The electrophysiologic properties of diphenylhydantoin (DPH) (5-10 mg/kg) intravenously was studied in 14 subjects using His bundle recordings and correlated with blood levels. Conduction through the A-V conducting system (AVCS) was studied at various paced atrial rates and refractory periods determined using programmed atrial premature depolarization within 10 min of drug administration. In 11...

this presentation features, modalities: plain radiographs, ct, mri, and ultrasound; arthroplasty; hardware loosening; suture anchor migration; avn, collapse, arthritis; rotator cuff repair; labral repair.

Handwritten signature verification is a crucial yet challenging problem. While previous studies have made great progress in this problem, they learn features passively from given existing data. In paper, we propose novel adversarial variation network (AVN) model for handwritten which mines effective by actively varying data and generating new Powered proposed consistency mechanism, the AVN cont...

OBJECTIVE Screening for hip dysplasia is controversial. A previous randomized controlled trial revealed that adding universal or selective ultrasound to routine clinical examination gave a nonsignificant reduction in rates of late presenting cases, but with higher treatment rates. This study assesses differences in outcome at skeletal maturity for the 3 newborn screening strategies in terms of ...

A high intake of whole grain foods is associated with reduced risk of colon cancer, but the mechanism underlying this protection has yet to be elucidated. Chronic inflammation and associated cyclooxygenase-2 (COX-2) expression in the colon epithelium are causally related to epithelial carcinogenesis, proliferation, and tumor growth. We examined the effect of avenanthramides (Avns), unique polyp...

The atrioventricular node (AVN) is the relay station for electrical impulses passing from the atria to the ventricles. The arterial resources of the AVN are functionally relevant and may be interfered by various surgical procedures which deal with the cardiac valves. Our study aim to bring detailed evidences on the arterial supply of the AVN. We dissected and microdissected 50 human adult heart...

The progressive prolongation of atrioventricular node (AVN) conduction time to a new steady-state value caused by sudden and maintained increases in atrial rate is the most common form of AV nodal accommodation. This study was undertaken to 1) characterize AV nodal accommodation in isolated perfused guinea pig hearts, 2) investigate the influence of potential modulators of this phenomenon such ...

The sphingosine-1-phosphate (S1P) receptor modulator, fingolimod (FTY720), has been used for the treatment of patients with relapsing forms of multiple sclerosis, but atrioventricular (AV) conduction block have been reported in some patients after the first dose. The underlying mechanism of this AV node conduction blockade is still not well-understood. In this study, we hypothesize that express...

We report a case of open talar fracture-dislocation (Gustilo-Anderson type IIIA) associated with posterior tibial artery injury. The limb was aligned and splinted in the emergency department. In operating theater, ligated, neck fracture reduced, it fixed two Kirschner wires (K-wires). After K-wire removal, patient underwent rehabilitation to regain function resumed activities daily living (ADL)...

BACKGROUND Matrix metalloproteinases (MMPs) have a pivotal role in the destruction of cartilage in rheumatoid arthritis (RA), which is mediated by the fibroblast-like synoviocytes (FLS). OBJECTIVE To examine the in vitro invasiveness of synoviocytes obtained from inflamed joints of patients with arthritis in relation to the expression of MMP 1-14, 17, 19, cathepsin-K, the tissue inhibitors of...
