Background: An imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. The purpose of this study was to determine the transcranial doppler sonography (TDS) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. Methods: This study was carried out on 46 pa...

Annually, web search engine providers spend more and more money on documents ranking in search engines result pages (SERP). Click models provide advantageous information for ranking documents in SERPs through modeling interactions among users and search engines. Here, three modules are employed to create a hybrid click model; the first module is a PGM-based click model, the second module in a d...

BACKGROUND Echocardiographic evaluations of the longitudinal axis of the left ventricular (LV) function have been used in the diagnosis and assessment of heart failure with normal ejection fraction (HFNEF). The evaluation of the global and segmental peak systolic longitudinal strains (PSLSs) by two-dimensional speckle tracking echocardiography (STE) may correlate with conventional echocardiogra...

BACKGROUND Most studies on cardiac function in athletes describe overall heart function in predominately male participants. We aimed to compare segmental, regional and overall myocardial function and synchrony in female endurance athletes (ATH) and in age-matched sedentary females (CON). METHODS In 46 ATH and 48 CON, echocardiography was used to measure peak longitudinal systolic strain and m...

THE PROLAPSED MITRAL VALVE, or clickmurmur syndrome, continues to evoke interest, concern and controversy. Although the midsystolic click and late systolic murmur were well described in the late 19th century,1 it was not until 1961 that Reid2 suggested the mitral valve as the cause of the click and mitral insufficiency as the cause of the murmur. This was confirmed by angiocardiography and phon...

Sir, One should differentiate angiographic prolapse from midsystolic click, the auscultatory hallmark of the mitral valve prolapse-click syndrome. In my articles quoted by the authors, I have refuted the causal association between coronary artery disease and the midsystolic click rather than between coronary artery disease and angiographic mitral valve prolapse. In coronary artery disease, angi...
