Se ha reconocido que la presencia de bacterias patógenas en alimentos de origen bovino constituye un riesgo para la salud de las personas, debido a que estos microorganismos son capaces de generar problemas gastrointestinales, y son estas patologías una de las primeras causas de consulta médica y de muerte en México y en el mundo. El presente estudio buscó investigar la presencia de Salmonella sp. y Escherichia coli O157:H7 en 20 muestras de carne molida de res, adquiridas de manera aleatoria en supermercados de la ciudad de Puebla, Puebla, México. Las metodologías utilizadas fueron los procedimientos descritos en la Normas Oficiales Mexicanas: bacterias mesofílicas aerobias (NOM-092-SSA1-1994) y Salmonella sp. (NOM-114-SSA1-1994), que incluyeron las etapas de pre-enriquecimiento, enriquecimiento selectivo, inoculación en medios selectivos y diferenciales e identificación bioquímica y serológica. Aunque no se identificaron cepas de Salmonella sp. ni de E. coli O157:H7, se recomienda continuar con la búsqueda exhaustiva de estas bacterias o de otros agentes patógenos, no sólo en la carne molida de res, sino en otros productos derivados del ganado bovino, con la implementación de técnicas moleculares.

Alcanzar la salud integral, es el principal reto del ser humano para mantener una óptima calidad de vida. Lograr la salud integral requiere del desarrollo coherente del individuo, y para ello deberá prestar atención a todos los aspectos de su vida: físicos (cuerpo), mentales, emocionales (alma) y espirituales. El desarrollo humano coherente en todas estas áreas, contribuye a crear una sociedad más sana. Numerosos estudios han encontrado que las personas sometidas a cambios familiares, sociales y culturales caracterizadas por rupturas emocionales y desorganización social o inestabilidad, están en mayor riesgo de contraer diferentes tipos de enfermedades emocionales y mentales que repercuten en la salud corporal. Para alcanzar la salud integral, se requiere un desarrollo ordenado y coherente a través de las diferentes etapas que integran la vida del individuo y atendiendo sus diferentes áreas de desarrollo. También se requiere el apoyo del núcleo familiar y una correcta alimentación para cada uno de los elementos que integran el ser. En este artículo se realizó una revisión sobre los avances científicos relacionados con la coherencia en el desarrollo integral y la salud.
Naturally fragmented and isolated distribution in subtropical grassland patches affects genetic diversity and structure at different spatial scales: The case of Tibouchina hatschbachii, an endemic shrub from Brazil

Published: November 2017

PREMISE OF THE STUDY:The genetic structure of organisms results from the interactions between life history traits and the ecological and demographic characteristics of the landscape that shape the intra‐ and interpopulation genetic variation in space and time. In this study, we used a species restricted to islands of grassland vegetation in southern Brazil to investigate the effects of its naturally fragmented distribution on diversity and genetic structure patterns.METHODS:Diversity and intra‐ and interpopulational genetic structure were analyzed using polymorphisms of eight nuclear microsatellite markers in 205 individuals of T. hatschbachii and Bayesian and multivariate methods.KEY RESULTS:At the intrapopulation level, populations presented low genetic diversity and strong spatial genetic structure, indicating a greater spatial autocorrelation until ∼50–500 m. At the interpopulation level, genetic variation partitioned into two geographically structured genetic clusters. Gene flow through pollen was more efficient than gene flow by seeds.CONCLUSIONS:Genetic structure was influenced locally by seed and pollen dispersal dynamics and regionally by fragmentation of the grassland landscape. This study highlights the importance of geological barriers, and potentially a role for genetic drift, in influencing diversification of species in subtropical grasslands of southern Brazil.

Published: November 2017

Background Intraperitoneal (IP) administration of ceftazidime is recommended for the treatment of peritoneal dialysis-associated peritonitis (PDAP) from Pseudomonas. Patients with PDAP may also need IP heparin to overcome problems with drainage of turbid peritoneal dialysis (PD) fluids and blockage of catheters with fibrin. Physico-chemical stability of ceftazidime and heparin, and biological stability of heparin in many types of PD solutions is unknown. Therefore, we investigated the stability of ceftazidime and heparin in 4 types of PD solutions. Methods A total of 12 PD bags (3 for each type of solution) containing ceftazidime and heparin were prepared and stored at 4°C for 120 hours, and then at 25°C for 6 hours, and finally at 37°C for 12 hours. An aliquot was withdrawn after predefined time points and analyzed for the concentration of ceftazidime and heparin using high-performance liquid-chromatography (HPLC). Samples were assessed for pH, color changes, particle content, and anticoagulant activity of heparin. Results Ceftazidime and heparin retained more than 91% of their initial concentration when stored at 4°C for 120 hours followed by storage at 25°C for 6 hours and then at 37°C for 12 hours. Heparin retained more than 95% of its initial activity throughout the study period. Particle formation was not detected at any time under the storage conditions. The pH and color remained essentially unchanged throughout the study. Conclusions Ceftazidime-heparin admixture retains its stability over long periods of storage at different temperatures, allowing its potential use for PDAP treatment in outpatient and remote settings.
A Jansky VLA Survey of Magnetic Cataclysmic Variable Stars. I. The Data
Authors: Barrett Paul E. , Dieck Christopher , Beasley Anthony J. , Singh Kulinder P. , Mason Paul A. 
Published: November 2017

