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...

The efficiency of the ocean’s biological carbon pump (BCPeff – here the product of particle export and transfer efficiencies) plays a key role in the air–sea partitioning of CO2. Despite its importance in the global carbon cycle, the biological processes that control BCPeff are poorly known. We investigate the potential role that zooplankton play in the biological carbon pump using both in situ...

Objective: Soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. Organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. So, this research has been done for achieving this purpose. Methods: This...

We present a new impulse-based method, called the Tethered Particle System (TPS), for the dynamic simulation of deformable biological structures. The TPS is unusual in that it may capture a gradual process of deformation using only instantaneous impulses that occur in response to particle collisions. This paper describes the method and its application to synaptic vesicle clusters and deformable...

The chitosan nanoparticles used widely as a drug delivery systems recently. In the present study the Echis carinataus snake venom loaded chitosan nanoparticles were prepared based on ionic gelation of tripolyphosphate and chitosan. The nanoparticles physicochemical characteristics, stability and biological activity of encapsulated venom were studied. The particles were spherical in shape and th...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1159. 65 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-8991-5. Single-particle tracking is a technique that allows for quantitative analysis of the localization and movement of particles. In this ...

A superposition rule for light scattering by composite particles is presented that expresses the scattering amplitude of a composite particle as a superposition of that of the host particle and those of the shadowed inclusions. The superposition rule is derived for a soft composite particle but also provides insight into light scattering by a general composite scatterer. Favorable comparison wi...

In the previous review, the physical aspect of heavy particles, with a focus on the carbon beam was introduced. Particle beam therapy has many potential advantages for cancer treatment without increasing severe side effects in normal tissue, these kinds of radiation have different biologic characteristics and have advantages over using conventional photon beam radiation during treatment. The re...
