diseases. Nutritional interventions promoting high-quality dietary patterns with low caloric intake value and high nutrient
density (ND) could be linked to a better control of CVD risk and recurrence of coronary disease. This study aims to assess
the efects of a dietary intervention based on MedDiet or Low-Fat dietary intervention over changes in ND and food intake
after 1 and 7 years of follow-up of the CORDIOPREV study.
Methods We prospectively analyzed the results of the 802 coronary patients randomized to two healthy dietary patterns
(MedDiet=425, Low-Fat Diet=377) who completed the 7 years of follow-up and had all the dietary data need. Dietary
intake information obtained from a validated 137-item Food Frequency Questionnaire was used to calculate 1- and 7-year
changes in dietary intake and ND (measured as nutrient intake per 1000 kcal). T test was used to ascertain diferences in food
intake and ND between groups across follow-up time. Within-subject (dietary allocation group) diferences were analyzed
with ANOVA repeated measures.
Results From baseline to 7 years of follow-up, signifcant increases of vegetables, fruits, and whole cereals within groups
(p<0.001) was found. We found a higher increase in dietary intake of certain food groups with MedDiet in comparison with
Low-Fat Diet for vegetables (46.1 g/day vs. 18.1 g/day, p<00.1), fruits (121.3 g/day vs. 72.9 g/day), legumes (4.3 g/day vs.
0.16 g/day) and nuts (7.3 g/day vs. − 3.7 g/day). There was a decrease in energy intake over time in both groups, slightly
higher in Low-Fat Diet compared to MedDiet group (− 427.6 kcal/day vs. − 279.8 kcal/day at 1st year, and − 544.6 kcal/
day vs. − 215.3 kcal/day after 7 years of follow-up). ND of all the nutrients increased within group across follow-up time,
except for Saturated Fatty Acids (SFA), cholesterol and sodium (p<0.001).
Conclusions A comprehensive dietary intervention improved quality of diet, reducing total energy intake and increasing the
intake of healthy food groups and overall ND after 1 year and maintaining this trend after 7 years of follow-up. Our results
reinforce the idea of the participation in trials, enhance nutrition literacy and produces better nutritional outcomes in adult
patients with established CVD.

Ternary Quantum Dots in Chemical Analysis. Synthesis and Detection Mechanisms
Ternary quantum dots (QDs) are novel nanomaterials that can be used in chemical analysis due their unique physicochemical and spectroscopic properties. These properties are size-dependent and can be adjusted in the synthetic protocol modifying the reaction medium, time, source of heat, and the ligand used for stabilization. In the last decade, several spectroscopic methods have been developed for the analysis of organic and inorganic analytes in biological, drug, environmental, and food samples, in which different sensing schemes have been applied using ternary quantum dots. This review addresses the different synthetic approaches of ternary quantum dots, the sensing mechanisms involved in the analyte detection, and the predominant areas in which these nanomaterials are usedThe authors give thanks to the CONACYT support for the grant number 771019S
Impedimetric Biosensor Based on a Hechtia argentea Lectin for the Detection of Salmonella spp.
A sensitive electrochemical detection method for Salmonella spp. was described, based on the use of Hechtia argentea lectin immobilised on a screen-printed gold electrode. The lectin was extracted from Hechtia argentea, a plant belonging to the Bromeliaceae family. The lectin with molecular weight near 27.4 kDa showed selectivity towards D-mannose, contained on the lipopolysaccharide cell wall of Salmonella spp. Carbohydrate selectivity of the lectin was measured as a change in impedance with respect to concentration. The binding of the bacteria to the biosensor surface increased impedance with increasing concentrations of Salmonella spp., achieving a linear range of detection of 15–2.57 × 107 CFU mL−1, with a limit of detection of 5 CFU mL−1. Increases in impedance were measured using electrochemical impedance spectroscopy and analysed using Nyquist plots. The biosensor was applied in analysis of hen egg samples, and the results were consistent with those obtained using the official analysis methodologyS
Planning and management of ecological tourism of the Middle Eastern Atlas in Morocco
La diversificación de los productos turísticos en Marruecos se revela como uno de los principios básicos para el impulso y el crecimiento económico del país, según el documento Estrategia del desarrollo turístico. Visión 2.010.
