Variaciones de largo periodo de los tipos de tiempo de superficie en México
Authors: Jáuregui Ostos Ernesto
Published: August 2017

Se examinan las diversas clasificaciones de tipos de tiempo que se han hecho para México, basadas en la distribución de la presión al nivel del mar. Al consultar los tipos de tiempo para los periodos 1919–38, 1951–55 y 1961–66 se encontró que los tipos de invasión de aire polar acusan una variación entre 1919–66 muy semejante a la que se observa en la precipitación de algunos lugares de México. Al mismo tiempo estas oscilaciones coinciden con las observadas en el índice zonal de la corriente de los vientos del oeste en el Atlántico Norte. Los resultados anteriores confirman las conclusiones de Bradbury quien encontró que con una situación de índice alto se eleva en Norteamérica la incidencia de anticiclones en bajas latitudes durante el invierno.

Situaciones climáticas durante el auge y la caida de la cultura teotihuacana
Authors: García Enriqueta
Published: August 2017

Se intenta explicar, mediante datos climáticos modernos, las condiciones que pudieron ser dominantes durante el auge de la Cultura Teotihuacana; asimismo, se trata de encontrar en el clima una razón por la cual desapareció tan floreciente cultura, ya que en varios estudios para conocer las circunstancias del debilitamiento y caída de Teotihuacan, algunos autores aceptan que las causas pudieron haber sido tanto fenómenos adversos del medio, como sociales. Sin tratar de restar importancia a otros factores, se analiza sólo el aspecto climático, principalmente desde el punto de vista de analogías en la precipitación, correlacionando la del área en estudio con la de otras regiones de Europa y África gobernadas por la celda de alta presión Bermuda–Azores. Además, con base en estas correlaciones y hechos históricos reportados en el Viejo Continente, se deducen las fluctuaciones climáticas en el área teotihuacana. La conclusión que se obtiene es que, el clima durante el auge de la Cultura Teotihuacana era tan húmedo como puede ser durante los años más lluviosos en el presente; también se supone que la decadencia y desaparición de dicha cultura se debió, en parte, a la intensa sequía que pudo empezar entre los 700 o 750 años d.C, como sugieren las relaciones entre los datos climáticos y la evidencia histórica en Europa y norte de África.

Destrucción de tierras en el flanco oriental del Nevado de Toluca, el caso de la cuenca del arroyo El Zaguán
Authors: Palacio-Prieto José Luis
Published: August 2017

Las modificaciones en el uso del suelo y la presencia de una capa de grosor variable compuesta de lapilli punítico son dos de los factores más importantes que han tenido como consecuencia la degradación acelerada de tierras en el flanco oriental del volcán Nevado de Toluca, Edo.de México. El estudio geomorfológico detallado de una cuenca ubicada en dicho volcán permitió reconocer sectores inestables desde el punto de vista de producción de sedimentos, los cuales requieren de acción prioritaria para evitar azolvamientos en la desembocadura y consecuentes daños a vías de comunicación, poblados y obras de ingeniería hidráulica. Dentro de las zonas inestables destacan los barrancos de primer orden en gestación y las curvaturas externas en los meandros y sinuosidades desarrollados sobre lahares y tefras pumíticos.

Authors: Patil Bharati , Hegde Sushmini , Yadav Karthik D
Published: August 2017

Myoepithelial carcinoma is a rare tumor of salivary glands, the most frequent site being the parotid gland. Myoepithelial carcinoma of the maxillary sinus has only been reported very few times. As the lesion is very rare in the maxillary sinus and due to the lack of specific guidelines for its treatment, its prognosis remains to be poor. We report a rare case of myoepithelial carcinoma in the maxillary sinus and discuss its diagnostic and therapeutic aspects.

