Glimpses of Neurobiological Underpinnings of Bipolar Disorder

A major development in the study of bipolar disorder, in the recent years, has been the identification of indicators of structural and functional brain abnormalities. That the unfavorable outcome of some patients could be a result of subde brain dysfunction has been hypothesized. It has been suggested that there is something about the process of bipolar illness that may itself be the cause of t...

Neurobiological Underpinnings of the Estrogen - Mood Relationship.

Women are at a higher risk than men to develop mood disorders and depression. The increased risk is associated with fluctuating estrogen levels that occur during reproductive cycle events, particularly during the menopausal transition, a time characterized by drastic fluctuations in estrogen levels and increases in new onset and recurrent depression. Conversely, recent data show that hormone th...

postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Neurotransmitters and suicidal behavior. The evidence from cerebrospinal fluid studies.

Studies of neurotransmitter metabolites in cerebrospinal fluid (CSF) were initially focused on depressive illness. Although several studies have demonstrated low concentrations of the serotonin metabolite, 5-hydroxyindoleacetic acid (5-HIAA), and the dopamine metabolite, homovanillic acid (HVA), in depressed patients, these early studies may have been biased by concomitant administration of ant...
