Current desires of conspecific observers affect cache-protection strategies in California scrub-jays and Eurasian jays [PDF]

, 2017
Many corvid species accurately remember the locations where they have seen others cache food, allowing them to pilfer these caches efficiently once the cachers have left the scene [1] .

Novel Bioconjugate Materials: Synthesis, Characterization and Medical Applications

Advanced Healthcare Materials, EarlyView.
This review discusses the bioconjugation of novel materials grouped under “biological”, “hybrid” and “synthetic” categories. Medical applications ranging from cancer therapy and diagnostics to optogenetics and tissue engineering are explored, and conjugation trends are highlighted as a general guide. The review concludes with a comparison of techniques

Wolbachia-induced cytoplasmic incompatibility is associated with decreased Hira expression in male Drosophila. [PDF]

PLoS ONE, 2011
BACKGROUND: Wolbachia are obligate endosymbiotic bacteria that infect numerous species of arthropods and nematodes. Wolbachia can induce several reproductive phenotypes in their insect hosts including feminization, male-killing, parthenogenesis and ...

A Wolbachia triple-strain infection generates self-incompatibility in Aedes albopictus and transmission instability in Aedes aegypti. [PDF]

, 2018
BACKGROUND: Artificially-introduced transinfections of the intracellular bacterium Wolbachia pipientis have the potential to reduce the vectorial capacity of mosquito populations for viruses such as dengue and chikungunya. Aedes albopictus has two native

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

Advanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.

Wolbachia infections in native and introduced populations of fire ants (Solenopsis spp.) [PDF]

, 2000
Wolbachia are cytoplasmically inherited bacteria that induce a variety of effects with fitness consequences on host arthropods, including cytoplasmic incompatibility, parthenogenesis, male-killing and feminization.

Does a parthenogenesis-inducing Wolbachia induce vestigial cytoplasmic incompatibility? [PDF]

Naturwissenschaften, 2011
Wolbachia is a maternally inherited bacterium that manipulates the reproduction of its host. Recent studies have shown that male-killing strains can induce cytoplasmic incompatibility (CI) when introgressed into a resistant host. Phylogenetic studies suggest that transitions between CI and other Wolbachia phenotypes have also occurred frequently ...

Engineering Extracellular Microenvironments: The Impact of Fibrous Materials on Cell Behavior

Advanced Healthcare Materials, EarlyView.
Fibrous structures are key elements of the native extracellular matrix and crucial for directing cell behavior. This review discusses how fiber properties such as composition, diameter, and alignment affect cell responses in 2D and 3D systems. Strategies for integrating fibrous cues into engineered tissues are highlighted, and future directions for ...

Wolbachia-mediated reproductive manipulation in rice planthoppers

Crop Health
Rice planthoppers, including brown (Nilaparvata lugens), small brown (Laodelphax striatellus), and white-backed (Sogatella furcifera) planthoppers, are major agricultural pests in China and severely affect rice production and food security.

Comparative Genomics of a Parthenogenesis-Inducing Wolbachia Symbiont. [PDF]

, 2016
Wolbachia is an intracellular symbiont of invertebrates responsible for inducing a wide variety of phenotypes in its host. These host-Wolbachia relationships span the continuum from reproductive parasitism to obligate mutualism, and provide a unique ...
