Variation in the chloroplast DNA sequence is useful for plant phylogenetic studies. However, the number of variable sequences provided by chloroplast DNA for suggested genes or genomic regions in plant phylogenetic analyses is often inadequate. To identify conserved regions that can be used to design primers and amplify variab.. Read More»

We report two similarly affected cousins (children of monozygotic twin sisters) with phenotypic features consistent with 9p deletion syndrome, including dysmorphic craniofacial features (trigonocephaly, midface hypoplasia, upward-slanting palpebral fissures and long philtrum), intellectual disability and disorders of sex devel..

Parapiptadenia rigida, locally known as angico, is a tropical tree common in the semideciduous Brazilian forest. Its wood is naturally resistant to insect attack and is useful for construction. Extracts from the tree have medicinal properties. We characterized nine microsatellite loci for P. rigida. Thirty-five alleles were detected in a sample of 45 indi.. Read More»

The association between the NAD(P)H: quinone oxidoreductase 1 (NQO1) gene C609T polymorphism and gastric cancer has been widely evaluated, yet with conflicting results. Data were available from seven study populations involving 2600 subjects. Overall, comparison of alleles 609T and 609C indicated a significantly increased risk (46%) for gastric cancer (95..

The purpose of this study was to screen for genes that were differentially expressed between a human gastric carcinoma cell line (HGC-27) and their tumor spheres, using the gene chip technique. The HGC-27 cells and tumor sphere cells were cultured in vitro in a sterile environment. Total RNA was extracted from both sa.. Read More»

DNA repair proteins maintain DNA integrity; polymorphisms in genes coding for these proteins can increase susceptibility to colorectal cancer (CRC) development. We analyzed a possible association of MLH1 -93G>A and 655A>G and XRCC1 Arg194Trp and Arg399Gln polymorphisms with CRC in Mexican patients. Genomic DNA samples were obtained from peripheral b..

The objective of this study was to evaluate the role of human activity factors, such as environmental contamination and habitat changes, as drivers for changing the physiological, biochemical, and genetic diversity of Geoffroy’s side-necked turtle populations in one of the most impacted watersheds in southeastern Brazil. The impact of chemical and o.. Read More»

Leishmaniasis is a parasitic infectious disease with global repercussions. American cutaneous leishmaniasis (ACL) is endemic in southern Brazil and its pathogenesis varies according to parasite species, immune response, and host genetics. In terms of immunogenetics, many host genes, including HLA (human leukocyte antigen), cou.. Read More»

The hybrid giant tiger grouper is a fish that has considerable commercial value and has become increasingly important for aquaculture in South East Asia since 2008. In order to prevent any reduction in genetic diversity in hybrid grouper as a result of aquaculture, we have identified 21 microsatellite markers that can be used .. Read More»

We estimated the genetic distances among 10 spring wheat genotypes based on pedigree data, morphological traits and AFLP markers, used individually and combined with morphological traits, to find the best predictors of general- and specific-combining abilities among parental genotypes. Ten wheat parents were crossed in a diallel form, disregarding recipro.. Read More»
