High sensitivity of brain octopamine levels to stress

Octopamine Sensitivity of the Blood-brain Barrier of an Insect

Octopaminergic sensitivity of the glia that form the blood—brain barrier of the cockroach was examined using microelectrode recordings of the potential developed across this barrier layer, the perineurium. Exposure to 10~moll~ DL-octopamine had no significant effect upon the changes in potential induced by substitution of Tris for external sodium. Treatment with concentrations ranging from 10~m...

Intraventricular infusions of octopamine which raised brain octopamine concentrations

Intraventricular infusions of octopamine which raised brain octopamine concentrations more than 20 000-fold resulted in reductions in brain noradrenaline and dopamine by as much as 90% without affecting the alertness or activity of normal rats. As this reduction of brain catecholamines is much greater than any reported in hepatic coma, we do not believe that values observed in experimental hepa...

Relations of serum high-sensitivity C-reactive protein and interleukin-6 levels with silent brain infarction.

BACKGROUND AND PURPOSE Small silent brain infarction (SBI) is often found on magnetic resonance (MR) images of apparently healthy individuals at cardiovascular risk. Particularly, small SBI found in subcortical white matter, basal ganglia, or thalamus is thought to be caused by cerebral small vessel disease. Although several lines of evidence suggest a role of inflammatory processes in atheroth...

The Effect of Resistance Training on Levels of Interlukine-6 and High-Sensitivity C - reactive protein in Older-Aged Women

Introduction: Aging is associated with elevated levels of some proinflammatory factors and exercise is a non-invasive intervention to improve immune function among older adults .The aim of the study was to compare resistance training effects on interlukine-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) levels in older-aged women. Methods: The study was quasi-experimental and for...
