Cerebral venous thrombosis in Argentina: clinical presentation, predisposing factors, outcomes and literature review.

Background: Cerebral venous thrombosis (CVT) is a rare medical condition that primarily affects young adults. The clinical spectrum is broad and its recognition remains a challenge for clinicians. Limited information is available on CVT in Argentina.

Eye-Movement Training Results in Changes in qEEG and NIH Stroke Scale in Subjects Suffering from Acute Middle Cerebral Artery Ischemic Stroke: A Randomized Control Trial.

Context: Eye-movement training (EMT) can induce altered brain activation and change the functionality of saccades with changes of the brain in general.

Objective: To determine if EMT would result in changes in quantitative electroencephalogram (qEEG) and NIH Stroke Scale (NIHSS) in patients suffering from acute middle cerebral artery (MCA) infarction. Our hypothesis is that there would be positive changes in qEEG and NIHSS after EMT in patients suffering from acute MCA ischemic stroke.

Selective isolation of multiply charged peptides: a confident strategy for protein identification using a linear trap quadrupole mass spectrometer.

In this work, a method devised for the selective isolation of multiply-charged peptide applied to a complex protein mixture was evaluated for the first time using a mass spectrometer with low resolution (LTQ). In this procedure, all primary amino groups of tryptic peptides derived from human Liver tissue interstitial fluid (TIF) are blocked, restricting their positive charge, at acidic pH, to the presence of histidine and arginine residues. After strong cation exchange chromatography, multiply-charged peptides (#R+#H > 1) are retained in the column and separated with high selectivity from singly (#R+#H = 1) and neutral peptides (#R +#H = 0) which are collected together in the flow-through.

[Direct cryothermal ablation eliminates conduction of the slow pathway without inducing ectopic rhythms].

Radiofrequency catheter ablation of atrioventricular nodal reentrant tachycardia is based on the elimination of conduction of slow or fast intranodal pathway. To avoid potential atrioventricular (AV) block, a new technology has been developed, cryothermal ablation. We report a case of AV nodal reentrant tachycardia in whom direct cryoablation, without previous ice mapping, was successfully performed.

Influence of infarct-related artery patency on the indexes of parasympathetic activity and prevalence of late potentials in survivors of acute myocardial infarction.

Objectives: The purpose of this study was to determine whether infarct-related coronary artery patency influences myocardial electrical stability as measured by the prevalence of late potentials or heart rate variability.

Background: Several studies have suggested that loss of vagal activity is associated with an increased incidence of arrhythmic death after myocardial infarction.

Methods: A short-duration, high resolution electrocardiogram (ECG) was performed before hospital discharge in 175 patients with a first myocardial infarction.
