleus (MN) tests in lymphocyte cultured human blood. Our results …

Lard is defined as animal fat acquired from the adipose tissue of pigs and is not permitted for human consumption or external use by certain religions such as Islam and Judaism. Due to its low-cost availability for commercial use, it is often mixed with other vegetable oils mistakenly or deliberately and causes loss of consumer trust; hence, its detection in food products is essential. Consumers tend to know the authenticity of commercially available edible oils. However, edible oils are subjected to adulteration risks with lard, which breaches consumer rights. In the present study, we designed a transmission Fourier transform infrared …

A series of sulfonamide derivatives were synthesized by reactions with various functional groups containing benzenesulfonyl chlorides and aniline derivatives under different substitution reaction conditions. The structures of SMZ derivatives were confirmed with melting point, FT-IR, $^{1}$H NMR, $^{13}$C NMR, and LC-MS/MS techniques. In order to investigate the cytotoxic effects of these derivatives, we used a model plant species. The synthesized compounds (S1-S5) and sulfamethazine (SMZ) as a positive control were applied to Arabidopsis thaliana seeds. Our results indicated that S3 and S4 induced shorter roots and lower wet weight in plants. Plants treated with S2 and S5 showed no growth …
