Adverse effects of polystyrene nanoplastic and its binary mixtures with nonylphenol on zebrafish nervous system: From oxidative stress to impaired neurotransmitter system.

Micro(nano)plastics generally co-exist with other chemicals in the environment, resulting in inevitable interaction and combined toxic effects on biota. Nevertheless, little is known regarding the interaction of nanoplastics (NPs) with other co-occurring insults. Hereby, we investigated single and combined effects of chronic exposure (45 days) to polystyrene nanoplastic particulates (PS-NPs) and nonylphenol (4-NP) on zebrafish nervous system.

Phosphonate analog of 2-oxoglutarate regulates glutamate-glutamine homeostasis and counteracts amyloid beta induced learning and memory deficits in rats.

Background: Metabolic alteration is a mainstream concept underlying the cognitive decline in neurodegenerative disorders including Alzheimer's disease (AD). Mitochondrial enzyme α-ketoglutarate dehydrogenase complex (α-KGDHC) seems to play a dual-edged sword role in cytotoxic insult. Here, using succinyl phosphonate (SP), a specific α-KGDHC inhibitor, we aimed to examine its potential action on AD progression.

Folic acid conjugated bovine serum albumin: An efficient smart and tumor targeted biomacromolecule for inhibition folate receptor positive cancer cells.

This work described a folic acid conjugated delivery of chrysin-loaded bovine serum albumin nanoparticles, which could overcome the nonspecific targeting disadvantage. Chrysin (5, 7-dihydroxyflavone) is a natural flavonoid which have some significant biological effects on the processes of chemical defense. Chrysin loaded bovine serum albumin nanoparticles (Chrysin-BSA NPs) were synthesized by a simple desolvation procedure.

Production of biological nanoparticles from bovine serum albumin as controlled release carrier for curcumin delivery.

This study described a curcumin (CUR) loaded bovine serum albumin nanoparticles (BSA@CUR NPs), which could solubilize the poorly water-soluble drug and increase the therapeutic efficacy of the drug. BSA@CUR NPs were synthesized by a simple coacervation procedure. The resultant BSA@CUR NPs showed a spherical shape, with a diameter of 92.
