    The incompatible interaction between plant and pathogen is often determined by the hypersensitive reaction (HR). This response is associated with accumulation of reactive oxygen species (ROS), which results in adverse growth conditions for pathogens. Two major mechanisms involving either NADPH oxidases or peroxidases have been proposed for generation of ROS. Peroxidases (PER, EC 1.11.1.7), present in all land plants, are members of a large multigenic family with high number of isoforms involved in a broad range of physiological processes. PER genes, which are expressed in nematode feeding sites, have been identified in several plant species (Zacheo et al. 1997). A strong correlation between HR and PER activities at four and seven days post nematode infection, was detected in roots of wheat lines carrying Cre2, Cre5 (from Ae. ventricosa) or Cre7 (from Ae. triuncialis) Heterodera avenae resistance genes (Andrés et al. 2001; Montes et al. 2003, 2004). We have studied changes in root of peroxidase mRNAs levels after infection by H. avenae of a wheat/Ae. ven¬tricosa introgression line (H-93-8) carrying Cre2 (Delibes et al. 1993). We also report and classify the predicted protein sequences derived from complete peroxidase transcripts

    The PDZ-adaptor protein syntenin-1 regulates HIV-1 entry

    Syntenin-1 is a cytosolic adaptor protein involved in several cellular processes requiring polarization. Human immunodeficiency virus type 1 (HIV-1) attachment to target CD4(+) T-cells induces polarization of the viral receptor and coreceptor, CD4/CXCR4, and cellular structures toward the virus contact area, and triggers local actin polymerization and phosphatidylinositol 4,5-bisphosphate (PIP(2)) production, which are needed for successful HIV infection. We show that syntenin-1 is recruited to the plasma membrane during HIV-1 attachment and associates with CD4, the main HIV-1 receptor. Syntenin-1 overexpression inhibits HIV-1 production and HIV-mediated cell fusion, while syntenin depletion specifically increases HIV-1 entry. Down-regulation of syntenin-1 expression reduces F-actin polymerization in response to HIV-1. Moreover, HIV-induced PIP(2) accumulation is increased in syntenin-1–depleted cells. Once the virus has entered the target cell, syntenin-1 polarization toward the viral nucleocapsid is lost, suggesting a spatiotemporal regulatory role of syntenin-1 in actin remodeling, PIP(2) production, and the dynamics of HIV-1 entry

    Parallel Implementation Strategies for MIMO ID-BICM Systems

    Full text link
    [EN] One of the current techniques proposed for multiple transmit and receive antennas wireless communication systems is the use of error control coding and iterative detection and decoding at the receiver. These sophisticated techniques produce a significant increase of the computational cost and require large computational power. The use of modern computer facilities as multicore and multi-GPU (Graphics Processing Unit) processors can decrease the computational time required, representing a promising solution for the receiver implementation in these systems. In this paper we explain how iterative receivers can improve the performance of suboptimal detectors. We also introduce a novel parallel receiver scheme based on a hybrid computing model where CPUs and GPUs work together to accelerate the detection and decoding steps; this design comes to exploit the features of the GPU NVIDIA Kepler architecture respect to the previous one in order to optimize the communication system performance.This work has been partially funded by PROMETEO/2009/013 project of Generalitat Valenciana, projects TEC2009-13741 of the Ministerio Español de Ciencia e Innovación, TEC2012-38142-C04 of the Ministerio Español de Economía y Competitividad, and PAID-05-2011 of Universitat Politècnica de València.Simarro Haro, MDLA.; Ramiro Sánchez, C.; Martínez Zaldívar, FJ.; Vidal Maciá, AM.; González Téllez, A.; Piñero Sipán, MG.; García Mollá, VM.

