    Hypercalcemia as a rare presentation of angioimmunoblastic T cell lymphoma: a case report.
    J Med Case Rep 2018 Apr 20;12(1):101. Epub 2018 Apr 20.
    Department of Internal Medicine, Wayne State University School of Medicine, Rochester Hills, MI, USA.
    Background: Angioimmunoblastic T cell lymphoma is a rare malignancy, accounting for only 2% of all non-Hodgkin lymphomas, first described in the 1970s and subsequently accepted as a distinct entity in the current World Health Organization classification. Due to the paucity of this disease, there is still no identifiable etiology, no consistent risk factors, and the pathogenesis remains unclear.

    Case Presentation: An 83-year-old Caucasian man presented to an emergency department with palpitations and was found to have atrial fibrillation. Read More

    Synthetic biology-based cellular biomedical tattoo for detection of hypercalcemia associated with cancer.
    Sci Transl Med 2018 Apr;10(437)
    Department of Biosystems Science and Engineering, ETH Zurich, Mattenstrasse 26, CH-4058 Basel, Switzerland.
    Diagnosis marks the beginning of any successful therapy. Because many medical conditions progress asymptomatically over extended periods of time, their timely diagnosis remains difficult, and this adversely affects patient prognosis. Focusing on hypercalcemia associated with cancer, we aimed to develop a synthetic biology-inspired biomedical tattoo using engineered cells that would (i) monitor long-term blood calcium concentration, (ii) detect onset of mild hypercalcemia, and (iii) respond via subcutaneous accumulation of the black pigment melanin to form a visible tattoo.

    J Endocrinol 2018 Apr 9. Epub 2018 Apr 9.
    Y Yoshiko, Oral Grwoth and Developmental Biology, Hiroshima University Graduate School of Biomedical Sciences, Hiroshima, 734-8553, Japan
    The type I transmembrane protein αKlotho (Klotho) serves as a coreceptor for the phosphaturic hormone fibroblast growth factor 23 (FGF23) in kidney, while a truncated form of Klotho (soluble Klotho, sKL) is thought to exhibit multiple activities, including acting as a hormone, but whose mode(s) of action in different organ systems remains to be fully elucidated. FGF23 is expressed primarily in osteoblasts/osteocytes and aberrantly high levels in the circulation acting via signaling through an FGF receptor (FGFR)-Klotho coreceptor complex cause renal phosphate wasting and osteomalacia. We assessed the effects of exogenously added sKL on osteoblasts and bone using Klotho-deficient () mice and cell and organ cultures. Read More

    Insights into calcium-sensing receptor trafficking and biased signalling by studies of calcium homeostasis.
    J Mol Endocrinol 2018 Mar 29. Epub 2018 Mar 29.
    C Gorvin, Institute of Metabolism and Systems Research, University of Birmingham, Birmingham, United Kingdom of Great Britain and Northern Ireland
    The calcium-sensing receptor (CaSR) is a class C G-protein coupled receptor (GPCR) that detects extracellular calcium concentrations, and modulates parathyroid hormone secretion and urinary calcium excretion to maintain calcium homeostasis. The CaSR utilises multiple heterotrimeric G-proteins to mediate signalling effects including: activation of intracellular calcium release; mitogen-activated protein kinase (MAPK) pathways; membrane ruffling; and inhibition of cAMP production. By studying germline mutations in the CaSR and proteins within its signalling pathway that cause hyper- and hypocalcaemic disorders, novel mechanisms governing GPCR signalling and trafficking have been elucidated.

    Background: Multiple myeloma (MM) in dogs typically is treated with melphalan. A daily melphalan dosing schedule reportedly is well tolerated and associated with favorable outcome. Although anecdotally a pulse dose regimen has resulted in successful responses, little long-term outcome and safety data is available regarding this dosing regimen for dogs with MM. Read More

    There have been several studies evaluating the association between vitamin and mineral status and menstrual disturbance. In the present study, we aimed to assess the relationship between the menstrual bleeding pattern and premenstrual syndrome (PMS) symptoms with serum 25-hydroxyvitamin D, and calcium levels in adolescent girls. A cross-sectional study was carried out in 897 high school girls from northeastern Iran. Read More

    The calcium-sensing receptor (CaSR) plays an important role in the homeostasis of serum ionized calcium by regulating parathyroid hormone (PTH) secretion and tubular calcium handling. Calcimimetics, which act by allosteric modulation of the CaSR, mimic hypercalcemia resulting in suppression of PTH release and increase in calciuria. Mostly used in children to treat secondary hyperparathyroidism associated with advanced renal failure, we have shown that calcimimetics can also be successfully used in children with bone and mineral disorders in which elevated PTH plays a detrimental role in skeletal pathophysiology in the face of normal kidney function.
