Unveiling Lasting Impact: A Cultural‐Historical Activity Theory Perspective on Original Participants in an Afterschool STEM Club

open access: yesSchool Science and Mathematics, EarlyView.
ABSTRACT The Girls Excelling in Math and Science (GEMS) club is a long‐standing afterschool STEM program (1994–present). The study investigates the features of GEMS by exploring retrospective experiences of a group of original GEMS girls (OGGs) who attended GEMS in 1994–1995. Survey data were collected from 14 OGGs and in‐depth interview data from nine

Metaphors and the Invention of Writing

open access: yesTopics in Cognitive Science, EarlyView.
Abstract The foundation of ancient, invented writing systems lies in the predominant iconicity of their sign shapes. However, these shapes are often used not for their referential meaning but in a metaphorical way, whereby one entity stands for another.

Nitrite supplementation alleviates cerebrovascular dysfunction in chronically stressed mice, but cognitive decline remains

open access: yesExperimental Physiology, EarlyView.
Abstract This study aimed to determine whether sodium nitrite supplementation prevented chronic stress‐induced cerebrovascular dysfunction and cognitive decline. We hypothesize that nitrite supplementation will prevent the oxidative environment and cerebrovascular dysfunction associated with chronic stress and maintain cognitive health.

Elevated cortisol concentration in preterm sheep fetuses impacts heart development

open access: yesExperimental Physiology, EarlyView.
Abstract The prepartum rise in cortisol promotes cardiac development and maturation. Here, we investigated the impact of elevated circulating cortisol during mid‐late gestation on cardiac growth and metabolism in fetal sheep. Saline or cortisol (2–3 mg in 4.4 mL/24 h) was infused into the fetal jugular vein from 109 to 116 days gestation (dG, term ...

Correlated amplitudes of potentials evoked in homologous muscles by magnetic stimulation reveal positive covariation of corticospinal output

open access: yesExperimental Physiology, EarlyView.
Abstract figure There is positive covariation in the amplitudes of motor evoked potentials (MEPs) generated by (near simultaneous) stimulation of the two motor cortices. That is, larger responses to stimulation of the left motor cortex tend to be accompanied by larger responses to stimulation of the right motor cortex, and smaller responses to ...

Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This double‐blind, placebo‐controlled, randomized cross‐over trial investigated the effects of ketone monoester (KME) ingestion on resting cerebral blood flow (CBF) in young adults. We demonstrate that KME supplementation lowers CBF in a dose‐dependent manner over 2‐houra post‐ingestion, whereas CBF remained unchanged following ...
