STUDY ON CONVERSION OF ENCAPSULATED VITRO-DERIVED PROPAGULES OF 'C35' CITRANGE [C. SINENSIS (L.) OSB. × P. TRIFOLIATE (L.) RAF.]
2015
Fight against Citrus tristeza virus (CTV) implies the use of CTV-resistant rootstocks, such as citranges [C. Sinensis (L.) Osb. × P. Trifoliata (L.) Raf.]. The 'C35' represents a promising tolerant to CTV genotype. The employment of innovative in vitro techniques, such as encapsulation, could open new perspectives for this genotype propagation, particularly in the nursery activity. Preliminary experiments on calcium-alginate encapsulation of microcuttings (unipolar propagules) have already been performed to evaluate the use of tissue culture for the propagation and the preservation of different citrange rootstocks: Carrizo and Troyer. In the present study, the influence of different types a…
Harmful and Protective Effects of Terpenoids from African Medicinal Plants
2014
Terpenoids represent the most widespread group of natural products and can be found in all classes of living things. Many defensive compounds include sesquiterpenoids and diterpenoids from angiosperm species. Several terpenoids are biologically active and are exploited in the fight against cancer, malaria, inflammation, and a variety of infectious diseases. Nonetheless, some compounds of this group showed toxic effects causing gastrointestinal problems or central nervous system manifestations among others. Several bioactive terpenoids were identified in African medicine with numbers of them having organ-protective effects while few are known for their nonbeneficial properties for humans. In…
Structure and dynamics of RNA guanine quadruplexes in SARS-CoV-2 genome. Original strategies against emerging viruses
2021
Guanine quadruplexes (G4) structures in viral genome have a key role in modulating viruses’ biological activity. While several DNA G4 structures have been experimentally resolved, RNA G4s are definitely less explored. We report the first calculated G4 structure of the RG-1 RNA sequence of SARS-CoV-2 genome, obtained by using a multiscale approach combining quantum and classical molecular modelling and corroborated by the excellent agreement between the corresponding calculated and experimental circular dichroism spectra. We prove the stability of RG-1 G4 arrangement as well as its interaction with G4 ligands potentially inhibiting viral protein translation.
The role of executive function in social competence and behavioral problems in the last year of preschool
2018
Diverse studies have found a relationship between executive function, behavioral problems and social competence. However, until this moment, few studies have investigated the role of the distinct components of executive function in social competence, or in the most frequently encountered behavioral problems in childhood education. For this reason, the principal objective of this article is to evaluate the relation of the exec-utive functions with behavioral problems and social competence in infancy. The study included 260 students in their last year of preschool. The results of path analysis showed that all components of executive functions predict, at least, a behavioral problem. However, …
Daily physical activity and physical activity in soccer practice with children
2017
Päivittäisen fyysisen aktiivisuuden määrässä ja intensiteetissä on eroja ihmisten välillä. Suurin osa fyysisestä aktiivisuudesta tapahtuu vapaa-ajalla, lapsilla koulupäivän ulkopuolella. Liikuntasuositukset ohjeistavat riittävästä päivittäisen fyysisen aktiivisuuden määrästä ja laadusta. Yhä useammat lapset eivät saavuta näitä suosituksia ja jako aktiivisiin ja vähemmän aktiivisiin lapsiin on tullut entistä selkeämmäksi. Osallistumista ohjattuun liikuntaan on pidetty yhtenä ratkaisuna lisätä lasten päivittäisen fyysisen aktiivisuuden määrää. Tutkimukset kuitenkin ovat osoittaneet, ettei järjestettyyn liikuntaan osallistuminen kasvata lasten kokonaisaktiivisuutta. Saman päivän aikana tapahtu…
Dermatofibrosarcoma protuberans: estudio de factores pronósticos
2012
Introducción: El dermatofibrosarcoma protubernas (DFSP) es un tumor cutáneo de malignidad intermedia clasificado dentro de los tumores fibrohistiocíticos que tiene una alta tasa de recidivas locales tras extirpaciones con cirugía convencional pero baja capacidad de producir metástasis. Hipótesis: Existen determinadas características del DFSP que condicionan un crecimiento más infiltrativo, asimétrico e impredecible, lo que supone mayor morbilidad para el paciente y una mayor dificultad para su tratamiento. Objetivos: 1.-Realizar un análisis observacional y descriptivo de una serie de casos de DFSP que han sido vistos en el Servicio de Dermatología del IVO, según las características epidemio…

Labile carbon addition affects soil organisms and N availability but not cellulose decomposition in clear-cut Norway spruce forests
2014
We assessed the effects of sucrose addition on the biological and chemical properties of organic soil in clear-cut Norway spruce forests managed with or without wood-ash fertilization and mechanical site preparation. Sucrose addition increased the abundances of enchytraeids and tardigrades and soil moisture percentage in the clear-cut areas. Sucrose also increased nematode abundance in the non-fertilized plots. Sucrose reduced the pool of waterextractable NH4-N in the soil in the first year, but increased it in the second year. Sucrose addition did not affect the decomposition rate of cellulose strips. The biomass of ground vegetation was not affected by sucrose. Carbohydrate addition seems…
Detection of Immunoglobulin Heavy Chain Gene Clonality By High-Throughput Sequencing for Minimal Residual Disease Monitoring in Chronic Lymphocytic L…
2019
Introduction: The negative minimal residual disease (MRD) after treatment has been recently accepted as endpoint for Chronic Lymphocytic Leukaemia (CLL) clinical trials. Conventionally, MRD can be detected by using multi-color Flow Cytometry (FC) with high sensitivity. Determination of the clonal immunoglobulin gene rearrangement can be a useful monitoring marker in a broad range of B-cell lymphoproliferative neoplasms. Moreover, the mutational status of immunoglobulin heavy chain variable (IgHV) rearrangement is considered one of the most important prognostic factors in CLL. Therefore, the identification of the IgHV rearrangement can be a useful marker both at diagnostic and as monitoring …
