Prompt photon yield and v2v_2 coefficient from gluon fusion induced by magnetic field in heavy-ion collision

We compute the production of prompt photons and the $v_2$ harmonic coefficient in relativistic heavy-ion collisions induced by gluon fusion in the presence of an intense magnetic field, during the early stages of the reaction. The calculations take into account several parameters which are relevant to the description of the experimental transverse momentum distribution, and elliptic flow for RHIC and LHC energies. The main imput is the strength of the magnetic field which varies in magnitude from 1 to 3 times the pion mass squared, and allows the gluon fusion that otherwise is forbidden in the absence of the field. The high gluon occupation number and the value of the saturation scale also play an important role in our calculation, as well as a flow velocity and geometrical factors. Our results support the idea that the origin of at least some of the photon excess observed in heavy-ion experiments may arise from magnetic field induced processes, and gives a good description of the experimental data.Comment: 6 pages, 2 figures, conference paper from ISMD 201

Objetivo: Comparar la apendicectomía laparoscópica de puerto único con la de 3 puertos en pacientes con apendicitis aguda, de los hospitales “Vicente Corral Moscoso” y “José Carrasco Arteaga” durante el primer semestre del año 2013. Materiales y método: Estudio experimental que incluyó 170 pacientes de emergencia de los hospitales “Vicente Corral Moscoso” y “José Carrasco Arteaga”; al 50% se le realizó apendicectomía con puerto único (grupo 1) y al restante, se le realizó apendicectomía con 3 puertos (grupo 2). Resultados: De 18 a 25 años fue el grupo mayormente afectado, el sexo masculino predominó en ambos grupos. El tiempo quirúrgico de 61 a 120 minutos fue 61.2% en el grupo 1, el grupo 2 del 55.3%. Dolor posoperatorio leve se presentó en el grupo 1 en 63.5% y en el grupo 2, 41.2%, estancia hospitalaria de 13 a 24 horas en grupo 1 de 62.4%, en el grupo 2, de 25 a 36 horas en 47.1%. Los resultados del puerto único para menor tiempo quirúrgico encontramos un RR de 0,71 (IC –95% 0.4-1.2), RRR 0.29, RAR 0,07 y NNT 15; para intensidad del dolor (leve) RR de 1.54 (IC 95% 1.1-2), RRR -0.54, RAR -0.22 y NNT 5 y para menor estancia hospitalaria (menor a 12 horas) RR = 3.5 de 0.71 (IC 95% 0.75-12.3), RRR -2.5, RAR 0.06 y NNT 17. Conclusión: La apendicectomía laparoscópica con puerto único presenta beneficio únicamente en la intensidad de dolor, en comparación con el acceso de 3 puertosObjective: To compare the single-port laparoscopic appendectomy with 3 ports surgery in patients with acute appendicitis from the hospitals “Vicente Corral Moscoso” and “José Carrasco Arteaga” during 2013. Materials and Methods: An experimental study was done in which were included 170 emergency patients from the hospitals “Vicente Corral Moscoso” and “José Carrasco Arteaga”; half of them, underwent the appendectomy with single port (group 1) and the other half underwent the appendectomy with 3 ports (group 2). Results: The most affected age group was between 18 and 25 years, and the male gender predominates in both groups. The operating time of 61-120 minutes was 61.2 % in group 1, in group 2 was 55.3 %. The mild pain postoperative was presented in group 1 in 63.5% and in group 2 was 41.2%, with a hospital stance of 13-24 hours in the group 1 with 62.4%. Meanwhile in group 2, about 25 to 36 hours with 47.1%. Analyzing the results of the single port with less surgical time, we found an RR of 0.71 (95% CI 0.4-1.2), RRR 0.29, NNT 15, RAR 0.07; for pain intensity (mild) RR of 1.54 (CI 95% 1.1-2), RRR -0.54, RAR -0.22 and NNT 5 and for shorter hospital stay (less than 12 hours) RR = 3.5 0.71 (95% CI 0.75 to 12.3) -2.5 RRR, NNT 17 RAR 0.06. Conclusion: The single port laparoscopic appendectomy has similar results with international research only on postoperative pain compared to 3 port access.Cuencavolumen 33 número

Promp photon yield and υ2 coefficent from gluon fusion induced by magnetic field in heavy-ion collisions

