Lower lateral crural turnover flap combined with alar batten graft for the long-term result of the treatment of alar convexities.

Introduction: Concave lower lateral cartilages not only cause an esthetic defect but can also lead to external nasal valve insufficiency. The objective of this article is to analyze the combination of two well-known surgical techniques: turning over the alar cartilages as well as the addition of grafts in order to obtain satisfying esthetic and functional long term results.

Materials And Methods: From August 2016 to July 2018, 62 rhinoplasties, a combination of both primary and revision cases, were performed at the Rouen University Hospital in France.

Fluorescent Biomolecules Capped ZnSe Quantum Dots and Their Photocatalytic Activities.

The preparation of semiconductor Quantum Dots (QDs) with controllable size, shape and doping remains a biggest challenge, especially the size below 10 nm. To date, only scarce attempts have been made on the synthesis of ZnSe QDs using biomolecule-assisted hydrothermal approach. Hence the current research work examines the influence of some amino acids namely L-cysteine, methionine and tyrosine as stabilizing agents in the synthesis of ZnSe nanocrystals.

Fast glycorrhachia and cerebrospinal fluid protein as predictors of sensory block in anesthesia with subarachnoid Ropivacaine.

Background: Identify if glycorrhachia and cerebrospinal fluid protein could influence the time of sensory block to T10, the duration and the metameric block's level, after a standard dose of Ropivacaine.

Methods: 80 patients, ASA I - III undergoing to transurethral prostate resection with spinal anesthesia in a prospected open study were recruited. A 0.
