Lifestyle factors, such as food choices and exposure to chemicals, can alter DNA methylation and lead to changes in gene activity. Two such exposures with pharmacologically active components are coffee and tea consumption. Both coffee and tea has been suggested to play an important role in modulating disease-risk in humans by suppressing tumour progression, decreasing inflammation and influencing estrogen metabolism. These mechanisms may be mediated by changes in DNA methylation.To investigate if DNA methylation in blood is associated with coffee and tea consumption we performed a genome-wide DNA methylation study for coffee and tea consumption in four European cohorts (N = 3,096)...

In a 1986 article (Am J Epidemiol. 1986;124(6):903-915), Keys et al. described and discussed 15-year findings from 15 cohorts of the Seven Countries Study (SCS), the first systematic study of diet, risk characteristics, disease-specific death rates, and their ecologic and individual associations both among and within whole populations of working men in regions with contrasting traditional diets. The SCS findings included 30-fold cohort differences in rates of death from coronary heart disease and 3-fold differences in rates of death from all causes, along with strong ecologic associations among diet, risk factors, and disease rates...

SNP arrays are enabling tools for high-resolution studies of the genetic basis of complex traits in farmed and wild animals. Oysters are of critical importance in many regions from both an ecological and economic perspective, and oyster aquaculture forms a key component of global food security. The aim of our study was to design a combined-species medium density SNP array for Pacific oyster (C. gigas) and European flat oyster (O. edulis), and to test the performance of this array on farmed and wild populations from multiple locations, with a focus on European populations...

REVIEW
Frédéric Guichard
Metacommunity theory has provided many insights into the general problem of local versus regional control of species diversity and relative abundance. The metacommunity framework has been extended from competitive interactions to whole food webs that can be described as spatial networks of interaction networks. Trophic metacommunity theory greatly contributed to resolving the community complexity-stability debate by predicting its dependence on the regional spatial context. The meta-ecosystem framework has since been suggested as a useful simplification of complex ecosystems to apply this spatial context to spatial flows of both individuals and matter...

BACKGROUND: Inflammation within the central nervous system (CNS) is frequently comorbid with anxiety. Importantly, the pro-inflammatory cytokine most commonly associated with anxiety is IL-1β. The bioavailability and activity of IL-1β are regulated by caspase-1-dependent proteolysis vis-a-vis the inflammasome. Thus, interventions regulating the activation or activity of caspase-1 should reduce anxiety especially in states that foster IL-1β maturation. METHODS: Male C57BL/6j, C57BL/6j mice treated with the capase-1 inhibitor biotin-YVAD-cmk, caspase-1 knockout (KO) mice and IL-1R1 KO mice were fasted for 24h or allowed ad libitum access to food...

Mercury (Hg) in fish has attracted public attention for decades, and methylmercury (MeHg) is the predominant form in fish. However, the in vivo MeHg demethylation and its influence on Hg status in fish have not been well addressed. The present study investigated the in vivo demethylation process in a marine fish (black seabream, Acanthopagrus schlegeli) under dietary MeHg exposure and depuration, and quantified the biotransformation and inter-organ transportation of MeHg by developing a physiologically based pharmacokinetic (PBPK) model...

INTRODUCTION: Diet therapy is one of the corner stone's in the management of diabetes. Keeping the blood sugar level as close to normal is the main focus of dietary management of diabetes. A typical Indian meal is largely composed of Carbohydrates (CHO). Consumption of staple cereals, forms the major source of CHO in the Indian diet. However, CHO metabolism is seen to be completely deranged in a person with type 2 diabetes. It is necessary to select the cereal which has lower postprandial glycaemic impact for subjects with compromised metabolic status...
