    A Nonredundant Role for the TRPM6 Channel in Neural Tube Closure.
    Sci Rep 2017 Nov 15;7(1):15623. Epub 2017 Nov 15.
    Rutgers-Robert Wood Johnson Medical School, Deptartment of Pharmacology, Piscataway, 08854, USA.
    In humans, germline mutations in Trpm6 cause autosomal dominant hypomagnesemia with secondary hypocalcemia disorder. Loss of Trpm6 in mice also perturbs cellular magnesium homeostasis but additionally results in early embryonic lethality and neural tube closure defects. To define the mechanisms by which TRPM6 influences neural tube closure, we functionally characterized the role of TRPM6 during early embryogenesis in Xenopus laevis. Read More

    Is endothelin gene polymorphism associated with postoperative atrial fibrillation in patients undergoing coronary artery bypass grafting?
    Ann Card Anaesth 2017 Jul-Sep;20(3):341-347
    Department of Biostatistics, All Institute of Medical Sciences, New Delhi, India.
    Background: The mechanism of development of atrial fibrillation (AF) in patients undergoing coronary artery bypass grafting (CABG) has not been clearly defined, and the involvement of multiple factors such as advanced age, withdrawal of β-blockers, inadequate atrial protection, and electrolyte imbalance, particularly hypomagnesemia has been documented by several authors. Despite all the available pharmacologic prophylaxis, incidence of AF still remains high in this group of patients. This unexplained cause could be genetic inheritance of endothelin-1 (ET-1) gene which is thought to have a pro-arrhythmogenic effect. Read More

    [Magnesium in daily practice].

    Ionized magnesium in plasma and erythrocytes for the assessment of low magnesium status in alcohol dependent patients.
    Drug Alcohol Depend 2017 Sep 24;178:271-276. Epub 2017 Jun 24.
    Department of Psychiatry, Medical University of Warsaw, Poland.
    Background: Studies on the homeostasis of magnesium in alcohol-dependent patients have often been characterized by low hypomagnesemia detection rates. This may be due to the fact that the content of magnesium in blood serum constitutes only 1% of the average magnesium level within the human body. However, the concentration of ionized magnesium is more physiologically important and makes up 67% of the total magnesium within a human organism. Read More

    Clinical aspects of magnesium physiology in patients on dialysis.
    Semin Dial 2017 Sep 13;30(5):438-445. Epub 2017 Jun 13.
    Division of Nephrology, Jewish General Hospital, McGill University, Montreal, QC, Canada.
    Magnesium balance is infrequently discussed in the dialysis population, and the clinical consequences of derangements in magnesium homeostasis are incompletely understood. There is an association between hypomagnesemia and adverse outcomes including increases in cardiovascular disease and mortality, while elevated magnesium levels have also been linked with complications such as osteomalacia. In this review, we discuss the features of magnesium physiology relevant to dialysis patients and provide an updated summary of the literature linking magnesium derangements with bone disease, cardiovascular disease, sudden cardiac death, and mortality.

    Claudin Loss-of-Function Disrupts Tight Junctions and Impairs Amelogenesis.
    Front Physiol 2017 24;8:326. Epub 2017 May 24.
    Laboratory Orofacial Pathologies, Imaging and Biotherapies, Dental School, Paris Descartes University, Sorbonne Paris CitéParis, France.
    Claudins are a family of proteins that forms paracellular barriers and pores determining tight junctions (TJ) permeability. Claudin-16 and -19 are pore forming TJ proteins allowing calcium and magnesium reabsorption in the thick ascending limb of Henle's loop (TAL). Loss-of-function mutations in the encoding genes, initially identified to cause Familial Hypomagnesemia with Hypercalciuria and Nephrocalcinosis (FHHNC), were recently shown to be also involved in Amelogenesis Imperfecta (AI).

    Multicenter Phase II Study of Panitumumab in Platinum Pretreated, Advanced Head and Neck Squamous Cell Cancer.
    Oncologist 2017 Jul 7;22(7):782-e70. Epub 2017 Jun 7.
    Oncology Institute of Southern Switzerland, San Giovanni Hospital, Bellinzona, Switzerland.
    Lessons Learned: Panitumumab shows activity in terms of disease control rate and preventing disease progression but not for tumor shrinkage in head and neck squamous cell cancer for second-line treatment. Epidermal growth factor receptor (EGFR) copy number gain, a property of tumor cells that theoretically could identify patients more likely to experience disease response, was common among patients having disease control.Our trial, given the lower toxicity with an every-2-week schedule, provides guidance for future trials, for example, in combinations of immune therapies and anti-EGFR-antibodies.

    Hepatocyte nuclear factor 1 homeobox B (HNF1β) is an essential transcription factor for the development and functioning of the kidney. Mutations in HNF1β cause autosomal dominant tubulointerstitial kidney disease characterized by renal cysts and maturity-onset diabetes of the young (MODY). Moreover, these patients suffer from a severe electrolyte phenotype consisting of hypomagnesemia and hypokalemia. Read More
