Enhanced drug release through nitrendipine/hydroxypropyl methylcellulose solid dispersion via supercritical antisolvent technique.

The poor water solubility of nitrendipine (NT) results in low oral bioavailability, which hinders its practical application. Hydroxypropyl methylcellulose (HPMC) is a prominent drug carrier that has been applied in the biomedical field due to its significant characteristics, such as large surface area, biocompatibility and biodegradability. In this study, an efficient drug delivery system based on the preparation of NT/HPMC solid dispersion using supercritical antisolvent (SAS) technology was proposed.

Elucidating the effect of biofertilizers on bacterial diversity in maize rhizosphere soil.

This study was conducted to investigate the effect of biofertilizers on the structure and diversity of the rhizosphere bacterial community of maize. Different biofertilizers were applied to maize. The physical and chemical properties of rhizosphere soil samples were analyzed and the rhizosphere bacteria were analyzed by 16S amplicon sequencing.
