Long-Term Survival After Pneumonectomy for Major Hemoptysis in Advanced Non-Small Cell Lung Cancer.

A 65-year-old man was admitted for a tissue biopsy of suspected right middle and lower lobe lung cancer with multiple bone metastases. During hospitalization, he started to cough up blood, which recurred after intubation. The patient experienced asphyxia, which led to cardiopulmonary arrest, but was successfully resuscitated.

Surgical indications for pleurectomy/decortication in pleural mesothelioma based on the newly revised 9th edition of the tumour-node-metastasis classification.

Objectives: The MARS2 trial questioned the efficacy of curative intent surgery for pleural mesothelioma (PM), while real-world clinical data from Japan suggest a favourable prognosis in surgical cases, indicating survival benefits in selected patients. The newly revised 9th edition of the tumour-node-metastasis (TNM) classification introduces a novel indicator based on pleural thickness.

Methods: We conducted a retrospective evaluation of patients with PM who underwent pleurectomy/decortication between 2012 and 2022.

Development of a seroepidemiological tool for bat-borne and shrew-borne hantaviruses and its application using samples from Zambia.

Background: Rodent-borne orthohantaviruses are the causative agents of hemorrhagic fever with renal syndrome and hantavirus pulmonary syndrome. Apart from the classic rodent-borne hantaviruses, numerous species of hantaviruses have been identified in shrews and bats; however, their antigenicity and pathogenicity are unknown. This study focused on developing a serological method to detect antibodies against bat- and shrew-borne hantaviruses.

Two amino acid pairs in the Gc glycoprotein of severe fever with thrombocytopenia syndrome virus responsible for the enhanced virulence.

Severe fever with thrombocytopenia syndrome (SFTS) is a significant public health concern, with a high fatality rate in humans and cats. In this study, we explored the genetic determinants that contribute to the different virulence of SFTS virus (SFTSV) based on Tk-F123 and Ng-F264 strains isolated from cats. Tk-F123 was 100% lethal in type I interferon receptor-knockout mice, whereas Ng-F264 exhibited no fatality.

A case of salvage surgery following chemoradiotherapy and durvalumab for initially unresectable superior sulcus tumor with N3 involvement.

Background: Durvalumab after chemoradiation (PACIFIC regimen) provides favorable treatment outcomes for unresectable stage III non-small cell lung cancer (NSCLC). The feasibility of salvage surgery after the PACIFIC regimen has been reported in some studies; however, its efficacy remains unclear. We herein present the first case of salvage surgery after the PACIFIC regimen for a superior sulcus tumor with N3 involvement, in which a pathological complete response was achieved.

The seven-day cumulative post-esophagectomy inflammatory response predicts cancer recurrence.

Background: The relationship between postoperative cumulative systemic inflammation and cancer survival needs to be investigated. We developed an approach to the prognostication of postoperative esophageal cancer by establishing low and high cut-off values for the C-reactive protein (CRP) area under the curve (AUC) at 7 and 14 days after esophagectomy.

Methods: One hundred and twenty-five consecutive patients with biopsy-proven invasive esophageal squamous cell carcinoma (SCC) who underwent esophagectomies were evaluated.

Development of a determination method for quality control markers utilizing metabolic profiling and its application on processed Zingiber officinale Roscoe rhizome.

This study established an Orthogonal Partial Least Squares (OPLS) model combining H-NMR and GC-MS data to identify characteristic metabolites in complex extracts. Both in metabolomics studies, and natural product chemistry, the reliable identification of marker metabolites usually requires laborious isolation and purification steps, which remains a bottleneck in many studies. Both ginger (GR) and processed ginger (PGR) are listed in the Japanese pharmacopeia.

Heavy Particle Clustering in Inertial Subrange of High-Reynolds Number Turbulence.

Direct numerical simulation of homogeneous isotropic turbulence shows pronounced clustering of inertial particles in the inertial subrange at high Reynolds number, in addition to the clustering typically observed in the near dissipation range. The clustering in the inertial subrange is characterized by the bump in the particle number density spectra and is due to modulation of preferential concentration. The number density spectrum can be modeled by a rational function of the scale-dependent Stokes number.

Prognostic factors for gastric cancer patients aged ≥ 85 years.

Background: As gastric cancer patients aged ≥ 85 years have a short life expectancy and often die from other diseases such as pneumonia, indications for surgery are controversial. In this study, we retrospectively analyzed the prognostic factors of elderly patients with gastric cancer who are candidates for curative gastrectomy.

Methods: Among 114 patients aged ≥ 85 years with gastric cancer at our hospital between 2010 and 2019, prognostic factors were examined using the Cox proportional hazards model in 76 patients excluding those with cStage IVB or endoscopic submucosal dissection.

Involvement of SARS-CoV-2 accessory proteins in immunopathogenesis.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the largest single-stranded RNA virus known to date. Its genome contains multiple accessory protein genes that act against host immune responses but are not required for progeny virus production. The functions of the accessory proteins in the viral life cycle have been examined, but their involvement in viral pathogenicity remains unclear.

Sarcomatoid malignant pleural mesothelioma: a case of long-term recurrence-free survival following curative intent surgery alone.

Background: Curative intent surgery may be indicated for some patients with resectable early stage malignant pleural mesothelioma (MPM). However, sarcomatoid MPM is a highly aggressive subtype for which curative intent surgery is generally not recommended.

