b ackground: in this study the concentration of lysozyme in blood plasma of  microtus agrestis, clethrinomys glareolus , apodemus sylvaticus, bk rats and outbred white mice before and after infection with culture forms of trypanosoma microti, t, evotomys, t. grosi, t. lewisi and t. musculi respectively was measured. m ethods: blood samples of rodents, microtus agrestis, clethrionomys glareolus,...

Artificial grafts are promising alternatives to nerve grafts for peripheral nerve repair because they obviate the complications and disadvantages associated with autografting such as donor site morbidity and limited tissue availability. We have synthesized poly(2-hydroxyethyl methacrylate-co-methyl methacrylate) (PHEMA-MMA) porous tubes and studied their efficacy in vivo. Specifically, we studi...

BACKGROUND Current methods of female surgical sterilisation require incisional surgery, general anaesthesia and a prolonged recovery time. We studied the safety and effectiveness of Essure pbc, a minimally invasive, transcervically placed micro-insert that occludes the Fallopian tubes, resulting in permanent female contraception. Device under study: The Essure pbc implant is a dynamically expan...

Two-phase flow regimes are affected by conduit position, alignment, geometry, flow direction, physical characteristics, and flow rate of each phase as well as the heat flux toward the boundaries. Due to the importance of two-phase flow, numerous regimes have been identified. The first step in studying micro-bubble formation inside a venturi tube is to recognize the type of flow regimes. In this...

Abstract Compared with low-permeability oil reservoirs, tight reservoirs have more nanopores, complex pore structure, and obvious nonlinear seepage characteristics. Under the macro-scale channel flow, influence of micro-forces is often ignored, but micro-nano-scale become main factors affecting flow. The flow different from requires force between fluid micro-nano tubes. article conducts thresho...
