L'epcidina e il suo ruolo nell'omeostasi del ferro a livello cardiaco.

L’epcidina (HAMP) è un ormone peptidico coinvolto nella regolazione sistemica dell’omeostasi del ferro e risulta essere espresso anche a livello cardiaco. Questo studio è stato condotto per approfondire le conoscenze riguardo al ruolo dell’epcidina e dei geni regolatori del ferro e il loro coinvolgimento nella patologie cardiache. Sono stati condotti studi sull’atassia di Friedreich (FRDA), una patologia neurodegenerativa caratterizzata dallo sviluppo di una cardiomiopatia da sovraccarico di ferro. A tale scopo, sono stati derivati cardiomiociti da cellule staminali pluripotenti indotte umane (hiPSCs) di un paziente affetto da FRDA e da un soggetto sano (Ctr) e in queste cellule è stata analizzata l’espressione del gene HAMP. I risultati ottenuti hanno evidenziato un aumento significativo dell’espressione genica di HAMP nei cardiomiociti FRDA rispetto ai controlli. Parallelamente, l’espressione genica di HAMP e di altri geni regolatori del ferro è stata analizzata in un modello animale murino sottoposto a ipossia intermittente (IH) e a un danno ischemico indotto dalla legatura coronarica (LAD). Nel gruppo di topi normossici sottoposti alla legatura coronarica (Normo LAD) è stata evidenziato un aumento dell’espressione genica di HAMP simile a quello riscontrato nei cardiomiociti FRDA, suggerendo che questo gene potrebbe essere indotto in presenza di un danno cardiaco. Inoltre, l’espressione della ferritina, una proteina coinvolta nello storage del ferro con attività antiossidante, rimane invariata nei topi sottoposti a un danno cardiaco come la LAD, mentre risulta essere aumentata nei topi sottoposti a IH. Pertanto, l’aumento di espressione della ferritina potrebbe contribuire ai meccanismi di cardioprotezione indotti dall’ipossia intermittente. I risultati di espressione genica ottenuti in questo studio saranno validati mediante studi di espressione proteica.

Euphorbia tirucalli L.–Comprehensive Characterization of a Drought Tolerant Plant with a Potential as Biofuel Source

Of late, decrease in mineral oil supplies has stimulated research on use of biomass as an alternative energy source. Climate change has brought problems such as increased drought and erratic rains. This, together with a rise in land degeneration problems with concomitant loss in soil fertility has inspired the scientific world to look for alternative bio-energy species. Euphorbia tirucalli L., a tree with C3/CAM metabolism in leaves/stem, can be cultivated on marginal, arid land and could be a good alternative source of biofuel. We analyzed a broad variety of E. tirucalli plants collected from different countries for their genetic diversity using AFLP. Physiological responses to induced drought stress were determined in a number of genotypes by monitoring growth parameters and influence on photosynthesis. For future breeding of economically interesting genotypes, rubber content and biogas production were quantified. Cluster analysis shows that the studied genotypes are divided into two groups, African and mostly non-African genotypes. Different genotypes respond significantly different to various levels of water. Malate measurement indicates that there is induction of CAM in leaves following drought stress. Rubber content varies strongly between genotypes. An investigation of the biogas production capacities of six E. tirucalli genotypes reveals biogas yields higher than from rapeseed but lower than maize silage.

Esta cepa es adecuada para su empleo en acuicultura (alimentación de larvas de peces y moluscos) y en la obtención de EPA y/o de un aceite rico en EPA y en DHA necesarios para la nutrición y salud humanas.

Studio geologico-geomorfologico per la soluzione di problematiche tecnico-applicative nelle località Terra Murata (borgo medievale e costone lato Marina Corricella) e Centane-Panoramica (Isola di Procida, Golfo di Napoli)

Nel presente rapporto tecnico viene illustrato uno studio del dissesto geomorfologico in due aree selezionate dell’Isola di Procida, rispettivamente ubicate nella zona storica di Procida (borgo medievale di Terra Murata lungo la Via Salita Castello-altezza Via S. Domenico) e nell’area costiera che raccorda Punta Pizzaco con Punta Solchiaro (comprensorio Centane-Panoramica). In generale le finalità del rapporto tecnico sono quelle di fornire un inquadramento di queste due zone da un punto di vista geologico, che si differenziano negli aspetti particolari. Infatti, nella zona di Terra Murata, sia nella zona alta del borgo medievale (piazzale oltre le mura) che lungo il costone tufaceo antistante la Marina Corricella (salita Castello all’altezza di Via S. Domenico) sono documentate copiose perdite d’acqua attraverso i terreni vulcanici di natura tufacea e pozzolanica che affiorano nell’area. Tali perdite d’acqua attraverso i terreni interessano anche numerose abitazioni, creando disagi che rendono necessario l’ulteriore accertamento tecnico al fine di individuare, anche tentativamente, le cause di tali dissesti e di proporre soluzioni tecnicamente soddisfacenti a tali problematiche attraverso uno studio approfondito.

