background:uncontrolled application of diazinon (dzn)can cause environmental contamination and adverse healtheffects on humans or animals. objectives:this study aimed toinvestigate the toxic effects and the level of dzn in serum andtissues of rabbits following a sub acute dermal exposure totoxicant. methods:different doses of dzn were applied dailyto new zealand rabbits through the ear skin in ...

3d imagination of human's organs has become feasible by digital image processing techniques and algorithms via ct or mri images in recent years. in this study, a new method for reverse engineering and biomodelling of hard tissues by catia cloud points' concept has been considered. comparing with the current softwares (e.g. biobuild or mimics) has shown the new method's easiness of implementing ...

objective: human retinal pigment epithelium (hrpe) is a cell monolayer located in the outer part of the retina that is in contact with photoreceptors. in many diseases rpe cells damage. one way for treating this disease is the implantation of intact instead of damaged cells. for this reason different types of substrates have been used for cell cultivation. this study has used alginate and a ble...

objectives:  the efficacy of adding platelet-rich plasma (prp) to demineralized freeze-dried bone allograft (dfdba) in order to improve the clinical and radiographic results obtained in treatment of deep periodontal intrabony defects has yet to be fully elucidated. materials ­and methods: this double blind, split-mouth randomized controlled clinical trial was conducted on 12 patients with two c...

background: development of tissue engineering and regenerative medicine has led to designing scaffolds and their modification to provide a better microenvironment which mimics the natural niche of the cells. gelatin surface modification was applied to improve scaffold flexibility and cytocompatibility. methods: plla/pcl aligned fibrous scaffold was fabricated using electrospinning method. adscs...

conclusions although the aforementioned challenges must still be addressed, the potential of wjmscs in skin regenerative clinical treatments is promising. results similar to bone marrow mscs, wjmscs express major histocompatibility complex (mhc) class i molecules. evidence acquisition according to research conducted by various researchers, wharton’s jelly mesenchymal stem cells (wjmscs) have se...
