BACKGROUND Endo-epicardial dissociation (EED) of electric activations resulting in transmural conduction of fibrillation waves (breakthroughs) has been postulated to contribute to the complexity of the substrate of atrial fibrillation (AF). The aim of this study was to elucidate the correlation between EED and incidence of breakthrough and to test the plausibility of transmural conduction versu...

OBJECTIVE Rapid analgesic onset opioids, particularly fentanyl buccal tablet, is preferable for managing breakthrough pain. The efficacy and safety of fentanyl buccal tablet and its association with around-the-clock opioids needs to be explored with an option of dose adjustments, more closely reflecting administration in clinical practice. The aim of the study was to assess the safety and effic...

PURPOSE We constructed a risk prediction instrument stratifying patients with primary vesicoureteral reflux into groups according to their 2-year probability of breakthrough urinary tract infection. MATERIALS AND METHODS Demographic and clinical information was retrospectively collected in children diagnosed with primary vesicoureteral reflux and followed for 2 years. Bivariate and binary log...

Packed column and mathematical modeling studies were conducted to explore the influence of water saturation, pore-water ionic strength, and grain size on the transport of latex microspheres (1.1 microm) in porous media. Experiments were carried out under chemically unfavorable conditions for colloid attachment to both solid-water interfaces (SWI) and air-water interfaces (AWI) using negatively ...

How can companies simultaneously excel at today’s business while building tomorrow’s? It is a delicate organizational task. But new principles based on five years of research show that established organizations can build new futures when they design breakthrough new business units so that they can forget, borrow, and learn. Creating the future requires both breakthrough ideas and breakthrough e...

in many reservoirs, after water flooding, a large volume of oil is still left behind. hot water injection is the most basic type of thermal recovery which increase recovery by improved sweep efficiency and thermal expansion of crude.in the present work, the effects of injection rate and the temperature of the injected water were surveyed by using core flooding apparatus. water flooding was perf...

BACKGROUND Viral suppression and viral breakthrough impact the humoral immune response to HIV infection. We evaluated the impact of viral suppression and viral breakthrough on results obtained with two cross-sectional HIV incidence assays. METHODS All samples were collected from adults in the US who were HIV infected for >2 years. Samples were tested with the BED capture enzyme immunoassay (B...

OBJECTIVE Varicella breakthrough, the occurrence of varicella disease >42 days after vaccination, is indicative of vaccination failure. A sevenfold increased risk of breakthrough among vaccinated children with asthma was observed in a 1996 varicella outbreak in a child care center. More recent outbreak investigations have also identified age at vaccination as a potential risk factor for breakth...

“Space drives,” “Warp drives,” and “Wormholes:” these concepts may sound like science fiction, but they are being written about in reputable journals. To assess the implications of these emerging prospects for future spaceflight, NASA supported the Breakthrough Propulsion Physics Project from 1996 through 2002. This project has three grand challenges: (1) Discover propulsion that eliminates the...
