Online Decoding Of Rat Self-Paced Locomotion Speed From Eeg Using Recurrent Neural Networks, Alejandro De Miguel, Nelson Totah, Uri Maoz

Psychology Faculty Articles and Research

Objective. Accurate and reliable neural decoding of locomotion holds promise for advancing clinical applications such as rehabilitation and prosthetic control, as well as for understanding neural correlates of action. Recent studies have demonstrated successful decoding of locomotion kinematics across species in motorized treadmill settings. However, efforts to decode locomotion speed directly and continuously in more natural contexts—where pace is self-selected rather than externally imposed—are scarce, and those that exist generally achieve only modest accuracy and require intracranial implants. Here, we aim to decode self-paced locomotion speed non-invasively and continuously using cortex-wide electroencephalography (EEG) recordings from rats. Approach. We introduce an …

Emerging Strategies For Cardio-Renal Protection Beyond Raas Blockade: Emphasis On Non-Diabetic Ckd And Resistant Hypertension, Fahad S. Alrashidi

Saudi Medical Journal

Non-diabetic chronic kidney disease (ND-CKD) complicated by resistant hypertension remains a high-risk phenotype even when renin–angiotensin system blockade is optimized. This review synthesizes contemporary evidence for cardio-renal protection beyond traditional renin-angiotensin-aldosterone system inhibition (RAASi), with emphasis on mechanisms, clinical trial data, and pragmatic sequencing. Sodium–glucose cotransporter 2 inhibitors provide hemodynamic and tubular benefits that translate into renal and heart failure risk reduction in many patients with ND-CKD. Non-steroidal mineralocorticoid receptor antagonism (MRA) like finerenone targets inflammatory and fibrotic signaling and may add incremental benefit when potassium is proactively managed. The GLP-1 receptor agonists offer cardiometabolic advantages with emerging kidney signals, …

Faculty, Staff and Students Publications

RNA N6-methyladenosine (m6A) is a key regulator of gene expression during early embryogenesis. Using SAC-seq (m6A-selective allyl chemical labeling and sequencing), an antibody-independent m6A profiling method, we generated the first single-nucleotide-resolution m6A map of bovine oocytes and preimplantation embryos. We observed both coordinated and uncoupled relationships between m6A modification and expression of protein-coding and noncoding genes. Integrative analysis of the transcriptome, m6A epitranscriptome, and translatome revealed dynamic m6A remodeling, particularly in ribosomal protein genes. Functional interrogation of a specific m6A site within the RPL12 transcript demonstrated that loss of this modification reduces protein synthesis, disrupts translation-related gene expression, impairs zygotic …

High-Order Brain Interactions During Ketamine-Induced State Changes: A Functional Marker Of Response In Late-Life Treatment-Resistant Depression?, Krisha Shah, Rubén Herzog, Alan C Swann, Brittany O'Brien, Rahul Balakrishnan, Sanjay J Mathew, Nicholas Murphy

Faculty, Staff and Students Publications

Ketamine is a fast-acting intervention for treatment-resistant depression (TRD), yet only a subset of patients show robust clinical response, and the underlying neural mechanisms remain unclear. High-order interactions (HOI) derived from multivariate information theory provide a framework for examining nonlinear dependencies among brain regions beyond pairwise connectivity. One such metric, the O-information, captures the balance between synergistic and redundant interactions across three or more variables. In this secondary analysis of a randomized, double-blind, midazolam-controlled trial (NCT02556606), we examined EEG-derived HOI in 30 late-life veterans with TRD following a single 40-minute intravenous infusion of ketamine (0.1, 0.25, 0.5 mg/kg; n = …

Faculty, Staff and Students Publications

Early diagnosis of acute kidney injury (AKI) remains a major clinical challenge due to the delayed and insensitive nature of conventional markers such as serum creatinine. Urinary protein biomarkers, including neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (CysC), provide earlier and complementary information on kidney injury, but their clinical translation is limited by the lack of rapid, quantitative, and multiplexed point-of-care (POC) diagnostic tests. Here, we report a multiplexed plasmonic-fluor-based lateral flow assay (p-LFA) that enables sensitive, quantitative, and simultaneous detection of NGAL and CysC. By harnessing ultrabright plasmonic-fluor nanolabels and ratiometric fluorescence analysis, the p-LFA achieves picogram-per-milliliter analytical sensitivity …
