effects of different types of ageing on macro fibre, microfibril and nanofibril reinforced PF composites. The effect of chemical modifications of fibres on the degradability of the composites at different environments also has been analysed. (C) 2013 Elsevier B.V. All rights reserved.”
“Objective: The purpose of this study was to verify if the preservation of residual hearing after cochlear implantation in classic adult cochlear implant candidates implanted with a perimodiolar electrode correlates with the electric thresholds and with speech perception measures.

Study Design: Retrospective study.

Setting: Cochlear Implant Center at a tertiary referral University Hospital.

Patients: Forty-one patients with cochlear

implant were involved in our study. They were subdivided into 2 groups according selleck chemicals llc to the average preoperative hearing loss at the frequencies of 125 and 250 Hz (low-frequency pure tone average [LFPTA]). Group A included 21 patients with a mean LFPTA of 90 dB HL or lower; group B included 20 patients with a mean LFPTA of greater than 90 dB HL. They underwent 12 months’ follow-up after cochlear implantation, including standard audiologic investigation, speech discrimination tests, and electrical measurements.

Results: signaling pathway No significant differences were found in speech perception tests among groups. In group A, hearing was preserved in 8 (group A1) and was lost in 13 patients (group A2);

the postoperative LFPTA was significantly better (p < 0.0001) in A1. Group A1 patients present significantly higher C values (p G 0.0001) than the other 2 groups, and the dynamic range was therefore significantly wider (p < 0.001).

Conclusion: Preservation of residual hearing should be attempted in all cases. In fact, although effects on the speech perception are not evident with the standard evaluation, larger electrical dynamic range can be achieved and may represent a sign of cochlear “”well-being,”" potentially allowing a more complex electric stimulation of the nerve.”
“Transcatheter aortic valve implantation (TAVI) is currently reserved for high or prohibitive surgical-risk PD-1/PD-L1 Inhibitor 3 datasheet patients with aortic valve stenosis. We report on successful TAVI in two Jehovah’s witness patients. It offers a simple and effective treatment of severe aortic valve stenosis in high-risk patients who refuse the use of allogeneic blood and blood products.”
“To clarify the clinical symptoms of the influenza A virus during the 2009 pandemic influenza outbreak, we describe the clinical features of outpatients diagnosed with type A influenza by use of the rapid influenza diagnostic test (RIDT) from September to December 2009. Questionnaires were used to collect prospective data on 1,122 cases with influenza-like illness at our medical institutions.
