Changes of the tumor necrosis factor-alpha (TNF-alpha) system have been shown to be involved in the development of psychiatric disorders and are additionally associated with changes in body weight as well as endocrine and metabolic changes in psychiatric patients. TNF-alpha might, for example, contribute to the pathogenesis of depression by an activation of(More)
Changes regarding the immune system and specifically the cytokine system, of which tumor necrosis factor-alpha (TNF-alpha) is a part, have been shown to be involved in the development of neurological and psychiatric disorders such as multiple sclerosis, Parkinson's and Alzheimer's disease, depression, schizophrenia or narcolepsy. Besides, there is evidence(More)

BACKGROUND Antisaccade deficits are a well-documented pathophysiological characteristic in schizophrenia. However, it is yet unclear whether these findings reflect a specific oculomotor deficit, general psychomotor impairment or disturbance in executive control mechanisms. METHODS Performance in a manual stimulus-response compatibility (SRC) task and a(More)
Nervous and immune system interact through many different messenger substances such as neurotransmitters, cytokines or neuropeptides. For instance, neuropeptides are capable of affecting the metabolism of cells belonging to the immune system. Conversely, cytokines such as tumor necrosis factor (TNF)-alpha, interferon (IFN)-alpha and IFN-gamma, contribute to(More)
We have studied the mechanism by which a previously described primary muscle culture growing on microcarriers predominantly expresses fast myosin heavy chain (MHC) IId/x. We have measured MHC IId/x mRNA and protein levels, mRNA of MHC I and markers of muscle metabolism, insulin-like growth factor (IGF)-1 and mechano-growth factor (MGF) transcripts,(More)
Glucose is the primary source of energy for the human brain. Previous literature has shown that varying blood glucose levels may have a strong impact on behaviour, subjective mood, and the intensity of the BOLD signal measured in fMRI. Therefore, blood glucose levels varying even within the normal range may interact with cognitive and emotional processing(More)
Glucose metabolism serves as the central source of energy for the human brain. Little is known about the effects of blood glucose level (BGL) on higher-order cognitive functions within a physiological range (e.g., after overnight fasting). In this randomized, placebo-controlled, double blind study, we assessed the impact of overnight fasting (14 h) on brain(More)
Previous literature has shown that hypoglycemia influences the intensity of the BOLD signal. A similar but smaller effect may also be elicited by low normal blood glucose levels in healthy individuals. This may not only confound the BOLD signal measured in fMRI, but also more generally interact with cognitive processing, and thus indirectly influence fMRI(More)
