Antitumor Activity of Combined Topoisomerase Inhibition and FLASH Radiotherapy in Head and Neck Carcinoma Biomodels

MedComm, Volume 7, Issue 9, September 2026.
We report a proof‐of‐concept combination of topoisomerase inhibition and FLASH radiotherapy showing enhanced antitumor activity in head and neck carcinoma biomodels, supporting further investigation of this strategy in more clinically representative models and treatment settings. ABSTRACT Locally advanced head and neck carcinoma remains associated with

Evolution of Endoscopic and Histologic Assessment of Eosinophilic Esophagitis in Europe and Evolution of the Diagnostic Delay: Data From the EUREOS EoE CONNECT Registry

United European Gastroenterology Journal, Volume 14, Issue 7, September 2026.
ABSTRACT Background Endoscopy with histopathological assessment of esophageal biopsies is the cornerstone for the diagnosis and phenotypic characterization of eosinophilic esophagitis (EoE). Objective To evaluate temporal trends in endoscopic assessment and biopsy sampling practices for EoE in a large European cohort and their association with temporal

Oxygenaging: A Physiological Framework for Geroscience

Aging Cell, Volume 25, Issue 9, September 2026.
Mechanisms of aging disrupt oxygen homeostasis through three converging processes: oxygen‐cascade impairment, microvascular dysfunction, and molecular maladaptation. “Oxygenaging” integrates these domains to explain how declining oxygen delivery and utilization drive mitochondrial instability and amplify the effect of the hallmarks of aging.

Incidence of Hepatitis B Virus Reactivation in Patients Treated With Immunosuppressive and Chemotherapeutic Agents

Alimentary Pharmacology &Therapeutics, Volume 64, Issue 5, Page 625-634, September 2026.
HBV reactivation incidence varied across immunosuppressive and chemotherapeutic agents. Clinically meaningful HBV reactivation was also observed in patients receiving corticosteroids and conventional immunosuppressive therapies. ABSTRACT Background Data on the incidence of hepatitis B virus reactivation (HBVr) remain limited. In Japan, patients who are

Mechanisms Explaining Increasing Soil Water Repellency With Water Content Below the Permanent Wilting Point: A Review

European Journal of Soil Science, Volume 77, Issue 5, September–October 2026.
This review synthesises evidence from surface science, soil physics and interfacial water studies into a coherent mechanistic framework, proposing that evolving interfacial water hydration underpins increasing soil water repellency with increasing soil water content below the permanent wilting point.

Marek’s Disease Virus Infection of Natural Killer Cells

Microorganisms, 2019
Natural killer (NK) cells are key players in the innate immune response. They kill virus-infected cells and are crucial for the induction of adaptive immune responses. Marek's disease virus (MDV) is a highly contagious alphaherpesvirus that causes deadly
