In the current research work, zein-based polymeric nanocarriers were developed for the delivery of piperine, where the effect of non-ionic surfactants (Tween 80 and Pluronic F-127) on the stability and in vitro drug release characteristics were studied. Physiochemical characterization studies showed that the particle size of blank and drug-loaded surfactant stabilized zein nanoparticles were <200 nm and particles were spherical in shape. FTIR studies confirmed the successful incorporation of piperine within the zein nanoparticle without any alteration in primary structure of zein.

Fucoxanthin (FX) is a carotenoid found in marine environments with a range of nutritional functions. However, its application in the food industry has been restricted by its vulnerability to deterioration and absorption challenges. This study employed zein to develop hydrophilic colloids to enhance the thermal processing adaptability, gastrointestinal digestive stability, and oral bioavailability of FX.

This study investigates the immobilization of cyanobacterial photosystem I (PSI) from sp. PCC 6803 onto fluorine-doped tin oxide (FTO) conducting glass plates to create photoelectrodes for biohybrid solar cells. The fabrication of these PSI-FTO photoelectrodes is based on two immobilization processes: rapid electrodeposition driven by an external electric field and slower adsorption during solvent evaporation, both influenced by gravitational sedimentation.

Article Synopsis
- A study compared the proteomes of calcium oxalate monohydrate kidney stones in cats and humans, revealing substantial similarities but limited analysis due to a lack of cat urine proteomic data.
- Urine proteome data from 7 healthy cats was gathered and compared to human urine and cat calcium oxalate stone matrices to identify shared enrichment patterns.
- The findings indicated that cat urine proteins showed distribution similarities to human urine, while differences in cat struvite stone matrices suggest distinct mechanisms of stone formation involving both protein interactions and crystal aggregation.
