Neuromyelitis optica (also known as Devic's disease or Devic's syndrome) is an uncommon disorder in pediatric age group, and is characterized by acute or subacute optic neuritis and transverse myelitis. Here we report an 11- year- old female child with relapsing Neuromyelitis optica (NMO) confirmed by positive NMO- IgG antibody and had clinical recovery with high dose methyl prednisolone t...

Transitions, or periods of change, in medical career pathways can be challenging episodes, requiring the transitioning clinician to take on new roles and responsibilities, adapt to new cultural dynamics, change behaviour patterns, and successfully manage uncertainty. These intensive learning periods present risks to patient safety. Simulation-based education (SBE) is a pedagogic approach that a...

Background and objectives: Nasturtium officinale W.T.Aiton (Brassicaceae) is used as an edible vegetable in various parts of Iran. The aim of the present study was to investigate the protective activity of the methanolic extract of Nasturtium officinale against gamma-radiation-induced hepatotoxicity in terms of histopathological changes. Methods: Male C57 mice were divided int...

Backround: Tebuconazole is a systemic fungicide that its toxicity has been reported in animals and humans due to direct and indirect exposure. Our study aimed to assess hepatotoxic effects of Tebuconazole at subacute doses in rats. Methods: Tebuconazole was administered by oral gavage at doses of 6, 12, 25, 50, and 100 mg/kg daily. Serum levels of ALT, AST, and ALP were determined. Histopathol...

We propose a new approach to understand the origin of the pseudogap in the cuprates, in terms of bosonic entropy. The near-simultaneous softening of a large number of different q-bosons yields an extended range of short-range order, wherein the growth of magnetic correlations with decreasing temperature T is anomalously slow. These entropic effects cause the spectral weight associated with the ...
