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).

Electrophoretic Analysis of DNA Supercoiling Activities.

DNA supercoiling in biological systems can occur via three mechanisms. The first is by the activity of DNA topoisomerases, such as DNA gyrases, that can increase or reduce the linking number of relaxed DNA (Lk). The second is via DNA translocation motors, such as RNA and DNA polymerases, that produce twin supercoiled DNA domains: one positively supercoiled in front and one negatively supercoiled behind.

Environmental predictors of SARS-CoV-2 infection incidence in Catalonia (northwestern Mediterranean).

Numerous studies have explored whether and how the spread of the SARS-CoV-2, the causative agent of coronavirus disease 2019 (COVID-19), responds to environmental conditions without reaching consistent answers. Sociodemographic factors, such as variable population density and mobility, as well as the lack of effective epidemiological monitoring, make it difficult to establish robust correlations. Here we carry out a regional cross-correlation study between nine atmospheric variables and an infection index ( ) estimated from standardized positive polymerase chain reaction (PCR) test cases.

A 25-Year Retrospective of Health IT Infrastructure Building: The Example of the Catalonia Region.

Over the past decades, health care systems have significantly evolved due to aging populations, chronic diseases, and higher-quality care expectations. Concurrently with the added health care needs, information and communications technology advancements have transformed health care delivery. Technologies such as telemedicine, electronic health records, and mobile health apps promise enhanced accessibility, efficiency, and patient outcomes, leading to more personalized, data-driven care.

Variations in antenatal management and outcomes in haemolytic disease of the fetus and newborn: an international, retrospective, observational cohort study.

Background: Advances in haemolytic disease of the fetus and newborn have led to numerous treatment options. We report practice variations in the management and outcomes of haemolytic disease of the fetus and newborn in at-risk pregnancies.

Methods: In this international, retrospective, observational cohort study, data from cases with moderate or severe haemolytic disease of the fetus and newborn were retrieved from 31 centres in 22 countries.
