Opportunities and challenges in upcycling agri-food byproducts to generate insect manure (frass): A literature review.

A range of issues related to sustainability in the agrifood industry have spurred interest in mass production of insects as human food and animal feed alternatives. This rapidly evolving sector addresses several challenges, including the management of food waste or agrifood by-products and the production of alternative animal proteins demonstrating low environmental impacts that improve sector circularity. The mass production of insects on agrifood processing wastes or by-products represents an opportunity to address these challenges.

Characterization of hatchery residues for on farm implementation of circular waste management practices.

The conventional management of hatchery residues is associated with greenhouse gas and unpleasant odor emissions, the presence of pathogens and high disposal costs for producers. To address these issues, on-farm alternatives like composting, fermentation, and insect valorization are promising approaches. This study aims to characterize hatchery residues and define critical quality thresholds to identify effective processes for their management.

"I Can't Take off My Shirt or Do My Own Hair"-A Qualitative Investigation of the Symptoms and Impact Experience of Children and Adolescents with Fibrodysplasia Ossificans Progressiva (FOP).

Introduction: Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare, severely disabling, autosomal dominant, congenital disease characterized by progressive multi-focal heterotopic ossification (HO) of skeletal muscle, ligaments, tendons, and fascia. Past FOP studies have focused on the clinical aspects of the disease; therefore, there is a paucity of qualitative research on the patient experience. Our objective was to better understand the experience of children and adolescents living with FOP from their and their parents' perspectives.

Mitochondrial bioenergetics of astrocytes in Fragile X syndrome: new perspectives on culture conditions and sex effects.

Fragile X syndrome (FXS) is a genetic disorder that is characterized by a range of cognitive and behavioral deficits, including mild-moderate intellectual disability. The disease is characterized by an X-linked mutation of the gene, which causes silencing of the gene coding for fragile X mental retardation protein (FMRP), a translational regulator integral for neurodevelopment. Mitochondrial dysfunction has been recently associated with FXS, with reports of increases in oxidative stress markers, reactive oxygen species, and lipid peroxidation being present in the brain tissue.

Objective: To examine the relationships between the following: (1) patient demographics, patient-provider discussions, and health-related goal setting and achievement, and (2) patient mobile health app use and goal achievement.

Astrocyte-mediated disruption of ROS homeostasis in Fragile X mouse model.

Astrocytes, glial cells within the brain, work to protect neurons during high levels of activity by maintaining oxidative homeostasis via regulation of energy supply and antioxidant systems. In recent years, mitochondrial dysfunction has been highlighted as an underlying factor of pathology in many neurological disorders. In animal studies of Fragile X Syndrome (FXS), the leading genetic cause of autism, higher levels of reactive oxygen species, lipid peroxidation, and protein oxidation within the brain indicates that mitochondria function is also altered in FXS.

Apparent Digestibility of Macronutrients and Fatty Acids from Microalgae ( sp.) Fed to Rainbow Trout (): A Potential Candidate for Fish Oil Substitution.

Aquaculture feed formulation has recently turned its focus to reduce the reliance on marine-derived resources and utilise alternative feedstuffs, as an approach to improve the environmental sustainability of the aquaculture sector. The fish oil market is highly volatile, and availability of this commodity is continuously decreasing for use in aquaculture. Currently, a growing number of commercial efforts producing microalgae are providing omega 3-rich oil for sustainable aquaculture feed.

Thermal tolerance and fish heart integrity: fatty acids profiles as predictors of species resilience.

The cardiovascular system is a major limiting system in thermal adaptation, but the exact physiological mechanisms underlying responses to thermal stress are still not completely understood. Recent studies have uncovered the possible role of reactive oxygen species production rates of heart mitochondria in determining species' upper thermal limits. The present study examines the relationship between individual response to a thermal challenge test (CT), susceptibility to peroxidation of membrane lipids, heart fatty acid profiles and cardiac antioxidant enzyme activities in two salmonid species from different thermal habitats (, ) and their hybrids.