We compute the production of prompt photons and the υ2 harmonic coefficient in relativistic heavy-ion collisions induced by gluon fusion in the presence of an intense magnetic field, during the early stages of the reaction. The calculations take into account several parameters which are relevant to the description of the experimental transverse momentum distribution, and elliptic flow for RHIC and LHC energies. The main imput is the strenght of the magnetic field which varies in magnitude from 1 to 3 times the pion mass squared, and allows the gluon fusion that otherwise is forbidden in the absence of the field. The high gluon occupation number and the value of the saturation scale also play an important role in our calculation, as well as a flow velocity and geometrical factors.

Optimización del proceso de extracción asistida por ultrasonido de compuestos fenólicos de Justicia spicigera Schltdl. mediante la metodología de superficie de respuesta

The interest in the study of polyphenols has grown considerably in recent years due to its high capacity to scavenge free radicals associated with various diseases. For this reason, the aim of this work was to obtain and characterize phenolic compounds from Justicia spicigera Schltdl by ultrasound-assisted extraction. The extracts were characterized in terms of the total phenolic content (Folin-Ciocalteu method), antioxidant activity (ferric-reducing/antioxidant power) and free radical scavenging activity (2,2-diphenyl-1-picrylhydrazyl free radical method). The response surface methodology (RSM) was used to evaluate the effect of the solvent (water/ethanol) and the extraction time, on the total phenolic content and antioxidant properties. The analysis of variance (ANOVA) indicated that the concentration of water in the solvent mixture significantly affected the yield of the compounds, as well as the antioxidant and antiradical activities. According to the RSM, the optimal extraction conditions are 25% water in the solvent mixture and a sonication time of 16 min.El interés en el estudio de los polifenoles ha crecido de manera considerable en los últimos años debido a su alta capacidad para atrapar radicales libres asociados con diversas enfermedades. Por este motivo, el objetivo del presente trabajo fue obtener y caracterizar los compuestos fenólicos de Justicia spicigera Schltdl. mediante extracción asistida por ultrasonido. A los extractos, se les determinó el contenido fenólico total (método de Folin-Ciocalteu), actividad antioxidante (potencial antioxidante/reductor del hierro) y actividad secuestradora de radicales libres (método del radical libre 2,2-difenil-2-picrilhidrazil). La metodología de superficie de respuesta (MSR) se empleó para evaluar el efecto del disolvente (agua/etanol) y el tiempo de extracción, en el contenido de fenoles totales y las propiedades antioxidantes. El análisis de varianza (ANOVA) indicó que la concentración de agua en la mezcla del disolvente afectó de manera importante el rendimiento de los compuestos, así como la actividad antioxidante y antiradical. De acuerdo con la MSR, las condiciones óptimas para la extracción son 25% de agua en la mezcla del disolvente y un tiempo de sonicación de 16 minutos

Genomic Characterization by Whole-Exome Sequencing of Hypermobility Spectrum Disorder

No genetic basis is currently established that differentiates hypermobility spectrum disorders (HSD) from hypermobile Ehlers–Danlos syndrome (hEDS). Diagnosis is entirely based on clinical parameters with high overlap, leading to frequent misdiagnosis of these two phenotypes. This study presents a landscape of DNA mutations through whole-exome sequencing of patients clinically diagnosed with generalized HSD. In this study, three genes (MUC3A, RHBG, and ZNF717) were mutated in all five patients evaluated. The functional enrichment analysis on all 1162 mutated genes identified the extracellular matrix (ECM) structural constituent as the primary overrepresented molecular function. Ingenuity pathway analysis identified relevant bio-functions, such as the organization of ECM and hereditary connective tissue disorders. A comparison with the matrisome revealed 55 genes and highlighted MUC16 and FREM2. We also contrasted the list of mutated genes with those from a transcriptomic analysis on data from Gene Expression Omnibus, with only 0.5% of the genes at the intersection of both approaches supporting the hypothesis of two different diseases that inevitably share a common genetic background but are not the same. Potential biomarkers for HSD include the five genes presented. We conclude the study by describing five potential biomarkers and by highlighting the importance of genetic/genomic approaches that, combined with clinical data, may result in an accurate diagnosis and better treatment
