Deciphering opening mechanisms of 14‐3‐3 proteins

Protein Science, Volume 34, Issue 4, April 2025.
Abstract The 14‐3‐3 proteins are a highly conserved family of regulatory molecules that play crucial roles in various cellular processes. They are known for their ability to bind to phosphorylated serine and threonine residues on target proteins, which allows them to modulate their activity, localization, and stability.

Melanisation in Salmonid Skeletal Muscle: A Review

Journal of Fish Diseases, Volume 48, Issue 3, March 2025.
ABSTRACT Melanisation can occur in the musculature of fish. A well‐known form is the melanised focal changes, or ‘black spots’, in the fillet of farmed Atlantic salmon (Salmo salar). The aetiology of black spots has not been fully determined, though recent research has emphasised the role of fat necrosis in their development.

Full‐spectrum cannabidiol reduces UVB damage through the inhibition of TGF‐β1 and the NLRP3 inflammasome

Photochemistry and Photobiology, Volume 101, Issue 1, Page 83-105, January/February 2025.
Photoprotective and antiinflammatory benefits of full‐spectrum cannabidiol (FS‐CBD) against UVB‐induced cellular death were examined in this study. FS‐CBD protected against UVB‐induced bacterial death for 30 min. FS‐CBD protected against UVB‐induced cells, in an in vitro keratinocyte cell model.

Evaluating use of two‐step International Ovarian Tumor Analysis strategy to classify adnexal masses identified in pregnancy: pilot study

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 6, Page 808-817, December 2024.
ABSTRACT Objectives The primary aim was to validate the International Ovarian Tumor Analysis (IOTA) benign simple descriptors (BDs) followed by the Assessment of Different NEoplasias in the adneXa (ADNEX) model, if BDs cannot be applied, in a two‐step strategy to classify adnexal masses identified during pregnancy. The secondary aim was to describe the

Microalgae and cyanobacteria as microbial substrate and their influence on the potential postbiotic capability of a bacterial probiotic

Microbial Biotechnology, Volume 17, Issue 11, November 2024.
Postbiotic are bacterial metabolites, including extracellular products (ECP), and can be affected by various factors such as cultivation conditions which influence bacterial metabolism. The present work uses a microalgae‐/cyanobacteria‐supplemented media as a novel substrate for growing the probiotic Shewanella putrefaciens SpPdp11, analysing and ...

In vitro exposure of porcine sperm to functionalized superparamagnetic nanoparticles

Reproduction in Domestic Animals, Volume 59, Issue S3, October 2024.
Abstract Nanotechnology and its applications have advanced significantly in recent decades, contributing to various fields, including reproduction. This study introduces a novel method to label porcine oocytes with nanoparticles (NPs) bound to oviductin (OVGP1, Ov) for use in Assisted Reproductive Technologies (ARTs).