Authors: Sherbon Michael
Published: August 2017

From the exponential function of Euler’s equation to the geometry of a fundamental form, a calculation of the fine-structure constant and its relationship to the proton-electron mass ratio is given. Equations are found for the fundamental constants of the four forces of nature: electromagnetism, the weak force, the strong force and the force of gravitation. Symmetry principles are then associated with traditional physical measures.
Adsorption of volatile polonium species on metals in various gas atmospheres: Part III – Adsorption of volatile polonium on stainless steel 316L
Authors: Maugeri Emilio Andrea , Neuhausen Jörg , Prieto Borja Gonzalez , Aerts Alexander , Mendonça Tania Melo , Stora Thierry , Eichler Robert
Published: August 2017

This article summarizes the results obtained studying the interaction between polonium and stainless steel 316L in different atmospheres by the thermochromatography method. This issue is particularly important in terms of licensing of the MYRRHA prototype ADS reactor, where highly radiotoxic α-emitting polonium isotopes are produced in lead-bismuth eutectic used as both spallation target material and coolant, while stainless steel 316L is going to be the main structural material. The polonium adsorption enthalpy on stainless steel 316L in inert atmosphere was measured as −147±6 kJ mol−1. The findings obtained using reducing atmospheres show that the affinity of polonium for stainless steel 316L increases with the metallic character of the stainless steel surface. The presence of moisture in inert and reducing atmosphere does not significantly influence the polonium adsorption. Oxidizing atmospheres induce the formation of polonium dioxide which has a stronger interaction with the stainless steel 316L, with an adsorption enthalpy of −225±6 kJ mol−1. A prolonged exposure of the stainless steel to strong oxidants, such as pure oxygen, reduces the metallic character of the stainless steel surface and, consequently, its affinity to the polonium oxide. Furthermore, it was found that in all experiments at least 5 ppm of the total polonium present in the starting material were not retained on the stainless steel 316L surface at all.

Nonlinear evidence on the existence of jobless recoveries
Authors: Bradley Michael D. , Jansen Dennis W.
Published: August 2017

The sluggish growth in employment following the Great Recession has spurred research into investigating its cause. Economists are split as to whether it reflects the advent of “jobless recoveries” or just reflects “slow recoveries” in which both output and employment are slow to recover. We estimate a version of Friedman’s plucking model to investigate this issue. We find evidence suggesting that employment does have its own dynamic response after a recession. Some of the slow growth in employment can be ascribed to the slow output growth, but there is a remaining portion which is consistent with the jobless recovery hypothesis. We then produce evidence relative to four different hypothesis of why jobless recoveries have occurred.
Zu möglichen Verbindungen zwischen römischem Mithras und iranischem Mithra
Authors: Lahe Jaan
Published: August 2017

Seit Endes des 19. Jahrhunderts, als die Erforschung des römischen Mithraskultes einsetzte, hat die Frage nach etwaigen Verbindungen dieses Kultes mit der iranischen Religion eine wichtige Rolle gespielt. Weithin unterscheidet man die Theorien, die über mögliche Ursprünge des Mithraismus und dessen Verbindung zum Iran entwickelt wurden, in drei Gruppen: eine „starke iranische These“, die den römischen Mithraskult als eine „iranische Religion” im Römerreich versteht; eine „schwache iranische These”, die besagt, dass die Kernelemente des Mithraskultes genuin iranisch sind, allerdings durch Veränderungen im Westen stark modifiziert wurden; eine „radikale Position“, die etwaige Verbindungen des Kults mit dem Iran verneint oder für nebensächlich hält. Ich bin der Meinung, dass die „starke iranische These“ veraltet ist und dass sich somit jegliche Diskussion hierüber schlichtweg erübrigt hat. Der römische Mitraskult und der Kult um Mithra in der iranischen Religion waren de facto zwei unterschiedliche Kulte. Nichtsdestotrotz gibt es zwischen dem römischen Mithras und dem iranischen Mithra vielfältige Verbindungen. Im vorliegenden Aufsatz setze ich mich kritisch mit einigen Anhaltspunkten, von denen man die letztlich ungebrochene Kontinuität zwischen der Mithra-Verehrung und dem kaiserzeitlichen Mithraismus abzuleiten versucht, auseinander und befrage sie jeweils auf ihre Plausibilität hin, eine solche fundiert herzustellen.
Maximum Distance and High-Speed Distance Demands by Position in NCAA Division I Collegiate Football Games

