Antitumoral compounds from vertebrate sister group: A review of Mediterranean ascidians
2020
Among the diseases that afflict the human population, cancer is one for which many drug treatments are not yet known or effective. Moreover, the pharmacological treatments used often create serious side effects in sick patients and for this reason, it is essential to find effective and less harmful treatments. To date, marine biodiversity is a real source of metabolites with antitumoral activity and among invertebrates' ascidians have been the main source to obtain them. Mediterranean area is the richest in biodiversity and contains several ascidian species used in drugs development during the years. However, many more Mediterranean ascidian species have not been studied and could be a sour…
Pharmaceuticals and personal care products in a Mediterranean coastal wetland: Impact of anthropogenic and spatial factors and environmental risk ass…
2021
The present study focused on the occurrence, distribution and risk assessment of 32 pharmaceuticals and personal care products (PPCPs) in water and sediment, as well as the surrounding soil of the irrigation channels and lake of a Mediterranean coastal wetland, the Albufera Natural Park (Valencia, Spain). Moreover, the influent and effluent of ten wastewater treatment plants (WWTPs) that treat wastewater from Valencia and the surrounding areas were also studied. BPA, caffeine, diclofenac, ethyl paraben, methyl paraben, metformin, tramadol and salicylic acid were the predominant PPCPs detected in the channels and the lake, and are in good agreement with those detected in the effluent. Furthe…
Intensity of Italy's agri-food trade with countries outside the EU Mediterranean
2013
This paper aims to present a framework of trade relations between Italy and the countries of southern and eastern shores of the Mediterranean Sea. More specifically, using the indicators proposed in the analysis of international trade, we want to analyse the intensity of trade in agri-food products and the strength of trade ties between the bordering Mediterranean countries. The analysis of the intensity of trade flows of food products from Italy and the partner countries of North Africa and the Near East has allowed us to trace a network of flows between the countries in the area. If we can see an overall weakening of the agri-food trade, the analysis for individual partner states, however…
Dataset of pharmaceuticals and personal care products in a Mediterranean coastal wetland
2021
The dataset provides information on Pharmaceutical and Personal Care Products (PPCPs) detected in the Albufera Natural Park (Valencia, Spain), a typical Mediterranean coastal wetland. These PPCPs constitute an important group of organic pollutants highly representative of the human impact. The concentrations values measured in soil, sediment and water and the statistical relationship of contaminants between them and with the environmental parameters could help to understand their fate in different compartments. The data also reported the occurrence and removal efficiency (%) for each contaminant in ten wastewater treatment plants (WWTPs), located in the surrounding area. This dataset could …
Consumption of spices and ethnic contamination in the daily diet of Italians - consumers’ preferences and modification of eating habits
2021
AbstractCurrently, consumers appear to have diversified characteristics with regard to food tastes and consumption habits. The globalization of markets and the migration phenomenon contributed to the modification of food preferences of consumers who gradually introduce into their eating habits foods and recipes typical of the tradition of foreign countries. In this scenario, also in Italy, it is going to increase the use of “foreign products” with the consequent fusion of traditional cuisine techniques and recipes with ingredients that are typical of foreign countries and cultures. Foods and ingredients originally consumed in Asian or South American countries are increasingly consumed by It…
MAPs in Sicily: cultivation, uses, and potentiality
2013
In Sicily, MAPs have been used and cultivated for centuries, with many uses ranging from the preparation of fresh or stored food items, flavoring of foods and beverages, home-made human or animal therapy or even aesthetical purposes. Many of them grow spontaneously into such areas, and are claimed to play a significant role inside land biodiversity. The widespread belief that only under “natural” conditions MAPs find their optimum quality features has driven in many cases to their uncontrolled collection from the wild, and as a result many of them are nowadays at a risk of extinction. The field cropping of such spontaneous species could play an important role in safeguarding biodiversity, a…
Performance of industrial scale hollow-fibre membranes in a submerged anaerobic MBR (HF-SAnMBR) system at mesophilic and psychrophilic conditions
2013
The aim of this work was to evaluate the effect of temperature on the performance of industrial hollow-fibre (HF) membranes treating urban wastewater in a submerged anaerobic MBR system (SAnMBR). To this end, a demonstration plant with two commercial HF ultrafiltration membrane modules (PURON®, Koch Membrane Systems, PUR-PSH31) was operated at 20, 25 and 33 °C. The mixed liquor total solid (MLTS) level was a key factor affecting membrane permeability (K). K was higher under psychrophilic than mesophilic conditions when operating at similar transmembrane fluxes and MLTS, because the biomass activity of the psychrophilic mixed liquor was lower than the mesophilic mixed liquor. Thus, lower ext…
Functional characterization of Tat protein from human immunodeficiency virus. Evidence that Tat links viral RNAs to nuclear matrix.
1990
The processes of transcription and posttranscription are assumed to proceed in close association with the nuclear matrix. In this study we demonstrated that Tat, the trans-activating protein from human immunodeficiency virus type 1 (HIV-1), binds both to the TAR region of the nascent HIV mRNAs and the nuclear matrix with high affinity. Both North/Western blotting experiments and nitrocellulose binding studies revealed that Tat binds with an association constant (K alpha) of approximately 1 x 10(9) M-1 to the TAR segment of HIV RNA; binding of Tat to this sequence which is present between position 32 and 82 downstream from the TATA box was also confirmed by gel retardation assays. Binding of…
Microbial communities of the Mediterranean rocky shore: ecology and biotechnological potential of the sea‐land transition
2019
Microbial communities from harsh environments hold great promise as sources of biotechnologically relevant strains and compounds. In the present work, we have characterized the microorganisms from the supralittoral and splash zone in three different rocky locations of the Western Mediterranean coast, a tough environment characterized by high levels of irradiation and large temperature and salinity fluctuations. We have retrieved a complete view of the ecology and functional aspects of these communities and assessed the biotechnological potential of the cultivable microorganisms. All three locations displayed very similar taxonomic profiles, with the genus Rubrobacter and the families Xenoco…
Listeria spp. in Street-Vended Ready-to-Eat Foods.
2011
Street-vended ready-to-eat food sold in Egypt, including sandwiches and dishes of traditional food, was examined for the presence ofListeriaspecies. Out of 576 samples, 24% were found to containListeriaspecies.L. monocytogenesandL. innocuawere isolated from 57% and 39% of the contaminated samples, respectively. OtherListeriaspp. were detected with lower frequency.L. monocytogenesof ≥103 CFU/g were detected in 7% of the total examined samples, which represent 49% of the contaminated food samples (meat, poultry, seafood, dairy products, and products of plant origin). Most of the samples contaminated byL. monocytogeneshad high levels of total viable bacterial counts. The results obtained may h…
