Isolation of rat islets of Langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of Hanks' solution into the common bile duct. The identification of the islets was done by techniques including the use of a stereomicroscope against a black background. Vital staining was done by an injection of neutral red solution through t...

introduction: failure to achieve adequate and profound anesthesia in teeth with acute pulp inflammation is a common condition during emergency visits in root canal therapy. many different anesthetic solutions such as morphine and capsaicin have accordingly been examined. mannitol­ an alcoholic sugar with high osmotic pressure level- is applicated for reducing intracranial and post retinal press...

BACKGROUND This study tested a low-volume (20-30 microl/20-30 microg DNA) jet injection method for intradermal delivery of a DNA vaccine. Jet injection offers the advantages of a needle-less system, low-cost, rapid preparation of the injected DNA solution, and a simple delivery system. More than one construct can be injected simultaneously and the method may be combined with adjuvants. RESULT...

This study aims to determine the effect of in-ovo injection L-arginine into local chicken eggs on embryo development and chick performance chicken. A total 160 were incubated using semi-automatic incubator with temperature 37-38C relative humidity 55-65%. The injected solution has a concentration 0.5% (m/v). In treatment was divided 4 groups, first without (control), second 0.2 mL (m/v)/egg, th...

PURPOSE To investigate material density, flow, and viscosity effects on microsphere distribution within an in vitro model designed to simulate hepatic arteries. MATERIALS AND METHODS A vascular flow model was used to compare distribution of glass and resin surrogates in a clinically derived flow range (60-120 mL/min). Blood-mimicking fluid (BMF) composed of glycerol and water (20%-50% vol/vol...

increase of environmental pollution and restricted emission legislations have forced companies to produce automobiles with lower air pollutants. in this respect, discharge of blowby gases into the environment has been prohibited and their recirculation into the combustion chamber is proposed as an alternative solution. in addition, using egr technique to control and reduce nitrogen oxides in in...