    Interferon lambda 3 (IFNL3, previously called IL-28B) is a cytokine with effects against viral and bacterial pathogens. We aimed to analyze the IFNL3 rs12980275 SNP in patients who underwent major surgery, in order to establish its relationship with susceptibility to septic shock and septic shock-related death in these patients. We performed a case-control study on 376 patients to establish the association between IFNL3 rs12980275 SNP and the susceptibility to develop septic shock. Besides, we performed a longitudinal study among 172 septic shock patients using survival analysis with one censoring point of 28-days mortality. The IFNL3 rs12980275 polymorphism was genotyped by Agena Bioscience's MassARRAY platform. IFNL3 rs12980275 polymorphism was not associated with higher susceptibility to infection and septic shock development. Regarding survival analysis, the Kaplan-Meier analysis showed that patients with IFNL3 rs12980275 AA genotype had higher survival than patients with GG genotype (p = 0.003). The Cox regression analysis adjusted by the most relevant clinical and epidemiological characteristics showed that the GG genotype (recessive model) and the presence of the G allele (additive model) were associated with higher risk of death [adjusted hazard ratio (aHR) = 2.15, p = 0.034; aHR = 1.50, p = 0.030, respectively]. In conclusion, IFNL3 rs12980275 polymorphism was associated with septic shock-related death in patients who underwent major surgery. The A allele was linked to protection, and the G allele was associated with an increased risk of death. This is a first preliminary study that suggests for the first time a role of IFNL3 polymorphisms in the prognosis of septic shock.This work has been supported by grants given by Instituto de Salud Carlos III (grant numbers PI15/01451 to ET), Gerencia de Salud, Consejería de Sanidad, Junta de Castilla y Leon (grant number GRS 463/A/10 and 773/A/13 to ET), and PFIZER (grant number CT25-ESP01-01 to SR).

    We carried out a retrospective exploratory study on 173 patients who underwent major surgery and developed septic shock after surgery. Our findings suggest that CEACAM7 rs1001578, rs10409040, and rs889365 polymorphisms could influence septic shock-related death in individuals who underwent major surgery.This work has been supported by grants given by Instituto de Salud Carlos III (grant number PI15/01451 to ET), “Gerencia de Salud, Consejería de Sanidad, Junta de Castilla y Leon” [grant number GRS 463/A/10 and 773/A/13 to ET], and PFIZER [grant number CT25-ESP01-01 to SR].

    El objetivo fue comparar entre géneros los efectos de un programa de actividad física moderada a vigorosa en escolares de 9 a 11 años de edad. Se diseñó un estudio cuantitativo, de nivel explicativo, y alcance experimental, prospectivo, longitudinal. Muestra intencionada de 57 estudiantes de una Escuela Primaria de Durango, México. La mayoría de participantes fueron mujeres. Edades entre 9 a 11 años (M = 10.18 años,  0.78). Padres de participantes firmaron consentimiento informado. Se aplicó programa de entrenamiento físico de cargas moderadas/vigorosas durante 12 semanas, frecuenca de tres sesiones semanales de 50 minutos por sesión. Se aplicaron evaluaciones pre-post intervención de potencia muscular abdominal, resistencia muscular brazos/pectorales, velocidad de desplazamiento, capacidad aeróbica (VO2Max). Para analizar resultados se utilizó prueba T-Student o Wilcoxon según existiera normalidad de los datos determinada con la prueba Kolmogorov-Smirnov. Los resultados advierten en las cuatro pruebas físicas mejores resultados pretest en los chicos. Las chicas obtuvieron mejores resultados en potencia muscular abdominal y velocidad de desplazamiento en postest, los chicos en resistencia muscular brazos/pectorales y capacidad aeróbica. Las chicas obtuvieron mayor adaptación física evidenciada en las diferencias medias pretest-postest. Se concluye que mismo entrenamiento aplicado en chicos y chicas genera mayor efecto en la condición física de ellas acortando diferencias entre sexos en el rendimiento físico. Diferencias físicas entre sexos podrían disminuir con estimulación física intencionada.  The purpose was to compare the effects of a moderate to vigorous physical activity program between genders in schoolchildren aged 9 to 11 years. A quantitative, explanatory, and experimental, prospective, longitudinal study was designed. The sample was intended for 57 students from an Elementary School in Durango, Mexico. The participants were mostly women. The age was between 9 and 11 years old (M = 10.18 years,  0.78). Participant´s parents signed an informed consent. A moderate to vigorous physical load training program was applied for 12 weeks, with a three sessions per week frequency and lasting 50 minutes per session. Pre-post intervention evaluations were applied measuring abdominal muscle power, arm/pectoral muscle endurance, travel speed, and maximum aerobic resistance (VO2Max).  The results analysis was performed the T-Student or Wilcoxon test according to the normality of the data determined with the Kolmogorov-Smirnov test. The results warn in the four physical tests applied best results in the pretest in boys. The girls got better results in abdominal muscle power and postest travel speed, boys in arm/pectoral muscle endurance and maximum aerobic endurance. The girls gained greater physical adaptation evidenced in the differences in pretest-postest stockings. Concludes that the same training applied in boys and girls generates greater effect on their physical condition by shortening the differences between sexes in physical performance. Physical differences between sexes may decrease with intentional physical stimulation
