The use of a video scanning equipment (Opton Micro-Videomat) for the quantitative determination of alkaline phosphatase activity in histological sections of the rat kidneys is presented. A photomicroscope with a telecamera, a video monitor, a computer and a recorder are incorporated into the system. Automatic measurement, accelerated detection, accuracy,(More)
This study presents the in vitro and in vivo testing of anti-inflammatory drug containing creams, hydrogels and organogels for dermal use. In vitro penetration studies were performed with products by measuring the diffused drug amount through synthetic membranes soaked in isopropyl myristate (IPM). Our developed preparations were investigated under in vitro(More)
The technique of ultra-low volume by ultra-light aircraft for pesticide spray application has been discussed for some time in North America, mainly due to the air worthiness of such an aircraft which was not designed to carry appreciable amounts of payload. The risk factor of such application in insect control has not been determined, while applicator(More)
The aim of the present work was to extend our previous in-vitro drug release studies using semisolid dermatological bases with non-impregnated cellulose acetate membranes. A comparison of the performances of two apparatuses, the more commonly used Franz cell and the new modified USP (mini paddle with ointment holding cell) systems were applied to this work.(More)
This paper addresses the application of fire and smoke simulation and computational fluid dynamics tools to events taking place in the new engineering building on the campus of the University of Montreal. The development steps include 3D CAD modeling of the entire building, geometry transfer and airflow, and fire simulation with enhanced rendering(More)
Complexes of β-cylodextrin with five nucleotides of adenine (A), thymine (T) guanine (G), cytosine (C), and 5-methylcytosine have been investigated using Hatree-Fock (HF) and density functional theory (DFT) calculations of different quality. This work was inspired by recent technological advances made in singlemolecule sequencing of DNA. One molecule of(More)
