Introduction: Closure of mucosal defects after duodenal endoscopic submucosal dissection (ESD) is important to prevent postoperative adverse events. Previously, we devised an underwater reopenable-clip closure method for effective closure of mucosal defects under endoscopic guidance within the field of view. Recently, the usefulness of a method using a clip with a line passing through an accessory channel to close a mucosal defect has been reported.

Purpose: Decreased irisin levels may be associated with the development of emphysema. Similarly, emphysematous changes may develop in patients with chronic lung allograft dysfunction (CLAD) after living-donor lobar lung transplantation (LDLLT). We investigated the severity of emphysematous changes and the relationship between irisin levels and CLAD after bilateral LDLLT and cadaveric lung transplantation (CLT).

Microorganisms are widely utilized for the treatment of wastewater in activated sludge systems. However, the uncontrolled growth of filamentous bacteria leads to bulking and adversely affects wastewater treatment efficiency. To clarify the nutrient requirements for filament formation, we track the growth of a filamentous bacterium, SP-6 in different nutrient-limited conditions using a high aspect-ratio microfluidic chamber to follow cell-chain elongation and sheath formation.

Upside down stomach (UDS) is a rare type of hiatal hernia. It is categorized by herniation of either the entire stomach or most of the gastric portion of the stomach into the posterior mediastinum. Acute UDS usually presents with abdominal and thoracic symptoms immediately after the stomach rotates, while chronic UDS often has either mild or no symptoms with the entire stomach rotated in the mediastinum.

Article Synopsis
  • Human body model analysis was conducted to evaluate how lumbar and pelvic angles affect the effectiveness of seat belts in reducing injuries from accidents, but no previous relationships were established.
  • The study measured lumbar lordosis (LL) and pelvic angle (PA) in 75 individuals, leading to the creation of a Total Human Model for Safety which underwent simulations under crash test conditions.
  • Results indicated that increasing lumbar lordosis and decreasing pelvic angle improved seat belt positioning, potentially enhancing passenger safety by reducing injury risks during frontal impacts.

Hyperimmunoglobulin E syndrome (HIES) is one of the primary immunodeficiencies characterized by recurrent staphylococcal skin and lung infections that result in lung destruction and critically diminished pulmonary function. Despite the lack of definitive treatment, there have been no reports of successful lung transplantation for HIES patients. We report the case of a 42-year-old woman with HIES with progressive bronchiectasis whose pulmonary infection was controlled before transplantation, and subsequent lung transplantation was uneventful.

Background: A bisresorcinol was isolated as the main constituent of 's trunk (Proteaceae). Recently, resorcinol is applied as an active whitening agent in various cosmetic products. Because of the structural mimic to resorcinol, benefits of the bisresorcinol as an aging-enzyme antagonist were demonstrated in this study.

Cariogenic bacteria, such as () and , produce insoluble and sticky glucans as a biofilm material. The present study demonstrates that a lactic acid bacterium (LAB) named BM53-1 produces a substance that inhibits the sticky glucan synthesis. The BM53-1 strain was isolated from a flower of and identified as .

Tetramethyltin was decomposed in an ion source and the fragment ions produced were identified using a low-energy mass-selected ion beam machine. Dominant fragment ions were found to be H+, CH2+, and Sn+. Subsequently, fragment ions were mass-selected.

  • The study explores the use of 3D convolutional neural networks (3D-CNNs) for accurately segmenting clinical target volumes (CTV) in whole breast irradiation for breast cancer treatment.
  • A 3D-UNet model was trained on three different patient datasets (left, right, and both sides) and achieved high segmentation accuracy, with Dice similarity coefficients averaging around 0.85-0.89.
  • Gradient-weighted class activation mapping (Grad-CAM) was used to visualize and understand where the 3D-UNet was focusing in the breast tissue during segmentation, highlighting its effectiveness and any potential limitations.

We present 2 cases of "hybrid lung transplant," which included sequentially implanting a living lobar graft to 1 side and a cadaveric graft to the other side. This procedure was approved by the institutional review board at Okayama University Hospital. The 2 recipients were diagnosed with severe idiopathic pulmonary fibrosis, and living donor lobar lung transplant was considered; however, 2 appropriate donors were not available.

Background: Cartilage conduction hearing aids (CCHAs) were newly devised and spread fast in Japan since their launch in 2017. However, little knowledge is available for this new device.

Purpose: The aim of this study was to establish the knowledge of CCHAs and suggest their indication.

Although the main cellular target of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is thought to be alveolar cells, the absence of their tractable culture system precludes the development of a clinically relevant SARS-CoV-2 infection model. Here, we establish an efficient human alveolosphere culture method and sphere-based drug testing platform for SARS-CoV-2. Alveolospheres exhibit indolent growth in a Wnt- and R-spondin-dependent manner.

  • Inhaled nitric oxide (NO) therapy for lung transplantation is currently not covered by public health insurance in Japan, prompting a study to evaluate its safety and effectiveness.
  • The research analyzed data from 357 lung transplant patients between 2015 and 2019, revealing that 98% received inhaled NO therapy, primarily during and after surgery.
  • Results indicated significant improvements in oxygen levels and reduced pulmonary pressure, with minimal side effects, suggesting a need for insurance coverage of this therapy in lung transplant procedures.

In the conventional ghost imaging, it requires to illuminate a large number of patterns in order to reconstruct a good quality image under a low signal-to-noise ratio. We propose a new method so called time division ghost imaging to improve the quality of the image in noisy environment. In this procedure, the total number of patterns in the calculation process of the correlation function are divided into the sub-units with fewer illuminated patterns.

Purpose: Anti-human leukocyte antigen (HLA) immunoglobulin (Ig) M production stimulated by an alloantigen is sensitive, making IgM a novel potential marker of allorejection after organ transplantation. This study examined the relationship between the serum levels of anti-HLA IgM early after clinical lung transplantation (LTx) and the post-transplant outcomes.

Methods: Thirty-one consecutive patients who underwent deceased LTx were included.

Article Synopsis
  • - The detection of the SFTS virus early is critical for effective treatment and preventing the spread of the disease, leading to the development of two RT-LAMP methods for diagnosis.
  • - A novel primer/probe set was created for RT-LAMP that successfully detected various strains of SFTSV, including Chinese and Japanese genotypes, after extracting viral RNA.
  • - The simplified RT-LAMP method showed a sensitivity of 84.9% and specificity of 89.5%, proving to be effective in identifying SFTSV in human samples without the need for RNA extraction, with no false positives reported.

Recent advances in endoscopic equipment and diagnostic techniques have improved the detection of dysplasia in the inflamed mucosa of patients with ulcerative colitis (UC). However, it remains difficult to endoscopically identify flat-type dysplasia which has been formerly recognized as invisible dysplasia. In this retrospective, single-center study, we endoscopically identified 10 cases of flat-type-predominant dysplasia by targeted biopsy among 38 intramucosal dysplasia lesions from patients with UC who underwent surgical or endoscopic resection from 2007 to 2017.

We verify that the eigenstate thermalization hypothesis (ETH) holds universally for locally interacting quantum many-body systems. Introducing random matrix ensembles with interactions, we numerically obtain a distribution of maximum fluctuations of eigenstate expectation values for different realizations of interactions. This distribution, which cannot be obtained from the conventional random matrix theory involving nonlocal correlations, demonstrates that an overwhelming majority of pairs of local Hamiltonians and observables satisfy the ETH with exponentially small fluctuations.
