Methods and materials: The process of our technique is divided into three stages. In the first surgical stage, a 50 cm(3) and 80 cm(3) kidney-shaped expander is implanted under the fatty layer in mastoid region. Overlay the big expander on the small one. After the first surgery stage they are inflated alternately. In the second surgical stage, we remove two skin soft-tissue expanders and fix the Medpor ear framework to the fascial
tissue which is covered by the expanded skin flap wholly without application of fascial flap. In the third stage, we perform the transposition of the auricular lobule to the designated position, construction of the tragus and refinement the new reconstructed ear. From January 2009 to December 2010, 27 patients were treated by this method of total ear reconstruction.
Results: 27 patients acquired symmetrical, subtle contour, prominent reconstructed Emricasan clinical trial auricles. The new reconstructed ear had a good contour and its skin color and texture were nearly the same as the normal surrounding skin. The postauricular sulcus was stable and satisfactory. The postoperative follow-up time ranged from 1 to 3 years. The expanded skin flap took well without necrosis. Exposure of the skin expander occurred in 2 patients (7.4%). The Medpor ear framework was extrused
in one patient (3.7%). In addition, the hematoma was Curaxin 137 HCl observed in 3 patients (11.1%). No other severe complications happened.
Conclusion: Overlying implantation of two skin-soft skin expanders solves the problem of insufficient amount of the skin flap, avoids postauricular skin grafting, PI3K inhibitor simplifies the surgical procedure and shortens the operation time significantly. (C) 2012 Elsevier

“Magnetic activated cell sorting (MACS) with annexin V microbeads recognizes externalized phosphatidylserine (PS) residues on the surface of apoptotic spermatozoa. The successful use of this novel technique applied to a highly apoptotic semen sample before performing intracytoplasmic sperm injection (ICSI) is reported here. The use of annexin V microbeads for selecting non-apoptotic spermatozoa seems to reduce the percentage of altered cells, improving the chance of pregnancy after ICSI.

“Aims and objectives: Due to the close relationship between the cochlea and the peripheral vestibular system, the function of the vestibular system may be impaired in children with sensorineural hearing loss. The aims of this study were to determine the prevalence of impairments of motor performance and dynamic visual acuity, and the nature and extent of interaction between these in children with sensorineural hearing loss between the ages of 4 and 14 years.
Methods: This research utilized a correlational, cross-sectional, descriptive design.
