Research ArticleOpen accessIn the abstractMolecular Diagnosis of Toxoplasma gondii in Free-Range Chickens (Gallus gallus) Sold at Fairs in the Metropolitan Region of Macapá–AP (Brazil)Paulo Tarso Tavares Santana, Washington Luiz Assunção Pereira, Rafaelle Casseb Guimarães et al.The informal commercialization of free-range poultry in open markets poses potential food safety risks regarding zoonotic pathogens. This investigation molecularly and histopathologically screened for Toxoplasma gondii in 36 free-range chickens acquired from 12 prominent markets in metropolitan Macapá, Amapá State. Paired heart and brain tissue samples from each animal were processed via conventional PCR and conventional histology. The pathogen was … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 2 Jul 2026 · 1,075 accessesView PDFCite
Research ArticleOpen accessIn the abstractAluminium-Induced Hepatotoxicity and the Protective Role of Withania somnifera (Ashwagandha) in Wistar RatsAnchana Babu, Rekha D Kini, Nayanatara Arun Kumar, Megha GokulAluminium is a widely distributed environmental contaminant whose chronic exposure leads to accumulation in multiple organs, including the liver, resulting in oxidative stress and tissue damage. When reactive oxygen species production exceeds the body's antioxidant defense capacity, cellular injury ensues — a mechanism central to aluminium-induced hepatotoxicity. Withania somnifera (Ashwagandha), an evergreen herb of the Solanaceae family widely cultivated in … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 6 Apr 2026 · 1,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Renoprotective Effects of Valsartan in Methotrexate-Induced Acute Kidney Injury in RatsDina KutbiMethotrexate (MTX) is a widely used chemotherapeutic agent known for its nephrotoxic effects, which can lead to acute kidney injury in hospitalized patients. However, the mechanism by which MTX induces nephrotoxicity is not entirely clear, but it is believed to involve oxidative stress and direct toxic effects on renal tubules. Valsartan, an angiotensin II receptor blocker, has been shown to … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 4 May 2024 · 4,571 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural 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 accessIn the abstractA Static Magnetic Field Exposure in Obese Mice Induced by High Fat Diet: Its Effect on T-Box15 Gene and Uncoupling Protein 1 ExpressionWidia Bela Oktaviani, Puji Sari, Luluk Yunaini et al.Increased Ca2+ cytosolic concentration caused by Static Magnetic Field (SMF) exposure modulates Tbx15 protein and Ucp1 gene interaction that is involved in the thermogenesis browning process of white adipose tissue. Activation of Tbx15 as a transcription factor that regulates the expression of the Uncoupling protein 1 (Ucp1) gene induced by SMF exposure in adipose tissue converts excess accumulated fat into … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 23 Jan 2024 · 4,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrocystin-LR Affects Ultimobranchial Gland of Catfish Heteropneustes fossilisChandra Prakash, Sunil Kumar SrivastavMicrocystin-LR (2.5 µg/25 g) was injected intraperitoneally to the fish Heteropneustes fossilis on day 1, 10 and 20 kept in either freshwater or freshwater containing ZnCl2. The fishes were killed on day 5, 10, 20 and 30 day. The serum calcium levels was estimated and ultimobranchial glands were processed for routine histology. Microcystin-LR administration to fish Heteropneustes fossilis induced hypocalcemia … …American Journal of Environmental Sciences, Vol. 17, Issue 3 · 5 Jul 2021 · 6,215 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafety Assessment of Indigenous Probiotic Strain Lactobacillus plantarum Mut-7 Using Sprague Dawley Rats as a ModelAtika Yahdiyani Ikhsani, Emma Riftyan, Rosa Amalia Safitri et al.Lactobacillus plantarum Mut-7 is a probiotic candidate isolated from gatot, traditional fermented cassava from Java, Indonesia. This study aimed to evaluate safety aspects of high dose consumption of L. plantarum Mut-7 (1011 CFU/ml/day) on Sprague Dawley rats for 21 days. Twenty four female rats were randomly divided into 4 groups; initial condition group (P.0), control group (P.1), skim milk group … …American Journal of Pharmacology and Toxicology, Vol. 15, Issue 1 · 30 Apr 2020 · 8,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferent Eye Physiology of Mud Crab (Scylla Serrata) in Different Life Stage Found in Semarang Territorial WatersAristi Dian Purnama Fitri, Herry Boesono, Agus Sabdono, Fahresa NugraheniMud crabs use their eyes function to guide their movement activities i.e., to avoid predator and to support their environment orientation. In tropical environment such as Indonesia, mud crabs live in mangrove area as their habitat. To support their visual acuity, mud crabs depend on the number of con sell as photoreceptor and carapace width. The purpose of this study … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 1 · 27 Jan 2018 · 8,809 accessesView PDFCite
