Changes in Expression of DNA-Methyltransferase and Cannabinoid Receptor mRNAs in Blood Lymphocytes After Acute Cannabis Smoking.

Background: Cannabis use is a component risk factor for the manifestation of schizophrenia. The biological effects of cannabis include effects on epigenetic systems, immunological parameters, in addition to changes in cannabinoid receptors 1 and 2, that may be associated with this risk. However, there has been limited study of the effects of smoked cannabis on these biological effects in human peripheral blood cells.

Cholinergic regulation of mood: from basic and clinical studies to emerging therapeutics.

Mood disorders are highly prevalent and are the leading cause of disability worldwide. The neurobiological mechanisms underlying depression remain poorly understood, although theories regarding dysfunction within various neurotransmitter systems have been postulated. Over 50 years ago, clinical studies suggested that increases in central acetylcholine could lead to depressed mood.

The catecholaminergic-cholinergic balance hypothesis of bipolar disorder revisited.

Bipolar disorder is a unique illness characterized by fluctuations between mood states of depression and mania. Originally, an adrenergic-cholinergic balance hypothesis was postulated to underlie these different affective states. In this review, we update this hypothesis with recent findings from human and animal studies, suggesting that a catecholaminergic-cholinergic hypothesis may be more relevant.

Lithium-induced renal insufficiency: a longitudinal study of creatinine increases in intellectually disabled adults.

Background: Lithium has been shown to increase serum creatinine levels in a subgroup of patients. However, lithium-induced increases in serum creatinine have not been well studied with regard to timing, trajectory, or predictability.

Methods: The medical records of 16 intellectually disabled individuals treated with lithium between 1980 and 2010 in whom serum creatinine levels peaked at 1.
