INTRODUCTION The dural tear is a dreaded complication of lumbar surgery. HYPOTHESIS Our management protocol has made it possible to deal with this problem effectively. MATERIALS AND METHODS Retrospective review of 1359 patients operated between 2000 and 2010. In the event of dural tear, a therapeutic protocol was applied: suturing the dural wound if possible. A collagen patch lined with a l...

2014 We study the conformation of randomly branched, monodispersed polymers both in dilute and concentrated solutions in their reaction bath. We first extend the Zimm-Stockmayer mean field theory to such properties as elasticity and concentration correlations. We then take this mean field theory as a basis for a Flory approach. In a dilute solution, we recover previous results by Isaacson and L...

BACKGROUND Childhood food allergy and asthma rates are increasing. The hygiene hypothesis has been proposed as an explanation for the increased incidence of allergic disease. OBJECTIVE To describe the association of childhood food allergy and asthma with hygiene factors, such as the number of siblings, antibiotic use, infection history, pet exposure, child care exposure, and maternalchild fac...

Coherent anti-Stokes Raman scattering (CARS) spectra are reported for flavin adenine dinucleotide (FAD) and glucose oxidase (beta-D-glucose:oxygen 1-oxidoreductase; EC 1.1.3.4), in resonance with the 450 nm flavin absorption band. Several isoalloxazine ring modes were observed (1635, 1584, 1507, 1416, and 1359 cm(-1)). A 12 cm(-1) increase in one component of the 1359 cm(-1) band upon binding t...
