background: tuberculosis (tb) remains as a major cause of death around the world. construction of a new vaccine against tuberculosis is an effective way to control it. several vaccines against this disease have been developed. the aim of the present study was to cloning of tb10.4 gene in pcdna3.1+ plasmid and evaluation of its expression in eukaryotic cells. methods: firstly, tb10.4 fragment wa...

cloning is a term traditionally used to describe different processes for duplicating biological material. a clone is an organism that is a genetic copy of an existing one. the use of the technique of nuclear transfer for reproduction of human beings is surrounded by strong ethical and legal concerns and controversies. some international organizations have made significant efforts to establish c...

Multiple gene silencing is being required to target and tangle metabolic pathways in eukaryotes and researchers have to develop a subtle method for construction of RNA interference (RNAi) cassettes. Although, several vectors have been developed due to different screening and cloning strategies but still some potential limitations remain to be dissolved. Here, we worked out a simple cloning stra...

With regard to human cloning or artificial human reproduction – and contrary to the opinions of Sunni scholars - Shiite thinkers have not held a unified position. After having surveyed a number of Shiite fatwas and analyses on the subject, this essay will classify them into four groups. The first group states that we are granted absolute permission to engage in human cloning; while the second g...

After the appearance of no-cloning theorem, approximate quantum cloning machines (QCMs) has become a well-studied subject in information theory. Among several measures to quantify performance QCM, single-qudit fidelity and global have been most widely used. In this paper we compute optimal for phase-covariant via semidefinite programming optimization, thereby completing remaining gap previous r...

Abstract Generation of new DNA constructs is an essential process in modern life science and biotechnology. Modular cloning systems based on Golden Gate cloning, using Type IIS restriction endonucleases, allow assembly complex multipart from reusable basic parts a rapid, reliable automation-friendly way. Many such toolkits are available, with varying degrees compatibility, most which aimed at s...

objective: leishmaniasis is caused by parasitic protozoa of the genus leishmania which in the infected host is obligate intracellular parasite. lack gene is conserved among related leishmania species. lack is the immuno-dominant antigen of l.major which is considered as the most promising molecule for a recombinant or dna vaccine against leishmaniasis. materials and methods: in this study the ...
