Summary: From 2008 to 2018, a study analyzed a large number of clam and mussel samples collected along the Marche coast in Italy, showing that levels of lead, cadmium, vanadium, nickel, chromium, and arsenic in the shellfish were comparable to published standards, with mercury always below the detection limit. Lead and cadmium showed a decreasing trend in clams and remained relatively stable in mussels.

Summary: Study on the effects of exposure to trace metal mixtures in wild Mediterranean mussels revealed continuous increase in body burdens of Cu and Pb throughout the exposure period, while Zn accumulation reached a plateau after day 10 in the whole body and gills. Metabolomics analysis indicated that multiple metabolites were down-regulated and multiple metabolic pathways possibly interrupted by the exposure to the mixture of trace metals.

Summary: This study developed a novel biochar modification material alpha-AC@BC, which could transform -NO2 into -NH2 under electricity catalysis and form a special alpha-amino acid-like structure by combining with carboxyl groups. The alpha-AC@BC exhibited high removal efficiencies for copper, cadmium, lead, and zinc, even in acid soil with low pH. The adsorption-desorption cycles demonstrated its potential for practical application in heavy metal remediation.

Summary: Several international organisations have recommended the use of bioindicators to improve the evaluation of ecological risk in marine ecosystems. In this study, wild mussels were collected from thirty sampling points along the Asturias coastline and analyzed to identify the relationship between metal concentrations in mussel tissues and the geological and environmental conditions of the coastal area. The study revealed concentration trends for different metals and correlations between them. The mussels also showed natural defense against certain metals. Cluster analysis of the samples grouped them based on the sources of the metal concentrations. Both anthropic and natural sources have led to an increase in metal loads in mussels, sometimes exceeding international environmental criteria.

Summary: The increasing use of seaweeds in European cuisine has led to cultivation initiatives funded by the EU. Research shows that long-term cultivation of the sea lettuce Ulva lactuca produces consistently high-quality biomass with nutritional value, providing sufficient minerals for daily dietary intake while posing low health risks from heavy metals. The nutritional value of Ulva, in terms of carbohydrates, protein, and fatty acids, is comparable to selected fruits, vegetables, nuts, and grains.

Summary: The health condition of Mytilus galloprovincialis native to a polluted habitat was investigated before and after 30 and 60 days of in situ transplantation and in vivo experiments. The results showed a decrease in filtration rate by 24% and 45%, respectively, after 60 days of in vivo and in situ experiments compared to the rates at the polluted sites. The respiration rate reached a minimum of 0.081 ± 0.05 mg O2.L- 1 after 60 days of in situ transplantation. Additionally, antioxidant activities showed time-dependent changes for both transplantation conditions, with the highest activities declining by 76% and 54% for superoxide dismutase and catalase, respectively, after 60 days of in situ transplantation. Changes in lipid peroxidation and acetylcholinesterase activity were observed in internal organs following 60 days of transplantation. At this time slot, the lowest content of metals and microplastics was also noted.

Summary: The study aimed to investigate the behavior of Zygosaccharomyces rouxii, the main microorganism responsible for MBIC spoilage, and to inhibit its growth by selecting antimicrobial agents. It was found that only 2% v/v ethanol was effective in inhibiting the growth of Z. rouxii, while other antimicrobials tested were not able to stop yeast spoilage and changed the color and flavor of the products. Ethanol was recommended due to its extreme effectiveness against osmotolerant yeasts, and the treated MBICs remained stable until the end of their shelf-life.

Summary: Biostimulants are organic compounds that can influence the biochemical activity of plants. This study investigated the effect of foliar application of a biostimulant containing amino acids, peptides, and natural triacontanol on a woody perennial crop, the 'Ribolla Gialla' grapevine. The treated plants showed earlier ripening, veraison, and harvest, as well as higher enological parameters compared to the non-treated plants. Additionally, the biostimulant promoted the growth of the microbial community on the berry skin, which had a positive effect on must quality for winemaking.

Summary: The aim of this study was to investigate the effects of fasting and refeeding on body condition, gut physiology, and microbiota in reared rainbow trout. The results showed that fasting and refeeding had significant effects on the fish's weight, visceral condition, and liver condition, as well as the gut microbiota. Feed deprivation led to dysbiosis in the gut microbiota, but these effects were gradually mitigated by refeeding.

Summary: The aim of this study was to investigate the microbial and physico-chemical characteristics of cold smoked sea bass (CSSB), a novel italian fish product. The results showed the presence of bacterial contamination from raw materials, the environment, and the production process. High levels of lactic acid bacteria (LAB) and total bacteria count (TBC) were observed during storage, but did not significantly affect the total volatile basic nitrogen (TVB-N). Pathogenic bacteria were not detected. Cold smoked sea bass offers high nutritional value and excellent microbial quality, making it a beneficial food source.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
