A novel room-temperature aqueous synthesis for gold nanoparticle-embedded silver cubic mesh nanostructures using AgCl templates via a template-assisted coreduction method is developed. The cubic AgCl templates are coreduced in the presence of AuCl4(-) and Ag(+) , resulting in the reduction of AuCl4(-) into gold nanoparticles on the outer region of AgCl templates, followed by the reduction of AgCl and Ag(+) into silver cubic mesh nanostructures. Removal of the template clearly demonstrates the delicately designed silver mesh nanostructures embedded with gold nanoparticles...

BACKGROUND: The use of synthetic mesh to repair a potentially contaminated incisional hernia may lead to higher failure rates. A biological mesh might be considered, but little is known about long-term results. Both biological and synthetic meshes were investigated in an experimental model of peritonitis to assess their characteristics in vivo. METHODS: Male Wistar rats were randomized into five groups and peritonitis was induced. A mesh was implanted after 24 h...

The therapeutic potential of biological scaffolds as adjuncts to synthetic polymers motivates the engineering of fibers formed using the extracellular matrix (ECM) secreted by cells. To capture the ECM secreted by cells during in vitro culture, a solvent degradable hollow fiber membrane (HFM) was created and utilized as a cell culture platform. 3T3 fibroblasts were injected into the narrow (0.986 ± 0.042 mm) lumina of mesoporous polysulfone HFMs and maintained in culture for up to three weeks. Following cell culture, HFMs were dissolved using NMP solvent and the accumulated ECM was collected...

BACKGROUND: Surgical site infections (SSIs) remain prevalent after ventral hernia repair (VHR). In 2013-2014, a safety-net academic hospital initiated a two-pronged quality-improvement (QI) project: (1) Development and implementation of evidence-based guidelines; and (2) creation of a specialized hernia clinic to manage challenging patients and complex ventral hernias. Our objective was to decrease SSI rates after elective VHR. METHODS: The primary outcome was SSI 30 days post-operatively, which was assessed in aggregate and with a stratified analysis based on case complexity using the χ(2) test...

BACKGROUND: Synthetic mid-urethral mesh slings are the most common primary surgical treatment for stress urinary incontinence (SUI) and have been designated as the standard of care by the American Urogynecologic Society. In recent years, synthetic mesh has come under increased scrutiny by the Federal Drug Administration (FDA) due to concerns over patient safety. This has led to more surgeons and patients preferring Burch colposuspension to treat SUI. CASE: We discuss two cases of suture erosion into the urethra and bladder...

An experimental design mimicking natural plant-microbe interactions is very important to delineate the complex plant-microbe signaling processes. Arabidopsis thaliana-Agrobacterium tumefaciens provides an excellent model system to study bacterial pathogenesis and plant interactions. Previous studies of plant-Agrobacterium interactions have largely relied on plant cell suspension cultures, the artificial wounding of plants, or the artificial induction of microbial virulence factors or plant defenses by synthetic chemicals...

BACKGROUND: Parastomal hernia repair (PHR) remains a challenge with no optimal repair technique. During retromuscular hernia repair, traversing the stomal conduit through the abdominal wall can result in angulation and compression. Widening of traditional cruciate incisions in mesh and/or fascia likely contributes to recurrences. To address these pitfalls, the Stapled Transabdominal Ostomy Reinforcement with Retromuscular Mesh (STORRM) technique utilizing a circular stapler was developed...
