Defining the role of extended saphenofemoral junction ligation: A prospective comparative study [PDF]
, 2000 Objective: This study explores the added effect of extended saphenofemoral junction (SFJ) ligation when the greater saphenous vein (GSV) has been eliminated from participating in thigh reflux by means of endovenous obliteration.

Advanced Healthcare Materials, EarlyView.Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

A First-Principles Study of CdSe Nanoclusters Capped by Thiol Ligands [PDF]
arXiv, 2013 A first-principles study of small CdnSen quantum dots (QDs) (n = 6, 13, and 33) has been performed for the study of QD-sensitized solar cells. We assessed the effects of the passivating thiol-radical ligands on the optimized structure, the energy gap, and on the absorption spectrum.

Perovskite Light‐Emitting Diodes with Quantum Wires and Nanorods
Advanced Materials, EarlyView.This review focuses on low‐dimensional perovskite materials and discusses their applications in light‐emitting diodes (LEDs). Special attention is given to the introduction of perovskite quantum wires and nanorods, two unique types of one‐dimensional (1D) materials, and their interesting optoelectronic properties.

Onset of autocatalysis of information-coding polymers [PDF]
arXiv, 2014 Self-replicating systems based on information-coding polymers are of crucial importance in biology. They also recently emerged as a paradigm in material design on nano- and micro-scales. We present a general theoretical and numerical analysis of the problem of spontaneous emergence of autocatalysis for heteropolymers capable of template-assisted ...

Random-sequence genetic oligomer pools display an innate potential for ligation and recombination
eLife, 2018 Recombination, the exchange of information between different genetic polymer strands, is of fundamental importance in biology for genome maintenance and genetic diversification and is mediated by dedicated recombinase enzymes. Here, we describe an innate
