A farmer's wife who had helped with lambing aborted spontaneously in March after a short febrile illness in the 28th week of her pregnancy. She developed disseminated intravascular coagulation post partum with acute renal failure and pulmonary oedema. Recovery was complete after two weeks of hospital care. A strain of Chlamydia psittaci, probably of ovine origin, was isolated from the placenta ...
Impaired nitric oxide-cGMP signaling contributes to severe pulmonary hypertension after birth, which may in part be due to decreased soluble guanylate cyclase (sGC) activity. Cinaciguat (BAY 58-2667) is a novel sGC activator that causes vasodilation, even in the presence of oxidized heme or heme-free sGC, but its hemodynamic effects have not been studied in the perinatal lung. We performed surg...
Pulmonary endarterectomy (PEA) is a well-established procedure in the treatment of chronic thromboembolic pulmonary hypertension (CTPH). The procedure is known to increase functional outcome and to raise the 5-year survival rate. We report 2 cases of pulmonary valve endocarditis and secondary embolisms causing sustained pulmonary hypertension. Both were treated with PEA. In none of the cases, a...
Percutaneous pulmonary valve replacement is one of the most important advancements in the field of interventional cardiology in the past decade.1,2 However, currently available technologies are not applicable to patients with oversized right ventricular outflow tracts (RVOTs), especially when there is concomitant proximal branch pulmonary artery (PA) stenosis. This combination commonly is encou...
Jaagsiekte sheep retrovirus (JSRV) is the causative agent of ovine pulmonary carcinoma, a unique animal model for human bronchioalveolar carcinoma. We previously isolated a JSRV proviral clone and showed that it was both infectious and oncogenic. Thus JSRV is necessary and sufficient for the development of ovine pulmonary carcinoma, but no data are available on the mechanisms of transformation....
Ovine pulmonary adenocarcinoma (OPA) is a lung cancer strikingly similar to the pneumonic-type mixed invasive adenocarcinoma with a predominant bronchioloalveolar component in humans. Telomerase activity in OPA and the potential involvement of the kinase Akt in telomerase activation and regulation of cell proliferation were investigated. Lung tissues were collected from sheep with a histopathol...
BACKGROUND The applications of proteomic strategies to ovine medicine remain limited. The definition of serum proteome may be a good tool to identify useful protein biomarkers for recognising sub-clinical conditions and overt disease in sheep. Findings from bovine species are often directly translated for use in ovine medicine. In order to characterize normal protein patterns and improve knowle...
The endogenous retroviruses are inherited elements transmitted trough the germline of most animal species and their biological role is still controversial. Ovine Pulmonary Carcinoma (OPC) represents a good model for studying the interactions of endogenous retroviruses with their exogenous counterparts. The type D exogenous retrovirus known as Jaagsiekte Sheep Retro-Virus (JSRV) is necessary and...
Ovine pulmonary adenocarcinoma (OPA) is a transmissible lung cancer of sheep caused by jaagsiekte sheep retrovirus (JSRV). In the present study the protein profiles of five neoplastic and three non-neoplastic sheep lung tissues were examined for the identification of proteins overexpressed in ovine pulmonary adenocarcinoma. Lung sections of the experimental group of sheep were collected during ...
The literature indicates that vasoactive substances released from platelets contribute to the pulmonary pressor response and hypoxemia during pulmonary microembolism. Hence, removal of the platelets or inhibition of their function should reduce these effects. The purpose of this study was, therefore, to investigate the pulmonary effects of experimental embolism with glass beads in dogs rendered...
