Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems
2020
Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing th…
Regeneración de cartílago mediante el uso de células madre de pulpa dental humanas (hDPSCs)
2020
El tejido cartilaginoso es un tejido fundamental, puesto que proporciona sostén a nuestro organismo. Cuando el cartílago articular se lesiona experimenta una regeneración compleja y limitada. Por ello es importante buscar alternativas y ampliar las soluciones que se están utilizando actualmente para tratar enfermedades en las que se produce la alteración del cartílago articular, como la osteoartritis. Con la base en esta idea, recientemente la ingeniería tisular ha desarrollado distintas herramientas para tratar de regenerar el cartílago cuando la regeneración por otras vías no es posible. Dentro de las estrategias que existen, se ha potenciado el uso de hidrogeles combinados con condrocito…
Nueva estrategia para la derivación de hepatocitos funcionales de mujeres afectas de deficiencia en ornitina transcarbamilasa
2022
La DOTC es una enfermedad ligada al sexo (Cromosoma X) que se incluye dentro de un grupo de enfermedades denominadas trastornos del ciclo de la urea. Es un trastorno metabólico cuyo resultado es la acumulación de amonio en la sangre produciéndose episodios hiperamonemia con diferentes grados de severidad. Esto sucede como consecuencia de una mutación en el gen de la OTC, perdiéndose dicha actividad enzimática. La forma más letal de DOTC sucede en el periodo perinatal, y aunque en la actualidad existen tratamientos como dietas bajas en proteínas, o administración de fármacos como los “scavengers” de amonio, estos no suponen una solución en pacientes pediátricos con síntomas graves y crónicos…
Monitoring Commercial Starter Culture Development in Presence of Red Grape Pomace Powder to Produce Polyphenol-Enriched Fresh Ovine Cheeses at Indust…
2021
Red grape Nero d’Avola cultivar grape pomace powder (GPP) was applied during fresh ovine cheese production in order to increase polyphenol content. Before cheeses were produced, the bacteria of a freeze-dried commercial starter culture were isolated and tested in vitro against GPP. Two dominant strains, both resistant to GPP, were identified. Thestarter culture was inoculated in pasteurized ewe’s milk and the curd was divided into two bulks, one added with 1% (w/w) GPP and another one GPP-free. GPP did not influence the starter culture development, since lactic acid bacteria (LAB) counts were 109 CFU/g in both cheeses at 30 d. To exclude the interference of indigenous LAB, the pasteurized m…

Motorisen oppimisen vaikeuden tunnistaminen ja tukeminen kouluympäristössä
2018
Motorisen oppimisen vaikeudella, kuten kehityksellisellä koordinaatiohäiriöllä (DCD), tarkoitetaan huomattavaa vaikeutta oppia uusia motorisia taitoja ja soveltaa jo opittuja taitoja uusiin tilanteisiin. Tämän tutkimuksen tarkoituksena oli kehittää opettajien käyttöön havainnointityökalu, joka auttaa tunnistamaan motorisen oppimisen vaikeuden esi- ja alkuopetusikäisillä lapsilla. Lisäksi tutkimus selvitti, miten opettajat voivat kouluympäristössä tukea lapsia, joilla on haasteita motorisessa oppimisessa. Tutkimus muodostui neljästä osatutkimuksesta. Ensimmäisessä tutkittiin systemaattisen kirjallisuuskatsauksen avulla maailmalla käytössä olevien havainnointilomakkeiden psykometrisiä ominais…
Technical English for agriculture
2021
As the world goes global, the agricultural business needs to move across frontiers and oceans. Food, raw and processed, is regularly transported across continents. As space is no longer a limit for food trade and human nutrition, language cannot represent a barrier to this continuous exchange. In the last 60 years, English has been taking a foothold as the primary language for world trade and the exchange of agricultural goods is no exception. Agricultural sciences embrace a large number of disciplines, from botany to environmental physiology, from soil science to meteorology, from plant propagation to cultural management, from soil management to pest control, from field crops to animal husb…
Characterization of Erwinia gerundensis A4, an Almond-Derived Plant Growth-Promoting Endophyte
2021
The rapidly increasing global population and anthropogenic climate change have created intense pressure on agricultural systems to produce increasingly more food under steadily challenging environmental conditions. Simultaneously, industrial agriculture is negatively affecting natural and agricultural ecosystems because of intensive irrigation and fertilization to fully utilize the potential of high-yielding cultivars. Growth-promoting microbes that increase stress tolerance and crop yield could be a useful tool for helping mitigate these problems. We investigated if commercially grown almonds might be a resource for plant colonizing bacteria with growth promotional traits that could be use…
Effectiveness of spinosad and mineral oil for control of Grapholita funebrana Treitschke in organic plum orchards
2012
An experiment was conducted in an organic plum orchard in Sicily to evaluate the damage caused by the plum moth Grapholita funebrana (Treitschke) to three plum cultivars (Angeleno, Friar, and Stanley) and to evaluate plum moth control provided by mineral oil applied every 20 days (Moil), spinosad applied every 10 days (S10), or spinosad and mineral oil applied alternately (S/Moil). Treatment application began when eggs were first observed on fruits. S10 and S/Moil effectively reduced plum moth damage on all cultivars but Moil did not. Plum moth infestation was significantly lower on Stanley than on Friar and Angeleno.
