Article Abstract
Purpose: In Japan, transabdominal preperitoneal (TAPP) inguinal hernia repair is performed by firmly pulling the peritoneum inwards to lift it from the underlying deep layer of subperitoneal fascia. It decreases the postoperative pain and discomfort in the inguinal area. The aim of this study was to evaluate the feasibility of the sandwich approach, which is a new technique for creating a preperitoneal space.
Methods: The operation was performed via the sandwich approach. We made sure to protect the preperitoneal fascia areolar layer when making the preperitoneal space.
Results: We performed TAPP in 745 patients (876 hernias) treated between October 2006 and April 2015 at Himeji Medical Center and Kurashiki Central Hospital. Before October 2010, we did not use the sandwich approach, and recurrence was observed in three patients. From October 2010, we always used the sandwich approach and never experienced any cases of recurrence. Clavien-Dindo classification Grade 3 or higher postoperative complications occurred in 6 patients (0.8%) between October 2006 and April 2015. Mesh-related ileus was the most frequently observed morbidity. There were no cases of vas differentia or spermatic vessel injury, postoperative chronic pain, or urinary retention.
Conclusion: The sandwich approach is feasible as another standard dissective procedure for TAPP.

As the most dangerous mycotoxin, aflatoxin B1 (AFB1) has caused some food safety issues to be concerned. In this study, a simultaneous detection and degradation method towards AFB1 was established. Covalent-organic frameworks (COFs) were firstly synthesized and directly in situ deposited on the stainless-steel mesh, which would trigger the free-radical polymerization of acrylamide to form a hydrogel coating.

The rapid advancement of implantable medical electronic devices has spurred substantial research into implantable energy storage systems. However, the presence of multiple film resistors in traditional sandwich structures impedes further enhancements in the electrochemical performance of supercapacitors and may result in contact failures between electrodes and separators or catastrophic short-circuit failures during tissue deformation. This study introduces a novel approach for fabricating all-in-one Zn-ion hybrid supercapacitors, which effectively mitigates performance degradation and safety concerns arising from interfacial issues.

Giant cell tumor (GCT) of the bone, although benign, demonstrates local aggressiveness, a potential for recurrence, and, in rare instances, malignant transformation. Functional preservation is crucial in cases involving the articular surface, often utilizing the Sandwich Technique. We propose an enhanced reconstruction method using the inner table of the iliac crest in a reverse fashion, offering a more anatomically contoured proximal tibial plateau and reducing donor site morbidity compared to tricortical iliac crest grafting.

We report the performance of solid-state ceramic supercapacitors (SSCs) based on a novel composite electrolyte comprising aluminum-doped lithium lanthanum titanate perovskite, LiLaTiAlO (Al-doped LLTO), and the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF). Rietveld refinement of X-ray diffraction data confirms the preservation of the tetragonal perovskite phase after Al substitution, indicating structural stability of the host lattice. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy further corroborate the successful incorporation of Al without forming secondary phases.
