Studies on Ag nanoparticles grown on Highly Ordered Pyrolytic Graphite (HOPG) using HREELS provide different results for smaller and larger particle sizes corresponding to Ag coverages below and above 4 monolayers, respectively. For the larger particles, a positive frequency shift with decreasing particle size and a broadening of the plasmon resonance were observed with decreasing particle size, in line with previous studies on Ag on alumina. For the smaller particles, in contrast, a shift to lower energy with decreasing particle size, and a narrowing of the plasmon resonance with decreasing particle size can be found. The asymmetry of the Ag-features present for Ag coverages above 4 monolayers disappears for Ag coverages below 4 monolayers. The result for the smaller particles can be rationalized in terms of change of the particle growth mode with increasing particle size, which corroborates our STM data, as well as electronic effects due to the metal/support charge transfer.
La antiguedad clasica como fuente y contexto en El esclavo en grillos de oro de Bances Candamo
( Ignacio Lopez Calvo ) 한국스페인어문학회 2006 스페인어문학 Vol.0 No.41
La antiguedad clasica sirve de trasfondo a la comedia El esclavo en grillos de oro en donde el dramaturgo aurisecular Francisco Bances Candamo(1662-1704)refleja sus inquietudes politicas. Con la presentacion de los enredos politicos del imperio romano, el dramaturgo asturiano consigue que el lector-espectador tome conciencia de la sombra amenazadora que acosa a la monarquia de Carlos II el Hechizado (1661-1700), dada la ausencia de heredero. La critica ha mencionado varios tratados destinados a la educacion de principes. Sin embargo, no se ha mencionado nunca un texto que parece haber tenido tambien mucha influencia en su obra: la Oracion a Nicocles, rey de Chipre, de Isocrates. En El esclavo en grillos de oro, ademas del esperado panegirico al rey, encontramos una osadia que acabaria costando muy cara a su autor. Como Isocrates, Bances Candamo tratade educar al rey para el buen gobierno e incluso se atreve a volver a mencionar el tema tabu de la sucesion. Al instar indirectamente al rey a que buscara un heredero para Espana, y al criticar a los allegados al emperador romano, la corte lo considero una afrenta tanto al rey como al privado de Carlos II. De hecho, tras ser herido en el pecho por un espectador que vio en El esclavo en grillos de oro un ataque al Conde de Oropesa, privado del rey, Bances Candamo se vio obligado, como se menciono anteriormente, a dejar su cargo y huir de Madrid por un tiempo.

Objective: The aim of this study was to evaluate the effect of dietary incorporation of tannin-rich woody species on meat oxidative stability, carcass traits and meat quality in goats. Methods: Two tannin-rich species were tested using a three-treatments feeding trial, where treatments consisted of: Larrea divaricata and Acacia aroma both at 12.5% in dry matter basis of the diet and a control diet (alfalfa hay). All feeding diets were iso-protein and iso-energy. Carcass conformation, carcass compactness, carcass fatness and subcutaneous fat deposition were evaluated. Intake, liveweigh, Longissimus thoracis et lumborum muscles of goats were analyzed in order to evaluate quality parameters such as pH value, instrumental color evaluation, water holding capacity, total phenolic content, antioxidant activity, meat oxidative stability and fatty acid profiles in meat. Results: Feed intake, liveweight gain, carcass, and meat traits did not differ among treatments. Changes in meat lipid profile among treatments were observed for oleic and elaidic acid contents. Meat total phenolic content and antioxidant activity did not differ among treatments; although, meat oxidative status after storage at room temperature, as well as under refrigerated and frozen conditions were different between control and both supplemented groups. Conclusion: The inclusion of Acacia aroma and Larrea divaricata leaves in goat diet enhanced meat oxidative stability. Modulation of the ruminal biohydrogenation of fatty acids produced by condensed tannins of these plant species need to be further investigated.

