The Occurrence of an Eye and of a Tooth Abnormality in a Line of Albino Rats

open access: greenThe American Naturalist, 1925
IT has been demonstrated many times, in those forms whose eggs are fertilized outside the body cavity of the female, that deviations from the normal oxygen supply are capable of producing metabolic changes in the developing embryo. Since such changes result in visible disturbances of the growth of certain organs, one is led to believe that their effect

Volumetric Engineered 3D Drug Reservoir Against Diabetic Implant Infection via Cuproptosis‐Like Bacterial Death and Hunger‐Triggered Maintenance of Mitochondrial Integrity

open access: yesAdvanced Science, EarlyView.
This study provides a volumetric engineered 3D drug reservoir to combat diabetic implant infection. Cu‐doped quantum dots induce cuproptosis‐like bacterial death via metabolic collapse, while glucose oxidase triggers hunger‐triggered mitochondrial protection in host cells.
