Evaluation of the Levels of Blood Cells, Vitamin D, and Inflammatory Factors in Children with PFAPA Syndrome.

Background: The syndrome of periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA syndrome) is the most common type of recurrent fever in childhood. The aim of this study was evaluation of the levels of blood cells, vitamin D, and inflammatory factors in children with PFAPA syndrome.

Methods: This retrospective descriptive study was conducted on the recorded information of children with PFAPA syndrome referred to the children's specialty clinic of Imam Khomeini Hospital in Ilam city from March 2021 to February 2022.

Task modulates functional connectivity networks in free viewing behavior.

In free visual exploration, eye-movement is immediately followed by dynamic reconfiguration of brain functional connectivity. We studied the task-dependency of this process in a combined visual search-change detection experiment. Participants viewed two (nearly) same displays in succession.

Variations of glutamate concentration within synaptic cleft in the presence of electromagnetic fields: an artificial neural networks study.

Glutamate is an excitatory neurotransmitter that is released by the majority of central nervous system synapses and is involved in developmental processes, cognitive functions, learning and memory. Excessive elevated concentrations of Glu in synaptic cleft results in neural cell apoptosis which is called excitotoxicity causing neurodegenerative diseases. Hence, we investigated the possibility of extremely low frequency electromagnetic fields (ELF-EMF) as a risk factor which is able to change Glu concentration in synaptic clef.

Potential impact of air pollution on multiple sclerosis in Tehran, Iran.

Background: Multiple sclerosis (MS) incidence has dramatically increased in Tehran, Iran. The health impact of air pollution in Tehran underscores the attention to a possible association to this environmental risk factor. In this study, the authors aimed to analyze the spatial distribution of prevalent MS cases and their association with the spatial patterns of air pollution.

Synaptosomal acetylcholinesterase activity variation pattern in the presence of electromagnetic fields.

Acetylcholinesterase (AChE) is the enzyme that controls the acetylcholine (ACh) concentrations in cholinergic synaptic clefts by hydrolyzing ACh to choline and acetate. Cholinergic synapses are involved in important functions such as learning, memory and cognition. In this study, we investigated the effects of a wide range of extremely low frequency electromagnetic fields (ELF-EMFs) on synaptic ACh concentrations through AChE enzyme activity assay.
