Is Nematocharax (Actinopterygii, Characiformes) a monotypic fish genus?
(Canadian Science Publishing, Nrc Research Press, 2016-10-01)
The combination of DNA barcodes and geometric morphometrics is useful to discriminate taxonomically controversial species, providing more precise estimates of biodiversity. Therefore, our goal was to assess the genetic and ...
Primitive to non-primitive BCH codes: An instantaneous path shifting scheme for data transmission
(World Scientific Publ Co Pte Ltd, 2018-12-01)
In this paper, we present constructions of primitive and non-primitive BCH codes using monoid rings over the local ring Z(2m), with m >= 1. We show that there exist two sequences {C-bjn}(j >= 1). and {C'(bjn)}(j >= 1) of ...
Development of a loop-mediated isothermal amplification (LAMP) assay for the detection of Anaplasma marginale
(Springer, 2019-01-01)
Parasitemia generated by Anaplasma marginale causes significant losses in the cattle industry. A major constraint to the effective control and management of anaplasmosis in livestock is the lack of a rapid and reliable ...
Towards a phylogenetic classification of the Ocotea complex (Lauraceae): classification principles and reinstatement of Mespilodaphne
(Oxford Univ Press, 2019-05-01)
The large genus Ocotea (c. 400 species) has been known to be paraphyletic with respect to most other Neotropical genera of Lauraceae for almost 20 years, but a phylogenetic classification has not yet been proposed. Here ...
Heterologous expression, purification and biochemical characterization of a new xylanase from Myceliophthora heterothallica F.2.1.4
(2019-06-15)
Myceliophthora heterothallica is a thermophilic fungus potentially relevant for the production of enzymes involved in the degradation of plant biomass. A xylanase encoding gene of this species was identified by means of ...
The copper-inducible copAB operon in Xanthomonas citri subsp. citri is regulated at transcriptional and translational levels
(2019-03-01)
Upstream open reading frames (ORFs) are frequently found in the 5¢-flanking regions of genes and may have a regulatory role in gene expression. A small ORF (named cohL here) was identified upstream from the copAB copper ...
Production of milk peptides with antimicrobial and antioxidant properties through fungal proteases
(2019-04-25)
Bioactive peptides can provide health benefits due to different mechanisms. The aims of the present study are to produce bioactive peptides from bovine and goat milk subjected to the proteolytic activity of Aspergillus ...
Molecular characterization and identification of Hepatozoon species Miller, 1908 (Apicomplexa: Adeleina: Hepatozoidae) in captive snakes from Brazil
(2018-12-01)
Species of Hepatozoon are parasites frequently recorded in snakes. The species identification of this genus was based mostly on the gametocyte morphology and morphometric calculations. For more reliable results, molecular ...
Synthesis, Racemic X-ray Crystallographic, and Permeability Studies of Bioactive Orbitides from Jatropha Species
(2018-11-26)
Orbitides are small cyclic peptides with a diverse range of therapeutic bioactivities. They are produced by many plant species, including those of the Jatropha genus. Here, the objective was to provide new structural ...
Genetic Diversity of ‘Candidatus Liberibacter asiaticus’ Revealed by Short Tandem Repeats and Prophage Typing Indicates Population Homogeneity in Brazil
(2019-01-01)
‘Candidatus Liberibacter asiaticus’ is the most common huanglongbing-associated bacteria, being present in Asia, South, Central, and North America. Genomic approaches enabled sequencing of ‘Ca. L. asiaticus’ genomes, ...
