Polyphenol‐Based Biomaterials Against Cancer Radio/Chemotherapy‐Induced Intestinal Toxicity

Advanced NanoBiomed Research, EarlyView.
Radiotherapy/chemotherapy often causes intestinal toxicity, impairing cancer patients’ quality of life and treatment efficacy. Polyphenols protect against this injury via multiple mechanisms, but face oral use limitations. This review outlines their protective mechanisms and delivery challenges, highlighting recent oral delivery advances and future ...

Struktureller Mechanismus eines Aktivitäts‐Photoschalters am β2‐adrenergen Rezeptor

Angewandte Chemie, EarlyView.
Zeitaufgelöste Strukturen aus Messungen an Röntgen‐Freie‐Elektronen‐Lasern in Kombination mit zellulären Assays zeigen, wie der photoschaltbare β‐Blocker Photoazolol‐1 als Wirksamkeits‐Photoschalter der Funktion des β2‐adrenergen Rezeptor wirkt. Die lichtinduzierte Neupositionierung des Liganden verschiebt die Aktivität von inversem Agonistimus hin zu ...

Proteinvermittelte Kupfer‐Redoxregulation: Rolle von Disulfidbrücken und allosterischer Modulation

Angewandte Chemie, EarlyView.
Copper binding triggers structural changes that expose a reactive disulphide bridge, enabling intrinsic Cu(II) reduction in folded proteins. SAXS, XAS, and QM/MM simulations reveal how globular proteins such as HSA and SOD1 employ disulphide‐mediated dynamics to modulate site accessibility and control copper redox chemistry.

Structural Mechanism of an Efficacy Photoswitch Targeting the β2‐adrenergic Receptor

Angewandte Chemie International Edition, EarlyView.
Time‐resolved structures from x‐ray free‐electron laser measurements combined with cellular assays demonstrate how the photoswitchable β‐blocker photoazolol‐1 acts as an efficacy switch of β2‐adrenergic receptor function. Light‐induced ligand repositioning shifts activity from inverse agonism toward neutral antagonism by altering local helical ...

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, EarlyView.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

Animal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

RBD‐SD1 Nanoparticle Vaccines From DPP4‐Using Merbecoviruses Elicit a Cross‐Reactive Antibody Response but Limited Cross‐Protective Immunity

Biotechnology and Bioengineering, EarlyView.
SpyCatcher‐mi3 nanoparticles displaying RBD‐SD1 from MERS‐CoV, NL140422, and HKU4 elicited robust and cross‐reactive IgG responses in mice. Only MERS‐CoV RBD‐SD1 induced neutralizing antibodies against MERS‐CoV and protected human DPP4 mice from a MERS‐CoV challenge, indicating conserved serologic but limited cross‐neutralizing epitopes.

Intracellular self‐assembled nanoneedles for efficient lysosomal escape and CRISPR/Cas9 mediated gene editing

BMEMat, EarlyView.
PlaMnB was formed by cytolysin A‐tumor homing peptides (THP)‐modified bacterial membranes encapsulating the clustered regularly interspaced short palindromic repeat/CRISPR‐associated protein (CRISPR/Cas9) plasmid and manganese dioxide. THP‐containing bacterial membrane enhances PlaMnB vascular permeability and tumor targeting, and after cellular ...
