Investigation in the Use of Infrared Absorption Spectrophotometry [PDF]

, 1958
Three rather unrelated projects in infrared spectrophotometry were carried out by the writer. First, some effort was expended in trying to find cell windows which were suitably transparent to infrared radiation and yet water insoluable.

Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

Advanced Science, EarlyView.
A ROS‐responsive biomimetic nanoparticle platform co‐delivers DIDS and Mdivi‐1 to protect mitochondria and promote neural repair after intracerebral hemorrhage. By targeting LPAR1/VDAC1‐related mitochondrial dysfunction, the nanotherapy reduces oxidative injury, neuronal apoptosis, and blood‐brain barrier disruption, improving neurological recovery and

Infrared Spectrophotometry as a Means for Identification of Mosquitoes.

Experimental Biology and Medicine, 1953
SummaryCrude aqueous extracts of Culex molestus, Culex quinquefasciatus, and Aedes aegypti adult mosquitoes were identified by infrared spectrophotometry. The most important differences were the relative intensities of the peaks at about 6.95 and 7.2 μ, and the relative depth and shape of the broad band from about 8.6 to 10 μ.

Sonogenetic Control of Engineered Probiotics for the Treatment of MASH by Modulating the Gut‐Liver Axis

Advanced Science, EarlyView.
Researchers developed an engineered probiotic encapsulated in an inulin hydrogel, enabling ultrasound‐triggered intestinal delivery of IL‐22. In MASH model mice, this system remodeled gut microbiota, strengthened the intestinal barrier and reduced portal LPS and hepatic IL‐6.

A Dual‐Functional Nanoplatform Targeting the dsDNA–cGAS Axis to Mitigate Disc Degeneration and Aberrant Innervation

Advanced Science, EarlyView.
RU@PEI‐ZIF integrates dsDNA scavenging with local cGAS inhibition to suppress the dsDNA–cGAS–STING/Netrin‐1 axis in intervertebral disc degeneration. By attenuating nucleus pulposus cell senescence, inflammatory and matrix‐catabolic responses, and pathological sensory innervation, this dual‐functional nanoplatform preserves disc integrity and reduces ...

Targeted Perturbation of Mitochondrial Energy Metabolism via Thermoelectric Nanoflowers for Enhanced Cuproptosis Echoed With Immunotherapy

Advanced Science, EarlyView.
We fabricated a thermoelectric nanomedicine to disrupt the ATP energy supply for the copper transporter ATP7B, thereby enhancing cuproptosis and achieving synergistic immunotherapy for anti‐tumor purposes. The fabricated TBCT NFs can efficiently disrupt the electron transport chain function via superoxide‐induced NADH oxidation, leading to ATP ...

Mitochondria‐Targeting Iron–Carbon Nanozymes Combat Hepatic Ischemia–Reperfusion Injury via the Dual Mechanisms of Respiratory Chain Remodeling and Pyroptosis Inhibition With MRI Monitoring

Advanced Science, EarlyView.
A mitochondrial‐targeted FeCD‐SS31 nanoplatform integrates ROS‐responsive SS31 release with cascade antioxidant Fe3O4/CDs cores to suppress both de novo and existing ROS. By restoring mitochondrial complex integrity and blocking caspase‐1–GSDMD‐N pyroptosis, it reduces neutrophil infiltration and alleviates hepatic ischemia–reperfusion injury, while ...
