Olive oil intake and cancer risk: A systematic review and meta-analysis
2022
Background Research evidence has established the beneficial effects of diet in cancer prevention; various epidemiological studies have suggested that olive oil component could play a role in decreasing cancer risk. This systematic review and meta-analysis aims to investigate the association between olive oil consumption, cancer risk and prognosis. Methods A systematic search was conducted in PubMed, EMBASE and Google Scholar databases (end-of-search: May 10, 2020). Pooled relative risk (RR) and 95% confidence intervals (95% CIs) were estimated with random-effects (DerSimonian-Laird) models. Subgroup analyses, sensitivity analyses and meta-regression analysis were also performed. Results 45…
Quantitative importance of staminodes for female reproductive success inParnassia palustrisunder contrasting environmental conditions
2003
The five sterile stamens, or staminodes, in Parnassia palustris act both as false and as true nectaries. They attract pollinators with their conspicuous, but non-rewarding tips, and also produce nectar at the base. We removed staminodes experimentally and compared pollinator visitation rate and duration and seed set in flowers with and without staminodes in two different populations. We also examined the relative importance of the staminode size to other plant traits. Finally, we bagged, emasculated, and supplementary cross-pollinated flowers to determine the pollination strategy and whether reproduction was limited by pollen availability. Flowers in both populations were highly dependent o…
Regional climate model simulations for Europe at 6 and 0.2 k BP: sensitivity to changes in anthropogenic deforestation
2014
International audience; This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in the Holocene, ∼ 6 and ∼ 0.2 k BP in Eu-rope. We apply the Rossby Centre regional climate model RCA3, a regional climate model with 50 km spatial resolution, for both time periods, considering three alternative descriptions of the past vegetation: (i) potential natural vegetation (V) simulated by the dynamic vegetation model LPJ-GUESS, (ii) potential vegetation with anthro-pogenic land use (deforestation) from the HYDE3.1 (History Database of the Global Environment) scenario (V + H3.1), and (iii) potential vegetation with anthropogenic land …
Algunas citas de interés para la flora valenciana (norte de Alicante)
2008
Se presentan algunos resultados de una catalogación florística realizada en la Estación Biológica de Torretes-Font Roja, situada en las inmediaciones del Parque Natural del Carrascar de la Font Roja (Ibi-Alcoy, Alicante). De los más de 200 táxones catalogados destacamos por su rareza en la Comunidad Valenciana: Linaria repens (L.) Mill. subsp. blanca (Pau) Rivas Godoy & Borja, cuya presencia en la provincia de Alicante se limita a unas pocas citas en las próximas Sierras de Castalla y del Maigmó; Gypsophila pilosa Hudson, arqueófito muy raro ligado a los cultivos tradicionales de cereal y a los consiguientes barbechos, cuyas citas recientes son casi nulas, y Prunus acida C. Koch, especie ar…

Taxonomic and nomenclatural novelties concerning the Valencian flora (eastern Spain), III
2014
Como parte de la Actualización taxonómica y nomenclatural de la flora vascular de la Comunidad Valenciana, se proponen cuatro combinaciones nuevas y una nueva subespecie, en los géneros Centaurea, Galium, Knautia, Lepidium y Satureja. As a part of the taxonomical and nomenclatural update of the vascular flora of the Valencian Community, four new nomenclatural combinations and one new subspecies name are proposed in the genera Centaurea, Galium, Knautia, Lepidium and Satureja.
Teucrium ronnigeri Sennen (Lamiaceae) y sus variaciones
2009
Se aportan datos sobre Teucrium ronnigeri Sennen, nombre prioritario para el endemismo iberolevantino que ha venido denominándose T. aureum subsp. latifolium o T. homotrichum. Se discute su variabilidad morfológica a lo largo de su área de distribución, sobre todo en lo que afecta a la coloración general de la planta, anchura de las hojas superiores, color de la corola y tamaño de los cálices y glomérulos florales. Pese a la enorme variación observada, se acepta que las poblaciones del extremo meridional de Alicante y áreas limítrofes con Murcia, constituyen una entidad particular, para la que se propone la nueva combinación T. ronnigeri subsp. lagunae, la cual se diferencia de la típica, T…
Medicinal Plants for Insomnia Related to Anxiety: An Updated Review.
2021
AbstractSleep disorders are common among the general population and can generate health problems such as insomnia and anxiety. In addition to standard drugs and psychological interventions, there are different complementary plant-based therapies used to treat insomnia and anxiety. This review aimed to find and examine the most recent research on the use of herbal medicines for treating anxiety and insomnia as compiled from clinical trials, as well as to assess the safety and efficacy of these medicines and to elucidate their possible mechanisms of action. The process entailed a search of PubMed, Scopus, and the Cochrane Library databases from 2010 to 2020. The search terms included “sleep d…
Human Simulation and Sustainability : Ontological, Epistemological, and Ethical Reflections
2020
This article begins with a brief outline of recent advances in the application of computer modeling to sustainability research, identifying important gaps in coverage and associated limits in methodological capability, particularly in regard to taking account of the tangled human factors that are often impediments to a sustainable future. It then describes some of the ways in which a new transdisciplinary approach within &ldquo
