No influence of oxygen levels on pathogenesis and virus shedding in Salmonid alphavirus (SAV)-challenged Atlantic salmon (Salmo salar L.)

2010

Abstract Background For more than three decades, diseases caused by salmonid alphaviruses (SAV) have become a major problem of increasing economic importance in the European fish-farming industry. However, experimental infection trials with SAV result in low or no mortality i.e very different from most field outbreaks of pancreas disease (PD). This probably reflects the difficulties in reproducing complex biotic and abiotic field conditions in the laboratory. In this study we looked at the relationship between SAV-infection in salmon and sub-lethal environmental hypoxia as a result of reduced flow-through in tank systems. Results The experiment demonstrated that constant reduced oxygen leve…

Automatic Seed Placement for Breast Lesion Segmentation on US Images

2012

Breast lesion boundaries have been mostly extracted by using conventional approaches as a previous step in the development of computer-aided diagnosis systems. Among these, region growing is a frequently used segmentation method. To make the segmentation completely automatic, most of the region growing methods incorporate automatic selection of the seed points. This paper proposes a new automatic seed placement algorithm for breast lesion segmentation on ultrasound images by means of assigning the probability of belonging to a lesion for every pixel depending on intensity, texture and geometrical constraints. The proposal has been evaluated using a set of sonographic breast images with acco…

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.

Tinea imbricata in Papua-Neuguinea: Behandlungsversuch mit Griseofulvin und Haloprogin bei einer Population des Gogol-Valley, Madang Province

2009

Zusammenfassung: In zwei Dorfern des Gogol Valley (Papua-Neuguinea) wurden satliche 47 an Tinea imbricata erkrankten Personen erfas, wovon 39 einer Griseofuhin®- bzw. Mycan-den®-Therapie oder Kombination zugefuhrt wurden. Die Zuweisung zu den unterschiedlichen Behandlungsgruppen erfolgte anhand des Alters und des prozentualen Befalls der Korperoberflache. Die Therapiedauer betrug maximal 4 Wochen, der Beobachtungszeitraum insgesamt 6 Wochen. Eine Remission des Hautbefalls erfolgte fur beide Therapeutika von der 2. Behand-lungswoche an. Rezidive traten jedoch schon 1 Woche nach Therapieende auf. Es konnten Unterschiede in der Altersverteilung der Erkrankten in beiden Dorfern festgestellt wer…

Liver haemangiomas undetermined at grey-scale ultrasound: contrast-enhancement patterns with SonoVue and pulse-inversion US.

2005

The objective of this study was to describe the spectrum of contrast-enhancement patterns of hepatic haemangiomas undetermined at grey-scale ultrasound (US) on SonoVue-enhanced pulse-inversion (PI) US. Twenty patients (11 women, nine men) with 35 haemangiomas (size range: 1-7 cm; mean: 3.1 cm) undetermined at baseline US underwent PI at low M.I. (0.05-0.08) after i.v. injection of SonoVue. All haemangiomas were confirmed by typical helical computed tomography (CT) and/or magnetic resonance imaging (MRI) findings. US examinations were videotaped and then reviewed by two experienced radiologists blinded to the final diagnosis. Readers evaluated by consensus the baseline echogenicity and the d…

Causas de la lesión de isquiosurales en fútbol: Una revisión bibliográfica desde las etapas formativas hasta la profesional

2021

espanolObjetivos: identificar las principales causas de lesion de isquiosurales en las diferentes etapas de formacion, desde la etapa sub-12 hasta la etapaprofesional, y establecer la influencia de la lesion previa de isquiosurales como causa principal de sufrir una nueva lesion.Metodo: la busqueda bibliografica se realizo en Dialnet, Pubmed, Web of Science, Scopus y SportDISCUS, entre las fechas de enero de 2010 hasta mayo de2020.Resultados: la busqueda concluyo que el patron de lesion isquiosural mas concurrido es el de jugador de edad avanzada, con mayores valores de fuerza ymenores valores de flexibilidad, y con un mayor grado de anteversion pelvica. El envejecimiento, los movimientos c…
