Extracellular vesicles (EVs) offer valuable diagnostic and prognostic insights for cardiovascular (CV) diseases, but the influence of age-related chronic inflammation ("inflammaging") and sex differences on EV profiles linked to CV risk remains unclear. This study aimed to use EV profiling to predict age and stratify patients by CV risk. We developed an EVaging index by analyzing surface antigen profiles of serum EVs from 625 participants, aged 20 to 94 years, across varying CV risk groups.

- The study focused on replacing NaCO in sodium manganese ferrite with various eutectic or eutectoid alkali carbonate mixtures, which enhanced hydrogen production speed, especially with the (LiNa)CO mixture.
- The fast hydrogen production was linked to the partial melting of the eutectoid carbonate, which facilitates ion diffusion, but this came at the cost of overall reversibility in hydrogen production upon cycling.
- While the nonsubstituted Na mixture displayed the best reversibility, the 50%Li-Na and Li-K-Na mixtures completely failed to produce hydrogen after the first cycle, primarily due to unwanted phase formation and increased sintering in the carbonate mixtures.
Parasites of the genus Sarcocystis can infect several species of animals and cause multiple diseases such as equine protozoal myeloencephalitis. Felines are considered hosts of this protozoa; therefore, the present study aimed to detect anti-Sarcocystis spp.-specific antibodies in domestic cats that were under clinical evaluation, using the indirect immunofluorescence antibody test.

Elevated plasma concentrations of soluble urokinase plasminogen activator receptor (suPAR) provide early warning of progression to severe respiratory failure (SRF) or death, but access to suPAR testing may be limited. The Severe COvid Prediction Estimate (SCOPE) score, derived from circulating concentrations of C-reactive protein, D- dimers, interleukin-6, and ferritin among patients not receiving non-invasive or invasive mechanical ventilation during the SAVE-MORE study, offers predictive accuracy for progression to SRF or death within 14 days comparable to that of a suPAR concentration of ≥6 ng/mL (area under receiver operator characteristic curve 0.
