Background: There always has been a question about the best age for cochlear implantation (CI) in prelingual deaf children. The age factor in the outcome of cochlear implantation in prelingual deaf children has been the subject of many studies. The aim of the present study was to find the effect of age at the time of implantation on hearing threshold of these children. Methods: One hundred and ...

objective(s): progestrone is a prequisite for pre-implantation angiogenesis and induce decidual angiogenesis. it is unknown the effect of progestrone administration on the endometrium of hyperstimulated mice at pre-implantation time. material and methods: adult female nmri mice were divided in three groups [control group, ovarian stimulated group and progestrone treated mice after ovarian stimu...

Background: A prerequisite for successful embryo implantation is adequate preparation of receptive endometrium and the establishment and maintenance of a viable embryo. The success of implantation further relies upon a two-way dialogue between the embryo and uterus. However, molecular bases of these preimplantation and implantation processes in humans are not well known. Materials and Methods: ...

Objective(s): Progestrone is a prequisite for pre-implantation angiogenesis and induce decidual angiogenesis. It is unknown the effect of progestrone administration on the endometrium of hyperstimulated mice at pre-implantation time. Material and Methods: Adult female NMRI mice were divided in three groups [control group, ovarian stimulated group and progestrone treated mice after ovarian stimu...

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...

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...

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...

Background: HOXA11 and leukemia inhibitory factor (LIF) and basic transcriptional element binding protein1 (BTEB1) are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. In this case-control study, the expression pattern of these mRNA was evaluated in patients with endometriosis at the time of implantatio...
