Research ArticleOpen accessIn the abstractComparative Collagen Distribution in the Small Intestine of Eidolon Helvum and Manis TricuspisAdefolaju Gbenga AnthonyThe African tree pangolin has no teeth but consumes a highly tough and chitinous diet while the bat is frugivorous; this study was designed to compare the morphological adaptations of the small intestine of both mammals by investigating the collagen distribution and hydroxyproline/collagen content of their duodenum and ileum histologically and spectrophotometrically respectively. Ten animals each of both sexes were … …OnLine Journal of Biological Sciences, Vol. 19, Issue 3 · 11 Aug 2019 · 7,260 accessesView PDFCite
Research ArticleOpen accessIn the abstractSequence Analysis of Scaffold/Matrix Attachment Regions (S/MARs) From Human Embryonic Kidney and Chinese Hamster Ovary CellsNur Shazwani Mohd Pilus, Azrin Ahmad, Nurul Yuziana Mohd YusofBinding of intergenic Scaffold/Matrix Attachment Regions (S/MARs) to nuclear matrix proteins is believed to poise adjacent genes for transcription by forming chromatin loops. Vector constructs containing Scaffold/Matrix Attachment Regions (S/MAR) flanking the gene of interest, therefore, are able to enhance recombinant protein expression in mammalian cells. We compared two methods that are based on buffers containing 2M NaCl and Lithium-3,5-diidosalicylate … …OnLine Journal of Biological Sciences, Vol. 18, Issue 4 · 8 Oct 2018 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractConservation of Binding of Llama and Other Animals’ Hemoglobins to Haptoglobins Across SpeciesMoges Woldemeskel, Oluseyi A. VanderpuyeThe plasma protein haptoglobin binds hemoglobin released from lysed erythrocytes. It causes removal of the free hemoglobin, thus preventing pathological oxidation of cells. Hemoglobin higher level structures are well conserved across animal species but primary structures can be as little as 50% homologous. Because of these differences, the question arose as to what extent hemoglobins can bind to haptoglobins from … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 26 Jan 2018 · 9,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelative Transcription Expression Level of SIRT1, SIRT2 and SIRT3 in Correlation to the Expression of a Set of Selected Cancer Related Genes in Human Breast CancerHamdy Swelim, Omnia Mansour, Salah Abdel-Rahman et al.Mammalian Sirtuins have been shown to perform distinct cellular functions and deregulated expression of these genes was reported to be involved in the development of various malignancies including breast cancer. An increasing number of evidence indicates that Sirtuins have both tumor promoter and tumor suppressor functions. However, the roles of Sirtuins have not been well-studied in breast cancer. In the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 18 Jan 2018 · 7,476 accessesView PDFCite
Review ArticleOpen accessIn the abstractSpecific Markers for Hepatic Progenitor CellsMsy Rulan Adnindya, Indriyani, Ahmad Azmi Nasution, Isabella Kurnia LiemOne of mammalian organs that has remarkable ability to regenerate, liver, regenerates through the proliferation of hepatocytes or proliferation and differentiation of the stem cells resident. Some literatures states that these stem cells, the Hepatic Progenitor Cells (HPCs), are oval cells that have bipotential ability to be cholangiocytes and hepatocytes. However, the mechanisms of programming, activation of proliferation and maturation/differentiation … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 13 Jul 2017 · 9,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Breeding Seasonality in Rusa Deer (Rusa timorensis) Stags via Serum Testosterone ProfilingWan Nor Fitri Wan Jaafar, Abd Wahid Haron, Rosnina Hj Yusoff et al.Breeding seasonality in mammals is influenced by the environmental changes and the endocrine response of the animals to that changes. Comprehension in breeding seasonality enables better reproductive management consequently maximizing the reproductive potential of the stags. Despite that, the study in breeding seasonality in Rusa deer (Rusa timorensis) is still scarce. Five healthy and matured stags were selected for this … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 19 Mar 2017 · 8,608 accessesView PDFCite
Review ArticleOpen accessIn the abstractMedical Abdominal Visceral Pain in DogsAlice Catanzaro, Giorgia della Rocca, Alessandra Di Salvo, Mary Ellen GoldbergAbdominal visceral pain of medical origin is one of the most frequent reasons for request of medical treatment in humans. Its control is of paramount importance not only for ethical reasons, but also because, if untreated, pain can cause a stress response leading to alterations concerning many organs and apparatuses. Causes of acute or chronic medical visceral pain in men … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 2 · 15 Jun 2015 · 13,992 accessesView PDFCite
Review ArticleOpen accessIn the abstractTransient Receptor Potential Vanilloid 1 Involvement in Animal Pain PerceptionCristina Vercelli, R. Barbero, G. ReIn last decades, Transient Receptor Potential Vanilloid 1 (TRPV1) has been the target of a large number of scientific investigations. It has been identified as a polymodal transducer molecule on a sub-set of primary sensory neurons which responds to various endogenous and exogenous stimuli including noxious heat (more than 42°C), protons and vanilloids such as capsaicin, the hot ingredient of … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 1 · 30 Mar 2015 · 7,266 accessesView PDFCite
EditorialOpen accessIn the abstractGLUTATHIONE: A POSSIBLE LINK TO AUTOPHAGY IN SYSTEMIC LUPUS ERYTHEMATOSUSDilip Shah, Swapan K. NathIncreased free radical formation and altered redox state are of fundamental importance in the pathogenesis of autoimmune diseases including Systemic Lupus Erythematos (SLE). Free radicals are mainly derived from oxygen (Reactive Oxygen Species/ROS) and nitrogen (Reactive Nitrogen Species/RNS) at mitochondria, cellular membranes and the endoplasmic reticulum membrane as physiological responses to a variety of internal and external stress (Shah et … …American Journal of Immunology, Vol. 10, Issue 3 · 3 Sep 2014 · 12,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractCastration and Passive Avoidance Learning Alter the Distribution of N-Methyl D-Aspartate ReceptorSeyed Hassan Mirzaei, Mahnaz Taherianfard, Mina Tadjali, Mahbobeh KohkaloyehIn neurophysiological studies on learning and memory, L-glutamate receptors especially N-Methyl, D-Aspartate glutamate (NMDA) receptors have a major role in different aspect of the learning and memory. Two sites of mammalian brain that show high density of these receptors are CA1 region of hippocampus and Purkinje cell layer of cerebellum. Twenty four Sprague-Dawley rats were used in 4 groups: Control … …Neuroscience International, Vol. 4, Issue 2 · 1 Apr 2014 · 6,773 accessesView PDFCite
