Evaluation Of Antioxidant Activity Of Bee Products Of Different Bee Races In Turkey, Özlem Saral, Mehmet Kiliçarslan, Hüseyi̇n Şahi̇n, Oktay Yildiz, Barbaros Di̇nçer
Turkish Journal of Veterinary & Animal Sciences
Bee products with high bioactive properties have a very important place in human nutrition. Biochemical properties of these products such as honey, pollen, and propolis vary according to flora, season, bee race, and production methods. In this study, the biological activities of honey, bee pollen, and propolis samples from four bee races in Turkey (Apis mellifera caucasica, Apis mellifera anatoliaca, Apis mellifera syriaca, and Apis mellifera carnica) were examined. Besides the determining of total polyphenol and total flavonoid contents, the antioxidant capacity was investigated by three different assays: DPPH (1,1-diphenyl-2-picrylhydrazyl) radical-scavenging activities, CUPRAC (cupric reducing antioxidant capacity) and FRAP (ferric …

Analysis Of Spermatogenesis In Young Male Hybrids Bred From Domestic Cattle(Bos Taurus) And European Bison (Bison Bonasus), Andrzej Zyczynski, Marta Kloch, Wanda Olech
Turkish Journal of Veterinary & Animal Sciences
A new attempt was undertaken to check the reproductive capabilities of male hybrids bred from European bison (Bison bonasus) and domestic cattle (Bos taurus). The analysis concerned two hybrids aged 1.5?2.5 years (the latter being sampled twice at 6-month intervals), and additionally one 1.5-year-old backcross hybrid. Examination of testicular tissue revealed halting of spermatogenesis, which was hardly ever able to proceed further than meiosis I. Spermatogenesis was arrested at the stage of spermatogonia and primary spermatocytes. Spermatozoa were found only in the case of one hybrid and these were mostly malformed. To summarize, all the males studied were sterile, despite …

Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to evaluate the serological diagnostic potential of the Brucella recombinant outer membrane (rOMP25, rOMP31) and periplasmic proteins (rBP26, rSOD) in a comparative way using an indirect enzyme-linked immunosorbent assay (i-ELISA). Rabbit and/or mouse antibodies to Brucella whole cell and/or soluble protein preparations recognized all recombinant proteins used, which confirms the expression of target antigens in E. coli in active form. The recombinant proteins showed different antigenicity to antibodies of cattle kept on a brucellosis-affected (endemic) farm and/or a new focus of infection. Thus, the presence of anti-Brucella antibodies was confirmed by i-ELISA/rSOD in 79% …
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
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.

Turkish Journal of Zoology
Within its range, the Caspian green lizard, Lacerta strigata, occurs in the Elburz Mountains (northern Iran) at elevations from below sea level to approximately 2700 m a.s.l. To determine the environmental factors affecting the distribution of this lizard, we used an ensemble approach to model the distribution of the Caspian green lizard (Lacerta strigata) in Iran using four algorithms (generalized boosted model, maximum entropy, generalized linear model, random forest). Results revealed that low-elevation habitats between the Elburz Mountains and the Caspian Sea are the most suitable habitats for the species. The normalized difference vegetation index (NDVI), annual precipitation (both with …

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.

First Evidence Of Holocrine Secretory Mechanism In Granular Ducts Inmouse Mandibular Gland, Bianca Matosz, Flavia Ruxanda, Cristian Ratiu, Vlad Luca, Vasile Rus, Viorel Miclaus
Turkish Journal of Veterinary & Animal Sciences
The mouse mandibular gland contains granular ducts, which possess a particular structure. They are termed granular ducts because they contain numerous granules in the cells lining them, having a secretory activity. We aimed to assess the secretory mechanism in granular ducts. Consequently, we harvested the mandibular glands from five male mice and processed them for histological investigations. A large number of cells appeared intact, without obvious distortions or disruptions in the cell membrane. Based on the morphological aspect, these cells either transferred the secretory product through exocytosis or were in "standby" mode. There were cells that presented prominent bulges of …

