[ 1 ] - In-vitro study of Ketoprofen release from synthesized silica aerogels (as drug carriers) and evaluation of mathematical kinetic release models

Silica aerogels are porous and extremely lightweight nano-materials shows interesting properties. These materials, because of biocompatibility, non-harmful to the body and special physical characteristics such as large surface area and low density have great potential for use in a drug delivery system (DDS). The focus of this study is the evaluation of the effects of silica aerogels on improvin...

[ 2 ] - Effect of Adiantum Capillus veneris Linn on an Animal Model of Testosterone-Induced Hair Loss

Androgenetic alopecia is the most common form of hair loss in men. The present study was designed to evaluate the hair growth-promoting activity of a preparation of the Adiantum capillus veneris Linn. (A. capillus veneris Linn.) on albino mice using a testosterone-induced alopecia model. Five groups of albino mice were studied: (A) Testosterone solution only (n=6); (B) Testosterone ‏+ Finasteri...

[ 3 ] - Precipitation Reaction of SDS and Potassium Salts in Flocculation of a Micronized Megestrol Acetate Suspension

In this work attempts were made to evaluate K+-SDS and hydrocolloid polymer-SDS interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. Different dispersions of micronized megestrol acetate and SDS were prepared. KCl and KH2PO4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...

[ 4 ] - Studying the Stability of S-Layer Protein of Lactobacillus Acidophilus ATCC 4356 in Simulated Gastrointestinal Fluids Using SDS-PAGE and Circular Dichroism

Crystalline arrays of proteinaceous subunits forming surface layers (S-layers) are now recognized as one of the most common outermost cell envelope components of prokaryotic organisms. The surface layer protein of Lactobacillus acidophilus ATCC4356 is composed of a single species of protein of apparent molecular weight of 43-46 KDa. Considering the Lactobacillus acidophilus ATCC4356 having the ...

[ 5 ] - Evaluating the In-vitro Antibacterial Effect of Iranian Propolis on Oral Microorganisms

Propolis has traditionally been used in curing infections and healing wounds and burns. Current researches have shown that propolis has antibacterial, antifungal and antiviral actions however, the pharmacological activity of propolis is highly variable depending on its geographic origin. There have been few studies on the effects of Iranian propolis on the oral microorganisms. In this in-vitro ...

[ 11 ] - Facile Synthesis and Characterization of Ibuprofen-mesoporous Hydroxyapatite Nanohybrid as a Sustained Drug Delivery System

The present study deals with the fabrication of ibuprofen-mesoporous hydroxyapatite (IBU-MHA) particles via the incorporation of ibuprofen (IBU)—as a nonsteroidal anti-inflammatory drug—into mesoporous hydroxyapatite nanoparticles (MHANPs) using an impregnation process, as a novel drug delivery device. MHANPs were synthesized by a self-assembly process using cetyltrimethylammonium bromide (CTAB...

[ 13 ] - The Photothermal Effect of Targeted Methotrexate-Functionalized Multi-Walled Carbon Nanotubes on MCF7 Cells

Abstract Purpose: our goal is to reduce the release rate of methotrexate (MTX) and increase cell death efficiency. Methods: Carboxylated multi-walled carbon nanotubes (MWCNT-COOH) were functionalized with MTX as a cytotoxic agent, FA as a targeting moiety and polyethylene amine (PEI) as a hydrophilic agent. Ultimately, MWCNT-MTX and MWCNT-MTX-PEI-FA were synthesized. Methotrexate re...
