PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Neural Mechanisms and Pathways in Craniofacial Pain [PDF]

open access: yesCanadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1999
Many free nerve endings of small-diameter afferents (A-delta or C nerve fibres) respond to craniofacial noxious stimuli and a number of neurochemicals are involved in their activation or sensitization. The small-diameter nociceptive afferents project to the trigeminal (V) brainstem complex where they can excite nociceptive neurones that have been ...

Mimicking natural neural encoding through retinal electrostimulation

open access: yes, 2017
Retinal neuroprostheses or `bionic eyes', aim to restore patterned vision to those with vision loss by electrically stimulating the remaining neurons in the degenerate retina.

Neural responses to others' pain vary with psychopathic traits in healthy adult males. [PDF]

open access: yes, 2015
Disrupted empathic processing is a core feature of psychopathy. Neuroimaging data have suggested that individuals with high levels of psychopathic traits show atypical responses to others' pain in a network of brain regions typically recruited during ...

Mechanisms of electrical vasoconstriction

open access: yesJournal of NeuroEngineering and Rehabilitation, 2018
Background Electrical vasoconstriction is a promising approach to control blood pressure or restrict bleeding in non-compressible wounds. We explore the neural and non-neural pathways of electrical vasoconstriction in-vivo.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The performance of approximating ordinary differential equations by neural nets

open access: yes, 2010
The dynamics of many systems are described by ordinary differential equations (ODE). Solving ODEs with standard methods (i.e. numerical integration) needs a high amount of computing time but only a small amount of storage memory. For some applications, e.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
