The critical micelle concentration (CMC) is a crucial parameter in understanding the self-assembly behavior of surfactants. In this study, we combine simulation and experiment to demonstrate the predictive capability of molecularly informed field theories in estimating the CMC of biologically based protein surfactants. Our simulation approach combines the relative entropy coarse-graining of small-scale atomistic simulations with large-scale field-theoretic simulations, allowing us to efficiently compute the free energy of micelle formation necessary for the CMC calculation while preserving chemistry-specific information about the underlying surfactant building blocks. We apply this methodology to a unique intrinsically disordered protein platform capable of a wide variety of tailored sequences that enable tunable micelle self-assembly. The computational predictions of the CMC closely match experimental measurements, demonstrating the potential of molecularly informed field theories as a valuable tool to investigate self-assembly in bio-based macromolecules systematically.

Despite promising results in using deep learning to infer genetic features from histological whole-slide images (WSIs), no prior studies have specifically applied these methods to lung adenocarcinomas from subjects who have never smoked tobacco (NS-LUAD) - a molecularly and histologically distinct subset of lung cancer. Existing models have focused on LUAD from predominantly smoker populations, with limited molecular scope and variable performance. Here, we propose a customized deep convolutional neural network based on ResNet50 architecture, optimized for multilabel classification for NS-LUAD, enabling simultaneous prediction of 16 molecular alterations from a single H&E-stained WSI.

Conventional miRNA-based diagnostic methods often treat all biomarkers equally, overlooking the fact that each miRNA contributes differently to disease classification. This differential diagnostic importance is captured by the concept of Cancerous Diagnostic Valence (CDV)-a metric that quantifies both the direction (oncogenic or protective) and magnitude of each miRNA's association with cancer. Here, we introduce a polymerase-based DNA molecular computing system that directly encodes and integrates CDVs to perform weighted molecular classification of non-small cell lung cancer (NSCLC).

The tropical rainforest is one of the most biodiverse, productive, and complex terrestrial biomes in the world. Human-induced environmental changes increase the emergence and spread of vector-borne diseases. Ticks (Acari: Ixodida) are medically and veterinary important arthropods that infest a wide range of vertebrate hosts, including humans, and act as vectors of diverse pathogens, such as bacteria of the genus Rickettsia.

Alcohol seeking during abstinence is mediated in part by strong associations between the pharmacological effects of alcohol and the environment within which alcohol is administered. The amygdala, particularly the basolateral amygdala (BLA), is a key neural substrate of environmental cue and reward associations since it is involved in associative learning and memory recall. However, we still lack a clear understanding of how alcohol affects the activity of BLA neurons, which may encode information that drives environmental cue-dependent, alcohol-related behaviors.

Background: Ovarian cancer (OC) is the fifth leading cause of cancer-related death among women, with High-Grade Serous Ovarian Carcinoma (HGSC) representing the most aggressive and prevalent subtype. Despite promising results in other malignancies, immune checkpoint blockade has shown limited efficacy in HGSC, highlighting the need for alternative immunotherapeutic targets.
Methods: We conducted an integrated analysis combining multiparametric flow cytometry, RNA sequencing, multiplex immunohistochemistry, and functional assays to characterize NK cells isolated from peripheral blood, peritoneal fluid, primary tumor tissue, and metastases in 60 HGSC patients.
