Surgical Science (SS) , 2011, DOI: 10.4236/ss.2011.29101
Abstract: Penetrating abdominal trauma is the main cause of pancreatic lesions and delay in diagnosis or treatment can increase morbimortality. We present a case of acute necrohemorrhagic pancreatitis (ANHP) secondary to airgun injury associated with pulmonary embolism caused by the projectile in a 36 year old man. He underwent urgent surgery, appreciating pancreatic contusion but not visualizing the projectile, located by CT scan 3mm from the inferior vena cava. The patient underwent further surgery 48 hours later for necrosectomy and the insertion of an irrigation tube, due to ANHP after the migration of the projectile into the lung. This case underlines the clinical relevance of pancreatic lesion in patients with a penetrating abdominal trauma, the diagnostic difficulty and the surgical strategy, as well as the repercussions of the migration of a foreign body through the blood stream, crossing the right heart chambers and becoming lodged in the lung.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0058616
Abstract: Introduction HLA-B27 has a modifier effect on the phenotype of multiple diseases, both associated and non-associated with it. Among these effects, an increased frequency of clinical enthesitis in patients with Rheumatoid Arthritis (RA) has been reported but never explored again. We aimed to replicate this study with a sensitive and quantitative assessment of enthesitis by using standardized ultrasonography (US). Methods The Madrid Sonography Enthesitis Index (MASEI) was applied to the US assessment of 41 HLA-B27 positive and 41 matched HLA-B27 negative patients with longstanding RA. Clinical characteristics including explorations aimed to evaluate spondyloarthrtitis and laboratory tests were also done. Results A significant degree of abnormalities in the entheses of the patients with RA were found, but the MASEI values, and each of its components including the Doppler signal, were similar in HLA-B27 positive and negative patients. An increase of the MASEI scores with age was identified. Differences in two clinical features were found: a lower prevalence of rheumatoid factor and a more common story of low back pain in the HLA-B27 positive patients than in the negative. The latter was accompanied by radiographic sacroiliitis in two HLA-B27 positive patients. No other differences were detected. Conclusion We have found that HLA-B27 positive patients with RA do not have more enthesitis as assessed with US than the patients lacking this HLA allele. However, HLA-B27 could be shaping the RA phenotype towards RF seronegativity and axial involvement.

PIER , 2011, DOI: 10.2528/PIER11012805
Abstract: In this paper, the characteristics of three different types of high impedance surfaces (HIS) to be used as ground planes for low profile wire antennas are investigated and compared: a mushroom-like surface, which is the classical example of HIS with connecting vias, and two surfaces with no vias, one of which is anisotropic. Both the simulation results and the measurements verify that the high impedance behaviour is successfully accomplished around the resonant frequency. In order to complete the study, return loss and radiation pattern of a horizontal dipole placed above the surfaces are analyzed.
Analytical Dispersion Characteristic of a Gap-Groove Waveguide

PIER M , 2011, DOI: 10.2528/PIERM11020806
Abstract: A new type of waveguide based on the gap waveguide concept is here proposed and called gap-groove waveguide. Its design is based on the realization of a groove on a metal, facing an artificial surface which creates a high impedance surface (HIS) boundary condition. This condition is achieved here by employing a structure of closely packed metallic pins, known as bed of nails. The type of modes that can propagate in the gapgroove waveguide are similar to the ones of a standard waveguide but in this case there is no need of electrical connection. This is a potential advantage, especially when working at high frequencies. The dispersion characteristic of the gap-groove waveguide is derived by solving an eigenvalue problem, settled through a resonance condition at the interface between the groove and the bed of nails. The eigenvalues are associated with the modes propagating in the waveguide, and their dispersion characteristic is analyzed and compared with full wave simulations. A procedure to maximize the bandwidth is also provided, based on an appropriate choice of the geometrical parameters. Furthermore, the field distribution and the modal impedance of the fundamental mode are investigated.

Alasbimn Journal , 2001,
Abstract: For many years, PET has been exclusively a University-based research modality. However, PET can provide unique clinical information in a viable manner with high diagnostic accuracy that affects patient management.The possibility to get user-friendly cyclotrons and automated synthesisers for key radiopharmaceuticals such as FDG, that can be shipped to remote PET centres, and the coverage for this expensive test, have facilitated the creation of regional distribution centres for FDG.Centro Andaluz de Diagnóstico PET (CADPET), has installed the first regional distribution centre for FDG in Andalucía (Spain) following Good Manufacturing Practice (GMP) rules (1).In this work, we describe the time spend since the creation of the Company until the finish of the installation, economic aspects, and mainly matters related to the design of the Facility, equipments installed and description of the production process.
Ideally Hard Struts to Achieve Invisibility
Jose-Manuel Fernandez Gonzalez;Eva Rajo-Iglesias;Manuel Sierra-Castaner
PIER , 2009, DOI: 10.2528/PIER09102603
Abstract: In this work, ideally hard struts with different cross sections are analyzed. Firstly, the characterization of the invisibility of a given object in terms of an equivalent blockage width is discussed. Then, the effect of the incidence angle on struts for reducing electromagnetic blockage using the same ideally hard cylinders is analyzed. It is shown that the variation of incidence angle in azimuth is very sensitive in terms of blockage for both polarizations. Finally, design charts for ideally hard struts which reduce blockage simultaneously for TE and TM cases are presented. This can be used to define some performance goals for final realized struts.
Back Radiation Reduction in Patch Antennas Using Planar Soft Surfaces

PIER Letters , 2009, DOI: 10.2528/PIERL08111202
Abstract: In this work, we propose to use a type of periodic structures, the soft surfaces in their planar version, to reduce the back radiation of patch antennas. A key aspect of these surfaces when compared to other periodic structures is their anisotropy which provides different behaviour for different field polarization (horizontal or vertical). This make them especially convenient for this application, as the soft surfaces force the field intensity for any polarization to be zero on the surface for waves propagating along the surface. In this paper, a design example is presented and the back radiation reduction by using planar soft surfaces is demonstrated.

Revista de la Sociedad Química de México , 2005,
Abstract: A convenient pathway to obtain 3β-hydroxy-6-oxo-5α-steroids from 3β-acetoxy 5-steroids is reported; the methodology was applied to the synthesis of laxogenin (7), substance that behaves as a plant growth hormone. This is an alternative way to produce an important functionality found in many examples of naturally occurring steroids. The developed procedure uses inexpensive reagents and can be carried out in four steps. The oxidizing and acidic steps used in this methodology did not affect the labile spiroketal side chain present in diosgenin (16).
