Bee honey color variation throughout the year in Hejotitán, Jalisco, México.

Bee honey is a highly valued food whose international marketing is controlled by quality standards that are based on its physicochemical properties. One of them is color, which does not reflect a high or low quality, but rather the preferences of certain consumer markets. Color in honey is mostly determined by its floral sources that constantly change throughout the year. This study was intended to record color variations of the honey collected by Apis mellifera. For this purpose, honey was sampled from three selected hives, in an apiary in the town of Huejotitan, state of Jalisco, in western Mexico, on a monthly basis for a year. Color was measured according to the Pfund scale. Humidity was also measured since fermentation due to excessive moisture could spoil the samples. Two additional samples were collected, as well, from the bulk of honey at the time of the harvests, directly from the extractor: one from the spring harvest in May 2012, and the other from the fall harvest in December 2012. A total of 23 samples were obtained from December 2011 to December 2012. Color ranged from 0 mm Pfund (water white) to 85 mm Pfund (light amber) and humidity from 17% to 24%. It was discovered that the samples collected during the peak of the nectar flow, October - November, were contrastingly whiter than the rest. Although requiring more work, since consumers prefer clearer honeys, it is concluded that honey harvested at intervals during the high flow in the hives, with careful consideration of the moisture and making sure to keep honeys from different hives, apiaries and producers separate, a wider variety of honeys would be obtained, with different shades of color and different properties, better targeting the more specialized and demanding markets of today

Risk Factors and Predictive Score for Bacteremic Biliary Tract Infections Due to Enterococcus faecalis and Enterococcus faecium: a Multicenter Cohort Study from the PROBAC Project

Biliary-tract bloodstream infections (BT-BSI) caused by Enterococcus faecalis and E. faecium are associated with inappropriate empirical treatment and worse outcomes compared to other etiologies. The objective of this study was to investigate the risk factors for enterococcal BT-BSI. Patients with BT-BSI from the PROBAC cohort, including consecutive patients with BSI in 26 Spanish hospitals between October 2016 and March 2017, were selected; episodes caused by E. faecalis or E. faecium and other causes were compared. Independent predictors for enterococci were identified by logistic regression, and a predictive score was developed. Eight hundred fifty episodes of BT-BSI were included; 73 (8.5%) were due to target Enterococcus spp. (48 [66%] were E. faecium and 25 [34%] E. faecalis). By multivariate analysis, the variables independently associated with Enterococcus spp. were (OR; 95% confidence interval): cholangiocarcinoma (4.48;1.32 to 15.25), hospital acquisition (3.58;2.11 to 6.07), use of carbapenems in the previous month (3.35;1.45 to 7.78), biliary prosthesis (2.19;1.24 to 3.90), and moderate or severe chronic kidney disease (1.55;1.07 to 2.26). The AUC of the model was 0.74 [95% CI0.67 to 0.80]. A score was developed, with 7, 6, 5, 4, and 2 points for these variables, respectively, with a negative predictive value of 95% for a score # 6. A model, including cholangiocarcinoma, biliary prosthesis, hospital acquisition, previous carbapenems, and chronic kidney disease showed moderate prediction ability for enterococcal BT-BSI. Although the score will need to be validated, this information may be useful for deciding empirical therapy in biliary tract infections when bacteremia is suspected. IMPORTANCE Biliary tract infections are frequent, and a significant cause of morbidity and mortality. Bacteremia is common in these infections, particularly in the elderly and patients with cancer. Inappropriate empirical treatment has been associated with increased risk of mortality in bacteremic cholangitis, and the probability of receiving inactive empirical treatment is higher in episodes caused by enterococci. This is because many of the antimicrobial agents recommended in guidelines for biliary tract infections lack activity against these organisms. To the best of our knowledge, this is the first study analyzing the predictive factors for enterococcal BT-BSI and deriving a predictive score.8 página

Multi-messenger observations of a binary neutron star merger

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta

los Dientes supernumerarios incluidos en torus mandibulares bilaterales: consideraciones genéticas y reporte de un caso: Titulo corto: supernumerarios en torus mandibulares bilaterales

Abstract Introduction: Despite advances in the knowledge of dental morphogenesis, differentiation and formation of maxillary bones, relatively little is known about the etiology and molecular mechanisms underlying the formation of supernumerary teeth (DS) and some theories about the joint presence of bilateral mandibular torus (TM). Case report: The following describes a clinical situation of a female patient with a family history of DS, who was diagnosed clinically and tomographically with DS included in the body of bilateral TM, which manifested pain in the floor of the mouth when chewing, prior to signing an informed consent was surgically submitted to the removal of TM and DS. Results: after the application of a management protocol with two serial surgeries at different times, it was possible to obtain in a favorable way the final resolution of the reason for consultation of the patient with satisfactory evolution without complications. Conclusion: due to the unusualness of the case, surgical treatment is the most radical option, however, the etiology from the genetic context is not clear the coexistence of DS and TM.Introducción: A pesar de los avances en el conocimiento de la morfogénesis dental, diferenciación y formación de los huesos maxilares, se sabe relativamente poco sobre la etiología y los mecanismos moleculares que subyacen a la formación de los dientes supernumerarios (DS) y algunas teorías sobre la presencia conjunta torus mandibulares (TM) bilaterales. Reporte del caso: A continuación se describe un situación clínica de una paciente femenina con antecedentes familiares de DS, la cual fue diagnósticada de manera clínica y tomográfica con DS incluidos en el cuerpo de TM bilaterales, la cual manifestaba dolor en el piso de la boca al masticar, previo a la firma de un consentimiento informado fue sometida quirúrgicamente a la remoción del TM y los DS. Resultados: después de la aplicación de un protocolo de manejo con dos cirugías seriadas en diferentes tiempos se logró obtener de manera favorable la resolución final del motivo de consulta de la paciente con evolución satisfactoria sin complicaciones. Conclusión: por lo inusual del caso, el tratamiento quirúrgico es la opción más radical, sin embargo, la etiología desde el contexto genético no está clara la coexistencia de DS y TM

