Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Black rice (BR) extract contains several functional food bioactive components that are health-promoting. This study assessed the multifunctional bioactivities of various BR extracts (methanol, ethanol, acetone, and aqueous). These BR extracts revealed significant antioxidant and antibacterial activity against various bacterial strains. Acetone extract exhibited high cytotoxicity against gastric adenocarcinoma cells (AGS), while ethanol extract was cytotoxic against pancreatic cancer cells (PANC-1). Moreover, the acetone extract induced 33.6 % and 16.5 % apoptosis in PANC-1 and AGS cells, respectively. Acetone extract showed significant anti-inflammatory action, reducing 76 % production of nitric oxide in the RAW 264.7 (murine macrophage). Furthermore, all BR extracts inhibited PANC-1 and AGS migration and promoted RAW 264.7 migration. Field emission scanning electron microscope, Fourier-transform infrared spectroscopy, and X-ray diffraction analysis of the BR-polyhydroxybutyrate composite revealed successful deposition for BR extracts. This study highlights the potential of BR extracts to develop multifunctional activity-based strips for rapid wound healing.
