Abstract Mycobacterium tuberculosis drug resistance (DR) challenges effective disease control. Current molecular tests examine limited numbers of mutations, and although whole genome sequencing approaches could fully characterise DR, data complexity has restricted their clinical application. A library (1,325 mutations) predictive DR for 15 anti-tuberculosis drugs was compiled validated 11 them using genomic-phenotypic from 792 strains. rapid online ‘TB-Profiler’ tool developed to report...
Approximately 10% of the Mycobacterium tuberculosis genome is made up two families genes that are poorly characterized due to their high GC content and highly repetitive nature. The PE PPE typified by conserved N-terminal domains incorporate proline-glutamate (PE) proline-proline-glutamate (PPE) signature motifs. They hypothesised be important virulence factors involved with host-pathogen interactions, but genetic variability complexity analysis means they typically disregarded in studies.To...
Nuclear receptors are ligand-inducible transcription factors that share structurally related DNA-binding (DBD) and ligand-binding (LBD) domains. Biochemical structural studies have revealed the modular nature of DBD LBD. Nevertheless, domains function in concert vivo. While high-resolution crystal structures nuclear receptor DBDs LBDs available, there no x-ray proteins containing multiple We report solution human retinoid X DBD-LBD (hRXRalphaDeltaAB) region. obtained ab initio shapes...
Genetic transformation is a powerful tool for plant breeding and genetical, physiological or biochemical research, consequently it an extremely dynamic field. Transgenic plants are commonly used to complete substitute mutants in basic helping the studies of complex biological situations such as pathogenesis process, genome organization, light reception signal transduction. In this review, recent approaches foreign gene introduction (e.g. Agrobiolistics, whole tissue electroporation, planta...
In order to develop a high-efficiency and reproducible transformation protocol for Stylosanthes guianensis we assessed the biological physical parameters affecting plant electroporation protoplasts. Energy input, as combinations of electric field strengths discharged by different capacitors, buffer DNA form were evaluated. Transformation efficiency was assayed in vivo transient reporter gene expression, using GFP-coding mgfp5 driven CaMV 35S constitutive promoter. input strength had critical...
Changes in nominal composition of the perovskite (ABO3) solid solution Ba1-x(Zr,Pr)O3-δ and adjusted firing conditions at very high temperatures were used to induce structural changes involving site redistribution frozen-in point defects, as revealed by Raman photoluminescence spectroscopies. Complementary magnetic measurements allowed quantification reduced content Pr. Weak dependence oxygen stoichiometry with temperature was obtained coulometric titration below 1000 °C, consistent a...
Members of the perovskite solid solution BaZr1–xPrxO3−δ (0.2 ≤ x 0.8) with potential high-temperature electrochemical applications were synthesized via mechanical activation and annealing at 1250 °C.
