Use of mass spectrometry to determine the diversity of toxins produced by gambierdiscus and fukuyoa species from Balearic Islands and Crete (Mediterranean Sea) and the Canary Islands (Northeast Atlantic)

Over the last decade, knowledge has significantly increased on the taxonomic identity and distribution of dinoflagellates of the genera Gambierdiscus and Fukuyoa. Additionally, a number of hitherto unknown bioactive metabolites have been described, while the role of these compounds in ciguatera poisoning (CP) remains to be clarified. Ciguatoxins and maitotoxins are very toxic compounds produced by

A hyperpromiscuous antitoxin protein domain for the neutralization of diverse toxin domains

Toxin-antitoxin (TA) gene pairs are ubiquitous in microbial chromosomal genomes and plasmids as well as temperate bacteriophages. They act as regulatory switches, with the toxin limiting the growth of bacteria and archaea by compromising diverse essential cellular targets and the antitoxin counteracting the toxic effect. To uncover previously uncharted TA diversity across microbes and bacteriophag

Engagement of stakeholders in action-oriented education for sustainability: a study of motivations and benefits and development of a process model

PurposeEngagement of non-academic stakeholders is an important element of education for sustainability, but is rarely mentioned in contemporary agricultural education literature. This article investigates the process of engagement of non-academic stakeholders into higher education programs on agriculture. Non-academic stakeholders refer to private firms that are focused on the acquisition of knowl

A multi-level resource circularity index based in the European Union’s circular economy monitoring framework

Purpose: to propose two enhancements for the European Union’s Circular Material Use rate (CMU): inclusion of Preparation for Reuse (PfR) flows and enhanced reproducibility across lower levels of analysis. Methods: PfR flows are added to the material flow Sankey Diagram. The Local Circularity Rate (LCR) is based in the CMU and is broke down in three waste-related ratios: recovered-to-treated (RCV-t

Reconciling the Greenland ice-core and radiocarbon timescales through the Laschamp geomagnetic excursion

Cosmogenic radionuclides, such as 10Be and 14C, share a common production signal, with their formation in the Earth's upper atmosphere modulated by changes to the geomagnetic field, as well as variations in the intensity of the solar wind. Here, we use this common production signal to compare between the radiocarbon (IntCal)and Greenland ice-core (GICC05)timescales, utilising the most pronounced c

Impact of the COVID-19 “Lockdown” on Air Quality in Athens

This thesis examined the impact of the COVID-19 lockdown on Athenian air quality from March 23rd to May 5th, 2020. The Attica Ground Measuring Network was used to measure the concentrations of NO, NO₂, SO₂, CO, PM₁₀, PM₂.₅, and O₃ for the 2020 lockdown and for the same time period from 2005 to 2019 as reference. Nitric oxide (NO) and nitrogen dioxide (NO₂) concentrations decreased by up to 75% an

Waste Management on Islands

In the last three decades insular areas are in continuous research because their unique characteristics indicate them as “ideal laboratories” for the application of different systems. Waste management systems in particular, are considered to be among the most intriguing of issues, because of insular specificities, such as remoteness, level of insularity (possibility of double or multiple insularit

Consumption of dairy products in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort: data from 35955 24-hour dietary recalls in 10 European countries

Objectives: To describe and compare the consumption of dairy products in cohorts included in the European Prospective Investigation into-Cancer and Nutrition (EPIC). Methods: Data from single 24-hour dietary recall interviews collected through a highly standardised computer-based program (EPIC-SOFT) in 27 redefined centres in 10 European countries between 1995 and 2000. From a total random sample

Dietary glycaemic index and glycaemic load in the European Prospective Investigation into Cancer and Nutrition

Objectives: To describe dietary glycaemic index (GI) and glycaemic load (GL) values in the population participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study according to food groups, nutrients and lifestyle characteristics. Methods: Single 24-h dietary recalls (24-HDRs) from 33 566 subjects were used to calculate dietary GI and GL, and an ad hoc database was

Region-Specific Nutrient Intake Patterns Exhibit a Geographical Gradient within and between European Countries

Until recently, the study of nutrient patterns was hampered at an international level by a lack of standardization of both dietary methods and nutrient databases. We aimed to describe the diversity of nutrient patterns in the European Prospective Investigation into Cancer and Nutrition (EPIC) study at population level as a starting point for future nutrient pattern analyses and their associations

Vicariance divergence and gene flow among islet populations of an endemic lizard.

Allopatry and allopatric speciation can arise through two different mechanisms: vicariance or colonization through dispersal. Distinguishing between these different allopatric mechanisms is difficult and one of the major challenges in biogeographical research. Here, we address whether allopatric isolation in an endemic island lizard is the result of vicariance or dispersal. We estimated the amount

Office building refurbishment based on assesment of energy and natural resource conservation

When the replacement of an existing building by a new one is financially restrictive or not possible for any reason, refurbishment can be the only option. The refurbishment of a non-residential building may require a specialized study, not only because of building location, use, importance and historic significance, but also because it provides the opportunity to take measures to reduce energy con

Solution structures of human and porcine beta-microseminoprotein

beta-Microseminoprotein (MSP) is a small cysteine-rich protein (molecular mass about 10 kDa) first isolated from human seminal plasma and later identified in several other organisms. The function of MSP is not known, but a recent study has shown MSP to bind CRISP-3, a protein present in neutrophilic granulocytes. The amino acid sequence is highly variable between species raising the question of th

Dietary intakes and food sources of phenolic acids in the European Prospective Investigation into Cancer and Nutrition (EPIC) study

Phenolic acids are secondary plant metabolites that may have protective effects against oxidative stress, inflammation and cancer in experimental studies. To date, limited data exist on the quantitative intake of phenolic acids. We estimated the intake of phenolic acids and their food sources and associated lifestyle factors in the European Prospective Investigation into Cancer and Nutrition (EPIC

International variations in hip fracture probabilities: Implications for risk assessment

It is recommended that intervention thresholds should be based on absolute fracture risk, but there is a large variation in hip fracture incidence from different regions of the world. The aim of this study was to examine heterogeneity of hip fracture probability in different regions from recent estimates of hip fracture incidence and mortality to adjust intervention thresholds. Ten-year probabilit

Localizing Ashkenazic Jews to Primeval Villages in the Ancient Iranian Lands of Ashkenaz

The Yiddish language is over 1,000 years old and incorporates German, Slavic, and Hebrew elements. The prevalent view claims Yiddish has a German origin, whereas the opposing view posits a Slavic origin with strong Iranian and weak Turkic substrata. One of the major difficulties in deciding between these hypotheses is the unknown geographical origin of Yiddish speaking Ashkenazic Jews (AJs). An an

Needs, barriers and facilitators for a healthier lifestyle in haemodialysis patients : The GoodRENal project

Background: Malnutrition, sedentary lifestyle, cognitive dysfunction and poor psychological well-being are often reported in patients on haemodialysis (HD). Aims: We aimed to explore needs, barriers and facilitators—as perceived by patients, their carers, and healthcare professionals (HCPs) for increasing the adherence to the diet, to physical activity and cognition and psychological well-being.
