Acute appendicitis in the elderly: risk factors for perforation
World Journal of Emergency Surgery, 2014 BackgroundAcute appendicitis is the most common surgical emergency and becomes serious when it perforates. Perforation is more frequent in the elderly patients. The aim of this study was to identify the risk factors of perforation in elderly patients who

Advanced Healthcare Materials, EarlyView.An ex vivo glomerular filtration barrier is engineered using electrospun, biomimetic membranes seeded with human glomerular cells. The model supports fenestrated endothelium and podocyte foot processes under flow, mimics size‐selective filtration, and enables disease modeling with hiPSC‐derived podocytes, offering a powerful platform for studying ...

Sound radiation from a perforated unbaffled plate
, 2007 A model to calculate the sound radiation from an unbaffled perforated plate is proposed. This is achieved by modifying an existing model of an unbaffled plate to include the effect of perforation in terms of a continuously distributed surface impedance ...

Safety Evaluation of Repeated Application of Polymeric Microarray Patches in Miniature Pigs
Advanced Healthcare Materials, EarlyView.This study demonstrates the safety of repeated application of three types of microarray patches (MAPs), hydrogelforming, dissolving, and implantable, over four weeks in miniature pigs. No adverse skin or systemic effects were observed, supporting the clinical potential of MAPs as safe and effective drug delivery platforms.

Time to appendectomy and risk of perforation in acute appendicitis.
JAMA Surgery, 2014 IMPORTANCE In the traditional model of acute appendicitis, time is the major driver of disease progression; luminal obstruction leads inexorably to perforation without timely intervention.
