Introduction: Sugarcane is an essential agricultural product for bioethanol production in Mexico. The discovery of both the bacterial community associated with this crop and the soil status is a decisive step towards understanding how microorganisms influence crop productivity. Culture enrichment allows for the identification of the biodiversity of biological samples. The objective of this research was to identify the bacterial biodiversity related with two complex carbohydrate sources (starch and cellulose) in soils sown with sugarcane in the Papaloapan Basin in Oaxaca, Mexico via a metagenomic approach. Method: Soil content was analyzed chemically. Liquid LB, LB-starch and LB-1% carboximetilcellulose media were inoculated with 2 g soil and cultured at 180 rpm, 37°C for 48 h. The biomass was collected and the 16S rDNA gene was amplified and a library was constructed which was analyzed by sequencing.Results: N, K and Zn content of organic matter showed higher values than average, as opposed to P and Na, which were lower than average. In the library, 35 OTUs related to Clostridium, Bacillus, Enterococcus, Lysinibacillus and Citrobacter genera were found which could contain genes for breaking cellulose and starch.Discussion or Conclusion: This is the first approach to identify the diversity related to starch and cellulose hydrolysis in the Papaloapan region, where the principal genera detected were Clostridium, Bacillus, Enterococcus, Citrobacter and Lysinibacillus in a soil moderately rich in organic matter.
Reordering edges and elements in unstructured meshes to reduce execution time in Finite Element Computations

Reverse Cuthill McKee (RCM) reordering can be applied to either edges or elements of unstructured meshes (triangular/tetrahedral) , in accordance to the respective finite element formulation, to reduce the bandwidth of stiffness matrices . Grid generators are mainly designed for nodal based finite elements. Their output is a list of nodes (2d or 3d) and an array describing element connectivity, be it triangles or tetrahedra. However, for edge-defined finite element formulations a numbering of the edges is required. Observations are reported for Triangle/Tetgen Delaunay grid generators and for the sparse structure of the assembled matrices in both edge- and element-defined formulations. The RCM is a renumbering algorithm traditionally applied to the nodal graph of the mesh. Thus, in order to apply this renumbering to either the edges or the elements of the respective finite element formulation, graphs of the mesh were generated. Significant bandwidth reduction was obtained. This translates to reduction in the execution effort of the sparse-matrix-times-vector product. Compressed Sparse Row format was adopted and the matrix-times-vector product was implemented in an OpenMp parallel routine.

Published: May 2018

Introducción: Las oleorresinas son extractos de naturaleza oleosa proveniente de los chiles, utilizadas como ingredientes para aportar sabor y aroma a muchos productos alimentarios. Sin embargo, son termolábiles y muy susceptibles a pérdidas de calidad durante el procesamiento o almacenamiento, siendo conveniente encapsular sus componentes bioactivos antes de ser utilizados como ingredientes alimentarios con la finalidad de que no se vea afectada su vida útil.Método: Oleorresina del chile habanero (OCH) fue encapsulada utilizando la técnica de inclusión molecular con β-ciclodextrina (βCD) para protegerla durante su almacenamiento. El complejo de inclusión molecular (OCH-βCD) se preparó en las proporciones 20:80 y 30:70 de oleorresina: β-ciclodextrina respectivamente, y fueron almacenadas por 5 semanas en un rango de actividad de agua (aw) de 0.103-0.765, a una temperatura de 25, 35 y 45 °C. Se realizó el estudio de las propiedades termodinámicas para explicar el efecto de la temperatura y la aw sobre la estabilidad de los encapsulados.Resultados: Los resultados mostraron que el complejo de inclusión en la proporción 30-70 es más estable que el elaborado en la proporción 20-80, al ser menos higroscópico, presentar una amplia zona de mínima entropía integral de alrededor de una aw de 0.3-0.6 y menores valores del parámetro (ΔE) durante el almacenamiento a 25 ºC. Discusión o Conclusión: De acuerdo con los análisis termodinámicos y las pruebas de la variación de DE, fue posible obtener la proporción adecuada de encapsulación (OCH-bCD), asi como recomendar las mejores condiciones de temperatura y humedad durante el almacenamiento, para evitar cambios drásticos en el color, producto de la degradación térmica de los carotenoides presentes en las muestras.

