macrophage activating syndrome (mas) is a life-threatening disease seen in autoimmune diseases including lupus erythematosus, rheumatoid arthritis, still's disease, polyarteritis nodosa. it is characterized by fever, pancytopenia, liver failure, coagulopathy, and neurologic symptoms and high serum ferritin. a 27 yr. old female patient was admitted in shahid mostafa khomeini hospital (tehra...

primary immunodeficiencies (pid) are a group of disorders, characterized by an unusual susceptibility to infections. delay in diagnosis results in increased morbidity and mortality in affected patients. the purpose of this study was to determine the mortality rate of iranian immunodeficient patients referred to children medical center hospital affiliated to tehran university of medical sciences...

This paper presents a new approach to compare several non-overconstrained solutions of the 3RRR Spherical Parallel Manipulator (SPM). The 3 − RRR SPM is known to be highly overconstrained, which causes several problems of mounting the mechanism, but has the advantage of having high rigidity thus a good accuracy. Several works in the literature proposed non-overconstrained versions of this mecha...

• Exploring of the discrimination power of deep-UV RRS (excitation below 260 nm). This offers higher sensitivity and reduces fluorescence interference, but results in a reduced spectral information content Nevertheless, we could discriminate pyrene derivatives based on their RRS spectra.. With state-of-the-art computational methods we could simulate RRS spectra using linearresponse time-depende...

The enhancement of Raman scattering (RS), resonance Raman scattering (RRS), and fluorescence from molecules adsorbed en silver-lsiand films is reported. A helrarchy of enhancements 1s found: 10 for RS, 10 for RRS, and 0.1-10 for fluorescence, depending on the quantum yield of the free molecule. Using the framework of the electromagnetic theory of surface-enhanced Raman scattering, generalized t...

In the last decade, the revolution in sequencing technologies has deeply impacted crop genotyping practice. New methods allowing rapid, high-throughput genotyping of entire crop populations have proliferated and opened the door to wider use of molecular tools in plant breeding. These new genotyping-by-sequencing (GBS) methods include over a dozen reduced-representation sequencing (RRS) approach...

The main focus in the development of wireless communications engineering is providing higher data rates, using lower transmission power, and maintaining quality of services in complicated physical environments, such as an urban area with high-rise buildings, a randomly profiled terrestrial ground and so on. In order to achieve these goals, there has been substantial progress in the development ...

The aggregation and photochemistry of the copper (II) 3, 4 00, 4 00, 4 000-tetrasulfonated phthalocyanine, free base phthalocyanine and copper (II) phthalocyanine have been studied by UV–VIS absorption spectroscopy and resonance Raman spectroscopy (RRS). The vibrational mode n3 of (Cu(tsPc) 4K has been used as a probe in RRS measurements. The photochemistry of monomers and dimers of (Cu(tsPc) h...

Resonance Raman spectroscopy (RRS) possesses many characteristics that are important for detecting, identifying and monitoring chemical effluents. Raman scattering is a coherent, inelastic, two-photon scattering process where an exciting photon of energy hv promotes a molecule to a virtual level and the subsequently emitted photon is shifted in frequency in accordance with the rotational-vibrat...
