Comparison of response to LPS-induced sepsis in three DBA/2 stocks derived from different sources

open access: yesLaboratory Animal Research, 2021
Sepsis, one of the most fatal diseases in the world, is known to culminate in multiple organ failure due to an uncontrolled inflammatory response. Hence, the use of animal models in sepsis research is very important to study complex immune responses. The

NAD+ Metabolism Licenses Zygotic Genome Activation via PARP7‐Mediated ADP‐Ribosylation of UHRF1 in Mouse Early Embryos

open access: yesAdvanced Science, EarlyView.
This study uncovers a metabolic‐epigenetic axis licensing zygotic genome activation (ZGA) in mouse embryos. A developmental decline in NAD+ levels activates PARP7, which mono‐ADP‐ribosylates and stabilizes UHRF1. This modification promotes the establishment of permissive histone acetylation marks, thereby facilitating timely ZGA.

Palladium‐Catalyzed Annulations of an Anti‐Bredt Olefin

open access: yesAngewandte Chemie, EarlyView.
We report metal‐catalyzed trappings of a [2.2.1]‐bridged bicyclic anti‐Bredt olefin (ABO). The methodology yields unusual heterocyclic products and is expected to prompt the further development of unconventional reactions, including metal‐catalyzed processes of ABOs and other strained olefins. ABSTRACT A famous class of alkene‐containing compounds that

Cerium Nanoparticle‐Mediated Inhibition of the NSUN2/m5C Axis Suppresses Synovial Aggression in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
A novel epitranscriptomic mechanism in rheumatoid arthritis is uncovered: NSUN2 promotes disease via m5C‐dependent stabilization of ICMT mRNA, fueling the migration and invasion of pathogenic RA FLS. Targeting this axis with engineered nanoparticles (Ce/SAA NPs) effectively inhibits disease progression, presenting a precise therapeutic strategy ...

Adaptive Hydrogenation of Alkynes Using CO as a Molecular Trigger to Selectively Produce Alkanes or Z‐Alkenes

open access: yesAngewandte Chemie, EarlyView.
One catalyst for two products: CO acts as a molecular trigger for adaptive alkyne hydrogenation using supported Pd nanoparticles. The catalyst reversibly switches between the formation of alkanes under H2 and Z‐alkenes under H2/CO for 37 structurally diverse alkynes.

Barrier‐forming, drug‐free nasal spray reduces allergic symptoms induced by house dust mite allergen

open access: yesClinical and Translational Allergy, 2023
Background House Dust Mite (HDM) is the most common indoor allergen triggering allergic symptoms. First‐line pharmacotherapy treatment is recommended in international guidelines, while the avoidance of allergens represents a still unmet guideline ...

Pd‐Catalyzed Asymmetric Dearomative Heck/Tsuji‐Trost Difunctionalization of Naphthalenes

open access: yesAdvanced Science, EarlyView.
We have developed a palladium‐catalyzed asymmetric dearomative Heck/Tsuji‐Trost 1,4‐difunctionalization reaction of naphthalenes, affording 4‐aminospirocyclohexene oxindole products bearing two remote chiral centers. Through the effect of the newly designed chiral sulfinamide phosphine ligand with large steric hindrance, side reactions are inhibited ...

Targeted Degradation of Picornaviral 3C Protease via PROTACs Confers High Barrier to Viral Resistance and Broad‐Spectrum Antiviral Activity

open access: yesAdvanced Science, EarlyView.
This study reports D34 as the first PROTAC degrader that targets the 3C protease of picornaviruses. D34 effectively degrades EV71 3C protease via the ubiquitin‐proteasome pathway. More importantly, D34 exhibits a high resistance barrier and shows broad‐spectrum antiviral activity against multiple picornaviruses, highlighting its potential as a novel ...

Contact Dermatitis Caused by Dermabond Advanced Use

open access: yesPlastic and Reconstructive Surgery, Global Open, 2018
Background:. Dermabond Advanced (DBA) has been widely used globally; however, severe contact dermatitis (CD) can be a serious adverse effect of DBA use. In this study, we investigated the characterization and incidence rate of CD after using DBA and the ...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

open access: yesAdvanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...
