Kinetic characterization and molecular modeling of trehalose-6-phosphate phosphatase from Anopheles gambiae and expressed in Pichia pastoris
Trehalose-6-phosphate phosphatase (TPP) is one of the primary enzymes involved in the synthesis of trehalose, the main sugar found in insect hemolymph. In the present study, we report for the first time heterologous expression in Pichia pastoris, characterization and homology modeling of TPP from Anopheles gambiae mosquito. Purified TPP recombinant exhibited a molecular weight of approximately 36 kDa with optimum pH of...

Leaf conditioning of Brazilian Cerrado species for DNA microextraction
Proper conditioning of leaf tissues in collection expeditions can affect the quantity and quality of DNA in the extraction process. The aim of this work was to define a method of preserving foliar tissue suitable for obtaining DNA from Brazilian Cerrado trees. Young leaves of species (Mangaba and Baru) were collected and conditioned in five different treatments during a period of six days. Genomic DNA was obtained using...

Effect of Moringa oleifera leaf extract on the haematological and serum biochemistry of rabbits reared in a semi-humid environment
This research is aimed at improving the productive and pathological picture of rabbits reared in a semi-humid environment using Moringa oleifera leaf extract (MOLE). Twenty four mixed- breed rabbits, having an average weight of 700g, were used in this study. They were randomly divided into four equal treatments (6 rabbits each) and gavaged with various concentrations of MOLE. Treatment 1 (control) was given 0ml MOLE/kg...

Heavy metal contamination in soils from a municipal landfill, surrounded by banana plantation in the eastern flank of Mount Cameroon
Municipal solid waste generated in our cities, with an unprecedented population growth, has resulted in degrading environmental quality, thus a major problem for policy makers. The extent of Pb, Cu, Zn, Cd, Hg and Zn contamination in soils of the studied area, where vegetables were grown, using metal contamination factor (CF) and pollution load index were assessed. The concentrations of heavy metals studied were in the...

Improvement of color and increase in anthocyanin content of ‘Niagara Rosada’ grapes with application of abscisic acid
This study aimed to assess the application effect of abscisic acid (S-ABA) on color, and total anthocyanin and phenolic compound contents of the ‘Niagara Rosada’ grapes. The experiment was carried out in a commercial vineyard located in Jales, SP, Brazil, during 2014/2015. The randomized block design was used with four treatments and five replications. The treatments consisted of applying different...

DEXseq and Cuffdiff approaches weighing differential spliced genes exons modulation in estrogen receptor β (Erβ) breast cancer cells
While the alternative transcription and splicing mechanisms have long been known for some genes like oncogenes, their prevalence in almost all multi-exon genes has been recently realized with the increasing application of high-throughput experimental methods, named Next Generation RNA Sequencing (NGS). Henceforth, understanding the regulation of these processes in comparisons between cell types and cancer requests,...

Production potential and chemical composition of elephant grass (Pennisetum purpureum Schum.) at different ages for energy purposes
The elephant grass has gained prominence as one of the main forage species used for biomass production. Therefore, the aim of this study was to identify elephant grass genotypes with high energy biomass production potential by evaluating morpho-agronomic and biomass quality. The following traits were evaluated in this study: dry matter yield (DMY), percentage of whole-plant dry matter (%DM), percentage of neutral...