Abstract
The Jansky Very Large Array was used to observe 121 magnetic cataclysmic variables (MCVs). We report radio detections of 18 stars. Thirteen are new radio sources, increasing the number of MCVs that are radio sources by more than twofold, from 8 to 21. Most detections are at 8.7 GHz (X-band) with a lesser number at 5.4 and 21.1 GHz (C- and K-bands). With the exception of AE Aqr, whose flux density is typically >5 mJy, the flux densities are in the range of 24–780 μJy. Thirteen of the detections show highly circularly polarized emission, which is characteristic of electron-cyclotron maser emission. The data suggest that MCVs could possibly be divided into two classes of radio emitters: those dominated by weakly polarized gyrosynchrotron emission and those by highly polarized electron-cyclotron maser emission.

Abstract
After the early observations of the disrupted asteroid P/2016 G1 with the 10.4 m Gran Telescopio Canarias (GTC) and modeling of the dust ejecta, we have performed a follow-up observational campaign of this object using the Hubble Space Telescope (HST) during two epochs (2016 June 28 and July 11). The analysis of these HST images with the same model inputs obtained from the GTC images revealed a good consistency with the predicted evolution from the GTC images, so that the model is applicable to the entire observational period from 2016 late April to early July. This result confirms that the resulting dust ejecta was caused by a relatively short-duration event with onset about 350 days before perihelion and spanning about 30 days (HWHM). For a size distribution of particles with a geometric albedo of 0.15, having radii limits of 1 μm and 1 cm, and following a power-law with index −3.0, the total dust mass ejected is ∼2 × 107 kg. As was the case with the GTC observations, no condensations in the images that could be attributed to a nucleus or fragments released after the disruption event were found. However, the higher limiting magnitude reachable with the HST images in comparison to those from GTC allowed us to impose a more stringent upper limit to the observed fragments of ∼30 m.

Abstract
HC3N is a ubiquitous molecule in interstellar environments, from external galaxies to Galactic interstellar clouds, star-forming regions, and planetary atmospheres. Observations of its rotational and vibrational transitions provide important information on the physical and chemical structures of the above environments. We present the most complete global analysis of the spectroscopic data of HC3N. We recorded the high-resolution infrared spectrum from 450 to 1350 cm−1, a region dominated by the intense

and

fundamental bands, located at 660 and 500 cm−1, respectively, and their associated hot bands. Pure rotational transitions in the ground and vibrationally excited states were recorded in the millimeter and submillimeter regions in order to extend the frequency range so far considered in previous investigations. All of the transitions from the literature and from this work involving energy levels lower than 1000 cm−1 were fitted together to an effective Hamiltonian. Because of the presence of various anharmonic resonances, the Hamiltonian includes a number of interaction constants, in addition to the conventional rotational and vibrational l-type resonance terms. The data set contains about 3400 ro-vibrational lines of 13 bands and some 1500 pure rotational lines belonging to 12 vibrational states. More than 120 spectroscopic constants were determined directly from the fit, without any assumption deduced from theoretical calculations or comparisons with similar molecules. An extensive list of highly accurate rest frequencies was produced to assist astronomical searches and data interpretation. These improved data enabled a refined analysis of the ALMA observations toward Sgr B2(N2).
Data-driven Modeling of the Solar Corona by a New Three-dimensional Path-conservative Osher–Solomon MHD Model

