Regulates the Immune Response and Gut Microbiota in Mice.

Background: Cactus contains dietary fiber and minerals and is expected to have preventive effects against diabetes, arteriosclerosis, and other diseases. Additionally, cactus intake induces the production of short-chain fatty acids derived from the gut microbiota, which might influence immune functions. In this study, we examined the effects of a cactus (: NC)-supplemented diet on lipopolysaccharide (LPS)-induced immune responses and intestinal barrier function.

Phase II study of ramucirumab and docetaxel for previously platinum-treated patients with non-small cell lung cancer and malignant pleural effusion (PLEURAM study).

Background: The prognosis of patients with lung cancer and malignant pleural effusion (MPE) caused by carcinomatous pleurisy is poor. Chemical pleurodesis is commonly performed clinically, however, often has a high failure rate. Furthermore, prolonged sustained drainage and delayed introduction of systemic chemotherapy could increase the risk of worsening the Eastern Cooperative Oncology Group Performance Status (ECOG PS) in the treatment of patients with non-small cell lung cancer (NSCLC).

High risk of multiple gastric cancers in Japanese individuals with Lynch syndrome.

Aim: Lynch syndrome (LS) is a dominantly inherited syndrome characterized by an increased risk for LS associated tumors such as colorectal cancer (CRC) and gastric cancer (GC). However, the clinical benefit of surveillance for GC remains unclear while it has already been recommended for CRC. This study aimed to elucidate the clinical features of GC in Japanese individuals with LS, and the risk of developing multiple GCs to build regional-tailored surveillance programs in LS patients with GC.

Genetic Testing of Japanese Patients with Serrated Polyposis Syndrome: A Multicentric Study.

Objectives: Serrated polyposis syndrome (SPS) is a rare condition associated with an increased risk of colorectal cancer. However, the genetic basis of SPS in Japanese patients remains unclear. The present study therefore aimed to address this omission by identifying candidate causative genes of SPS in Japanese patients.

Analysis of the homodimeric structure of a D-Ala-D-Ala metallopeptidase, VanX, from vancomycin-resistant bacteria.

Bacteria that have acquired resistance to most antibiotics, particularly those causing nosocomial infections, create serious problems. Among these, the emergence of vancomycin-resistant enterococci was a tremendous shock, considering that vancomycin is the last resort for controlling methicillin-resistant Staphylococcus aureus. Therefore, there is an urgent need to develop an inhibitor of VanX, a protein involved in vancomycin resistance.

Curative resection via right hemicolectomy and regional lymph node dissection for colonic adenomatous polyposis of unknown etiology with adenocarcinomas localized in the right side of the colon: a case report.

Background: APC and MUTYH are both well-known colorectal polyposis causative genes. However, 30-50% of colorectal adenomatous polyposis cases are classified as colonic adenomatous polyposis of unknown etiology and lack identifiable pathogenic variants. Although guidelines recommend total proctocolectomy for colonic adenomatous polyposis of unknown etiology with over 100 adenomas, evidence is lacking.

HOIL-1L deficiency induces cell cycle alteration which causes immaturity of skeletal muscle and cardiomyocytes.

HOIL-1L deficiency was recently reported to be one of the causes of myopathy and dilated cardiomyopathy (DCM). However, the mechanisms by which myopathy and DCM develop have not been clearly elucidated. Here, we sought to elucidate these mechanisms using the murine myoblast cell line C2C12 and disease-specific human induced pluripotent stem cells (hiPSCs).

A dataset for analyzing the climate change response of grain quality of 48 Japanese rice cultivars with contrasting levels of heat tolerance.

Climate change has a significant impact on rice grain appearance quality; in particular, high temperatures during the grain filling period increase the rate of chalky immature grains, reducing the marketability of rice. Heat-tolerant cultivars have been bred and released to reduce the rate of chalky grain and improve rice quality under high temperatures, but the ability of these cultivars to actually reduce chalky grain content has never been demonstrated due to the lack of integrated datasets. Here, we present a dataset collected through a systematic literature search from publicly available data sources, for the quantitative analysis of the impact of meteorological factors on grain appearance quality of various rice cultivars with contrasted heat tolerance levels.

Risk of metachronous colorectal cancer after surgical resection of index rectal cancer in Lynch syndrome: a multicenter retrospective study in Japan.

Purpose: This study evaluated the risk of metachronous colorectal cancer (CRC) after resection of index (first) rectal cancer in patients with Lynch syndrome (LS).

