INTRODUCTION To investigate the oxidative stress and its association with antioxidants in patients on hemodialysis, we evaluated the levels of albumin, C-reactive protein (CRP), ferritin, vitamin E, glutathione, and total antioxidant capacity in these patients. MATERIALS AND METHODS In a cross-sectional study, we enrolled 25 patients on maintenance hemodialysis and measured the inflammatory a...

We introduce transverse diffusion of laminar flow profiles (TDLFP), the first generic method for mixing two or more reactants inside capillaries. Conceptually, solutions of reactants are injected inside the capillary by pressure as a series of consecutive plugs. Due to the laminar nature of flow inside the capillary, the nondiffused plugs have parabolic profiles with predominantly longitudinal ...

The behavior of the single-species reaction process A + A → O is examined near an impenetrable boundary, representing the flask containing the reactants. Two types of dynamics are considered for the reactants: diffusive and ballistic propagation. It is shown that the effect of the boundary is quite different in both cases: diffusion-reaction leads to a density excess, whereas ballistic annihila...

Kramers' theory frames chemical reaction rates in solution as reactants overcoming a barrier in the presence of friction and noise. For weak coupling to the solution, the reaction rate is limited by the rate at which the solution can restore equilibrium after a subset of reactants have surmounted the barrier to become products. For strong coupling, there are always sufficiently energetic reacta...

Based on a theoretical model where the nuclear spins remain unchanged during collision, we provide an analytical and general expression for spin state-to-state distribution of ultracold chemical reaction in magnetic field, given rotational transitions molecules. It simply requires knowledge field-dependent eigenfunctions molecular reactants products reaction. The final drastically changes with ...

In order to control flows and temperature distribution within plasma reactors experimentally requires significant research development costs. the computational fluid dynamics (CFD) can be used as a powerful tool investigate flow pattern heat transfer inside allowing us construct best designs with minimal cost. this work profile gas in thermal reactor for carbon nanotubes synthesis is studied by...

Molecule based signal amplifications relying on an autocatalytic process may represent ideal strategy for the development of ultrasensitive analytical or bioanalytical assays, main reason being exponential nature amplification. However, to take full advantage such amplification rates, high stability starting co-reactants is required in order avoid any undesirable background Here, basis a simple...
