nowadays nanotechnology as a new direction of science allows us to develop therapeutic methods of the endogenous intoxication syndrome and to create a new class of biocompatible sorbents. in ukraine first preparations of medical nanotechnology were produced and patented in 1998. these are ikbb (intracorporeal biocorrector), magnet-controlled sorbent (mcs-b), and micromage-b. the preparations ar...

OBJECTIVES To determine the effects of pump priming fluid choice on platelets, fluid balance, and clinical outcomes. DESIGN Meta-analysis of controlled clinical trials. Primary endpoints were platelet counts, colloid oncotic pressure, on-bypass fluid balance, postoperative weight gain, and colloid usage. SETTING Cardiac surgery with cardiopulmonary bypass. PATIENTS Adult and pediatric pat...

Using Gibbs ensemble Monte Carlo simulations and density functional theory we investigate the fluid-fluid demixing transition in inhomogeneous colloid-polymer mixtures confined between two parallel plates with separation distances between one and ten colloid diameters covering the complete range from quasi-two-dimensional to bulklike behavior. We use the Asakura-Oosawa-Vrij model in which collo...

The biodistribution of a nanometer-sized colloid was tested in three groups of rats, one with a turpentine-induced abscess and one with a histamine-induced oedema in the musculature of a hind leg. The third group served as a control. A 99Tcm-labelled colloid with a mean particle size of 30 nm was administered to each group intravenously. The biodistribution of the tracer, studied 1 h after inje...

Transport of colloids with transient wetting fronts represents an important mechanism of contaminant migration in the vadose zone. The work presented here used steady-state saturated and transient unsaturated flow columns to evaluate the transport of a fluorescent latex microsphere (980 nm in diameter) with capillary wetting fronts of different solution surface tensions and ionic strengths. The...

Thyroglobulin (Tg), the thyroid hormone precursor, is synthesized by thyrocytes and secreted into the colloid. Hormone release requires uptake of Tg by thyrocytes and degradation in lysosomes. This process must be precisely regulated. Tg uptake occurs mainly by micropinocytosis, which can result from both fluid-phase pinocytosis and receptor-mediated endocytosis. Because Tg is highly concentrat...

Submitted for the MAR10 Meeting of The American Physical Society Hydrodynamic Interaction of Colloid Suspension in Ribbon Channels1 BINHUA LIN, SERGEY NOVIKOV, STUART A. RICE, University of Chicago — We report the results of an experimental study of hydrodynamic interaction in colloid suspensions that are intermediate between quasi-one-dimensional (q1D) and quasi-two-dimensional (q2D) systems. ...

BACKGROUND: Literature data on the effect of methionine functional activity and, especially, morphological changes in thyroid gland are sporadic. This may be due to a number reasons, such as: different ages experimental animals; dosage methionine; seasonality and duration experiments.
 AIM: To investigate rats after administration.
 MATERIAL AND METHODS: The experiments were performed...
