Accelerated surgery versus standard care in hip fracture (HIP ATTACK): an international, randomised, controlled trial
A unique approach to Fontan revision in a cyanotic patient
© 2020 Elsevier B.V. Unilateral pulmonary arteriovenous malformations can develop in heterotaxy patients with single ventricle physiology after Kawashima procedure due to preferential flow streaming to one lung. We present the case of a 25 year old patient with this physiology who presented with resting cyanosis to 75% in room air. Our patient underwent a unique revision to reverse the development of arteriovenous malformations with partial resection of her hepatic vein-right pulmonary artery conduit and placement of new conduit connecting hepatic veins to innominate vein which then drained into left-sided superior vena cava, resulting in favorable outcome
Green synthesis of carbon- and silver-modified hierarchical ZnO with excellent solar light driven photocatalytic performance
Superstructured ZnO has been the focus of intensive study due to its promising diverse applications. Here, we demonstrate a facile synthesis of hierarchical ZnO particles hybridized with carbon and silver via a simplified bioprocess using yeast mold broth. Better than traditional microbial and biomimetic methods, our microbe-free strategy offers superior ease-of-preparation with minimal negative environmental impact. The relevant reaction parameters including zinc precursor concentration, broth pH value, and broth content were systemically investigated to control the particle morphologies from solid microrod to mesocrystals of porous microcylinder, nanodisk, nanocone, nanoflower, and microhamburger. Silver nanoparticles were facilely deposited by photoreduction in the broth. The resultant ZnO@C–Ag composite exhibits a significant improvement in the solar light-irradiated photodegradation of methylene blue solution