Methods: Clinicopathological data of patients with genetically proven LS were retrospectively analyzed in this multicenter Japanese study. The cumulative incidence of metachronous CRC and the overall survival were compared between patients with index rectal cancer (rectal group) and those with index colon cancer (colon group).

[Regimen Selection by Narrative Approach in Patients with Advanced Gastric Cancer-Paclitaxel or Nab-Paclitaxel?].

Background: According to the sixth Gastric Cancer Treatment Guideline, the regimen included nab-paclitaxel(nab-PTX) is a conditional recommendation as second-line treatment for advanced gastric cancer. However, the selection criteria of nab-PTX is not clear.

Method: Questionnaire survey as narrative approach on the problems of paclitaxel premedication, the symptoms due to paclitaxel containing alcohol, and infusion time was conducted for patients who had been treated with paclitaxel.

[Questionnaire Survey on Oral Care and Oral Troubles for Patients with Gastric Cancer Received Chemotherapy].

Background: The actual situation of oral care and oral troubles for patients with gastric cancer received chemotherapy is not clear.

Methods: Questionnaire survey in the form of oral questions was performed for patients with gastric cancer who received chemotherapy from December 2021 to February 2022. The relevance between the survey results and background factors was examined using the χ2 test.

Transcriptomic, Proteomic, and Genomic Mutational Fraction Differences Based on HPV Status Observed in Patient-Derived Xenograft Models of Penile Squamous Cell Carcinoma.

Metastatic penile squamous cell carcinoma (PSCC) has only a 50% response rate to first-line combination chemotherapies and there are currently no targeted-therapy approaches. Therefore, we have an urgent need in advanced-PSCC treatment to find novel therapies. Approximately half of all PSCC cases are positive for high-risk human papillomavirus (HR-HPV).

Treatment-related neuroendocrine prostate cancer with germline mutation treated with olaparib.

Introduction: The efficacy of olaparib for treatment-related neuroendocrine prostate cancer is unknown. Here, we report a case of treatment-related neuroendocrine prostate cancer with a mutation that was treated with olaparib with 1-year efficacy.

Case Presentation: A 75-year-old man initially diagnosed with prostate adenocarcinoma developed treatment-related neuroendocrine prostate cancer after 10-year androgen deprivation therapy.

Baseline ctDNA gene alterations as a biomarker of survival after panitumumab and chemotherapy in metastatic colorectal cancer.

Certain genetic alterations and right-sided primary tumor location are associated with resistance to anti-epidermal growth factor (EGFR) treatment in metastatic colorectal cancer (mCRC). The phase 3 PARADIGM trial (n = 802) demonstrated longer overall survival with first-line anti-EGFR (panitumumab) versus antivascular endothelial growth factor (bevacizumab) plus modified FOLFOX6 in patients with RAS wild-type mCRC with left-sided primary tumors. This prespecified exploratory biomarker analysis of PARADIGM (n = 733) evaluated the association between circulating tumor DNA (ctDNA) gene alterations and efficacy outcomes, focusing on a broad panel of gene alterations associated with resistance to EGFR inhibition, including KRAS, NRAS, PTEN and extracellular domain EGFR mutations, HER2 and MET amplifications, and ALK, RET and NTRK1 fusions.

Chloroquine decreases cardiac fibrosis and improves cardiac function in a mouse model of Duchenne muscular dystrophy.

Background: Duchenne muscular dystrophy (DMD), a severe degenerative skeletal and cardiac muscle disease, has a poor prognosis, and no curative treatments are available. Because decreased autophagy has been reported to contribute to skeletal muscle degeneration, therapies targeting autophagy are expected to improve skeletal muscle hypofunction. However, the role of this regulatory mechanism has not been evaluated clearly in DMD cardiomyocytes.

[A Case of Fibromatosis-Like Tumor Which Was Difficult to Differentiate from Local Recurrence of Ascending Colon Cancer].

A 60s female, who had undergone single-incision laparoscopic ileocecal resection for ascending colon cancer with pathological diagnosis of T3N1bM0, Stage Ⅲb, followed by adjuvant therapy with 8 courses CAPOX 2 years ago, had enhanced- computed tomography(CT)for follow-up and a 15-mm nodule near anastomotic site was found. 18F-fluorodeoxyglucose (FDG)-positron emission tomography(PET)CT revealed abnormal accumulation of 18F-FDG only to the lesion and diagnosis of"anastomotic recurrence"was made. We planned and safely performed resection of the anastomotic site and the nodule.
