Unveiling how medical educators conceptualise resilience: a qualitative study.

BMC Med Educ

September 2025

Bau Institute of Medical and Health Sciences Education, Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong Special Administrative Region, China.

Background: Medical educators operate in high-pressure environments where resilience is critical to their well-being and professional effectiveness. Studies exploring how medical educators conceptualise resilience is limited, particularly outside Western contexts. As such, research investigating culturally-sensitive conceptualisations of resilience in an Asian context is overdue.

Introduction: Staff shortages following the pandemic and the growing complexity of healthcare require continuous reflection on the part of professionals to improve patient protection efforts in high-pressure environments. This makes it essential to better understand and reinforce the role of patient advocacy in clinical practice. This study aims to map the concept of patient advocacy in nursing, identifying its key attributes, antecedents, and consequences in acute and perioperative settings, contributing to its update and integration into the current healthcare paradigm.

Determining the composition, formation mechanisms and stability of the Hadean continental crust is essential for understanding the early geological history of Earth. Detrital zircons, largely from Jack Hills of Western Australia, provide the dominant direct records for the nature of continental crust during the Hadean eon and its formation processes. Although isotope and trace element compositions of these zircons are extensively determined, the major and trace element compositions of their host rocks and corresponding parental magmas remain largely debated, making the nature and evolution of the early Earth's crust ambiguous.

This study systematically investigates an Mn-Fe-Ni pseudo-ternary system for Na(Mn-Fe-Ni)O cathodes, focusing on the effects of varying transition metal fractions on structural and electrochemical properties. X-ray diffraction reveals that increasing Mn content induces biphasic behavior. A higher Ni content reduces the parameter, while higher Mn and Fe concentrations expand the lattice.

Filamenting temperature-sensitive mutant Z (FtsZ), a protein essential for bacterial cell division, is highly conserved across bacterial species but absent in humans, positioning it as a strategic target for the development of antibiotics. Significant efforts to identify FtsZ inhibitors- biochemical assays (, GTPase activity) and cellular approaches (, immunofluorescence)-have yielded over 100 natural products and synthetic compounds, whose cheminformatics clustering underscores a limited chemical diversity among the current scaffolds. Structural studies, including X-ray crystallography and cryo-electron microscopy, have resolved 97 FtsZ structures revealing conserved polymerization mechanisms and conformational plasticity, as exemplified by extremophile adaptations (, from the high-pressure environment of the Mariana Trench's Challenger Deep).

Material Physics and Technology at Extreme Conditions, Laboratory of Crystallography, University of Bayreuth, 95440 Bayreuth, Germany.

Polar metals have attracted growing interest due to both their significance in fundamental science and their potential functionalities. Here, we report the discovery of a novel polar metal, magnesium chloride MgCl, in which the metallicity of the polar structure is uniquely driven by attractive halogen interactions. MgCl was synthesized in laser-heated diamond anvil cells and observed at pressures of 28(2)-93(3) GPa.

Introduction: Curcumae Rhizoma (Ezhu) and Curcumae Radix (Yujin) are both derived from Curcuma kwangsiensis (CK), an important species in the Zingiberaceae family. They have different clinical applications in traditional Chinese medicine (TCM): The rhizome is mainly used for antitumor treatments, whereas the radix is known for antidepressant and cholagogic effects, both officially listed in the Chinese Pharmacopoeia. However, non-medicinal parts such as the aerial portions and fibrous roots are sometimes mixed in, leading to confusion in clinical formulation use.

Pressure serves as a fundamental tuning parameter capable of drastically modifying all properties of matter. The advent of diamond anvil cells (DACs) has enabled a compact and tabletop platform for generating extreme pressure conditions in laboratory settings. However, the limited spatial dimensions and ultrahigh pressures within these environments present significant challenges for conventional spectroscopy techniques.

In this study, we present a class of thin-film crosslinked (TFX) composite reverse osmosis (RO) membranes that resist physical compaction at ultrahigh pressures (up to 200 bar). Since RO membranes experience compaction at virtually all pressure ranges, the ability to resist compaction has widespread implications for RO membrane technology. The process described herein involves crosslinking a phase inverted porous polyimide (PI) support membrane followed by interfacial polymerization of a polyamide layer, thereby forming a fully thermoset composite membrane structure.

High-Pressure Synthesis of Metastable Superhydride PdH by Using Amorphous Pd as a Starting Material.

ACS Nano

September 2025

State Key Laboratory of High Pressure and Superhard Materials, College of Physics, Jilin University, Changchun 130012, China.

Pressure has been considered as a versatile and promising means in the discovery of metal superhydrides. However, although a series of metastable metal hydrides with excellent superconducting properties have been predicted through theoretical calculations, it is still challenging to obtain metal hydrides with metastable phases via a high-pressure synthetic route. Herein, we have successfully fabricated a metastable PdH superhydride using amorphous Pd nanoparticles (NPs) as a starting material at ∼32.

Current methods for evaluating the photostability of pharmaceutical drugs typically separate the irradiation step from the analytical process, making it challenging to observe real-time photodegradation during irradiation. The use of HPLC equipped with UV and/or MS detectors, which are commonly used for quantitative analysis, requires considerable time to establish optimal conditions, and employs organic solvents, which are harmful to both the environment and the analyst. The aim of this study is to investigate the effectiveness of isothermal differential scanning calorimetry (DSC) equipped with a UV probe (photo-DSC) for evaluating the photostability of pharmaceutical drugs in the solid state.

In light of the recent realization that a significant fraction of microbial biomass lives under high hydrostatic pressure, there is a renewed interest in understanding the molecular details by which proteins in these organisms modulate their functional native state. The effects of pressure on protein stability are defined by the volume changes between the native and denatured states. The conformational ensemble of the denatured state can depend on several extrinsic variables, such as pH and ionic strength of the solvent, temperature, and pressure.

Putting a lid on it: The N-terminal helix of Arf1 inhibits switching via uniform stabilization.

Biophys J

August 2025

The Arf and Arf-like GTPases, unlike all other Ras family GTPase members, exhibit a repressed conformation in their inactive, GDP-bound form. An important component of this autoinhibition is their N-terminal helix, which is missing in the other Ras family members. This helix caps a switch element called the interswitch, confining it to this repressed state.
