Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation

Advanced Science, EarlyView.
Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized

ROS‐Responsive Nanobubbles for Dual‐Enhanced Ultrasound and Magnetic Resonance Imaging of Tumor Oxidative Stress

Advanced Science, EarlyView.
We report the development of biotinylated PEGylated bilirubin‐coated perfluoropentane (bt‐PEG‐BR@PFP) nanobubbles, a novel class of ROS‐activatable and dual‐modality contrast agents that amplify both ultrasound (US) and magnetic resonance imaging (MRI) signals in response to elevated ROS.

Scalable Engineering of Bio‐Manufactured Extracellular Vesicles for Selective Delivery in Ovarian Cancer Patient‐Derived Models

Advanced Science, EarlyView.
Engineered extracellular vesicles displaying Ephrin‐B2 selectively target Ephrin‐B4–expressing ovarian cancer cells, enabling precise delivery in patient‐derived models. This scalable bio‐manufacturing platform reveals a versatile strategy to exploit Ephrin signaling for highly specific therapeutic payload delivery and motivates exploration of tailored

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

Advanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

[Orbital neoplasms in children].

Klinika oczna, 1990
The incidence, diagnosis and clinical picture of the orbital tumors in children are discussed on the basis of 49 personal cases. Discovered was the preponderance of primary non-malignant tumors. The most frequently encountered tumors were angiomas (27 p.c.), dermatomas (19 p.c.) lymphomas (8 p.c.) and among the malignant tumors--rhabdomyosarcoma (6 p.c.