Published: August 2017

Sanders, GJ, Roll, B, and Peacock, CA. Maximum distance and high-speed distance demands by position in NCAA division I collegiate football games. J Strength Cond Res 31(10): 2728–2733, 2017—The purpose of the study was to quantify the average and maximum distances traveled by National Collegiate Athletic Association division I football athletes during competitive games. Using global positioning system devices (Catapult Sports), total and low-, moderate-, and high-speed distances were quantified by each position. Understanding maximal workloads can enhance conditioning practice periodization protocols. A total of 40 football athletes were included in the analysis. For the data to be included, athletes were required to participate in ≥75% of the offensive or defensive snaps for any given game. There was a total of 286 data downloads from 13 different games for 8 different football positions. Data were calculated and compared by offensive and defensive position to establish the mean, SD, and maximum distances (in meters) traveled during competitive games. A total maximum distance range (Max Range) was established to account for athletes who accumulated in-game total distances greater than the M + 1SD for each position. A percent was also calculated to highlight how often athletes accumulated distance workloads in the Max Range. One-way analysis of variance revealed there was a main effect of football position for all distance variables (p ≤ 0.001). Regardless of position, 12.0–16.7% of the time athletes accumulated in-game total distances in the Max Range. Conditioning and practice periodization protocols for distance should be position specific or individualized to avoid under or over conditioning. In addition, using a Max Range for distance can help ensure athletes are achieving distance workloads that are similar to the demands of a competitive game.

Schlingermann, BE, Lodge, CA, Gissane, C, and Rankin, PM. Effects of the Gaelic Athletic Association 15 on lower extremity injury incidence and neuromuscular functional outcomes in collegiate Gaelic games. J Strength Cond Res 32(7): 1993–2001, 2018—The purpose of this observational analytical cohort study was to assess the effectiveness of an injury prevention program (IPP)—Gaelic Athletic Association 15 (GAA15)—on the incidence of injury in collegiate Gaelic games. One hundred and thirty-one Gaelic games players (mean age 20.5 years ± SD 3.0) were used for analysis in this study. Participants completed preseason and postseason testing which involved performance of the Y-Balance Test. The GAA15 was used for the intervention group; coaches were instructed to implement the program before every training session and match throughout the collegiate Gaelic Athletic Association (GAA) season. The control group adopted their normal warm-up procedures for the season. The players' injuries were documented on a weekly basis by allied health care professionals working with the teams using an online database system. Results showed significant improvements in composite Y-Balance scores in favor of the intervention group (adjusted mean difference Right: 1.8 % normalized mean reach distance (%NMRD) [p = 0.007]/Left: 2.3 %NMRD [p = 0.001]). Injury rates in the intervention group (2.62 injuries per 1,000 hours) were reduced by 66% (p = 0.001) in comparison with an age-matched control group (7.62 per 1,000 hour). Training injuries, hamstring injuries, noncontact injuries, and severe injuries were also reduced as a result of the implementation of the GAA15 (injury rate ratio: 0.20, 0.59, 0.39, and 0.45, respectively). Implementation of an IPP such as the GAA15 can reduce the risk of injury in Gaelic games and influence players' neuromuscular performance assessed through the Y-Balance Test.
Systematic Identification of Determinants for Single-Strand Annealing-Mediated Deletion Formation inSaccharomyces cerevisiae
Authors: Segura-Wang Maia , Onishi-Seebacher Megumi , Stütz Adrian M , Mardin Balca R , Korbel Jan O
Published: August 2017

