Diamondoids are cage-like saturated hydrocarbons consisting of fused cyclohexane rings. The Diamondoids family of compounds is one of the best candidates for molecular building blocks (MBBs) in nanotechnology to construct organic nanostructures compared to other MBBs known so far. The challenge is to find a route for self-assembly of these cage hydrocarbons and their applications in the bottom-...

background and aims: influenza (flu) is a respiratory infection in mammals and birds. it is caused by an rna virus in the family orthomyxoviridae. the virus is divided into three main types. influenza virus type a is found in a wide variety of bird and mammal species and can undergo major shifts in immunological properties. hemagglutinin (ha) is an important influenza virus surface antigen that...

colorectal cancer (crc) is one of the most common forms of cancers in the world and is curable if diagnosed at the early stage. analysis of dna extracted from stool specimens is a recent advantage to cancer diagnostics. many protocols have been recommended for dna extraction from stool, and almost allof them are difficult and time consuming, dealing with high amount of toxic materials like phen...

background: despite echinococcus granulosus , there are merely two old reports of e. multilocularis in-fection among iranian canids of moghan plain, the only area known endemic for the species. we detected specific dna markers in fecal samples by pcr (copro-pcr) for differential diagnosis of echinococcus species in living canids. methods: totally 144 fecal samples from domestic dogs, red foxes ...

in order to shed more light on the effect of peripheral groups of porphyrin core intophysicochemical properties and dna binding behavior of porphyrins, we have chosen toinvestigate solution properties and calf thymus dna binding behavior of meso-tetrakis (4-nbenzyl-pyridyl) porphyrin (tbzpyp) and its mn (iii), co (iii), ni (ii) and cu (ii) complexesderivatives have been studied in thermodynamic...
