Cardiotoxicity and Cardioprotection by Artesunate in Larval Zebrafish
2019
Although artesunate (ART) is generally accepted as a safe and well-tolerated first-line treatment of severe malaria, cases of severe side effects and toxicity of this compound are also documented. This study applied larval zebrafishes to determine the acute toxicity and efficacy of ART and performed RNA-sequencing analyses to unravel the underlying signaling pathways contributing to ART’s activities. Results from acute toxicity assay showed that a single-dose intravenous injection of ART from 3.6 ng/fish (1/9 maximum nonlethal concentration) to 41.8 ng/fish (lethal dose 10%) obviously induced pericardial edema, circulation defects, yolk sac absorption delay, renal edema, and swim bladder l…
Current concepts in the prevention of pathogen transmission via blood/plasma-derived products for bleeding disorders
2015
The pathogen safety of blood/plasma-derived products has historically been a subject of significant concern to the medical community, Measures such as donor selection and blood screening have contributed to increase the safety of these products, but pathogen transmission does still occur. Reasons for this include lack of sensitivity/specificity of current screening methods, lack of reliable screening tests for some pathogens (e.g. prions) and the fact that many potentially harmful infectious agents are not routinely screened for. Methods for the purification/inactivation of blood/plasma-derived products have been developed in order to further reduce the residual risk, but low concentrations…
Effects of Infant Formula With Human Milk Oligosaccharides on Growth and Morbidity: A Randomized Multicenter Trial
2017
Objectives:The aim of the study was to evaluate the effects of infant formula supplemented with 2 human milk oligosaccharides (HMOs) on infant growth, tolerance, and morbidity. Methods:Healthy infants, 0 to 14 days old, were randomized to an intact-protein, cow's milk-based infant formula (control, n=87) or the same formula with 1.0g/L 2fucosyllactose (2FL) and 0.5g/L lacto-N-neotetraose (LNnT) (test, n=88) from enrollment to 6 months; all infants received standard follow-up formula without HMOs from 6 to 12 months. Primary endpoint was weight gain through 4 months. Secondary endpoints included additional anthropometric measures, gastrointestinal tolerance, behavioral patterns, and morbidit…
Sleep, alertness and alertness management among commercial airline pilots on short-haul and long-haul flights
2016
Item does not contain fulltext Airline pilots' sleep and on-duty alertness are important focus areas in commercial aviation. Until now, studies pertaining to this topic have mainly focused on specific characteristics of flights and thus a comprehensive picture of the matter is not well established. In addition, research knowledge of what airline pilots actually do to maintain their alertness while being on duty is scarce. To address these gaps in research knowledge, we conducted a field study on a representative sample of the airline pilots of a medium-sized airline. The sample consisted of 90 pilots, of whom 30 flew long-haul (LH) routes, 30 short-haul (SH) routes, and 30 flew both. A tota…
FRI0265 Selexipag in Raynaud's Phenomenon Secondary To Systemic Sclerosis: A Randomised, Placebo-Controlled, Phase II Study
2016
Background Raynaud9s phenomenon (RP) occurs in >95% of patients (pts) with systemic sclerosis (SSc) and contributes to digital ischaemia that may lead to digital ulcers (DUs) and gangrene.1,2 Empirical treatment of SSc-associated RP includes oral vasodilators, particularly calcium channel blockers and intermittent intravenous prostacyclin analogues.3,4 However, there is a need to identify oral therapies that are more efficacious than those currently available. Objectives To determine the activity of selexipag, an oral, selective, prostacyclin receptor agonist, on RP attack frequency in pts with SSc. Methods The study comprised a placebo single-blind run-in phase of 2–4-weeks followed by an …
Opuntia Ficus Indica Edible Parts: A Food and Nutritional Security Perspective
2020
Cactus Opuntia ficus indica is widely distributed in (semi-) arid regions. Fruit and cladodes are processed into many food products. Cladodes are used as vegetables, but their main use is flour, wh...
Functional Foods: Product Development, Technological Trends, Efficacy Testing, and Safety
2020
Functional foods is a very popular term in the social and scientific media; consequently, food producers have invested resources in the development of processed foods that may provide added functional benefits to consumers’ well-being. Because of intrinsic regulation and end-of-use purposes in different countries, worldwide meanings and definitions of this term are still unclear. Hence, here we standardize this definition and propose a guideline to attest that some ingredients or foods truly deserve this special designation. Furthermore, focus is directed at the most recent studies and practical guidelines that can be used to develop and test the efficacy of potentially functional foods an…
Use of reliable bioassays to detect potential hazard of food contact materials extracts to ensure quality, safety and innovation of paperboards
2015
International audience; Food contact materials (FCM) represent a major economic issue and also an important field of innovation for packaging industries. Food packaging production must currently meet manufacturing good practices, safety for human health and thus be in compliance with the article 3 of the European Regulation 1935/2004: “Material and articles in contact with food do not transfer substances in amounts which could endanger human health…”.
When age means safety: Data to assess trends and differences on rule knowledge, risk perception, aberrant and positive road behaviors, and traffic cr…
2019
This data article examines the association between age, knowledge of traffic rules, risk perception, risky and positive behaviors on the road and traffic safety outcomes of cyclists. The data was collected using a structured self-administrable and online-based questionnaire, applied to a full sample of 1064 cyclists. The data contains 4 parts: descriptive statistics; graphical trends for each study variable according to age; Post-Hoc (Tukey-HSD) comparisons between cyclists classified in the different age groups; and, finally, the dataset for further explorations in this regard. For further information, it is convenient to read the full article entitled "Explaining Self-Reported Traffic Cra…
Characterisation of odour active compounds along extraction process from pea flour to pea protein extract
2013
International audience; Pisum sativum, rich in proteins, represents a main interest for human food. Nevertheless, pea products are underused because of their organoleptic characteristics. The extraction process of the proteins can partly explain the development of the typical flavour.The objective of the present study was to identify odour active compounds and to follow their evolution during four steps of the process (from pea flour to pea protein).Firstly, volatile compounds were extracted by Solvent Assisted Flavour Evaporation from each step and analysed by Gas Chromatography coupled with Mass Spectrometry and Olfactometry. Secondly, the volatile compounds, identified as odour active in…
