Introduction Surgically inserted rectus sheath catheters (RSCs) are used increasingly for analgesia after cystectomy and other abdominal surgery. Currently, there is little information on the optimal positioning of RSCs to allow maximal spread of local anaesthetic. This study sought to assess the spread of dye injected via RSCs and to highlight the extent of its coverage in a fresh unembalmed cadaveric cystectomy model in order to confirm the nerve endings that are likely to be anaesthetised with RSCs. Methods Four cadavers underwent lower midline incision with limited bladder mobilisation...

BACKGROUND: Gingival recession involves both soft tissue and hard tissue loss. In this evolutionary era of dentistry, newer techniques have evolved for complete coverage of isolated recession defects. Since 2012, vestibular incision subperiosteal tunnel access (VISTA) technique was used with various regenerative membranes to treat multiple recession defects (MRDs). Platelet-rich fibrin (PRF) membrane, a pool of growth factors but have any added advantage to recession coverage techniques is controversial...

Gingival recession is defined as an apical displacement of the gingival margin beyond the cementoenamel junction leading to serious consequences, including exposure of the root surface, loss of periodontal attachment, root sensitivity to hot and cold air, and esthetic problems. The aim of this study was to evaluate the long-term effect of pedicled buccal fat pad (PBFP) alone and with Emdogain in covering severe gingival recession defects and restoring tooth function. A total of 10 severe buccal recession defects in maxillary first molars were selected to be treated with PBFP, with Emdogain (group I; n = 5) or alone (group II; n = 5)...

OBJECTIVE: Titanium-prepared platelet-rich fibrin (T-PRF) is activated with titanium, which results in a more mature and aggregated form than PRF. In our previous studies, we established that the fibrin carpet formed with titanium had a firmer network structure, and longer resorption time in the tissue than the fibrin carpet formed with glass. The purpose of this randomized controlled clinical trial is to compare the effects of autogenous T-PRF and connective tissue graft (CTG). MATERIALS AND METHODS: A total of 114 Miller Class I/II gingival recessions with abrasion defects were treated either T-PRF (63 teeth) or CTG (51 teeth) using a modified tunnel technique...

Posterior indirect adhesive restorations (PIAR) are very common nowadays in clinical practice. The indirect approach is often indicated by a need for cuspal coverage (one or more cusps). With the adhesthetics protocol, the first step is to perform a cavity analysis evaluating the resistance of the tooth after restoration. The structures to be evaluated are, in sequence, the interaxial dentin, ridges, roof of the pulp chamber, and cusps. To improve the strength, the cusps should be covered, when required. The build-up for PIAR is performed with an adhesive technique, and, if possible, with low-shrinkage materials...

PURPOSE: Left atrial arrhythmia substrate assessment can involve multiple imaging and electrical modalities, but visual analysis of data on 3D surfaces is time-consuming and suffers from limited reproducibility. Unfold maps (e.g., the left ventricular bull's eye plot) allow 2D visualization, facilitate multimodal data representation, and provide a common reference space for inter-subject comparison. The aim of this work is to develop a method for automatic representation of multimodal information on a left atrial standardized unfold map (LA-SUM)...

Advances in metagenomics enable high resolution description of complex bacterial communities in their natural environments. Consequently, conceptual approaches for community level functional analysis are in high need. Here, we introduce a framework for a metagenomics-based analysis of community functions. Environment-specific gene catalogs, derived from metagenomes, are processed into metabolic-network representation. By applying established ecological conventions, network-edges (metabolic functions) are assigned with taxonomic annotations according to the dominance level of specific groups...

Connective tissue grafting is a means of developing stable and natural-looking soft-tissue architecture. The use of a subepithelial connective tissue graft (SCTG) has been successful in achieving root coverage and augmenting tissue thickness. Tunnel techniques enable root coverage with results that appear natural. These techniques can be applied to the treatment of dental implants with gingival recession. The purpose of this article is to demonstrate the use of a SCTG and a lateral access pouch in the treatment of multiple gingival recession defects affecting adjacent implants...

Crop wild relatives harbor exotic and novel genetic resources, which hold great potential for crop improvement. Ipomoea imperati is a wild diploid relative of sweet potato with the capability of high salinity tolerance. We compared the transcriptomes of I. imperati under salt stress vs. control to identify candidate genes and pathways involved in salt response. De novo assembly produced 67,911 transcripts with a high depth of coverage. A total of 39,902 putative genes were assigned annotations, and 936 and 220 genes involved in salt response in roots and leaves, respectively...

OBJECTIVES: The use of benchmarks to assess the performance of implants such as those used in arthroplasty surgery is a widespread practice. It provides surgeons, patients and regulatory authorities with the reassurance that implants used are safe and effective. However, it is not currently clear how or how many implants should be statistically compared with a benchmark to assess whether or not that implant is superior, equivalent, non-inferior or inferior to the performance benchmark of interest...
