Pluriculturalidad, Multiculturalidad e Interculturalidad, conocimientos necesarios para la labor docente
2012
El conocimiento de la terminología derivada del fenómeno migratorio es de gran importancia para el docente de todas las etapas educativas, debido a que las aulas españolas cuentan con hijos de inmigrantes que tienen derecho a ser atendidos en igualdad de condiciones. Toda intervención educativa en situaciones de Pluriculturalidad debe partir de un conocimiento por parte del docente de lo que implican conceptos como Interculturalidad o Multiculturalidad; así, resulta imprescindible que el educador conozca esos términos relacionados con la Pluriculturalidad como base teórica de su propuesta educativa que espere desarrollar en el aula. El conocimiento de conceptos como cultura, Pluriculturalid…
Crianza, competencia parental y su relación con el desarrollo de los hijos
2014
Este artículo-comentario tiene el objetivo de analizar investigaciones recientes relacionadas con los estilos de crianza, que el artículo-objetivo ha desarrollado en el punto 2. La población participante del artículo-objetivo se encuentra en la preadolescencia y adolescencia temprana, por ello he introducido el tema describiendo la etapa educativa que cursan los chicos y chicas (10-15 años, M = 12.90, DE = 1.76) y algunas características de esta etapa del ciclo vital. A continuación me he centrado en la crianza por su peso en la predicción de la conducta prosocial, tal como queda reflejado en el artículoobjetivo. Dentro de la crianza he ampliado la información teórica y he analizado la impo…
Molecular characterization of cucumber mosaic virus isolates infecting ornamental species cultivated in the botanical garden of Bologna university.
2006
During an epidemiological survey carried out in the Botanical Garden at Bologna University, Cucumber mosaic virus (CMV) has been detected by applying PAS-ELISA technique infecting some ornamental species exhibiting a severe symptomatology on the leaves. Datura innoxia Miller. showed mosaic and leaf-curling; Globularia nudicaulis L. produced narrowed leaves with a yellow mosaic and/or variegation; Eupatorium cannabinum L. showed a systemic chlorotic and/or yellow mosaic and stunting. Reverse transcription-polymerase chain reaction (RT-PCR) and single strand conformation polymorphism (SSCP) were employed to characterise these CMV isolates. Total RNA was extracted from symptomatic leaf samples…

SKRINING FITOKIMIA, UJI AKTIVITAS ANTIMIKROBA DAN ANTITUMOR TUMBUHAN OBAT KABUPATEN MANOKWARI
2008
<p><em>Pythochemistry screening and testing of antimicrobial and antitumor activities was carried out on 31 species of medicinal plants distributed around Manokwari Regency. All parts of the plants were collected and screened for the presence of alkaloids, saponins, and tannins; antimicrobial and antitumor activity. The number of positive tests obtained are 17 (55, 3%) for alkaloids, 6 (19, 4%) for saponins, and 26 (84, 7%) for tannins. Eleven species shown inhibition activities (antimicrobial) to Candida albicans, Staphyloccocus aureus, and Echericia colii while only seven species have antitumor activity, especially against tumor cell P-388. </em></p>
Characterization and variation of bacterial and fungal communities from the sapwood of Apulian olive varieties with different susceptibility toXylell…
2020
AbstractEndophytes are symptomless fungal and/or bacterial microorganisms found in almost all living plant species. The symbiotic association with their host plants by colonizing the internal tissues has endowed them as a valuable tool to suppress diseases, to stimulate growth, and to promote stress resistance. In this context, the identification of cultivable endophytes residing the sapwood of Apulian olives might be a promising control strategy for xylem colonizing pathogens asXylella fatidiosa. To date, olive’s sapwood cultivable endophytes are still under exploration; therefore, this work pursues a study of diversity and occurrence variation of cultivable endophytes in the sapwood of di…
Immunomodulatory and Hematopoietic Effects of Recombinant Human Interleukin-6 in Patients with Advanced Renal Cell Cancer
1996
Interleukin-6 (IL-6) is a cytokine with pleiotropic biologic activities on B cells, T cells, and hematopoietic progenitors. The present study was undertaken to assess pharmacodynamic effects of subcutaneous administration of IL-6 on blood counts, immunologic parameters, and acute-phase reactants. Blood samples were taken from patients with advanced renal cell cancer participating in a phase II trial of recombinant human IL-6. Multiparameter FACS analyses of peripheral blood mononuclear cells were performed using antibodies against CD3, CD4, CD8, HLA-DR, CD56, CD28, CD38, CD19, sIgM, and sIgG. Serum levels of IL-10, soluble CD23 (sCD23), sCD25, IL-1 receptor antagonist protein (IL-1RA), solu…
Interaction between Longitudinal Shear and Transverse Bending in Prestressed Concrete Box Girders
2017
In box girder bridges, the quantity and distribution of reinforcement to be put in concrete elements of sections can be evaluated only by considering the deformation of the cross section in addition to the longitudinal analysis of the static scheme, establishing the entire state of stress of box sections. This leads to a need to evaluate the interaction between internal forces obtained by the global analysis and the ones obtained by the local analysis of the cross sections. The frame effect implies the elastic deformation of slabs and webs, whereas eccentrically applied loads lead to cross-section distortion with the loss of the box shape. Hence, the reinforcement is strongly influenced by …
Molecular surveillance of norovirus, 2005–16 : an epidemiological analysis of data collected from the NoroNet network
2018
BACKGROUND: The development of a vaccine for norovirus requires a detailed understanding of global genetic diversity of noroviruses. We analysed their epidemiology and diversity using surveillance data from the NoroNet network.METHODS: We included genetic sequences of norovirus specimens obtained from outbreak investigations and sporadic gastroenteritis cases between 2005 and 2016 in Europe, Asia, Oceania, and Africa. We genotyped norovirus sequences and analysed sequences that overlapped at open reading frame (ORF) 1 and ORF2. Additionally, we assessed the sampling date and country of origin of the first reported sequence to assess when and where novel drift variants originated.FINDINGS: W…
Carbon Monoxide Protects Against Ischemia-reperfusion Injury in Vitro via Antioxidant Properties
2012
Carbon monoxide (CO) is believed to mediate many of the cytoprotective effects attributed to the activation of heme oxygenase (HO-1), the enzyme responsible for CO production. Recently, the study of CO-releasing molecules (CO-RMs) has provided a new approach for the delivery of CO. In the present study, we examined whether the cardioprotective properties of CO-RM2 in isolated rat hearts subjected to an ischemia-reperfusion (I/R) sequence were associated with the presence of CO. In addition, the antioxidant properties of CO-RM2 were evaluated. In hearts pretreated with CO-RM2, the improvement in contractile function at the end of the reperfusion period after 20 min of global total ischemia w…
