Stability and expression patterns of housekeeping genes in Mediterranean mussels (Mytilus galloprovincialis) under field investigations.

The use of marine mussels as biological models encompasses a broad range of research fields, in which the application of RNA analyses disclosed novel biomarkers of environmental stress and investigated biochemical mechanisms of action. Quantitative real-time PCR (qPCR) is the gold standard for these studies, and despite its wide use and available protocols, it may be affected by technical flaws requiring reference gene data normalization. In this study, stability of housekeeping genes commonly employed as reference genes in qPCR analyses with Mytilus galloprovincialis was explored under field conditions.

The social value of place-based creative wellbeing: A rapid review and evidence synthesis.

Creative well-being is an increasing field of interest to which biomedical and social sciences have made uneven contributions. The instrumental value of culture and its subsequential public investment is grounded in the interplay of social, cultural and economic capital to attain and preserve wellbeing and health and foster social mobility. The current evidence addresses the effectiveness of arts interventions in improving illnesses.

What Works to Improve Wellbeing? A Rapid Systematic Review of 223 Interventions Evaluated with the Warwick-Edinburgh Mental Well-Being Scales.

Introduction: The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) is a commonly used scale of mental wellbeing focusing entirely on the positive aspect of mental health. It has been widely used in a broad range of clinical and research settings, including to evaluate if interventions, programmes or pilots improve wellbeing. We aimed to systematically review all interventions that used WEMWBS and evaluate which interventions are the most effective at improving wellbeing.

Variability of metabolic, protective, antioxidant, and lysosomal gene transcriptional profiles and microbiota composition of Mytilus galloprovincialis farmed in the North Adriatic Sea (Italy).

This study evaluates the transcriptional profiles of genes related to physiological responses in digestive glands (DG) of Mytilus galloprovincialis under the influence of seasonal changes of environmental variables, gender bias, and gonadal development. Composition of the DG microbiome was also explored. Mussels were collected across 7 months encompassing 3 seasons from a farm in the Northwestern Adriatic Sea.

Impact of Marine Aquaculture on the Microbiome Associated with Nearby Holobionts: The Case of Living in Proximity of Sea Bream Aquaculture Cages.

Aquaculture plays a major role in the coastal economy of the Mediterranean Sea. This raises the issue of the impact of fish cages on the surrounding environment. Here, we explore the impact of aquaculture on the composition of the digestive gland microbiome of a representative locally dwelling wild holobiont, the grazer gastropod , at an aquaculture facility located in Southern Sicily, Italy.

Tissue-scale microbiota of the Mediterranean mussel (Mytilus galloprovincialis) and its relationship with the environment.

In this study, we characterize the structural variation of the microbiota of Mytilus galloprovincialis at the tissue scale, also exploring the connection with the microbial ecosystem of the surrounding water. Mussels were sampled within a farm located in the North-Western Adriatic Sea and microbiota composition was analyzed in gills, hemolymph, digestive glands, stomach and foot by Next Generation Sequencing marker gene approach. Mussels showed a distinctive microbiota structure, with specific declinations at the tissue level.

Role of nutrient concentrations and water movement on diatom's productivity in culture.

Microalgal growth maximization is becoming a duty for enhancing the biotechnological fate of these photosynthetic microorganisms. This study, based on an extensive set of data, aims to revisit diatom's cultivation in laboratory with the objective to increase growth rate and biomass production. We investigated the growth ability and resource requirements of the coastal diatom Skeletonema marinoi Sarno & Zingone grown in laboratory in the conventional f/2 medium with aeration and in two modified conditions: (i) the same medium with water movement inside and (ii) an enriched medium with the same water movement.

Impact of non-LTR retrotransposons in the differentiation and evolution of anatomically modern humans.

Background: Transposable elements are biologically important components of eukaryote genomes. In particular, non-LTR retrotransposons (N-LTRrs) played a key role in shaping the human genome throughout evolution. In this study, we compared retrotransposon insertions differentially present in the genomes of Anatomically Modern Humans, Neanderthals, Denisovans and Chimpanzees, in order to assess the possible impact of retrotransposition in the differentiation of the human lineage.
