The Mechanism and Potential Therapeutic Strategies of Vascular Aging

AGING MEDICINE, EarlyView.
The phenotypes of vascular aging vary across different blood vessels. Endothelial dysfunction is observable in the endothelium of all vessels, while vascular structural remodeling primarily occurs in arteries. A decline in organ vascular density mainly affects arterioles, venules, and capillaries, whereas thrombosis predominantly occurs in the ...

In Situ NMR and Kinetics Reveal Origins of Regioselectivity Differences for Epichlorohydrin Ring‐Opening in Lewis and Brønsted Acid Zeolites

Angewandte Chemie, EarlyView.
Regioselectivities for epichlorohydrin ring‐opening over Brønsted and Lewis acid zeolites change by an order of magnitude upon replacing fractions of methanol with acetonitrile co‐solvent. Combining transient operando 13C‐NMR with traditional kinetic measurements reveals that these differences originate from competition between an SN1 pathway through ...

Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

American Journal of Botany, EarlyView.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

CD30 as a Target Molecule in the Diagnosis and Therapy of Lymphomas

American Journal of Hematology, EarlyView.
ABSTRACT The tumor necrosis factor (TNF)‐receptor superfamily 8 receptor CD30 molecule is expressed in all tumor cells of Hodgkin lymphoma and anaplastic large cell lymphoma but is only weakly expressed in a small subset of large lymphoid cells in normal peripheral lymphoid tissues.

An OGT Missense Variant With Impaired Enzyme Activity in a Child With Severe Developmental Delay and Hepatoblastoma

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT O‐GlcNAc transferase (OGT) and its antagonist O‐GlcNAcase (OGA) regulate protein O‐GlcNAcylation, a highly conserved post‐translational modification involved in metabolic sensing. Pathogenic variants in the OGT gene cause an X‐linked congenital disorder of glycosylation (OGT‐CDG) presenting developmental delay, hypotonia, intellectual ...