Hybridization between char species ( and ): a fast track for novel allometric trajectories.

Hybridization between closely related species can generate genetic and phenotypic variation, providing valuable biological material to assess the physiological impact of the structural or functional variability of different organs. In the present study, we examined growth rates of various organs and whole body in brook char, Arctic char and their reciprocal hybrids over a period of 281 days. Parental species achieved significantly higher body mass than their hybrids.

Thermal tolerance and thermal sensitivity of heart mitochondria: Mitochondrial integrity and ROS production.

Cardiac mitochondrial metabolism provides 90% of the ATP necessary for the contractile exertion of the heart muscle. Mitochondria are therefore assumed to play a pivotal role in heart failure (HF), cardiovascular disease and ageing. Heat stress increases energy metabolism and oxygen demand in tissues throughout the body and imposes a major challenge on the heart, which is suspected of being the first organ to fail during heat stress.

Establishment of a comprehensive reference transcriptome for vertebral bone tissue to study the impacts of nutritional phosphorus deficiency in rainbow trout (Oncorhynchus mykiss, Walbaum).

Reducing dietary phosphorus (P) is a common approach to reduce effluent P outputs. The potential resulting P-deficiency is known to negatively impact fish bone condition and might result in vertebral deformities. To date, no large-scale study involving deep sequencing of the bone transcriptome has been conducted in salmonids and vertebral molecular changes remain poorly described.

In vivo solid-phase microextraction with in vitro calibration: determination of off-flavor components in live fish.

The presence of off-flavor compounds in fish represents a significant economic problem encountered in aquaculture production. The off-flavor compounds are due to the absorption of substances produced by a range of microorganisms. Currently, a number of strategies have been used to prevent or limit the growth of these microorganisms.

Impact of water quality on the bacterial populations and off-flavours in recirculating aquaculture systems.

A variety of factors affecting water quality in recirculating aquaculture systems (RAS) are associated with the occurrence of off-flavours. In this study, we report the impact of water quality on the bacterial diversity and the occurrence of the geosmin-synthesis gene (geoA) in two RAS units operated for 252 days. Unit 2 displayed a higher level of turbidity and phosphate, which affected the fresh water quality compared with unit 1.

Influences of dietary biotin and avidin on growth, survival, deficiency syndrome and hepatic gene expression of juvenile Nile tilapia Oreochromis niloticus.

This study was undertaken to assess the interactive effects of dietary biotin and avidin on growth, feed conversion, survival and deficiency syndrome of tilapia and to determine the influence of dietary biotin deficiency on the expression of key genes related to biotin metabolism in tilapia. Six iso-nitrogenous and iso-energetic diets based on a common purified basal diet (vitamin-free casein as the protein source) were prepared for this study. The six dietary groups were 0 g avidin with 0 mg biotin (A0B0), 0 g avidin with 0.

Establishment of a real-time PCR method for quantification of geosmin-producing Streptomyces spp. in recirculating aquaculture systems.

Geosmin and 2-methylisoborneol (MIB) have been associated with off-flavour problems in fish and seafood products, generating a strong negative impact for aquaculture industries. Although most of the producers of geosmin and MIB have been identified as Streptomyces species or cyanobacteria, Streptomyces spp. are thought to be responsible for the synthesis of these compounds in indoor recirculating aquaculture systems (RAS).

Preliminary evidence of the contribution of the intestinal microflora to biotin supply in zebrafish Danio rerio (Hamilton-Buchanan).

A study was conducted to preliminarily assess the contribution of the intestinal microflora to biotin supply in zebrafish. Biotin and avidin were added to three isonitrogenous and isocaloric purified diets to provide molar avidin: biotin ratios of 0:0 (basal diet), 0:1 (biotin-supplemented diet), and 120:0. Another diet was made by supplementing the antibiotic succinylsulfathiazole (1%, wt/wt) to the basal diet.
