The active fraction (AF) from lxora coccinea flowers prevented the decrease in haemoglobin levels and leucocyte counts of Dalton's lymphoma tumour bearing mice, treated with cyclophosphamide (CYP). It also significantly increased the life span of tumour bearing mice, treated with cyclophosphamide. Serum glutamate pyruvate transaminase (SGPT) and serum alkaline phosphatase (SAKP) levels of tumou...
PURPOSE To elucidate the anatomy of the trabecular meshwork (TM) and its connection to ciliary muscle (CM) tendons with two photon excitation microscopic (TPEM) imaging. METHODS The human aqueous outflow pathway was imaged in an unfixed and nonembeded state by using an inverted TPEM. Laser (Ti:Sapphire) was tuned at 850 nm for emission. Backscatter signals of second harmonic generation (SHG) ...
Background—To distinguish prolonged episodes of atrial fibrillation (AF) that require cardioversion from self-terminating episodes that do not, an atrial implantable cardioverter-defibrillator (ICD) must be able to detect AF continuously for extended periods. The ICD should discriminate between atrial tachycardia/flutter (AT), which may be terminated by antitachycardia pacing, and AF, which req...

BACKGROUND Risk factors for atrial fibrillation (AF) recurrence in patients who have undergone AF catheter ablation have not been fully clarified. The objective of this study was to assess whether the left atrium (LA) and LA appendage (LAA) volumes, and cardio-metabolic markers such as polyunsaturated fatty acids (PUFAs) levels were associated with AF recurrence. METHODS Seventy-seven consecu...
Atrial fibrillation (AF) is the most common arrhythmia worldwide and a potent independent risk factor for stroke. This study aimed to determine the prevalence of AF in a population-based sample of adults in a rural region of Korea. Between January 2005 and December 2009, 4,067 individuals (60.2 ± 11.2 yr old, M: F = 1,582:2,485) over 21 who were residents of the county of Yangpyeong, Korea, par...
OBJECTIVES Surgical ablation for atrial fibrillation (AF) is an established therapy for the treatment of concomitant AF in cardiac surgery patients. We aim to present our prospective experience with 99 continuously monitored patients and investigate whether enhanced monitoring can identify patterns and factors influencing AF recurrence after surgical AF ablation. METHODS Ninety-nine patients ...
BACKGROUND In patients with heart failure and preserved ejection fraction (HFpEF), atrial fibrillation (AF) may predate, concur with, or develop after HFpEF diagnosis. We sought to define the temporal relationship between AF and HFpEF, to identify factors associated with AF, and to determine the prognostic impact of prevalent and incident AF in HFpEF. METHOD AND RESULTS From 1983 to 2010, 939...
The AF-6 protein is a multidomain protein that contains two potential Ras-binding domains within its N terminus. Because of this feature, AF-6 has been isolated in both two-hybrid and biochemical approaches and is postulated to be a potential Ras-effector protein. Herein, we show that it is specifically the first Ras-binding domain of AF-6 that mediates this interaction and that the Ras-related...
BACKGROUND Several studies have shown associations between blood lipid levels and the risk of atrial fibrillation (AF). To test the potential effect of blood lipids with AF risk, we assessed whether previously developed lipid gene scores, used as instrumental variables, are associated with the incidence of AF in 7 large cohorts. METHODS We analyzed 64,901 individuals of European ancestry with...
