Schistosomiasis associated with rupture of the appendix in pregnancy.

Numai utilizatorii înregistrați pot traduce articole

Acute appendicitis is among the most common indications for exploratory laparotomy during pregnancy. Although usually pyogenic in origin, parasitic infections account for a small percentage of cases. We report here the association of pregnancy and appendicitis caused by Schistosoma japonicum.

Cardiopulmonary disease in Manson's schistosomiasis.

Numai utilizatorii înregistrați pot traduce articole

Five patients with cardiopulmonary manifestations of Manson's schistosomiasis are described. Two patients had pulmonary hypertension, two had cyanosis and one had the very rare combination of both. The results of routine pulmonary function tests--not sufficiently studied in this form of

Hypoxia, hypoxia-inducible factor-1α and vascular endothelial growth factor in a murine model of Schistosoma mansoni infection.

Schistosomiasis mansoni is a chronic parasitic disease where much of the symptomatology is attributed to granuloma formation, an immunopathological reaction against Schistosoma eggs. To more clearly understand the immunopathology of schistosomiasis, the tissue microenvironment generated by S.

TGF-β activation by bone marrow-derived thrombospondin-1 causes Schistosoma- and hypoxia-induced pulmonary hypertension.

Numai utilizatorii înregistrați pot traduce articole

Pulmonary arterial hypertension (PAH) is an obstructive disease of the precapillary pulmonary arteries. Schistosomiasis-associated PAH shares altered vascular TGF-β signalling with idiopathic, heritable and autoimmune-associated etiologies; moreover, TGF-β blockade can prevent experimental pulmonary

Studies on survival, biological activities and behavior of Biomphalaria glabrata, the host snail of schistosomiasis, submitted to increased hydrostatic pressure: a technique.

Numai utilizatorii înregistrați pot traduce articole

To study changes in survival, in biological activities and behavior of planorbids submitted to increased hydrostatic pressure, we developed a technique using two transparent chambers and a hydraulic piston. The apparatus permitted renewal of the liquid medium without substantial variations in

Definition, classification, and epidemiology of pulmonary arterial hypertension.

Numai utilizatorii înregistrați pot traduce articole

Pulmonary arterial hypertension (PAH) is a distinct subgroup of pulmonary hypertension that comprises idiopathic PAH, familial/heritable forms, and PAH associated with connective tissue disease, congenital heart disease, portal hypertension, human immunodeficiency virus (HIV) infection, and some

Pulmonary hypertension (PH) is a progressive disease that if left untreated, has very high morbidity and mortality due to right-sided heart failure. Pulmonary hypertension falls into five separate World Health Organization (WHO) groups based on the etiology, which has important ramifications for

Rigidity and resistance of larval- and adult schistosomes-medium interface.

Schistosomiasis is second only to malaria in prevalence and severity, and is still a major health problem in many tropical countries worldwide with about 200-300 million cases and with more than 800 million people at risk of infection. Based on these data, the World Health Organization recommends

(99m)Technetium-macroaggregated albumin perfusion lung scan versus contrast enhanced echocardiography in the diagnosis of the hepatopulmonary syndrome in children with chronic liver disease.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE The hepatopulmonary syndrome (HPS) is a triad of advanced chronic liver disease (CLD), arterial hypoxemia and intrapulmonary arteriovenous shunting in the absence of a primary cardiopulmonary disease. HPS has been more frequently reported in adults than in children with no data on its

Evaluation of normality and reproducibility parameters of scintigraphy with (99m)Tc-MAA in the diagnosis of intrapulmonary vascular dilatations.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The formation of intrapulmonary vascular dilations (IPVD) is the key event for the onset of hepatopulmonary syndrome, vascular changes secondary to portal hypertension that leads to hypoxemia. The diagnosis of IPVD can be made by contrasted transthoracic echocardiography or scintigraphy

Macrophage arginase-1 controls bacterial growth and pathology in hypoxic tuberculosis granulomas.

Numai utilizatorii înregistrați pot traduce articole

Lung granulomas develop upon Mycobacterium tuberculosis (Mtb) infection as a hallmark of human tuberculosis (TB). They are structured aggregates consisting mainly of Mtb-infected and -uninfected macrophages and Mtb-specific T cells. The production of NO by granuloma macrophages expressing nitric

Experimental and transgenic models of pulmonary hypertension.

Numai utilizatorii înregistrați pot traduce articole

Pulmonary hypertension in human patients can result from increased pulmonary vascular tone, pressure transferred from the systemic circulation, dropout of small pulmonary vessels, occlusion of vessels with thrombi or intimal lesions, or some combination of all of these. Different animal models have

Paclitaxel blocks Th2-mediated TGF-β activation in Schistosoma mansoni-induced pulmonary hypertension.

Numai utilizatorii înregistrați pot traduce articole

Schistosomiasis is a leading cause of pulmonary hypertension (PH) worldwide. Recent studies reveal that the type-2 immune cytokines IL-4 and IL-13, as well as consequent activation of TGF-β, are key factors in the pathogenesis of Schistosoma-PH. Paclitaxel has been reported to act as an adjuvant for