Published: November 2017

Abstract
A second-order path-conservative scheme with a Godunov-type finite-volume method has been implemented to advance the equations of single-fluid solar wind plasma magnetohydrodynamics (MHD) in time. This code operates on the six-component composite grid system in three-dimensional spherical coordinates with hexahedral cells of quadrilateral frustum type. The generalized Osher–Solomon Riemann solver is employed based on a numerical integration of the path-dependent dissipation matrix. For simplicity, the straight line segment path is used, and the path integral is evaluated in a fully numerical way by a high-order numerical Gauss–Legendre quadrature. Besides its very close similarity to Godunov type, the resulting scheme retains the attractive features of the original solver: it is nonlinear, free of entropy-fix, differentiable, and complete, in that each characteristic field results in a different numerical viscosity, due to the full use of the MHD eigenstructure. By using a minmod limiter for spatial oscillation control, the path-conservative scheme is realized for the generalized Lagrange multiplier and the extended generalized Lagrange multiplier formulation of solar wind MHD systems. This new model that is second order in space and time is written in the FORTRAN language with Message Passing Interface parallelization and validated in modeling the time-dependent large-scale structure of the solar corona, driven continuously by Global Oscillation Network Group data. To demonstrate the suitability of our code for the simulation of solar wind, we present selected results from 2009 October 9 to 2009 December 29 show its capability of producing a structured solar corona in agreement with solar coronal observations.
Prenatal Diagnosis of Cross-fused Renal Ectopia: Still a Dilemma
Authors: Singhania Pooja 
Published: November 2017

ABSTRACT
Cross-fused renal ectopia (CRE) is a rare congenital anomaly where during development of the fetus, one kidney migrates to the opposite side and fuses with the kidney of that side. Crossfused ectopic kidney with contralateral pelvic kidney is a rare finding. Proper knowledge of morphological variations of kidneys is essential to avoid postnatal renal dysfunction and morbidity.

Comparative Study of Potential Diagnostic Biomarkers in Myocardial Infarction with Survival and Myocardial Infarction without Survival
Authors: Patil Sangita M , Bankar Mangesh , Padalkar Ramchandra , Phatak Abhijit 
Published: November 2017

ABSTRACT

Introduction
Because of the varied presentation and associated high mortality, the identification of patients with acute myocardial infarction (MI) is very critical for patient management and has a bearing on the prognosis. The goal of present study was to correlate the diagnostic value of cardiac biomarkers in MI with survival and MI without survival.

Materials and methods
Diagnostic case—control study was conducted on 110 MI patients presenting to the Emergency Department within 12 hours of acute chest pain, and 120 healthy age- and sex-matched volunteers formed the control group. Serum ischemia-modified albumin (IMA), troponin I (TnI), creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH), and aspartate transaminase (AST) were measured. Statistical software SYSTAT version 12 was used to analyze the data. The results were expressed in mean ± standard deviation. Comparisons of study groups and study groups with control groups were done by applying Z test. Correlation was tested by Student's t-test at 5% (p = 0.05) and 1% (p = 0.01) level of significance.

Results
Mean levels of serum IMA, TnI, CK-MB, LDH, and AST levels were significantly higher (p < 0.01) in patients with MI as compared with healthy controls. Serum levels of cardiac biomarkers were significantly elevated (p < 0.01) in MI patients without survival as compared with MI with survival.

Conclusion
The serum levels of biomarkers were increased in MI without survival as compared with MI with survival. These study data prove that these changes might be helpful to obtain a comprehensive view of the infarct size and severity of vascular stenotic lesions.

Study of Parathyroid Hormone as an Independent Risk Marker of Heart Failure
Authors: Iyyapu Krishna M , Yerram Sreekanth , Sai Baba Kompella SS 
Published: November 2017

ABSTRACTIntroductionHeart failure (HF) is a clinical syndrome characterized by cardiac pump failure with signs and symptoms arising from salt and water retention. Heart failure is associated with considerable mortality and morbidity. Identification of modifiable risk factors may reduce incidence of HF and its complications. The aim of our study is to assess parathyroid hormone (PTH) as a risk marker for HF and its association with severity of HF.Materials and methodsIn this cross-sectional study, 120 subjects with HF were recruited and they were compared with 60 age- and sex-matched controls. Along with the routine parameters, N-terminal pro B-type natriuretic peptide (NT-proBNP), intact PTH, and vitamin D were estimated. The study group was divided into quartiles depending on PTH value.ResultsThe median PTH (81.5 pg/mL) and NT-proBNP (3753 pg/mL) in HF patients are found to be significantly higher (p < 0.0001) when compared with control subjects. The median vitamin D concentration (18 ng/mL) though low in cases is not statistically significant when compared with controls. Demographic, clinical, and laboratory characteristics are compared across the quartiles of PTH. Highest number of New York Heart Association (NYHA) class IV HF cases are found in highest quartiles of PTH. Logistic regression analysis demonstrated that high concentration of PTH [odds ratio of 1.1113; 95% confidence interval (CI) 1.07—1.14; p < 0.0001] and low levels of vitamin D (odds ratio of 1.053; 95% CI 1.0079—1.1009) are significantly associated with HF.ConclusionThis study has demonstrated that higher concentration of PTH is associated with severe form of HF. Vitamin D deficiency is also seen in the study group.How to cite this articleKhan SA, Iyyapu KM, Sai Baba KSS, Yerram S. Study of Parathyroid Hormone as an Independent Risk Marker of Heart Failure.