Late embryonic losses in lactating dairy cows: risk factors and reproductive performance

La pérdida de gestación es reconocida como una de las principales causas de ineficiencia reproductiva en vacas lecheras. El objetivo de este trabajo fue evaluar los factores de riesgo de la muerte embrionaria tardía (MET) detectada por ultrasonografía (US) entre los 28-42 días post inseminación artificial (IA) y su asociación con la eficiencia reproductiva. Se realizó un estudio retrospectivo de casos y controles donde fueron analizados los registros productivos, reproductivos y sanitarios de 13.551 lactancias iniciadas entre el 1 de enero de 2011 y el 31 de diciembre de 2015 de un tambo comercial en Argentina. Se encontró que el riesgo de MET aumentó en vacas multíparas (OR=1,58) y con baja condición corporal (CC, OR=1,82). Además, las vacas que tuvieron MET tuvieron 3 veces menos chance de quedar preñadas y tuvieron un intervalo parto concepción 108 días más largo con respecto a las que no tuvieron MET. En conclusión, los factores de riesgo de MET fueron el número de partos y la CC, y la MET se asoció negativamente con la eficiencia reproductiva.Late embryonic loss (LEL) is recognized as one of the major causes of reproductive failure in dairy cows. The objectives of this study were to evaluate risk factors for (LEL) 28-42 days post-AI and its association with reproductive performance. A retrospective casecontrol study was run using a dataset from a commercial dairy farm from Argentina involving productive, reproductive, and health records of 13551 lactations started between January 1, 2011, and December 31, 2015. The risk for LEL increased in multiparous cows (OR = 1.58) and in low BCS cows (OR = 1.82). Cows with LEL had 3 times lower hazard of pregnancy and 108 d longer inter-calving interval than its herd mates. In conclusion, risk factors for LEL are parity and body condition score, and LEL was negatively associated with reproductive performance.Fil: Quintero Rodriguez, Luis Ernesto.

Diplomado en Servicios Públicos Domiciliarios

In the present work, addresses the contemporary view of the concept of domestic public services in Colombia, reviewing the public policies which make the rights of users effective, free competition, socio-environmental responsibility of companies providing public services, inclusion of the criterion of sustainability that is evidenced in aspects such as renewable energies and inclusion of management indicators of high environmental quality for companies providing the public service and finally the particularities of employment regimen in the context of privatization processes. Certainly, the management model for public utilities is in compliance with the regulatory guidelines redesigned in the 1990s and in turn is articulated with the model of sustainable development adopted in the Constitution, allowing the participation of both private capital and public capital for an optimal provision of the service, that responds to the basic principles of universality, low tariffs, continuity of service and efficiency. All of which gives rise to a series of specific legal relationships between the State and the companies that are governed by the concession contracts and by the state's regulatory authority, between the companies and their users, which is guided by uniform conditions contracts and between the companies and their workers with certain peculiarities in the employment regimen.En el presente trabajo aborda una visión contemporánea del concepto de los servicios públicos domiciliarios en Colombia, abordando las políticas públicas que hacen efectivos los derechos que de los usuarios, la libre competencia, la responsabilidad socio ambiental de las empresas prestadoras de servicios públicos, la inclusión del criterio de sostenibilidad que se evidencia en aspectos como energías renovables e inclusión de indicadores de gestión de alta calidad ambiental para las empresas prestadoras del servicio público y finalmente las particularidades de las relaciones laborales en el contexto de los procesos de privatización. Ciertamente, el modelo de gestión de los servicios públicos domiciliarios guarda observancia de las directrices regulatorias rediseñadas en los años noventa y a su vez se articula con el modelo de desarrollo sostenible adoptado en la Constitución Política, permitiendo la participación tanto de capital privado como por capital público para una óptima prestación del servicio que responda a los principios básicos de universalidad, continuidad en la prestación y eficiencia. Todo lo cual, da origen a una serie de relaciones jurídicas específicas entre el Estado con las empresas que se rige por los contratos de concesión y por la facultad regulatoria del Estado, ente las empresas y sus usuarios que se orienta por los contratos de condiciones uniformes y entre las empresas y sus trabajadores con ciertas particularidades en el régimen laboral
