Positive contrast MR-lymphography using inversion recovery with ON-resonant water suppression (IRON).

PURPOSE: To investigate the utility of inversion recovery with ON-resonant water suppression (IRON) to create positive signal in normal lymph nodes after injection of superparamagnetic nanoparticles. MATERIALS AND METHODS: Experiments were conducted on six rabbits, which received a single bolus injection of 80 mumol Fe/kg monocrystalline iron oxide nanoparticle (MION-47). Magnetic resonance imaging (MRI) was performed at baseline, 1 day, and 3 days after MION-47 injection using conventional T(1)- and T(2)*-weighted sequences and IRON. Contrast-to-noise ratios (CNR) were measured in blood and in paraaortic lymph nodes. RESULTS: On T(2)*-weighted images, as expected, signal attenuation was observed in areas of paraaortic lymph nodes after MION-47 injection. However, using IRON the paraaortic lymph nodes exhibited very high contrast enhancement, which remained 3 days after injection. CNR with IRON was 2.2 +/- 0.8 at baseline, increased markedly 1 day after injection (23.5 +/- 5.4, P < 0.01 vs. baseline), and remained high after 3 days (21.8 +/- 5.7, *P < 0.01 vs. baseline). CNR was also high in blood 1 day after injection (42.7 +/- 7.2 vs. 1.8 +/- 0.7 at baseline, P < 0.01) but approached baseline after 3 days (1.9 +/- 1.4, P = NS vs. baseline). CONCLUSION: IRON in conjunction with superparamagnetic nanoparticles can be used to perform 'positive contrast' MR-lymphography, particularly 3 days after injection of the contrast agent, when signal is no longer visible within blood vessels. The proposed method may have potential as an adjunct for nodal staging in cancer screening.

Plan de seguridad y salud para el suministro y montaje del Parque Eólico Rancho Viejo en el T.M. de Medina-Sidonia (Cádiz)

No hace más de 3 años se podía leer en las revistas especializadas que España había pasado a ocupar el tercer puesto en el ranking mundial por potencia eólica instalada. La industria eólica española a su vez ha pasado a ocupar el tercer puesto en la fabricación e instalación de aerogeneradores, con una cuota de mercado del 13%, siendo así un sector con gran capacidad de exportación. Por otra parte, tras diez años de promulgación de la Ley 31/95, de 8 de noviembre, de Prevención de Riesgos Laborales, y después su desarrollo reglamentario, es un hecho incontestable que, pese a todo, y a los ingentes esfuerzos realizados por los distintos actores implicados en la prevención de riesgos laborales (Estado, Comunidades Autónomas, Agentes Sociales, Entidades especializadas, etcetera), existe un sector como el de la construcción que, constituyendo uno de los ejes del crecimiento económico de nuestro país, está sometido a unos riesgos especiales y continúa registrando una siniestralidad laboral muy notoria por sus cifras y gravedad. La legislación de prevención, los manuales sobre las distintas disciplinas preventivas, los libros especializados, los expertos... han abordado ya, con mayor o menor acierto, muchas de las cuestiones generales y específicas que afectan a la seguridad y salud: la evaluación de riesgos, las medidas higiénicas, los equipos de trabajo y equipos de protección individual, la planificación, la formación, los servicios de prevención , los sistemas de gestión de la prevención, las auditorías ... forman parte de los contenidos que se han ido creando en torno a este tema. No obstante, resulta de gran interés la elaboración de un estudio de Seguridad y Salud, en el que partiendo de un desarrollo técnico concreto, pero sobre todo integral, es decir, que comprenda todas las fases para el suministrp e instalación de aerogeneradores para un parque eólico, vayamos desgranando cada uno de los puntos desarrollados en su construcción. Entre las conclusiones más destacadas de este trabajo, se encuentra la definición de las condiciones relativas a la prevención de accidentes y enfermedades laborales durante la ejecución de los trabajos de suministro e instalación de un parque eólico y la gestión de su prevención, las características de las instalaciones preceptivas para higiene y bienestar de los trabajadores, así como directrices básicas mínimas, que deben reflejarse y desarrollarse en el Plan de Seguridad y Salud que las empresas contratistas deberán presentar para su aprobación por el director de obra, antes del comienzo de los trabajos, de forma que sea posible la disminución de accidentes laborales así como evitar las posibles sanciones administrativas y/o penales.

Regenerative cell injection in denervated muscle reduces atrophy and enhances recovery following nerve repair.

