Mimicking the Architecture and Dissolution Chemistry of Cancellous Bone Tissue to Optimize the Biocompatibility of Bioactive Scaffolds.

Synthesis of mechanically stable porous scaffolds with an architecture analogous to cancellous bone tissue poses significant challenges to bioactive glass (BG) based scaffolds. This is primarily due to densification and crystallization of the BG's during heat treatment. This study presents a modified BG series (42SiO-xTiO-24NaO-21CaO-13PO, where x = 8 and 16 TiO).

Investigating the structure, solubility, and antibacterial properties of silver- and copper-doped hydroxyapatite.

Hydroxyapatite (HA) powders were synthesized by the wet precipitation method in which two experimental compositions were synthesized (10 mol% Ag-HA and Cu-HA) where the CaNO content was partially substituted with AgNO and Cu(NO ) . X-ray diffraction (XRD) was employed to characterize changes to the HA structure as the dopants (Cu , Ag ) were incorporated into the materials structure. Energy-dispersive X-ray spectroscopy (EDS) determined confirmed the compositions and found that the Ca/P ratio was 1.

Development of Antibacterial Biocomposites Based on Poly(lactic acid) with Spice Essential Oil () for Food Applications.

Among the main biodegradable food packaging materials, poly-lactic acid (PLA) is a commercially successful polymer used notably in the food packaging industry. In this study, active PLA films containing different percentage of anise essential oil (AE) (0, 0.5, 1 and 1.

An epidemiologic survey on the causes of infertility in patients referred to infertility center in Fatemieh Hospital in Hamadan.

Background: Infertility is considered as a major health care problem of different communities. The high prevalence of this issue doubled its importance. A significant proportion of infertility have been related to environmental conditions and also acquired risk factors.
