A 65-year-old woman underwent an electrophysiologic procedure because of a 20-year history of paroxysmal supraventricular tachycardia. The baseline sinus cycle length was 800 msec, with an atrial-His interval (AH) of 100 msec and a His-ventricular interval (HV) of 40 msec. There was evidence of dual AV nodal pathways, but no inducible tachycardia. During infusion of isoproterenol, the sinus cyc...

Students are experiencing difficulty with online learning because it requires infrastructure, such as internet access that needs to be purchased. This study examined whether lectures increase or decrease family/student expenses on education using a qualitative approach. Data expenditures were collected by interviewing 736 students at State Islamic University (UIN) Antasari, Indonesia before the...

Background: To evaluate the medium and late term outcomes of coronary artery bypass grafting with pull-through coronary endarterectomy using a saphenous vein patch for bypass distal anastomosis site. Methods: Retrospective review of all coronary artery bypass graft (CABG) procedures performed from January 1, 2000 through June 30, 2013 with and without concomitant coronary endarterectomy (CE), w...

Currently 33% of the Polish adult population smoke tobacco (42% males and 25% females), which is a serious issue, particularly in the context of cardiovascular diseases. A study of the extent of smoking among patients with arterial hypertension (AH) served as the basis for the present article. The studied group comprised 100 patients hospitalised due to AH, 46 males and 54 females. A survey, ai...

Background: Cystic echinococcosis (CE), as a chronic parasitic disease, is a major health problem in many countries. The performance of the currently available serodiagnostic tests for the diagnosis of CE is unsatisfactory. Objective: The current study aimed at sub-cloning a gene, encoding the B8/1 subunit of antigen B (AgB) from Echinococcus granulosus, using gene optimization for the immunodi...

in the present study common kilka from guilan province coastal area (port of anzali) and fish meal produced from it, have been examined to investigate the type and amount of polyaromatic hydrocarbons (pahs). bio monitoring is very important because these pollutants are carcinogenic and mutagenic compounds, if they enter human food chain. sampling process was completed in anzali fishing port. fo...

The syndrome of enhanced atrioventricular nodal (AVN) conduction has been defined arbitrarily by: AH interval during normal sinus rhythm (AH-NSR) less than or equal to 60 msec; shortest right atrial pacing cycle length (PCL) maintaining 1:1 AVN conduction (shortest PCL 1:1) less than or equal to 300 msec; and at the shortest PCL 1:1, an increase in the AH interval from AH-NSR (delta AH) less th...

PURPOSE To compare the short- and long-term sealing ability of root canal fillings consisting of AH-26 and laterally compacted gutta-percha in combination with a self-etching dentin bonding system and the Epiphany-Resilon system. MATERIALS AND METHODS Ninety-eight single-rooted human teeth were used in this study. The root canals were prepared using the step-back technique. Sodium hypochlorit...

In case 1, a 71-year-old man with a history of coronary artery disease presented with recurrent paroxysmal supraventricular tachycardia (SVT) despite treatment with -blockers. During electrophysiology study, the baseline sinus cycle length was 895 ms, atrial-His (AH) interval was 120 ms, and His-ventricular interval was 60 ms. A narrow complex SVT with tachycardia cycle length of 480 ms was ini...
