abstract background: invasive fungal infection is an opportunistic infection caused commonly by mucoraccae and aspergillus. it mostly occurs in patients with underlying disease. since it has a high mortality and morbidity rate, considering a treatment strategy seems necessary. objective: since there has not been a clear protocol for treating these patients, we decided to establish a protocol ...
Background and Objectives: Behavioral Inhibition System (BIS) brings about an increase in excitation, evoking emotional states of anxiety, and experiencing negative emotions; and it seems individuals who have activeBehavioral Inhibition System, feel more anxiety in confrontation with stressful events. On the other hand, being exposed to stressful life can weaken various functions of immune syst...
Purpose: This study is designed to determine the sex differences in brain weight and volume of left hemisphere and its gray and white matters in right-handed normal subjects and the right-handed subjects which were suffered from Alzheimer and Parkinson diseases. Materials and Methods: This study was performed on 72 normal human brains (38 male, 34 female), 11 brains suffered from Alzheimer (4 ...
Introduction: MS disease destroys the myelin of the central nervous system. MS causing damage to the myelin sheath of the brain and the spinal cord. The mechanism is hurt by the immune system .and disruption of myelin producing cells or disconnect interconnected processes by disconnect inner white. MS is an autoimmune disease when leukocyte antigen system varies autoimmune disease like MS ...
Background: Leukocyte infiltration into the central nervous system (CNS) in diseases like multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE) have been implicated in subsequent disease pathogenesis and progression. It suggested that vitamin D3 (active form of vitamin D) ameliorates the symptoms of EAE when administered after the onset of clinical sings. The aim of this s...
In 1948, WHO defined health as “a state of complete physical, mental, and social wellbeing not merely the absence disease or infirmity”. Brain must be key to health, by WHO, because brain is agent all our actions mediator experiences. However, neurological, psychiatric, researchers seldom work together achieve health.
Introduction: Many theories have been proposed about the etiology of autism. One is related to brain connectivity in patients with autism. Several studies have reported brain connectivity changes in autism disease. This study was performed on Electroencephalogram (EEG) studies that evaluated patients with autism, using functional brain connectivity, and compared them with typically-developing i...
Magnetic Resonance Images (MRI) of the Brain is a significant tool to diagnosis Alzheimer's disease due its ability measure regional changes in brain that reflect progression detect early stages disease. In this paper, we propose new model adopts Bat for parameter optimization problem Support vector machine (SVM) diagnose Alzheimer’s via MRI biomedical image. The proposed uses image classificat...
conclusions cyclosom and histamine synergistically exert catalepsy in old rats. in light of these data, the combination of the decreased brain level of somatostatin and increased brain level of histamine may be of pathogenic relevance for extrapyramidal signs in pd. results cyclosom (0.2, 1.0, and 5.0 µg) and histamine (1.0 and 10.0 µg) alone were ineffective in both young and old animals. in c...
Background and purpose: Migraine affects about 12% of the general population and is one of the causes of cerebral parenchymal. Applying cross sectional imaging of brain particularly MRI opens a new approach in diagnosis of migraine pathogenesis and could highly influence the patients’ follow up program. We investigated anatomical MR imaging abnormality in people with and without migraine in sen...
