José Ricardo Morales y La Celestina
El artículo aborda la recpeción crítica del montaje que José Ricardo Morales realizó de La Celestina en 1949 con el Teatro Experimental de la Universidad de Chile a partir de una adaptación propia. En octubre de 1949 Margarita Xirgu estrenaba con la Comedia Nacional de Uruguay, en el Teatro Solís de Montevideo, la versión de La Celestina que le había encomendado a José Ricardo Morales, joven dramaturgo español por entonces exiliado en Chile. Apenas un mes después, en noviembre de ese mismo año, Morales daba a conocer su propia puesta en escena de la obra en el Teatro Municipal de Santiago, al frente del Teatro Experimental de la Universidad de Chile, del que había sido uno de sus fundadores
Traumatic Dental Injuries: Clinical Case Presentation and a 10-Year Epidemiological Investigation in an Italian Dental Emergency Service
Traumatic dental injuries (TDIs) are very common in the world population, and international literature reports several studies which helped in the definition of international guidelines. The aim of this study is to present two clinical cases of TDI and to investigate epidemiological and etiological aspects of TDIs in patients treated in Modena, Italy, between January 2010 and December 2020. The presented case reports are two explicative clinical cases of successful TDI management with a long-Term follow-up. The epidemiological analysis was performed on patients who visited the Dental Emergency Service of the Dentistry and Oral-Maxillo-Facial Surgery Unit of Modena (Italy) over a period of 10 years. Data relating to age, gender, type of trauma, and place of accident were collected. Five-hundred-sixty-five TDIs that occurred to patients from 1 to 68 years old were reported, with a total of 860 injured teeth. The peak age at which TDIs are most represented varies between 2 and 3 years old, and they occurred frequently from 1 up to 7 years old. 57.5% were male, while 42.5% were female. The most common trauma resulted to be the uncomplicated crown fracture (20%), immediately followed by lateral luxation (19%), intrusive luxation (18%), avulsion (17%), and complicated crown fracture (15%). TDIs occurred at home in 44% of cases. The need for more prevention training must be highlighted, due to the fact that many TDIs occur at home and in a preschool age
Roturas tendinosas y musculares en el hombro del deportista
El complejo articular del hombro está sometido
a solicitaciones mecánicas en la mayoría
de las modalidades deportivas; así el 10-15%
de los traumatismos sufridos por los atletas
afectan a esta articulación (1). La "patología
reina" del hombro del deportista es la inestabilidad,
por su frecuencia, importantes implicaciones
funcionales y tratamiento problemático. Por
el contrario, las roturas musculares y tendinosas
del hombro son lesiones poco frecuentes en
el deportista pero no por ello irrelevantes, pues
pueden provocar una gran incapacidad para
seguir desempeñando el mismo deporte y al
mismo nivel de competición si no se hace un
tratamiento correcto, a pesar del cual a veces
los resultados no son satisfactorios. Es decir,
pueden representar el "principio del fin" de la
actividad deportiva. Tibone y cols. (2) en un
estudio realizado sobre tratamiento quirúrgico
de roturas del manguito de los rotadores en
atletas, encuentran que sólo el 32% de los jugadores
de baseball profesionales tratados por
ellos volvían a jugar en la liga profesional
americana después de su lesión
Hypersensitivity in molar incisor hypomineralization: Superficial infiltration treatment
To date, there are no standardized protocols available in the literature for hypersensitivity treatment in molar incisor hypomineralization (MIH) patients. The aim of this study was to evaluate the efficacy of erosion\u2013infiltration treatments with resin in children with a strong hypersensitivity and also to develop a minimally invasive diagnostic\u2013therapeutic pathway for young MIH patients. Patients with clinical signs of MIH were enrolled according to international guidelines. A total of 42 patients (8\u201314 years old) with sensitivity of at least one molar and patients with post eruptive enamel fractures, but without dentin involvement or cavitated carious lesions were selected. A single superficial infiltration treatment with ICON (DMG, Germany) was performed with a modified etching technique. Sensitivity was tested with the Schiff Scale and Wong Baker Face Scale and was repeated at 12 months follow\u2010up. All patients reported lower sensitivity values at the end of the treatment. Significant differences of sensitivity according to the Schiff scale were reported between T0 and all subsequent follow\u2010ups, p < 0.05. The treatment of erosion infiltration with ICON resin is a minimally invasive preventive treatment that significantly improves the problem of hypersensitivity in permanent molars with MIH
Amorphous FeCoCrSiB Ribbons with Tailored Anisotropy for the Development of Magnetic Elements for High Frequency Applications
The ferromagnetic resonance (FMR) in the frequency range of 0.5 to 12.5 GHz has been investigated as a function of external magnetic field for rapidly quenched Fe3Co67Cr3Si15B12 amorphous ribbons with different features of the effective magnetic anisotropy. Three states of the ribbons were considered: as-quenched without any treatment; after relaxation annealing without stress at the temperature of 350 °C during 1 h; and after annealing under specific stress of 230 MPa at the temperature of 350 °C during 1 h. For FMR measurements, we adapted a technique previously proposed and tested for the case of microwires. Here, amorphous ribbons were studied using the sample holder based on a commercial SMA connector. On the basis of the measurements of the reflection coefficient S11, the total impedance including its real and imaginary components was determined to be in the frequency range of 0.5 to 12.5 GHz. In order to confirm the validity of the proposed technique, FMR was also measured by the certified cavity perturbation technique using a commercial Bruker spectrometer operating at X-band frequency of 9.39 GHz. As part of the characterization of the ribbons used for microwave measurements, comparative analysis was performed of X-ray diffraction, optical microscopy, transmission electron microscopy, inductive magnetic hysteresis loops, vibrating sample magnetometry, magneto-optical Kerr effect (including magnetic domains) and magnetoimpedance data for of all samples.The research funding from the Ministry of Science and Higher Education of the Russian Federation (Ural Federal University Program of Development within the Priority-2030 Program) is gratefully acknowledged.

