Effects of agmatine, glutamate, arginine, and nitric oxide on executive functions in children with attention deficit hyperactivity disorder.

In this study, we aimed to investigate the effects of agmatine, nitric oxide (NO), arginine, and glutamate, which are the metabolites in the polyamine pathway,  on the performance of executive functions (EF) in attention deficit hyperactivity disorder (ADHD). The ADHD group included 35 treatment-naive children (6-14 years old) who were ewly diagnosed with ADHD. The control group consisted of 35 healthy children with the same age and sex, having no previous psychiatric disorders.

Evidence supporting the role of telomerase, MMP-9, and SIRT1 in attention-deficit/hyperactivity disorder (ADHD).

Growing evidence suggests that telomeres, telomerase, matrix metalloproteinase-9 (MMP-9), and SIRT1 (sirtuin1) are involved in the pathophysiology of neuropsychiatric and neurodevelopmental disorders. However, whether these molecules are contributors to attention-deficit/hyperactivity disorder (ADHD) has been little explored and poorly understood. This study aimed to determine the potential role of telomerase, MMP-9, and SIRT1 in children with ADHD.

Determination of levels of oxidative stress and nitrosative stress in patients with epilepsy.

Background: Epilepsy is one of the most common neurological diseases. The underlying pathophysiological mechanisms in epilepsy are still unknown. Oxidative stress is believed to be one of the factors involved in the pathogenesis of epileptogenesis.

Increased Irisin Concentrations in Patients with Crimean- Congo Hemorrhagic Fever.

Crimean-Congo Hemorrhagic Fever (CCHF) is a life-threatening viral infection. The pathogenesis of the disease is not well understood. The aim of this study was to determine the change in irisin concentrations in patients with CCHF.

Oxidative stress in the adult and pediatric patients with Crimean-Congo haemorrhagic fever.

Background & Objectives: Crimean-Congo haemorrhagic fever (CCHF) can be fatal with bleeding, shock and disseminated intravascular coagulopathy (DIC). Although similar genetic strains have been defined, the causes of the clinical differences between the cases are yet to be found. We aimed to demonstrate the balance between oxidant and antioxidant system in CCHF.
