breast carcinoma is the major cause of cancer-related death in women. the incidence of this carcinoma is rising and there are many attempts to decrease this problem. the aim of this study was detection of full-length cytokeratin 19 (ck19) mrna, in peripheral blood and tissue of breast cancer patients in early stage of cancer. in this study, rt-pcr (reverse transcriptase-polymerase chain reactio...

objectives: this current research was conducted in order to analyze the molecular characterization of isolated cryptosporidium spp. in the southwest of iran. materials and methods: in this survey, 390 fecal samples were collected from immunocompromised individuals and children under five-years-of-age. parasitic infection was evaluated using wet mount preparation, formalin ether, a modified acid...

Die Frage, wie sich die RNA als ein Träger der genetischen Information entwickelt hat, ist von grundlegender Bedeutung für unser Verständnis des Ursprungs Lebens. Das RNA-Molekül viel zu komplex, das es in einem einzigen Evolutionsschritt hat entstehen können, was darauf hindeutet, dass Proto-RNAs (erste Vorläufer RNA) gegeben haben könnte, im Laufe Zeit heutigen haben. Hier zeigen wir, Isoxazo...

It is commonly understood that RNA-binding proteins crucially determine the fate of their target RNAs. Vice versa, RNAs are becoming increasingly recognized for functions in protein regulation and dynamics RNA-protein complexes. Long non-coding emerging as potent regulators exert unknown properties moonlighting functions. A vast array RNA- protein-centric techniques have been developed identifi...

background:in the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded rna viruses from cdna or viral minigenomes. this technique has been applied to study different steps in virus replication and virus-host interactions. reverse genetics could also be implemented for design of new vaccines. the t7 rna polymerase activity as well as virus (nucleocapsi...
