Open data and code are crucial to increasing transparency and reproducibility, and in building trust in scientific research. However, despite an increasing number of journals in ecology and evolutionary biology mandating for data and code to be archived alongside published articles, the amount and quality of archived data and code, and subsequent reproducibility of results, has remained worryingly low. As a result, a handful of journals have recruited dedicated data editors, whose role is to help authors increase the overall quality of archived data and code. There is, however, a general lack of consensus around what a data editor should …

Myeloid leukemia of Down syndrome (ML-DS) is a distinct form of pediatric acute myeloid leukemia (AML) that responds to reduced-intensity chemotherapy, as compared with non-DS AML that requires intensive chemotherapy and often stem cell transplant. While most patients with ML-DS have a favorable prognosis, outcomes for those with refractory or relapsed disease are dismal. Children's Oncology Group study AAML1531 introduced the use of measurable residual disease by multiparameter flow cytometry at the end of the first course of induction therapy (EOI-1 MRD) for risk stratification of treatment intensity. Of 280 patients with ML-DS who were enrolled, 41 were classified as …

Fastpca: An R Package For Fast Singular Value Decomposition., Kimberly R. Ward, Mitchell Hayes, Lauren C. Peres, Brooke L. Fridley, Steven Eschrich, Alex C. Soupir

Manuscripts, Articles, Book Chapters and Other Papers

The FastPCA package provides an interface to optimized matrix multiplication libraries (libtorch) for the purpose of singular value decomposition. Using FastPCA to perform randomized singular value decomposition (SVD, (Halko, Martinsson, & Tropp, 2011)) with the torch or pytorch backend drastically reduces the computational time compared to base R prcomp and other truncated singular value decomposition. Developed for biological data such as single-cell RNA-sequencing, spatial transcriptomics, or matrix-assisted laser desorption/ionization (MALDI imaging), FastPCA can efficiently and accurately identify the leading singular values in high-dimensional data.

Ferroptosis As A Pathological Driver In Niemann-Pick Disease Type C, Kayla Linda Sanchez

Loma Linda University Electronic Theses, Dissertations & Projects

Niemann–Pick Disease Type C (NPC) is a hereditary neurodegenerative disease characterized by selective cell vulnerability, particularly affecting cerebellar anterior Purkinje neurons. These neurons exhibit a distinctive pattern of degeneration due to the loss of NPC1 and/or NPC2 protein function, progressively extending towards posterior cerebellar regions. Historically, research has described NPC as a disorder of intracellular cholesterol handling; however, cholesterol-lowering therapies have not effectively prevented neurological deterioration, and the mechanisms underlying selective neuronal vulnerability remain unclear. Ferroptosis, previously referred to as oxytosis, is a regulated form of cell death driver by iron-induced lipid peroxidation. It has been implicated in several neurodegenerative …

Rapid and comprehensive analysis of complex proteomes across large sample sets is vital for unlocking the potential of systems biology. We present a high-throughput mass spectrometry (MS) proteomics method that integrates narrow-window data-independent acquisition (nDIA) with short-gradient micro-flow chromatography, enabling profiling of >240 samples per day. This optimized MS approach identifies 6,201 and 7,466 human proteins with 1- and 2-min gradients, respectively. As a practical application, we analyzed 507 samples composed of 13 different tissues from mice treated with the enzyme-drug L-asparaginase (ASNase) or its glutaminase-free Q59L mutant, generating a quantitative profile of 11,472 proteins following drug treatment. The MS …

Stimuli-Responsive Chemotherapy For Glioblastoma: Sequence-Dependent Synergy Of Cold Atmospheric Plasma And Ultrasound With Cationic Lipo-Doxo, Alessandro Cazzolla

Theses

Glioblastoma (GBM) is an aggressive, infiltrative astrocytic tumour in which pharmacotherapy remains constrained by the blood-brain barrier (BBB) and the heterogeneously altered blood brain tumour barrier, with additional limitations imposed by active efflux and the complexity of the tumour microenvironment. In this setting, externally addressable strategies that modulate transport and uptake at the site of disease are required. A stimuli-responsive chemotherapy platform was developed in which Lipo-DOXO was combined with two non-invasive physical modalities, low-frequency ultrasound (US) and cold atmospheric plasma (CAP), to enhance intratumoural delivery while limiting off-target effects. Liposomes were produced by thin-film hydration followed by a controlled, …

Biomineralization Of Low Temperature Plasma(Ltp) Modified Polymeric Biomaterials And Scaffolds, John Patrick Bradford

ETDs from 2020-2029

Bio-integration, specifically osseo-integration of bone implants and scaffolds, are vital for the success of implants and bone tissue engineering (BTE). Calcification can be defined as the deposition of calcium compounds as either calcium phosphate(CaP) minerals consisting of hydroxyapatite(HAP) or CaP salts. The significance of the variety of phases of CaP is that mature bone matrix is composed of 65% CaP mineral. Many investigators have attempted to model the natural matrix by producing materials containing calcium phosphate in both amorphous CaP or in the more crystalline HAP form, with biomaterials (both synthetic and biological). Biomimetic CaP formation is a sign of …

Modulation Of The Cgas-Sting Inflammation Pathway In Mouse Models Of Accelerated And Slowed Aging, Benjamin David Heckman

ETDs from 2020-2029

Chronic sterile inflammation (inflammaging) is a core pillar of aging, and the cGAS-STING innate immune pathway has emerged as a key driver of this process. However, how this pathway intersects with systemic endocrine signaling remains poorly understood. Here, we investigated the intersection of endocrine signaling and cGAS-STING activation using two complementary mouse models with opposing lifespan phenotypes: a short-lived, liver-specific glucagon receptor knockout (LKO) mouse and a long-lived growth hormone-releasing hormone knockout (GHRH-KO) mouse. We demonstrate that despite presenting with a metabolically healthy phenotype, female LKO mice exhibited a significantly reduced lifespan. We link this premature mortality to a sex …

Vaccines For Pandemics: Lessons From Covid-19 For H5n1 And Beyond, Alison Mccarthy, Michael S. Sinha

University of Chicago Legal Forum

The COVID-19 pandemic brought unprecedented challenges to vaccine development and distribution. Never before has a vaccine been developed so quickly and distributed so rapidly. But compared to past pandemics and public health crises—like polio or even the more recent H1N1 pandemic—the United States government’s COVID-19 vaccine strategy depended greatly on the private sector.

COVID-19 vaccines were credited with saving millions of lives worldwide, but private companies reaped these rewards, retained their patent rights, and profited from the vast and pressing need for their vaccines. Now, five years later, not every company views its vaccine work as a success. Financial hits …