El gobierno federal a través de la Dirección General de Zonas Tropicales de la Secretaría de Agricultura, Ganadería, Desarrollo Rural, Pesca y Alimentación (SAGARPA), ha venido im-pulsando la apertura de 20,000 ha del cultivo de café robusta en los estados del sur-sureste. Como parte de esa iniciativa se realiza el presente estudio para determinar en qué áreas del estado de Tabasco este tipo de café puede prosperar exitosamente y cuáles serían los impactos del cambio climático a mitad del siglo XXI, en su adaptación y rendimiento. Así, el objetivo del presente estudio fue: determinar las mejores áreas desde el punto de vista de clima y suelo, para cultivar café tipo robusta (Coffea canephora P.) en el estado de Tabasco y su posible vulnerabilidad al cambio climático a mediados del presente siglo.Método: Lo anterior se realizó utilizando la metodología de Zonificación Agro-Ecológica (ZAE) pro-puesta por la FAO para las condiciones actúales y para el escenario de cambio climático (RCP8.5), esperado a mediados del siglo XXI.Asimismo, se estimaron los rendimientos potenciales para tres niveles de insumo (bajo, medio y alto) en las áreas resultantes muy aptas, para ambas condiciones climáticas, utilizando el método de Zonas Agro-Ecológicas (ZAE) propuesto por la FAO (1981) y actualizado por Fischer et al. (2012).Resultados: Los resultados indican que de ocurrir un incremento promedio diario de 1.6 ºC para el año 2050, bajo el peor escenario (RCP8.5), la superficie muy apta para cultivar café tipo robusta en el estado de Tabasco no se modifica. En cambio, los rendimientos potenciales promedio disminuirán en 41% para el año 2050, debido al efecto del incremento de las temperaturas diurnas sobre la tasa fotosintética máxima.Discusión: En el estado de Tabasco existen actualmente 154,755.14 ha edafoclimáticamente muy aptas para establecer el cultivo de café tipo robusta. Bajo el escenario de cambio climático A2 (RCP8.5) se espera un incremento en la temperatura promedio diaria de 1.6 ºC, la cual no afectará la aptitud edafoclimática del café robusta. Los rendimientos potenciales promedio varían en función del nivel de insumos para la edad y densidad de siembra señalada.

Published: May 2018

Introduction: The data available regarding the chemical composition and procedures for the extraction of the propolis are currently inconclusive. In this study the chemical groups present in the extracts of a propolis mixture obtained by different methods were identified. Additionally, their content of polyphenols and flavonoids was determined, and antioxidant and antibacterial activity was studied. Method: The extracts were obtained by maceration and for the ultrasonic and microwave method. Phenolic and flavonoid compounds, as well as the measurement of antioxidant activity, were quantified by spectrophotometric methods. The antibacterial activity was studied from the inhibitory effect of each extract against Escherichia coli, Salmonella typhi, Staphylococcus aureus and Proteus mirabilis, and by the percentage of activity and the Index of Bacterial Susceptibility (IBS). Results: The phytochemical screening evidenced the presence of abundant compounds with important biological activity. It was found a significant difference (p < 0.05) in the antioxidant and antimicrobial activity of the extracts of propolis obtained by different methods. Conclusion: The presence of chemical groups of bioactive compounds and their antioxidant and antibacterial activity justifies the use of these extracts in traditional medicine.

Published: May 2018

Background:
Abnormal amyloid β (Aβ) accumulation and deposition in the hippocampus is
an essential process in Alzheimer’s disease (AD).

Objective:
To investigate whether Oleanolic acid (OA) could improve memory deficit in AD model
and its possible mechanism.

Methods:
Forty-five SD rats were randomly divided into sham operation group, model group, and OA
group. AD models by injection of Aβ25-35 were built. Morris water maze (MWM) was applied to investigate
learning and memory, transmission electron microscope (TEM) to observe the ultrastructure of
synapse, western blot to the proteins, electrophysiology for long-term potentiation (LTP), and Ca2+
concentration in synapse was also measured.

