Divergent Regioselective Synthesis of Functionalized 1,2,3-1H-Triazoles from Nitriles and Arylazides Under Metal-Free and/or Solvent-Free Conditions.

Highly selective and divergent syntheses, which are crucial in both organic synthesis and medicinal chemistry, involve significant advancements in compound accessibility. By modifying α-cyano esters into α-cyano ketones, the synthesis pathway broadens to include a diverse range of 4-CN, 5-amino, and 5-arylamino derivatives of 1,2,3-triazoles, which are achieved notably through the Dimroth rearrangement. This versatility extends further with the potential for a triple cascade reaction, leading to the production of carboximidamide compounds, which are facilitated by the Cornforth rearrangement.

Diflubenzuron larvicide auto-dissemination: A modeling study.

Proposing substitutes for Pyriproxyfen (PPF) in the auto-dissemination strategy is essential to ensure the continuity of the strategy in the field, especially in the case of the emergence of populations resistant to this larvicide. One possible substitute among the compounds already in use in Brazil is the larvicide Diflubenzuron (DFB). The equation that defines the proportion of oviposition sites (habitats) contaminated by the auto-dissemination strategy was modified to account for the number of visits required to reach the necessary concentration of DFB for contamination, considering scenarios with varying numbers of oviposition sites and mosquito densities.

Linking avian malaria parasitemia estimates from quantitative PCR and microscopy reveals new infection patterns in Hawai'i.

Plasmodium parasites infect thousands of species and provide an exceptional system for studying host-pathogen dynamics, especially for multi-host pathogens. However, understanding these interactions requires an accurate assay of infection. Assessing Plasmodium infections using microscopy on blood smears often misses infections with low parasitemias (the fractions of cells infected), and biases in malaria prevalence estimates will differ among hosts that differ in mean parasitemias.
