the application of nmo (normal moveout) has been recognized as an effective method of generating quasi-zero-offset traces in traditional common-midpoint processing. artifacts of the nmo method relate to the nmo-stretch effects. conventional application of normal-moveout correction to a common-midpoint (cmp) reflection generates a stretch that increases with offset and decreases with zero-offset...

the application of traditional nmo-correction techniques in the processing of seismic data may result in severe distortion. this distortion is observed as a decrease in frequency content (nmo stretch). this may be seen as the source of problems in the processing with stretch. in this paper, cnmo method is applied which doesn't have the `stretching effects' of conventional nmo correcti...

Background: Neuromyelitis optica (NMO) and multiple sclerosis (MS) are auto immune demyelinating disorders. Both MS and NMO patients suffer from urinary dysfunction.  Objectives: Investigation of frequency and severity of urinary symptoms in two groups of MS and NMO patients. Materials & Methods: 56 MS patients and 20 NMO patients were enrolled in this cross sectional study conducted in Isfah...

Hinson et al. (1) suggested a unique mechanism for the pathogenesis of neuromyelitis optica (NMO), a neuroinflammatory disease caused by binding of an autoantibody (NMO-IgG) to aquaporin-4 (AQP4) on astrocyte plasma membranes. AQP4 is expressed as long (called M1) and short (called M23) isoforms, the latter forming orthogonal arrays of particles (OAPs). Hinson et al. (1) reported that M1-AQP4 i...

purpose: neuromyelitis opitca (nmo) is an autoimmune disease that relates to deposition of anti-aquaporin-4 (aqp4) igg in the central nervous system (cns). however, called seronegative nmo when patients are negative for aqp4 antibody. nevertheless, nmo is most probably an antibody mediated disease. the aim of this study was to assess the association between seronegative nmo disease and variatio...

Antibodies to aquaporin-4 (called NMO-IgG or AQP4-Ab) constitute a sensitive and highly specific serum marker of neuromyelitis optica (NMO) that can facilitate the differential diagnosis of NMO and classic multiple sclerosis. NMO-IgG/AQP4-Ab seropositive status has also important prognostic and therapeutic implications in patients with isolated longitudinally extensive myelitis (LETM) or optic ...

Background and Objective: Multiple Sclerosis (MS) is the most common neurological disease of young adults in Western countries. The spectrum of demyelinating disease in Western countries is characterised by predominance of conventional MS and small proportion of neuromyelitis optica (NMO). NMO is similar to optic-spinal MS reported in Asia in many aspects. It has been argued that relapsing NMO ...
