Marine Invertebrates as Bioindicators of Heavy Metal Pollution

2015

The marine environment presents a range of anthropogenic contaminants. According to the World Health Organization, more than 100,000 chemicals are released into the global environment every year as a consequence of their production, use and disposal. The fate of a chemical substance depends on physical-chemical properties, in combination with the characteristics of the environment where it is released. Among the substances that accumulate in the sea, for anthropogenic activities, metals/metalloids have a leading position. Some of these have a biological role but their bioaccumulation is injurious. Chemical pollutants can cause effects on organisms, biodiversity and human health. Various eff…

Co-culture of rat brain cells as a tool for studying cell-cell interactions

2012

Brain capillary endothelial cells (BCECs) form the blood-brain barrier (BBB) in response to interaction with other brain cells (astrocytes, pericytes and neurons). BCECs are characterized by tight junctions (TJ), maturation and stabilization of which require different proteins, such as occludin. When co-cultured with astrocytes and neurons, BCECs were found to form a monolayer resembling the natural BBB: paracellular flux of dopamine and sucrose (i.e. compounds which are unable to cross the BBB in vivo) significantly decreased (1), while the transendothelial electrical resistance (TEER) increased. In these conditions, BCECs produced a larger amount of occludin and tended to localize it at t…

HPLC/HRMS and GC/MS for Triacylglycerols Characterization of Tuna Fish Oils Obtained from Green Extraction

2023

Background: Fish oil is one of the most common lipidic substances that is consumed as a dietary supplement. The high omega-3 fatty acid content in fish oil is responsible for its numerous health benefits. Fish species such as mackerel, herring, tuna, and salmon are particularly rich in these lipids, which contain two essential omega-3 fatty acids, known as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Objectives: Due to the scarcity of information in the literature, this study aimed to conduct a qualitative and quantitative characterization of triglycerides (TAGs) in crude tuna fish oil using HPLC/HRMS. Fatty acid (FA) determination was also performed using GC/MS. The tuna fis…

BROILER CHICKENS AND THEIR HEALTH STATUS IN FARM: WINE WASTE, AN ADDED VALUE ON FEEDING

2023

Various key economic sectors of the National and Sicilian economy, in addition to contributing to the economic growth also cause a considerable production of waste which today are a problem both for companies then for the environment. For this reason, there is considerable interest in this waste and in the possibility of their reuse to extract bioactive molecules with added value, all in accordance with the objectives of the Blue Economy. In this regard, it has already been demonstrated that from the production waste of various economic sectors it is possible to obtain bioactive molecules with anticancer, antimicrobial, cosmetic, antioxidant and nutraceutical properties (Mauro et al., 2022)…

The Use of Stable Isotope Ratio Analysis to Trace European Sea Bass (D. labrax) Originating from Different Farming Systems

2020

This study aimed to determine whether isotopic ratio mass spectrometry (IRMS) can discriminate farmed European sea bass according to different farming systems and geographic origins. Dicentrarchus labrax of commercial size from three different rearing systems (concrete tank inland, sea cages, and extensive methods in valleys or salt works) were collected at the trading period (autumn&ndash
