All-angle unidirectional flat-band acoustic metasurfaces.

Flat bands have empowered novel phenomena such as robust canalization with strong localization, high-collimation and low-loss propagation. However, the spatial symmetry protection in photonic or acoustic lattices naturally forces flat bands to manifest in pairs aligned at an inherently specific angle, resulting in a fixed bidirectional canalization. Here, we report an acoustic flat-band metasurface, allowing not only unidirectional canalization at all in-plane angles but also robust tunability in band alignment.

Exploring the General Acceptability and User Experience of a Digital Therapeutic for Cognitive Training in a Singaporean Older Adult Population: Qualitative Study.

Background: Singapore's large aging population poses significant challenges for the health care system in managing cognitive decline, underscoring the importance of identifying and implementing effective interventions. Cognitive training delivered remotely as a digital therapeutic (DTx) may serve as a scalable and accessible approach to overcoming these challenges. While previous studies indicate the potential of cognitive training as a promising solution for managing cognitive decline, understanding the attitudes and experiences of older adults toward using such DTx platforms remains relatively unexplored.

The prevalence of AACE has significantly increased, and various management approaches have been recommended in recent years. This study by the Council of Asia-Pacific Strabismus and Pediatric Ophthalmology Society aimed to provide an overview of the clinical features, etiology and the nonsurgical and surgical treatment recommendations for the condition to equip strabismus specialists with the most updated knowledge.

Mitochondrial Electron Flow Dynamics Imaging for Assessing Mitochondrial Quality and Drug Screening.

Mitochondrial quality control is paramount for cellular development, with mitochondrial electron flow (Mito-EF) playing a central role in maintaining mitochondrial homeostasis. However, unlike visible protein entities, which can be monitored through chemical biotechnology, regulating mitochondrial quality control by invisible entities such as Mito-EF has remained elusive. Here, a Mito-EF tracker (Mito-EFT) with a four-pronged probe design is presented to elucidate the dynamic mechanisms of Mito-EF's involvement in mitochondrial quality control.

Development and validation of the Health Segment Classification of Population Encompassed within Singapore (HealthSCOPES) framework.

Introduction: The population is heterogeneous with varying levels of healthcare needs. Clustering individuals into health segments with more homogeneous healthcare needs allows for better understanding and monitoring of health profiles in the population, which can support data-driven resource allocation.

Methods: Using the developed criteria, data from several of Singapore's national administrative datasets were used to classify individuals into the various health segments.

Higher Intron Retention Levels in Female Alzheimer's Brains May Be Linked to Disease Prevalence.

Multimodal study of Alzheimer's disease (AD) dorsolateral prefrontal cortex (DLPFC) showed AD-related aberrant intron retention (IR) and proteomic changes not observed at the RNA level. However, the role of sex and how IR may impact the proteome are unclear. Analysis of DLPFC transcriptome showed a clear sex-biased pattern where female AD had 1645 elevated IR events compared to 80 in male AD DLPFC.

Enhancing CO Oversaturation in the Confined Water Enables Superior Gas Selectivity of 2D Membranes.

Due to the global demands on carbon neutralization, CO separation membranes, particularly those based on two-dimensional (2D) materials, have attracted increasing attention. However, recent works have focused on the chemical decoration of membranes to realize the selective transport, leading to the compromised stability in the presence of moisture. Herein, we develop a series of 2D capillaries based on layered double hydroxide (LDH), graphene oxide, and vermiculite to enhance the oversaturation of CO in the confined water for promoting the membrane permselectivity.

Distinctive But Not Exceptional: The Risks of Psychedelic Ethical Exceptionalism.

When used clinically, psychedelics may appear unusual or even unique when compared to more familiar or long-standing medical interventions, prompting some to suggest that the ethical issues raised may likewise be exceptional. If that is correct, then perhaps psychedelics should be treated differently from other medical substances: for example, by being subjected to different ethical or evidentiary standards. Alternatively, it may be that psychedelics have more in common with various existing medical interventions than first meets the eye.

Ultimate water capillary evaporation in bamboo-inspired evaporator.

Bionic evaporators inspired by natural plants like bamboo and mushrooms have emerged as efficient generators through water capillary evaporation. However, primitive natural evaporators cannot currently meet growing demand, and their performance limitations remain largely unexplored, presenting a substantial challenge.

Half a Century's Quest for Seasonal Hyperacute Panuveitis (SHAPU): From Academic Curiosity to Public Health Concern.

For the past 50 years, significant progress has been made in understanding Seasonal Hyperacute Panuveitis (SHAPU), a mysterious blinding disease first reported in Nepal in 1975. Predominantly affecting Nepalese children, SHAPU occurs cyclically every odd year from September to December. While initially misclassified as endophthalmitis, SHAPU is set apart by its lack of trauma or surgery, failure to grow organisms in most intraocular fluid cultures, and its hallmark presentation of a "white pupil in red eye" with an association with moth exposure.

Calpain 2 regulates IL-1α secretion and inhibits tumor development via modulating calpain 1 expression in the tumor microenvironment.

Tumor-promoting inflammation significantly impacts cancer progression, and targeting inflammatory cytokines has emerged as a promising therapeutic approach in clinical trials. Interleukin (IL)-1α, a member of the IL-1 cytokine family, plays a crucial role in both inflammation and carcinogenesis. How IL-1α is secreted in the tumor microenvironment has been poorly understood, and we previously showed that calpain 1 cleaves pro-IL-1α for mature IL-1α secretion, which exacerbates hepatocellular carcinoma by recruiting myeloid-derived suppressor cells.

Investigating frontoparietal networks and activation in children with mathematics learning difficulties: Cases with different deficit profiles.

Approximately 15%-20% of school-aged children suffer from mathematics learning difficulties (MLD). Most children with developmental dyscalculia (DD) or MLD also have comorbid cognitive deficits. Recent literature suggests that research should focus on uncovering the neural underpinnings of MLD across more inclusive samples, rather than limiting studies to pure cases of DD or MLD with highly stringent inclusion criteria.

Study on the Hydrogen Evolution Reaction of Reinforced Concrete during Electrochemical Repair under the Influence of BIEM.

Based on the bidirectional electromigration (BIEM) technique, a corrosion inhibitor solution was prepared by mixing 1 mol/L triethylene tetramine with deionized water.

Subsequently, the hydrogen embrittlement risk of rebar was further characterized by mechanical property tests.

Cardiac-targeted delivery of a novel Drp1 inhibitor for acute cardioprotection.

Dynamin-related protein 1 (Drp1) is a mitochondrial fission protein and a viable target for cardioprotection against myocardial ischaemia-reperfusion injury. Here, we reported a novel Drp1 inhibitor (DRP1i1), delivered using a cardiac-targeted nanoparticle drug delivery system, as a more effective approach for achieving acute cardioprotection. DRP1i1 was encapsulated in cubosome nanoparticles with conjugated cardiac-homing peptides (NanoDRP1i1) and the encapsulation efficiency was 99.

Utility of multimodal imaging in the clinical diagnosis of inherited retinal degenerations.

Inherited retinal degeneration (IRD) is a heterogeneous group of genetic disorders of variable onset and severity, with vision loss being a common endpoint in most cases. More than 50 distinct IRD phenotypes and over 280 causative genes have been described. Establishing a clinical phenotype for patients with IRD is particularly challenging due to clinical variability even among patients with similar genotypes.
