Bladder cancer; Gene polymorphism; PCR-RFLP; Toll-like receptor

In this study, the association between the 729G/C polymorphism in Toll-like receptor 4 (TLR4) and the risk of bladder cancer was investigated. A total of 376 patients with bladder cancer and 380 healthy volunteers from the Third Xiangya Hospital of Central South University (China) were enrolled in this study between January 2008 and February 2014. The TLR4-729G/C polymorphism was ... more

Coat color; meat quality; Native pig breeds; PCR-RFLP; Vertebra number

Mutations in melanocortin 1 receptor (MC1R) gene and v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) gene have been shown to affect coat color patterns in pigs. Additional functional marker genes, such as insulin like growth factor-2 (IGF2) and orphan nuclear receptor, germ cell nuclear factor (NR6A1), have been described for ... more

Goat; PCR-RFLP; Polymorphism; POU1F1 gene

As a member of the POU-domain family, the POU1F1 is a positive regulator for growth hormone, prolactin and thyroid-stimulating hormone b, by binding to target DNA promoters as a dimer in mammals. This study described the polymorphisms at the goat POU1F1-DdeI locus and analyzed the distribution of alleles in 15 indigenous Chinese goat breeds. The PCR-RFLP analysis showed ... more

Biological nitrogen fixation; Bradyrhizobium; Inoculation; PCR-RFLP; Soybean

Soybean (Glycine max) is considered one of the most economically important agricultural crops in Brazil. Due to the high protein content of its grains, this crop demands a greater amount of nitrogen (N) for production. In general, for soybean, nitrogen fertilization costs through chemical fertilizers are considered high. However, the biological nitrogen fixation ( ... more

BMP15; DRD2; marker-assisted selection; MTNR1C; PCR-RFLP; STAT5b

Signal transducers and activators of transcription (STAT5B), dopamine receptors D2 (DRD2), bone morphogenetic protein (BMP15), and melatonin receptors type C (MTNR1C) play an important role in growth and reproductive traits in chickens. We studied the 9th generation of 93 Pradu Hang Dam and 95 Chee chickens examining ... more

ERIC-PCR; MALDI-TOF; Molecular phylogeny; PCR-RFLP; Yeast identification

Pigeon droppings carry microorganisms such as Candida spp., which have high genetic variability and are the most common opportunistic pathogens in humans. There is a need to establish fast, reliable and simple laboratory methods to differentiate pathogenic from non-pathogenic yeast species in pigeon droppings, as they can be a source of contamination for ... more

Amazônia; Bayesian inference; PCR-RFLP; Stingless bees

Bees are important pollinating agents and are an integral part of food production and plant maintenance. It is useful to investigate mitochondrial polymorphisms in bees to obtain information that may be relevant to conservation strategies. We examined mitochondrial haplotypes and evaluated genetic diversity and differentiation in the native stingless bees ... more