Purpose Association between body mass index (BMI) and doses in organs at risk during postoperative vaginal cuff brachytherapy (VCB) treatment has not been evaluated. The aim of this study was to analyse the impact of BMI on the dose delivered to bladder and rectum during high-dose-rate VCB using computed tomography (CT) scans at every fraction. Materials and Methods A retrospective analysis of 220 planning CT sets derived from 59 patients was conducted. Every planning CT was re-segmented and re-planned under the same parameters. Rectum and bladder dose-volume histogram values (D0.1cc, D1cc, and D2cc) were extracted and evaluated. The mean values for all applications per patient were calculated and correlated with BMI, as well as other factors influencing rectal and bladder doses. Multiple regression analysis performed to model organ at risk dose-volume parameters. Results According to World Health Organization (WHO), 6.8% of patients were normal, 35.6% were overweight, and 57.6% were class I obese. Median rectal doses were 133.5%, 110.9%, and 99.3% for D0.1cc, D1cc, and D2cc, respectively. The corresponding median bladder doses were 96.2%, 80.6%, and 73.3%, respectively. BMI did not show significant association with rectal doses. However, BMI did show a significant association with evaluated bladder dose metrics (D0.1cc, r=–0.366, p=0.004; D1cc, r=–0.454, p < 0.001; D2cc, r=–0.451, p < 0.001). BMI was retained in the multivariate regression models (D0.1cc, p=0.004; D1cc, p < 0.001; D2cc, p=0.001). Conclusion In this group of Mediterranean, overweight, and moderately obese patients, BMI showed association with lower bladder dose values, but not with rectal doses.

A 36 year-old man was referred to our hospital for the evaluation of an abnormal shadow on the cardiac apex on a chest X-ray fi lm.He denied systemic disease such as hypertension or diabetes mellitus and had no history of specifi c conditions, such as Kawasaki`s disease, chest trauma or connective tissue disorder. He had no subjective symptoms. His blood pressure was 120/75 mmHg and pulse rate was 70 beats/min. On physical examination, continuous murmur of a grade II/VI was audible at 4th left intercostal space. The results of other physical examination and blood test were normal. A Chest X-ray showed a radio-opaque shadow at the apex. An echocardiography was arranged and a round sac of 4x4 cm located in the apex, as well as a double-chamber right ventricle was observed Contrast echocardiography with Sonovue showed the fi lling of the vascular sac with contrast then partial fi lling of the distal RV apex. The abnormal vascular sac was connected from the left side to a vascular structure that looks to be coronary artery and from the right side to the distal part of a double right ventricle apex with a bi-directional shunt (fi stula). It also demonstrates the high velocity and centrifuge nature of blood fl ow in the vascular sac. Chest CT showed a LAD ectasia with a 4x4 cm saccular aneurysm at the distal portion of LAD Cardiac MRI revealed a giant left descending coronary artery distal aneurysm attached to a double apex right ventricle Coronary angiography revealed a dilated LAD with a huge saccular coronary aneurysm at its distal portion. The patient refused surgical correction for the coronary aneurysm and fi stula. He was discharged and has been followed up for more than 1 year without cardiovascular events.

Background: A biomarker that is of great interest in relation to adverse cardiovascular events is soluble ST2 (sST2), a member of the interleukin family. Considering that metabolic syndrome (MetS) is accompanied by a proinflammatory state, we aimed to assess the relationship between sST2 and left ventricular (LV) structure and function in patients with MetS. Methods: A multicentric, cross-sectional study was conducted on180 MetS subjects with normal LV ejection fraction as determined by echocardiography. LV hypertrophy (LVH) was defined as an LV mass index greater than the gender-specific upper limit of normal as determined by echocardiography. LV diastolic dysfunction (DD) was assessed by pulse-wave and tissue Doppler imaging. sST2 was measured by using a quantitative monoclonal ELISA assay. Results: LV mass index (β=0.337, P<0 .001, linear regression) was independently associated with sST2 concentrations. Increased sST2 was associated with an increased likelihood of LVH [Exp (B)=2.20, P=0.048, logistic regression] and increased systolic blood pressure [Exp (B)=1.02, P=0.05, logistic regression]. Comparing mean sST2 concentrations (adjusted for age, body mass index, gender) between different LV remodeling patterns, we found the greatest sST2 level in the group with concentric hypertrophy. There were no differences in sST2 concentration between groups with and without LV DD. Conclusions: Increased sST2 concentration in patients with MetS was associated with a greater likelihood of exhibiting LVH. Our results suggest that inflammation could be one of the principal triggering mechanisms for LV remodeling in MetS.
