Echicetin coated polystyrene beads: a novel tool to investigate GPIb-specific platelet activation and aggregation. [PDF]

open access: yesPLoS ONE, 2014
von Willebrand factor/ristocetin (vWF/R) induces GPIb-dependent platelet agglutination and activation of αIIbβ3 integrin, which also binds vWF. These conditions make it difficult to investigate GPIb-specific signaling pathways in washed platelets.

Investigation on the Controllable Synthesis of Colorized and Magnetic Polystyrene Beads With Millimeter Size via In Situ Suspension Polymerization [PDF]

open access: yesFrontiers in Chemistry, 2022
A series of colorized and magnetic polystyrene/Fe3O4 (PS/Fe3O4) composite beads with millimeter size are successfully synthesized by introducing hydrophobic Fe3O4via in situ suspension polymerization of styrene for the first time.

Emission fluxes of styrene monomers and other chemicals for products containing expanded polystyrene beads [PDF]

open access: yesPLoS ONE, 2020
Styrene in indoor air can adversely affect human health. In this study, styrene monomer and other chemical emission fluxes for products containing expanded polystyrene beads (pillows, cushions, and soft toys) were measured at various temperatures to ...

Viscoelastic characteristics of pentane-swollen polystyrene beads [PDF]

open access: yesJournal of Applied Polymer Science, 1999
Expansion of pentane-swollen polystyrene beads was followed at and above the glass transition by using a very simple optical technique. Measurements allowed a suitable determination of the glass transition temperature and of the viscoelastic characteristics of the pentane-plasticized polystyrene chains inside the beads, at different pentane contents ...

Optical probing of local membrane potential with fluorescent polystyrene beads. [PDF]

open access: yesBiophys Rep (N Y), 2021
Abstract Studying the electrical activity in single cells and in local circuits of excitable cells, like neurons, requires an easy to use and high throughput methodology that enables the measurement of membrane potential. Studying the electrical properties in particular sub-compartments of neurons, or in a specific type of neurons ...

Time-resolved transcriptomics of haemocyte discrimination between challenges by nematodes and inert material in the oriental armyworm Mythimna separata [PDF]

open access: yesFrontiers in Immunology
IntroductionInsects defend against large metazoan parasites such as nematodes through haemocyte-mediated encapsulation, but how haemocytes respond to living parasites remains poorly understood.

The internal dose makes the poison: higher internalization of polystyrene particles induce increased perturbation of macrophages

open access: yesFrontiers in Immunology, 2023
Plastics are emerging pollutants of great concern. Macroplastics released in the environment degrade into microplastics and nanoplastics. Because of their small size, these micro and nano plastic particles can enter the food chain and contaminate humans ...

Accumulation and transfer of polystyrene microplastics in Solanum nigrum seedlings [PDF]

open access: yesPeerJ, 2023
Microplastic (MP) pollution is lately receiving increasing attention owing to its harmful impact on terrestrial ecosystems. In this microcosm study, we assessed the uptake and transfer of MPs in Solanum nigrum seedlings exposed to 50 mg L–1 of 0.2-µm ...