Competitiveness Of Generalist Plant Populations At A Mine Site, Justin S.H. Wan, Fati̇h Fazlioğlu, Stephen P. Bonser
Competitiveness Of Generalist Plant Populations At A Mine Site, Justin S.H. Wan, Fati̇h Fazlioğlu, Stephen P. Bonser
Turkish Journal of Botany
Plants inhabiting extremely stressful mine site environments tend to be specialized and localized, where they express lower performance than nonmine site plants from adjacent areas. However, such a cost may be concealed. In a previous study at a mine site, we found mine and adjacent nonmine plants of multiple species expressed similar performances in the absence of competition. However, a lower competitive ability may be a concealed driver. We aim to test whether costs under competition could explain specialization. In a glasshouse experiment, we measured the performance (i.e. vegetative and reproductive growth) of mine and nonmine potted plants under competition. …

A Multiple Epidermis Or A Periderm In Parkinsonia Praecox (Fabaceae), Silvia Aguilar-Rodriguez, Teresa Terrazas, Xicotencatl Camacho-Coronel
Turkish Journal of Botany
A multiple epidermis in the green stems of Parkinsonia species has been described; however, there are disagreements among authors with regard to origin and tissues involved. The aims of this study were to identify the origin and development of the epidermis and cortex of P. praecox and relate these to possible adaptations to arid environments. Samples from new branches, to the stem, were removed and prepared using two embedding techniques. Our results show that the epidermis is simple, but periclinal divisions start far from the apical meristem. The inner derivatives maintained periclinal and anticlinal divisions, which are interpreted as meristematic, …

Lead can cause morphological and functional changes in heart, and inflammation and endothelial dysfunction in vasculature. Endocan, as a novel indicator of endothelial dysfunction, has been used for cardiovascular diseases. This study investigated the relationship between lead exposure, endocan levels, and diastolic functions.Materials and methods: A total of 51 lead-exposed workers without a known cardiovascular disease or risk factors and 54 healthy controls were enrolled. All participants underwent transthoracic echocardiography. Blood lead and serum endocan levels were analyzed.Results: Baseline demographic and clinical characteristics were found to be similar between groups. Median blood lead (32 vs 1.5 µg/dL, P < 0.001) and serum endocan levels (67 vs 57.1 pg/mL, P = 0.02) were significantly higher in the lead-exposed group. Serum endocan level showed a positive correlation with blood lead levels (r = 0.404, P = 0.003) in lead-exposed workers. Serum endocan level was an independent risk factor for increased E/E' ratio (ß = 0.704, P = 0.002) and left atrial volume index (ß = 1.158, P = 0.011) and higher level of lead in blood was an independent risk factor for increased E wave (ß = 8.004, P = 0.022) in lead-exposed workers. Conclusion: Worsened diastolic functions may be seen in the course of lead exposure. Due to sharing a similar mechanism, a higher serum level of endocan may be a valuable laboratory clue for impaired diastolic function in this population.

Background/aim: Diminished ovarian reserve (DOR) represents a major challenge in reproductive medicine, as it is often associated with poor ovarian stimulation response, high cycle cancellation rate, and low pregnancy rate. The aim of the present study is to compare the clinical pregnancy rates in intracytoplasmic sperm injection-embryo transfer (ICSI-ET) cycles in patients with different DOR etiologies. Materials and methods: Patient data were recorded with a computer-based program called Success Estimation Using a Ranking Algorithm (SERA). Overall, 459 patients were divided into 3 groups according to their DOR etiologies (Group A: idiopathic, n = 81; Group B: age-related, n = 294; …

Background/aim: The present study aimed to examine whether the combination of neoadjuvant volumetric modulated arc radiotherapy (VMAT) using simultaneous integrated boost (SIB-VMAT) techniques and chemotherapy with capecitabine is associated with better clinical and dosimetric outcomes compared to the standard treatment.Materials and methods: The study included 59 patients with cT2?T4 rectal cancer. In the standard arm, patients (n = 37) were treated preoperatively with image-guided VMAT plus capecitabine. In the SIB arm, patients (n = 22) were treated with the SIB-VMAT technique plus capecitabine. All patients underwent radical surgical resection after neoadjuvant radiochemotherapy. Results: In the standard arm, cT0N0 was reached …
