Location and function of TDP-43 in platelets, alterations in neurodegenerative diseases and arising considerations for current plasma biobank protocols.

The TAR DNA Binding Protein 43 (TDP-43) has been implicated in the pathogenesis of human neurodegenerative diseases and exhibits hallmark neuropathology in amyotrophic lateral sclerosis (ALS). Here, we explore its tractability as a plasma biomarker of disease and describe its localization and possible functions in the cytosol of platelets. Novel TDP-43 immunoassays were developed on three different technical platforms and qualified for specificity, signal-to-noise ratio, detection range, variation, spike recovery and dilution linearity in human plasma samples.

Unveiling therapeutic potentials and exploring maternal-fetal health benefits of metformin in pregnancy: A scoping review.

This scoping review synthesizes evidence on metformin's use during pregnancy, encompassing diverse conditions like gestational diabetes, type 1 and type 2 diabetes, polycystic ovary syndrome (PCOS), and obesity. Metformin demonstrates comparable efficacy to insulin in gestational diabetes, positive outcomes in type 2 diabetes pregnancies, and potential benefits in reducing complications. The review highlights nuances in its effects across conditions, indicating advantages such as reduced risk of macrosomia and cesarean section in gestational diabetes.
