Medullary Schistosomiasis

BACKGROUND: Schistosomal infestation of the central nervous system is a rare cause of cord compression, although a predominant one in endemic areas. CASE DESCRIPTION: A 38-year-old male, native of Ivory Coast, with a history of 1 month of progressive paraparesis, neurogenic bladder, diminished deep tendon reflexes of the lower limbs, and sensory level. The magnetic resonance imaging (MRI) showed a medullary le...

New dextrin nanomagnetogels as contrast agents for magnetic resonance imaging

This study aims at the production and characterization of a “nanomagnetogel” consisting of superparamagnetic iron oxide nanoparticles (g-Fe2O3) stabilized within a hydrophobized-dextrin nanogel. The nanomagnetogel obtained was extensively characterized with respect to physico-chemical (transmission electron microscopy, cryo-scanning electron microscopy, dynamic light scattering, small angle X-ray scattering), m...

Improving fECG signal acquisition in the evaluation of fetal well-being

The ability to monitor fetal heart rate is vital during late pregnancy and labor in order to evaluate fetal well-being. Current monitoring practice is essentially based on external cardiotocography and, less frequently, during labor, invasive fetal scalp electrocardiography. Many current and envisaged applications could benefi t from simpler devices using a 3-lead ECG confi guration. We are designing a maternit...

IFNAR1 Controls Progression to Cerebral Malaria in Children and CD8+ T Cell Bra...

Malaria in pregnancy is exquisitely aggressive, causing a range of adverse maternal and fetal outcomes prominently linked to Plasmodium-infected erythrocyte cytoadherence to fetal trophoblast. To elucidate the physiopathology of infected erythrocytes (IE) sequestration in the placenta we devised an experimental system for intravital placental examination of P. berghei-infected mice. BALB/c females were mated to...

Assessment of sediment contamination in an impacted estuary: differential effec...

Conferência realizada em Lisboa, de 6-9 November de 2013 ; Estuarine pollution is reflected in the concentration of toxicants in sediments, depending on their geochemical properties, since sediments trap substances from the water column, either dissolved or bound to suspended matter. However, determining risk of sediment contaminants to biota has many constraints. For such reason, integrative approaches are ke...

Desenvolvimento vocacional no ensino superior: o foco em estudantes do 1º ano

Utilização de bioindicadores na monitorização e certificação da qualidade do ol...

A intensificação das práticas agrícolas com recurso, na maioria das vezes, a aplicações de pesticidas e a mobilizações e fertilizações frequentes do solo, têm como consequência a degradação dos recursos naturais e a perda de biodiversidade nos agroecossistemas. Por outro lado, os efeitos destas práticas têm sido estudados nas últimas décadas e, devido aos seus impactes negativos, os agricultores têm sido encora...

Sodium Content in Vegetable Soups Prepared Outside the Home: Identifying the Pr...

Cardiovascular diseases are a major cause of mortality and disability in developed countries, accounting for 39% of deaths. One of the most important factors associated with their onset is a high sodium intake, which increases the risk of high blood pressure. Excessive salt intake is associated with the consumption of processed foods and eating outside home, which nowadays can vary from one to all day meals. Th...
