Effect of gradual computerized angioplasty on outcomes of patients undergoing coronary stenting.

Mechanical trauma caused by percutaneous coronary intervention is a major factor contributing to subsequent cardiac events, restenosis, and the need for target lesion revascularization (TLR). To minimize this trauma, we developed a Computerized Angioplasty Pressure Sensor and Inflator Device (CAPSID) for gradual inflation. The objective of the present prospective randomized study was to examine whether the use of this novel device reduced TLR, as well as cardiac events, in patients undergoing stenting.

Computerized gradual balloon inflation: a novel strategy of coronary angioplasty superior to a standard manual approach.

Background: Mechanical trauma caused by PCI is a primary reason for restenosis and subsequent target lesion revascularization (TLR). To minimize this trauma, we developed a computerized angioplasty pressure sensor and inflator device (CAPSID) for gradual inflation. The objective of this prospective randomized study was to examine whether use of CAPSID reduces early and late cardiac events in patients undergoing PCI.

Reagentless biosensor based on PQQ-depended glucose dehydrogenase and partially hydrolyzed polyarbutin.

Partially hydrolyzed polyarbutin-containing benzoquinone groups were synthesized by using chemoenzymatic methods. This polymer was used as a mediator for the oxidation of pyrroloquinoline quinone-dependent glucose dehydrogenase. Polymer was covalently attached to the enzyme through the glucose moiety of the polymer and amine residues in the protein.

Synthesis and characterization of polyacrylonitrile nanoparticles by dispersion/emulsion polymerization process.

Polyacrylonitrile nanoparticles in sizes ranging from approximately 35 to 270 nm were prepared by dispersion/emulsion polymerization of acrylonitrile in a continuous aqueous phase in the presence of potassium persulfate as initiator and various alkyl-sulfate and sulfonate surfactants. The influence of various polymerization parameters (e.g.

Diagnosis of pyogenic pelvic inflammatory diseases by 99mTc-HMPAO leucocyte scintigraphy.

Pelvic inflammatory disease (PID) is one of the major health problems of women of child-bearing age. Among the most serious complications of PID is the formation of a tubo-ovarian abscess (TOA). Early diagnosis of this condition may prevent serious surgical complications such as peritonitis and sepsis, which may be fatal.
