Diffusion behavior of cerebral metabolites of congenital portal systemic shunt mice assessed noninvasively by diffusion-weighted H-1 magnetic resonance spectroscopy

Hongxia Lei, Nicolas Kunz, Masoumeh Dehghani Moghadam

Diffusion-weighted H-1-MRS (DW-MRS) allows for noninvasive investigation of the cellular compartmentalization of cerebral metabolites. DW-MRS applied to the congenital portal systemic shunt (PSS) mouse brain may provide specific insight into alterations of ...

Impact of Caffeine Consumption on Type 2 Diabetes-Induced Spatial Memory Impairment and Neurochemical Alterations in the Hippocampus

Rolf Gruetter, João Miguel das Neves Duarte

Diabetes affects the morphology and plasticity of the hippocampus, and leads to learning and memory deficits. Caffeine has been proposed to prevent memory impairment upon multiple chronic disorders with neurological involvement. We tested whether long-term ...

Social isolation stress and chronic glutathione deficiency have a common effect on the glutamine-to-glutamate ratio and myo-inositol concentration in the mouse frontal cortex

Rolf Gruetter, Alberto Corcoba, Kim Do, João Miguel das Neves Duarte

Environmental stress can interact with genetic predisposition to increase the risk of developing psychopathology. In this work, we tested the hypothesis that social isolation stress interacts with impaired glutathione synthesis and have cumulative effects ...

In vivo neurochemistry of the ventral striatum and social competition in Homo sapiens

Alina Veronika Irene Strasser

Ventral striatal function and trait anxiety have been shown to influence reward-seeking behaviour and social competition in humans. Moreover, social status perceptions have been shown to modulate ventral striatal function. The neurochemical underpinnings o ...

N-acetylcysteine normalizes neurochemical changes in the glutathione-deficient schizophrenia mouse model during development

Rolf Gruetter, João Miguel das Neves Duarte, Kim Do

Background: Glutathione (GSH) is the major cellular redox-regulator and antioxidant. Redox-imbalance due to genetically impaired GSH synthesis is among the risk factors for schizophrenia. Here we used a mouse model with chronic GSH deficit induced by knock ...

Proton and phosphorus magnetic resonance spectroscopy of a mouse model of Alzheimer's disease

Rolf Gruetter, Patrick Aebischer, Bernard Schneider, Cristina Ramona Cudalbu, Hongxia Lei, Sharon Janssens, Lili Sun-Reimer

The development of new diagnostic criteria for Alzheimer's disease (AD) requires new in vivo markers reflecting early pathological changes in the brain of patients. Magnetic resonance (MR) spectroscopy has been shown to provide useful information about the ...

Biophysical Basis of the Diffusion-Weighted Magnetic Resonance Signal in the Rat Brain

Nicolas Kunz

Nuclear magnetic resonance (NMR) can be used in-vivo in a vast array of applications, such as anatomical imaging (magnetic resonance imaging, MRI), localized chemical composition characterization (magnetic resonance spectroscopy, MRS), cellular structure a ...

Neurochemical profile of the developing mouse cortex determined by in vivo1H NMR spectroscopy at 14.1 T and the effect of recurrent anaesthesia

Rolf Gruetter, João Miguel das Neves Duarte, Kim Do

P>The neurochemical profile of the cortex develops in a region and time specific manner, which can be distorted by psychiatric and other neurological pathologies. Pre-clinical studies often involve experimental mouse models. In this study, we determined th ...

Caffeine consumption attenuates neurochemical modifications in the hippocampus of streptozotocin-induced diabetic rats

Rolf Gruetter, João Miguel das Neves Duarte

Type 1 diabetes can affect hippocampal function triggering cognitive impairment through unknown mechanisms. Caffeine consumption prevents hippocampal degeneration and memory dysfunction upon different insults and is also known to affect peripheral glucose ...

In vivo H-1 NMR measurement of glycine in rat brain at 9.4 T at short echo time

Rolf Gruetter, Lijing Xin, Giulio Gambarota, Chiara Perazzolo

Glycine is an amino acid present in mammalian brain, where it acts as an inhibitory and excitatory neurotransmitter. The two detectable protons of glycine give rise to a singlet at 3.55 ppm that overlaps with the more intense myo-inositol resonances, and i ...
