influenza a virus is now considered to be widespread in poultry and has demonstrated the ability to infect humans in iran. for laboratory diagnosis of these respiratory viruses, it is essential to have rapid methods, able to detect viruses in early stages of the infection in clinical specimens. the real-time reverse-transcription polymerase chain reaction n (rrt-pcr) assay has been established ...

late-onset alzheimer's disease (load) is a neurodegenerative disorder and the most common form of dementia affecting people over 65 years old. alzheimer’s disease is a complex disease with multi-factorial etiology. inflammation has been approved to have an important role in the pathogenesis of alzheimer’s disease (ad). tnf-a is a main pro-inflammatory cytokine that plays an essential role in in...

the present study was undertaken to screen the soil samples collected in iran for the presence of the bacillus subtilis lipase a gene. the bacterial colonies obtained from the collected soil samples were examined by physical appearance, biochemical tests and  the polymerase chain reaction (pcr). only four colonies were identified as putative b. subtilis strains and all contained the lipase a ge...

We study the kth largest value, M (k) n , among the oospring of particles in the nth generation of a branching process with immigration. In particular, M (1) n gives the oospring of the most proliic particle in that generation. Limit theorems for M (k) n and EM (k) n are proved. The results are obtained by combining the extreme value theory methods and known results for the behavior of the popu...

Pecci-Quinn (PQ) symmetry breaking by perturbative dynamics would suffer from a hierarchy problem, just like the electroweak in standard model. The of axion, associated with PQ breaking, also involve triviality problem. We provide paradigm to resolve those two problems potentially existing scenario, keeping successful axion relaxation for QCD strong CP phase. proposed theory includes an axicolo...

PURPOSE In this manuscript we report one pediatric surgeon's experience in childhood inguinal hernia repair. METHODS From 2005 to 2008, 402 children with inguinal hernias were operated on by one surgeon. A retrospective survey of their charts was carried out to evaluate the demographics and clinical aspects of these patients. RESULTS The ages ranged from 20 days to 16 years with a male-to-f...
