The Africa We Want: A Perspective on the African Code Against Cancer To Be Developed for Sub‐Saharan Africa

International Journal of Cancer, EarlyView.
ABSTRACT Sub‐Saharan Africa (SSA) faces a unique cancer burden, characterized by a disproportionately high mortality‐to‐incidence ratio, a large share of infection‐related cancers, and distinct environmental exposures. Implementation of national policies on primary prevention is limited, and public literacy regarding cancer risk and curability remains ...

Betaine‐, xylitol‐, and extra virgin olive oil–based toothpaste modulates inflammation and oral nitric oxide pathway: Clinical trial in gingivitis

Journal of Periodontology, EarlyView.
Abstract Background Gingivitis is a prevalent and reversible inflammatory condition driven by microbial dysbiosis. Beyond plaque control, interest has grown in oral hygiene formulations capable of modulating inflammation while preserving key microbial functions. Extra virgin olive oil (EVOO), together with xylitol and betaine, has demonstrated clinical

Engineering Photonic Pigments From Titania–Block Copolymer Composites

Macromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.

Decoding Molecular Mechanisms of Pongamia pinnata Phytochemicals in Cancer Therapy

Medicine Advances, EarlyView.
Pongamia pinnata phytochemicals have multiple anticancer mechanisms, including antioxidant, anti‐inflammatory, anti‐metastatic, and apoptosis‐inducing activities through molecular‐level regulation. These bioactive compounds protect normal cells from oxidative stress while promoting reactive oxygen species‐mediated tumor cell death and suppressing ...

Interaction With Surface Spins as a Contribution to Nuclear Magnetic Relaxation of Liquids Adsorbed in Mesoporous Materials

Magnetic Resonance in Chemistry, EarlyView.
Liquids at silica interfaces experience demixing as a consequence of their respective polarity. The distribution of liquids and their primary relaxation contributions are studied by surface modification with OD and radical moieties, respectively. ABSTRACT NMR relaxation of liquids in the presence of solid interfaces, such as silica gel or porous glass,
