Magnetobiology studies the effects of magnetic fields on biological systems. In this context, the Magnetobiology Research Group at the University of Caldas has hypothesized that magnetic treatment may influence water flow through cell membranes. To contribute to evaluating this hypothesis, this study analyzes the effect of magnetic fields on water transport through TIP3;1 aquaporins of Zea mays L. Molecular dynamics simulation...

Attentionally directed oculomotor training may engage circuits implicated in gamma-band modulation and early Alzheimer’s disease (AD) pathophysiology, yet its effects across mild cognitive impairment (MCI) risk strata remain unclear. We aimed to determine whether this training, delivered through a gamified eye-tracking task, is associated with differential effects on plasma neurodegeneration biomarkers, cognitive performance,...

Background: Patients with a rare genetic disease face unmet needs deepened by the traditional American healthcare system. Social, educational, and financial support resources help address some of these challenges; however, for patients who are Spanish speaking, the language barrier makes it more difficult to attain such resources. This compounds with already existing healthcare disparities faced by the Latino/Hispanic communit...

The invasive brown seaweed Rugulopteryx okamurae represents an ecological challenge in European and Mediterranean coasts. We propose valorizing the biomass collected by incorporating it as a feed ingredient into sustainable aquafeeds. This study evaluated the effects of administering a pulse of biotechnologically treated R. okamurae biomass on muscle composition, gene expression, and intestinal microbiota in the mullet, Chelon...

This study presents the first description and characterisation of Lactococcus garvieae isolated from diseased European sea bass ( Dicentrarchus labrax ) farmed in Spain. During autumn 2023, two fish farms were affected by infectious outbreaks causing moderate cumulative fish mortality (5%–10%). Diseased fish showed clinical signs of haemorrhagic septicaemia, compatible with lactococcosis. Standardised screening tests revealed...

Age is a well-known risk factor to develop severe viral respiratory infections, including severe COVID-19. This study aimed to identify the biological alterations linked to severe disease in elderly patients with COVID-19. For this purpose, we employed a derivation cohort with 450 SARS-CoV-2 infected and unvaccinated patients admitted to hospital wards and a validation cohort with 244 SARS-CoV-2 infected and unvaccinated patie...

The wild boar population in Europe has been growing in recent decades prior to the arrival of African swine fever (ASF), which has now spread across much of eastern Europe. We obtained two independent sources of wild boar data: occurrence sightings and hunting harvest. We combined these with environmental predictors and used them in two species distribution modelling approaches, a Maxent approach for occurrence data and a GLMM...
