RNA profiles differ between small and large extracellular vesicle subsets isolated from porcine seminal plasma.

Background: Extracellular vesicles (EVs) are essential for cell-to-cell communication because they transport functionally active molecules, including proteins, RNA, and lipids, from secretory cells to nearby or distant target cells. Seminal plasma contains a large number of EVs (sEVs) that are phenotypically heterogeneous. The aim of the present study was to identify the RNA species contained in two subsets of porcine sEVs of different sizes, namely small sEVs (S-sEVs) and large sEVs (L-sEVs).

The RNA-binding protein Modulo promotes neural stem cell maintenance in Drosophila.

A small population of stem cells in the developing Drosophila central nervous system generates the large number of different cell types that make up the adult brain. To achieve this, these neural stem cells (neuroblasts, NBs) divide asymmetrically to produce non-identical daughter cells. The balance between stem cell self-renewal and neural differentiation is regulated by various cellular machinery, including transcription factors, chromatin remodelers, and RNA-binding proteins.

Toward a Plasmon-Based Biosensor throughout a Thermoresponsive Hydrogel.

This study investigates the potential of thermoresponsive hydrogels as innovative substrates for future in vitro diagnostic (IVD) applications using AVAC technology, developed and patented by the Mecwins biomedical company. In order to convert the hydrogel in a substrate compatible with AVAC technology, the following prerequisites were established: (1) the hydrogel layer needs to be permeable to gold nanoparticles (AuNPs), and (2) the optical properties of the hydrogel should not interfere with the detection of AuNPs with AVAC technology. These two key aspects are evaluated in this work.

Degenerateness, Mental Hygiene, and Spiritism: Debates in the Argentine Medical Press (1930-1946).

The disputes between spiritualists and physicians occurred in the context of hygienism and the degeneration theory, where spiritualists were considered agents requiring health care by alienists and psychiatrists. French psychiatry defended this interpretation to isolate and treat "spiritual delirium," which came to have considerable importance in the debates between spiritism and psychiatry. Specifically, pathologization and psychologization became strategies to deal with the disruptive experience of mediumship and the sense of threat from spiritualism.
