The Journal of Physiology, EarlyView.Abstract figure legend Graphical abstract of the proposed Ro5‐4864 mechanism of action via p62‐Keap1‐Nrf2 axis in heart failure. TSPO, the 18‐kDa mitochondrial translocator protein of the outer mitochondrial membrane, can directly interact with p62 (also known as SQSTM1), which is crucial for the degradation of damaged mitochondria by autophagy ...

National and Subnational Models of Care That Support Primary Health Care: A Mixed‐Methods Study
The International Journal of Health Planning and Management, Volume 41, Issue 3, Page 490-506, May 2026.ABSTRACT In 2020, the World Health Assembly called on countries to reorient their models of care (MOCs) toward primary health care (PHC). This study's objectives were to (a) describe common use of the concept of MOC; and (b) identify implemented MOCs and their components that support PHC at national and subnational levels. A scoping review charted data

Scratch‐Healing of Conjugated Polymers: Flexibly Linked PTB7‐Th Copolymers and Their Blends
Macromolecular Chemistry and Physics, Volume 227, Issue 9, 15 May 2026.Flexibly‐linked conjugated polymers based on the donor polymer PTB7‐Th are capable of scratch healing. A higher linker content leads to higher “mobility,” which is required for the healing process. However, the optical properties are impaired. Blends of donor polymers with high and low linker content can solve this dilemma as they provide sufficient ...

Introducing Reflected GNSS TEC Data Into ANCHOR Ionospheric Data Assimilation Model
Space Weather, Volume 24, Issue 5, May 2026.Abstract ANCHOR is a novel data assimilation (DA) algorithm developed at the U.S. Naval Research Laboratory to improve ionospheric nowcasting by increasing accuracy and decreasing computational cost. As a parameterized DA model, ANCHOR represents the ionosphere using physical parameters such as the F2 layer peak (Nm $Nm$F2), which characterizes a ...
