Overcoming The Dyadic Default In Research On Child Development, Roman Stengelin, Patricia Kanngiesser, Sophie Milward

School of Psychology

Researchers conducting experimental work on sociocognitive development in childhood typically study one-on-one interactions. This approach aligns with the assumption that children's social cognition, motivation, and learning first emerge in dyadic interactions before scaling up to larger social ensembles. In this article, we argue that this dyadic default reflects widespread theoretical and cultural biases as well as methodological convenience, leading to an overemphasis on dyadic interactions in research on child development. Because dyadic engagements can differ qualitatively and quantitatively from those in larger social ensembles, the dyadic default may systematically skew our understanding of key areas of social development and fail …

Neuroendocrine prostate cancer (NEPC) is a highly aggressive and lethal subtype of prostate cancer (PCa) that often emerges in response to androgen receptor pathway inhibitors (ARPIs), which are widely used in treating metastatic castration-resistant and hormone-sensitive prostate cancer. The incidence of NEPC is increasing, yet effective therapeutic strategies remain limited due to an incomplete understanding of its molecular drivers. Through transcriptomic analyses of human prostate tumor samples, we identified the histone lysine demethylase KDM4A as uniquely overexpressed in human and mouse NEPC compared to prostate adenocarcinoma. Functional validation demonstrated that KDM4A is a key regulator of NEPC progression and a …

Optimising Anti-Seizure Medication Timing Using A Dynamic Network Model Of Seizure Rhythms, Jake Ahern, Udaya Seneviratne, Wendyl D’Souza, Mark J. Cook, John R. Terry

Peninsula Medical School

Epileptic seizures and interictal discharges exhibit robust circadian and multidien rhythms, yet the interaction between these biological cycles and anti-seizure medication (ASM) pharmacology remains poorly understood. Here, we present a dynamical network model that integrates rhythmic fluctuations in cortical excitability with pharmacokinetic properties of common ASMs to explore how treatment timing influences efficacy. The framework embeds a slow, rhythm-generating process directly within the governing equations, allowing seizure-like dynamics to emerge endogenously. We simulated ASMs with a range of distinct half-lives under single-daily and twice-daily dosing schedules. For the short half-life ASM, efficacy depended strongly on the phase of administration, with …
