Summary: Shallow and coastal aggregations of batoids are not well-documented in the Mediterranean Sea, despite the potential threats they face. This study reports the first observations of a potential summer reproductive aggregation of the common stingray in Scilla Bay, Italy. The presence of pregnant females, a mature male, and a female with fresh bite wounds suggests that this area could serve as an important site for parturition and mating, highlighting the significance for conservation efforts of this Vulnerable species.

Summary: This study investigates the presence of mono-, di-, and trihydroxy PUFA-GPCs in plasma lipoproteins and their hydrolysis by different sPLA(2)s enzymes. It was found that lipoproteins contain varying amounts of polyhydroxy-PUFA-GPC, likely the product of lipid peroxidation and the action of enzymes. Interestingly, the trihydroxy-16:0/PUFA-GPC was largely absent in one type of HDL, while unidentified material was present in the same area. LC/ESI-MS analysis showed agreement between the masses of polyhydroxy PUFA-GPC and the calculated masses for related GPCs.

Summary: This study focuses on finding new catalysts for the oxidation reaction of catechol to o-quinone. Seven quinoline-based compounds were investigated, and it was found that complexes formed with Cu(OAc)(2) showed higher catalytic activity compared to Cu(NO3)(2) and CuCl2 complexes. The oxidation rate depends on the chemical structure of the ligands and the nature of the coordinated ions.

Summary: Rodent models are useful for studying the potential connection between autism spectrum disorder (ASD) and gut microbiota, as autistic patients often experience gastrointestinal problems. In this study, 30 young male rats were divided into different groups and treated with bee pollen and probiotics to investigate the effects on gut health and oxidative stress markers. The results showed that the combination treatment significantly improved leaky gut biomarkers and reduced oxidative stress levels in rats exposed to propionic acid, which is associated with the pathogenesis of autism. These findings suggest that bee pollen and probiotics could be a beneficial therapeutic intervention for relieving the neurotoxic effects of propionic acid.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
