Molecular characterization of D variants in Brazilian blood donors and their association with RhCE and Duffy phenotypes

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Serological classification of RhD‐negative and weak D is often insufficient in admixed populations, where diverse RHD variants have clinical implications. In Brazil's highly admixed population, RhD interpretation and donor–recipient matching are particularly challenging.

Sedentary ageing remodels the structure–function relationships that underlie calcium signalling at super‐resolution scales in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Illustration of calcium spark function and ryanodine receptor (RyR) structure within a sedentary model of ageing. Upon sympathetic stimulation from 1 µM isoprenaline a linear response to calcium spark morphology occurred, accompanied by a biphasic progression of RyR remodelling across age.

Toward Metabolomics Analyses With Combined Capillary Vibrating Sharp‐Edge Spray Ionization and Atmospheric Pressure Chemical Ionization

Rapid Communications in Mass Spectrometry, Volume 40, Issue 17, 15 September 2026.
ABSTRACT Rationale The varied properties of metabolomics components dictate the tools used in mass spectrometry (MS) characterization including the selection of the ionization source. However, the ionization of select compounds limits characterization efficiency.

Optimization of antibody binding by adjusting thermodynamic stability during the maturation of antibody affinities

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Somatic mutations and antibody clone selection occur in B‐cell hyper‐evolution over extremely brief periods of time. Herein, we developed a technique for antibody screening by immunizing alpacas with antigens and observing antibody sequence transitions over time, a method we named Tracking the Evolution of Antibodies over time.

European Society of Contact Dermatitis Guideline for Diagnostic Patch Testing—Recommendations on Best Practice (Update 2026)

Contact Dermatitis, Volume 95, Issue 3, Page 237-275, September 2026.
ABSTRACT The present guideline updates the initial ESCD patch testing guideline, summarizing all aspects of patch testing for the diagnosis of contact allergy in patients suspected of suffering, or having been suffering, from allergic contact dermatitis or other delayed‐type hypersensitivity skin and mucosal conditions.

Structural and Functional Insights Into (S)‐5′‐C‐Guanidinopropyl Uridine‐Modified Oligonucleotides With 2′‐O‐Methyl and 2′‐Fluoro Substitutions for RNAi Therapeutics

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Novel (S)‐5′‐guanidinopropyl uridine analogs bearing 2′‐O‐methyl or 2′‐fluoro substitutions enhance nuclease resistance and mismatch discrimination while preserving A‐form RNA structure and potent RNAi activity. These modifications provide a promising strategy for improving the stability, specificity, and therapeutic potential of siRNA‐based medicines.

ZDHHC17‐Mediated CDK4 Palmitoylation Drives Cell Cycle Progression and Orchestrates Cancer Immune Surveillance

Advanced Science, Volume 13, Issue 44, 7 August 2026.
ZDHHC17 palmitoylates CDK4, which together with TRAF6‐mediated ubiquitination, drives cell cycle progression and immune surveillance, revealing a rational combination of CDK4 inhibitors with immune checkpoint blockers for ZDHHC17‐driven cancers. ABSTRACT Uncontrolled cell cycle progression is a hallmark of cancer, tightly regulated by both intrinsic ...

GK PUA Domain Modulates Cables, Cooperativity, and Proline Feedback

Aggregate, Volume 7, Issue 8, August 2026.
EcGK tetramers hierarchically assemble into metabolic filaments and bundle into metabolic cables. Upon substrate binding, this dynamic equilibrium shifts from inactive cables to active tetramers to drive catalysis; meanwhile the inhibitor proline stabilizes an X‐shaped conformation, redirecting assembly toward filaments to enable efficient feedback ...
