titanium (ti) is one of the most widely used biomaterials for manufacturing dental implants. the implant surface properties strongly influence osseointegration. the aim of the present study was to in vitro investigate the characteristics of ti dental implants in terms of mutagenicity, hemocompatibility, biocompatibility, osteoinductivity and biological safety. the ames test was used to test the...

I T has been pointed out by Fell & Canti (1934) as a result of their experiments in vitro concerning the early formation of the avian limb skeleton and kneejoint, that the appearance of the articular rudiment is independent of the bloodand nerve-supply as well as of mechanical influences. These authors believe that the formation of articular surfaces occurs in consequence of the differential gr...

Background: In vitro culture of ovarian follicles may preserve fertility in women with premature ovarian failure due to cancer .It seems that creation a condition that could maintain cellular communications and supports growth of follicles to produce mature oocytes appear to be essential. Nitric oxide (NO) has been recently shown to act with a dual action in mouse oocyte meiotic maturation depe...

this study was carried out in order to determine the effects of boron and cold stress on pollen germination of almond hybrids in vitro culture, two different media including the absence and presence of boron (0 mg/l, and 100 mg/l) in 10% sucrose and 1% agar medium at 24°c in dark conditions. the results showed that different treatments had a significant effect on the germination percentage. the...

We compared culture results to investigate the influence of antimicrobial-loaded cement on sonicate fluid culture positivity for the diagnosis of prosthetic joint infection. Fifty-four subjects were assessed. The sensitivities of sonicate fluid culture were 77.8% (14 of 18) in subjects with an antimicrobial-loaded cemented prosthesis and 58.3% (21 of 36) in subjects with an antimicrobial-free p...

Objective(s): The purpose of this study was preparation and evaluation of PVA-Fe3O4 nanofibers as nanocarrier of doxorubicin (DOX) by measuring their drug release together with their in vitro cytotoxicity toward cancer cells at different pH values. Methods: Fe3O4 nanoparticles were synthesized by coprecipitation...

background: fibroblasts are one of the important cells in wound healing. these cells create a proper bed for keratinocytes migration and wound contraction.wound healing in distal limb of horses has complications, such as formation of exuberant granulation tissue (egt). the main factor in this problem is overgrowing of fibroblasts. objectives: the purpose of the present study was to compare fibr...
