    Comparison of Chemical and Antimicrobial Properties of Different Nanoparticles Synthesized From Verbascum X Calcicolum Hub.-Mor. Hybrid
    (Elsevier, 2024) Ercan, Leyla; Caliskan, Cemile Gunbegi; Kilic, Murat
    Recent advances in nanoparticle synthesis have led to an increase in the use of environmentally acceptable plantderived nanoparticles, given their wide range of applications. Due to their stability and several advantageous characteristics, selenium nanoparticles also stand out in these investigations in addition to metallic nanoparticles like silver, gold, iron, and zinc. These nanoparticles' favorable qualities for human health, such as antioxidant and antibacterial activities, are being studied in addition to their chemical characteristics. This investigation aimed to produce zinc oxide nanoparticles (VcZnO) and selenium nanoparticles (VcSe) from hybrid Verbascum x calcicolum Hub.-Mor. And to examine their antioxidant and antimicrobial properties. Utilizing the disk diffusion method and well methods, its antibacterial capabilities were studied. In vitro antioxidant capabilities were also assessed utilizing the DPPH, FRAP, and CUPRAC techniques. As a result, it emerged that zinc oxide nanoparticles synthesized from hybrid Verbascum x calcicolum were effective on gram-positive bacteria and gram-negative bacteria such as Staphylococcus aureus (MIC = 160 mg/ml for VcZnO), Pseudomonas aeruginosa (MIC = 80 mg/ml for VcZnO), Klebsiella pneumoniae (MIC = 40 mg/ml for VcZnO and, MIC = 120 mg/ml for VcSe), Escherichia coli (MIC = 20 mg/ml for VcZnO). While selenium nanoparticles are more favorable in terms of antioxidant capabilities, zinc nanoparticles demonstrate stronger antibacterial properties than selenium nanoparticles. Thus, it has been discovered that the use of different nanoparticles of various plants can be more efficient in different applications. It has also been found that Verbascum x calcicolum is a material that can be used successfully in nanoparticle synthesis.

    Genetic Diversity and Population Structure of Anatolian Hair Goats, an Ancient Breed
    (Copernicus Gesellschaft mbH, 2024) Demiray, Aylin; Gunduz, Zuhal; Ata, Nezih; Yilmaz, Onur; Cemal, Ibrahim; Konyali, Aynur; Senyuz, Hasan Huseyin
    This study aimed to investigate the genetic characterization and diversity of Hair goats from 10 regions using 20 microsatellite markers. A total of 522 alleles were observed. The INRA0023 locus exhibited the greatest number of alleles (48), while the DRBP1 locus had the highest effective allele number (16.27), and the BM1818 and DRBP1 loci had the highest polymorphic information content value (0.94). The expected heterozygosity value ranged from 0.85 (ILSTS011) to 0.94 (BM1818, SRCRSP15, and DRBP1). The Hair goat populations in Konya and Hatay displayed the lowest and highest allele numbers, with values of 10.40 and 16.25, respectively. The fixation index (FIS) values are significant in defining population structures and determining the extent of heterozygosity losses. The FIS values exhibited a range of 0.031 in Mu.gla to 0.226 in Burdur. A total of 107 unique alleles were identified in Hair goat populations. However, it is noteworthy that, out of all the alleles, only 25 had a frequency exceeding 5 %. The results indicate that the microsatellite markers utilized demonstrate sufficient levels of polymorphism, making them appropriate for efficiently investigating the genetic variability of Hair goat populations.
