to determine the role of ddx3y gene in spermatogenesis and infertility in bulls, blood samples were collected from five infertile bulls (azoospermic; no sperm in the semen) at the animal breeding center in karaj, iran. the recommended human primers by eaa/eqmn were investigated using the blastn database for sts marker detection. alignment of sts marker genes with bovine genome was performed. pr...

Bioinformatics has gradually received widespread attention and shown the characteristics of a large amount calculation high complexity. Therefore, it is required to adopt computer algorithms in bioinformatics improve efficiency processing problems. Big data artificial intelligence technologies have supporting achieved certain results field bioinformatics. Introduced application basis big bioinf...

There are many challenges in the field of public health sciences. Rational decisions are required in order to treat different diseases, gain knowledge and wealth regarding research, and produce biological or synthetic products. Various advances in the basic laboratory science, computer science, and the engineering of biological production processes can help solve the occurring problems. Bioinfo...

conclusions the growth rate of information in bioinformatics databases could facilitate studies of live organisms prior to observation studies. two different protein classes could be causative agents of one disease. however, two related diseases from one disease group could consist of different protein classes. future research in the field of proteomics could allow modern insight to reshuffling...

chemodiversity in plants provides sources of great value which might be helpful for finding new leads in drug discovery programs. fabaceae as the third largest family of flowering plants was chosen to investigate its possible antifungal activity. in order to increase the effectiveness of the result, molecular similarity methods and chemical data were used. twelve plants were selected from fabac...

background: sigma factors are proteins that regulate transcription in bacteria. sigma factors can be activated in response to different environmental conditions. the rpos (rna polymerase, sigma s) gene encodes sigma-38 (σ38, or rpos), a 37.8 kda protein in pseudomonas aeruginosa (p. aeruginosa) strains. rpos is a central regulator of the general stress response and operates in both retroactive ...

κ-casein is a glycosilated protein in mammalian milk that plays an essential role in the milk micelles. control of κ-casein expression reflects this essential role, although an understanding of the mechanisms involved lags behind that of the other milk protein genes. transcriptional regulation, a first mechanism for controlling the development of organisms, is carried out by transcription facto...

advanced technologies in molecular biology and modern experimental biophysics heavily rely not only on the knowledge of structure of essential proteins but also on their structural dynamics. the function of these bimolecular systems and the pathways along which the biological phenomena take place can be determined based on the knowledge of the molecular structure and behavior. as such, the simp...

new advances in mass spectrometry-based proteomics technology are having amajor impact on our understanding of how human spermatozoa acquire their capacity for fertilization. a complete analysis of the proteins found in the human spermatozoa is essential for understanding the events leading up to, and including, fertilization and early embryo development. in this short review, we have collected...

brucellosis is a well-known infection in domestic animals which caused by brucella bacterium. due toserious economic and medical consequences of this disease, various efforts have been made to prevent theinfection through the use of recombinant vaccines based on brucella outer membrane protein (omp)antigens. the objectives of the present study were cloning, sequencing and epitope prediction of ...
