BACKGROUND AND OBJECTIVES Specific assessment of anxiety and depression is not included in routine preoperative evaluation; therefore, in cases of cardiac diseases in which the emotional status of the patient may be modified by the disease those disorders may not be diagnosed. The objective of the present study was to compare the level and prevalence of anxiety and depression in patients with c...

Introduction: Recent studies showed that nitrergic system have specific modulatory effects on electrophysiological properties of atrioventricular (AV) node. The aim of this study was to determine the effects of nitric oxide (NO) on the electrophysiological properties of isolated rabbit AV node and to investigate the role of adrenergic and cholinergic receptors in the mechanism of its action...

Introduction: Beta-carboline alkaloids of P. harmala are shown to have immune-modulatory effects in several studies. Extracts of this plant have significant anti-inflammatory effect via the inhibition of some inflammatory mediators including PGE2 and TNF-α. In postmortem studies, structural alterations to the cerebellum have been recognized, including Purkinje cell loss being re...

spasticity is one of the common complications in upper motor neuron lesions and without appropriate treatment it causes disturbances in movement pattern. assessments of patients are effective in patient`s management. modified ashworth scale (mas) is one of the criteria in qualitative assessment of spasticity, and there are lots of controversies about its validity. the purpose of this study is t...

introduction: to study the effects of polarized polychromatic noncoherent light (bioptron) therapy on patients with carpal tunnel syndrome (cts). methods: this study was designed as a randomized clinical trial. forty four patients with mild or moderate cts (confirmed by clinical and electrodiagnostic studies) were assigned randomly into two groups (intervention and control goups). at the beginn...

Electrophysiological signal generators are widely used in biomedical engineering research, education and the testing of devices hospitals. Such also available commercially. The EEG (Electroencephalography) is an electrophysiological which emitted from brain. In this study, a generator that produces experimental signals taken databases proposed. proposed reads data SD card with SDIO serial proto...

The ability to control the orientation, morphology, and electrophysiological characteristics of neurons in culture allows the construction of neural circuits with defined physiological properties. Using microfluidic protein deposition onto chemically modified glass, we achieve the controlled growth of Aplysia neurons on geometrical patterns of poly-L-lysine and collagen IV, surrounded by nonadh...

Introduction: Many studies have shown that amygdala kindling produces synaptic potentiation by induction of changes in the neuronal electrophysiological properties and inward currents both in epileptic focus and in the areas which are in connection with the epileptic focus and have important role in seizure development and progression such as hippocampal CA1 region. However, cellular mechani...

We aimed to investigate changes in electrophysiological findings in Turkish patients with restless legs syndrome (RLS), including F-wave latency (FWL), peripheral silent period (PSP), and Hoffmann reflex. The study took place in a university hospital in Turkey and involved 30 newly diagnosed RLS patients and 30 healthy controls who were matched for age and gender. Participant's demographics (ag...

BACKGROUND Neuregulins are a family of signalling proteins that orchestrate a broad range of cellular responses. Four genes encoding Neuregulins 1-4 have been identified so far in vertebrates. Among them, Neuregulin 1 and Neuregulin 3 have been reported to contribute to an increased risk for developing schizophrenia. We hypothesized that three specific variants of these genes (rs6994992 and rs3...
