Interfacing aptamer-modified nanopipettes with neuronal media and ex vivo brain tissue

Nako Nakatsuka, Anna Burdina, Annina Stuber

Aptamer-functionalized biosensors exhibit high selectivity for monitoring neurotransmitters in complex environments. We translated nanoscale aptamer-modified nanopipette sensors to detect endogenous dopamine release in vitro and ex vivo. These sensors empl ...

Gas-phase structures reflect the pain-relief potency of enkephalin peptides

Vladimir Kopysov, Aleksandr Pereverzev

We use cold ion spectroscopy and quantum-chemical computations to solve the structures of opioid peptides enkephalins in the gas phase. The derived structural parameters clearly correlate with the known pharmacological efficiency of the studied drugs, sugg ...

Stress Impacts the Regulation Neuropeptides in the Rat Hippocampus and Prefrontal Cortex

Gregor Rainer, Laura Lozano Montes, Nan Zhao

Adverse life experience increases the lifetime risk to several stress-related psychopathologies, such as anxiety or depressive–like symptom following stress in adulthood. However, the neurochemical modulations triggered by stress have not been fully charac ...

Keys to Lipid Selection in Fatty Acid Amide Hydrolase Catalysis: Structural Flexibility, Gating Residues and Multiple Binding Pockets

Ursula Röthlisberger, Andrea Cavalli, Pablo Campomanes Ramos, Giulia Palermo

The fatty acid amide hydrolase (FAAH) regulates the endocannabinoid system cleaving primarily the lipid messenger anandamide. FAAH has been well characterized over the years and, importantly, it represents a promising drug target to treat several diseases, ...

Altered Gaba And Somatostatin Modulation Of Proprioceptive Feedback After Spinal Cord Injury In Lamprey

David Parker

While various changes occur after spinal cord lesions, their influence on functional recovery is generally unclear. We have shown changes in proprioceptor and locomotor network properties below lesion sites in the lamprey spinal cord. The proprioceptive sy ...

Phosphocreatine line with changes in localised 31P MRS of exercising muscle at 7T

Rolf Gruetter, Christine Nabuurs

The aim was to investigate changes in the line width of high-energy phosphates solely originating from the intramyocellular compartment by temporally resolved localised 31P-MRS after aerobic calf muscle exercise. Semi-Laser [2] localised 31P-MRS of gastroc ...

Impact of Carbon-Nanotube Substrate Coating in Neuronal Networks

Luca Gambazzi

The interest in new materials and their application in the neuroscience are growing incredibly fast. Current research interests are increasingly focusing on new artificial materials and their direct effects on the central nervous systems so that it would b ...

Enkephalins interfere with early phases of voluntary ethanol drinking

Maria del Carmen Sandi Perez

The relationship between the opiate peptides Leu-enkephalin and [D-Ala2-Met5]enkephalinamide (DAME) and the initial expression and maintenance of ethanol preference was studied in male Wistar rats. Subcutaneous administration of both peptides prior to the ...

Administration of leu-enkephalin impairs the acquisition of preference for ethanol

Maria del Carmen Sandi Perez

The effects of subcutaneous administration of leu-enkephalin (LEU-E) (10, 100 and 300 micrograms/kg) and LEU-E (100 micrograms/kg) plus naloxone (2.5 mg/kg) on ethanol preference and fluid intake have been investigated in rats. Under our procedural conditi ...

Beta-endorphin administration interferes with the acquisition and initial maintenance of ethanol preference in the rat

Maria del Carmen Sandi Perez

Attention has been focused on the possibility of an interaction between the endorphinergic system and ethanol intake. In the present study, the effects of subcutaneous (SC) administration of beta-endorphin (beta-E) (0.25, 1 and 5 micrograms/kg) and/or nalo ...
