A Boolean probabilistic model of metabolic adaptation to oxygen in relation to iron homeostasis and oxidative stress

BMC Systems Biology 2011, 5:51doi:10.1186/1752-0509-5-51

Fiona Achcar, Jean-Michel Camadro and Denis Mestivier

Interesting tool, could be helpful to understand better the role of frataxin in the iron homeostasis in Friedreich's ataxia. It could also provide some light to try to explain the great individual differences between genotype - phenotype.

Project title: Characterising gait and upper limb disorder in Friedreich ataxia

Monash University will launch a new study about Friedreich's ataxia

"This project will enable both clinical and quantified gait and upper limb kinematic assessment and may provide a sensitive measure of functional change in FRDA against which the efficacy of novel interventions can be tested down the track".

New Method Delivers Drug to the Brain

Deliver complex drug into the the CNS is a challenge, the CNS is strongly protected by the BBB, and many substances with therapeutic high potential, frataxin, or even gene therapy, are not useful if they can not reach their therapeutic targets. It is very important to have methods to achieve this goal.

New Method Delivers Alzheimer’s Drug to the Brain
ScienceDaily (Apr. 5, 2011) — Oxford University scientists have developed a new method for delivering complex drugs directly to the brain, a necessary step for treating diseases like Alzheimer's, Parkinson's, Motor Neuron Disease and Muscular Dystrophy. read more...
