X-ray crystallography is a robust and powerful structural biology technique that provides high-resolution atomic structures of biomacromolecules. Scientists use this technique to unravel mechanistic and structural details of biological macromolecules (e.g., proteins, nucleic acids, protein complexes, protein-nucleic acid complexes, or large biological compartments). Since its inception, single-crystal cryocrystallography has never been performed in Türkiye due to the lack of a single-crystal X-ray diffractometer. The X-ray diffraction facility recently established at the University of Health Sciences, İstanbul, Türkiye will enable Turkish and international researchers to easily perform high-resolution structural analysis of biomacromolecules from single crystals. Here, we describe the technical and …

Age estimation of the juvenile stage of Varanus salvator bivittatus using limb bones, namely the big long tubular bones (femur, tibia, humerus) and the small long tubular bones (fibula, radius, ulna, phalanx), was performed using the skeletochronological method. Samples were from Java Island, Indonesia and provided by the pet exporters. Lines of arrested growth (LAG) were present and the first growth mark was visible on a female with a snout-vent length (SVL) of 18.8 cm, and a male with SVL of 19.3 cm. The process of resorption begins in the juvenile stage, and resorption occurs in all long tubular bones. …

The aim of the study was to trace the influence of several abiotic factors on the distribution of the mesozooplankton community from the Black Sea. Sampling was performed in cold and warm seasons of 2013-2020, from stations located on the three sectors of the Romanian Black Sea coast (northern-N, central-C, and southern-S). After determining the species composition, abundance, and biomass, the results were subjected to statistical analysis. A total of 25 taxa were identified, Copepoda representing the bulk of the community. The analysis of the main components explains, through the first two identified factors-temperature and salinity, the variation of environmental …

Despite the increasingly obvious sex differences, male animals are still predominantly used to study stress and related disorders. The aim of this study was to evaluate the effects of repeated noise stress in female and male mice. In the experiment, 12 male and 12 and female SPF/VAF 6-week-old Crl:CD1(lcr) mice were used. After 5 days of acclimatization all animals were placed in the open-field for three consecutive days where each mouse spent 10 min daily without any noise treatment in order to get used to the circumstances of the test. On day 9 to record baseline behaviour the animals were …

The present study aimed to analyse the gestation length (GL) variability in locally born purebred Holstein dams (n = 1047), in a private farm, under Saharan climate. The overall GL mean was 278.73 ± 6.67 days. A general linear model revealed that the GL was significantly affected by calf sex (p = 0.035) with a minor increase of 0.19% in males, dam parity (p = 0.016) and calving season (p < 0.0001) including the shortest lengths recorded in heifers and during heat stress period. Moreover, a negative regression (-1.96%) in recent years was recorded in GL by the influence (p = 0.01) of years of birth, breeding, and calving of cows. Our findings show that cows that were inseminated and gave birth during the cold season (temperature-humidity index, THI < 74) had 11.54 days longer (p = 0.048) gestation period compared to animals that were inseminated and gave birth during the hot season (THI > 84). Similarly, the association (p = 0.003) between dam parity and calf sex revealed that the GL of multiparous cows that gave birth to male calves was higher (3.07 days) …
