Effect of low-dose acitretin treatment on pituitary hormones in psoriasis vulgaris: A retrospective study.

Background: It has been reported that retinoids may lead to hormonal alterations.

Aim: In this retrospective study, we aimed to study the effect of acitretin on pituitary hormones in psoriasis patients.

Evaluation of Oxidative Damage and Antioxidant Mechanisms in COPD, Lung Cancer, and Obstructive Sleep Apnea Syndrome.

Background: Oxidative damage is a major contributing factor to carcinogenesis and obstructive disorders in lungs. Current evidence suggests that the inflammatory processes yield to oxidative mechanisms, which underlie COPD, lung cancer, and obstructive sleep apnea syndrome (OSAS). This study aimed to evaluate the oxidative damage in these diseases by evaluating the oxidative and antioxidant biomarkers.

Mood and metabolic consequences of sleep deprivation as a potential endophenotype' in bipolar disorder.

It has been commonly recognized that circadian rhythm and sleep/wake cycle are causally involved in bipolar disorder. There has been a paucity of systematic research considering the relations between sleep and mood states in bipolar disorder. The current study examines the possible influences of sleep deprivation on mood states and endocrine functions among first-degree relatives of patients with bipolar disorder and healthy controls.

Serum cytokines and bone metabolism in patients with thyroid dysfunction.
