To read the full abstract: PLoS One. 2018;13:e0191360Up to now most studies to prevent autoimmune T1DM have focused on directly suppressing the autoimmune response rather than to better understanding the intrinsic requirements for beta cell survival. In this trial intracellular heparan sulfate was investigated as an essential requirement for the survival of beta cells and a marker for beta...

To read the full abstract: Sci Transl Med 2017;9(419)Can growth velocity be monitored by a lab test? Previous approaches to this methodological challenge focused on the correlation of linear growth to more established parameters such as C-type natriuretic peptide (CNP). Potentially more specific markers of endochondral ossification - with the exception of amino-terminal propeptide of CNP (...

Brief summary: This study validates dexamethasone-suppressed [11C]metomidate positron emission tomography computed tomography (MTO) scanning as a CYP11B2-selective investigation for lateralizing PA.Primary aldosteronism (PA) is the most common single cause of hypertension, accounting for 5–14% of all cases and 20–25% of treatment-resistant hypertension (1, 2). Traditionally, patients with PA are divided equally into ...
