Research ArticleOpen accessEvery word in the titleEffects 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 · 2,940 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUltrastructural Morphology of the Muscle System Organization in the Trematode Typhlocoelium cucumerinumIrina Yurievna Chidunchi, Ainagul Balgauovna Kaliyeva, Natalya Petrovna Korogod et al.Trematodes, also known as flatworms, are a diverse group of parasitic organisms that live in a variety of ecosystems, from freshwater to marine habitats. Their complex life cycle often involves intermediate and definitive hosts and multiple developmental stages. Trematodes have unique morphological features that allow them to adapt, move and parasitize within host tissues and organs. The parasitic lifestyle of … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 1 Jun 2024 · 5,112 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleEffect of Platelet Rich Plasma on Post Cryopreservation Viability, Morphology and Proliferation of Human Umbilical Cord Stem CellsNoviyanti Goei, Isabella Kurnia Liem, Jeanne Adiwinata Pawitan, Dian MedianaIn most cryopreservation medium, Fetal Bovine Serum (FBS) is used as supplement, while it is well known that FBS contains xenoproteins that can be incorporated into the cells and may be harmfull, as they can elicit immune response. Therefore, finding other xenofree materials as FBS alternative in cryopreservation medium is very important. Platelet Rich Plasma (PRP) is albumin rich and … …OnLine Journal of Biological Sciences, Vol. 15, Issue 2 · 4 Jun 2015 · 7,386 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEXPOSURE TO SWINE HOUSING DUST MODULATES MACROPHAGE MORPHOLOGY AND FUNCTIONRuth J. Pender, Radiah C. Minor, Steven L. Hurley et al.Swine Confinement Facility (SCF) dust consists of a complex mixture of feed grain particles, bacterial components, organic particulates and gases. When these particles are inhaled they deposit along the respiratory tract and mediate respiratory symptoms and disease in swine farmers and facility workers. Macrophages ingest and eliminate microbes and debris under chronic conditions; however, the role of macrophages in agricultural-related … …American Journal of Immunology, Vol. 10, Issue 1 · 25 Mar 2014 · 7,606 accessesView PDFCite
