The genoprotective effect of American and Asian ginseng on human lymphocytic DNA was studied. Using the comet assay, aqueous extracts of both types of ginseng were shown to diminish hydrogen peroxide-induced DNA damage. In contrast, and in accordance with traditional Chinese medicine beliefs, addition of the juice from Chinese turnip counteracted the beneficial effect of ginseng. Results showed that incubating ginseng along with turnip juice abolished the DNA protective effect of both American and Asian ginseng. Although the exact mechanism has not been elucidated, the counteracting effect of turnip on ginseng seems unlikely to be mediated by enzymatic action as the effect was seen with boiled as well as unboiled turnip extract.

This bacterium is the causative agent of pneumonia, an acute pulmonary affliction marked by interstitial lung damage. Non-macrolide medications may have potential adverse effects on the developmental trajectory of children, thereby establishing macrolides as the preferred treatment for in pediatric patients.

Predicting the effects of climate change on plant disease is critical for protecting ecosystems and food production. Here, we show how disease pressure responds to short-term weather, historical climate and weather anomalies by compiling a global database (4339 plant-disease populations) of disease prevalence in both agricultural and wild plant systems. We hypothesised that weather and climate would play a larger role in disease in wild versus agricultural plant populations, which the results supported.

Single-nucleotide-resolution genomic maps of O6-methylguanine from the glioblastoma drug temozolomide.

Temozolomide kills cancer cells by forming O6-methylguanine (O6-MeG), which leads to cell cycle arrest and apoptosis. However, O6-MeG repair by O6-methylguanine-DNA methyltransferase (MGMT) contributes to drug resistance. Characterizing genomic profiles of O6-MeG could elucidate how O6-MeG accumulation is influenced by repair, but there are no methods to map genomic locations of O6-MeG.