To ensure genomic integrity, living organisms have evolved diverse molecular processes for sensing and repairing damaged DNA. If improperly repaired, DNA damage can give rise to different types of mutations, an important class of which are genomic structural variants (SVs). In spite of their importance for phenotypic variation and genome evolution, potential contributors to SV formation in Saccharomyces cerevisiae (budding yeast), a highly tractable model organism, are not fully recognized. Here, we developed and applied a genome-wide assay to identify yeast gene knockout mutants associated with de novo deletion formation, in particular single-strand annealing (SSA)-mediated deletion formation, in a systematic manner. In addition to genes previously linked to genome instability, our approach implicates novel genes involved in chromatin remodeling and meiosis in affecting the rate of SSA-mediated deletion formation in the presence or absence of stress conditions induced by DNA-damaging agents. We closely examined two candidate genes, the chromatin remodeling gene IOC4 and the meiosis-related gene MSH4, which when knocked-out resulted in gene expression alterations affecting genes involved in cell division and chromosome organization, as well as DNA repair and recombination, respectively. Our high-throughput approach facilitates the systematic identification of processes linked to the formation of a major class of genetic variation.
Exploring Potential Germline-Associated Roles of the TRIM-NHL Protein NHL-2 Through RNAi Screening
Authors: Davis Gregory M , Low Wai Y , Anderson Joshua W T , Boag Peter R
Published: August 2017

TRIM-NHL proteins are highly conserved regulators of developmental pathways in vertebrates and invertebrates. The TRIM-NHL family member NHL-2 in Caenorhabditis elegans functions as a miRNA cofactor to regulate developmental timing. Similar regulatory roles have been reported in other model systems, with the mammalian ortholog in mice, TRIM32, contributing to muscle and neuronal cell proliferation via miRNA activity. Given the interest associated with TRIM-NHL family proteins, we aimed to further investigate the role of NHL-2 in C. elegans development by using a synthetic RNAi screening approach. Using the ORFeome library, we knocked down 11,942 genes in wild-type animals and nhl-2 null mutants. In total, we identified 42 genes that produced strong reproductive synthetic phenotypes when knocked down in nhl-2 null mutants, with little or no change when knocked down in wild-type animals. These included genes associated with transcriptional processes, chromosomal integrity, and key cofactors of the germline small 22G RNA pathway.

Published: August 2017

Background: Immunoglobulin G (IgG) is a major immunoglobulin (Ig) in blood that accumulates to a greater extent in the bloodstream of patients impacted by neuroimmunological disorders such as multiple sclerosis (MS). The aim of this study was to determine the effect of IgG obtained from MS patients on the amidolytic activity of coagulation and on anticoagulation factors, and to compare those effects to the effects of IgG from healthy donors.

Methods: Spectrophotometric hydrolysis of specific chromogenic substrate by key haemostasis factors was examined.

Results: Our study shows that unlike healthy individuals, patients suffering from MS express IgG which enhances the amidolytic activity of thrombin and protein C, but inhibits the activity of factor Xa.

Conclusion: Our study shows that IgG and coagulation factors, indeed, interact with each other. IgG may be key mediators of neuroinflammation and, therefore, may serve as a potential target for therapeutic strategies for MS and other neuroimmunological diseases.

Authors: Veerasingam Priya , Grant Cameron C. , Chelimo Carol , Philipson Kathryn , Gilchrist Catherine A. , Berry Sarah , Carr Polly Atatoa , Camargo Carlos A. , Morton Susan
Published: August 2017

OBJECTIVES:

Pregnant women routinely receive information in support of or opposing infant immunization. We aimed to describe immunization information sources of future mothers’ and determine if receiving immunization information is associated with infant immunization timeliness.

