Fluorescence Sensing of Anions Like Adenosine 5ʹ‐Triphosphate With pH‐Gated Porous Dye‐Loaded Cerasomes

Small, EarlyView.
The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

Environmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

VIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.

The thrombin receptor (PAR1) is associated with microtubules, mitosis and process formation in glioma cells

Heliyon
The cell surface protease-activated receptor 1 (PAR1) is overexpressed in glioblastoma multiforme (GBM). We studied the function and structure of intracellular microtubule (MT) and PAR1 in a tubulin-mediated process.

The Comet Assay for the Evaluation of Genotoxic Potential of Landfill Leachate

The Scientific World Journal, 2012
Genotoxic assessment of landfill leachate before and after biological treatment was conducted with two human cell lines (Me45 and NHDF) and Daphnia magna somatic cells. The alkali version of comet assay was used to examine genotoxicity of leachate by DNA

The Training Complex: Shattering of the Coniunctio, Boundary Violation, and Sibling Turbulence on the Horizontal Plane

Journal of Analytical Psychology, EarlyView.
Abstract This paper explores what is happening, for a trainee, when an ethical boundary violation occurs by the analyst with a fellow peer in training. I am approaching this through the Jungian concept of the alchemical vas as I attempt to make meaning of a catastrophic collapse of the analytic work.

Observations of counter-streaming ions in and around the diamagnetic cavity of comet 67P

Astronomy & Astrophysics
Context. Ion speeds at comet 67P/Churyumov-Gerasimenko significantly exceed local neutral gas speeds, a discrepancy that challenges current ion-neutral coupling models.

Two dimensional hybrid simulations of small scale obstacles in the solar wind [PDF]

The structure and dynamics of the solar wind interaction with two small scale obstacles (of the order of a pickup ion gyroradius) is examined. These are a comet, comparable to Grigg-Skjellerup, and a weakly ionospheric planet.
