Ultraviolet spectrophotometry of three LINERs

open access: yesThe Astrophysical Journal, 1986
Three galaxies known to be LINERs were observed spectroscopically in the ultraviolet in an attempt to detect the presumed nonthermal continuum source thought to be the source of photoionization in the nuclei. NGC 4501 was found to be too faint for study with the IUE spectrographs, while NGC 5005 had an extended ultraviolet light profile.

Ultrasound Controlled‐Release Hydrogel Promotes Diabetic Wound Healing via Neuroimmune Modulation and Synergistic ROS Scavenging

open access: yesAdvanced Science, EarlyView.
This study presents an ultrasound‐responsive hydrogel (MCF@CA) that co‐delivers a neuropeptide (CGRP) and a ROS‐scavenging manganese porphyrin to diabetic wounds. The system restores neuro‐immune communication, reprograms macrophages toward an anti‐inflammatory phenotype, and clears excess ROS, thereby accelerating wound closure and promoting mature ...

Targeted Extracellular Vesicles Deliver Asiaticoside to Inhibit AURKB/DRP1‐Mediated Mitochondrial Fission and Attenuate Hypertrophic Scar Formation

open access: yesAdvanced Science, EarlyView.
Hypertrophic scar formation is driven by excessive mitochondrial fission in wound macrophages, which we discover is governed by a novel AURKB‐DRP1(Ser616) axis. The study develops a targeted therapy using cRGD‐decorated extracellular vesicles to deliver the natural compound Asiaticoside specifically to macrophages.

Ultraviolet spectrophotometry of degenerate stars

open access: yesThe Astrophysical Journal, 1979
Observations of one helium- and three hydrogen-atmosphere degenerates made with the International Ultraviolet Explorer are discussed. Fluxes in the UV give temperatures in good accordance with those determined from the ground and from the ANS satellite data.
