The plasma membrane of murine erythro-leukemia (MEL) cells contains a 140-kD protein that binds specifically to fibronectin. A 125I-labeled 140-kD protein from surface-labeled uninduced MEL cells was specifically bound by an affinity matrix that contained the 115-kD cell binding fragment of fibronectin, and specifically eluted by a synthetic peptide that has cell attachment-promoting activity. ...

purpose: to evaluate the incidence of the oculo-cardiac reflex (ocr) and its associated risk factors during strabismus surgeries performed at a tertiary referral center between 1390 and 1392. methods: over a 2-year period, all strabismus surgery candidates were enrolled in the study after obtaining consent from the patients or their parents. vital signs were recorded before the initiation of th...

Ms. A is a 33-year-old woman with a history of depression and polysubstance use disorder who presented to our hospital after transfer from another facility’s emergency department after an intentional flecainide overdose. Her spouse heard a “thud” at approximately 5 AM on the day of admission. He found her unconscious after she had ingested 12 tablets of 150-mg flecainide originally prescribed t...

Atrial fibrillation (AF) is the most common arrhythmia and associated with increased morbidity mortality. The mechanisms underlying transition from paroxysmal to persistent AF are still a matter of debate. Recent studies indicate potential role for metabolic remodelling in stabilization process levels specific substrate, succinate, have been found blood plasma patients. While succinate known in...

In their paper published in the February issue of JAFIB, Dr. Barrios and colleagues further examine the association between atrial fibrillation, classical coronary risk factors, proven cardiovascular preventive therapies and end-organ damage in 2024 patients with documented hypertension and coronary heart disease. Patients were stratified as having or not having atrial fibrillation according to...

An interesting problem in musicology is to classify songs according to rhythms. A rhythm is represented by a sequence of “Quick” (Q) and “Slow” (S) symbols, which correspond to the (relative) duration of notes, such that S = 2Q. Recently, Christodoulakis et al. [3] presented an efficient algorithm that can be used to classify musical texts according to rhythms. In this paper, we implement the a...

A fundamental problem in music is to classify songs according to their rhythm. A rhythm is represented by a sequence of “Quick” (Q) and “Slow” (S) symbols, which correspond to the (relative) duration of notes, such that S = QQ. In this paper we present a linear algorithm for locating the maximum-length substring of a music text t that can be covered by a given rhythm r. An efficient algorithm t...

Rev Esp Cardiol. 2005;58(1):91-2 91 Ventricular noncompaction is a recognized variety of myocardial disease involving systolic and diastolic ventricular dysfunction. We present a 3-D echocardiographic reconstruction in a 52-year-old woman with a 2-year history of palpitations and heart failure that improved with initiation of pharmacologic therapy. The electrocardiogram showed sinus rhythm at 7...

Cardiac rhythm problems are frequently seen in the geriatric population, and they can experience trauma after syncope. A 78-year-old female was examined for thoracic trauma after falling. With a history of beta-blocker use, arterial blood pressure measured 60/30 mmHg and pulse rate was 30 bpm. Electrocardiogram showed a Mobitz type-II second-degree atrioventricular block. There was no response ...
