13. Molecular detection of adulteration in commercial buffalo meat products by multiplex PCR assay
Abstract Authentication of commercial buffalo meat products has become a market concern. This study intended to develop and validate a highly species-specific multiplex PCR assay for authentication of buffalo meat products. Four pairs of species-specific primers were used to target mitochondrial cytochrome oxidase I (COI) gene. The assay generated the expec

14. Relações genéticas e taxonômicas de cinco espécies de Rallidae (Aves: Gruiformes) com base em sequências de subunidade I da citocromo oxidase mitochondrial
RESUMO. Este é o primeiro estudo para a detecção da relação genética entre Porphyrio alleni e quatro espécies de Rallidae: Fulica atra, Gallinulla angulata, Gallinulla chloropus e Porphyrio porphyrio. As seqüências de subunidade i (COI) do citocromo oxidase foram usadas como marcador efetivo neste estudo. O DNA das espécies Rallidae foi extraído,

15. The exotic jumping snail Ovachlamys fulgens (Gude, 1900) (Gastropoda: Helicarionidae) in urban areas of the Upper-Paraná Atlantic Forest
ABSTRACT The exotic land gastropod Ovachlamys fulgens (Gude, 1900), aka the jumping snail, was registered in Eldorado city, Misiones province, constituting the first documented record of that species in Argentina-and for all of South America as well. Identities of the individuals were confirmed through morphological examination, and by a DNA sequencing of th

16. A conventional PCR for differentiating common taeniid species of dogs based on in silico microsatellite analysis
ABSTRACT Canine taeniids are among the major tapeworms with remarkable medical and economic significance. Reliable diagnosis and differentiation of dog taeniids using simple and sensitive tools are of paramount importance for establishing an efficient surveillance system. Microsatellites as abundant unique tandem repeats of short DNA motifs are useful geneti

17. Genetic divergence of a newly documented population of the cecidogenous micromoth Eugnosta azapaensis Vargas & Moreira (Lepidoptera: Tortricidae) in the Atacama Desert of northern Chile
Abstract Eugnosta azapaensis Vargas and Moreira, 2015 (Lepidoptera: Tortricidae) is a micromoth native to the Atacama Desert whose larvae induce fusiform galls in shoots of Baccharis salicifolia (Ruiz & Pav.) Pers. (Asteraceae). The presence of this cecidogenous tortricid was previously recorded only from the type locality, the Azapa Valley, Arica Province,

18. Insights into the intracellular mechanisms of citronellal in Candida albicans: implications for reactive oxygen species-mediated necrosis, mitochondrial dysfunction, and DNA damage
Abstract INTRODUCTION Citronellal (Cit) possesses antifungal activity and has possible implications for reactive oxygen species (ROS) generation in Candida albicans. In this study, the effects of Cit on ROS generation and the mechanisms by which Cit exerts anti-Candida effects were examined. METHODS A 2′,7′-dichlorodihydrofluorescein diacetate assay

19. Detection of differentially methylated regions of irradiated fig tree selections
ABSTRACT Fig tree (Ficus carica L.) breeding programs using conventional methods, such as directed crosses, to obtain new cultivars, are unworkable in many countries, including Brazil. Consequently, genetic breeding through mutagenesis has emerged as an important line of research that can improve this crop, and be a significant source of information about th

20. Antioxidants in dermatology
Abstract The skin cells continuously produce, through cellular respiration, metabolic processes or under external aggressions, highly reactive molecules oxidation products, generally called free radicals. These molecules are immediately neutralized by enzymatic and non-enzymatic systems in a physiological and dynamic balance. In situations where this balance

21. Development of a real-time PCR assay for the detection of the golden mussel ( Limnoperna fortunei , Mytilidae) in environmental samples
ABSTRACT The golden mussel, Limnoperna fortunei, is among the most devastating invasive species in freshwater habitats worldwide, leading to severe environmental disturbances and economic losses. Therefore, management efforts would be greatly improved by methods that efficiently detect and quantify the abundance of the golden mussel in freshwater habitats, p

22. A new species of Parastacus Huxley, 1879 (Crustacea, Decapoda, Parastacidae) from a swamp forest in southern Brazil
Abstract In this contribution we describe a new species of burrowing crayfish of the genus Parastacus Huxley, 1879 from a swamp forest in southern Brazil and determine its conservation status. The distinction of the new species is based on morphology and the mitochondrial DNA marker 16S rRNA. The extinction risk was assessed according to the sub-criterion B1

23. Mitochondrial and Y chromosome genetic diversity in the Portuguese Lidia bovine breed
ABSTRACT A total of 80 samples were collected to analyze the mitochondrial DNA (mtDNA) and Y chromosome genetic diversity of two main Portuguese Lidia bovine populations and clarify their genetic relationships with Spanish Lidia lineages. A 521-bp D-loop fragment was sequenced in 40 animals belonging to four herds (three Brava dos Açores and one Casta Portu

24. NUEVA ESPECIE DE RANA BROMELÍCOLA DEL GÉNERO PRISTIMANTIS (AMPHIBIA: CRAUGASTORIDAE), MESETA DE LA CORDILLERA DEL CÓNDOR, ECUADOR
ABSTRACT We describe a small frog of the genus Pristimantis inhabiting bromeliads (snout-vent length 20.3-23.3 mm in females, 16.1-17.4 mm in males), from a remote sandstone plateau of the Cordillera del Condor, in southeastern Ecuador, with an altitudinal range of 2,045-2,860 m. A phylogeny based on sequences of DNA (mitochondrial and nuclear genes) support
