Low‐Density Lipoprotein Receptor‐Targeted Biomimetic Nanoplatform Suppresses Glioblastoma Stemness and Remodels Antitumor Immunity via Dual Metabolic Disruption

open access: yesAdvanced Science, EarlyView.
A low‐density lipoprotein receptor‐oriented biomimetic nanoplatform couples brain‐tumor delivery with a mechanistically matched regorafenib‐erythrodiol combination. Concurrent disruption of autophagic nutrient salvage and cholesterol homeostasis collapses bioenergetic and signaling support, suppresses glioblastoma stemness, and promotes immunogenic ...

Single‐Stranded Interruptions in the T7 Promoter Non‐Template Strand Exhibit Unexpected Transcription Behavior

open access: yesAngewandte Chemie, EarlyView.
DNA structures with short single‐strand gaps in the non‐template strand of the T7 promoter prevent transcription by T7 RNA polymerase. Contrary to intuition, however, transcriptional activity can be observed again when the size of the gap increases toward the transcription start site, thereby reducing the proportion of double‐stranded DNA in the ...

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Ligand‐Directed Molecular Beacons as Turn‐On Fluorescent Probes for Sensing Cell‐Surface Receptor‐Ligand Interactions

open access: yesAngewandte Chemie, EarlyView.
Multivalent, ligand‐directed molecular beacons enable fluorescence turn‐on detection of cell‐surface receptors in living cells. The probes strongly engage closely spaced membrane receptors and exhibit conformation‐dependent fluorescence enhancement at the cell surface, enabling wash‐free receptor imaging, inhibitor screening, and functional evaluation ...

Emerging Memory and Device Technologies for Hardware‐Accelerated Model Training and Inference

open access: yesAdvanced Electronic Materials, EarlyView.
This review investigates the suitability of various emerging memory technologies as compute‐in‐memory hardware for artificial intelligence (AI) applications. Distinct requirements for training‐ and inference‐centric computing are discussed, spanning device physics, materials, and system integration.

Mechanical Signatures of Nucleic Acid Trefoil Knot Topology

open access: yesAngewandte Chemie, EarlyView.
Single‐stranded DNA can be designed with sequences that self‐thread into topological knots. The exact same sequence can alternatively be turned into an unknotted pseudoknot. The topology of the resulting polymer is determined by applying force with optical tweezers, causing the pseudoknot to resolve but the knot to tighten.

Palatability of geophyte underground storage organs partially explains their depth in the Cape Floristic Region, geophyte capital of the world

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The soil depth of underground storage organs (USOs) of geophytes involves cost–benefit trade‐offs and may relate to USO age, size, and disturbances such as fire and herbivory. Yet determinants of USO depth are poorly studied. We posit that belowground mammalian predation of USOs is a selective force for the positive relationship ...

IL‐31 levels correlate with pruritus in patients with cholestatic and metabolic liver diseases and is farnesoid X receptor responsive in NASH

open access: yesHepatology, EarlyView., 2022
IL‐31 levels correlate with pruritus in patients with cholestatic and metabolic liver diseases Abstract Background and Aims Pruritus is associated with multiple liver diseases, particularly those with cholestasis, but the mechanism remains incompletely understood.

An Adult Presentation of KIF11‐Related MCLID Syndrome: Case Report and 40‐Year Follow‐Up

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic variants in KIF11 are linked to autosomal dominant syndromes with microcephaly, chorioretinopathy, lymphedema, and intellectual disability (MCLID), though adult presentations remain underreported. We report a 42‐year‐old female presenting with a de novo single‐amino acid in‐frame deletion in the KIF11 gene (c.1294_1296del; p ...
