background: the association between hepatitis b virus (hbv) mutations and hepatocarcinogenesis were reported in the literature. preference for g over c in the leading dna strand has been reported to account for the asymmetry in nucleotide (nt) composition. the aim of this study was to analyze the complete genome sequence and compositional asymmetry of hbv in different stages of hepatitis b. met...

Microsatellites or simple sequence repeats (SSRs) are very effective molecular markers in population genetics, genome mapping, taxonomic study and other large-scale studies. Variation in number of tandem repeats within microsatellite refers to simple sequence length polymorphism (SSLP); but there are a few studies that are showed SSRs replication slippage may be occurred during in vitro amplifi...

introduction: glycoprotein b (gb) is the major antigen for induction of humoral responses against human cytomegalovirus (hcmv) making it an attractive candidate for immune prophylaxis. in the present study, the humoral immune response of balb/c mice to a truncated hcmv gb protein fused with gfp was evaluated. methods: the truncated gb coding sequence was synthesized and cloned in pegfpn1 eukary...

sarcocystis is a genus of cyst-forming parasites infecting both animals and human. this study aimed to isolate coccidian tissue cysts from muscle of infected animals by a simple method in addition to molecular identification of sarcocystis cruzi from the samples. the samples were obtained from commercial source in babol, northern iran. five grams of calf muscle was cut into 2-3 pieces in 30 ml ...

Abstract To protect the images and provide a more secure cipher image, DNA encoding is crucial in image encryption. Applying single, easily detectable coding rule to during has no impact on encryption model's security level. Therefore, using various rules while applying dynamic DNA-coding techniques have emerged strengthen improve of its security. This study integrates method with an model. The...

trichophyton rubrum (t. rubrum) is an anthropophilic dermatophyte that is distributed worldwide and causes common cutaneous disease such as mycosis. although several properties of this fungus have been investigated so far, however a few studies were carried out in the field of molecular biology of this fungus. in the present study we tried to identify its molecular characterization of the goano...

Abstract Arsenic (As) contamination in groundwater presents a major health and environmental concern. As is found two oxidation states most chemical tests for inorganic arsenic are focused on As(III), few have been developed As(V). We the simple analytical method determining As(V) concentrations using CeO2NPs fluorescein (FAM)-labeled DNA. Prior to sample measurements, we investigated key opera...
