A sensitive and selective method is needed to analyse in situ produced vitamin B12 in plant-based materials, potential new dietary sources of vitamin B12. A UHPLC/UV method was developed and validated for the determination of human active vitamin B12 in cell extracts of Propionibacterium freudenreichii subsp. shermanii and after immunoaffinity purification in extracts of cereal matrices ferment...

BACKGROUND Poor micronutrient status is reported among adolescents across Europe and USA. This may be related to the well-documented decline in the regular consumption of breakfast by this group. The regular consumption of a breakfast cereal offers a possible means to improve micronutrient status; fortified cereal is likely to have enhanced benefit. A study was conducted to determine the effica...

BACKGROUND Conflicting results from vitamin E intervention studies suggest supplemental vitamin E malabsorption. OBJECTIVE We compared vitamin E bioavailability from a supplement with that from a fortified breakfast cereal. DESIGN Vitamin E bioavailability was evaluated by using deuterium-labeled all-rac-alpha-tocopherol in three 4-d trials (2 wk apart). Five fasting subjects sequentially c...

Soil carbon changes were modelled over 30 years with the focus on cereal crops, since leys are often managed similarly in organic and conventional agriculture. Other crops were not considered due to difficulties in large-scale cropping of oilseed rape and potatoes organically because of pest problems. Four scenarios were used: 0%, 8% (current), 20% and 100% organic cereal production. Conversion...

Recent data on breakfast consumption among Australian children are limited. This study examined the impact of breakfast skipping and breakfast type (cereal or non-cereal) on nutrient intakes, likelihood of meeting nutrient targets and anthropometric measures. A secondary analysis of two 24-h recall data from the 2007 Australian National Children's Nutrition and Physical Activity Survey was cond...

BACKGROUND This study compared the effects of ingesting cereal and nonfat milk (Cereal) and a carbohydrate-electrolyte sports drink (Drink) immediately following endurance exercise on muscle glycogen synthesis and the phosphorylation state of proteins controlling protein synthesis: Akt, mTOR, rpS6 and eIF4E. METHODS Trained cyclists or triathletes (8 male: 28.0 +/- 1.6 yrs, 1.8 +/- 0.0 m, 75....

This study examines whether readers of the paper and online versions of a national newspaper acquire different perceptions of the importance of political issues. Using data from a weeklong experiment in which subjects either read the print version of the New York Times, the online version of that paper, or received no special exposure, this study finds evidence that people exposed to the Times ...

Online news comments are often confronted with issues of civility and inclusivity, which are sometimes pegged to the anonymity afforded to contributors in those spaces. In this work we study one form of anonymity in online comments that manifests as users changing their display name when they write a given comment. We undertake a predominantly quantitative analysis of how display names are chan...
