Background: β-caryophyllene (BCP) is a naturally occurring bicyclic sesquiterpene extracted from various plants, and widely used as a medicinal agent for various diseases. During hepatocellular carcinoma (HCC) development, cancer cells generally exhibit increased cell proliferation due to mutations or aberrant expression of key regulatory genes. The current study determines the cytotoxic effects of BCP alone or in combination with doxorubicin (DOX) and cisplatin (DDP) on HCC cells, and elucidates the underlying mechanism of BCP to exert its anticancer activities.

Circadian rhythms, which regulate essential physiological and behavioral processes, are crucial for maintaining overall health and well-being. However, disruptions to these rhythms, particularly due to trans-meridian travel and shift work, can lead to significant health issues, including jet lag, metabolic imbalances, and neuropsychiatric disorders. In this systematic review, conducted in line with Preferred Reporting Items for Systematic Reviews and Metanalysis (PRISMA) 2020 guidelines, we explore the effectiveness of various interventions aimed at realigning circadian rhythms disrupted by such factors.
