Validation of an In Vitro Digestive System

submitted by: KopfBolanz
The digestive process transforms nutrients and bioactive compounds contained in food to physiologically active compounds. In vitro digestion systems have proven to be powerful tools for understanding and monitoring the complex transformation processes that take place during digestion. Moreover, the investigation of the physiological effects of certain nutrients demands an in vitro digestive process that is close to human physiology. In this study, human digestion was simulated with a 3-step...

Preparation of broccoli extracts for biological studies

submitted by: tkaragiannis
In this video, Katherine Ververis (Epigenomic Medicine, Baker IDI Heart and Diabetes Institute), demonstrates how to extract nutrients from the florets of broccoli. We investigate the effects of broccoli extract on the viability on human erythroleukemic K562 cells. Broccoli evolved ~2000 years ago from a wild cabbage plant in Europe and since the Roman Empire it has been considered a uniquely valuable food among Italians. The word broccoli, is derived from the Italian plural of broccolo,...

Multisector Intervention to Accelerate Reductions in Child Stunting: An Observational Study from 9 Sub-Saharan African Countries

submitted by: Alison Rose
Background: In sub-Saharan Africa, ~40% of children <5 y old are stunted, with levels that have remained largely unchanged over the past 2 decades. Although the complex determinants of undernutrition are well recognized, few studies have evaluated strategies that combine nutrition-specific, health-based approaches with food system– and livelihood-based interventions. Objective: We examined changes in childhood stunting and its determinants after 3 y of exposure to an integrated,...

Green Revolution: Biomass

submitted by: nsf
Explore how different types of biomass can be used to produce fuel. One researcher is building reactors to grow algae used to create biofuel. Another studies how leafcutter ant colonies break down biomass in order to solve a different biofuel problem: conversion of cellulose in plants to a fermentable sugar used to make ethanol. Finally, an engineer shows us how his lab uses chemistry and heat to turn sawmill waste into bio-oil and gasoline.

Video tip of the week: Variation Data from Ensembl

submitted by: OpenHelix
For more information about this resource see our blog post at URL http://blog.openhelix.eu/?p=10091. In today's tip I am going redo a movie originally done by Ensembl on SNP information in Ensembl, but I will use the updated Ensembl release 64.

Re-evaluating The Hubbert Curve And The Global Petroleum Revolution: A New Era - Details

submitted by: RASEIBoulder
Summary: Why have the predicted global oil and natural gas shortages and demise of civilization by 2010 related to these vanishing supplies not occurred? The static view has created a pessimistic outlook based on historical perspective such as the Hubbert curve analysis which results in the inescapable and inevitable depletion that will result in catastrophic consequences for civilization. A new paradigm, a dynamic or petroleum system view demonstrates a different and more optimistic...
