Authors: Rosales-Solórzano Emer-Ronald 
Published: February 2020

La escasa información en estudios físicos de la madera hicieron realizar ensayos en 10 especies forestales representativas para determinar ecuaciones matemáticas, además se seleccionaron otras 95 especies donde se aplicaron, probaron y validaron los modelos para el contenido de humedad equilibrio (CHE), contenido de humedad libre (CHL), punto de saturación de las fibras (PSF) y contenido de humedad máxima (CHM) de la madera, usando el método de medición instantánea previa saturación en agua caliente a 100 °C por 24 horas y secado en estufa. La densidad básica (DB) varió de 0,27 a 0,92 g/cm3, rango donde se ubica el CHM medido que cambió de 49 a 302 %, mientras que el ajustado tuvo un comportamiento exponencial igual a CHM = 597,96e-2,843DB que varió de 44 a 281 %. El CHL estimado cambió de 31 a 234 % y el ajustado presentó un comportamiento exponencial igual a CHL = 583,84e-3,263DB que cambió de 29 a 245 %. El PSF estimado promedio fue 27 % variando de 18 a 68 % y el ajustado exhibió un comportamiento potencial igual a PSF = 14,678DB-0,83 que varió de 16 a 44 %. El CHE medido promedio fue 12,63 % variando de 9 a 16 % y el ajustado tuvo un comportamiento logarítmico igual a CHE = - 4,141ln (DB) + 9,8939 que cambió de 10 a 15 %. Los modelos generados predijeron los niveles de humedad con un coeficiente de correlación (r) muy alta en CHM y CHL igual a r = 0,991, alta en el PSF de r = 0,828 y CHE con r = 0,851.

Published: February 2020

El objetivo de la investigación fue informar sobre los efectos del densificado por compresión mecánica en maderas de Cedrela odorata, Cupressus lindleyi, Swietenia macrophylla, Dalbergia paloescrito, Tabebuia donnell-smithii, Fraxinus uhdei, Fagus mexicana y Guazuma ulmifolia. Las variables de respuesta fueron la densidad y el módulo dinámico, que fue determinado con vibraciones transversales. Ambos parámetros se midieron antes y después del tratamiento. El coeficiente de densificado fue, en promedio, de 30 % y similar entre especies. Tanto las densidades como los módulos dinámicos aumentaron como efecto del densificado. Esta ganancia tecnológica es particular a cada especie. Si bien los resultados están restringidos a las especies densificadas en esta investigación, sugieren una mejora en estas características físico-mecánicas que son importantes para el diseño y cálculo de productos y estructuras de madera. Para mejorar el tratamiento se recomiendan estudios sobre los cambios en la anatomía de la madera y en sus propiedades físicas.

Increased electrical conductivity dispersion -hardened copper
Authors: Lovshenko F. G. , Khabibulin A. I. 
Published: February 2020

The material, obtained in reactor, is a composition, consisting of a copper matrix of microcrystalline type with the borders of grains, stabilized by disperse particles of strengthening phases in the size of less than 20 nanometers. It is established, that the application of oxide nitrogen N2O as the technological environment at mix material processing in reactor activates the oxidationreduction transformations, which take place in mechanically alloyed compositions on the basis of system Cu–Al–CuO–MoO3, that leads to decrease in concentration of aluminium in a copper-based solid solution and, as a consequence, increases electrical conductivity of the material by 14 %, reaching values of 80 % from electrical conductivity of copper. It is shown, that the developed material is characterized by high stability against long thermal influence at the temperatures, reaching 0, 85 of temperatures of a basis fusion, which is explained by its structure.
Natural Bridge, Virginia: Complementary Geotechnical Investigation and Analysis Methods for Mobility Planning
Authors: Bruckno Brian S. , Watts Chester F. , Stephenson George , Mau Christopher 
Published: February 2020

ABSTRACT
Natural Bridge, in Rockbridge County, Virginia, is a geological arch carrying U.S. Route 11 over Cedar Creek. The area has significant historical and cultural importance; it is listed on the National Register of Historic Places and is a Virginia Historic Landmark. Until 2015, the arch and area below were privately owned and operated, with only the pavement structure of U.S. Route 11 held by the Virginia Department of Transportation. Since then, the arch and area below have been leased to the Virginia Department of Conservation and Recreation, potentially transferring liability to the Commonwealth. As part of the Commonwealth's due diligence and to help ensure that the arch is preserved for future generations, the Department of Transportation, in partnership with Radford University, completed a comprehensive, non-invasive geological and geotechnical investigation in 2017 and 2018. A complementary variety of geophysical, laser, optical, seismic, and traditional geological methods of study were used to allow for integrated data analysis. The investigation revealed potential risks to the integrity of the arch, which may eventually reduce its suitability for use as a transportation corridor. The investigation methodology allowed planning for protection of the environment, cultural resources, and local economies while avoiding any potential damage to the arch. As of the date of this article, plans are under way to relocate U.S. Route 11 onto an alternate alignment entirely, thereby helping to preserve this valuable cultural, historical, and geological asset.
Increased expression of SLC35F2 in non-small cell lung cancer predicts poor prognosis
Authors: Wei Peng , Huang Zhenjie , Liu Guangnan 
Published: February 2020

