Cryo-Em Structure Of A Photosystem I Variant Containing An Unusual Plastoquinone Derivative In Its Electron Transfer Chain, Christopher J. Gisriel, Vasily Kurashov, David F. Iwig, Brandon P. Russell, David J. Vinyard, Gary W. Brudvig, John H. Golbeck, K. V. Lakshmi

Faculty Publications

Photosystem I (PS I) is a light-driven oxidoreductase responsible for converting photons into chemical bond energy. Its application for renewable energy was revolutionized by the creation of the MenB deletion (ΔmenB) variant in the cyanobacterium Synechocystis sp. PCC 6803, in which phylloquinone is replaced by plastoquinone-9 with a low binding affinity. This permits its exchange with exogenous quinones covalently coupled to dihydrogen catalysts that bind with high affinity, thereby converting PS I into a stable solar fuel catalyst. Here, we reveal the 2.03-Å-resolution cryo-EM structure of a recent MenB variant of PS I. The quinones and their binding environment are …

“It’S Not Because They’Re Gypsy”: Practitioners Perspectives Of Gypsies, Travellers And Crime And Justice, Raegan Booth, Kirsty Koral, Kitty Lymperopoulou

School of Law, Humanities and Social Sciences

In dominant public, political and media narratives of Gypsy and Traveller communities, they have often been associated with criminality, deviance, violence, idleness and reluctance to assimilate into settled society. A discourse of othering predicated on negative stereotypes further affect their marginalisation and social exclusion. This empirical article critically examines reflections on, and responses to, these dominant narratives among practitioners who have engaged with Gypsy and Travellers operationally and strategically, in relation to crime and criminal justice. We find evidence of compliance with dominant narratives which include perceptions that deny and minimise experiences of victimisation and racism, while also suggesting a …

Maternal Low-Protein Diet Leads To Mitochondrial Dysfunction And Impaired Energy Metabolism In The Skeletal Muscle Of Male Rats, Chellakkan S Blesson, Chandra Yallampalli

Faculty, Staff and Students Publications

A prenatal low-protein (LP) diet disrupts glucose homeostasis in adult offspring. Skeletal muscles are one of the main sites of glucose clearance, and mitochondria residing in the muscle fibers are central to glucose homeostasis. Our previous studies indicated that impaired mitochondrial health is central to dysregulated glucose metabolism in the gastrocnemius muscle of the LP-programmed female rats. In addition, dysfunctional mitochondria are often an indicator of underlying irregularities in energy metabolism and metabolic inflexibility. Therefore, this study examined the mitochondrial function and metabolic flexibility in the skeletal muscles of prenatal LP-programmed adult male rats. Pregnant Wistar rats were randomly allotted …

De-Identification Is Not Enough: A Comparison Between De-Identified And Synthetic Clinical Notes

Faculty, Staff and Student Publications

For sharing privacy-sensitive data, de-identification is commonly regarded as adequate for safeguarding privacy. Synthetic data is also being considered as a privacy-preserving alternative. Recent successes with numerical and tabular data generative models and the breakthroughs in large generative language models raise the question of whether synthetically generated clinical notes could be a viable alternative to real notes for research purposes. In this work, we demonstrated that (i) de-identification of real clinical notes does not protect records against a membership inference attack, (ii) proposed a novel approach to generate synthetic clinical notes using the current state-of-the-art large language models, (iii) evaluated …
