Heterogeneous host susceptibility enhances prevalence of mixed-genotype micro-parasite infections

open access: yes, 2011
Dose response in micro-parasite infections is usually shallower than predicted by the independent action model, which assumes that each infectious unit has a probability of infection that is independent of the presence of other infectious units. Moreover,

Floral to green: mating switches moth olfactory coding and preference [PDF]

open access: yes, 2012
Mating induces profound physiological changes in a wide range of insects, leading to behavioural adjustments to match the internal state of the animal.

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

open access: yesCytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

Navigating the future of nano‐pesticides: A perspective on design, efficacy, mechanisms, and environmental stewardship

open access: yesiMeta, EarlyView.
Nano‐pesticides are driving a paradigm shift toward sustainable plant protection. This review systematically synthesizes recent advances across four interconnected domains: (i) intelligent formulation design for targeted delivery and controlled release; (ii) interfacial behavior regulation to enhance foliar deposition; (iii) multi‐omics elucidation of ...

Midgut proteases from larval spodoptera littoralis (lepidoptera: noctutoae) [PDF]

open access: yes, 1992
The presence and properties of proteases present in larval midgut extracts from Spodoptera littoralis was investigated. Trypsin and chymotrypsin activities were found mainly in the midgut lumen while leucine aminopeptidase and dipeptidyl aminopeptidase ...

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

open access: yesJournal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...
