13. New insights into the detection and molecular characterization of Cryptosporidium with emphasis in Brazilian studies: a review
ABSTRACT Cryptosporidium spp. is a pathogenic protozoan present in the gastrointestinal tract of several hosts. This protozoan was originally classified as within the Coccidia Class and has recently been reclassified to gregarine based on studies that observed the evolutionary phases from the process of excision and sequencing of the 18S rRNA gene. Molecular

14. DNA de alta qualidade isolado a partir do córtex de Euterpe edulis Mart. (Arecaceae)
Resumo Euterpe edulis (palmiteiro-juçara) é uma arbórea de porte alto que ocorre naturalmente em florestas da Mata Atlântica e Cerrado. Por estas características é difícil coletar folhas jovens, sadias e frescas para obtenção de DNA genômico de boa qualidade para a espécie, necessárias para estudos de biologia molecular. Visando facilitar coletas

15. Isolation, cultivation and immunofluorescence characterization of lamellar keratinocytes from equine hoof by using explants
RESUMO: É notória a importância do casco na saúde dos equinos, mas o conhecimento em nível celular é pouco entendido. Estudos envolvendo o cultivo de queratinócitos equinos são escassos. Sabe-se que o desenvolvimento de cultivos de queratinócitos in vitro é uma condição para estudos sobre a biologia molecular, crescimento e diferenciação celula

16. Integrated analysis of the critical region 5p15.3–p15.2 associated with cri-du-chat syndrome
Abstract Cri-du-chat syndrome (CdCs) is one of the most common contiguous gene syndromes, with an incidence of 1:15,000 to 1:50,000 live births. To better understand the etiology of CdCs at the molecular level, we investigated theprotein–protein interaction (PPI) network within the critical chromosomal region 5p15.3–p15.2 associated with CdCs using syste

17. INFORMACIÓN BIOLÓGICA: ¿LA TEORÍA DE LA INFORMACIÓN ATACA DE NUEVO?
Abstract The philosophy of biology literature offers several arguments aimed at showing that information theory is conceptually unsuited to capture the informational talk in molecular biology. Such arguments led to the consensus that, if the informational talk in biology can be defended and explained at all, we need a different strategy. The debate, in fact,

18. RM1 Semiempirical Model: Chemistry, Pharmaceutical Research, Molecular Biology and Materials Science
In this review, we show improvements to the semiempirical quantum chemical method RM1 and present a wide range of its applications as reported by researchers of various areas, such as theoretical, organic, physical, analytical, and inorganic chemistry, as well as their interfaces with medicinal chemistry, biology, and materials science. Success of RM1 is see

19. Crane flies (Diptera, Tipuloidea) from southern Neotropical salt marshes: survey with DNA barcoding
ABSTRACT Crane flies are the most diverse group within Diptera, but they are rarely studied in coastal ecosystems. Considering the scarcity of information on the biology and ecology of this group in the Neotropics, and the sparse literature available for taxonomic identification, we developed a descriptive checklist that incorporates morphology and DNA barco

20. What is known about Tritrichomonas foetus infection in cats?
Resumo Tritrichomonas foetus é um parasito que foi identificado definitivamente como agente de tricomoníase, caracterizada por diarreia crônica. T. foetus coloniza porções do intestino grosso dos felinos e se manifesta como uma diarreia crônica e recorrente, com muco e sangue, geralmente irresponsiva às drogas comumente usadas no tratamento. O diagnó

21. Efficacy of sertraline against Trypanosoma cruzi: an in vitro and in silico study
Abstract Background: Drug repurposing has been an interesting and cost-effective approach, especially for neglected diseases, such as Chagas disease. Methods: In this work, we studied the activity of the antidepressant drug sertraline against Trypanosoma cruzi trypomastigotes and intracellular amastigotes of the Y and Tulahuen strains, and investigated its

22. A review of the systematic biology of fossil and living bony-tongue fishes, Osteoglossomorpha (Actinopterygii: Teleostei)
RESUMO Os peixes da Superordem Osteoglossomorpha têm sido foco de inúmeros estudos sobre a morfologia, sistemática e evolução, particularmente devido à sua posição basal dentre os peixes teleósteos. Fazem parte deste grupo os “mooneyes” (Hiodontidae), “knifefishes” (Notopteridae), o “abu” (Gymnarchidae), peixes-elefante (Mormyridae), aru

23. Global panorama of studies about freshwater oligochaetes: main trends and gaps
Abstract Freshwater oligochaetes have been studied over the years in a wide range of habitats around the world. To analyse the data published about freshwater oligochaetes in the 31 year period between 1985 and 2015, we searched for documents in the ISI Web of Science, Scopus and SciELO databases. A total of 979 works were evaluated from 184 periodicals. The

24. Fatal case of spotted fever in a patient from Northeastern Brazil
ABSTRACT Spotted fevers are diseases caused by bacterial agents belonging to the spotted-fever (SF) group of the genus Rickettsia. The first documented case of SF in Pernambuco State, Northeast Brazil, was reported here. Also, it is the first case described of fatal SF in Northeast region of Brazil. The patient was a resident of Arcoverde municipality and th
