Effect of freezing/thawing process in different sizes of blue fish in the Mediterranean through lysosomal enzymatic tests
2014
The assessment of freshness of different sizes of blue fish (Engraulis encrasicolus 12 cm, Sardina pilchardus 15 cm, Trachurus trachurus 40 cm, Scomber japonicus colias 60 cm) was carried out using non-conventional enzymatic methods. The activities of the three lysosomal enzymes (α-glucosidase (AG), β-galactosidase (B-GAL) and β-N-acetylglucosamidase (B-NA)) in extracts of blue fish muscle were measured over a period of 21 days of storage. A significant increase (p < 0.05) of AG activity was observed in all species, with a large increase seen after only one day of storage. B-NA activity increased slightly in sardines, horse mackerels and chub mackerel during frozen/thawed storage. Finally, …
Chemical-physical and nutritional characteristics of mature-green and mature-ripe ‘Kensington Pride’ mango fruit cultivated in Mediterranean area dur…
2017
Introduction - Mango is a very short postharvest life climacteric fruit. Mangoes are usually harvested firm and green because they are often assigned to long transportation before reaching the market, or they are collected after color break for local markets. In both cases, temperature control is the most critical factor in fruit ripening management. The aim of this study was to investigate the quality evolution of mature-green and mature-ripe mango fruit submitted to 8°C and 90 ± 5% of relative humidity to assess the possibility to prolong its postharvest life. Materials and methods - The fruit of mango (Mangifera indica L. cv. Kensington Pride) grown in a Mediterranean environment was s…
Selenium bio-enrichment of Mediterranean fruit juices through lactic acid fermentation.
2021
Abstract This work was carried out to elaborate selenium (Se) bio-enriched fermented Mediterranean fruit juices. To this purpose, pomegranate and table red grape juices were added with sodium selenite (Na2SeO3) and fermented by Levilactobacillus brevis CRL 2051 and Fructobacillus tropaeoli CRL 2034 individually or combined. To better evaluate the effect of selenite addition and starter strain inoculums on the total bacterial community of the fruit juices, fermentation trials were performed with raw and pasteurized fruit juices. No statistical significant differences were observed for total mesophilic microorganisms (TMM) and rod-shaped lactic acid bacteria (LAB) levels among raw and pasteur…
Migrant Women-experiences from the Mediterranean Region
2019
Introduction: The phenomenon of migration is characterized and influenced by a number of different variables; and the different stages of journey are related to different levels and types of psychological distress. Women, in particular, are exposed to further specific risks during migration. Aim: To determine the factors that affect the psychological health of migrant women during the different stages of the migration journey. Methods: We provide a narrative review of the literature around the experiences of women during migration process, with a geographical focus on women migrating to the Mediterranean area. Results: Little data is currently available on the burden of mental health disor…
Using genetic markers to unravel the origin of birds converging towards pre-migratory sites
2018
AbstractIdentifying patterns of individual movements in spatial and temporal scales can provide valuable insight into the structure of populations and the dynamics of communities and ecosystems. Especially for migrating birds, that can face a variety of unfavorable conditions along their journey, resolving movements of individuals across their annual cycle is necessary in order to design better targeted conservation strategies. Here, we studied the movements of a small migratory falcon, the Lesser Kestrel (Falco naumanni), by genetically assigning feathers from individuals of unknown origin that concentrate in large roosts during the pre-migratory period. Our findings suggest that birds fro…
Candidate Gene and Genome-Wide Association Studies for Circulating Leptin Levels Reveal Population and Sex-Specific Associations in High Cardiovascul…
2019
Leptin is a hormone crucial in the regulation of food intake and body-weight maintenance. However, the genes and gene variants that influence its plasma levels are still not well known. Results of studies investigating polymorphisms in candidate genes have been inconsistent, and, in addition, very few genome-wide association studies (GWAS) have been undertaken. Our aim was to investigate the genes and gene variants most associated with plasma leptin concentrations in a high-cardiovascular-risk Mediterranean population. We measured plasma leptin in 1011 men and women, and analyzed the genetic factors associated using three approaches: (1) Analyzing the single nucleotide polymorphisms (SNPs) …
Data for nine autosomal STRs markers from Valencia (East Mediterranean coast of the Iberian Peninsula)
2000
Nine STRs loci have been typed in a sample from Valencia, a population from the East Mediterranean coast of the Iberian Peninsula.
The STR252-IVS10nt546-VNTR7 phenylalanine hydroxylase minihaplotype in five Mediterranean samples.
1997
IVS10nt546 (IVS10nt-11g→a) is the most common molecular defect of the phenylalanine hydroxylase gene causing phenylketonuria in Mediterranean populations. Previous studies have proposed various and alternative hypotheses concerning the geographical origin and pattern of diffusion of this mutation in this area. In this study, this issue was re-examined on a large sample (149) of “Mediterranean” IVS10nt546 mutant alleles analysed with multiallelic intragenic polymorphisms. The analysis of intragenic microsatellite (STR) and minisatellite (VNTR) polymorphisms shows allelic heterogeneity of the IVS10nt546 mutation. Eight STR and three VNTR alleles were found in association with the splicing def…
Atmospheric risks and climate change: didactic proposals for the Mediterranean region in middle and high school
2021
La educación es una acción fundamental para reducir la acción de los riesgos naturales dentro del contexto del cambio climático actual. No obstante, en los países desarrollados no ha tenido un protagonismo destacado en cuanto al diseño de las políticas de prevención de estos riesgos. Y ello, a pesar del papel que cubre en la concienciación que puedan lograr las cohortes más jóvenes de la sociedad ya que serán protagonistas de estos procesos en las próximas décadas. Este trabajo tiene por objeto proponer actividades didácticas para el tratamiento de cinco procesos principales de manifestación extrema del clima que ya afectan a la región mediterránea y que deben incorporarse en la asignatura …
Seed germination and reproductive features of Lysimachia minoricensis (Primulaceae), a wild-extinct plant.
2002
Lysimachia minoricensis is one of the few Mediterranean endemic plants (Minorca, Balearic islands) that has gone extinct in the wild but which persists as extant germplasm or cultivated plants in several botanical gardens. Reproductive features (seed set, number of seeds per capsule, seed weight) and germination responses to constant temperatures, sea water and dry-heat pre-treatments were investigated to determine the extent to which they may have influenced the extinction of the species. Seed set in Lysimachia is not dependent on pollinators, suggesting a functional selfer breeding system. Most plants produced a large mean number of fruits (23.2) and seeds (466), and the mean production o…
