The influence of biological rhythms on host–parasite interactions [PDF]

open access: yes, 2015
Biological rhythms, from circadian control of cellular processes to annual cycles in life history, are a main structural element of biology. Biological rhythms are considered adaptive because they enable organisms to partition activities to cope with ...

Characterization and Variability Analysis of Volatile Metabolites From Acer saccharum Leaves From Québec Region

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Volatile secondary metabolites in plants can serve as valuable biomarkers for the plant's health, stress response, and pest or disease detection. We have investigated the volatilome of Acer saccharum (sugar maple) leaves using two complementary extraction techniques: headspace‐solid phase micro‐extraction coupled with gas chromatography‐mass ...

Large deviations for infectious diseases models [PDF]

open access: yesarXiv, 2016
We establish large deviation estimates for Poisson driven models of infectious disease, and apply those estimates to the time of exit from the basin of attraction of an endemic equilibrium. We apply our results to the classical SIRS model.

Efficient and Rapid Arylation of NH₂‐Unprotected Bromobisindole Ethanamines via Suzuki‐Miyaura Coupling: Generating New Leads Against Leishmania

open access: yesChemistry – A European Journal, EarlyView.
A library of novel bisindole derivatives was synthesized through an optimized rapid Suzuki‐Miyaura coupling reaction, utilizing NH2‐unprotected bromobisindole ethanamines and boronic acids with yields up to 93%. The compounds were screened for their activity against L. infantum promastigotes.
