Three botulinum neurotoxin type A (BoNT/A) products, incobotulinumtoxinA, onabotulinumtoxinA, and abobotulinumtoxinA, all manufactured by different methods, are employed in clinical practice. Comparing the three BoNT/A products is difficult because their concentrations and volumes differ and the precise dose equivalence ratio is not known. We aimed to(More)
OBJECTIVE Transcranial direct current stimulation (tDCS) induces changes in cortical excitability and improves hand-motor function in chronic stroke. These effects depend on polarity, duration of stimulation and current intensity applied. Towards evaluating the therapeutic potential of tDCS in acute stroke, we investigated tDCS-effects on cerebral blood(More)
TBC1D10C is a protein previously demonstrated to bind and inhibit Ras and Calcineurin. In cardiomyocytes, also CaMKII is inhibited and all three targeted enzymes are known to promote maladaptive cardiomyocyte hypertrophy. Here, in accordance with lack of Calcineurin inhibition in vivo, we did not observe a relevant anti-hypertrophic effect despite(More)
Tetanus neurotoxin (TeNT) enhances activity of motoneurons by blocking spinal inhibitory interneurons. Based on this pathomechanism, we propose that low-dosage intramuscular injections of TeNT could serve as a specific treatment for central paretic muscles. However in vivo TeNT research is restricted because of the fear of triggering widespread muscle(More)
The highly potent Botulinum neurotoxins (BoNT) are successful drugs to treat neuromuscular disorders. Efforts are being made to further reduce the injected BoNT dose and to lengthen the interval between treatments. Detailed knowledge of the BoNT structure-activity relationship (SAR) allows combining the best features of the different BoNT serotypes. Of all(More)
INTRODUCTION To test the hypothesis that the efficacy of botulinum toxin depends on the activity of the neuromuscular junction, we developed an in vivo paradigm to determine the degree and duration of low-dose botulinum toxin-induced focal paresis in mice. METHODS We combined an automated wheel-running paradigm with low-dose botulinum toxin injections(More)
Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is one of the rarest and most serious headache disorders. Cases of symptomatic SUNCT syndromes are reported, which demonstrate that brain imaging is very important for diagnosis. In this study, we describe the first case of secondary SUNCT syndrome caused by a(More)
Inappropriate insulin secretion and biosynthesis are hallmarks of beta cell dysfunction and contribute to the progression from a prediabetic state to overt diabetes mellitus. During the prediabetic state, beta cells are exposed to elevated levels of proinflammatory cytokines. In the present study the effect of these cytokines and mitogen-activated protein(More)
