Faculty of Medicine, Department of Surgery and Physiology, University of Porto, Porto, Portugal; Department of Angiology and Vascular Surgery, Centro Hospitalar de Trás os Montes e Alto Douro, Vila Real, Portugal.

Autogenous arteriovenous fistula (AVF) is the vascular access of choice for chronic kidney disease to patients requiring hemodialysis. However, there still needs to be more consensus on whether the best surgical approach is an end-to-side (ETS) or a side-to-side (STS) anastomosis. This study aims to compare venous maturation rates, midterm patency and postoperative steal syndrome rates between ETS and STS techniques for AVFs.

Phenotypic screening in zebrafish larvae identifies promising cyanobacterial strains and pheophorbide a as insulin mimetics.

Sci Rep

December 2024

Interdisciplinary Centre of Marine and Environmental Research (CIIMAR/CIMAR), University of Porto, Avenida General Norton de Matos, s/n, Matosinhos, 4450-208, Portugal.

Diabetes is a pandemic disease that causes the loss of control of glucose regulation in the organism, in consequence of dysfunction of insulin production or functionality. In this work, the antidiabetic bioactivity of 182 fractions from 19 cyanobacteria strains derived from the LEGE Culture Collection were analysed using the 2-NBDG assay in zebrafish larvae. From this initial screening, two fractions (57 (06104_D) and 107 (03283_B)) were identified as promising insulin mimetics.

December 2024

Food Technology and Safety Division, National Institute for Agricultural and Veterinary Research (INIAV, IP), Quinta do Marquês, 2780-159 Oeiras, Portugal; GeoBioTec - Geobiosciences, Geoengineering e Geobiotechnologies, NOVA School of Science and Technology, Campus de Caparica, 2829-516 Caparica, Portugal.

The aim of this study was to compare two different strains of Pekin duck and to answer one scientific hypothesis: 1) Strain and sex influence live body weight, hot and cold carcass weights and carcass portions weights and yields, fatty acid content, fatty acid total cholesterol and α-tocopherol contents of meat. The study used 50 individuals of each strain in comparison (Cherry Valley and Grimaud) equally divided between both sexes), raised in equal rearing and feeding conditions. The results show that, when raised in equal rearing and feeding conditions and slaughtered at matching age, the strain had no significant influence on live body weight at slaughter, warm and cold carcass weights.

Institute for Artificial Intelligence in Medicine (IKIM), University Hospital Essen (AöR), Essen, Germany.

Objectives: The shape is commonly used to describe the objects. State-of-the-art algorithms in medical imaging are predominantly diverging from computer vision, where voxel grids, meshes, point clouds, and implicit surface models are used. This is seen from the growing popularity of ShapeNet (51,300 models) and Princeton ModelNet (127,915 models).

The management and creation of Marine Protected Areas (MPAs) is currently under great focus, with international organisations aiming to protect 30% of our oceans by 2030. The success of MPAs depends on a nuanced understanding of local ecological dynamics and threats, which can significantly influence ecosystem balance. Herbivory can be a stressor for foundation species, namely kelp forests, contributing to their decline in several regions of the globe.

An automatic system for pathology classification in chest X-ray scans needs more than predictive performance, since providing explanations is deemed essential for fostering end-user trust, improving decision-making, and regulatory compliance. CLARE-XR is a novel methodology that, when presented with an X-ray image, identifies the associated pathologies and provides explanations based on the presentation of similar cases. The diagnosis is achieved using a regression model that maps an image into a 2D latent space containing the reference coordinates of all findings.

Exploring Distinct Second-Order Data Approaches for Thiamine Quantification via Carbon Dot/Silver Nanoparticle FRET Reversion.

Biosensors (Basel)

December 2024

LAQV, REQUIMTE, Department of Chemical Sciences, Laboratory of Applied Chemistry, Faculty of Pharmacy, University of Porto, Rua de Jorge Viterbo Ferreira n° 228, 4050-313 Porto, Portugal.

Accurate and selective monitoring of thiamine levels in multivitamin supplements is essential for preventing deficiencies and ensuring product quality. To achieve this, a Förster resonance energy transfer (FRET) system using carbon dots (CDs) as energy donors and citrate-stabilized silver nanoparticles (AgNPs) as energy acceptors was developed. The aqueous synthesis of AgNPs using microwave irradiation was optimized to obtain efficient plasmonic nanoparticles for FRET applications, targeting maximal absorbance intensity, stability, and wavelength alignment.
