For the first time, a convenient copper-catalyzed azide-alkyne cycloaddition (CuAAC, click chemistry) was successfully introduced into injectable citrate-based mussel-inspired bioadhesives (iCMBAs, iCs) to improve both cohesive and wet adhesive strengths and elongate the degradation time, providing numerous advantages in surgical applications. The major challenge in developing such adhesives was the mutual inhibition effect between the oxidant used for crosslinking catechol groups and the Cu(II) reductant used for CuAAC, which was successfully minimized by adding a biocompatible buffering agent typically used in cell culture, 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), as a copper chelating agent...

OBJECTIVE: To evaluate the optimal duration of antimicrobial prophylaxis in patients undergoing "complicated"' major hepatectomy with extrahepatic bile duct resection. BACKGROUND: To date, 4 randomized controlled trials (RCTs) have assessed the duration of antimicrobial prophylaxis after hepatectomy. However, all of these previous studies involved only "simple" hepatectomy without extrahepatic bile duct resection. METHODS: Patients with suspected hilar obstruction scheduled to undergo complicated hepatectomy after biliary drainage were randomized to 2-day (antibiotic treatment on days 1 and 2) or 4-day (on days 1 to 4) groups...

: Both adipose-derived stem cells (ASCs) and stromal vascular fraction (SVF) have been demonstrated to have regenerative properties with therapeutic potential for numerous diseases through local or topical applications. However, it is unclear whether ASC or SVF can be delivered systemically through an intra-arterial infusion. The purpose of this study was to examine the microcirculatory response in vivo on local intraarterial infusion of autogenic ASCs or SVF in a vascular pedicle isolated rat cremaster microcirculation model...

BACKGROUND: Synthetic meshes have been used with varying rates of success in a contaminated setting, although their use is not widely accepted because of concerns for infection. A biologic mesh (BM) is assumed to be more resistant to infection than a synthetic mesh; however, sparse clinical data support this theory. The hypothesis for this study: Uncoated polypropylene synthetic mesh (USM) can be used to obtain a durable repair in the setting of a contaminated abdominal wall reconstruction (AWR) in a single-stage procedure with comparable infectious outcomes to a biologic mesh repair...

Purpose: The autoimmune blistering skin disease pemphigus vulgaris (PV) is caused by autoantibodies against desmosomal adhesion molecules. Patients may suffer conjunctival involvement, yet the underlying mechanisms are largely unclear. We characterized human and murine conjunctiva with respect to the PV autoantigens, and evaluated the effects and mechanisms of PV autoantibodies applied to human conjunctiva ex vivo. Methods: We obtained human conjunctiva specimens from surgical explants and established a short-term culture model to study the alterations induced by antibody fractions of PV patients (PV-IgG)...

The CRISPR/Cas9 genome editing tool has increased the efficiency of creating genetically modified pigs for use as biomedical or agricultural models. The objectives were to determine if DNA editing resulted in a delay in development to the blastocyst stage or in a skewing of the sex ratio. Six DNA templates (gBlocks) that were designed to express guide RNAs that target the transmembrane protease, serine S1, member 2 (TMPRSS2) gene were in vitro transcribed. Pairs of CRISPR guide RNAs that flanked the start codon and polyadenylated Cas9 were co-injected into the cytoplasm of zygotes and cultured in vitro to the blastocyst stage...

PURPOSE: Algorithms for surgical operation planning are evidence-based. However, choices sometimes have to be made between medically equal solutions e.g. for staffing of sought-after operations. Such decisions are heavily influenced by micropolitics and power. The article examines the array of highly manipulated processes around operation theatre allocation of convenient time slots or staff, which play out in various ways in all of the world's main regional surgical cultures. METHOD: Essay supported by empiric data from an ethnographic power-analysis targeted to senior executive surgeons...

The aim of this study was to produce epithelial attachment on a typical implant abutment surface of smooth titanium. A challenging complication that hinders the success of dental implants is peri-implantitis. A common cause of peri-implantitis may results from the lack of epithelial sealing at the peri-implant collar. Histologically, epithelial sealing is recognized as the attachment of the basement membrane (BM). BM-attachment is promoted by activated platelet aggregates at surgical wound sites. On the other hand, platelets did not aggregate on smooth titanium, the surface typical of the implant abutment...

BACKGROUND: Shunt infection is a frequent and serious complication in the surgical treatment in hydrocephalus. Previous studies have shown an attenuated immune response to these biofilm-mediated infections. We proposed that IL-10 reduces the inflammatory response to Staphylococcus epidermidis (S. epidermidis) CNS catheter infection. METHODS: In this study, a murine model of catheter-associated S. epidermidis biofilm infection in the CNS was generated based on a well-established similar model for S...
