In this study, a strain from Muramatsu Park, Gosen City, Niigata Prefecture was isolated using a loop-mediated isothermal amplification (LAMP) assay. The yeast strain was cultured using the mass spore-cell/cell-cell mating method with a sake yeast haploid.

A novel 7-phenoxy-benzimidazole derivative as a potent and orally available BRD4 inhibitor for the treatment of melanoma.

The bromodomain-containing protein 4 (BRD4), which is a key epigenetic regulator in cancer, has emerged as an attractive target for the treatment of melanoma. In this study, we investigate 7-phenoxy-benzimidazole derivative 12, which is a novel BRD4 inhibitor for the treatment of melanoma, by performing scaffold hopping on the previously reported benzimidazole derivative 1. Despite their good oral and intravenous exposure, the compounds obtained by modifying derivate 1 exhibit mutagenicity, which was confirmed by the positive Ames test results.

Assessing the outcomes of posterior thoracic para-aortic lymph node dissection after induction chemotherapy in patients with esophageal squamous cell carcinoma.

Posterior thoracic para-aortic lymph node (TPAN) metastasis is a distant metastasis of esophageal cancer. Several case reports have shown that radical esophagectomy and lymphadenectomy for posterior TPAN improve the prognosis of patients with cStage IVB esophageal cancer and solitary posterior TPAN metastasis; however, the true value of this procedure is unclear. The primary objective of this study was to evaluate the short- and long-term outcomes of lymphadenectomy for posterior TPAN after induction chemotherapy in esophageal cancer.

Total RAMIE with three-field lymph node dissection by a simultaneous two-team approach using a new docking method for esophageal cancer.

Background: Thoracic esophageal cancer surgery using robotic approaches for the thoracic and abdominal parts has recently been reported as total robot-assisted minimally invasive esophagectomy (RAMIE). We herein present the first report of a new technique for esophageal cancer: total RAMIE with three-field lymph node dissection (3FLND) by a simultaneous two-team approach using a new docking method.

Methods: We reviewed 20 patients who underwent total RAMIE with 3FLND by a simultaneous two-team approach at the National Cancer Center East Hospital from March 2023 to September 2023.

Efficiency of conversion surgery for esophageal squamous cell carcinoma with solitary abdominal para-aortic lymph node metastasis.

Purpose: Abdominal para-aortic lymph nodes (PANs) are sites of distant metastasis in esophageal squamous cell cancer (ESCC). The prognosis of patients with Stage IVB ESCC and abdominal PAN metastasis is extremely poor. However, chemotherapy for ESCC has recently been developed, and the effectiveness of combined induction therapy and conversion surgery remains unclear.

A longitudinal study of the influence of work characteristics, work-family status, and social activities on problem drinking: the Japanese civil servants study.

Problem drinking causes a decline in labor productivity among working population. This study examined whether work characteristics, work-family status, and social activities are associated with future problem drinking behavior among Japanese civil servants. A total of 1,535 participants (men: 63.

Development and validation of clinical implementation methods for patient-reported outcomes in Japanese multi-center palliative care units.

Background: Patient-Reported Outcomes (PROs) are recommended for use in clinical oncology. However, they are not routinely used in professional palliative care practices in Japan. The reasons include both patient and healthcare provider factors and the implementation of PROs.

Examination of factors related to problem drinking among the working population: The Japanese civil servants study.

Problem drinking affects not only the health of a population but also the productivity of a nation, especially if it is rampant among the working population. This study examines the association between problem drinking and work characteristics, work-family status, and social situations among the Japanese working population. Multivariable logistic regression analysis was performed on the basis of gender on 3136 participants (men: 65.

Robot-assisted transcervical esophagectomy with a bilateral cervical approach for thoracic esophagectomy.

Background: Thoracic esophageal cancer resection through the neck approach has recently been reported as mediastinoscopic surgery. We present the first report of a new minimally invasive technique for thoracic esophageal cancer: robot-assisted transcervical esophagectomy with a bilateral cervical approach.

Methods: Ten cases of robot-assisted bilateral transcervical esophagectomy performed at the National Cancer Center Hospital East, Japan, from February 2023 to August 2023 were reviewed.

A novel device to assess the oxygen saturation and congestion status of the gastric conduit in thoracic esophagectomy.

