A 6-year-old, neutered male Labrador Retriever was diagnosed with congestive heart failure, and an echocardiogram revealed a large mass inside the pericardial sac associated with the left ventricle. At necropsy, the dog had marked ascites, mild hydrothorax, marked hydropericardium, and an 11.0 x 7.0 x 6.0 cm, tan and red, firm, well-demarcated mass attached to the left ventricular free wall. Th...

A 34-year-old woman with exertional dyspnoea and clinical diagnosis of mitral stenosis underwent echocardiographic evaluation. Moderate to severe rheumatic mitral stenosis was confirmed but an unsuspected mass lesion in the dilated left atrium attached to inter-atrial septum in fossa ovalis region was found. Although the attachment was in favour of myxoma, it was difficult to differentiate with...

A 41-year-old woman visited our plastic surgeon with complaints of a progressively enlarged lower backmass for months. The mass had become very tender recently. Her physical examination demonstrated a round, movable, solid mass over the lower back, about 8 cm 7 cm at its largest diameter (Fig. 1A). The tumor was excised and the mass had no attachment to bone or periosteum. The specimen included...

We present a case involving a rare form of cyanotic congenital heart disease in a 2-month-old neonate. The initial diagnosis was thought to be tricuspid dysplasia with right-to-left shunting through an interatrial communication. However, surgery showed the presence of a pedunculated mass that prolapsed into the tricuspid valve orifice, thereby causing severe obstruction to right ventricular fil...

SUMMARY Narrow site specificity in parasites is assumed to be associated with fitness benefits, such as higher reproductive success, although this is never quantified. We linked the body mass and combined mass of egg sacs of female copepods, Neobrachiella spinicephala, parasitic on the sandperch, Pinguipes brasilianus, to attachment sites on the host. Adult females attach permanently either on ...

Zur Unterstützung der Kommunikation in kollaborativen Lernumgebungen werden häufig Chats eingesetzt. Dabei unterstützen explizite Referenzierungen in Chatdiskussionen das direkte Erkennen von Zusammenhängen und ermöglichen die Darstellung in Diskussionssträngen sowie die anschließende Analyse der Diskursstruktur. Die Evaluation eines Universitätsseminars, in dem die Referenzierungsfunktionalitä...

Rice blast caused by Magnaporthe oryzae is a major disease. In the present study, we aimed to identify and evaluate the novel bacterial isolates from rice rhizosphere for biocontrol of M. oryzae pathogen. Sixty bacterial strains from the rice plant's rhizosphere were tested for their biocontrol activity against M. oryzae under in vitro and in vivo. Among them, B. amyloliquefaciens had significa...

Im vorliegenden Artikel wird ein Ansatz zur prozessorientierten Ermittlung von eGovernment-Anforderungen aus Unternehmenssicht entwickelt. Als Ergebnis einer explorativen Untersuchung können Merkmale von Unternehmenslagen identifiziert werden, die ausschlaggebend sind für technische und organisatorische Gestaltungsaspekte unternehmerischer Behördenkontakte. Aus den ermittelten Anforderungen wir...

We present the case of a 77-year-old Cambodian woman with a 3-day history of dyspnea on exertion. Physical examination revealed a murmur of mitral regurgitation and decompensated heart failure. The ECG was remarkable for atrial fibrillation with rapid ventricular response. Transthoracic echocardiography showed severe left atrial dilation, a large (5 8 cm) mobile mass attached to the anterior le...

In a single-degree-of-freedom weakly nonlinear oscillator subjected to periodic external excitation, a small-amplitude excitation may produce a relatively large-amplitude response under primary resonance conditions. Jump and hysteresis phenomena that result from saddle-node bifurcations may occur in the steady-state response of the forced nonlinear oscillator. A simple mass-spring-damper vibrat...
