background: bone morphogenetic protein 2 (bmp- 2) belongs to the tgf-β superfamily of proteins and plays an important role in the development of bone and cartilage. bmp- 2 is also associated with maintenance and repair of damaged bone. recombinant human bone morphogenetic protein 2 (rhbmp- 2) is now produced by genetic engineering techniques and used in treatment of thin bone fractures in the j...
according to recent achievements in nano technology we can see its effects in different engineering fields. in nano manufacture process the first essential step is modeling coordinately in order to make it available different software are developing for this propose. in this paper nano modeling for two papers is developed first understanding structure in nano and micro size and second simulati...
hydrogen is considered as a unique choice for future world’s resources. the important parameter in the process of hydrogen production is the value of reduction potential for the used catalyst, in direct contact with consumed energy in process. the application of computational methods to design and modify molecular catalysts is highly regarded. this study sought to explore density functional the...

objective(s):from the ancient era, emergence of agriculture in the connecting region of mesopotamia and the iranian plateau at the foothills of the zagros mountains, made iranian gene pool as an important source of populating the region. it has differentiated the population spread and different language groups. in order to trace the maternal genetic affinity between iranians and other populatio...
conclusions overall, we found that obi was rare, but that the prevalence of obi was slightly higher in jiangsu than in other areas of china. methods all donor samples were routinely screened by double enzyme-linked immunosorbent assay (elisa) for hepatitis c virus (hcv), hepatitis b virus (hbv), human immunodeficiency virus (hiv), treponema pallidum (tp), and alanine aminotransferase (alt). sin...
conclusions the inter- and intra-hospital dissemination of resistant clones is a matter of concern and is an indicator of the level of the improvement and surveillance of standard hygiene, particularly disinfection and hand washing before and after contact with patients. given the emergence of mbl-producing strains, surveillance has become an important procedure to control the transmission of r...
background: the phylogenetic location of chinese spirometra sparganum isolates remains unclear. the aim of this study was to explore the phylogenetic location of the spirometra sparganum isolates from china. methods: the 28s ribosomal dna (rdna) d1 sequences of 14 spirometra sparganum isolates collected from thirteen locations in china were analyzed by using neighbor-joining (nj), maximum parsi...
background: canine visceral leishmaniasis (cvl) is a systemic disease with a high mortality rate, caused by a diphasic protozoan parasite, leishmania infantum/chagasi in the world. the objective of the present study was to determine the presence of cvl in the city and suburbs of kerman, using a range of serological, histopathological and molecular methods. methods: blood samples were taken from...
background molecular farming is the production of important recombinant proteins in transgenic organisms on an agricultural scale. interferons are proteins with antiviral and antitumor activities and can be used for viral infections and cancers treatments. objectives this study reports the transformation of inf α2b gene in tobacco plant for the first time in iran. materials and methods interfer...