System for δ13C–CO2 and xCO2 analysis of discrete gas samples by cavity ring-down spectroscopy
Authors: Dickinson Dane , Bodé Samuel , Boeckx Pascal 
Published: November 2017

Abstract. A method was devised for analysing small discrete gas samples (50 mL syringe) by cavity ring-down spectroscopy (CRDS). Measurements were accomplished by inletting 50 mL syringed samples into an isotopic-CO2 CRDS analyser (Picarro G2131-i) between baseline readings of a reference air standard, which produced sharp peaks in the CRDS data feed. A custom software script was developed to manage the measurement process and aggregate sample data in real time. The method was successfully tested with CO2 mole fractions (xCO2) ranging from  <  0.1 to  >  20 000 ppm and δ13C–CO2 values from −100 up to +30 000 ‰ in comparison to VPDB (Vienna Pee Dee Belemnite). Throughput was typically 10 samples h−1, with 13 h−1 possible under ideal conditions. The measurement failure rate in routine use was ca. 1 %. Calibration to correct for memory effects was performed with gravimetric gas standards ranging from 0.05 to 2109 ppm xCO2 and δ13C–CO2 levels varying from −27.3 to +21 740 ‰. Repeatability tests demonstrated that method precision for 50 mL samples was ca. 0.05 % in xCO2 and 0.15 ‰ in δ13C–CO2 for CO2 compositions from 300 to 2000 ppm with natural abundance 13C. Long-term method consistency was tested over a 9-month period, with results showing no systematic measurement drift over time. Standardised analysis of discrete gas samples expands the scope of application for isotopic-CO2 CRDS and enhances its potential for replacing conventional isotope ratio measurement techniques. Our method involves minimal set-up costs and can be readily implemented in Picarro G2131-i and G2201-i analysers or tailored for use with other CRDS instruments and trace gases.
Nietzsche and the Art of Cruelty
Authors: Parmer W. Jared 
Published: November 2017

Abstract
This article explains Nietzsche's high regard for cruelty. After offering a conceptual analysis of cruel acts, it argues that they are an apt means of expressing one's power, drawing from work on Nietzsche's psychological views and doctrine of the will to power to do so. In addition to the benefit that perpetrators of cruelty can enjoy in virtue of expressing their power, victims, by enduring cruelty, can cultivate qualities essential to overcoming the terrible truths of existence. Finally, central to most of Nietzsche's remarks on the matter, self-directed cruelty has deep connections with the process of sublimation, which makes possible greater and more varied modes of life. In light of this picture, the liberal equation of suffering with harm becomes questionable, as does the insistence that cruelty deprives an individual of her agency. Self-cruelty, in particular, comes to look like one of the best expressions of agency.
Creating Artistry: Pathways to Teacher Growth in a Professional Development Short Course
Authors: Shaw Julia T. 
Published: November 2017

Abstract
This collective case study explored the efficacy of a short-course professional development format for fostering music teachers’ professional growth. Data generated with 2 professional development providers and 7 participants in a 7-day workshop for teacher-conductors offered insights into how the short course prompted teachers’ reflection and catalyzed changes in their practice. Themes revolved around participants’ evolving visions of the teacher-conductor role, personal risks associated with teacher reflection, and enabling conditions supporting teachers’ professional growth. Profiles of individual teacher-learners’ varied growth trajectories during the short course illustrated the complex, nonlinear, and idiosyncratic nature of teachers’ professional growth. Implications for professional development meeting the needs of experienced music educators are discussed based on these findings.
Gryzelda Wiśniowiecka: Ordynat and Kingmaker, A Woman in the Political Life of the Polish-Lithuanian Commonwealth
Authors: Doucette Siobhan 
Published: November 2017

Abstract
This article focuses on Gryzelda Wiśniowiecka (1623–1672) and her previously unexplored influence on the political life of the Polish-Lithuanian Commonwealth; notably the 1669 royal election of Michał Korybut Wiśniowiecki. Wiśniowiecka was the first female citizen of the Polish-Lithuanian Commonwealth to administer an Ordynacja in her own right and the first to see her son elected king. This article argues that Wiśniowiecka achieved these distinctions by capitalizing on the political divisions in the country between the “magnates,” who often associated with foreign rulers, and the szlachta majority, who feared that foreign influences, centralization, and even absolutism were replacing the republicanism and egalitarianism which they associated with the Commonwealth. By juxtaposing Wiśniowiecka’s political activism with that of her sister-in-law, Maria Kazimiera, different ways in which women could exert power in the Commonwealth emerge.
