The Trypanosoma cruzi Protein TcHTE Is Critical for Heme Uptake
(Public Library of Science, 2016-01)
Trypanosoma cruzi, the etiological agent of Chagas' disease, presents nutritional requirements for several metabolites. It requires heme for the biosynthesis of several heme-proteins involved in essential metabolic pathways ...
Revisão das espécies nominais do gênero Proloricaria Isbrücker, 2001 (Siluriformes: Loricariidae, Loricariinae): um caso de aplicação de taxonomia integrativa
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosCiências Biológicas - CB, 2023-03-20)
The catfishes of the Loricariinae subfamily inhabit the substrate environments of South
American rivers and are distinguished from the rest of the Loricariidae family by having a long,
depressed caudal peduncle and the ...
Demographic processes in the montane Atlantic rainforest: Molecular and cytogenetic evidence from the endemic frog Proceratophrys boiei
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012-03)
Historical climatic refugia predict genetic diversity in lowland endemics of the Brazilian Atlantic rainforest. Yet, available data reveal distinct biological responses to the Last Glacial Maximum (LGM) conditions across ...
New pelomedusoid turtles from the late Palaeocene Cerrej?on Formation of Colombia and their implications for phylogeny and body size evolution
Pelomedusoides comprises five moderate-sized extant genera with an entirely Southern Hemisphere distribution, but the fossil record of these turtles reveals a great diversity of extinct taxa, documents several instances ...
An update of Africanization in honey bee (Apis mellifera) populations in Buenos Aires, Argentina
(International Bee Research Association, 2018-10)
European and African honey bee populations have been separated and influenced by different environments. Furthermore, Apis mellifera is the only species of honey bees that evolved in Europe, the Middle East, and Africa, ...
The aquatic and littoral forms of the Patagonian frog Atelognathus patagonicus (Batrachylinae): new molecular evidence
(Magnolia Press, 2011-12)
Atelognathus patagonicus is one of the eight species included in the Patagonian genus Atelognathus, an endemic frog occurring in the system of endorheic basaltic lagoons of the Laguna Blanca National Park (PNLB), Neuquén, ...
A New Species of Histiotus Gervais 1856 (Chiroptera, Vespertilionidae), from the Pacific Coast of Northern Peru
(American Museum of Natural History, 2021-10)
The Pacific coastal desert of Peru harbors a unique bat fauna, including narrowly endemictaxa adapted to arid environments. This region was also the setting where several pre-Incan civilizations flourished. The Moche culture ...
A molecular perspective on the phylogeny of the Hyla pulchella species group (Anura, Hylidae)
(Academic Press Inc Elsevier Science, 2004-09)
A molecular phylogenetic analysis of the Hyla pulchella species group was performed to test its monophyly, explore the interrelationships of its species, and evaluate the validity of the taxa that were considered subspecies ...
Processes that drive the population structuring of Jenynsia lineata (Cyprinidontiformes, Anablepidae) in the La Plata Basin
(John Wiley & Sons Ltd, 2021-05)
1. The distribution of genetic diversity across a species distribution range is rarelyhomogeneous, as the genetic structure among populations is related to the degreeof isolation among them, such as isolation by distance, ...
Oxidative stress generated by irradiation of a zinc(II) phthalocyanine induces a dual apoptotic and necrotic response in melanoma cells
(Springer, 2019-01)
Melanoma is an aggressive form of skin carcinoma, highly resistant to traditional therapies. Photodynamic therapy (PDT) is a non-invasive therapeutic procedure that can exert a selective cytotoxic activity toward malignant ...
