To further help democratize tPOD research, here we outline 'TPD-seq' which links microplate-based exposure methods involving cell lines for human (Caco-2, Hep G2) and environmental (rainbow trout RTgill-W1) health, with a commercially available RNA-seq kit, with a cloud-based bioinformatics tool (ExpressAnalyst.ca). We applied the TPD-seq workflow to...

Addressing child undernutrition may improve vaccine efficacy and reduce the burden of vaccine-preventable diseases. Thu, 12 Dec 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: Revisiting the functional annotation of TriTryp using sequence similarity tools https://pubmed.ncbi.nlm.nih.gov/39640808/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241207012056&v=2.18.0.post9+e462414 Trypanosomatids are the causative agents of deadly diseases in humans and livestock. Given the high phylogenetic distance of trypanosomatids from model organisms, these organisms have ample unannotated genes. Manual functional annotation is time-consuming, highlighting the importance of automated functional annotation tools. The development of automated functional tools is a hot research topic, and multiple tools have been developed for the task. PANNZER2 is an automated functional annotation...

Qualitative findings highlighted the importance of stakeholder engagement. Telehealth tools have potential for the remote follow-up of acute health conditions. Wed, 04 Dec 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: Use of <em>Caenorhabditis elegans</em> to Unravel the Tripartite Interaction of Kynurenine Pathway, UPR<sup>mt</sup> and Microbiome in Parkinson's Disease https://pubmed.ncbi.nlm.nih.gov/39595547/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241128004242&v=2.18.0.post9+e462414 The model organism Caenorhabditis elegans and its relationship with the gut microbiome are gaining traction, especially for the study of neurodegenerative diseases such as Parkinson's Disease (PD). Gut microbes are known to be able to alter kynurenine metabolites in the host, directly influencing innate immunity in C. elegans. While the mitochondrial unfolded protein response (UPR^(mt)) was first characterized in C. elegans in 2007, its relevance in host-microbiome interactions has only become... Wed, 27 Nov 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: A Reproducible Protocol for the Isolation of Malaria-Derived Extracellular Vesicles by Differential Centrifugation https://pubmed.ncbi.nlm.nih.gov/39584985/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241126041309&v=2.18.0.post9+e462414 Over the last few decades, malaria-derived extracellular vesicles (EVs) have gained increasing interest due to their role in disease pathophysiology and parasite biology. Unlike other EV research fields, the isolation of malaria EVs is not standardized, hampering inter-study comparisons. Most malaria EV studies isolate vesicles by the "gold-standard" technique of differential (ultra)centrifugation (DC). Here, we describe in detail an optimized and reproducible protocol for the isolation of... Mon, 25 Nov 2024 06:00:00 -0500 Recent publications from TDC/Clinical Epidemiology authors: Continuous characterisation of exacerbation pathophysiology using wearable technologies in free-living outpatients with COPD: a prospective observational cohort study https://pubmed.ncbi.nlm.nih.gov/39579617/?utm_source=Other&utm_medium=rss&utm_campaign=pubmed-2&utm_content=1zSVwQViw4htk0ptJE-rdb4g98Hn0Vy51ceCnixBnFkL6ILsbf&fc=20201106102241&ff=20241125020112&v=2.18.0.post9+e462414 BACKGROUND: The most recent exacerbation of COPD (ECOPD) classification criteria relies in part on changes in respiratory rate (RR), heart rate (HR) and oxygen saturation (SpO(2)). Despite this paradigm shift, a thorough understanding of exacerbation patterns is still lacking, as is the identification of physiological exacerbation biomarkers.

In this Review, we systematically synthesize publications and submissions to regulatory agencies describing technologies that provide phenotypic AST faster than conventional methods. We characterize over ninety technologies in terms of...
