Introduction: Ocular metastases from breast cancer, particularly involving the optic nerve, are rare and pose a diagnostic challenge. Typically, optic nerve metastases are believed to originate from nearby choroidal metastases or hematogenous spread through the posterior ciliary arteries. However, there have been some reports of metastases through leptomeningeal dissemination.

This study aimed to evaluate the roles of free fatty acid receptors (FFARs) in the regulation of cancer cell functions under hypoxic conditions, using fibrosarcoma HT1080 cells. HT1080 cells expressed FFAR1, FFAR2 and FFAR3 genes, but not FFAR4 gene.

We included 322 male graduate students at Gifu University. Diagnoses of NAFLD and MASLD were based on the presence of hepatic steatosis on ultrasonography.

However, single-agent checkpoint therapies have yet to show benefit to overall survival (OS) for lower-risk stage III cancers. We evaluated the OS benefit of post-operative immunotherapy in the National Cancer Database (NCDB).

The patient underwent total gastrectomy for gastric cancer at 40 years of age, and he was started on nivolumab at age 48 years for treatment of a recurrent lesion that proved resistant to standard chemotherapy. Nivolumab treatment resulted in complete response, but, after the 136th infusion of the drug at age 53 years, the patient was hospitalized for sudden onset of diabetic ketoacidosis.

Aim: This study aimed to identify the association between sarcopenia, possible sarcopenia, muscle weakness, muscle mass and calf circumference, and the functional outcomes 3 months after stroke.
Methods: In this single-centre prospective observational study, muscle strength, muscle mass, and calf circumference were measured in patients with acute stroke at hospital discharge.
Although various treatments for advanced stages of Kienböck's disease have been reported, clinical evidence demonstrating the efficacy of lunate resection and vascularized os pisiform transfer for Kienböck's disease is limited. Herein, we investigated the clinical and radiographic results of this procedure. We retrospectively investigated eight patients who were followed up for ≥1 year.
View Article and Find Full Text PDFHematite (-FeO) emerges as an enticing material for visible-light-driven photocatalysis owing to its remarkable stability, low toxicity, and abundance. However, its inherent shortcomings, such as a short hole diffusion length and high recombination rate, hinder its practical application. Recently, oxygen vacancies (Vo) within hematite have been demonstrated to modulate its photocatalytic attributes.

A common feature of these techniques is the removal of overlaying mucosa to enable direct biopsies from the SETs. These methods have been synthesized under the collective term "unroofing technique".

We have previously reported that nobiletin inhibits endoplasmic reticulum stress-induced apoptosis in the pancreatic β-cell line INS-1 and that continuous subcutaneous administration of nobiletin suppresses the progression of diabetes by protecting β-cells in type 2 diabetic mice. In the present study, we investigated effects of oral ingestion of Shiikuwasha extract rich in nobiletin on the pathogenesis of type 2 diabetes in mice.

Cavitation impacts due to bubble collapses are harmful phenomena, as they cause severe damage to hydraulic machinery such as pumps and valves. However, cavitation impacts can be utilized for mechanical surface treatment to improve the fatigue strength of metallic materials, which is called "cavitation peening".

However, little is known about the efficacy of EGFR-TKI rechallenge after resistance to first-line (1L) osimertinib. This study aimed to assess the efficacy and safety of EGFR-TKI rechallenge therapy after resistance to 1L osimertinib in a Japanese clinical setting.

HJ affects inflammation-related cytokines and caecal microbiota in mice fed a low-fibre and high-sucrose diet.
Methods And Results: To determine the ameliorative effect of HJ on inflammatory bowel disease, C57BL/6 mice were divided into three groups and fed distilled water (control) or 3% (w/v) dextran sodium sulphate (DSS) in drinking water with normal chow containing 0% or 5% (w/w) HJ powder for seven days.
HIP1-ALK is a relatively rare fusion pattern in ALK-rearranged NSCLC. Existing studies on the efficacy of ALK tyrosine kinase inhibitor (TKI) resistance mechanisms and treatment strategies in HIP1-ALK-rearranged lung cancer are limited. Here, we report the case of an 18-year-old man with HIP1-ALK-rearranged adenocarcinoma who developed BRAF V600E and V1180L mutations after ALK TKI therapy, in whom the administration of BRAF and MEK inhibitors was ineffective.

Mutagenesis studies demonstrated that the S-S bond formation affects not only the stability of the dimer but also the catalytic efficiency of NDPS1. Structural polymorphs in the crystal structures of NDPS1 complexed with its substrate and substrate analog were identified by employing massive data collections and hierarchical clustering analysis.

Regulated intramembrane proteolysis (RIP) is a two-step processing mechanism for transmembrane proteins consisting of ectodomain shedding (shedding), which removes the extracellular domain through juxtamembrane processing and intramembrane proteolysis, which processes membrane-anchored shedding products within the transmembrane domain. RIP irreversibly converts one transmembrane protein into multiple soluble proteins that perform various physiological functions. The only requirement for the substrate of γ-secretase, the major enzyme responsible for intramembrane proteolysis of type I transmembrane proteins, is the absence of a large extracellular domain, and it is thought that γ-secretase can process any type I membrane protein as long as it is shed.

To understand the biological effects of MPs on humans, it is essential to evaluate the response of human cells to model plastic particles that mimic environmental MPs in a sensitive and non-invasive manner. In this study, we investigated the preparation of poly(ethylene terephthalate) (PET) fragments with properties similar to those of environmental MPs by combining photo-oxidative degradation via ultraviolet (UV) irradiation with mechanical pulverization and hydrolysis via ultrasound (US) exposure.

This study aimed to investigate the association between the day of the week and mortality rates after elective esophagectomy using a large-scale clinical database in Japan.
Methods: The data of elective esophagectomies, registered in the National Clinical Database in Japan, for esophageal cancer treatment between 2012 and 2017 were analyzed.
Purpose: To examine the relationships among health literacy, risk perceptions, COVID-19 information overload, health information seeking, and race/ethnicity.
Design: A cross-sectional non-probability community survey conducted between December 2020 and January 2021. A questionnaire was developed in collaboration with a local minority health task force.
