In a previous study, a novel human corneal-like epithelium model utilizing an immortalized human corneal epithelial cell line (iHCE-NY1) was developed as an alternative to animal models to identify chemicals not classified under the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) and was evaluated following the criteria of Test Guideline 492 of the Organization for Economic Co-operation and Development (OECD). In the present study, our aim was to establish an eye irritation test protocol using the iHCE-NY1 model to classify liquid chemicals under the GHS ocular hazard categories: no effect, no classification (No Cat.), Category 2 (Cat.

Article Synopsis
  • - This study investigated how CT scans measuring lung volume can predict serious outcomes in hospitalized COVID-19 patients, using data from 1,200 patients in 4 hospitals and employing AI to assess lung fields.
  • - Results showed that patients with lower predicted total lung volume (TLC) had significantly higher rates of critical complications like bacterial infections and heart failure compared to those with higher volumes (14.2% vs 3.3%).
  • - The study concluded that lower lung volume on CT scans is linked to worse outcomes and slower recovery in COVID-19 patients, highlighting its potential as a prognostic tool in clinical settings.

Since inorganic nanoparticles have unique properties that differ from those of bulk materials, their material applications have attracted attention in various fields. In order to utilize inorganic nanoparticles for functional materials, they must be dispersed without agglomeration. Therefore, the surfaces of inorganic nanoparticles are typically modified with organic ligands to improve their dispersibility.

  • Anti-CD38 monoclonal antibodies improve outcomes for patients with plasma cell dyscrasia (PCD) but increase the risk of infections like cytomegalovirus (CMV) reactivation.
  • A retrospective study involving 154 PCD patients found that 38% of those tested for CMV reactivation showed positive results, with some experiencing mild symptoms and others developing serious conditions.
  • The reactivation of CMV significantly impacted treatment by causing dose adjustments and delays in anti-PCD therapies, highlighting the need for monitoring during anti-CD38 mAb treatment.

Article Synopsis
  • - This study aimed to compare the effectiveness of two first-line treatments for Helicobacter pylori eradication: a triple therapy featuring vonoprazan, amoxicillin, and metronidazole (VAM) versus another using vonoprazan, amoxicillin, and clarithromycin (VAC).
  • - Conducted in Japan with 124 participants, the trial showed that both treatments yielded similar success rates for eradication, around 91% for VAM and 89% for VAC, without significant differences between them.
  • - The results indicate that VAM can be considered an effective first-line treatment and suggests its classification as a grade B regimen, indicating a good potential for national insurance approval in Japan.

Article Synopsis
  • Granulocyte colony-stimulating factor (G-CSF) is used to prevent febrile neutropenia (FN) in cancer patients, with two types available in Japan: long-lasting PEG G-CSF and short-term non-PEG G-CSF.
  • A systematic review of studies found that PEG G-CSF significantly reduces the incidence of FN compared to non-PEG G-CSF, based on a thorough analysis of 23 articles.
  • The study concludes that a single dose of PEG G-CSF is preferred for primary prevention of FN, as it shows stronger evidence compared to multiple doses of non-PEG G-CSF.

Dengue is a systemic viral infection, and clinical findings vary from asymptomatic to life-threatening, including shock and neurological complications. Despite efforts in vector control, the disease continues to spread worldwide, and the number of annual dengue infections is estimated to be 390 million. For patients with severe dengue, early diagnosis is important; however, owing to the wide range of symptoms and severity, diagnosis can be difficult.

Introduction: Osimertinib is a standard treatment for patients with -mutant NSCLC. Although some osimertinib resistance mechanisms have been identified, nearly 50% of the mechanisms remain to be elucidated. This study was aimed at identifying non-genetic mechanisms underlying osimertinib resistance.

  • * A study using genetically modified Slc17a3 mice found that the plasma levels of 11 biological substances, including 3-indoxyl sulfate, were significantly higher compared to wild-type mice, and that urinary excretion of 3-indoxyl sulfate was reduced in Slc17a3 mice.
  • * The research confirmed that 3-indoxyl sulfate is a new substrate for NPT4, indicating that this transporter plays a role in controlling the levels of this compound in the body by managing its

Objectives: We report the first prospective trial of prostatic urethral lift for the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia in Japan.

Methods: This prospective study was conducted at a single institution and included patients with benign prostatic hyperplasia who underwent prostatic urethral lift based on the Japanese surgical indication. The primary efficacy endpoint was reduced international prostatic symptoms score in the early postoperative period after prostatic urethral lift.

Hydrostatic pressure is a common mechanical stressor that modulates metabolism and reduces cell viability. Eukaryotic cells have genetic programs to cope with hydrostatic pressure stress and maintain intracellular homeostasis. However, the mechanism underlying hydrostatic pressure tolerance remains largely unknown.

The development of van der Waals heterostructures has introduced unconventional phenomena that emerge at atomically precise interfaces. For example, interlayer excitons in two-dimensional transition metal dichalcogenides show intriguing optical properties at low temperatures. Here we report on room-temperature observation of interface excitons in mixed-dimensional heterostructures consisting of two-dimensional tungsten diselenide and one-dimensional carbon nanotubes.

Genome Editing is widely used in biomedical research and medicine. Zinc finger nucleases (ZFNs) are smaller in size than transcription activator-like effector (TALE) nucleases (TALENs) and CRISPR-Cas9. Therefore, ZFN-encoding DNAs can be easily packaged into a viral vector with limited cargo space, such as adeno-associated virus (AAV) vectors, for in vivo and clinical applications.

  • Low Hounsfield unit values from vertebral bone CT scans indicate low bone mineral density (BMD), which is a risk factor for osteoporosis and potentially affects COVID-19 outcomes.
  • A study examined 1,132 Japanese COVID-19 inpatients to see how low BMD relates to severe clinical outcomes, finding that patients with low BMD experienced more critical outcomes, especially during the first four waves of COVID-19.
  • The research revealed that patients requiring oxygen during hospitalization had a significant decrease in BMD over three months, suggesting that low BMD can help predict severe disease in COVID-19 patients and may worsen over time.

The giant panda () is one of the important species in worldwide animal conservation. Because it is essential to understand the disease of giant panda for conservation, histopathological analyses of tissues are important to understand the pathogenesis. However, monoclonal antibodies (mAbs) against giant panda-derived proteins are limited.

The C-X-C motif chemokine receptor-1 (CXCR1) is a rhodopsin-like G-protein-coupled receptor, expressed on the cell surface of immune cells and tumors. CXCR1 interacts with some C-X-C chemokines, such as CXCL6, CXCL7, and CXCL8/interleukin-8, which are produced by various cells. Since CXCR1 is involved in several diseases including tumors and diabetes mellitus, drugs targeting CXCR1 have been developed.

Cysteine (Cys) and its oxidized form, cystine (Cys2), play crucial roles in biological systems and have considerable applications in cell culture. However, Cys in cell culture media is easily oxidized to Cys2, leading to solubility issues. Traditional analytical methods struggle to maintain the oxidation states of Cys and Cys2 during analysis, posing a significant challenge to accurately measuring and controlling these compounds.

  • Granulocyte colony-stimulating factor (G-CSF) is used to reduce the risk of neutropenia and infections during cancer chemotherapy, but its effectiveness for digestive system tumors is still uncertain.
  • A systematic review was conducted to evaluate the effectiveness of G-CSF as primary prophylaxis and its impact on the intensity of chemotherapy for various digestive system tumors.
  • The findings indicated that while G-CSF's use in colorectal cancer chemotherapy is inappropriate, there wasn't enough data to make strong recommendations for other types of digestive cancers.