METHODS:

We analyzed data from a child cohort born 2009–2010 in New Zealand. Pregnant women (N = 6822) at a median gestation of 39 weeks described sources of information encouraging or discouraging infant immunization. Immunizations received by cohort infants were determined through linkage with the National Immunization Register (n = 6682 of 6853 [98%]). Independent associations of immunization information received with immunization timeliness were described by using adjusted odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS:

Immunization information sources were described by 6182 of 6822 (91%) women. Of these, 2416 (39%) received information encouraging immunization, 846 (14%) received discouraging information, and 565 (9%) received both encouraging and discouraging information. Compared with infants of women who received no immunization information (71% immunized on-time), infants of women who received discouraging information only (57% immunized on time, OR = 0.49, 95% CI 0.38–0.64) or encouraging and discouraging information (61% immunized on time, OR = 0.51, 95% CI 0.42–0.63) were at decreased odds of receiving all immunizations on time. Receipt of encouraging information only was not associated with infant immunization timeliness (73% immunized on time, OR = 1.00, 95% CI 0.87–1.15).

CONCLUSIONS:

Receipt, during pregnancy, of information against immunization was associated with delayed infant immunization regardless of receipt of information supporting immunization. In contrast, receipt of encouraging information is not associated with infant immunization timeliness.
Physician-Nurse Interactions in Critical Care
Authors: Khowaja-Punjwani Sumaira , Smardo Charlotte , Hendricks Monica Rita , Lantos John D.
Published: August 2017

Nearly 20% of nurses leave their first job within a year of being hired. Many do so because they perceive the work environment to be unhealthy or nonsupportive. Nurse turnover is costly. When new nurses leave within 3 years of being hired, it costs the hospital $64 000, over and above salaries, to replace them. One of the hallmarks of an unhealthy work environment is poor communication between doctors and nurses. We present a case in which a nurse advocates for a young mother by questioning the doctor. She is reprimanded for doing so. We then asked 3 nurses to discuss the implications of such interactions for nurse satisfaction, patient safety, and a healthy work environment.

Pulmonary function in young females of Kolkata, India – Revisited
Authors: Bandyopadhyay A , Dalui R , Pal S , Bhattacharjee I , Goswami B , Roy AS
Published: August 2017

Rapid economic and industrial growths imposed significant impact on human health including the pulmonary health. Questions were raised regarding the validity of the existing prediction norms of pulmonary function tests (PFTs) in a particular population. The present study was conducted to investigate the applicability of the existing norms for PFTs in young healthy non-smoking female university students of Kolkata, India. Significant difference was noted in vital capacity (VC), forced vital capacity (FVC), and forced expiratory volume in 1 s (FEV1) when the present data were compared with the earlier study in similar population. Correlation statistic revealed significant relationship of age and body height with all the PFT parameters. Body mass had significant correlation with VC, FVC, FEV1 as a percentage of FVC (FEV1%), and peak expiratory flow rate (PEFR). Regression equations have been computed for predicting PFTs from age and body height. There has been a change of PFTs in the studied population for the last couple of decades due to increased environmental pollution in the course of economical and industrial developments. Regression equations computed in this study are not only recommended to predict PFT parameters in the studied population, but they are also considered more reliable owing to their substantially smaller standard error of estimate than those proposed in the previous study.

It is unknown whether age-related site-specific muscle loss is associated with areal bone mineral density (aBMD) in older adults. To examine the relationships between aBMD and whole-body muscle thickness distribution, 97 healthy adults (46 women and 51 men) aged 50–78 years volunteered. Total and appendicular lean soft tissue mass, aBMD of the lumbar spine (LS-aBMD) and femoral neck (FN-aBMD) were determined using dual-energy X-ray absorptiometry. Muscle thickness (MT) was measured by ultrasound at nine sites of the body (forearm, upper arm, trunk, upper leg, and lower leg). Relationships of each co-variate with aBMD were tested partialling out the effect of age. aBMD was not correlated with either MT of the trunk or anterior lower leg in either sex. In men, significant and relatively strong correlations were observed between anterior and posterior upper arms, posterior lower leg, and anterior upper leg MT and LS-aBMD or FN-aBMD. In women, significant correlations were observed between anterior and posterior upper legs, posterior lower leg, and anterior upper arm MT and FN-aBMD. LS-aBMD was only correlated with forearm and posterior upper leg MT in women. In conclusion, the site-specific association of MT and aBMD differs between sexes and may be associated with the participants’ daily physical activity profile.

