Lesion Segmentation in Breast Sonography

2010

Sonography is gaining popularity as an adjunct screening technique for assessing abnormalities in the breast This is particularly true in cases where the subject has dense breast tissue, wherein widespread techniques like Digital Mammography (DM) fail to produce reliable outcomes This article proposes a novel and fully automatic methodology for breast lesion segmentation in B-mode Ultra-Sound (US) images by utilizing region, boundary and shape information to cope up with the inherent artifacts present in US images The proposed approach has been evaluated using a set of sonographic images with accompanying expert-provided ground truth.

Fanconi's anaemia cells have normal steady-state levels and repair of oxidative DNA base modifications sensitive to Fpg protein

1998

Abstract Cells from Fanconi's anaemia (FA) patients are abnormally sensitive to oxygen. However, a distinct genetic defect in either the cellular defence against reactive oxygen species (ROS) or in their metabolic generation has not been identified to date. Recently, the gene for the human 8-hydroxyguanine (8-oxoG) glycosylase, which removes this oxidative base modification from the genome, has been localized on chromosome 3p25, i.e., in the same region as the FA complementation group D (FAD) gene. We therefore studied the removal of photosensitization-induced 8-oxoG residues from the DNA of FA cells, using Fpg protein, the bacterial 8-oxoG glycosylase, to quantify the lesions by alkaline e…

Calidad de la atención al paciente oncológico: Tiempos asistenciales recomendables entre sospecha clínica y definición del plan terapéutico en cáncer…

2012

Fundamento. Determinar tiempos recomendables para el tratamiento desde la sospecha clínica fundada en los procesos asistenciales de cáncer de mama y colorrectal considerando factibilidad y situación personal del paciente. Método. Estudio cualitativo de búsqueda de consenso entre profesionales. Primero, se revisaron mediante 4 sesiones grupales (N=19), los procesos asistenciales de cáncer de mama y cáncer colorrectal y se fijaron los tiempos deseables de ambos procesos. Segundo, mediante una modificación de la técnica Delphi (N=49), se validó la propuesta de tiempos de atención recomendables para cada proceso asistencial. Resultados. La tasa de respuesta en el estudio Delphi fue del 69% en e…

Elektronenmikroskopische Zytomorphologie der m�nnlichen Brustdr�se

1969

Im Vergleich zu lichtmikroskopischen Untersuchungen an der Mamma virilis wird anhand von 2 operativ entfernten Brustdrusen eines 57 und 63 Jahre alten Mannes die elektronenmikroskopisch erfasbare Zytomorphologie beschrieben. Die Befunde werden den physiologischen Wachstumsimpulsen dieses Organs gegenubergestellt und Fragen der Zelldifferenzierung, der Desquamation und apokrinen Sekretion beantwortet. Elektronenmikroskopisch werden am Drusenepithel Basalzellen, grosere Zellen der oberflachlichen Zellreihen und Myoepithelzellen unterschieden. Diese Zellen entsprechen den Gangepithelien der weiblichen Brustdruse und besitzen intracytoplasmatische Filamente. Diese stellen ein haufiges Differenz…

Is morphokinetic analysis the answer?

2013

Abstract Efforts aimed at improving pregnancy rates have focused on the search for additional markers of viability to supplement current criteria for embryo selection. Time-lapse technology represents a powerful tool in assisted reproduction for evaluating embryos dynamically. Whilst standard methods of embryo assessment are based on subjective morphology evaluation at discrete time points, thereby limiting the information produced for embryo selection, time-lapse recording introduces several additional morphokinetic parameters for embryo evaluation. This additional information can improve implantation rates and reproductive outcomes. This review surveys available knowledge on time-lapse im…

Species Diversity and Distribution of Mammals in Riga

2003

The aim of this study was to investigate the species diversity and distribution of mammals in the territory of Riga. Our specific aims were to create a zonal division of Riga, and to classify habitats in unbuilt areas of the city. Riga was divided into four zones according to historical, economic and geographical features. Criteria of habitat classification were as follows: the size of a territory, anthropogenic load, soil and vegetation types and age. Sixteen types of habitats were distinguished. In the period 1999–2002, 27 mammal species of six orders were registered in the investigated territory of Riga. The number of animals and the diversity of species increased towards the periphery o…

Modulation of N···I and +N−H···Cl−···I Halogen Bonding: Folding, Inclusion, and Self-Assembly of Tri- and Tetraamino Piperazine Cyclophanes

2010

The acidity of the crystallization conditions was successfully employed in modulating the balance between the robust intramolecular hydrogen bonding (HB) and intermolecular halogen bonding (XB) observed in large tri- (1) and tetraamino (2) piperazine cyclophanes. A careful crystallization of the title XB acceptor cyclophanes with a strong bidentate XB donor 1,4-diiodotetrafluorobenzene (F4DIB) from CHCl3:MeOH, dimethylformamide (DMF), or HCl:H2O:EtOH resulted in X-ray quality crystals of 1·F4DIB, 2@DMF, 2·2@F4DIB, [1H3]Cl3·(F4DIB)6, and [2H6]Cl6·(F4DIB)2. The intramolecular hydrogen bonding pattern in 1 and 2 was retained in neutral protic and aprotic solvents, and regular N−H···N hydrogen …

Percepciones sobre «lo oriental» en el arte valenciano: el caso de los Baños del Almirante

2017

Resumen: El presente artículo trata la percepción de «lo oriental», algo muy actual en los tiempos que vivimos, sobre todo tras los altercados del 11 de septiembre del 2001, donde se reabrió la caja de Pandora en la visión negativa gestada de la sociedad musulmana. Abordaremos para ello la imagen del hammam, elemento patrimonial de la geografía española, centrando la investigación en el caso de los Baños del Almirante de Valencia, etiquetados erróneamente durante tiempo por la historiografía como islámicos, siendo en realidad cristianos. Abstract: The present article deals with the perception of «the oriental», a relevant topic nowadays, especially after the events of 11 September 2001, whe…

Smoking cessation opportunities in severe mental illness (tobacco intensive motivational and estimate risk — TIMER—): study protocol for a randomized…

2019

There is an increased risk of premature death in people with severe mental illness (SMI). Respiratory disorders and cardiovascular disease are leading causes of increased mortality rates in these patients, and tobacco consumption remains the most preventable risk factor involved. Developing new tools to motivate patients towards cessation of smoking is a high priority. Information on the motivational value of giving the lung age and prevention opportunities is unknown in this high-risk population. In the context of community care, screening and early detection of lung damage could potentially be used, together with mobile technology, in order to produce a prevention message, which may provi…
