High‐Pressure Synthesis of Quantum‐Stabilised Manganese Superhydride MnH7

Angewandte Chemie, EarlyView.
Superhydrides are a rarity in transition metal hosts. Through high‐pressure, high‐temperature diamond anvil cell studies, the most hydrogen‐rich transition metal hydride, MnH7${\rm MnH}_7$ has been synthesised. Density functional theory calculations demonstrate that zero‐point energy stabilises the crystalline structure that MnH7${\rm MnH}_7$ adopts ...

Timing of gene expression in a cell‐fate decision system

Molecular Systems Biology, 2018
During development, morphogens provide extracellular cues allowing cells to select a specific fate by inducing complex transcriptional programs. The mating pathway in budding yeast offers simplified settings to understand this process. Pheromone secreted

Perceived Time Shapes Physical Fatigue Accumulation and Its Neural Oscillatory Correlates

Advanced Science, EarlyView.
Can a clock change the course of physical fatigue? By covertly manipulating the clock calibration during repeated isometric contractions, we showed that perceived time shapes fatigue accumulation and frontal oscillatory dynamics. While fatigue accumulation was only reduced when the clock was slowed down, frontal oscillatory dynamics followed perceived ...

Apolipoprotein F is reduced in humans with steatosis and controls plasma triglyceride‐rich lipoprotein metabolism

Hepatology, EarlyView., 2022
Hepatic APOF transcript levels correlate inversely with plasma TG and hepatic steatosis in humans. ApoF expression in mice promotes VLDL‐TG production and lipoprotein remnant clearance in mice. Abstract Background NAFLD affects nearly 25% of the global population. Cardiovascular disease (CVD) is the most common cause of death among patients with NAFLD,

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces

Angewandte Chemie, EarlyView.
Hydroxyl‐functionalized dicarbaporphyrinoid polymers synthesized on Au(111) enable tunable oxygen‐mediated connectivity under UHV conditions. Thermal activation yields one‐dimensional hydroxyl‐terminated polymers that can selectively evolve into either covalently‐linked dibenzo‐p‐dioxane architectures through intermolecular C–O–C coupling or two‐fold ...

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion

Advanced Science, EarlyView.
In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Taxonomic study of the isopod crustaceans from the Spanish expedition Antártida 1986-11 in the Scotia Sea, South Atlantic

Scientia Marina, 1999
This paper summarizes the results of a taxonomic study of the isopods collected during the Antártida 1986-11 expedition. A total of 123 specimens were studied, of which 99 were in the adult or juvenile phases and 24 were in the postmanca phase.
