J Med Cases

January 2025

Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University, Okayama City 700-8558, Japan.

Conjunctival malignant melanoma is extremely rare, with no standard of care established at moment. Here we report a 65-year-old woman, as a hepatitis B virus (HBV) carrier, who presented concurrently a liver mass and lower bulbar conjunctival pigmented lesions in the right eye. Needle liver biopsy and excisional conjunctival biopsy showed hepatocellular carcinoma and conjunctival malignant melanoma , respectively.

First-bite syndrome (FBS) is manifested as acute and severe pain in the parotid region occurring at the first bite of a meal. While most cases of FBS arise after surgeries involving the deep lobe of the parotid gland, chemotherapy-induced FBS is extremely rare. Some adverse effects of oxaliplatin resemble FBS, suggesting it may be under-recognized.

Article Synopsis
  • Pancreatic ductal adenocarcinomas (PDAC) are highly aggressive and lack effective treatments; this study examines potential new therapies using rat monoclonal antibodies (mAbs) targeting specific membrane proteins.
  • Key membrane proteins such as HER1-4, MET, S1PR1, LAT1, and CD44v are frequently expressed in PDAC, and targeting them with mAbs demonstrated growth inhibition in various cancer cell lines.
  • High levels of CD44v in PDAC correlate with poor patient prognosis, indicating that targeting CD44v and related proteins could provide new diagnostic and therapeutic avenues for treating this aggressive cancer.

Background: Atrial fibrillation (AF) is the most prevalent form of sustained cardiac arrhythmia, with vascular endothelial growth factor (VEGF) increasingly recognized for its potential role in the pathogenesis of AF through mechanisms involving atrial remodeling, inflammation, and fibrosis. This systematic review aims to synthesize available evidence on the association between VEGF and AF, exploring the implications of VEGF as a biomarker and therapeutic target.

Methods: We conducted a comprehensive search across PubMed, Embase, and Web of Science until November 10 2024, selecting studies based on pre-defined criteria that involve adults with AF and measurements of VEGF levels.

The development of efficient platforms for the evaluation of anti-angiogenic agents is critical in advancing cancer therapeutics. In this study, we exploited an ultrabright semiconducting polymer dots (Pdots) integrating with a three-dimensional (3D) near-infrared-II (NIR-II) fluorescence imaging system designed to assess the efficacy of potent anti-angiogenic agents PX-478 and BPR0C261 in an oral squamous cell carcinoma (OSCC) tumour model, which depends on angiogenesis for dissemination. PX-478, a hypoxia-inducible factor-1α (HIF-1α) inhibitor, and BPR0C261, a microtubule-disrupting agent, were administrated into tumour-bearing mice established using murine MTCQ1 tongue cancer cells through intraperitoneal injection and oral gavage, respectively.

Purpose: Bladder preservation therapy in combination with atezolizumab and radiation therapy (BPT-ART) trial, which was a multicenter, open-label, single-arm phase II study, showed a promisingly high interim clinical complete response (cCR) rate of 84.4% (38/45). In the present study, we aimed to identify potential tissue biomarkers for achieving cCR via BPT-ART.

Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose.

Predictive marker for response to trifluridine/tipiracil plus bevacizumab in metastatic colorectal cancer patients.

BMC Cancer

January 2025

Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, 2-5-1 Shikata-Cho, Kita-Ku, Okayama, 700-8558, Japan.

Objective: Trifluridine/tipiracil (FTD/TPI) is one of the options for late-line treatment of colorectal cancer (CRC). However, the specific patient populations that would particularly benefit from it remain unclear. This study attempted to identify predictive markers of chemotherapy efficacy with trifluridine/tipiracil (FTD/TPI), focusing on the RNA-editing enzyme adenosine deaminase acting on RNA 1 (ADAR1) expression and neutrophil-lymphocyte ratio (NLR).

Protective effects of methylnissolin and methylnissolin-3-O-β-d-glucopyranoside on TNF-α-induced inflammation in human dermal fibroblasts.

Toxicol In Vitro

December 2024

Department of Preventive Medicine, College of Korean Medicine, Gachon University, Seongnam 13120, Republic of Korea. Electronic address:

Methylnissolin-3-O-β-d-glucopyranoside (MNG) and methylnissolin (MN) are pterocarpan derivatives that are found in plants, such as Astragalus membranaceus. There are limited existing studies on the potential health benefits of MNG, and currently there is no evidence to suggest that MNG has any impact on skin-aging. Tumor necrosis factor-alpha (TNF-α) plays a significant role in skin aging by promoting chronic inflammation, damaging skin cells, and impairing the skin's natural repair mechanisms.

The recent discovery of nonvisual photoreceptors in various organs has raised expectations for uncovering their roles and underlying mechanisms. In this work, we identified a previously unrecognized hormone-releasing mechanism in the pituitary of the Japanese rice fish (medaka) induced by light. Ca imaging analysis revealed that melanotrophs, a type of pituitary endocrine cell that secretes melanocyte-stimulating hormone, robustly increase the concentration of intracellular Ca during short-wavelength light exposure.

In this study, we evaluated the impact of Epigalocatechin-3-gallate (EGCG) on biofilm development for 24 and 46 h using high-resolution confocal laser scanning microscopy. EGCG treatment led to the formation of interspaced exopolysaccharide (EPS)-microcolony complexes unevenly distributed on the surface of hydroxyapatite disc, forming a thinner and less complex biofilm structure with significantly reduced biomass, matrix volume, and thickness compared to the NaCl treated group (negative control). At 46 h, the biofilm of the EGCG-treatment group failed to form the bacterial-EPS superstructures which is characteristic of the biofilm in the negative control group.