Abstract
Background: Although previous studies have documented the expression of Homo sapiens solute carrier family 35 member F2 (SLC35F2) in NSCLC, its prognostic value for NSCLC has not been reported.Methods: We performed Wilcoxon signed-rank test and logistic regression to investigate the correlations between SLC35F2 expression and clinical parameters. A Cox regression was used to investigate the association between clinical features and overall survival (OS). Gene Set Enrichment Analysis (GSEA) was performed to further understand the pathways involved in NSCLC pathogenesis related SLC35F2.Results: In LUAD, increased expression of SLC35F2 was associated with stage (OR = 1.53 for stage III-IV vs. Stage I-II), N stage (OR = 1.62 for N1-3 vs. N0), and residual tumor (OR = 5.00 for with tumor vs. Tumor free) (p <0.05). The Kaplan-Meier curve showed that the prognosis of SLC35F2-high NSCLC was worse than that of SLC35F2-low. For LUAD, the univariate analysis showed that increased expression of SLC35F2 was associated with a poor overall survival (HR 1.04; 95% CI 1.00-1.08; p = 0.04). Multivariate analysis showed that SLC35F2 can be used as an independent prognostic factor for LUAD. GSEA show that P53 signal pathway and apoptosis are signiﬁcantly enriched in SLC35F2-high in NSCLC.Conclusions: Increased expression of SLC35F2 in non-small cell lung cancer predicts poor prognosis. Moreover, SLC35F2 can be used as an independent prognostic factor for LUAD.
Current Evidence of Mesenchymal Stem Cells Use in the Treatment of Tendon Disorders: A Systematic Review, Meta-analysis, and Meta-regression of Prospective Clinical Studies

Published: February 2020

Abstract
Purpose: Although several studies with animals have reported the effects of mesenchymal stem cells (MSCs) for tendon regeneration, little is known about the efficacy and safety of MSCs in human tendon disorders. We performed this meta-analysis to evaluate the efficacy and safety of MSC therapy in patients with tendon disorders enrolled in prospective clinical studies.Methods: We systematically searched prospective clinical studies investigating the effects of MSCs administration on human tendon disorders with at least a 6-month follow-up period on PubMed-Medline, Embase, and Cochrane Library databases. The primary outcome of interest was the change in pain on motion related to tendon disorders. We performed a pairwise meta-analysis using the fixed-effects model to assess treatment response, which was calculated by the standardized mean difference. Meta-regression analyses were performed to assess the relationship between MSCs dose and pooled effect sizes in each cell dose.Results: Four prospective clinical trials investigating the effect of MSCs on tendon disorders were retrieved. MSCs showed significant pooled effect size (overall Hedge’s g pooled standardized mean difference (SMD) = 1.868; 95% confidence interval [CI], 1.274–2.462; P < 0.001). The treatment with MSCs improved all the aspects analyzed, i.e. pain, functional scores, radiologic parameters (magnetic resonance image or ultrasonography), and arthroscopic findings. In the meta-regression analysis, there was a significant cell dose-dependent response in pain relief (Q = 9.06, P = 0.029). While three studies reported mild adverse events after MSCs injection, these were not severe and relieved spontaneously.Conclusions: Our meta-analysis revealed that MSC therapy may improve pain, function, radiologic, and arthroscopic parameters in patients with tendon disorders. Due to the small number of studies in this meta-analysis and considering the increasing MSCs applications, there is a strong need for large-scale randomized controlled trials to confirm the long-term functional improvement as well as the adverse effects of MSC therapies in tendon disorders.

Abstract
Background: Atherosclerosis is mediated by various factors and plays an important pathological foundation for cardiovascular and cerebrovascular diseases. Abnormal VSMC proliferation and migration have an essential role in atherosclerotic lesion formation. Circular RNAs have been widely detected in different species and are closely related to various diseases. However, the expression profiles and molecular regulatory mechanisms of circRNAs in VSMCs are still unknown. Methods: We used high-throughput RNA-seq as well as bioinformatics tools to systematically analyze circRNA expression profiles in samples from different VSMC phenotypes. PCR, Sanger sequencing, and qRT-PCR were performed for circRNA validation. Results: A total of 22191 circRNAs corresponding to 6273 genes (host genes) in the PS, NC or both groups, were detected, and 112 differentially expressed circRNAs were identified between the PS and NC groups, of which 59 were upregulated and 53 were downregulated. We selected 9 circRNAs for evaluation of specific head-to-tail splicing, and 10 differentially expressed circRNAs between the two groups for qRT-PCR validation. Gene Ontology and KEGG pathway enrichment analyses revealed that the parental genes of the circRNAs mainly participated in cardiac myofibril assembly and positive regulation of DNA-templated transcription, indicating that they might be involved in cardiovascular diseases. Finally, we constructed a circRNA-miRNA network based on the dysregulated circRNAs and VSMC-related miRNAs. Conclusion: The current study is the first to show the differential expression of circRNAs in PDGF-BB-induced vascular smooth muscle cells and may provide new ideas and targets for the prevention and therapy of vascular diseases.
