A huge coronary artery aneurysm in osteogenesis imperfecta: a case report.

Osteogenesis imperfecta (OI) as an inherited connective tissue disorder can affect all tissues that contains type I collagen. Well-known cardiac complications of this disease such as aortic root dilatation, aortic regurgitation and mitral valve prolapse have been rarely reported in the literature. Coronary artery aneurysm is a rare cardiac complication in OI, as reported in a 19 year old female presenting with myocardial infarction and hypotension.

Investigation of the efficacy of a biogeneric recombinant human erythropoietin alfa in the correction of post-transplantation anemia: a randomized comparative trial with Eprex.

Background: Recombinant human erythropoietin is the cornerstone of therapy for anemia associated with chronic kidney disease or renal transplantation. However, it is not affordable and available for all patients. The present randomized double-blind trial compared the efficacy and safety of a biogeneric erythropoietin, Epolyrec, with the original product, Eprex, in correcting post-transplantation anemia (PTA).

Evaluation of a community-based drowning prevention programme in northern Islamic Republic of Iran.

Near field of strongly coupled plasmons: uncovering dark modes.

Strongly coupled plasmons in a system of individual gold nanoparticles placed at subnanometer distance to a gold film (nanoparticle-on-plane, NPOP) are investigated using two complementary single particle spectroscopy techniques. Optical scattering spectroscopy exclusively detects plasmon modes that couple to the far field via their dipole moment (bright modes). By using photoemission electron microscopy (PEEM), we detect in the identical NPOPs near-field modes that do not couple to the scattered far field (dark modes) and are characterized by a strongly enhanced nonlinear electron emission process.

Epidemiology of burns in Iran during the last decade (2000-2010): review of literature and methodological considerations.

The approach to burn prevention, to be effective in a particular area, should be based on sound knowledge of etiological patterns of burns injuries and must take into account the geographical variations and socioeconomic differences in burn epidemiology. Although many articles are published on burns epidemiology in Iran, a holistic view of burn epidemiology in Iran is not well presented in literature. In this study, a wide literature review was made on articles published regarding burns injuries in Iran.

Recurrence of primary hyperoxaluria after kidney transplantation.

Primary hyperoxaluria is a genetic disorder in glyoxylate metabolism that leads to systemic overproduction of oxalate. Functional deficiency of alanine-glyoxylate aminotransferase in this disease leads to recurrent nephrolithiasis, nephrocalcinosis, systemic oxalosis, and kidney failure. We present a young woman with end-stage renal disease who received a kidney allograft and experienced early graft failure presumed to be an acute rejection.

Plasmon hybridization and strong near-field enhancements in opposing nanocrescent dimers with tunable resonances.

A novel dimer nanostructure architecture featuring two symmetrically arranged crescents with opposing, nanometer-sized tips in close proximity is fabricated by colloidal lithography. This structure exhibits a strong and highly localized electrical near-field in the gap region between the tips. The close proximity of the tips in the nanocrescent dimers leads to a strong coupling process which generates new hybrid plasmon modes with different optical resonances.
