Ambispective study. To determine whether MRI parameters improve the predictive performance of a validated clinical prediction rule used to assess functional outcomes in surgical patients with DCM. Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction
Damian M Herz et al.
Brain : a journal of neurology, 138(Pt 6), 1658-1666 (2015-04-18)
Dopaminergic signalling in the striatum contributes to reinforcement of actions and motivational enhancement of motor vigour. Parkinson's disease leads to progressive dopaminergic denervation of the striatum, impairing the function of cortico-basal ganglia networks. While levodopa therapy alleviates basal ganglia dysfunction

Materials science & engineering. C, Materials for biological applications, 56, 66-73 (2015-08-08)
Advanced engineering of materials for the development of drug delivery devices provides scope for novel and versatile strategies for treatment of various diseases. 'Electrospraying' was used to prepare PLGA microparticles and further encapsulate the drug, metronidazole (Met) within the particles
Myat Noe Hsu et al.
Biomicrofluidics, 9(5), 052601-052601 (2015-04-01)
The poor solubility of many newly discovered drugs has resulted in numerous challenges for the time-controlled release of therapeutics. In this study, an advanced drug delivery platform to encapsulate and deliver hydrophobic drugs, consisting of poly (lactic-co-glycolic acid) (PLGA) nanoparticles
