S100 proteins are small dimeric calcium-binding proteins which control cell cycle, growth and differentiation via interactions with different target proteins. Intrinsic disorder is a hallmark among many signaling proteins and S100 proteins have been proposed to contain disorder-prone regions. Interestingly, some S100 proteins also form amyloids: S100A8/A9… (More)
BACKGROUND Fabry disease is a lysosomal storage disease caused by enzyme α-galactosidase A deficiency as a result of mutations in the GLA gene. Cardiac involvement is characterized by progressive left ventricular hypertrophy. OBJECTIVE To estimate the prevalence of Fabry disease in a population with left ventricular hypertrophy. METHODS The patients… (More)
Zolmitriptan is a drug used in the acute treatment of migraine, which should not be used in high cardiovascular risk individuals because of its potential to induce vasospasm. We report a rare case of myocardial infarction precipitated by taking zolmitriptan.
Cells release vesicles to the extracellular environment with characteristic nucleic acid, protein, lipid, and glycan composition. Here we have isolated and characterized extracellular vesicles (EVs) and total cell membranes (MBs) from ovarian carcinoma OVMz cells. EVs were enriched in specific markers, including Tsg101, CD63, CD9, annexin-I, and MBs… (More)
Chest pain is one of the most frequent patient's complaints. The commonest underlying causes are well known, but, sometimes, in some clinical scenarios, it is necessary to consider other diagnoses. We report a case of a 68-year-old Caucasian male, chronically hypertensive, who complained of recurrent episodes of chest pain and fever with elevated acute… (More)
Tricuspid stenosis (TS) is an uncommon complication of transvenous ventricular pacemaker implantation, with few cases reported in the literature. The mechanisms described are obstruction of right ventricular inflow by tricuspid vegetations (endocarditis), multiple pacemaker leads and tricuspid valve (TV) fibrosis secondary to perforation or laceration of… (More)
