Enhancing Reaction Kinetics and Structural Control in N‐Carboxyanhydride (NCA) Polypeptide Synthesis by Structurally Tuned Azamacrocyclic Ligands

open access: yesAngewandte Chemie, EarlyView.
Azamacrocycles provide a tunable platform for rapid N‐carboxyanhydride (NCA) Ring‐Opening Polymerization (ROP). Changing the methylation pattern switches the macrocycle from an external catalyst (N14Me3) to a covalent initiator‐catalyst (IniCat, N14Me1), delivering controlled polypeptide growth under open‐vessel conditions.

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

A well‐resolved phylogeny of Cuscuta subgenus Monogynella based on data drawn from all three plant genomes

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Cuscuta (dodders) consists of ~200 species circumscribed into four subgenera (Monogynella, Cuscuta, Pachystigma, and Grammica) and is the only parasitic genus in Convolvulaceae (the morning‐glory family). This group shows a significant diversity in plastid functionality and represents a rare mixotrophic system among parasitic plants ...

Microbial‐Metabolite Signatures Are Associated With Glucocorticoid Responsiveness in Chronic Rhinosinusitis With Nasal Polyps

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) exhibit heterogeneous responses to oral glucocorticoids (GCs), but the biological basis of this variability remains unclear. Objective To identify gut microbiome‒plasma metabolomic signatures associated with GC responsiveness in CRSwNP patients and to compare their ...

T Cell‐Mediated Targeting of Interneurons in Mice Shapes Hippocampal Remodeling and Epilepsy

open access: yesAnnals of Neurology, EarlyView.
Objective Autoimmune encephalitis (AE) is associated with autoantibodies targeting distinct neuronal populations. In AE, antibodies against glutamate decarboxylase 65 (GAD65), expressed in GABAergic interneurons, are frequently detected. In GAD65‐AE, hippocampal biopsies often show infiltrates of CD8+ cytotoxic T cells (CTLs), suggesting a prominent T ...

Serum Chitotriosidase Links to Activated Glia at Chronic Active Lesion Rims in Multiple Sclerosis Brain

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to explore the association between 18 kDa translocator protein (TSPO)‐positron emission tomography (PET)–measurable glial activation and serum chitotriosidase (CHIT1) in people with multiple sclerosis (pwMS), and its expression in postmortem MS brain tissue.

Patient‐Personalized Membrane‐Coated Magnetic Nanovectors: Probing the Biomimetic Interface for Targeted Tumor Theranostics

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study presents a label‐free spectroscopic platform to evaluate membrane protein conformation on patient‐derived glioblastoma cell membrane‐coated magnetic nanovectors. This work demonstrates that preserving membrane protein integrity during nanoparticle fabrication enhances homotypic tumor targeting and reduces hard protein corona formation ...

The species delimitation uncertainty principle.

open access: yesJournal of nematology, 2011
If, as Einstein said, "it is the theory which decides what we can observe," then "the species problem" could be solved by simply improving our theoretical definition of what a species is. However, because delimiting species entails predicting the historical fate of evolutionary lineages, species appear to behave according to the Heisenberg Uncertainty ...
