AlN-based aerogel thermo-cooler enabled by enhanced phonon conduction and unconstrained liquid capillarity

open access: yesNature Communications
Transpiration cooling is a thermal management technique that utilizes the phase change of liquid coolant to effectively dissipate heat. Porous ceramic media play a crucial role in this cooling process by facilitating liquid transport and heat exchange ...

A tumor microenvironment-responsive poly(amidoamine) dendrimer nanoplatform for hypoxia-responsive chemo/chemodynamic therapy

open access: yesJournal of Nanobiotechnology, 2022
Background Chemodynamic therapy is a promising cancer treatment with specific therapeutic effect at tumor sites, as toxic hydroxyl radical (·OH) could only be generated by Fenton or Fenton-like reaction in the tumor microenvironment (TME) with low pH and

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Intermolecular selective carboacylation of alkenes via nickel-catalyzed reductive radical relay

open access: yesNature Communications, 2018
To date the carboacylation of alkenes has been reported only in single- and two-component methodologies. Here, the authors report a three-component nickel-catalyzed carboacylation of olefins which enables the rapid construction of ketones with high ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Constructing Activatable Photosensitizers Using Covalently Modified Mesoporous Silica

open access: yesAdvanced Science
The combination of photosensitizers (PSs) and nanomaterials is a widely used strategy to enhance PS efficacy and broaden their applicability. However, the current nanocarrier‐based delivery strategies focus on conventional PSs, neglecting the critical ...

Preparation and Application of Modified Vermiculite Adsorption Materials

open access: yesKuangchan zonghe liyong
β-Cd polymer (KACD) was prepared by modifying β-Cd with KH560 at alkaline conditions, and then the polymer was loaded onto vermiculite to prepare β-Cd modified vermiculite composite (KACDS).
