b a ckground: cutaneous leishmaniasis due to leishmania major is a serious and increasing problem affecting manyrural areas of 17 out of 31 provinces in iran. little is known about sand fly fauna and leishmaniases in eastern iran and no study has been carried out in sarbisheh county. the aim of this study was to determine sand flies composi- tion and probable leishmania infection to find the pr...

Genetic Analysis of D-Loop Region Mitochondrial DNA Sequence in Iranian Patients with Familial Adenomatous Polyposis (FAP): A Case-Control Study

background and objectives: dna ladder contains dna fragments of different length but with known size, used to determine the size of unknown dna molecules. different dna ladders are available for expected dna length. conserved sequences were selected for design of primers to generate dna fragments of known specific size. materials and methods: in this study, we describe a method by which dna lad...

In recent years, the advancement of digital technology has led to an increase in data transmission on the Internet. Security of images is one of the biggest concern of many researchers. Therefore, numerous algorithms have been presented for image encryption. An efficient encryption algorithm should have high security and low search time along with high complexity.DNA encryption is one of the fa...

This paper proposes two methods for the compression of biological sequences like DNA/RNA. Although many algorithms both lossy and lossless exist in literature, they vary by ratio. Moreover, existing show different ratios inputs. Our proposed exhibit nearly constant ratio which helps us to know amount storage needed advance. For first method, we call it CryptoCompress, use a blend Cryptographic ...

Background: Birds are considered as a reservoir for pathogenic and non-pathogenic fungi. Pigeon droppings have the potential for spreading these fungi to the environment. Cryptococcus species are important fungi associated with pigeon droppings. In this regard, there are many types of yeast associated with guano that is important for human and animal health. Ai...

Current models of DNA origami folding can explain the yield assembly process and isomerization structure upon application mechanical forces. Nevertheless, role sequence...

in this study the genetic diversity of wild caspian trout (salmo trutta caspius) in the sardabroud and astara rivers was evaluated using d- loop region sequencing. for this purpose, 35 specimens of adult caspian brown trout were collected from these rivers in the mazandarn and gilan provinces in fall and winter 2011. approximately 3-5 g of soft and fresh fin tissue was isolated and fixed in eth...

aspartic proteases are a relatively small group of enzymes which express in various nematodes including onchocerca volvulus. an estimation of the gene copy number corresponding to the ov7a clone, which contains a cdna insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of o. volvulus, was made by slot blot analysis in a closely related species o. gibsonig...
