The National High Magnetic Field Laboratory has brought to field a Series-Connected Hybrid magnet for NMR spectroscopy. As a DC powered magnet it can be operated at fields up to 36.1T. The series connection between a superconducting outsert and a resistive insert dramatically minimizes the high frequency fluctuations of the magnetic field typically observed in purely resistive magnets. Current-density-grading among various resistive coils was used for improved field homogeneity. The 48mm magnet bore and 42mm outer diameter of the probes leaves limited space for conventional shims and consequently a combination of resistive and ferromagnetic shims are used...

La mayoría de las especies del género Dermestes (Coleoptera: Dermestidae) son carroñeras durante la fase larvaria y la fase adulta, con preferencia por la materia orgánica seca. Debido a esto, los derméstidos son indicadores potencialmente útiles en las investigaciones forenses que impliquen restos humanos momificados y/o esqueléticos. Lamentablemente, los datos de referencia sobre el desarrollo de la mayoría de las especies de Dermestes de relevancia forense son escasos. Este estudio analiza el efecto de cinco temperaturas constantes (15, 20, 25, 30 y 35 °C) sobre la supervivencia y la tasa de desarrollo de tres de los derméstidos de mayor relevancia forense: Dermestes frischii Kugelan, Dermestes maculatus De Geer y Dermestes undulatus Brahm...

Los costos de la atención médica pueden alcanzar niveles tales que marginen a algunos pacientes de los beneficios del avance científico y tecnológico. Las razones de estos elevados costos son diversas y en la mayoría de los casos no está en manos de los médicos moderarlos. En este escrito se proponen algunas acciones que los médicos podemos realizar para disminuir los costos de la atención médica. La magnitud del ahorro que se puede alcanzar con estas medidas es modesta, puesto que la mayor parte de los costos no dependen de los médicos, pero se trata de ofrecer nuestra contribución...

Violence has a negative impact on adolescents and affects their quality of life. It causes stress and requires the victim's adaptive capacity, which can cause psychological and biological changes. Hormone cortisol levels have been used as stress biomarker in several studies. This paper aims to perform a systematic literature review of publications on cortisol and violence involving teenagers from 2000 to 2013. Descriptors "cortisol", "violence" and "adolescent" were used in both English and Portuguese in this review, which included bibliographic databases PubMed/Medline, Lilacs, BVS and SciELO...

Seguro que todos compartimos que el gasto sanitario ha crecido progresivamente año tras año en las últimas décadas. Los expertos apuntan, de una forma muy simplista, que el aumento de la demanda sanitaria (aumento de crónicas y degenerativas; envejecimiento de la población) y el incremento de costes de los elementos que comportan la oferta (avances tecnológicos) son las causas que lo provocan. También entendemos que este tipo de presión, lejos de disminuir, en un futuro próximo se prevé que seguirá en crecimiento...

BACKGROUND: Analysis of the stool samples is an essential part of routine diagnostics of the helminthes infections. However, the standard methods such Kato and Kato-Katz utilize only a fraction of the information available. Here we present a method based on the nuclear magnetic resonance spectroscopy (NMR) which could be auxiliary to the standard procedures by evaluating the complex metabolic profiles (or phenotypes) of the samples. METHOD: The samples were collected over the period of June-July 2015, frozen at -20 °C at the site of collection and transferred within four hours for the permanent storage at -80 °C...

PURPOSE: During trigeminal nerve repair, a gap is sometimes encountered that prevents the tension-free apposition of nerve endings. The use of a processed acellular nerve allograft is a novel technique that shows promise in overcoming this problem. The goal of the present study was to support the slowly evolving body of evidence that acellular processed nerve allografts (Avance; Axogen, Alachua, FL) are a viable alternative to autogenous nerve grafting and the use of conduits for reconstructing defects of the trigeminal nerve...

BACKGROUND: We observed that increasing fresh gas flow (FGF) decreased exhaled tidal volume (VT) during pressure control ventilation (PCV). A literature search produced no such description whereby unintended VT changes occur with FGF changes during PCV. METHODS: To model an infant's lungs, 1 lung of a mechanical lung model (Dual Adult TTL 1600; Michigan Instruments, Inc, Grand Rapids, MI) was set at a compliance of 0.0068 L/cm H2O. An Rp50 resistor (27.2 cm H2O/L/s at 15 L/min) simulated normal bronchial resistance...

Processed nerve allografts (PNAs) have been demonstrated to have improved clinical results compared with hollow conduits for reconstruction of digital nerve gaps less than 25 mm; however, the use of PNAs for longer gaps warrants further clinical investigation. Long nerve gaps have been traditionally hard to study because of low incidence. The advent of the RANGER registry, a large, institutional review board-approved, active database for PNA (Avance Nerve Graft; AxoGen, Inc, Alachua, FL) has allowed evaluation of lower incidence subsets...

To improve the in situ monitoring of thin films at the Laboratoire des Matériaux Avancés, a broadband optical monitoring of the coated thin films was developed and installed in the biggest ion-beam sputtering machine in the world. Due to the configuration of the coating machine and the chamber strain under vacuum, a standard calibration procedure is impossible and a double-beam optical system is not suitable. A novel theoretical and practical solution to calibrate the measurements was found and is described in this paper...