Actualmente Marruecos presenta una oferta polarizada en el turismo convencional (sol y playa, desierto, ciudades imperiales). El turismo ecológico es una de las posibles alternativas dada la diversidad de los paisajes y de los recursos ecológicos del país. En este artículo se presentan las potencialidades de cara al ecoturismo del Medio Atlas oriental al sur de Taza, señalando fortalezas y oportunidades, así como detectando los principales puntos débiles. Se trata de una zona con interesantes valores ecológicos y naturales que, debidamente planificada y gestionada, puede ofertarse para el disfrute de los visitantes, la conservación de las riquezas naturales y el crecimiento económico de la región.
Para ello se realiza una serie de propuestas de planificación y gestión basadas en el estudio de las comunidades rurales allí asentadas, en el análisis directo de los recursos ecológicos y en los nuevos escenarios de cooperación y planificación socio-económica de Marruecos.La diversificaciò dels productes turístics al Marroc es revela com un dels principis bàsics per a l'impuls i el creixement econòmic del país, segons el document Estrategia del desarrollo turístico.Visión 2.010.

Magnetic molecularly imprinted stirring bar for isolation of patulin using grafting technique
The 19th International Electronic Conference on Synthetic Organic Chemistry session Polymer and Supramolecular ChemistryMycotoxins are low-molecular-weight natural products with great structural diversity produced as secondary metabolites by fungi. One of the principal toxic fungal metabolites is patulin (PAT), produced by over 30 genera of mold including species as Penicillium expansum or Penicillium griseofulvum, and normally related to vegetable-based products and fruit, mainly apple. These mold grow easily in damaged fruit or in derived-product as juices if storage conditions are deficient. Some of the most serious effects of PAT ingestion are agitation, convulsions, edema, ulceration intestinal, inflammation and vomiting. Thus, European Regulation 1881/2006 established a maximum content of 10 ppb in infant fruit juices, 50 ppb for fruit juices in adults and 25 ppb in fruit-derived products. Nowadays, the official analytical method for food adopted by AOAC International is HPLC with UV detection, using clean-up with ethyl acetate and sodium carbonate. However, the diverse drawbacks of this method (poor stability of PAT under alkaline extraction, poor resolution between PAT and co-extracted hydroxymethylfurfural) have originated interest in alternative options, such as LC methods coupled to mass spectrometry. In the last years, purification with molecularly imprinted polymers (MIP) started to be used, and are becoming promising materials for extracting different analytes present in food. Mycotoxins are too toxic or too expensive to be used as template molecules in MIP preparation. Template “bleeding” may be an additional problem, especially when dealing with very low detection levels. In the present work, a rapid and selective method based on magnetic molecularly imprinted stir-bar (MMIB) extraction has been developed for the isolation of PAT. A structural analogue, 2-oxindole, was used as dummy template. The polymer was grafted to the silanized glass surface of the stir ba
Strategic planning research through fifty years of Long Range Planning: a bibliometric overview
Long Range Planning (LRP) is the first journal focused on strategic planning. It was created in 1968 by the
Long Range Planning Society, and it celebrated its 50th anniversary in 2018. This event led to the presentation
of a complete bibliometric study aimed at identifying the most significant results that occurred in the journal
during this period. For this purpose, bibliometric data were collected from the Web of Science Core Collection
database, and two bibliometric approaches were used to analyze the journal's publications: a performance
analysis and a graphical mapping of the literature. The first of these uses a wide range of productivity and
influence indicators that include the number of publications and citations, the h-index, and citations by paper,
among others. The second approach uses the VOSviewer software to deliver a graphical view of the various
intellectual connections within LRP. The results of both bibliometric approaches are consistent and confirm
LRP as a leading journal in strategic planning and management, with increasing participation of authors and
universities from countries around the world
