The effect of omega-3 long chain polyunsaturated fatty acids on aggressive behaviour in adult male prisoners: a structured study protocol for a multi-centre, double-blind, randomised placebo-controlled trial and translation into policy and practice.

Background: Interventions to better manage aggressive behaviour and reduce recidivism are a primary concern for corrective services. Nutritional interventions to correct prisoner behaviour have been largely overlooked in the literature. Emerging evidence suggests that dietary intake influences aggressive behaviours and that nutritional supplementation with omega-3 long chain polyunsaturated fatty acids (n-3 LCPUFA) could attenuate both the severity and frequency of aggressive behaviour.

3D bioprinting dermal-like structures using species-specific ulvan.

3D bioprinting has been increasingly employed in skin tissue engineering for manufacturing living constructs with three-dimensional spatial precision and controlled architecture. There is however, a bottleneck in the tunability of bioinks to address specific biocompatibility challenges, functional traits and printability. Here we report on a traditional gelatin methacryloyl (GelMA) based bioink, tuned by addition of an ulvan type polysaccharide, isolated from a cultivated source of a specific Australian Ulvacean macroalgae (Ul84).

Development of rhamnose-rich hydrogels based on sulfated xylorhamno-uronic acid toward wound healing applications.

An array of biological properties is demonstrated in the category of extracts broadly known as ulvans, including antibacterial, anti-inflammatory and anti-coagulant activities. However, the development of this category in biomedical applications is limited due to high structural variability across species and a lack of consistent and scalable sources. In addition, the modification and formulation of these molecules is still in its infancy with regard to progressing to product development.

Fabrication and In Vitro Characterization of Electrochemically Compacted Collagen/Sulfated Xylorhamnoglycuronan Matrix for Wound Healing Applications.

Skin autografts are in great demand due to injuries and disease, but there are challenges using live tissue sources, and synthetic tissue is still in its infancy. In this study, an electrocompaction method was applied to fabricate the densely packed and highly ordered collagen/sulfated xylorhamnoglycuronan (SXRGlu) scaffold which closely mimicked the major structure and components in natural skin tissue. The fabricated electrocompacted collagen/SXRGlu matrices (ECLCU) were characterized in terms of micromorphology, mechanical property, water uptake ability and degradability.

Correction: Baseline Omega-3 Index Correlates with Aggressive and Attention Deficit Disorder Behaviours in Adult Prisoners.

Parameters affecting the analytical profile of fatty acids in the macroalgal genus Ulva.

The fatty acids (FA) of Ulva have potential to contribute to nutrition. However the large variability of FA profiles of Ulva species; thus the quality and quantity of FA in relation to nutrition is poorly defined. Herein we investigate the FA profile of 74 cultured Ulva samples crossing five culture regimes, six extraction regimes and four post-harvesting processes.

Applications of seaweed extracts in Australian agriculture: past, present and future.

A rapidly growing world population has highlighted the need to significantly increase food production in the context of a world with accelerating soil and water shortages as well as climatic stressors. This situation has generated new interest in the application of liquid seaweed extracts because of their potent plant growth-enhancing properties through metabolic benefits, triggering disease response pathways and increasing stress tolerance. The basis for these benefits is complex and poorly understood.

Baseline omega-3 index correlates with aggressive and attention deficit disorder behaviours in adult prisoners.

Background: There is emerging evidence that the supplementation of omega-3 contributes to a decrease in aggressive behaviour in prison populations. A challenge of such research is achieving statistical power against effect sizes which may be affected by the baseline omega-3 index. There are no published data on the blood omega-3 index with studies of this kind to assess the variability of the blood omega-3 index in conjunction with aggression and attention deficit assessments.
