Hydrogels Constructed from Engineered Proteins.

Due to their various potential biomedical applications, hydrogels based on engineered proteins have attracted considerable interest. Benefitting from significant progress in recombinant DNA technology and protein engineering/design techniques, the field of protein hydrogels has made amazing progress. The latest progress of hydrogels constructed from engineered recombinant proteins are presented, mainly focused on biorecognition-driven physical hydrogels as well as chemically crosslinked hydrogels.

Augmentative therapies do not potentiate the antidepressant-like effects of deep brain stimulation in rats.

Background: Clinical trials have shown promising results with the use of subcallosal cingulate gyrus deep brain stimulation (DBS) for treatment-resistant depression. However, strategies to manage patients who do not respond to this therapy have not been explored in detail. In rats, DBS in the ventromedial prefrontal cortex (vmPFC) induces a significant antidepressant-like response in the forced swim test (FST).
