Purpose: This study evaluated the efficacy of ninjin'yoeito for alleviating postoperative symptoms after lung cancer surgery.

Methods: Overall, 140 patients who underwent lobectomy were randomized into a conventional treatment group and a ninjin'yoeito group. The primary endpoint was change in the Cancer Fatigue Scale (CFS) score from baseline and the secondary endpoints were the Cancer Dyspnea Scale (CDS) scores, the Kihon Checklist, and respiratory function.

Learning curve of consolers and bedside surgeons fused robotic-assisted thoracoscopic segmentectomy: insights from the initial 100 cases.

Purpose: This study examined the learning curve of segmentectomy using the "fused surgery" approach.

Methods: We retrospectively collected data from 100 patients who underwent segmentectomy via fused robot-assisted thoracoscopy at our institution between September 2020 and February 2024. The learning curve was evaluated using the cumulative sum of the operative times in all cases and was analyzed separately for simple and complex segmentectomies.

Endothelial ROBO4 suppresses PTGS2/COX-2 expression and inflammatory diseases.

Accumulating evidence suggests that endothelial cells can be useful therapeutic targets. One of the potential targets is an endothelial cell-specific protein, Roundabout4 (ROBO4). ROBO4 has been shown to ameliorate multiple diseases in mice, including infectious diseases and sepsis.

Safety and efficacy of new staple-line reinforcement in lung resection: a prospective study of 48 patients.

Purpose: To evaluate the safety and efficacy of new staple-line reinforcement (SLR) in pulmonary resection through a prospective study and to compare the results of this study with historical control data in an exploratory study.

Methods: The subjects of this study were 48 patients who underwent thoracoscopic lobectomy. The primary endpoint was air leakage from the staple line.

Factors affecting the short-term outcomes of robotic-assisted thoracoscopic surgery for lung cancer.

Purpose: Robotic-assisted thoracoscopic surgery (RATS) is a relatively new approach to lung cancer surgery. To promote the development of RATS procedures, we investigated the factors related to short-term postoperative outcomes.

Methods: We analyzed the records of patients who underwent RATS lobectomy for primary lung cancer at our institution between June, 2018 and January, 2023.

Polyglycerol fatty acid ester contributes to the improvement and maintenance of water solubility of amorphous curcumin by suppressing the intermolecular interaction and the diffusion rate of curcumin.

Curcumin (CUR), a polyphenol, is an attractive component of functional foods, owing to various physiological activities. However, CUR is highly hydrophobic, insoluble in water, and difficult to absorb in the body. Here, we report an amorphous CUR formulation containing the dispersant polyglycerol fatty acid ester (PGFE), demonstrating high and stable water solubility.

Console and bedside surgeon fused robot-assisted thoracic surgery.

In the last decade, even thoracic surgery has seen an increase in the use of robotic surgical systems, and robot-assisted thoracic surgery (RATS) is considered one of the main issues. While RATS is associated with solo manipulative freedom and high-definition optical systems, several disadvantages, such as the lack of tactile sensation and difficult learning curves for the whole team, have been raised. Therefore, to overcome these issues, we developed a 'fusion surgery' approach combining a robotic procedure with manual maneuvers, where the table surgeon retracts the lung and staples the pulmonary vasculature and bronchus.

Pulmonary syphilis with a cicatricial variant of organizing pneumonia: a case report.

Background: Syphilis is a chronic disease that progresses in the primary, secondary, latent, and tertiary stages. Pulmonary manifestations of syphilis are rare, and their histological features have not been well-described.

Case Presentation: A 78-year-old man was referred to our hospital because of a solitary nodular shadow in the right middle lung field on a chest radiograph.

Programmed death ligand-1 expression and occult lymph node metastasis in non-small cell lung cancer.

Background: Identifying the preoperative risk factors for lymph node upstaging could contribute to the development of individualized perioperative treatment for patients with non-small cell lung cancer (NSCLC). The current study aimed to evaluate the risk factors for lymph node upstaging, including gene mutation and programmed death ligand-1 expression in patients with resectable NSCLC.

Methods: Data on the clinicopathological characteristics of patients who underwent lobectomy for clinical N0 NSCLC at our institution were collected.

Comparable efficacy and safety of COVID-19 vaccines for patients receiving tegafur-uracil as postoperative adjuvant chemotherapy.

Purpose: Many effective vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been developed, but a weaker response in individuals undergoing anticancer treatment has been reported. This study evaluates the immunogenic status and safety of SARS-CoV-2 vaccines for patients with non-small-cell lung cancer (NSCLC), receiving tegafur-uracil (UFT) as postoperative adjuvant chemotherapy.

Methods: The subjects of this prospective study were 40 patients who underwent surgery for NSCLC and received SARS-CoV-2 vaccines postoperatively.

Intraoperative rapid immunohistochemistry with noncontact antibody mixing for undiagnosed pulmonary tumors.

Knowledge of the histologic type and primary origin of pulmonary tumors is essential when preparing a surgical strategy. Intraoperative diagnosis of hematoxylin and eosin (H&E)-stained frozen sections is the gold standard, but reliable pathology requires time-consuming immunohistochemistry (IHC) to distinguish among histological types/organ origins and to analyze molecular status. The aim of this study was to evaluate the clinical reliability of a new rapid-IHC technique for intraoperative diagnosis of pulmonary tumors.

