Neural Basis of Internal Attention in Adults with Pure and Comorbid ADHD

Farnaz Delavari

Objective: To examine whether putatively atypical neuronal activity during internal attention in ADHD yields insights into processes underlying emotion dysregulation. Methods: We used a word processing paradigm to assess neural activations in adults with A ...

Dopamine and Methamphetamine Differentially Affect Electron Transport Chain Complexes and Parkin in Rat Striatum: New Insight into Methamphetamine Neurotoxicity

Bernard Schneider

Methamphetamine (METH) is a highly abused psychostimulant that is neurotoxic to dopaminergic (DAergic) nerve terminals in the striatum and increases the risk of developing Parkinson's disease (PD). In vivo, METH-mediated DA release, followed by DA-mediated ...

Cell-type-specific nicotinic input disinhibits mouse barrel cortex during active sensing

Carl Petersen, Sylvain Crochet, Célia Roxane Gasselin

Fast synaptic transmission relies upon the activation of ionotropic receptors by neurotransmitter release to evoke postsynaptic potentials. Glutamate and GABA play dominant roles in driving highly dynamic activity in synaptically connected neuronal circuit ...

Predicting Modafinil-Treatment Response in Poststroke Fatigue Using Brain Morphometry and Functional Connectivity

Bénédicte Marie Maréchal

Background and Purpose- Poststroke fatigue affects a large proportion of stroke survivors and is associated with a poor quality of life. In a recent trial, modafinil was shown to be an effective agent in reducing poststroke fatigue; however, not all patien ...

Identification of Isomeric Ephedrines by Cold Ion UV Spectroscopy: Toward Practical Implementation

Oleg Boyarkine, Vladimir Kopysov

Ephedrine and pseudoephedrine are stimulant drugs whose use is prohibited in athletic competition by the World Anti Doping Agency (WADA) at very different threshold doping violation concentrations. We use a recently developed universal approach that integr ...

Photosensitizing and Inhibitory Effects of Ozonated Dissolved Organic Matter on Triplet-Induced Contaminant Transformation

Urs von Gunten

Dissolved organic matter (DOM) is both a promoter and an inhibitor of triplet-induced organic contaminant oxidation. This dual role was systematically investigated through photochemical experiments with three types of DOM of terrestrial and aquatic origins ...

A streamlined search technology for identification of synergistic drug combinations

Paul Joseph Dyson, Hubert van den Bergh, Patrycja Nowak-Sliwinska, Andrea Brett Gasser

A major key to improvement of cancer therapy is the combination of drugs. Mixing drugs that already exist on the market may offer an attractive alternative. Here we report on a new model-based streamlined feedback system control (s-FSC) method, based on a ...

Intestinal FXR agonism promotes adipose tissue browning and reduces obesity and insulin resistance

Kristina Schoonjans, Alessia Perino

The systemic expression of the bile acid (BA) sensor farnesoid X receptor (FXR) has led to promising new therapies targeting cholesterol metabolism, triglyceride production, hepatic steatosis and biliary cholestasis. In contrast to systemic therapy, bile a ...

Small effects of smoking on visual spatiotemporal processing

Michael Herzog

Nicotine is an important stimulant that is involved in modulating many neuronal processes, including those related to vision. Nicotine is also thought to play a key role in schizophrenia: A genetic variation of the cholinergic nicotine receptor gene, alpha ...

Visual backward masking deficits in schizotypy are observed in late but not early onset nicotine smokers

Michael Herzog, Christine Mohr

Visual backward masking (VBM) is a potential endophenotype for schizophrenia. Relative VBM deficits were also observed in high as compared to low scorers in one schizotypal subdimension (cognitive disorganisation, CogDis; Cappe et al., 2012). VBM deficits ...

Inferring about individual drug and schizotypy effects on cognitive functioning in polydrug using mephedrone users before and after clubbing

Christine Mohr, Daniela Herzig

Objective Mephedrone has been recently made illegal in Europe, but little empirical evidence is available on its impact on human cognitive functions. We investigated acute and chronic effects of mephedrone consumption on drug-sensitive cognitive measures, ...

Overexpression of parkin in the rat nigrostriatal dopamine system protects against methamphetamine neurotoxicity

Bernard Schneider

Methamphetamine (METH) is a central nervous system psychostimulant with a high potential for abuse. At high doses, METH causes a selective degeneration of dopaminergic terminals in the striatum, sparing other striatal terminals and cell bodies. We previous ...

The Insecticide Imidacloprid Causes Mortality of the Freshwater Amphipod Gammarus pulex by Interfering with Feeding Behavior

Kristin Schirmer

If an organism does not feed, it dies of starvation. Even though some insecticides which are used to control pests in agriculture can interfere with feeding behavior of insects and other invertebrates, the link from chemical exposure via affected feeding a ...

Long-term glial cell line-derived neurotrophic factor overexpression in the intact nigrostriatal system in rats leads to a decrease of dopamine and increase of tetrahydrobiopterin production

Patrick Aebischer

Parkinson's disease (PD) is characterized by the progressive degeneration of the nigrostriatal dopaminergic system. Brain delivery of glial cell line-derived neurotrophic factor (GDNF) has been shown to protect and restore the dopaminergic pathway in vario ...

Neuroprotective gene therapy for Huntington's disease using a polymer encapsulated BHK cell line engineered to secrete human CNTF

Patrick Aebischer, Nicole Déglon, Laurence Winkel

Huntington's disease (HD) is an autosomal dominant genetic disease with devastating clinical effects on cognitive, psychological, and motor functions. These clinical symptoms primarily relate to the progressive loss of medium-spiny GABA-ergic neurons of th ...
