Evaluation of antitumoral and antioxidant activities of the hydroalcoholic extract and fractions obtained from the fruit pericarp of L.

The fruits of L., popularly known as '', have been used in medicine. This study evaluated the antioxidant and antitumor activities of the hydroethanolic extract (HAE) and fractions obtained from the fruit pericarp of .

Bioactive Natural Pigments' Extraction, Isolation, and Stability in Food Applications.

Color in food has multiple effects on consumers, since this parameter is related to the quality of a product, its freshness, and even its nutrient content. Each food has a characteristic color; however, this can be affected by the technological treatments that are applied during its manufacturing process, as well as its storage. Therefore, the development of new food products should take into account consumer preferences, the physical properties of a product, food safety standards, the economy, and applications of technology.

Biological Activity of Pumpkin Byproducts: Antimicrobial and Antioxidant Properties.

Pumpkin fruits are widely appreciated and consumed worldwide. In addition to their balanced nutritional profile, pumpkin species also present valuable bioactive compounds that confer biological and pharmacological properties to them. However, the seeds, peels, and fibrous strands resulting from pumpkin processing are still poorly explored by the food industry.

Natural Food Colorants and Preservatives: A Review, a Demand, and a Challenge.

The looming urgency of feeding the growing world population along with the increasing consumers' awareness and expectations have driven the evolution of food production systems and the processes and products applied in the food industry. Although substantial progress has been made on food additives, the controversy in which some of them are still shrouded has encouraged research on safer and healthier next generations. These additives can come from natural sources and confer numerous benefits for health, beyond serving the purpose of coloring or preserving, among others.

Extraction of Aloesin from Rind Using Alternative Green Solvents: Process Optimization and Biological Activity Assessment.

Aloesin is an aromatic chromone with increasing applications in the cosmetic and health food industries. To optimize its extraction from the leaf rind, the independent variables time (10-210 min), temperature (25-95 °C) and organic solvent composition (0-100%, /) were combined in a central composite design coupled with response surface methodology. The solvents consisted of binary mixtures of water with ethanol, propylene glycol, or glycerol.

Anthocyanins from L. and L. Applied as Food Colorants: A Natural Alternative.

Given the importance of colour in the general acceptance or rejection of a product, the use of colorants is a widespread practice, particularly in the food industry. At the same time, with the increasing consumers' awareness of the health effects that some artificial colorants can exert, there is a growing tendency to prioritize foodstuffs containing natural additives. In this work, L.

Bioactive and Nutritional Potential of Medicinal and Aromatic Plant (MAP) Seasoning Mixtures.

Medicinal and aromatic plants (MAPs), worldwide appreciated and used as condiments, dyes, and preservatives, possess several biological properties that justify their continuous application in the food industry. In the present study, the nutritional and chemical profiles, as well as the bioactive properties of four combinations of condiments, sold for seasoning poultry, meat, fish, and salads, were evaluated. Twenty-five phenolic compounds (HPLC-DAD-ESI/MS) were identified, with apigenin--malonyl-pentoside-hexoside as the major compound detected in all extracts.

Game-Based Learning Interventions to Foster Cross-Cultural Care Training: A Scoping Review.

Differences in cultural background between health providers and patients can reduce effective access to health services in multicultural settings. Health sciences educators have recently suggested that game-based learning may be effective for cross-cultural care training. This scoping review maps published knowledge on educational games intended to foster cross-cultural care training and highlights the research gaps for future research.

Promising Antioxidant and Antimicrobial Food Colourants from L. var. .

L. (haskap) berries are widely known for their richness in anthocyanins. In this study, such fruits were assessed for their nutritional and chemical composition, but also as sources of anthocyanins with great colouring properties to be applied in foodstuff.

Serosurveillance for vaccine-preventable diseases: A look inside the pertussis experience.

Introduction: Serological surveillance (serosurveillance) provides the most direct measure of herd immunity of vaccine-preventable diseases. Little is known about the opportunities and challenges of serosurveillance experiences, particularly pertussis.

Objective: To describe the process of serosurveillance for vaccine-preventable diseases with an emphasis on the experience of pertussis in the metropolitan area of Antioquia (Valle de Aburrá) in 2015 and 2016 and analyze the contributions and challenges for its sustainability.

Incorporating perspective analysis into critical thinking performance assessments.

Background: The International Performance Assessments of Learning (iPAL) project developed a framework for the construction of performance assessments for testing critical thinking, which proposes structuring them around a problem situation that sets an authentic (i.e., real-life-like) problem-solving task for the test-taker.

Implementation of malaria dynamic models in municipality level early warning systems in Colombia. Part I: description of study sites.

As part of the Integrated National Adaptation Pilot project and the Integrated Surveillance and Control System, the Colombian National Institute of Health is working on the design and implementation of a Malaria Early Warning System framework, supported by seasonal climate forecasting capabilities, weather and environmental monitoring, and malaria statistical and dynamic models. In this report, we provide an overview of the local ecoepidemiologic settings where four malaria process-based mathematical models are currently being implemented at a municipal level. The description includes general characteristics, malaria situation (predominant type of infection, malaria-positive cases data, malaria incidence, and seasonality), entomologic conditions (primary and secondary vectors, mosquito densities, and feeding frequencies), climatic conditions (climatology and long-term trends), key drivers of epidemic outbreaks, and non-climatic factors (populations at risk, control campaigns, and socioeconomic conditions).
