Molecular fingerprinting of principal neurons in the rodent hippocampus: A neuroinformatics approach
Background and purpose: E. coli bacteria is detected by culture, serology and molecular methods. In molecular methods PCR products are created using little random primers. The main purpose of this research was to study the genetic diversity of Escherichia coli bacteria. Also, the propinquity of isolated bacteria with two common strains of EnteroPathogenic E. coli (St.1) and EnteroHaemorrhagic E...
In combinatorial library design and use, the conformation space of molecules can be represented using three-dimensional (3-D) pharmacophores. For large libraries of flexible molecules, the calculation of these 3-D pharmacophoric fingerprints can require examination of trillions of pharmacophores, presenting a significant practical challenge. Here we describe the mapping of this problem to the U...
Preimplantation genetic diagnosis (PGD) has experienced a considerable technical evolution since its first application in the early 1990s. The technology for single-cell genetic analysis has reached an extremely high level of accuracy and enabled the possibility of performing multiple diagnoses from one cell. Diagnosis of a monogenic disease can now be combined with aneuploidy screening, human ...
tarkhineh is one of the traditional foods in iran and a rich source of probiotic bacteria. the objective of this study was to identify the probiotic bacteria isolated from tarkhineh using 16s rrna gene sequencing and molecular typing with repetitive extragenic palindromic–pcr (rep-pcr). in total, 20 different bacteria were isolated from traditional dairy products and tarkhineh. molecular identi...
Molecular surveillance of pathogenic microbes works by genotyping isolates with DNA fingerprinting techniques and then using these genotypes to assign individuals to populations. Clonality is assumed in many fingerprinting studies, although this assumption has been shown to be false for many organisms. To accommodate recombining organisms into surveillance programs, methods using population all...
We conducted the first molecular study of tuberculosis (TB) to estimate the role of household contact and transmission from HIV-positive putative source contacts (PSCs) in a high HIV-prevalence area. TB patients in a long-term population-based study in Malawi were asked about past contact with TB. DNA fingerprinting was used to define clusters of cases with identical strains. Among 143 epidemio...