Avances y desafíos de la agenda de cambio climático en la Zona Costero-Marina de El Salvador

Central America is one of the most vulnerable regions to the adverse effects of climate change, due to the rise of frequency and intensity that hydrometeorological phenomena have occurred in recent years. In El Salvador 484 people died and 800,000 more were affected because these extreme events and economic losses reached up to 6.711 million dollars. According to the climate projections over the next 50 years in the territory, is expected that extreme events such as droughts and rainfall will intensify. Within the last 30 years, July of 2014 is considered the one with less rainfall. Meanwhile, Tropical Depression 12E in 2011 provoked an outstanding rainfall average of 1,137 mm, affecting more than 500,000 people; most of them live in the coastal zone. The death of 34 people and living economic losses of 840.4 million was recorded, equivalent to 4% of GDP. El Salvador has policies, national plans and strategies aimed to reducing vulnerability, promoting adaptation to these changes and more effective risk management. This paper compiles the impacts of climate variability in El Salvador and the efforts of the State on adaptation to improve environmental and social resilience.

Comparative study of bioactive potential of Fueniculum vulgare Mill. and Matricaria recutita L. phenolic rich extracts to functionalize cottage chesse

Synthetic additives used in a wide variety of food products have been associated to some toxic effects. This conducted to an increasing interest of consumers for natural additives, including food preservers [1]. Many aromatic herbs have been used to prepare bioactive extracts with benefits to the consumer's health. Foeniculum vulgare Mill. (fennel) and Matricaria recutita L. (chamomile) are examples of popular herbs rich in phenolic compounds with documented antioxidant and antimicrobial properties [2,3]. The present work confirms the antioxidant (DPPH scavenging activity, reducing power and lipid peroxidation inhibition) and antimicrobial (against bacteria such as Bacillus cereus and Salmonella Typhimurium and fungi such as Aspergillus niger, A. versicolor and PenicilliumfimicuJosum) activities of fennel and chamomile extracts, obtained by decoction. The chemical characterization of the extracts, performed by HPLC-DAD-ESIIMS, revealed the presence of five flavonoids (mainly qercetin-3-0- glucoside) and twelve phenolic acids (mainly 5-0-caffeolyquinic acid) for fennel extract and the presence of nine flavonoids (mainly luteolin-0-glucuronide) and ten phenolic acids (mainly di-caffeoyl-2,7- anhydro-3-deoxy-2-octulopyranosonic acid) for chamomile extract. Due to their high antioxidant and antimicrobial activities, both extracts were then incorporated (at DPPH scavenging activity EC25 value: 0.35 mg/mL and 0.165 mg/mL for fennel and chamomile, respectively) in cottage cheeses (prepared by Queijos Casa Matias Lda) as natural additives with two objectives: to increase the shelf-life of the cottage cheeses and to provide bioactive properties to the final products. The results showed that the use of these natural extracts did not alter significantly the nutritional characteristics of the cottage cheese in comparison with control samples (cottage cheese without extracts), but improved its antioxidant potential (more evident in the samples with chamomile extract). After 14 days of storage, only the control samples showed signs of degradation. Overall, the present study highlights the preservation potential of fennel and chamomile extracts in cottage cheeses, improving also their bioactivity.

Plan promocional para incentivar y desarrollar mercado de productos a base de plantas medicinales, elaborados por la Asociación cooperativa de productores agropecuarios Telegüisil de R.L., del cantón San Lucas del municipio de Cuisnahuat, departamento de Sonsonate.

En la actualidad los productos elaborados a base de plantas medicinales no son muy conocidos, ya que sus productores por lo general carecen de los mecanismos adecuados de promoción y comercialización, de la capacidad económica para darlos a conocer de manera efectiva en los municipios de Sonsonate y Cuisnahuat. Por las razones anteriores se diseñó un “Plan Promocional para incentivar y desarrollar mercado de productos a base de plantas medicinales, elaborados por la Asociación Cooperativa de Productores Agropecuarios Tepegüisil de R. L., del Cantón San Lucas del municipio de Cuisnahuat, Departamento de Sonsonate” que es el tema con que se identifica esta investigación. Este proyecto se llevará a cabo con el apoyo de la Asociación El Bálsamo, que tiene como objetivo contribuir al desarrollo humano sustentable y al fortalecimiento del sector microempresarial urbano y rural a través de servicios financieros sostenibles, capacitación integral y asociatividad empresarial auto gestora. La metodología de investigación que se ha utilizado está compuesta por el método científico, el tipo de investigación es descriptiva; también fuentes de investigación primarias como: los miembros de la Asociación Cooperativa Tepegüisil, el Director de Proyectos de la Asociación El Bálsamo, clientes reales y potenciales; al mismo tiempo entre las fuentes secundarias utilizadas están: documentos, libros y tesis relacionadas al tema, páginas en Internet y toda la información proporcionada por la Asociación El Bálsamo fueron de mucha importancia para conocer la situación actual de esta entidad. Mediante las encuestas y entrevistas realizadas a los miembros de la Asociación Cooperativa y al Director de Proyectos de El Bálsamo, se pudo comprobar que los productos a base de plantas medicinales que elaboran no poseen estrategias de promoción y comercialización que les permita incentivar y desarrollar el mercado. Con el propósito de establecer las herramientas de promoción y comercialización de dichos productos se propone implementar estrategias de Publicidad, Promoción de Ventas, Venta Personal y Relaciones Públicas; además utilizar el logotipo rediseñado y el eslogan denominado “lo natural en tu cabello y tu piel”.
