Anticancer Molecular Mechanisms of Curcuminoids: An Updated Review of Clinical Trials

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
Curcuminoids remain one of the most studied dietary polyphenols as a cancer prevention and treatment agent. Inflammation and tumor progression are related to the NF‐κB signaling pathway, which is also suppressed by curcuminoids. Curcuminoids prevent the activation of a variety of signaling pathways, including the MAPK, PI3K/Akt, and NF‐kB pathways ...

Re‐evaluation of sucralose (E 955) as a food additive and evaluation of a new application on extension of use of sucralose (E 955) in fine bakery wares

EFSA Journal, Volume 24, Issue 2, February 2026.
Abstract The present opinion deals with the re‐evaluation of sucralose (E 955) as food additive and with the safety of a proposed extension of use in food category (FC) 7.2 ‘Fine bakery wares’. Based on the available data, no safety concerns arose for genotoxicity of sucralose (E 955) and its impurities and degradation products.

Natural Products Targeting Notch Signaling in Cancer: Mechanistic Insights and Food‐Based Chemoprevention Potential

Food Frontiers, Volume 7, Issue 1, January 2026.
The Notch signaling pathway plays a dual role in cancer, acting as both a tumor promoter and suppressor depending on cellular context. This review highlights how natural products modulate Notch signaling to inhibit tumor initiation, progression, angiogenesis, and cancer stem cell maintenance.

A Successful Live Birth After Double Fertility Preservation With Embryo Cryopreservation and MPA Therapy Combined With Hysteroscopic Resection for Metachronous Breast and Endometrial Cancer in Women With Cowden Syndrome: A Case Report

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Case Cowden syndrome is an autosomal‐dominantly inherited rare condition caused by germline pathogenic variants of the PTEN gene. Multiple tumor development at a younger age in this syndrome may warrant different modalities of fertility preservation.

Histopathologic Findings in Three Dogs With Metastatic Carcinoma Presenting With Bronchovascular Bundle Thickening on Computed Tomography

Veterinary Radiology &Ultrasound, Volume 67, Issue 1, January 2026.
ABSTRACT Carcinoma metastasis to the lungs can occur via multiple pathways, most notably via hematogenous, lymphangitic, or aerogenous routes. Computed tomographic (CT) characteristics of these metastatic pathways can vary, with only sparse reports of bronchovascular bundle thickening (BVBT) associated with metastatic carcinoma.
