Abstract:
SummaryThrombin generation is decreased and delayed in plasma from newborns and children compared to adults. We hypothesized that lower doses of heparinoid anticoagulants are required to give similar thrombin generation in newborn (umbilical cord) and child plasmas compared to that of adults. Thrombin generation was performed in either the absence or presence of unfractionated heparin (UFH), low molecular weight heparin (LMWH) or a covalent antithrombin-heparin complex (ATH). After contact activation and recalcification of each plasma, thrombin activity was measured by periodic sub-sampling in

Chemically reactive plasma discharges are widely used to process materials. A plasma is a primarily electrically neutral collection of free charged particles moving in random directions. The simplest plasma consists of electrons and one kind of positive ions. This article deals primarily with plasma discharges, which are plasmas having the following features:(1) They are driven electrically.(2) Charged-particle collisions with neutral-gas molecules are important.(3) There are boundaries at which surface losses are important.(4) Ionization of neutrals sustains the plasma in the steady state.One

After 0 to 90 minutes (37°C) 50 µl 2.5 M arginine, pH 8.6, was added. After 20 minutes, thrombin was chromogenically quantified. In normal recalcified plasma, the generated thrombin activity is about 0.1-0.2 IU/ml (37°C) when fibrin generation starts. Pooling of normal plasmas increases the generated thrombin activity about 3-fold. Plasmas of patients on heparin or coumarin generate about 10-fold less thrombin activity

Abstract Hemophilia is a hereditary bleeding disorder caused by intrinsic coagulation pathway deficiencies of Factor VIII (hemophilia A) or Factor IX (hemophilia B).

In hemophilia patients the extrinsic pathway remains intact and thus augmentation of this pathway may circumvent the clotting deficiency in hemophilia.

Abstract Abstract 1143 Background: Microparticles (MP) exhibit procoagulant activity by exposure of tissue factor (TF) and consecutive factor (F) × activation via binding to activated FVII (FVIIa). We have shown that TF-negative MP derived from endothelial cells (EMP) after exposure to cisplatin induce thrombin generation in vitro in a TF-independent manner (Lechner et al., J. Thromb. Haemost. 2007). The procoagulant properties of TF-negative MP are not well characterized. We therefore aimed to investigate the mechanisms of coagulation activation by TF-negative EMP (obtained from human pulmona

Abstract:
Saudi women have recently started using oral contraceptives (OCs), which has led to risk of venous thromboembolism (VTE). The risk varies with the type of OC generations used, and with OC use the risk for VTE increases by 2- to 6-fold. This study evaluated the effect of OC types in relation to ABO blood group on the risk of VTE among Saudi women. Thrombin generation (TG) was measured in the plasma of the women in the presence and absence of platelet rich plasma, platelet poor plasma and thrombomodulin or activated protein C. OC usage increased TG parameters ETP and Peak height by 9.81% and 16.

Abstract:
The molecular laser-induced plasma (LIP) produced during the ablation of silver sulfide (Ag2S) was used as a medium for high-order harmonic generation in the extreme ultraviolet range. The role of LIP formation, the plasma components, and the geometry of plasma in the harmonic conversion efficiency was analyzed. We also analyzed the influence of the driving pulses (chirp, single-color pump, two-color pump, and delay between heating and converting pulses) on the harmonic yield in Ag2S LIP. The application of molecular plasma was compared with the application of atomic plasma, which comprised si

Abstract:
Based on the turbidimetric curve of formation and dissolution of a blood plasma clot initiated by the activated partial thromboplastin time reagent, a method for determining the coagulation component of thrombin activity and fibrinolytic activity of plasmin is proposed. The activity of thrombin was calculated by the value of the lag period, and plasmin by its amidase activity at the moment of complete dissolution of the clot. At the end of the lag period, about 0.45% of the available prothrombin was activated, and at the moment of complete dissolution of the clot 1.05% of the available plasmin

Abstract:
SummaryThe effects of unfractionated heparin (UH) and recombinant hirudin (rH) on prothrombin activation, free thrombin generation, and platelet aggregation induced by endogenously generated thrombin after intrinsic activation of platelet rich plasma were compared. Free thrombin generation and platelet aggregation were assessed simultaneously by delaying fibrinogen polymerisation with GPRP.UH more effectively inhibited prothrombin activation and free thrombin generation than rH. Increasing concentrations of rH had hardly any effect on the peak amount of free thrombin, while in the presence of

Abstract:
The concept of dense and hot plasmas can be used to build up powerful and brilliant radiation sources in the soft X-ray and extreme ultraviolet spectral range. Such sources are used for nanoscale imaging and structuring applications, such as EUV lithography in the semiconductor industry. An understanding of light-generating atomic processes and radiation transport within the plasma is mandatory for optimization. The basic principles and technical concepts using either a pulsed laser or a gas discharge for plasma generation are presented, and critical aspects in the ionization dynamics are outl

Abstract:
We propose a low-density discharge plasma model that takes into account the impact of oxygen admixture in typical conditions of complex (dusty) plasmas. Numerical simulations based on this model show that the concentration of negative ions turns out to be very high, and they play an important role in the overall kinetics in this particular range of plasma conditions. The ambipolar diffusion electric field drags these negative ions into the center of the plasma. The density of negative ions is high enough to push the negatively charged dust component out of the center, both by weakening the rad

Abstract:
The construction of short pulse (<200 fs) tunable X-ray laser sources based on the X-ray free electron laser (XFEL) concept will be a watershed for plasma-based and warm dense matter research. These new fourth generation light sources will have extremely high fields and short wavelengths (∼0.1 nm) with peak spectral brightnesses 1010 greater than third generation sources. Further, the high intensity upgrade of the GSI accelerator facilities will lead to specific energy depositions up to 200 kJ/g and temperatures between 1 and 10 eV at almost solid-state densities, enabling interesting exper

Abstract:
Neutral beam injection is supposed to be the main source of high-energy particles, driving non-inductive current and generating primary neutrons in fusion neutron sources design based on tokamaks. Numerical simulation of high-energy particles’ thermalization in plasma and fusion neutron emission is calculated by novel dedicated software (NESTOR code). The neutral beam is reproduced statistically by up to 109 injected particles. The beam efficiency and contribution to primary neutron generation is shown to be dependent on the injection energy, input current, and plasma temperature profile. A be
