cochlear implantation is a method used for the treatment of patients with profound hearing loss. this procedure may the accompanied by some major or minor complications. we evaluated the surgical complications of cochlear implantation in fars province (south of iran). a total of 150 patients with cochlear implantation were enrolled in the present study. most of the patients were pre-lingual chi...

Multifocal intraocular lens implantation was studied in 6 eyes with a unilateral cataract due to ocular trauma. Two patients had an uncomplicated traumatic cataract, two patients had a complicated traumatic cataract and two patients had a unilateral primary presenile cataract. Postoperative visual acuity for distance and for near vision, with and without additional spectacle correction, as well...

A pre-implantation genetic diagnosis allows the identification of any genetic abnormalities in an embryo created in vitro; therefore, by exercising this practice, women avoided having to resort to therapeutic abortion, because making such a diagnosis allows you to implant only "healthy" embryos, with diseased embryos being discarded as a result. In Italy there is no legal regulatory body for pr...

Following hatching, pre-elongated conceptuses undergo elongation by intense proliferation, until implantation. We investigated the changes in gene expression associated with these physiological events using human cDNA arrays containing 2370 known genes. Comparison of pre-elongated, elongated, and implanting trophoblasts allowed the determination of 313 expressed genes, 63 of which were differen...

OBJECTIVES To optimize percutaneous coronary intervention (PCI) strategy for unprotected left main (LM) disease, we performed a randomized study: intravascular ultrasound (IVUS)-guided bare-metal stent (BMS) or paclitaxel-eluting stent (PES) implantation after lesion pre-treatment with cutting balloon (CB) for unprotected LM lesions. BACKGROUND Recent studies have shown promising results in t...

Cell differentiation during pre-implantation mammalian development involves the formation of two extra-embryonic lineages: trophoblast and primitive endoderm (PrE). A subset of cells within the inner cell mass (ICM) of the blastocyst does not respond to differentiation signals and forms the pluripotent epiblast, which gives rise to all of the tissues in the adult body. How this group of cells i...

Between 1998 and 2004 approximately 400,000 people died in Germany from cardiovascular disease, with heart valve disease playing a significant role. Heart valve disease can lead to stenoses or insufficiency. In 2006, heart valve operations nationwide increased to 20,000. The implantation of heart valves demands great skill and experience of the heart surgeon. To date, location of implantation w...
