optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano rods (zonrs) as a nucleus layer were fabricated on the indium tin oxide (ito) by chronoamperometry (ca) in a...

toll like receptors (tlrs) recognize pathogens and generate an immediate defense response by inducing the production of pro-inflammatory cytokines, which rapidly destroy or limit the pathogens. in their bridging role, tlr downstream signals link innate and adaptive immunity, particularly by mediating dc maturation and activation of pathogen specific t lymphocytes. these pathways lead to the act...

every year, millions of moslems depart to saudi arabia from more than one hundred countries around the world for paying to hajj precept. high percentages of these pilgrims suffer from an influenza-like illness (ili). this study was designed and conducted on 32370 iranian pilgrims (36% of total number of iranian pilgrims) to evaluate the incidence of the illness and determination of influenza va...

nanostructures of noble metal materials have been used in organic solar cells for enhancement of performance and light trapping. in this study, we have introduced branched silver cauliflower-like nanopatterns as sub-wavelength structured metal grating in organic solar cells. self-assembled fabrication process of branched nanopatterns was carried out on a bio-template of cicada wing nanonipple a...

pelizaeus­-merzbacher-like disease (pmld) is a hypomyelinating leukoencephalopathy disorder with a genetically heterogeneous pattern. mutations in the gja12/gjc2 gene cause one form of autosomal recessive pelizaeus­-merzbacher-like disease. here, we report a new mutation in a ­10-month-old girl with nystagmus, psychomotor delay, hypotonicity, head nodding and dysmyelination from healthy second ...
