Digital clocks: simple Boolean models can quantitatively describe circadian systems.

The gene networks that comprise the circadian clock modulate biological function across a range of scales, from gene expression to performance and adaptive behaviour. The clock functions by generating endogenous rhythms that can be entrained to the external 24-h day-night cycle, enabling organisms to optimally time biochemical processes relative to dawn and dusk. In recent years, computational models based on differential equations have become useful tools for dissecting and quantifying the complex regulatory relationships underlying the clock's oscillatory dynamics.

Human health effects of conjugated linoleic acid from milk and supplements.

The primary purpose of the present review was to determine if the scientific evidence available for potential human health benefits of conjugated linoleic acid (CLA) is sufficient to support health claims on foods based on milk naturally enriched with cis-9, trans-11-CLA (c9, t11-CLA). A search of the scientific literature was conducted and showed that almost all the promising research results that have emerged in relation to cancer, heart health, obesity, diabetes and bone health have been in animal models or in vitro. Most human intervention studies have utilised synthetic CLA supplements, usually a 50:50 blend of c9, t11-CLA and trans-10, cis-12-CLA (t10, c12-CLA).

Meeting Report from the Second "Minimum Information for Biological and Biomedical Investigations" (MIBBI) workshop.

This report summarizes the proceedings of the second workshop of the 'Minimum Information for Biological and Biomedical Investigations' (MIBBI) consortium held on Dec 1-2, 2010 in Rüdesheim, Germany through the sponsorship of the Beilstein-Institute. MIBBI is an umbrella organization uniting communities developing Minimum Information (MI) checklists to standardize the description of data sets, the workflows by which they were generated and the scientific context for the work. This workshop brought together representatives of more than twenty communities to present the status of their MI checklists and plans for future development.

Symposium on "The challenge of translating nutrition research into public health nutrition". Session 4: Challenges facing the food industry in innovating for health. Regulatory challenges and opportunities for food innovation.

The primary role of the extensive and complex modern food legislation is to protect the consumer. Providing a framework for industry and enabling free trade are secondary aims. In the EU the 2006 Regulation on nutrition and health claims made on foods was adopted in December 2006.
