Research ArticleOpen accessIn the abstractGenetic Testing for Inherited Thrombophilia in Women with Recurrent Pregnancy Loss: Prevalence and Risk Assessment of Factor V Leiden, Prothrombin, and MTHFR MutationsLina M. Al Momani, Manal A. AbbasGenetic testing for inherited thrombophilia in women with recurrent pregnancy loss (RPL) may play an important role in detecting high-risk subjects. DNA was extracted from peripheral blood leukocytes. The high pure polymerase chain reaction template preparation kit and Reverse hybridization technique were used to detect the presence of factor V (G1691A, Leiden) (FVL), Factor II (prothrombin, G20210A), and 5,10-methylenetetrahydrofolate reductase … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 29 Nov 2025 · 2,562 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Dietary Isoleucine Supplementation on the Growth Performance, Carcass Characteristics and Ileal Morphology of Native ChickensCharles Venirius Lisnahan, Oktovianus Rafael Nahak, Lukas PardosiThe roles of isoleucine in the protein synthesis, metabolisms, and growth of chicken have been widely reported. However, its effect on native chicken has not been previously reported. In this work, we reported the effects of dietary isoleucine supplementation on growth performance, carcass characteristics, and ileal morphology in native chickens during the grower phase (6-12 weeks). Two hundred native chickens … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 21 Jun 2025 · 2,945 accessesView PDFCite
