Ultrastructural Study of Microphysiological Systems of the Tumor Microenvironment
Small Science, Volume 6, Issue 4, April 2026.We studied ultrastructural features of microphysiological systems (MPS) of the tumour microenvironment consisting of 3D multicellular tumour structures that were grown in hydrogel‐based cancer‐on‐a‐chip models. We selected two different MPS from our lab as examples and devised a sample preparation technique for their observation under dual‐beam focused

Aging Cell, Volume 25, Issue 2, February 2026.Enhanced ATP hydrolysis, ΔΨm flickering, and destabilized ATP synthase dimers collectively reduce ATP availability in senescent cardiomyocytes. This energy deficit is associated with disrupted Ca2⁺ dynamics and contractility. ABSTRACT Heart disease is the leading cause of death in the elderly population.

Alzheimer's &Dementia, Volume 22, Issue 1, January 2026.Abstract INTRODUCTION Proteins interacting with amyloid beta (Aβ) fibrils could be key to plaque formation in Alzheimer's disease (AD) and represent potential biomarkers and therapeutic targets. Previous proteomic studies using microdissected plaques might have captured non‐specific components rather than true Aβ interactors.