Results:
The latency time in model group was significantly longer than that in sham operation group
(P=0.0001); while it was significantly shorter in the OA group than that in model group (P=0.0001);
compared with model group, the times of cross-platform in OA group significantly increased
(P=0.0001). TEM results showed OA could alleviate neuron damage and synapses changes induced by
Aβ25-35. The expressions of CaMKII, PKC, NMDAR2B, BDNF, TrkB, and CREB protein were significantly
improved by OA (P=0.0001, 0.036, 0.041, 0.0001, 0.0001, 0.026, respectively) compared
with that in model group; the concentration of Ca2+ was significantly lower in OA group (1.11±0.42)
than that in model group (1.68±0.18); and the slope rate (P=0.0001) and amplitude (P=0.0001) of f-
EPSP significantly increased in OA group.

Conclusion:
The present results support that OA could ameliorate Aβ-induced memory loss of AD
rats by maintaining synaptic plasticity of the hippocampus.

Published: May 2018

Background
Researchers are increasingly interested in testing and developing computerized cognitive training interventions for individuals with autism spectrum disorder due to the limited accessibility of treatments for this disorder. Understanding the feasibility of testing cognitive interventions for this population is critical, especially for individuals with ASD who have low to moderate intellectual ability.

Objective
The aim of the study was to evaluate the feasibility of computerized cognitive training as measured by attrition rate and a parent satisfaction survey.

Methods
A total of 26 participants aged 8-17 years with an autism spectrum disorder diagnosis and significant intellectual impairment were enrolled (mean age 11.1 years). They were instructed to complete 25 sessions of Cogmed Working Memory Training in 5 to 6 weeks with coach assistance. Attrition rate and parent satisfaction surveys were measured after the completion of training.

Results
Most participants (96%, 25/26) completed the training and indicated high satisfaction (>88%). However, among the participants who completed the training, 5 participants (19%) were unable to finish in 6 weeks, the recommended training period by Cogmed. Parents noted various positive (eg, voice-overs) and negative (eg, particular graphic and sounds associated with a stimulus) features of the game that they thought affected their child’s response.

Conclusions
Children with autism spectrum disorder and intellectual impairments can successfully participate in computerized cognitive training interventions but may require additional weeks to complete the training beyond the time needed for children without intellectual impairments. The overall completion rate, with extended time to complete the training, was high. Developers of cognitive training programs for this population should take into account potential issues regarding the noise level of stimuli and characteristics of the visual graphics.
Three-dimensional treatment planning for maxillary and mandibular segmental surgery for an adult Class III: Where old meets new
Authors: Conley R. Scott , Edwards Sean P. 
Published: May 2018

ABSTRACT
Class III open bite malocclusion can be among the most difficult case types to obtain an excellent occlusal, skeletal, and facial outcome. Treatment options include growth modification, extraction for orthodontic camouflage, and orthognathic surgery. For the most severely affected and non-growing patients, orthognathic surgery is often the most predictable and, in some situations, the only viable way of achieving an optimal result. The risks and benefits of surgical treatment options can occasionally be difficult to assess particularly for providers with limited experience. Two-dimensional surgical predictions can assist but do not permit the third dimension to be visualized. New techniques of computer-aided surgical simulation can enable the surgeon, orthodontist, and patient to better visualize and understand the treatment approach and enable them to make the most effective and efficient treatment related decisions. This case merges knowledge of the full spectrum of historical surgical techniques with the new approach of computer-aided surgical simulation (CASS) to perform complex segmental maxillary and mandibular surgery to obtain an excellent functional and esthetic result.

Archaeolinguistics As A Way To Overcome The Impasse In Comparative Linguistics
Authors: Kozyrski Wolodymyr Hlib , Malovichko Alexander Victor 
Published: May 2018

The paper exposes some essential points of our one and a half decade research results within new approach to study prehistoric stages of human language development mainly in times of ergaster-erectus domination and reflects our reaction to the protracted conceptual crisis in the comparative linguistics. As a result of fundamentally incorrectly stated goals, most of the researchers artificially limited themselves both by the defined scope of the problems to solve and by the methods used. Becoming tightly tied knot of up to now unsolved intrinsic contradictions, today comparative linguistics needs radical change. We have developed a synthetic approach that has proved its effectiveness. Our model is well aligned with prehistoric data of auxiliary historical disciplines and even IBM Genographic project. The results offer further opportunities for interesting studies.
