Harmonization of blood-based indicators of iron status: making the hard work matter
assay bias clinical bioindicator harmonization imprecision iron status reference material reference method standardization
2018/11/21
Blood-based indicators that are used in the assessment of iron status are assumed to be accurate. In practice, inaccuracies in these measurements exist and stem from bias and variability. For example,...
You can see that from here:New telescope attachment allows ground-based observations of new worlds to rival those from space（图）
New telescope attachment ground-based observations new worlds space
2017/10/25
A new, low-cost attachment to telescopes allows previously unachievable precision in ground-based observations of exoplanets -- planets beyond our solar system. With the new attachment, ground-based t...
Testing the direction of effects between child body composition and restrictive feeding practices: results from a population-based cohort
feeding feeding behavior parenting restriction childhood obesity BMI body composition longitudinal studies children general population
2018/11/16
Background: Parental restrictive feeding (i.e., limiting food intake of children) has been linked to childhood overweight. However, the directionality of the causal pathway remains unknown.
2017第六届平行和云生物信息学与生物医学国际研讨会（6th International Workshop on Parallel and Cloud-based Bioinformatics and Biomedicine ）

Differences in genetic and environmental variation in adult BMI by sex, age, time period, and region: an individual-based pooled analysis of 40 twin cohorts
BMI adults genetics twins international comparisons
2018/11/15
Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood.
