Beetroot supplement raises nitric oxide markers in triathletes after one week

A randomized cross-over pilot study in 10 amateur male triathletes found that a beetroot-based multi-ingredient nitrate supplement increased nitric oxide-related and redox biomarkers over 7 days without evidence of lipid oxidative damage. The supplement was generally well tolerated, but the study did not measure whether these biochemical changes improved performance or recovery.

Lab study shows cigarette smoke damaged lung cells more than e-cigarette vapor

Researchers found that cigarette smoke extract disrupted the lung cell barrier, increased IL-6 inflammation, and caused DNA damage in Calu-3 cells, while e-cigarette vapor extract showed no significant adverse effects on these measures under the study conditions. The authors caution that these were in vitro findings using liquid extracts and unflavored e-liquid, so they do not directly predict long-term human health outcomes.

Targeted diet helps reprogram aggressive neuroblastoma in mice

Researchers highlighted how an arginine- and proline-restricted diet combined with eflornithine reprogrammed MYCN-driven neuroblastoma in mice, pushing tumor cells out of the cell cycle and toward differentiation. The commentary argues that this metabolism-to-translation link could open a new path for testing targeted dietary strategies alongside cancer drugs in future clinical studies.
