چکیده

Conventional and maximum length sequence (MLS) middle latency response (MLR) procedures were compared across several parameters for control patients and patients with central nervous system lesions. There were similar findings for both populations and both types of MLR for the absolute latencies of Na and Pa waves. Middle latency waves were absent more often in the neurologic than control subjects for both the conventional and MLS-MLR procedures. Overall, more MLR waves were present for the MLS technique than for the conventional MLR technique. Differences in wave amplitude were significant for several recording sites when comparing neurologic with control groups, but findings were similar for wave amplitude when comparing the two types of MLR procedures for the neurologic population. Based on these findings, no clear diagnostic advantage was shown for using the MLS-MLR technique. These findings are further discussed.

Inclusion of Height and Limb Length when Interpreting Sympathetic Skin Response

It is more than a decade since scientists are making use of sympathetic skin response (SSR) as a clinical and research method to evaluate sympathetic nervous system. A major portion of the efferent pathway of this response is composed of non-myelinated nerves. Thus, the latency of the response may be significantly different in normal individuals with different height and limb lengths. This stud...

The Optimization of Magnetic Resonance Imaging Pulse Sequences in Order to Better Detection of Multiple Sclerosis Plaques

Background and objective: Magnetic resonance imaging (MRI) is the most sensitive technique to detect multiple sclerosis (MS) plaques in central nervous system. In some cases, the patients who were suspected to MS, Whereas MRI images are normal, but whether patients don’t have MS plaques or MRI images are not enough optimized enough in order to show MS plaques? The aim of the current study is ...

Background: Multiple sclerosis (MS) is a chronic disease that begins most commonly in young adults and is characterized pathologically by multiple areas of central nervous system (CNS) white matter inflammation, demyelination, and glial scarring. The most valuable aid for diagnosis is magnetic resonance imaging (MRI). New type of MRI has been developed on the basis of molecular diffusion which ...

CLONING AND SEQUENCING OF A MITOCHONDRIAL AUTOANTIGEN WITH IMMUNOGLOBULIN G FROM PATIENTS WITH MULTIPLE SCLEROSIS

Multiple Sclerosis (MS) is a chronic neurological disease of the central nervous system (CNS), characterised by a cellular immune response in early stages and demyelination of the CNS later. Although the cause of MS is unknown, there is much evidence that points to MS as an autoimmune disease. To test the hypotheses that an Autoantigen is involved in MS, we screened a ?gt11 human foetal spinal ...