Background: In thoracic esophagectomy, anastomotic leakage is one of the most important surgical complications. Indocyanine green (ICG) is the most widely used method to assess tissue blood flow; however, this technique has been pointed out to have disadvantages such as difficulty in evaluating the degree of congestion, lack of objectivity in evaluating the degree of staining, and bias easily caused by ICG injection, camera distance, and other factors. Evaluating tissue oxygen saturation (StO2) overcomes these disadvantages and can be performed easily and repeatedly.

[Management of Postoperative Infectious Complications After Thoracic Esophagectomy].

Although minimally invasive procedures such as thoracoscopic surgery and robot-assisted surgery have become increasingly popular in esophageal cancer in recent years, perioperative management remains a very important topic. However, perioperative management is still an extremely important issue, as esophagectomy is still a highly invasive procedure. Especially in recent years, as the patient population ages, it is expected that we will have more and more opportunities to deal with patients with various pre-existing medical conditions in addition to the original decline in physical function.

A novel imaging technology to assess tissue oxygen saturation and its correlation with indocyanine green in the gastric conduit during thoracic esophagectomy.

Background: Anastomotic leakage in esophagectomy is a serious complication, and assessing blood perfusion in the conduit can help minimize this risk. Indocyanine green is the most widely used method to assess tissue blood flow; however, this technique has disadvantages. Evaluating tissue oxygen saturation in the gastric conduit during thoracic esophagectomy compared with indocyanine green blood perfusion assessment addresses these disadvantages and can be performed easily and repeatedly.

Discovery of a potent, orally available tricyclic derivative as a novel BRD4 inhibitor for melanoma.

The epigenetic regulation of the protein bromodomain-containing protein 4 (BRD4) has emerged as a compelling target for cancer treatment. In this study, we outline the discovery of a novel BRD4 inhibitor for melanoma therapy. Our initial finding was that benzimidazole derivative 1, sourced from our library, was a powerful BRD4 inhibitor.

The feasibility of post-photodynamic therapy salvage esophagectomy in patients with esophageal squamous cell carcinoma treated with definitive chemoradiotherapy.

Background: Photodynamic therapy (PDT) is a minimally invasive salvage treatment for local residual or recurrent lesions that persist after the definitive chemoradiotherapy (dCRT) of esophageal cancer. However, esophageal cancer persistence after PDT is associated with a poor prognosis. Although esophagectomy is a curative treatment option, few studies have evaluated its efficacy.

A comparison of the short-term outcomes between laparoscopic and robotic distal gastrectomy: A retrospective study using a nationwide inpatient database.

Background: Although the safety of robotic distal gastrectomy has been studied in several single-center trials, the nationwide outcomes of robotic distal gastrectomy that meet the requirements of Japanese national health insurance, such as facility case volume and skill level of the surgeon, are still not clear. The objective of this study was to evaluate the short-term outcomes of robotic distal gastrectomy, which was covered by national health insurance, compared to laparoscopic distal gastrectomy.

Methods: We retrieved gastric cancer cases with cStage I to III who underwent laparoscopic distal gastrectomy (15,539 patients) and robotic distal gastrectomy (1,312 patients) between April 2018 and March 2020 from the Diagnosis Procedure Combination database.

[A case of splenic injury after colonoscopy].

An 81-year-old woman lost consciousness and was taken to our hospital 3 days after colonoscopy was performed as a follow-up of endoscopic mucosal resection done 1 year ago for early sigmoid colon cancer detection. She had left hypochondrial pain. Based on abdominal contrast-enhanced computed tomography (CT) findings, she was diagnosed with abdominal bleeding due to injury to the lower splenic pole, and an urgent splenectomy was performed.

The impact of lymphadenectomy on lymph node recurrence after performing various treatments for esophageal squamous cell carcinoma.

Background: Treatment for regional lymph node recurrence after initial treatment for esophageal squamous cell carcinoma (ESCC) differs among institutions. Though some retrospective cohort studies have shown that lymphadenectomy for cervical lymph node recurrence is safe and leads to long-term survival, the efficacy remains unclear. In this study, we investigated the long-term outcomes of patients who underwent lymphadenectomy for regional recurrence after treatment for ESCC.

Microvascular Decompression for Trigeminal Neuralgia: A Prospective, Multicenter Study.
