Novel designs of demultiplexers based on photonic crystal fibers (PCF) s and photonic crystal waveguides (PCW) s are presented here. We have considered two types of PCFs and PCWs, namely Dual concentric core PCF, Multicore PCF, PCW with dielectric rods in air and PCW with air holes in dielectric background. Finite difference time domain method (FDTD) is employed to analyze all these devices at ...

objective: multiple sclerosis (ms) is a disease with a detrimental effect on functional status. the present study investigated the effect of a sexual therapy program on the quality of life (qol) of women with multiple sclerosis. method: women with multiple sclerosis and sexual dysfunction (n = 30) were selected, and were randomly assigned into the treatment (n = 15), or the control groups (n = ...

Inroduction: Hybrid diffusion imaging (HYDI) is a diffusion-weighted (DW) technique whose encoding scheme is composed of multiple concentric (spherical) shells of constant diffusion weighting in q-space, which may be used to characterize the signal behavior with low, moderate, and high diffusion weighting [1]. The zero-displacement probability (Po) describes the probability density of water mol...

A 66-year-old female was transferred from an outside hospital for possible ST segment elevation myocardial infarction (STEMI). The patient reported feeling poorly for the last day, with epigastric pain, nausea, and multiple episodes of vomiting. Patient’s medical history was significant for diabetes mellitus, hypertension, atrial fibrillation, and multiple sclerosis. Electrocardiogram (EKG) was...

objective(s): regulatory t cells, including cd4+cd25+fox3+ and cd8+cd28- cells play an important role in regulating the balance between immunity and tolerance. since multiple sclerosis is an inflammatory autoimmune disease, regulatory t cells are considered to be involved in its pathogenesis. in this study, we investigated the circulatory numbers of the two mentioned types of regulatory t cells...

points of differentiation are reevaluated. For appreciation of the essential morphological features by pathologists. continued use of our original six histological types is recommended, since the four histological types of the Rye classification, although valuable for clinicians, do not convey morphological connotations. The significance of the Reed-Sternberg (R-S) cell variants are reviewed, w...

Clinically isolated syndromes (CIS), such as optic neuritis, brainstem or spinal cord syndromes are frequently the first clinical presentations of multiple sclerosis. However, not all CIS patients develop multiple sclerosis and in those who do, disability is highly variable. In previous follow-up studies, brain lesions on T2-weighted MRI are associated with increased risk of multiple sclerosis ...

Central nervous system symptoms in patients with primary Sjogren`s syndrome are rare. They can present as extraglandular manifestations and require a differential diagnosis from multiple sclerosis. Due to a variety of presentations, Sjogren`s syndrome with neurologic involvement may be difficult to diagnose. Here, we report a case of a 75-year-old woman who was first diagnosed with multiple scl...

Over the years, working in various roles, I have done quite a lot of work in the area of team facilitation and conflict resolution. Sometimes this has been with groups of doctors like general practitioners (GPs) who are not getting along with each other. These days, a lot of my work is with teams of hospital doctors who are having difficulty in balancing their clinical and training obligations....
