Title

Contrasting Patterns of DNA Damage by the Comet Assay in Four Species of the hylidae Family (Amphibia-Anura)

Abstract

Amphibians are components of many ecological communities and they can be used as indicators of environmental quality. Thus, in this study we evaluated the genome sensitivity of four species of anuran amphibians of the Hylidae family in a cattle raising area (Bela Vista de Goiás) and in a nickel area (Barro Alto) both at Goiás state, Central Brazil. The species analyzed are: Dendropsophus minutus, Hypsiboas albopunctatus, Hypsiboas paranaiba and Scinax fuscomarginatus. The comet assay was used as a biomarker to estimate DNA damage in these four Hylidae species. The genomic analyses were realized using the software "Comet Score" v1.5. An analysis of variances (ANOVA) and t-test were carried out to verify the genomic damage among and between all the four species analyzed. In the three comet assay parameters used, the species sampled from the nickel areas showed the largest stretches of DNA damage when compared to the same species sampled in the cattle raising area. So, we can suggest that all evaluated species may be used for eco-genotoxicity of aquatic environments.

Thinking Inside the Box: Drosophila F-Box Protein Models of Human Disease

Abstract

F-box proteins are diverse and essential E3 enzymes that function as compo-nents of SCF ubiquitin ligase complexes. They act as substrate specific targe-ting proteins which allow the SCF complex to selectively attach ubiquitin to multiple proteins in the cell, marking those proteins for either destruction or alternative functions. In mammals, F-box proteins are involved in pathways of growth, proliferation, circadian rhythm, cell cycle regulation, tumor suppres-sion and in many different human conditions or diseases such as muscle wasting, cancer phenotypes, Huntington and Parkinson disease.  Many F-box homologues have been identified between mammals and Drosophila melano-gaster but few have been studied comparatively between the two. In flies F-box proteins have been implicated in many of the same processes as the mammalian homologues but also in phagocytosis, wing defects and male sterility. In this review we summarize the homologous F-box proteins betwe-en mammals and flies and outline their functions both within and between species with the hope of clarifying their conserved function.  In addition, we show that many F-box proteins seem to have developed diverse or unique functions within one lineage independent of one another.

Morphometric Variation among Barred Spiny Eel, Macrognathus pancalus (Hamilton 1822), Populations from the Ganges and Brahmaputra River Basin, India by Using Geomorphometrics

Abstract

The freshwater barred spiny eel, Macrognathus pancalus is an inland telostean fish. It is found in the lentic as well as lotic environment. This model system shows phenotypic plasticity in allopatry. Here we used the landmark-based geometric morphometric methods for describing the patterns of body shape variation and shape co-variation with size among the populations of the barred spiny eel Macrognathus pancalus. We found a significant body shape variation among the populations of river basins. The principal component analysis followed by discriminate function analysis showed 99.43 % body shape variation with a cross validation of 99.4 %.

Title

In vitro Antioxidant Capacities of Star Fruit (Averrhoa carambola), an Underutilised Tropical Fruit

Abstract

Star fruit is an underutilised tropical fruit that could serves as an alternative food sources to the world. The current study was, therefore, undertaken to investigate the functional potentials of green and ripe star fruits by determin-ing its antioxidant contents and capacities. The antioxidant capacities of star fruit were increased significantly with ripening, except for the total ascorbic acid content. The ripe star fruit peel contained higher total polyphenol (98.19 g TAE/100 g FW), total flavanol (33.31 g CAE/100 g FW) and ascorbic acid contents (1.56 g AAE/100 g FW) than green star fruit peel. Ripe star fruit peel also demonstrated stronger FRAP (1.41 M FEA/100 g FW) and DPPH (75 % inhibition) values than green star fruit peel. The antioxidant capacities of peel were greater than pulp. On the basis of results obtained, the ripe star fruit is a potential source of natural antioxidants owing to its significant antioxidant activities.