This study investigated the effects of acute exercise and menstrual phase on adiponectin and osteocalcin concentrations, and the possible role of these biomarkers in exercise-induced substrate oxidation in rowers. Thirteen female rowers (19.3 ± 2.3 years; height: 172.7 ± 3.9 cm; body mass: 66.5 ± 7.9 kg) performed 1-h rowing ergometer exercise at 70% of maximal oxygen consumption (VO2max) during follicular phase and luteal phase of the menstrual cycle. Oxygen consumption (VO2), total energy expenditure (EE), carbohydrate EE, and lipid EE were assessed during the exercise. Venous blood samples were collected before and after ergometer exercise. No differences (p > 0.05) were observed in substrate oxidation values during exercise across menstrual cycle. Exercise resulted in an acute rise in osteocalcin and no changes in adiponectin at both menstrual cycle phases. Adiponectin and osteocalcin were not related across phase or time (r < 0.211; p > 0.05). Post-exercise adiponectin was related (p < 0.05) to mean VO2 (r = 0.459) and total EE rate (r = 0.598), while post-exercise osteocalcin was correlated (p < 0.05) with mean total (r = 0.411) and lipid (r = 0.557) EE rates. In conclusion, menstrual cycle phase had no effect on substrate oxidation, and adiponectin and osteocalcin responses to acute exercise. It appears that adiponectin and osteocalcin may serve as signals for metabolic reaction to the energy cost of the acute exercise in female rowers.

Sobre mestiçagem étnica e expressão da arte
Authors: Barazal Neusa Romero
Published: August 2017

Considerando que a história da humanidade é a história dos movimentos migratórios e suas conseqüentes miscigenações, esta reflexão pretende estabelecer uma aproximação entre a mestiçagem étnica, a arte e a religião. Devido à universalidade da arte e da religião como elementos culturais presentes em todas as sociedades, a mestiçagem aqui será entendida como processo de encontro entre as particularidades culturais que resultam em novas formas misturadas de expressar a arte e a religião mestiças na América Latina.

RESUMO Objetivo: desvelar a percepção do ser humano internado em unidade psiquiátrica sobre o viver com doença mental. Método: trata-se de estudo de abordagem fenomenológica, cujos dados foram obtidos por meio de entrevistas com dez adultos internados em uma unidade psiquiátrica de um hospital de ensino do sul do Brasil, no período de janeiro a março de 2014. Utilizaram-se os passos da fenomenologia-hermenêutica de Paul Ricoeur e, para compreensão e interpretação das informações, o referencial teórico-filosófico de Maurice Merleau-Ponty. Resultados: revelaram três temas: o mundo do ser humano que vivencia a doença mental; percepção da doença mental para o ser humano que vivencia a internação psiquiátrica; e o ser na relação de ambiguidade: o movimento de liberdade. Conclusão: a equipe de saúde, em especial o enfermeiro, necessita incorporar a visão crítica reflexiva da prática assistencial, as bases científicas e a legislação vigente na área da saúde, em especial a saúde mental, as quais visam à autonomia de escolha centrada no ser humano que vivencia a doença mental. Também promover uma rede quente de cuidado singularizado que preze pelo acolhimento e instigue o autocuidado do ser humano por meio da educação em saúde na perspectiva de ações de integralidade. Logo, é fundamental a promoção de saúde, autonomia e liberdade pela escuta do ser humano que vivencia o fenômeno da doença mental, em seus desejos de vida e perspectivas clínicas.
