New (fluorescent) light on the fight-or-flight response as the Zaccolo Group (DPAG) has their paper published in the journal Nature Communications.

The Zaccolo group, led by Professor Manuela Zaccolo, has had their paper “FRET biosensor uncovers cAMP nano-domains at β-adrenergic targets that dictate precise tuning of cardiac contractility” published in Nature Communications. The research published in this article was funded by the British Heart Foundation and the Oxford BHF CRE

The primordial fight-or-flight response is a physiological reaction to stress. Under stress, the hormones adrenaline and noradrenaline trigger the production of a small signalling molecule, cAMP, that acts inside the cell to activate the appropriate reaction to the stressful situation. The Zaccolo Group has developed a method, based on the use of fluorescent light, which allows them to see cAMP inside living cells.

Language learning difficulties in children linked to brain differences

A new study using MRI has revealed structural brain changes in children with developmental language disorder (DLD), a common but under-recognised difficulty in language learning. Children with DLD aged 10-15 showed reduced levels of myelin in areas of the brain associated with speaking and listening to others, and areas involved in learning new skills. This finding is a significant advance in our understanding of DLD and these brain differences may explain the poorer language outcomes in this group.

Night-time blood pressure assessment is found to be important in diagnosing hypertension

Around 15% of people aged 40-75 may have a form of undiagnosed high blood pressure (hypertension) that occurs only at night-time. Because they do not know about this, and therefore are not being treated for it, they are at a higher risk of cardiovascular disease such as stroke, heart failure, and even death, suggests new research from the University of Oxford published in the British Journal of General Practice.
