Effect of size and composition on the second harmonic generation from lithium niobate powders at different excitation wavelengths

INVESTIGACIÓN DESARROLLADA EN COLABORACIÓN DE RED TEMATICA PRODEP /SEP/MEXICOLiNbO3 microcrystalline systems, possessing almost stoichiometric composition, were produced by varying the temperature and time parameters in the annealing processes following a mechanochemical reaction of raw powders. SHG from these samples, detected for every fundamental wavelength in the range 800-1300 nm, and being maximal at a certain wavelength, λmax, for each sample, has been addressed to a random scattering of the induced nonlinear polarizations. Possible tuning of λmax could be ascribed to control of composition and grain size of the sample. Random orientation of the produced nanocrystallites was verified since no dependence for SHG intensity on incident polarization was observed.PAPIIT-UNAM through grant IN117116 Y “RED PRODEP-SEP Compuestos poliméricos propiedades y aplicaciones 2015-2016

Caracterización de las fracturas supracondíleas del húmero en niños que requirieron manejo quirúrgico en un hospital de Santander, Colombia

Introducción. El objetivo del estudio fue describir las características sociodemográficas, tratamiento y complicaciones pre y posquirúrgicas de las fracturas supracondíleas del húmero distal en niños que requirieron manejo quirúrgico en un hospital de Santander, Colombia. Metodología. Se trata de un estudio observacional, descriptivo, de corte transversal con 58 pacientes que cumplieron los siguientes criterios de inclusión: edad entre 3 a 14 años, fracturas supracondíleas de manejo quirúrgico; como criterios de exclusión se tomó: antecedente de enfermedad ósea o neurológica previa y fracturas de más de 7 días de evolución. Para las variables continuas se usó medidas de tendencia central y dispersión, las categóricas en porcentajes y frecuencias absolutas. Resultados. La edad media de presentación fue de 6.2 años, el principal mecanismo de trauma fue caídas de altura con un 96.5%. El 65.5% provenía de zonas urbanas. El 13.8% se asoció con fracturas de antebrazo, y el 3.4% de epitróclea. La fijación se realizó en un 75% con técnica cruzada y un 17.2% se asoció con lesión iatrogénica del nervio ulnar. Discusión. En el estudio no se informaron lesiones vasculares; sin embargo, se documentó una alta prevalencia de lesión neurológica con la fijación medial, similar a lo descrito en la literatura (1.4%-17.7%); algunos autores describen técnicas que disminuyen estas lesiones hasta en un 0%. Conclusión. Las características sociodemográficas de nuestra población coinciden con la estadística publicada mundialmente; la principal complicación fue la lesión iatrogénica nervio ulnar, que se puede disminuir con un uso racional del pin medial y con el empleo de técnicas que busquen rechazar directamente el nervio. Introduction. The objective of this study was to describe sociodemographic characteristic, treatment, and pre- and post-surgical complications of supracondylar fractures of the distal humerus in children who required surgical management at a hospital in Santander, Colombia. Methodology. This was an observational, descriptive, and cross-sectional study involving 58 patients who met inclusion criteria: age between 3 and 14 years old, supracondylar fractures with surgical management; exclusion criteria include previous bone or neurological illness and fractures with more than 7 days of evolution. Central tendency and dispersion measures were used for continuous variables, and categorical variables in percentages and absolute frequencies. Results. The average age at presentation was 6.2 years old, the main mechanism of trauma was fall from height (96.5%). 65.5% came from urban zones. The 13.8 % were associated with forearm fractures, and 3.4% with epitrochlear fractures. Pinning was performed at 75% with crossed technique and 17.2% were associated with iatrogenic ulnar nerve injury. Discussion. Study didn’t inform vascular injuries. However, a high prevalence of neurological injury with medial pinning was documented, similar to that describe in the literature (1.4%-17.7%); some author described techniques that reduce these lesions by 0%. Conclusion. The sociodemographic characteristics of our population match with worldwide published statistics; the main complication was iatrogenic ulnar nerve injury, which can be reduced with the rational use of medial pin and with the application of techniques that seek to directly spare the nerve.

