Dual role of extracellular vesicles in neurodegenerative diseases.

Extracellular vesicles (EVs) are cell-to-cell interaction tools that are attracting increasing interest in the literature in two opposing areas. In addition to their role in physiological development, there is growing evidence of their involvement in healing and protective processes. However, EVs also mediate pathological conditions, particularly contributing to the progression of several chronic diseases, such as neurodegenerative diseases.

North Atlantic Heat Transport Convergence Derived from a Regional Energy Budget Using Different Ocean Heat Content Estimates.

This study uses an oceanic energy budget to estimate the ocean heat transport convergence in the North Atlantic during 2005-2018. The horizontal convergence of the ocean heat transport is estimated using ocean heat content tendency primarily derived from satellite altimetry combined with space gravimetry. The net surface energy fluxes are inferred from mass-corrected divergence of atmospheric energy transport and tendency of the ECMWF ERA5 reanalysis combined with top-of-the-atmosphere radiative fluxes from the clouds and the Earth's radiant energy system project.

This study investigates the degradation behavior of three distinct Fe-based alloys immersed in three pseudo-physiological solutions. These alloys, which have varied Mn and C contents, include a commercially available Fe-0.15C alloy, namely Fe-C, and two newly developed alloys, that is Fe-5Mn-0.

Applications of basophil activation test in paediatric allergic diseases.

Basophilic granulocytes, containing and releasing histamine after a specific allergy stimulation, are directly involved in IgE-mediated allergic reactions. CD63 is a transmembrane protein of secretory lysosomes of basophils and its upregulation is related with the release of histamine to the extracellular space during IgE-mediated allergic reactions. Basophil activation test (BAT) measures the activation of circulating basophils upon the stimulation of living blood cells with specific allergens.

Electrophoretic fractionations of lipoproteins in dogs: Intra- and inter-assay imprecision and effects of different storage conditions.

An antibody-free bio-layer interferometry biosensor for immunoglobulin G1 detection in human serum by using molecularly imprinted polynorepinephrine.

Bio-Layer Interferometry (BLI) has emerged as a versatile technique in affinity-based biosensing, analogous to Surface Plasmon Resonance. BLI enables real-time, label-free detection, and quantification of biomolecular interactions between an immobilized receptor and an analyte in solution. The BLI sensor comprises an optical fiber with an internal reference layer at the end and an external biocompatible layer where biological receptors are immobilized and exposed to the solution.

Ascertainment of small airway dysfunction using oscillometry to better define asthma control and future risk: are we ready to implement it in clinical practice?

The small airways comprise generations 8 to 23 of the bronchial tree, consist of airways with an internal diameter <2mm, and are classically difficult to assess and treat in persistent asthma. Small airways dysfunction (SAD) is integral to the asthma management paradigm as it is associated with poorer symptom control, greater levels of type 2 inflammation, and has been proposed as a potential treatable asthma trait. Although identification of SAD by oscillometry has been found to be clinically useful in managing asthma, very few physicians, including specialists, use this technique as part of standard or adjunct evaluation of lung function to diagnose asthma, grade severity of airway obstruction, ascertain disease control or the risk for future exacerbations or to make management decisions.

A topographic approach to the markers of macrophage/ microglia and other cell types in high grade glioma.

In glioblastoma, glioma-associated microglia/macrophages (GAMs) represent the major population of tumor infiltrating cells, with up to one half of the cells of the tumor mass. Recent studies have shown that microglia are involved in the maintenance of immunological homeostasis and protection against autoimmunity. However, despite the growing body of evidence on the topic, many aspects are yet to be clarified.

The AβA2V Paradigm: From Molecular Insights to Therapeutic Strategies in Alzheimer's disease and primary tauopathies.

Alzheimer's disease, the leading cause of dementia globally, represents an unresolved clinical challenge due to its complex pathogenesis and the absence of effective treatments. Considering the multifactorial etiology of the disease, mainly characterized by the accumulation of amyloid β plaques and neurofibrillary tangles of tau protein, we discuss the A673V mutation in the gene coding for the amyloid precursor protein, which is associated with the familial form of Alzheimer's disease in a homozygous state. The mutation offers new insights into the molecular mechanisms of the disease, particularly regarding the contrasting roles of the A2V and A2T mutations in amyloid β peptide aggregation and toxicity.
