background: atrial fibrillation (af) is the most common cardiac arrhythmia and an independent risk factor for stroke among the elderly. a role for inflammation in the atrial remodeling as well as development and recurrence of af is known. objective: to compare il-17a between patients with different types of af and healthy individuals. methods: il-17a was measured in sera of 112 patients and 107...
Atrial fibrillation (AF) is the most common sustained arrhythmia in patients with chronic kidney disease (CKD). In this study, we examined the association between inflammation and AF in 3,762 adults with CKD, enrolled in the Chronic Renal Insufficiency Cohort (CRIC) study. AF was determined at baseline by self-report and electrocardiogram (ECG). Plasma concentrations of interleukin(IL)-1, IL-1 ...
AIMS Although inflammation appears to play a pivotal role in the pathophysiology of atrial fibrillation (AF), the source of inflammation is unknown. We hypothesized that multilevel measurement of several inflammatory proteins in AF patients would help assess the extent and the source of inflammation. METHODS AND RESULTS Thirty-nine patients with paroxysmal AF, 33 with persistent AF, and 9 con...
BACKGROUND Atrial fibrillation (AF) is the most common clinically significant arrhythmia in adults and a major risk factor for ischemic stroke. Nonetheless, previous research suggests that many individuals diagnosed with AF lack awareness about their diagnosis and inadequate health literacy may be an important contributing factor to this finding. METHODS AND RESULTS We examined the associatio...
Intake of specially processed cereal (SPC) stimulates endogenous antisecretory factor (AF) activity, and SPC intake has proven to be beneficial for a number of clinical conditions. The aim of the present study was to investigate the dosage relationship between SPC intake and plasma AF activity and to further correlate achieved AF levels to a biological effect. SPC was fed to rats in concentrati...
This paper describes an antenna design approach for achieving super directivity in AESA (Active Electronic Scanned Array) radar using unconventional 3D phased array (PA) concept based on directional Yagi–Uda elements. The proposed scheme is shown to have a wider scanning feature, with higher comparison the same geometry dipole without increasing element number. antenna’s microwave includes anti...
The local evanescent array coupled (LEAC) chip-scale sensor is demonstrated for rapid detection of benzene, toluene and xylenes (BTX) in water at sub-ppm concentrations with minimal sample preparation. BTX analytes are found to concentrate into the chip’s Teflon AF upper cladding sensing region, causing an increase in refractive index, which modulates evanescent coupling into the chip’s integra...
Case report A 54-year-old man with mild to moderate hemophilia A, obstructive sleep apnea on continuous positive airway pressure, and paroxysmal AF was referred for AF catheter ablation. Four years prior, he was evaluated for palpitations and dyspnea. AF was confirmed on ambulatory monitoring. His CHA2DS2-VASc score was 0. He was trialed on a series of antiarrhythmic medications including fleca...
The estrogen receptor (ER), like other members of the nuclear receptor superfamily, possesses two separate transcriptional activation functions, AF-1 and AF-2. Although a variety of coactivators and corepressors of AF-2 have been identified, less is known of the mechanism of action of AF-1. We have used the yeast two-hybrid system to isolate a cDNA coding for a protein that binds specifically t...
BACKGROUND The risk of stroke imposed by atrial fibrillation (AF) is significantly greater in women than men; however, the mechanism remains elusive. We hypothesized that left atrial (LA) remodeling and poor contractile function of LA appendage (LAA) would be more predominant in women than men among AF patients. METHODS AND RESULTS A total of 579 AF patients (216 women vs age-, AF type-, and ...
