BACKGROUND Milk as a common diet is recommended by many guidelines, but the results on the association of milk consumption with the risk of cardiovascular disease (CVD) or cancer were contradictory. Moreover, evidence regarding milk consumption and mortality risk in Chinese is scarce. OBJECTIVE We examined the associations of milk consumption with the risk of all-cause, CVD and cancer mortality in a low milk consumption population using data from the Guangzhou Biobank Cohort Study. DESIGN 18,214 participants aged 50+ years without CVD history at baseline (2003-6) were included. Causes of death were identified through record linkage. check details Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS Of the 18,214 participants, 12,670 (69.6%) did not consume milk, 2669 (14.7%) had moderate (1-3 portions/week; 1 portion = 250 ml) and 2875 (15.8%) had high (3+ portions/week) consumption. During an average follow-up of 11.5 (standard deviation = 2.3) years, 2697 deaths occurred, including 917 CVD and 1029 cancer deaths. Compared with no consumption, the adjusted HR (95% CIs) of all-cause, CVD, ischemic heart disease (IHD) and stroke mortality for moderate milk consumption was 0.92 (0.81-1.04), 0.72 (0.57-0.92), 0.57 (0.38-0.85) and 0.77 (0.63-0.94), respectively. High consumption was associated with a higher risk of total cancer and esophagus cancer mortality, with the adjusted HR (95% CIs) being 1.33 (1.12-1.57) and 3.20 (1.21-8.43) respectively. No significant association of high consumption with lung cancer, liver cancer, gastrointestinal cancer, or colorectal and anal cancer was found. CONCLUSIONS In our sample of Chinese with much lower milk consumption than those in the West, compared with no consumption, moderate milk consumption showed a lower risk of CVD mortality, but high milk consumption showed a higher risk of total cancer mortality. Further studies are warranted to verify the differential effects of milk on CVD and cancer. BACKGROUND & AIMS Cancer is the second most common chronic disease and cause of death in the United States. Our aim was to evaluate the associations of sedentary behavior and nutrient intakes with total and cancer-specific mortality among US cancer survivors. METHODS Data from 2371 cancer survivors collected by the US National Health and Nutrition Examination Survey between 1999 and 2014 were linked to the US mortality registry. Multivariable adjusted Cox proportional hazard models were used to estimate the hazard ratios (HR) and 95% confidence intervals (CI) for all-cause and cancer-specific mortality associated with sedentary time and nutrient intakes. The interaction between time spent on sedentary activities and nutrient intake was evaluated on additive and multiplicative scales. RESULTS During a median observational period of 5.7 years, 532 total deaths occurred among cancer survivors, of which 180 were cancer-specific. A monotonic increasing linear relationship between time spent sitting and all-cause mortality was observed (HR = 1.15, 95% CI = 1.03, 1.28 per one standard deviation increment). The highest versus the lowest tertiles of intakes of dietary fiber, carotene, niacin, thiamine, riboflavin, vitamin B6, vitamin B12, and vitamin C were inversely associated with all-cause and cancer-specific mortality (HRs = 0.48 to 0.75). The inverse associations with all-cause mortality were more pronounced for combinations of low sedentary behaviour and high intakes of dietary fiber, carotenoids, vitamin B12, and vitamin C. CONCLUSION Our findings support recommendations for cancer survivors to reduce time spent sedentary and to follow a balanced diet with adequate intakes of dietary fiber and micronutrients. Among the family of mycotoxins of deoxynivalenol (DON) detected in nature, high proportions of 15-acetyldeoxynivalenol (15ADON) co-occur with the prototype DON and increase the combined exposure and synergistic health risks. The current study aimed to explore the mechanisms underlying the toxicity of 15ADON and compare them with those of DON. As the natural flavonoid compound quercetin (QUE) possesses antioxidant properties, we also aimed to determine the antioxidant effects of QUE on the tested mycotoxins. First, the global metabolomics approach was applied and showed that the metabolites produced from 15ADON or DON were almost identical, while QUE reversed the changes in the levels of key metabolites. Specifically, both DON and 15ADON activated the cell apoptosis pathway mediated by p38 and JNK, but inhibited the cell survival pathway mediated by ERK1/2 in GES-1 cells. Simultaneously, 15ADON induced FOXO3a nuclear translocation, similar to the results described for DON in our recent report. Furthermore, the addition of QUE appeared to counteract the detrimental effects of 15ADON and DON. We observed the effects of QUE treatment on mutant yeast strains with defects in their antioxidant system. More interestingly, QUE also substantially restored the increased ROS levels and the inhibited the growth rate following exposure to the mycotoxins DON and 15ADON. The data reported here support the hypothesis that QUE rescues the toxic effects of DON or 15ADON due to the similar mechanisms of DON and 15ADON toxicity. Deoxynivalenol (DON), a type B trichothecene mycotoxin mainly affects the health status of pigs and reduced their growth. This study aimed to determine the effects of PI3K/Akt/mTOR pathway on DON-induced autophagy of piglet hippocampal nerve cells (PHNCs), and the relationship between autophagy and apoptosis. The effects of DON on autophagy of PHNCs were examined by cell morphology, cell viability, apoptosis rate, electron microscopy, transient transfection of GFP-LC3 plasmid, immunofluorescence and expression of autophagy-related genes and proteins. The relationship between autophagy and cell apoptosis was analyzed by western blotting, CCK-8 and flow cytometry. The results indicated that, DON inhibited the proliferation of PHNCs and significantly changed cell morphology, and induced apoptosis and autophagy. The expression levels of LC3 protein and gene increased, while the expression levels of PI3K/Akt/mTOR pathway-related genes and proteins decreased, when the concentration of DON increased. Activation of autophagy significantly increased cell viability, reduced apoptosis rate, inhibits autophagy significantly, reduced cell activity and increased apoptosis rate.
