    Am J Obstet Gynecol 2018 Feb 17. Epub 2018 Feb 17.
    Mater Research Institute - University of Queensland, Level 3 Aubigny Place, Raymond Terrace, South Brisbane, Queensland, Australia, QLD 4101; Mater Mothers' Hospital, Raymond Terrace, South Brisbane, Queensland, Australia, QLD 4101; School of Medicine, The University of Queensland, Brisbane, Australia. Electronic address:
    Background: Small-for-gestational age (SGA) infants (birthweight <10centile) are at increased risk of perinatal complications but are frequently not identified antenatally, particularly in low risk women delivering at term (>37 weeks gestation). This is compounded by the fact that late pregnancy ultrasound is not the norm in many jurisdictions for this cohort of women. We thus investigated the relationship between birthweight <10centile and serious neonatal outcomes in low risk women at term. Read More

    Assistant Professor, Department of Oral and Maxillofacial Surgery, Massachusetts General Hospital, Boston, MA. Electronic address:
    Rhabdomyolysis is a condition in which damaged muscle tissue breaks down and intracellular contents, including myoglobin, are released into the circulation. This produces a nonspecific clinical syndrome including electrolyte disturbances, hypovolemia, metabolic acidosis, coagulopathies, and risk of acute kidney injury. Rhabdomyolysis has been reported as a complication of prolonged surgical procedures but has rarely been reported in the oral and maxillofacial surgery literature. Read More

    Human ASIC1a mediates stronger acid-induced responses as compared with mouse ASIC1a.
    FASEB J 2018 Feb 15:fj201701367R. Epub 2018 Feb 15.
    Department of Physiology and Cell Biology, College of Medicine, University of South Alabama, Mobile, Alabama, USA.
    Acid-sensing ion channels (ASICs) are the major proton receptor in the brain and a key mediator of acidosis-induced neuronal injuries in disease. Most of published data on ASIC function came from studies performed in mice, and relatively little is known about potential differences between human and mouse ASICs (hASIC and mASIC, respectively). This information is critical for us to better interpret the functional importance of ASICs in human disease. Read More

    Mammalian Cells Undergo Endoreduplication in Response to Lactic Acidosis.
    Sci Rep 2018 Feb 13;8(1):2890. Epub 2018 Feb 13.
    Institute of Medical Biology, Agency for Science, Technology and Research (A*STAR), Singapore, Singapore.
    Polyploidization, a common event during the evolution of different tumours, has been proposed to confer selective advantages to tumour cells by increasing the occurrence of mutations promoting cancer progression and by conferring chemotherapy resistance. While conditions leading to polyploidy in cancer cells have been described, a general mechanism explaining the incidence of this karyotypic change in tumours is still missing. In this study, we tested whether a widespread tumour microenvironmental condition, low pH, could induce polyploidization in mammalian cells. Read More

    Intracellular pH Regulation in iPSCs-derived Astrocytes from Subjects with Chronic Mountain Sickness.
    Neuroscience 2018 Feb 10. Epub 2018 Feb 10.
    Department of Pediatrics, University of California San Diego, La Jolla, CA 92093, United States; Department of Neurosciences, University of California San Diego, La Jolla, CA 92093, United States; Rady Children's Hospital-San Diego, San Diego, CA 92123, United States. Electronic address:
    Chronic Mountain Sickness (CMS) occurs in high-altitude residents with major neurological symptoms such as migraine headaches, dizziness and cognitive deficits. Recent work demonstrated that highlanders have increased intracellular pH (pH) in their brain cells, perhaps for the sake of adaptation to hypoxemia and help to facilitate glycolysis, DNA synthesis, and cell cycle progression. Since there are well adapted (non-CMS) and maladapted (CMS) high-altitude dwellers, it is not clear whether pHis differently regulated in these two high-altitude populations. Read More

    8-year retrospective analysis of intravenous arginine therapy for acute metabolic strokes in pediatric mitochondrial disease.
    Mol Genet Metab 2018 Feb 2. Epub 2018 Feb 2.
    Division of Human Genetics, The Children's Hospital of Philadelphia, Philadelphia, PA 19104, USA; Department of Pediatrics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA. Electronic address:
    Background: Intravenous (IV) arginine has been reported to ameliorate acute metabolic stroke symptoms in adult patients with Mitochondrial Encephalopathy with Lactic Acidosis and Stroke-like Episodes (MELAS) syndrome, where its therapeutic benefit is postulated to result from arginine acting as a nitric oxide donor to reverse vasospasm. Further, reduced plasma arginine may occur in mitochondrial disease since the biosynthesis of arginine's precursor, citrulline, requires ATP. Metabolic strokes occur across a wide array of primary mitochondrial diseases having diverse molecular etiologies that are likely to share similar pathophysiologic mechanisms. Read More

    NMR Biomed 2018 Feb 9. Epub 2018 Feb 9.
    Vanderbilt University Institute of Imaging Science, Vanderbilt University, Nashville, TN, USA.
    We have previously reported that the dispersion of spin-lattice relaxation rates in the rotating frame (R) of tissue water protons at high field can be dominated by chemical exchange contributions. Ischemia in brain causes changes in tissue pH, which in turn may affect proton exchange rates. Amide proton transfer (APT, a form of chemical exchange saturation transfer) has been shown to be sensitive to chemical exchange rates and able to detect pH changes non-invasively following ischemic stroke.
