GC and GC-–MS Analysis of Volatile Compounds From Ballota nigra subsp. uncinata Collected in Aeolian Islands, Sicily (Southern Italy)
2020
In the present study, the chemical composition of the essential oils from aerial parts of Ballota nigra subsp. uncinata (Bég.) Patzak collected in Sicily was evaluated by gas chromatography (GC) and GC-mass spectrometry. The main components of the oil were ( E)-phytol (20.0%), α-pinene (9.0%), hexahydrofarnesyl acetone (5.7%), and α-selinene (5.1%). Cluster analysis of the essential oil compositions of all the taxa belonging to B. nigra s.l. group was performed.
Chemical Composition of the Essential Oil of Mentha pulegium Growing Wild in Sicily and its Activity on Microorganisms Affecting Historical Art Crafts
2017
The chemical composition of the essential oil from aerial parts of Mentha pulegium L. (Linné) collected in Sicily was evaluated by GC and GC-MS. The main components were pulegone (50.6%), piperitenone (27.8%) and menthone (6.9%). Comparison of this oil with other studied oils of different populations is discussed. The oil showed good antibacterial and antifungal activities against some microorganisms that infest historical art works.
Prenylated Flavonoids from the Roots of Tephrosia rhodesica
2020
Five new compounds—rhodimer (1), rhodiflavan A (2), rhodiflavan B (3), rhodiflavan C (4), and rhodacarpin (5)—along with 16 known secondary metabolites, were isolated from the CH2Cl2–CH3OH (1:1) extract of the roots of Tephrosia rhodesica. They were identified by NMR spectroscopic, mass spectrometric, X-ray crystallographic, and ECD spectroscopic analyses. The crude extract and the isolated compounds 2–5, 9, 15, and 21 showed activity (100% at 10 μg and IC50 = 5–15 μM) against the chloroquine-sensitive (3D7) strain of Plasmodium falciparum. peerReviewed
El futuro de los plásticos o los plásticos del futuro
2020
espanolEn los ultimos tiempos politicos, activistas ambientales, periodistas y otros lideres de opinion han dirigido sus armas contra los plasticos. Este mal concepto nace como resultado de los cambios en el entorno como consecuencia de la utilizacion de nuevas fuentes de energia, tanto nuclear como la de combustibles fosiles y el desarrollo de la industria petroquimica en especial la de los plasticos que se da a partir del descubrimiento del petroleo. Sin embargo y a pesar de las consideraciones ambientales el plastico ha construido nuestro mundo hasta el punto en que hoy es dificil imaginar nuestra vida sin el. Muchos disenadores han sostenido desde mediados del siglo XX, que los articulo…
Stem cells, cancer stem-like cells, and natural products.
2012
Somatic stem cells can be found in many rapidly regenerating tissues, e.g., the skin, gastrointestinal mucosa, and hematopoietic system, but are also present at low numbers in non-regenerative organs such as the heart and brain. In these organs, somatic stem cells aid in normal tissue homeostasis and repair after injury as well as self-renewal and the generation of specific progenitor cells during differentiation. Cancer stem-like cells are a small subpopulation of self-renewing cells that are able to proliferate upon appropriate stimulation and differentiate into heterogeneous lineages in tumors. Modulation of the behavior of normal tissue stem cells and cancer stem-like cells is an emergi…
El diseño de packaging y su contribución al desarrollo de pequeños y medianos emprendimientos
2019
El presente trabajo refiere a la problemática del diseño de packaging orientado hacia pequeños y medianos emprendimientos de diseño que requieren de packaging innovadores, personalizados y de baja serie.El objetivo de este trabajo es dar a conocer los requerimientos generales que se deben considerar al emprender un proyecto de diseño de packaging de modo que presente mayores posibilidades de éxito. Para tal fin, se establecen una serie de pautas, identificando los puntos mas sensibles e influyentes para lograr que el Sistema PP (Packaging + producto) se convierta en un elemento estratégico en el punto de venta.En esta publicación se presenta además un marco metodológico para el análisis de …
Alternative Tourism Strategies to Enhance Local Sustainable Tourism Development
2020
This chapter establishes the relationship between the ALTER-ECO project and the problem of overtourism. Background reviews the phenomenon of excess tourists based on recent research. The measures implemented in Gandia (Spain) as part of the ALTER-ECO project are described. Monitoring influx of tourists, installing Free Wi-Fi at Gandia Beach, and creating a mobile app are three measures that have contributed to easing the effects of overtourism. The debate proposes monitoring, public Wi-Fi, and gamification as three strategies for dispersing tourist load. Conclusions include measures and strategies that coincide with UNWTO 2018 recommendations.
