Three new species of Gromia (Protista, Rhizaria) identified from the Romanian Black Sea shelf.

The protist genus Gromia was first described in 1835 by Dujardin and while gromiids are prominent in the marine environment, Gromia oviformis was, for a long time, the only valid species regularly recorded. To date, 16 species that are morphologically and/or genetically distinct have been described. While recent studies are documenting their diversity and their ecological importance, G.

[Type B aortic dissection--endovascular stent-graft repair. Case report].

The treatment of aortic dissections type B Stanford using endovascular stents represents one of the newest advances in the treatment of this diseases, less invasive alternative to classic surgical repair. Aortic stent-grafts initially were used in treatment of abdominal aortic aneurysms, and then to treat aneurysms, dissections and traumatic ruptures of the descending aorta, with good early and mid-term outcomes. Thoracic aortic aneurysms are frequently diagnosed in mid-age or elderly patients who have arterial hypertension, coronary artery disease, chronic obstructive pulmonary disease.

Relationships between the degree and topography of the atherosclerotic lesions of the extracranial carotid axis with the clinical form of ischaemic attack, evaluated by duplex methodology.

Carotid echotomography (CET) in the duplex system was made in 118 patients with atherosclerotic lesions of various degree (insignificant stenoses--ISS; significant stenoses--SS and thromboses) of the extracranial carotid axis. The atherosclerotic lesions were localized mainly at the level of the carotid bifurcation (CB) and/or at the level of the carotid sinus. The clinical form of the ischaemic attack was better correlated with the extension of atherosclerotic lesions in the extracranial carotid axis than with the severity of these lesions.
