Limbic-hypothalamic-pituitary-adrenal axis activity and ventricular-to-brain ratio studies in affective illness and schizophrenia.
S.C. Risch,R.R.J. Lewine,Ned H. Kalin,R.D. Jewart,E.D. Risby,Jane Caudle,M. Stipetic,J Turner,M B Eccard,W E Pollard +9 more
TL;DR: Results suggest that VBR is not highly associated with alterations in LHPA activity, at least as determined cross-sectionally, and further longitudinal studies with reference to diagnostic subtypes, severity, symptom profiles, and more specific neuroanatomic regions may allow the elucidation of possible relationships between LHPA pathology and structural brain alterations.

Lithium administration modulates platelet Gi in humans.
TL;DR: Increased pertussis toxin stimulated ADP-ribosylation in the absence of changes in alpha i content could be explained by a shift in platelet Gi in favor of its undissociated, inactive form, which would be consistent with increased platelet adenylyl cyclase activity found in these same subjects after lithium.

Lateral Ventricle-Brain Ratio and Balance Between CSF HVA and 5-HIAA in Schizophrenia
R.R.J. Lewine,S.C. Risch,E.D. Risby,M. Stipetic,R.D. Jewart,M B Eccard,Jane Caudle,W E Pollard +7 more
TL;DR: The data suggest that it is the balance between HVA and 5-HIAA rather than their absolute levels which is associated with brain morphology and that this relationship between brain chemistry and morphology may be characteristic of the normal range of functioning for these systems.

Hypothalamic--pituitary--adrenal axis and monoamine transmitter activity in depression: a pilot study of central and peripheral effects of electroconvulsive therapy.
TL;DR: Central and peripheral measures of hypothalamic--pituitary--adrenal (HPA) axis and monoamine neurotransmitter activity were assessed in 8 depressed patients during a medication-free period and again after completion of a course of electroconvulsive therapy (ECT).
