Introduction: To achieve the best esthetic and functional results of implantation and patient satisfaction, different protocols of implant therapy have been recommended. Immediate implantation can provide the outcome faster than other protocols making it the treatment of choice. The rate of peri-implant bone resorption should be measured clinically and radiographically as bone support is a key ...

Background: Integrins are heterodimeric glycoprotein receptors that regulate the interaction of cells with extracellular matrix and may have a critical role in implantation. The aim of this study was to investigate the effect of ovulation induction on the expression of α4, αv, β1, and β3 integrins in mouse blastocyst at the time of implantation. Methods: The ovarian stimulated and non-stimulate...

performing cochlear implantation in patients with inner ear malformation has always been a matter of dispute. this study was designed to analyze the operative findings,complications, and postoperative performance of patients with inner ear anomalies who underwent cochlear implantation. six patients with inner ear malformations underwent implantation in our academic tertiary referral center from...

background: the opening and closing of the implantation window is important for successful pregnancy in eutherians. the recent study demonstrated that the window of uterine receptivity was prepared by the sole action of progesterone in mice, but the mechanism to close the window remained to be elucidated. methods: the pregnant mice were ovariectomized on the evening on the third day of pregnanc...

purpose: to compare the results of implantation of intraocular lens (iol) haptics in ciliary sulcus versus optic capture through the posterior capsulorrhexis following iol implantation in capsular bag in pediatric cataract surgery. methods: eighteen eyes of nine children with bilateral congenital or developmental cataract were included in this contralateral prospective randomized study. all cas...

background: aggressive embryo and receptive endometrium are necessary for successful implantation. on this time endometrium transformates to receptive state, which permits embryonic implantation. studies about embryonic implantation and endometrial receptivity are always a hot spot in the field of reproductive medicine. objective: to investigate the expression pattern of meis1 during peri-impla...

Recurrent implantation failure (RIF) has many definitions, but usually authors consider RIF, the failure to achieve a pregnancy fallowing 2-6 IVF cycles in which more than 10 high grade embryos were transferred to the uterus. There are a lot of causes for RIF but two main causes of that are related to embryo and endometrium. Chromosomal abnormalities, zona hardening and problems in culture medi...

Implantation metastasis occurs when tumor seeds into a wound or tissue by a significant amount of viable tumor cells. Here we describe the case of a 30-year-old man suffering from pain and swelling of the foot, which was misdiagnosed as a bone cyst. Surgery was performed involving curettage followed by bone grafting. After surgical pathology, the exact diagnosis was revealed as the synovial sar...

transcatheteraortic valve implantation, first introduced in 2002, has been established as an alternative modality for patients deemed not suitable for open-heart surgery. the anatomical vicinity of the atrioventricular node and the his bundle to the non-coronary and rightcoronary aortic cusps predisposes patients to conduction abnormalities in case of severe calcification or mechanical trauma d...

objective: non:union: is defined as a minimum of a 9-month period of time since an injury with no visibly progressive signs of healing for 3 months. recent studies show that application of mesenchymal stromal cells (mscs) in the laboratory setting is effective for bone regeneration. animal studies have shown that mscs can be used to treat non:union:s. for the first time in an iranian population...
