Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

open access: yesExperimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Effects of OTT services on consumer's willingness to pay for optical fiber broadband connection in Thailand

open access: yes, 2016
Over-the-top (OTT) media and communications services are shifting internet consumption towards the increase of traffic over the internet. Since FTTH provides the highest capacity and speed of the broadband service, this paper attempts to examine the ...

Sodium thiosulfate treatment rescues hyperglycaemia‐induced pronephros damage in zebrafish by upregulating nitric oxide signalling

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sodium thiosulfate (STS) rescues the pronephros phenotype of pdx1 morphants through compensatory upregulation of nitric oxide (NO) metabolism. Zebrafish larvae injected with a control morpholino show the typical pronephros structure at 48 h post‐fertilization (hpf) with and without STS treatment.

The spread of non‐native species

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Hyperaldosteronism in Mice Lacking the Distal Polybasic Tract of the γ‐Subunit of the Epithelial Sodium Channel During Sodium Restriction

open access: yesActa Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aims The epithelial sodium channel ENaC consists of the subunits α, β, and γ and is activated at an individual channel level by proteolytic processing. Murine γENaC contains a distal polybasic tract 186RKRK mediating proteolytic ENaC activation by serine proteases in vitro.

Nucleomorph phylogenomics suggests a deep and ancient origin of cryptophyte plastids within Rhodophyta

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3103-3113, June 2026.
Summary The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal nuclei. The genes present on nucleomorph genomes can be used for phylogenomic reconstruction in order to unravel the ...

Dependence of Mineral Dissolution Rates on Two‐Phase Hydrodynamics in Single Pores

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Multiphase flow and mineral reactions co‐exist in many subsurface systems, and thus elucidating and quantifying the impacts of multiphase flow on mineral reaction rates are crucial. Our study established a benchmark experiment on calcite dissolution in cylindrical pores in slug flow, and performed a series of simulations using a validated pore‐
