Nanoparticle‐Mediated Immunometabolic‐Epigenetic Remodeling Enhances Schwann Cell‐Macrophage Interaction for Sciatic Nerve Regeneration

Advanced Science, Volume 13, Issue 25, 4 May 2026.
A biomimetic Prussian White nanoparticle (PW) is engineered to achieve long‐term local retention and orchestrate immunometabolic‐epigenetic remodeling for sciatic nerve regeneration. PW directly targets hexokinase 2 to suppress glycolysis, thereby elevating α‐ketoglutarate and driving Kdm4a/b‐mediated demethylation of H3K9me3.

A Biochemically “Silent” Aortocaval Paraganglioma in a 19‐Year‐Old Female Causing Intraoperative Hypertensive Crisis: A Rare Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Paragangliomas may appear biochemically silent, yet still behave as functional tumors with severe intraoperative consequences. Normal preoperative catecholamine screening does not exclude the risk of hypertensive crisis during surgery.

Programmed cell death ligands expression in phaeochromocytomas and paragangliomas: Relationship with the hypoxic response, immune evasion and malignant behavior

OncoImmunology, 2017
The hypoxic response underlies the pathogenesis and malignant behavior of PCC/PGL. Regulation of PD-1 receptor-ligand signaling, a therapeutically actionable driver of the anti-tumor immune response, is a hypoxic-driven trait across malignancies.

Two Cases of Hereditary Paraganglioma‐Pheochromocytoma Syndrome in Siblings, Caused by a Novel Succinate Dehydrogenase Complex Subunit D Variant

IJU Case Reports, Volume 9, Issue 3, May 2026.
ABSTRACT Introduction Pheochromocytomas and paragangliomas are increasingly recognized as hereditary malignancies, with ~30%–40% of cases involving germline variants. We report a familial case of hereditary pheochromocytoma‐paraganglioma syndrome caused by a novel variant in the SDHD gene.

Correlation Analysis of 24‐h Minimum Heart Rate Levels and Deceleration Capacity of Heart Rate in Patients With Type 2 Diabetes Mellitus Complicated With Essential Hypertension

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
Sex‐specific 24‐hour minimum heart rate (MHR) stratification in patients with type 2 diabetes mellitus and essential hypertension (T2DM‐EH). Three key findings are shown from subgroup analysis: (1) In the normal MHR group (Group B), advancing age independently predicts reduced deceleration capacity (DC) in both sexes.
