Melatonin Receptor Gene Polymorphism in Bipolar-I Disorder.

Background And Aim: In patients with Bipolar-I Disorder (BD-I), circadian rhythm and sleep disorders are frequently observed. Melatonin is a main regulatory hormone for the circadian rhythm. Certain studies have shown the relationship of melatonin receptor gene polymorphism with psychiatric diseases.

MicroRNA dysregulation in manic and euthymic patients with bipolar disorder.

Background: Bipolar disorder (BPD) is a major psychiatric disorder with an unclear pathophysiology. Peripheral blood samples are easily drawn, making them are good candidates for diagnosing diseases. MicroRNAs are small non-coding RNA transcripts that regulate gene expression by binding to the 3'- UTR of mRNAs and directing their degradation.

Evaluation of Oxidant/Antioxidant Status and Cytokine Levels in Patients with Cannabis Use Disorder.

Objective: Cannabis is the most commonly used illegal drug in the world and it has several adverse effects such as anxiety, panic reactions and psychotic symptoms. In this study, we aimed to evaluate oxidant, anti-oxidant status and cytokine levels in individuals with cannabis use disorder.

Methods: Thirty-four patients with cannabis use disorder and 34 healthy controls were enrolled to the study.

Evaluation of oxidant, antioxidant, and S100B levels in patients with conversion disorder.

Introduction: Various psychodynamic, neurobiological, genetic, and sociocultural factors are believed to be involved in the etiology of conversion disorder (CD). Oxidative metabolism has been shown to deteriorate in association with many health problems and psychiatric disorders. We evaluated oxidative metabolism and S100B levels in the context of this multifactorial disease.