Health outcomes among HIV-positive Latinos initiating antiretroviral therapy in North America versus Central and South America

Introduction: Latinos living with HIV in the Americas share a common ethnic and cultural heritage. In North America, Latinos have a relatively high rate of new HIV infections but lower rates of engagement at all stages of the care continuum, whereas in Latin America antiretroviral therapy (ART) services continue to expand to meet treatment needs. In this analysis, we compare HIV treatment outcomes between Latinos receiving ART in North America versus Latin America. Methods: HIV-positive adults initiating ART at Caribbean, Central and South America Network for HIV (CCASAnet) sites were compared to Latino patients (based on country of origin or ethnic identity) starting treatment at North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) sites in the United States and Canada between 2000 and 2011. Cox proportional hazards models compared mortality, treatment interruption, antiretroviral regimen change, virologic failure and loss to follow-up between cohorts. Results: The study included 8400 CCASAnet and 2786 NA-ACCORD patients initiating ART. CCASAnet patients were younger (median 35 vs. 37 years), more likely to be female (27% vs. 20%) and had lower nadir CD4 count (median 148 vs. 195 cells/µL, p<0.001 for all). In multivariable analyses, CCASAnet patients had a higher risk of mortality after ART initiation (adjusted hazard ratio (AHR) 1.61; 95% confidence interval (CI): 1.32 to 1.96), particularly during the first year, but a lower hazard of treatment interruption (AHR: 0.46; 95% CI: 0.42 to 0.50), change to second-line ART (AHR: 0.56; 95% CI: 0.51 to 0.62) and virologic failure (AHR: 0.52; 95% CI: 0.48 to 0.57). Conclusions: HIV-positive Latinos initiating ART in Latin America have greater continuity of treatment but are at higher risk of death than Latinos in North America. Factors underlying these differences, such as HIV testing, linkage and access to care, warrant further investigation

Using human behavior to develop knowledge-based virtual organizations

Virtual organizations promote dynamic interaction between individuals, groups, and organizations, who share their capabilities and resources to pursue a common goal and maximize their benefits. Among these resources, knowledge is a critical one that requires special attention in order to support problem-solving activities and decision-making processes and provide strategic advantage. This article presents an initial proposal for the creation of dynamic knowledge-based virtual organizations, as a way to share knowledge in order to support problem-solving activities. This approach is based on behavioral elements, identified by other researchers, that affect group interactions; these items are represented inside the e-decisional community in a manner that allows software agents to interact similarly to their human counterparts. An initial model and a functional prototype have been developed and used to obtain a set of preliminary results, which show human-like behavior in our test system

Protein biosynthesis in trypanosomidae. II. The metabolic fate of dl-leucine-1-C14 in Trypanosoma cruzi

Protein biosynthesis in trypanosomidae. II. The metabolic fate of dl-leucine-1-C14 in Trypanosoma cruzi. Experimental Parasitology 21, 154-159. Trypanosoma cruzi is able to metabolize dl-leucine-1-C14 incorporating its radioactivity into various metabolic fractions. Utilization of leucine is higher in the presence of glucose than in its absence. Both substrates are metabolized individually or together as shown by the respiratory CO2 production. The path of leucine catabolism seems to be similar to that which has already been described for mammals. Leucine seems also to enter the Krebs cycle and possibly other alternative pathways since glycolic acid is produced with other nonvolatile acids and, thus, indicates the possibility of the glyoxylate shunt. Antibiotics do not affect the metabolism of leucine, with the exception of that which is concerned with its incorporation into proteins. © 1967

Smart knowledge-sharing platform for e-decisional community

Knowledge plays a major role in enterprises, given its importance as a significant organizational asset. In order to solve problems and support complex decision-making processes, knowledge and experience have to be transmitted between diverse individuals and organizations. Thus, knowledge-sharing can be considered a fundamental element in any knowledge-oriented process, because it fosters collaboration, and facilitates experiential knowledge discovery, distribution, and use. We present the E-Decisional Community, a proposal for an integrated knowledge-sharing platform where several entities are able to share experiential knowledge. Its main concern is to promote experiential knowledge evolution and sharing through generations of decision makers, aiming at the creation of a marketplace where knowledge is provided as a service