Effect of myasthenia gravis on the surgical outcomes of patients with thymoma.

Background: Myasthenia gravis (MG) is the most common paraneoplastic syndrome in thymoma. However, the association between MG and postoperative outcomes is controversial. Therefore, we examined the effect of MG on the surgical outcomes of patients with thymoma.

Prognostic value of preoperative plasma fibrinogen levels in resected stage I non-small cell lung cancer.

Background: The number of surgical procedures has increased among patients with early-stage lung cancer. If the poor prognostic factors for stage I non-small cell lung cancer (NSCLC) can be simply validated preoperatively, appropriate treatment will be provided. The current study aimed to evaluate the prognostic value of preoperative plasma fibrinogen levels in patients with resected stage I NSCLC.

Exploring compounds to be used as cosmetic agents that activate peroxisome proliferator-activated receptor alpha.

Objective: The human epidermis is formed by the proliferation and differentiation of keratinocytes adjacent to the basement membrane. The outermost layer, the stratum corneum, is equipped with a barrier function that prevents water evaporation, and intercellular lipids play an important role in this barrier function. When the barrier is functioning normally, evaporation is prevented; however, when barrier function is impaired, moisture evaporates, resulting in dry and rough skin.

Oxidized Regenerated Cellulose Sheets in Postoperative Intrathoracic Adhesions.

Adhesiolysis is often necessary in intrathoracic adhesion during ipsilateral repeat lung resection. This procedure has a risk of surgical complications, including unintentional intraoperative damage of the pulmonary vessels or lung parenchyma. We used an oxidized regenerated cellulose (ORC) sheet to prevent intrathoracic adhesion after lung resection in 55 patients.

HDAC inhibitor, MS-275, increases vascular permeability by suppressing Robo4 expression in endothelial cells.

Roundabout guidance receptor 4 (Robo4) is an endothelial-specific membrane protein that suppresses pathological angiogenesis and vascular hyperpermeability by stabilizing endothelial cells. Robo4 suppresses severe systemic inflammation induced by pathogens and endotoxins and inhibits tumor growth and metastasis, therefore serving as a potential therapeutic target. Although the regulation of Robo4 expression through transcription factors and epigenetic mechanisms has been studied, the role of histone deacetylases (HDACs) has not been explored.

Fibrous bands associated with higher Masaoka stage and poor recurrence-free survival in patients with thymoma.

Background: Fibrous bands (FBs) are one of the histological features in tumors which can be confirmed by hematoxylin and eosin (H&E)-stained slides. FBs have been reported to correlate with malignancy in various tumors. This study aimed to investigate whether the presence of FBs is associated with malignancy in thymoma.

significantly contributes to the proliferation and invasiveness of malignant tumor cells.

Invasion has a significant role in cancer progression, including expansion to surrounding tissue and metastasis. Previously, we assessed the invasive ability of cancer cells using an easy-to-prepare double-layered collagen gel hemisphere (DL-CGH) method by which cancer cell invasion can be easily visualized. The present study examined multiple lung adenocarcinoma and malignant pleural mesothelioma (MPM) cell lines using the DL-CGH method and identified inherently invasive cell lines.

Structural Basis for PPARα Activation by 1H-pyrazolo-[3,4-b]pyridine Derivatives.

Small-molecule agonism of peroxisome proliferator-activated receptor α (PPARα), a ligand-activated transcriptional factor involved in regulating fatty acid metabolism, is an important approach for treating dyslipidemia. Here, we determined the structures of the ligand-binding domain (LBD) of PPARα in complex with 1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid derivatives, which were recently identified as PPARα-selective activators with markedly different structures from those of the well-known PPARα agonists fibrates. The crystal structures of the complexes showed that they form a canonical hydrogen-bond network involving helix 12 in the LBD, which is thought to be essential for PPARα activation, as also observed for fibrates.

PRC2 Components Maintain DNA Hypermethylation of the Upstream Promoter and Regulate Robo4 Expression in Endothelial Cells.

Roundabout4 (Robo4) is an endothelial cell-specific protein that stabilizes the vasculature in pathological angiogenesis and inflammation. We previously determined a 3-kb Robo4 promoter and demonstrated the importance of the upstream region for nuclear factor-kappaB (NF-κB)-mediated promoter activation induced by tumor necrosis factor α (TNFα). This region contains unique genomic features, including promoter region-specific DNA hypermethylation and chromatin condensation; however, the function of the region remains poorly understood.

[Mediastinal Shift Due to the Rapidly Expanded Giant Bulla Probably Caused by the Lung Cancer].

A 39-year-old man was admitted to our hospital with back pain and numbness of the left leg. Computed tomography (CT) showed a giant bulla and tumor in the right lung, mediastinal shift to the left side and lesions suggestive of metastatic sacral tumor. Three days later, the patient visited the emergency room with dyspnea and tachycardia.

Cupid and Psyche system for the diagnosis and treatment of advanced cancer.

In advanced cancer patients, malignant cells invade and disseminate within normal cells and develop resistance to therapy with additional genetic mutations, which makes radical cure very difficult. Precision medicine against advanced cancer is hampered by the lack of systems aimed at multiple target molecules within multiple loci. Here, we report the development of a versatile diagnostic and therapeutic system for advanced cancer, named the Cupid and Psyche system.
