Laparoscopic fundoplication provides good reflux control, but side-effects due to the surgical procedure are known. Different endoluminal techniques have been introduced, but all with disappointing results. Evaluation of the feasibility and safety of a new device, which enables a totally endoluminal anterior fundoplication for the treatment of(More)
Environmental factors have long been known to regulate brain plasticity. We investigated the potential influence of social experience on ocular dominance plasticity. Fully adult female or male mice were monocularly deprived for four days and kept a) either alone or in pairs of the same sex and b) either in a small cage or a large, featureless arena. While(More)
Bone turnover and calcium homeostasis in man can only be modelled validly in Old World nonhuman primates. In order to interpret the models it is necessary to establish endocrine and biochemical parameters of bone mineral metabolism. This report is probably the first description of acute phase parathyroid responses to manipulations of blood ionised calcium,(More)
A significant portion of patients suffering from major depression remains refractory to available antidepressant treatment strategies. This highlights the need for a better understanding of the underlying neuropathology in order to develop rationale-based treatments. Here we aimed to further characterize neurobiological abnormalities of the Flinders(More)
BACKGROUND In recent years, deep brain stimulation (DBS) has emerged as a promising treatment option for patients suffering from treatment-resistant depression (TRD). Several stimulation targets have successfully been tested in clinical settings, including the subgenual cingulum (Cg25) and the medial forebrain bundle (MFB). MFB-DBS has led to remarkable(More)
Deep brain stimulation (DBS) of several targets induces beneficial responses in approximately 60% of patients suffering from treatment-resistant depression (TRD). The remaining 40% indicate that these stimulation sites do not bear therapeutic relevance for all TRD patients and consequently DBS-targets should be selected according to individual symptom(More)
To date, the effects of deep brain stimulation (DBS) on hippocampal neurogenesis have been mainly characterized in the context of memory. Acute stimulation (i.e. for 1 h) of either the entorhinal cortex or the anterior thalamus increases both cell proliferation and survival. We investigate whether stimulation applied to targets being considered for the(More)
Alcohol use disorder (AUD) is a severe chronic condition characterized by compulsive alcohol use, cravings and high relapse rates even after long periods of abstinence. It is suggested that alterations in neuronal network activity, especially in the reward pathway accompany or even mediate relapse behavior. Here we used a DSM-based rat model to map in a(More)
Use of honey as a biological indicator for heavy metal contamination entails the analysis of a greater number of samples. To date the complex sugar matrix required sample preparation using digestion methods, which were time consuming and involved a high risk of contamination or loss. It is now possible, using the method described here, to measure lead in(More)
In recent years schizophrenia has been recognized as a neurodevelopmental disorder likely involving a perinatal insult progressively affecting brain development. The poly I:C maternal immune activation (MIA) rodent model is considered as a neurodevelopmental model of schizophrenia. Using this model we and others demonstrated the association between(More)