INTRODUCTION: Functional muscle recovery after peripheral nerve injury is far from optimal, partly due to atrophy of the muscle arising from prolonged denervation. We hypothesized that injecting regenerative cells into denervated muscle would reduce this atrophy. METHODS: A rat sciatic nerve lesion was performed, and Schwann cells or adipose-derived stem cells, untreated or induced to a "Schwann-cell-like" phenotype (dASC), were injected into the gastrocnemius muscle. Nerves were either repaired immediately or capped to prevent muscle reinnervation. One month later, functionality was measured using a walking track test, and muscle atrophy was assessed by examining muscle weight and histology. RESULTS: Schwann cells and dASC groups showed significantly better scores on functional tests when compared with injections of growth medium alone. Muscle weight and histology were also significantly improved in these groups. CONCLUSION: Cell injections may reduce muscle atrophy and could benefit nerve injury patients.

Iowa Aviation Plan, 2004-2024

The Iowa Department of Transportation (DOT), working closely with the Federal Aviation Administration (FAA), strives to ensure that Iowa’s system of public airports is positioned to meet the needs of businesses, residents, and visitors to our state. Airports must be accessible and positioned to safely meet different levels of aviation activity. In partnership with the FAA and various cities, counties, and airport authorities, the Iowa DOT helps to direct the systematic development of public airports. This report is a summary of a more comprehensive technical report that outlines a strategic plan for improving the performance of airports in Iowa over the next 20 years. More information on the technical report and on individual reports prepared for each of the public airports can be obtained from the Iowa DOT, Office of Aviation website at www.iawings.com. The Iowa Aviation System Plan provides the Iowa DOT with an important tool to monitor the ability of airports to meet customer needs. The plan also provides a means to measure the effects of investment on the performance of the Iowa Aviation System. Over the next 20 years, federal, state, local, and private funding will be needed to ensure that the aviation system meets goals established in this study. It is estimated that at least $821 million will be needed over the next 20 years if airports in Iowa are to respond to objectives set by the system plan. In future years, the plan will enable the Iowa DOT to measure system performance. By tracking key indicators for the airport system, it will be possible for the Iowa DOT and the FAA to formulate strategies for responding to Iowa’s air transportation needs. The Iowa Aviation System Plan provides a guide for the state and its communities to ensure that the vision established for the Iowa Aviation System can be achieved.

Federal agencies will shortly begin distributing funding from the American Recovery and Reinvestment Act of 2009 (Recovery Act). They must do so in accordance with all nondiscrimination and equal opportunity statutes, regulations, and Executive Orders that apply to the distribution of funds under the Recovery Act. Agencies that grant funds also must ensure that their recipients and sub recipients comply with Title VI of the Civil Rights Act of 1964 (prohibiting race, color, and national origin discrimination including language access for limited English proficient persons), Section 504 of the rehabilitation Act of 1973 (prohibiting disability discrimination), Title IX of the Education Amendments of 1972 (prohibiting sex discrimination in education and training programs), the Age Discrimination Act of 1975 (prohibiting age discrimination in the provision of services), and a variety of program-specific statutes with nondiscrimination requirements.

Steady-state equilibrium phase inversion recovery ON-resonant water suppression (IRON) MR angiography in conjunction with superparamagnetic nanoparticles. A robust technique for imaging within a wide range of contrast agent dosages.

PURPOSE: To investigate the ability of inversion recovery ON-resonant water suppression (IRON) in conjunction with P904 (superparamagnetic nanoparticles which consisting of a maghemite core coated with a low-molecular-weight amino-alcohol derivative of glucose) to perform steady-state equilibrium phase MR angiography (MRA) over a wide dose range. MATERIALS AND METHODS: Experiments were approved by the institutional animal care committee. Rabbits (n = 12) were imaged at baseline and serially after the administration of 10 incremental dosages of 0.57-5.7 mgFe/Kg P904. Conventional T1-weighted and IRON MRA were obtained on a clinical 1.5 Tesla (T) scanner to image the thoracic and abdominal aorta, and peripheral vessels. Contrast-to-noise ratios (CNR) and vessel sharpness were quantified. RESULTS: Using IRON MRA, CNR and vessel sharpness progressively increased with incremental dosages of the contrast agent P904, exhibiting constantly higher contrast values than T1 -weighted MRA over a very wide range of contrast agent doses (CNR of 18.8 ± 5.6 for IRON versus 11.1 ± 2.8 for T1 -weighted MRA at 1.71 mgFe/kg, P = 0.02 and 19.8 ± 5.9 for IRON versus -0.8 ± 1.4 for T1-weighted MRA at 3.99 mgFe/kg, P = 0.0002). Similar results were obtained for vessel sharpness in peripheral vessels, (Vessel sharpness of 46.76 ± 6.48% for IRON versus 33.20 ± 3.53% for T1-weighted MRA at 1.71 mgFe/Kg, P = 0.002, and of 48.66 ± 5.50% for IRON versus 19.00 ± 7.41% for T1-weighted MRA at 3.99 mgFe/Kg, P = 0.003). CONCLUSION: Our study suggests that quantitative CNR and vessel sharpness after the injection of P904 are consistently higher for IRON MRA when compared with conventional T1-weighted MRA. These findings apply for a wide range of contrast agent dosages.
