We investigated the allelic frequencies and forensic descriptive parameters of 23 autosomal short tandem repeat loci in a randomly selected sample of 1218 unrelated healthy Uyghur individuals residing in the Xinjiang Uyghur Autonomous Region, northwest China. A total of 281 alleles at these loci were identified and their corresponding allelic frequencies ranged from 0.0004 to 0.5390. The combin...

Reticulon (RTN) genes code for a family of proteins relatively recently described in higher vertebrates. The four known mammalian paralogues (RTN1, -2, -3, and -4/Nogo) have homologous carboxyl termini with two characteristic large hydrophobic regions. Except for RTN4-A/Nogo-A, thought to be an inhibitor for neurite outgrowth, restricting the regenerative capabilities of the mammalian CNS after...

The phylogenetic information content of different developmental stages is a long-standing issue in the study of development and evolution. We performed phylogenetic analyses of 51 body segmentation genes in 12 species of Drosophila in order to investigate the impact of the mode of evolution of development on phylogeny inference. Previous studies of these genes in Drosophila using pairwise phene...

background and objectives: the escherichia coli strains are greatly important in nosocomial and community acquired infections. the aim of this study was to determine the transmission of bacterial infections using genetic analysis. materials and methods: two hundred and thirty escherichia coli strains, isolated from different clinical samples, were characterized by enterobacterial repetitive int...

Stellantchasmus falcatus is a minute intestinal fluke in the family Heterophyidae. Metacercariae, the infective stage, were reported in a marine fish, mullet Liza subviridis, and a fresh water fish, Dermogenus pusillus, in Thailand. Adults were found in chicks, rats, cats, and humans. Morphological studies were done for comparing Stellantchasmus sp. worms found in 2 different fish hosts; their ...

Background Phylogenetic relationship within different genera of Lemnoideae, a kind of small aquatic monocotyledonous plants, was not well resolved, using either morphological characters or traditional markers. Given that rich genetic information in chloroplast genome makes them particularly useful for phylogenetic studies, we used chloroplast genomes to clarify the phylogeny within Lemnoideae. ...

The CLE family (CLAVATA3/embryo surrounding region-related), a class of small secreted proteins, play important roles in plant development and stress responses. Members the have been characterized number species, including Arabidopsis rice. However, limited information is available about peptides tobacco (Nicotiana tabacum) related Nicotiana species. Here we report identification 84 members thr...
