objective: the lrr (leucine rich proteoglycans) is a molecular recognition motif found in proteins with some roles in cell adhesion, signal transduction, dna repair and rna processing. opticin is a member of this family. takanosu et al (2001) detected messenger rna expression of mouse opticin in the eye, heart, brain, testis, thyroid and epididymis by dot blot hybridization. in this study, exp...

background: plantar fasciitis (pf) is a common foot complaint, affects both active sportsmen and physically inactive middle age group. it is believed that pf results from degenerative changes rather than inflammation. platelet?rich plasma (prp) therapy has been introduced as an alternative therapy for pf. this study is aimed to systematically review to the effectiveness and relevant factors of ...

background: recently, we have shown that peroxisomal protein expression was induced upon retinoic acid treatment in mouse embryonic stem cells during the process of neurogenesis. thus, characterization of the respective promoter could elucidate the molecular aspects of transcriptional regulation of this gene. methods: using the conventional software programs for promoter prediction, a putative ...

objectives effect of using autologous platelet-rich plasma (prp) on pain reduction in patients with pilonidal abscess, subjected to extensive surgical removal tissue, was investigated through a clinical trial. patients and methods the trial was conducted on two groups from the center for surgical research at mashhad university of medical sciences located at ghaem hospital in mashhad city in 201...

objective: at present, growth factor-containing products such as enamel matrix derivatives, recombinant bone morphogenetic protein (rh-bmp), recombinant platelet derived growth factor and platelet rich plasma (prp) have gained increasing attention. prp is an autologous source of platelet growth factors used to enhance healing of soft and hard tissues. prp has gained popularity due to its autolo...

the clinical use of prp therapy in the practical setting of orthopaedic fields is increasing partly because of the accessibility of devices that are used in outpatient preparation and delivery. another reason is the strong advertisement of prp procedures as the ultimate treatment and novel technology for knee problems by a few orthopaedic surgeons based on claims of abundant scientific evidence...

background: osteoarthritis is a disabling musculoskeletal disease with no definite treatment. this study compared the effect of platelet-rich plasma (prp) and transcutaneous electrical nerve stimulation (tens) plus exercise in the treatment of patients with knee joint osteoarthritis.   methods : 54 eligible patients with knee osteoarthritis were randomly allocated into two groups. (irct20121106...

the influence of increasing the sio2/k2o molar ratio on the electrochemical action of a waterbornepotassium silicate zinc-rich coating was investigated by means of electrochemical impedancespectroscopy (eis) and corrosion potential (ecorr) measurements. the eis results showed thatincreasing the sio2/k2o molar ratio in the range of 3.135 to 5 by the addition of nano-sio2 to theresins improved th...

background: high density concrete is extensively used for efficient radiation attenuation in radiotherapy rooms and nuclear reactors. over the past eight years, some efficient galena-based concrete samples for shielding x or gamma rays was produced. the goal of this study was to produce a novel high density concrete against neutron and photon radiations using tourmaline and galena. materials an...
