Serological Diagnosis of Infection in Cetaceans by Rapid Serum Agglutination Test and Competitive ELISA with and as Antigens.

Rose Bengal antigen and smooth lipopolysaccharide (s-LPS) were produced from a field strain of ("homologous" antigens) and from the reference strain S99 ("heterologous" antigens); they are currently used for the diagnosis of brucellosis in cattle, water buffaloes, sheep, goats, and pigs, as recommended in the Manual of Diagnostic Tests and Vaccines for Terrestrial Animals of the World Organization for Animal Health (WOAH). "Homologous" and "heterologous" antigens were used in a rapid serum agglutination test (Rose Bengal test, RBT) and a competitive ELISA assay (c-ELISA) to test a panel of sera, blood, and other body fluids (cerebrospinal fluid, pericardial fluid, tracheal fluid, and aqueous humor) collected from 71 individuals belonging to five cetacean species (; ; ; ; and ), which were found stranded on the Italian coastline. Six animals were positive for spp.

Dynamic neurocognitive adaptation in aging: Development and validation of a new scale.

Introduction: Forty-five percent of Alzheimer's disease (AD) cases may have been preventable through protective factors. Reserve, resilience, and resistance share common neurocognitive adaptive processes, acting through protective mechanisms. In this article we propose the development and validation of a new scale, called dynamic Neurocognitive Adaptation, developed in this direction.

Brewers' Spent Grain-Derived Arabinoxylan as a Sustainable Filler for Enhanced PHBV Biocomposites.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a highly promising biodegradable and bio-based thermoplastic recognized for its environmental benefits and potential versatility. However, its industrial adoption has been limited due to its inherent brittleness and suboptimal processability. Despite these challenges, PHBV's performance can be tailored for a wide range of applications through strategic modifications, particularly by blending it with other biodegradable polymers or reinforcing it with natural fibers and bio-based fillers.

Brominated flame retardants in Caretta caretta sea turtles from the Adriatic Sea.

This study evaluated the levels of 10 polybrominated diphenyl ethers (PBDEs) and 3 hexabromocyclododecanes (HBCDDs) in liver and fat tissue of 45 Caretta caretta stranded along the Adriatic Sea. The analytical methodology was based on gas or liquid chromatography coupled with high-resolution mass spectrometry. The mean values of PBDEs and α-HBCDD were 0.
