BACKGROUND Myeloproliferative neoplasms (MPN) encounter thromboses due to multiple known risk factors. Heparin-induced thrombocytopenia (HIT) is a thrombotic syndrome mediated by anti-platelet factor 4 (PF4)/heparin antibodies with undetermined significance for thrombosis in MPN. We hypothesized that anti-PF4/heparin Ab might occur in MPN and promote thrombosis. METHODS Anti-PF4/heparin antib...

Photovoltaic (PV) system adoption in Germany is mainly driven by a feed-in tariff that guarantees a financial return on investment. To promote adoption in the future absence of this tariff, we explored further motives of homeowners relevant to PV system purchase intention. A sample of 200 homeowners who did not own a PV system participated in an online-survey. Only few homeowners actually plann...

The aetiology of post-polio syndrome may involve persistence of poliovirus (PV) in the CNS. PV persists in the CNS of infected paralysed mice for over a year after the acute phase of paralytic poliomyelitis. However, infectious PV particles cannot be recovered from homogenates of CNS from paralysed mice after the acute phase of disease, indicating that PV replication is restricted. To identify ...

HYPOTHESIS The depth of portal vein (PV) wall invasion is a prognostic factor for survival after curative pancreatic resection for pancreatic ductal adenocarcinoma. DESIGN Retrospective clinical study. SETTING Department of digestive surgery and transplantation. PATIENTS From January 1, 1990, through December 31, 2002, 121 patients underwent a curative pancreatic resection for ductal aden...

OBJECTIVES We investigated the hypothesis that re-entrant pulmonary vein (PV) tachycardias may serve as a mechanism for initiating and sustaining paroxysmal atrial fibrillation (PAF). BACKGROUND The mechanisms of rapid repetitive discharges from the PV initiating PAF remain incompletely understood. Pulmonary vein myocardial sleeves appear to provide a favorable substrate for re-entry formatio...

AIMS Prion diseases are generally characterized by pronounced neuronal loss. In particular, a subpopulation of inhibitory neurones, characterized by the expression of the calcium-binding protein parvalbumin (PV), is selectively destroyed early in the course of human and experimental prion diseases. By contrast, nerve cells expressing calbindin D28 k (CB), another calcium-binding protein, as wel...

BACKGROUND Despite extensive proximal ablation, all potentials frequently cannot be eliminated from the left pulmonary veins (PV). Methods and Results- PV electrograms were analyzed during sinus rhythm, coronary sinus, and left atrial appendage (LAA) pacing, and PV and LAA angiography performed. During pacing, an initial low-amplitude slow potential was recorded on the anterior aspect of the le...

Two-dimensional unsteady incompressible flows in which the potential vorticity (PV) plays a key role are examined in this study, through the development of the evolution equation for the PV gradient. For the case where the PV is conserved, precise statements concerning topologyconservation are presented. While establishing some intuitively well-known results (the numbers of eddies and saddles i...

Make your home solar is going to be reality within few years. Rooftop PV has been developed by Germany, Spain and Italy with the encouragement Feedin -Tariff system for early attaining towards grid parity. The rates of solar PV has been drastically reduced in recent years and approaching towards the grid parity. There has been increasing trend of grid connected residential rooftop PV worldwide ...

Though many options exist, the application of integrated PV systems in mass produced consumer products is still unusual and rare [1]. Therefore, to date, design and manufacturing aspects of product-integrated PV systems have been explored only to a very limited extent. The requirements for the design of consumer products are evidently different from those for PV systems. Moreover, product desig...
