More than 98% of a typical vertebrate genome does not code for proteins. Although non-coding regions are sprinkled with short (<200 bp) islands of evolutionarily conserved sequences, the function of most of these unannotated conserved islands remains unknown. One possibility is that unannotated conserved islands could encode non-coding RNAs (ncRNAs); alternatively, unannotated conserved islands...
Background and Aims: Influenza virus nucleoprotein (NP) has the capacity to be used as subunit vaccine, but little is known about the impact of different cultures on its structure. In the present study we aimed to evaluate and compare the Isoelectric focusing (IEF) property of extracted viral nucleoproteins derived from Madin Darby canine kidney (MDCK) cell line and embryonated chicken eggs (EC...
Little is known about how genetic variation contributes to neuroanatomical variability, and whether particular genomic regions comprising genes or evolutionarily conserved elements are enriched for effects that influence brain morphology. Here, we examine brain imaging and single-nucleotide polymorphisms (SNPs) data from ∼2,700 individuals. We show that a substantial proportion of variation in ...
Background: Argas persicus has a great importance for health and veterinary, it can transmit many infectious agents such as Borrelia anserina (avian spirochetosis) and Aegyptianella pullorum. Distinguishing Argasidae due to close morphological relationship is difficult. OBJECTIVES: In the present study, we performed molecular analyses based on PCR and sequencing of Amplicon derived from 16S rRN...
The variable regions of five human immunoglobulin heavy chains of the V(H)III subgroup have been totally sequenced. Three of the heavy chains belonged to the IgG class and two to the IgA class. Examination of these sequences, and comparison with additional published heavy chain sequences, showed that a total of four hypervariable regions is characteristic of human heavy chain variable regions. ...
Degenerate primers-based polymerase chain reaction (PCR) are commonly used for isolation of unidentified gene sequences in related organisms. For designing the degenerate primers, we propose the use of local alignment search method for searching the conserved regions long enough to design an acceptable primer pair. To test this method, a WD40 repeat-containing domain protein from Beauveria bass...
the identification of the efficiency of some mtdna genes of mus musculus species complex (house mouse) for biosystematics research was studied in this approach. recent studies have made use of different mitochondrial genes including nadh dehydrogenase genes, cytochrome b gene, cytochrome oxidase genes, d-loop region and whole mtdna genome to study the house mouse species. usage of each of these...
ticks are an important problem among zoonotic diseases. main veterinary species of hard ticks are: hyalomma sp. boophilus sp and rhipicephalus sp. among them hyalomma sp. have widespread distribution in iran and middle east. the best method to control hyalomma sp. is immunological one, by using antigens, which causes immunologic and physiologic reactions in host.bm86 is one of the best antigens...
Evolutionarily conserved noncoding genomic sequences represent a potentially rich source for the discovery of gene regulatory regions. However, detecting and visualizing compositionally similar cis-element clusters in the context of conserved sequences is challenging. We have explored potential solutions and developed an algorithm and visualization method that combines the results of conserved ...
