Summary: In Alzheimer's disease, the formation of amyloid beta aggregates and neurofibrillary tangles is closely associated with neurodegeneration in the brain. To mitigate the toxicity of amyloid beta fibrils, a vitamin E derivative called TPGS was conjugated with a dendrimer called PAMAM to synthesize TPGS-PAMAM. Piperine, a neuroprotective agent, was then entrapped in TPGS-PAMAM to prepare PIP-TPGS-PAMAM. The synthesized dendrimer conjugate showed promising effects in reducing neurotoxicity and improving cognitive functions in AD mouse models.

Summary: The study found that color differences in disperse dyes are mainly caused by changes in solubilities and affinities due to ester groups, rather than changes in light absorbance abilities and melting points. Unesterified dyes showed a significant reduction in dye sorption in polyethylene terephthalate compared to completely esterified dyes.

Summary: By using a bioreducible polymer as a nonviral vector and introducing enzyme-cleavable linkers and dipeptides, researchers achieved high transfection efficiency and low cytotoxicity in overexpressing cathepsin B cells. This study suggests that a combination of enzyme- and reduction-responsive linkers can improve the drawbacks associated with nonviral vectors in gene medicine.
