Widespread asymmetries of amygdala nuclei predict auditory verbal hallucinations in schizophrenia.

Background: Auditory verbal hallucinations, which frequently involve negative emotions, are reliable symptoms of schizophrenia. Brain asymmetries have also been linked to the condition, but the relevance of asymmetries within the amygdala, which coordinates all emotional signals, to the content of and response to auditory verbal hallucinations has not been explored.

Methods: We evaluated the performance of two asymmetry biomarkers that were recently introduced in literature: the distance index, which captures global asymmetries, and a revised version of the laterality index, which captures left-right local asymmetries.

Brain asymmetry is globally different in males and females: exploring cortical volume, area, thickness, and mean curvature.

Brain asymmetry is a cornerstone in the development of higher-level cognition, but it is unclear whether and how it differs in males and females. Asymmetry has been investigated using the laterality index, which compares homologous regions as pairwise weighted differences between the left and the right hemisphere. However, if asymmetry differences between males and females are global instead of pairwise, involving proportions between multiple brain areas, novel methodological tools are needed to evaluate them.

Synthesis, Physicochemical Characteristics, and Biocompatibility of Multi-Component Collagen-Based Hydrogels Developed by E-Beam Irradiation.

Herein, three different recipes of multi-component hydrogels were synthesized by e-beam irradiation. These hydrogels were obtained from aqueous polymer mixtures in which different proportions of bovine collagen gel, sodium carboxymethylcellulose (CMC), poly(vinylpyrrolidone), chitosan, and poly(ethylene oxide) were used. The cross-linking reaction was carried out exclusively by e-beam cross-linking at 25 kGy, a dose of irradiation sufficient both to complete the cross-linking reaction and effective for hydrogel sterilization.