Case Presentation: We present the case of a 63-year-old man who presented with dyspnea and chest tightness.

[A Study on the Scientific Reliability of Notification Data in the Foods with Function Claims].

We conducted a comprehensive survey of Foods with Function Claims (FFC) submitted from April to August 2022 to examine the scientific reliability of the systematic review (SR), which is the basis for functional claims. The results of the review of 611 functional claims for 398 products showed that there were 121 functionally active substances and 87 health claims (Hc) that were labeled, with some functionally active substances having multiple functions. SRs, meta-analyses, and clinical studies were submitted as the basis of functionality for 87%, 10%, and 3% of the reports, respectively.

Akaluc bioluminescence offers superior sensitivity to track dynamics of SARS-CoV-2 infection.

Monitoring viral dynamics can improve our understanding of pathogenicity and tissue tropism. Because the gene size of RNA viruses is typically small, NanoLuc is the primary choice for accommodation within viral genome. However, NanoLuc/Furimazine and also the conventional firefly luciferase/D-luciferin are known to exhibit relatively low tissue permeability and thus less sensitivity for visualization of deep tissue including lungs.

Outcomes and pathologic response of primary lung cancer treated with tyrosine kinase inhibitor/immune checkpoint inhibitor before salvage surgery.

Purpose: Advances in primary lung cancer drug therapy have extended patients' survival, including patients with stage IV disease. This study assessed the safety and effectiveness of salvage surgery following tyrosine kinase inhibitor (TKI) or immune checkpoint inhibitor (ICI) therapy in primary lung cancer.

Methods: A retrospective chart review was conducted of 2050 primary lung cancer surgeries performed at our institution between 2012 and 2022.

Screening of growth inhibitors for epithelial-mesenchymal transition-induced cells by TGF-β from plant-based sources identified the active compound hydroxychavicol from Piper bitle.

Epithelial-mesenchymal transition (EMT) has recently been associated with cancer invasion, metastasis, and resistance. In our previous study, we discovered nanaomycin K, a natural growth inhibitor for EMT-induced Madin Darby canine kidney (MDCK) cells, from the cultured broth of actinomycetes. However, the screening method was undeveloped, because the activity of nanaomycin K was discovered accidentally.

Inhibition of G protein-coupled receptor 68 using homoharringtonine attenuates chronic kidney disease-associated cardiac impairment.

Chronic kidney disease (CKD) induces cardiac inflammation and fibrosis and reduces survival. We previously demonstrated that G protein-coupled receptor 68 (GPR68) promotes cardiac inflammation and fibrosis in mice with 5/6 nephrectomy (5/6Nx) and patients with CKD. However, no method of GPR68 inhibition has been found that has potential for therapeutic application.

[A Case of Liver Metastasis of Gastric Cancer Successfully Treated with SOX plus Nivolumab].

An 82-year-old, male. He visited his local doctor with a chief complaint of dyspnea on exertion. Anemia was noted, and upper gastrointestinal endoscopy was performed, which revealed an ulcerative lesion in the gastric antrum.

Improved quantitative analysis of tenuifolin using hydrolytic continuous-flow system to build prediction models for its content based on near-infrared spectroscopy.

This study used two types of analyses and statistical calculations on powdered samples of Polygala root (PR) and Senega root (SR): (1) determination of saponin content by an independently developed quantitative analysis of tenuifolin content using a flow reactor, and (2) near-infrared spectroscopy (NIR) using crude drug powders as direct samples for metabolic profiling. Furthermore, a prediction model for tenuifolin content was developed and validated using multivariate analysis based on the results of (1) and (2). The goal of this study was to develop a rapid analytical method utilizing the saponin content and explore the possibility of quality control through a wide-area survey of crude drugs using NIR spectroscopy.

[A Case of Stage Ⅳc dMMR Transverse Colon Cancer with Complete Response to Combination Therapy with Immune Checkpoint Inhibitor in Stage ⅣB Lung Adenocarcinoma].

The patient is a 72-year-old man. He was diagnosed as a duplication of left upper lobe lung adenocarcinoma cStage ⅣB and transverse colon cancer cStage Ⅳc. Because he had symptoms of atelectasis and esophageal stricture due to the progression of lung cancer, we decided to precede immunochemotherapy(CBDCA plus PEM plus pembrolizumab)for lung cancer.

Salvage pleurectomy/decortication following immunotherapy for malignant pleural mesothelioma.

Salvage surgery following immunotherapy is a promising treatment option for advanced malignant tumour. However, only a few cases of salvage surgery for malignant pleural mesothelioma (MPM) have been reported. This retrospective study was conducted to assess the feasibility of salvage surgery following immunotherapy for initially unresectabele MPM.

Design of an Anti-HMGB1 Synthetic Antibody for Ischemic/Reperfusion Injury Therapy.

High-mobility group box 1 (HMGB1) is a multifunctional protein. Upon injury or infection, HMGB1 is passively released from necrotic and activated dendritic cells and macrophages, where it functions as a cytokine, acting as a ligand for RAGE, a major receptor of innate immunity stimulating inflammation responses including the pathogenesis of cerebral ischemia/reperfusion (I/R) injury. Blocking the HMGB1/RAGE axis offers a therapeutic approach to treating these inflammatory conditions.
