Cell lysis of Gram-negative bacteria can be efficiently achieved by expression of the cloned lysis gene E of bacteriophage PhiX174. Gene E expression is tightly controlled by the rightward lambda pR promoter and the temperature-sensitive repressor cI857 on lysis plasmid pAW12. The resulting empty bacterial cell envelopes, called bacterial ghosts, are currently under investigation as candidate v...
Recombinant plasminogen activator (reteplase) is a third generation thrombolytic agent which has been used on coronary artery thrombosis and acute myocardial infarction. Clot lysis assay is usually considered as a unique method to evaluate biological activity of reteplase. In this study biological activity of reteplase was determined by APTT (activated partial thromboplastin time) lysis method....
This paper presents the design and application of microcantilever heaters for biochemical applications. Thermal lysis of biological cells was demonstrated as a specific example. The microcantilever heaters, fabricated from selectively doped single crystal silicon, provide local resistive heating with highly uniform temperature distribution across the cantilevers. Very importantly, the microcant...
We describe the design, fabrication, and successful demonstration of a sample preparation module comprising bacteria cell capture and thermal lysis on-chip with potential applications in food sample pathogen analysis. Plasma nanotexturing of the polymeric substrate allows increase of the surface area of the chip and the antibody binding capacity. Three different anti-Salmonella antibodies were ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Introduction: Myocardial infarction as a leading cause of death in most populations is associated with blood clot formation in coronary artery, and rapid clot lysis is important for patient treatment. Some reports have indicated the effects of some trace elements on blood coagulation and clot lysis. The aim of this study was to evaluate the effects of zinc, copper and aluminum on in-vitro coagu...
Tumor lysis syndrome is rare in hepatocellular carcinoma (HCC), but it has been reported more frequently recently in response to treatments such as transcatheter arterial chemoembolization (TACE), radiofrequency thermal ablation (RFTA), and sorafenib. Tumor lysis syndrome induced by low-dose steroid appears to be very unusual in HCC. We report a patient with hepatitis-C-related liver cirrhosis ...
Background: Tumor lysis syndrome caused by widespread tumor cell damage may lead to electrolyte imbalances and express as metabolic disturbance causing clinical abnormalities. Patients and Methods: All patients younger than 16 years with documented malignancy candidate for chemotherapy, in Hamedan province of Iran were enrolled. Results: Out of 69 cancer patients the laboratory form of tumor ...
