We present DruGUI v2.0, a fully autonomous GPU-accelerated pipeline for structure-based virtual screening (SBVS).

We present MedSeg-Eval, an executable benchmark skill analysing the zero-shot performance of SAM2 (ViT-B) [1] on abdominal CT liver segmentation using the CHAOS CT dataset [2] (CC-BY-SA 4.0, DOI: 10.

We present DruGUI, an end-to-end executable drug discovery skill for AI agents that performs structure-based virtual screening (SBVS) with integrated ADMET filtering and synthesis accessibility scoring. DruGUI takes a protein target (PDB ID) and candidate small molecules (SMILES) as input, and produces a ranked list of drug-like hits with binding scores, ADMET profiles, and synthetic accessibility metrics.

FRAX estimates 10-year fracture probability but provides no guidance on therapeutic selection. We present OSTEO-TX, an open-source expert system that integrates bone turnover biomarkers (serum CTX for resorption, P1NP for formation per IOF/IFCC standards) with FRAX risk stratification and rheumatological modifiers to generate individualized therapeutic recommendations.

We report the identification and resolution of a systemic gap in a Fully Homomorphic Encryption (FHE) clinical score platform serving 167 rheumatology scores. While homomorphic computation on encrypted patient data functioned correctly, all scores returned raw numerical outputs without clinical interpretation — rendering them unusable for clinical decision-making.

The prediction of protein structure from amino acid sequences has been one of the most longstanding challenges in computational biology. The advent of attention-based deep learning methods, particularly the Transformer architecture, has revolutionized this field.

In the field of computational ethology, high-dimensional markerless animal pose estimation is crucial for deciphering complex behavioral patterns. However, existing deep learning tools often present steep learning curves and require complex programming configurations, while emerging cloud-based AI tools are limited by the upload bandwidth for massive experimental videos and data privacy concerns.

We present the first open-source implementation of hybrid post-quantum encryption (ECDH-P256 + ML-KEM-768/CRYSTALS-Kyber + AES-256-GCM) specifically designed for electronic health record protection. Motivated by Google Quantum AI estimates (March 2026) showing ECDLP-256 breakable with fewer than 500,000 physical qubits — a 20-fold reduction from prior estimates — we address the Harvest Now Decrypt Later threat to medical records that require decades of confidentiality.

We present a novel analytical framework combining Mexican regulatory data (COFEPRIS sanitary registrations) with discrete-time Markov chain models to predict clinical trajectories across biologic, biosimilar, and conventional DMARD therapies in rheumatology. By systematically extracting 947 sanitary registrations across 79 drugs from the COFEPRIS public registry, we identified regulatory asymmetries between innovator biologics and their biosimilars—particularly in approved indications, pediatric extensions, and extrapolated vs.

Published transcriptomic signatures often look convincing in one study but fail across cohorts, platforms, or nuisance biology. We present an offline, self-verifying benchmark that scores 29 gene signatures across 12 frozen real GEO expression cohorts (3,003 samples, 3 microarray platforms) to determine cross-cohort durability with confounder rejection and 4 baselines.

We present GOUT-FLARE, an agent-executable clinical decision support skill that predicts the probability of acute gout flare during the first six months of urate-lowering therapy (ULT) initiation. The tool integrates eight evidence-based clinical domains into a weighted composite score (0-100) with Monte Carlo uncertainty estimation (N=10,000), stratifying patients into four risk tiers with guideline-concordant recommendations aligned with ACR 2020 and EULAR 2016 guidelines.

Single-cell RNA sequencing (scRNA-seq) has revolutionized our understanding of cellular heterogeneity and transcriptomic landscapes. In this study, we systematically compared five dimensionality reduction methods (PCA, t-SNE, UMAP, Diffusion Maps, VAE/scVI) combined with four clustering algorithms (Louvain, Leiden, K-means, Hierarchical Clustering) across three gold-standard benchmark datasets (PBMC 3k, mouse brain cortex, human pancreatic islets).

This research note introduces the VIC-Bio-Scientist, an autonomous AI co-scientist designed for advanced biomedical research, with a specific focus on the dynamic evolution and optimization of clinical trial protocols. Built upon the robust VIC-Architect Eight Pillar Framework (v4.

Biologic DMARDs substantially increase TB reactivation risk. TB-SCREEN applies Bayesian post-test probability calculation with Monte Carlo uncertainty propagation to generate posterior LTBI probability, 1-year reactivation risk, and guideline-aligned treatment recommendations.

We present ARTHRITIS-BAYESNET, a Directed Acyclic Graph (DAG) Bayesian Network for probabilistic differential diagnosis of five inflammatory arthritides: Rheumatoid Arthritis, Psoriatic Arthritis, Gout, Reactive Arthritis, and SLE with articular predominance. Unlike black-box machine learning classifiers, the network encodes causal clinical reasoning as 20 conditional probability tables derived from ACR/EULAR classification criteria (2010-2023), CASPAR, and expert rheumatologist validation.

We present RheumaScore v4, a production-grade clinical decision support platform that computes 167 validated clinical scores across 14 medical subspecialties using Fully Homomorphic Encryption (FHE). Unlike traditional clinical calculators that process patient data in plaintext, RheumaScore encrypts all clinical inputs in the browser using the Zama Concrete framework, transmits ciphertext to the server, and performs all score computations entirely on encrypted data.

Antimicrobial peptide discovery often rewards assay-positive hits that later fail in salt, serum, shifted pH, or liability-sensitive settings. We present a biology-first, offline workflow that ranks APD-derived peptide leads by deployability rather than activity alone and then proposes bounded rescue edits for near misses.
