In a diffusion chamber (DC) system, cells are cultured in vivo - hence making it possible to minimize infection and foreign material contamination. In view of this merit, we devised a technique to combine a DC system and a scaffold to the end of incubating sufficient host cells for grafting. In the present study, PLGA sponge and rat bone marrow cells were encapsulated inside a DC and then place...

Sponge functions were originally proposed for hashing, but find increasingly more applications in keyed constructions, such as encryption and authentication. Depending on how the key is used we see two main types of keyed sponges in practice: inner and outer -keyed. Earlier security bounds, mostly due to the well-known sponge indifferentiability result, guarantee a security level of c/2 bits wi...

BACKGROUND Limited evidence exists in the literature regarding whether a specific mount is preferable to use for processing endoscopically obtained gastrointestinal biopsy specimens. HYPOTHESIS/OBJECTIVES To compare 3 methods of handling endoscopically obtained gastrointestinal biopsy specimens from collection to laboratory processing and to determine if any technique produced superior result...

BACKGROUND Acutely ill patients admitted to the emergency department (ED) constantly require at least one fast and reliable peripheral intravenous (PIV) access. In many conditions (morbid obesity, underweight state, chronic diseases, intravenous drug abuse, adverse local conditions, etc.), PIV placement may be challenging. Ultrasound guidance is a useful tool for obtaining a peripheral intraven...

Controlling the concentration of drugs in pharmaceutical products is essential to patient's safety. In this study, a simple and sensitive HPLC method is developed to quantitatively analyze capsaicin in collagen sponge. The capsaicin from sponge was extracted for 30 min with ultrasonic wave extraction technique and methanol was used as solvent. The chromatographic method was performed by using i...

Large surface areas at an interface between two different materials are desired in many research fields where the interaction between these materials significantly affects the performance of the physical system. This behaviour is illustrated on sponge-like structures, which assign for such a high surface area, and demonstrate the development from bulk material to thin films and a variety of app...

apermanent anti-graffiti clear polyurethane coating, using a silicone additive, was prepared and studied. various techniques, such as contact angle measurements and edx were employed to characterize and investigate thesurface properties of the coatings. the results revealed that with inclusion of silicon additive to clear coating, according to wu method, surface free energy was decreased from 4...

Climatic chamber testing conditions are becoming more demanding. A wide range of temperatures is used to check the quality products and materials, since they constantly being improved. However, there no literature on how components climatic panels react under high temperatures. The present work therefore sets out perform a thermal mechanical characterisation four core materials often in sandwic...

The complex of polyacrylic and polyurethane films physical mechanical properties the operational leather decorated with them has been studied. polyacrylate protective coatings formation is performed on grain face semi-finished leather. 
 150–200 µm thick are formed from polymer solutions aqueous dispersions. Acrylic obtained a dispersion methylbutylacrylate modified by acrylic lcarboxyetha...
