BACKGROUND Recent research in humans and rodents has explored the use of deep brain stimulation (DBS) of the ventral capsule/ventral striatum (VS) as a possible treatment for drug addiction. However, the optimum electrode placement and optimum DBS parameters have not been thoroughly studied. Here we varied stimulation sites and frequencies to determine whether DBS of the VS could facilitate the...

BACKGROUND The use of simplified methods for viral load determination could greatly increase access to treatment monitoring of HIV patients in resource-limited countries. OBJECTIVE The aim of the present study was to optimize and evaluate the performance of the Roche COBAS Taqman assay in HIV-RNA quantification from dried blood spots (DBS) and dried plasma spots (DPS). STUDY DESIGN EDTA blo...

Digitalization does fundamentally impact firms’ strategy development. With the fusion of IT and business strategy, Digital Business Strategy (DBS) creates the foundation for digital business models [1]. In this paper, we develop a DBS framework, based on a structured review of 21 industry reports. From this analysis, we yield 8 generic dimensions with a total of 40 critical success factors (CSF...

Deep brain stimulation (DBS), a reversible and adjustable treatment for neurological and psychiatric refractory disorders, consists in delivering electrical currents to neuronal populations located in subcortical structures. The targets of DBS are spatially restricted, but connect to many parts of the brain, including the cortex, which might explain the observed clinical benefits in terms of sy...

Deep Brain Stimulation (DBS) is a promising treatment for neurological and psychiatric disorders. The mechanism of action and the effects of electrical fields administered to the brain by means of an electrode remain to be elucidated. The effects of DBS have been investigated primarily by electrophysiological and neurochemical studies, which lack the ability to investigate DBS-related responses...

abstract introduction: it is demonstrated that the degree of clinical improvement in parkinson's disease (pd) achieved by deep brain stimulation (dbs) is largely dependent on the accuracy of lead placement. in addition, individual variability in the situation of subthalamic nucleus (stn) is responsible for spatial inter-individual fluctuations of the real patient's target. objective: our study ...

Although there is general consensus that deep brain stimulation (DBS) yields substantial clinical benefit in patients with Parkinson's disease (PD), the therapeutic mechanism of DBS remains a matter of debate. Recent studies demonstrate that DBS targeting the globus pallidus internus (GPi-DBS) suppresses pathological oscillations in firing rate and between-cell spike synchrony in the vicinity o...

Deep brain stimulation of the subthalamic nucleus (STN-DBS) in patients with Parkinson's disease (PD) affects speech inconsistently. Recently, stimulation of the caudal zona incerta (cZi-DBS) has shown superior motor outcomes for PD patients, but effects on speech have not been systematically investigated. The aim of this study was to compare the effects of cZi-DBS and STN-DBS on voice intensit...

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a widely used treatment for the motor symptoms of Parkinson's disease (PD). DBS or pharmacological treatment is believed to modulate the tendency to, or reverse, impulse control disorders. Several brain areas involved in impulsivity and reward valuation, such as the prefrontal cortex and striatum, are linked to the STN, and activi...

Deep brain stimulation (DBS) has successfully advanced our treatment options for putative therapy-resistant neuropsychiatric diseases. Building on this strong foundation, more and more mental disorders in the stadium of therapy-resistance are considered as possible indications for DBS. Especially, schizophrenia with its associated severe and difficult to treat symptoms is gaining attention. Thi...
