BACKGROUND Obsessive-compulsive disorder (OCD) is associated with cognitive dysfunction. Although there are several studies focused on the neurobiology of OCD, little is known about the biological correlates of the cognitive deficit linked to this disorder. The aim of our study was to examine the association between cognitive impairment and current source density markers in patients with OCD. ...

We hypothesized that post-movement beta synchronization (PMBS) and cortico-muscular coherence (CMC) during movement termination relate to each other and have similar role in sensorimotor integration. We calculated the parameters and estimated the sources of these phenomena.We measured 64-channel EEG simultaneously with surface EMG of the right first dorsal interosseus muscle in 11 healthy volun...

Regional variations and substrates of high-frequency rhythmic activity induced by cholinergic stimulation were studied in hippocampal slices with 64-electrode recording arrays. (1) Carbachol triggered beta waves (17.6 +/- 5.7 Hz) in pyramidal regions of 75% of the slices. (2) The waves had phase shifts across the cell body layers and were substantially larger in the apical dendrites than in cel...

pigeons can be carriers of some human pathogens and contribute to transmission and spread of drug resistant infectious agents to human. considering many people’s interests to keep pigeons, present study was conducted to pcr detection of escherichia coli o157:h7 that is responsible for outbreaks of human intestinal diseases and fatal haemolytic-uraemic syndrome worldwide and evaluation of resist...

background: poultry and poultry products are among the major sources of salmonella infections for humans. increasing occurrence of antimicrobial resistance among salmonellae has become a serious public health concern. the detection of extended spectrum b-lactamase (esbl) producers among salmonella spp. has increased in recent years. objectives: the purpose of this study was to investigate the a...

OBJECTIVE To investigate quantitative EEG (qEEG) in anorexia nervosa (AN) and bulimia nervosa (BN) in comparison with healthy controls. METHODS Resting EEG was recorded in 30 healthy females (age: 27.1+/-5.5), 16-AN females (age: 26.4+/-9.5) and 12-BN females (age: 27.0+/-6.3). Cortical EEG sources (delta, theta, alpha 1, alpha 2, beta 1, beta 2) were modeled by LORETA solutions. The statisti...

Walking on two legs is inherently unstable. Still, we humans perform remarkable well at it, mostly without falling. To gain more understanding of the role of the brain in controlling gait stability we measured brain activity using electro-encephalography (EEG) during stabilized and normal walking. Subjects walked on a treadmill in two conditions, each lasting 10 min; normal, and while being lat...

OBJECTIVE Non-steroidal anti-inflammatory drugs such as ibuprofen have a protective role on risk of Alzheimer's disease (AD). Here we evaluated the hypothesis that long-term ibuprofen treatment affects cortical sources of resting electroencephalographic (EEG) rhythms in mild AD patients. METHODS Twenty-three AD patients (13 treated AD IBUPROFEN; 10 untreated AD PLACEBO) were enrolled. Resting...

background: the most important problem in regular transfusion dependent β-thalassemia major is cardiac dysfunction due to iron deposition in it. the aim of this study was to evaluate correlation between serum ferritin levels and cardiac function in β-thalassemia major in mofid hospital. materials and methods: there were 112 β-thalassemia patients with a mean age of 13.55± 6.12 years, of whom 49...