Clinical and Histopathologic Characteristics of the Main Causes of Vascular Occusion — Part II: Coagulation Disorders, Emboli, and Other
La patología vascular oclusiva es causante de diversas y variadas manifestaciones clínicas, algunas de ellas con catastróficas consecuencias para el paciente. Dado que las causas de tal oclusión son muy variadas, hemos abordado en un artículo previo reciente en esta misma revista las causas trombóticas. En el presente artículo recopilamos diversas causas adicionales de oclusión intravascular.Vascular occlusion has multiple, diverse clinical manifestations, some of which can have grave consequences for patients. It also has a wide variety of causes, including thrombi, which we recently addressed in part I of this review. In this second part, we look at additional causes of vascular occlusion
MAGIC Upper Limits for two Milagro-detected, Bright Fermi Sources in the Region of SNR G65.1+0.6
We report on the observation of the region around supernova remnant G65.1+0.6
with the stand-alone MAGIC-I telescope. This region hosts the two bright GeV
gamma-ray sources 1FGL J1954.3+2836 and 1FGL J1958.6+2845. They are identified
as GeV pulsars and both have a possible counterpart detected at about 35 TeV by
the Milagro observatory. MAGIC collected 25.5 hours of good quality data, and
found no significant emission in the range around 1 TeV. We therefore report
differential flux upper limits, assuming the emission to be point-like (<0.1
deg) or within a radius of 0.3 deg. In the point-like scenario, the flux limits
around 1 TeV are at the level of 3 % and 2 % of the Crab Nebula flux, for the
two sources respectively. This implies that the Milagro emission is either
extended over a much larger area than our point spread function, or it must be
peaked at energies beyond 1 TeV, resulting in a photon index harder than 2.2 in
the TeV band.Comment: 8 pages, 3 figures, 1 tabl
P34 98. Leiomiomatosis con diseminación intravascular: Desde el útero a cavidades cardíacas y pulmón
ObjetivosLa leiomiomatosis uterina es un tumor mesenquimal poco frecuente, benigno, caracterizado por la proliferación de músculo liso en la luz vascular. Suele presentarse en mujeres de edad media, y presenta una enorme tendencia a la extensión intravascular y cardíaca. El tratamiento principalmente es quirúrgico para reducción de la masa tumoral, asociándose un bloqueo hormonal.MétodoPresentamos el caso de una mujer de 39 años, asintomática, con una plaquetopenia en estudio. Al realizarse una ecografía abdominal, se detecta una tumoración uterina de gran tamaño. La tomografía computarizada toracoabdominal objetivó extensión intravascular, a través de vena cava, extensión cardíaca hasta aurícula y ventrículo derecho, válvula tricúspide y arteria pulmonar hasta lechos parenquimatosos pulmonares.El tratamiento incluyó la realización de una histerectomía y doble anexectomía, asociándose una resección tumoral con acceso abdominal por laparotomía media desde cava inferior, y cirugía cardíaca con parada cardiocirculatoria, hipotermia profunda y perfusión anterógrada vía axilar, para resección tumoral intracardíaca.ResultadosLa evolución postoperatoria fue favorable. El estudio anatomopatológico diagnosticó una leiomiomatosis uterina con diseminación intravascular y cardíaca.ConclusionesLa leiomiomatosis uterina es una tumoración benigna con enorme tendencia a la extensión intravascular y cardíaca. Su tratamiento incluye resección tumoral y bloqueo hormonal de por vida, en mujeres jóvenes, generalmente. El tratamiento quirúrgico para resección tumoral exige control eco-cardiográfico para comprobar la completa resección del mismo
Manejo do dossel vegetativo e seu efeito nos componentes de produção da videira Merlot.
A poda verde é uma prática cultural utilizada para melhorar as condições do dossel vegetativo dos vinhedos, visando a favorecer a qualidade da uva e do vinho. Nesse sentido, realizou-se este experimento entre as safras de 1993/1994 e 1996/1997, com diferentes modalidades de poda verde, num vinhedo do cv. Merlot conduzido em latada. Houve 12 tratamentos e três repetições, sendo o delineamento experimental em blocos casualizados. Os tratamentos constituíram-se da testemunha e de 11 diferentes modalidades de poda verde, ou seja, desbrota, desponta e desfolha, algumas delas em diferentes épocas do ciclo vegetativo da videira. O componente principal 1, da análise de componentes principais (ACP) feita em cada ano, separadamente, mostra que o tratamento 10 (desbrota + desponta + desfolha realizada no início da floração, eliminando-se as folhas abaixo dos cachos) discriminou-se nos quatro anos, e os tratamentos 7 (desfolha realizada 21 dias antes da colheita, eliminando-se metade das folhas abaixo dos cachos) e 6 (desfolha realizada 21 dias antes da colheita, eliminando-se as folhas abaixo dos cachos), em três deles; a ACP da média dos quatro anos também evidencia essa discriminação entre eles. Constata-se que o tratamento 10 foi um dos que tiveram intensidade de poda verde mais intensa, caracterizando-se por variáveis indicativas de plantas com vigor e produtividade mais baixos que os demais
