BACKGROUND AND PURPOSE Previous ex vivo biomechanical studies have shown that kyphoplasty with polymethylmethacrylate cement increases vertebral body (VB) strength and restores VB stiffness and height after compression fracture. The purpose of the current study was to determine if a hydroxyapatite cement used as a void filler during kyphoplasty provides mechanical stabilization similar to that ...

BACKGROUND AND OBJECTIVE Zygophyllum simplex is commonly used in Saudi Arabia for the treatment of horny patches of skin and as an anthelmintic, analgesic and anti-inflammatory. The experiment was to aimed at to evaluate the constituents of Zygophyllum simplex extract and their effect on blood biochemical parameters in Wistar male rats. METHODOLOGY The plant extract was orally administered to...

Various properties of mixture products depend on the proportions of the components of the mixture, but not on its amount. In a mixture experiment the mixtures are prepared by mixing the required amounts of mixture components. This paper considers the impact of mixing errors on the statistical analysis of such data.

A simplex-lattice mixture design with response surface methodology was used to evaluate in vitro synergistic antioxidant activity of red, green, and brown Brazilian propolis extract blends. The capacity blends measured using the fluorine method oxygen radical absorption assay (ORAC assay). interaction identified between green extracts, predictive model accused a binary composed 59% 41% extracts...
