background: tissue engineering represents very exciting advances in regenerative medicine; however, periodontal literature only contains few reports. emdogain (emd) consists of functional molecules that have shown many advantages in regenerative treatments. this study investigated emd effect on gingival fi broblast adhesion to different membranes. materials and methods: two dense polytetrafl uo...

abstract   background and aim: due to the increasing use of restorative materials, finding a  suitable material with low adhesion rate and colonization of pathogenic  streptococcus mutans has a significant importance. the purpose of this study was the  comparison of the adhesion rate of streptococcus mutans to “nano-hybrid composite” and “amalgam” at 1, 3, and 7 day  intervals. methods and mate...

conclusions the patient reported that he did not feel pain or discomfort throughout the intervention. follow-up visits performed after one, three, six, twelve, and sixteen months demonstrated vitality of the tooth the absence of complications, as well as good esthetic results. laser technology may be used in the treatment of traumatic anterior teeth injury with advantages in terms of quality of...

background and objectives: probiotic bacteria are able to absorb fatty acids present in the culture medium and convert them into intracellular fatty acids, which may affect the physicochemical properties of probiotics. subsequently, changing the composition of cellular fatty acids of probiotics improves the electron acceptance capacity of these microorganisms, and results in an increased adhesi...

background: adhesion is a common complication of gynecology surgery so different barrier agents and solutions have been used during these operations to separate and protect tissues from adhesion after surgery. adept is one of these solutions that have been postulated to reduce the chance of adhesion following gynecolgy surgery. objective: to evaluate the effect of 4% icodextrin in reducing adhe...

introduction: when aesthetics is compromised, dental ceramics are excellent materials for dental restorations; owing to their optical properties and biocompatibility, zirconia ceramics are particularly interesting. self-adhesive resin cements are the most suitable for bonding to zirconia ceramics, but traditional adhesive chemistry is ineffective and surface treatments are required to improve t...

clogging occurs during mechanical tunneling with a tunnel boring machine (tbm) because of adhesion of clayey soils to the cutterhead and conveyor system. the present study examined the effects of water and sand contents on clogging in montmorillonite clayeysoil. testing was carried out using an adhesion test device on 28 samples with different water and sand contents to determine adhesionstress...

objective: in this study we introduced an rgd-containing peptide of collagen iv origin that possesses potent cell adhesion and proliferation properties. this peptide was immobilized on a nanofibrous polycaprolactone/gelatin scaffold after which we analyzed human bone marrow-derived mesenchymal stem cells (hbmscs) adhesion and proliferation on this peptide-modified scaffold. methods: nanofibrous...

objective(s): staphylococcus aureus is an important bacterial pathogen responsible for a variety numbers of nosocomial and community acquired infections. biofilm formation is regarded as an important factor in the establishment of s. aureus infection. the contribution of the genetic background of s. aureus to biofilm formation is poorly understood. the aim of the present work was to genotype s....

background:the polysialylated neural cell adhesion molecule (psa-ncam) is expressed in developing brain. fetal brain damage is caused by different conditions such as seizure and hypoxia. the present study was designed to investigate the effect of maternal seizures on the number of psa-ncam positive cells in pup's hippocampus. methods: female wistar rats were divided into four groups: (a) k...
