At present, the use of nanoparticles is a controversial topic, especially when analyzing their effects in human tissues. Nanoparticles (NPs) can cause oxidative stress by increasing membrane lipids peroxidation and reactive oxygen species, and decreasing intracellular glutathione. Oxidative stress plays an important role in ce.. Read More»

SYBR safeTM efficiently replaces ethidium bromide in Aspergillus fumigatus gene disruption
Authors: H.M.S. Canela, L.A. Takami and M.E.S. Ferreira
Invasive aspergillosis is a disease responsible for high mortality rates, caused mainly by Aspergillus fumigatus. The available drugs are limited and this disease continues to occur at an unacceptable frequency. Gene disruption is essential in the search for new drug targets. An efficient protocol for A. fumigatus gene disrupt.. Read More»

Comparison of winter and summer canola (Brassica napus) genotypes in Turkey
Authors: E. Maltas H.C. Vural
We examined genetic relationships between canola (Brassica napus) genotypes cultivated in winter and spring in Turkey. Genomic DNA was isolated from the seeds by two modified CTAB protocols: EZ1 nucleic acid isolation method and a commercial kit (Dneasy Plant Mini Kit, Qiagen). Diversity and genetic relationships in the genotypes were analyzed with RAPD m.. Read More»

XRCC1 rs25487 polymorphism is associated with lung cancer risk in epidemiologically susceptible Chinese people
Authors: X. Wang, K.W. Ma, Y.G. Zhao, G.J. Wang, W. Li
Base excision repair (BER) plays an important role in maintaining genome integrity and anti-cancer drug resistance. Single nucleotide polymorphisms (SNPs) in BER genes were detected in 500 lung cancer patients and 500 cancer-free controls. A logistic regression model was applied to analyze the relationship between lung ca.. Read More»

Analysis of the mitochondrial COI gene and its informative potential for evolutionary inferences in the families Coreidae and Pentatomidae (Heteroptera)
Authors: H.V. Souza1, S.R.C. Marchesin2 and M.M. Itoyama1
The mitochondrial cytochrome oxidase subunit 1 (COI) gene is one of the most popular markers used for molecular systematics. Fragments of this gene are often used to infer phylogenies, particularly the region near the 5'-end, which is used by the DNA Barcoding Consortium. With a growing number of sequences being deposited in the DNA barcoding database, th.. Read More»

Coconut genome size determined by flow cytometry: Tall versus Dwarf types
Authors: M. Freitas Neto1, T.N.S. Pereira1, I.G.C. Geronimo1, A.O.N. Azevedo1,S.R.R. Ramos2 and M.G. Pereira1
Coconuts (Cocos nucifera L.) are tropical palm trees that are classified into Tall and Dwarf types based on height, and both types are diploid (2n = 2x = 32 chromosomes). The reproduction mode is autogamous for Dwarf types and allogamous for Tall types. One hypothesis for the origin of the Dwarf coconut suggests that it is a Tall variant that resulted fro.. Read More»

Genetic diversity of Burkholderia (Proteobacteria) species from the Caatinga and Atlantic rainforest biomes in Bahia, Brazil
Authors: A.C. Santini H.R.M. Santos E. Gross R.X. Corr�ªa
The genus Burkholderia (Ã?²-Proteobacteria) currently comprises more than 60 species, including parasites, symbionts and free-living organisms. Several new species of Burkholderia have recently been described showing a great diversity of phenotypes. We examined the diversity of Burkholderia spp in environmental samples collected from Caatinga and Atlantic r.. Read More»

Molecular identification of the traditional herbal medicines, Arisaematis Rhizoma and Pinelliae Tuber, and common adulterants via universal DNA barcode sequences
Authors: B.C. Moon, W.J. Kim, Y. Ji, Y.M. Lee, Y.M. Kang and G. Choi
Methods to identify Pinelliae Tuber and Arisaematis Rhizoma are required because of frequent reciprocal substitution between these two herbal medicines and the existence of several closely related plant materials. As a result of the morphological similarity of dried tubers, correct discrimination of authentic herbal medicines is difficult by conventional .. Read More»

Evaluation of methods of DNA extraction from Staphylococcus aureus in milk for use in real-time PCR
Authors: A.G. Dibbern, B.G. Botaro, M.P. Viziack, L.F.P. Silva and M.V. Santos
The aim of this study was to evaluate the repeatability and performance of 4 methods of extracting DNA from Staphylococcus aureus (SAU) and the gene encoding bovine mitochondrial cytochrome B (BMCB) in milk samples from cows with subclinical mastitis for use in amplification by real-time polymerase chain reaction. Two milk samples were obtained from cows .. Read More»

Genetic diversity of Saccharum officinarum accessions in Pakistan as revealed by random amplified polymorphic DNA
Authors: F.A. Khan, A. Khan, F.M. Azhar and S. Rauf
Genetic diversity of 20 sugarcane accessions in Pakistan was studied using 21 random amplified polymorphic DNA markers. The mean genetic distance between the cultivars was 39.03%, demonstrating that a large part of the genome is similar among the accessions. This probably arises from a lack of parental diversity, with few clon.. Read More»
