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.

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.

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.

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.

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.

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. Through extensive experimentation and detailed simulation analysis, this study presents a precisely engineered H-type bamboo steam generator.

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.

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.

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.

Based on the bidirectional electromigration (BIEM) technique, a corrosion inhibitor solution was prepared by mixing 1 mol/L triethylene tetramine with deionized water. The effects of current density, charging time, and corrosion inhibitor on critical current density and hydrogen content of rebar were investigated. Subsequently, the hydrogen embrittlement risk of rebar was further characterized by mechanical property tests.

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.

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.

This report describes a patient with polypoidal choroidal vasculopathy (PCV) with fovea-involving retinal pigment epithelium (RPE) tear that showed tissue remodeling with a good visual outcome. Imaging over the patient's clinical course from 2019 was reviewed. A 74-year-old female presented with left submacular hemorrhage and a large multi-lobular pigment epithelial detachment.

Intraoperative optical coherence tomography (iOCT) has been applied and studied in a variety of vitreoretinal surgeries for its feasibility, safety, and outcomes for years. Common scenarios include membrane peeling procedures, retinal detachments, choroidal-retinal biopsies, Argus implants, and subretinal injections. iOCT offers the surgeon a better understanding of the retinal microarchitectural changes and timely intraoperative feedback, directing a future view of precision surgery.

Transcatheter aortic valve implantation (TAVI) has been established as an effective treatment modality in patients with severe aortic stenosis (AS) and the uptake of TAVI is rapidly growing in the Asia-Pacific region. However, there exist a heterogeneity in the management of aortic stenosis and the use of TAVI among countries in the region. Reasons for these differences include anatomic variations, disparity in healthcare resources and infrastructure, and the lack of consensus on the optimal management of AS in the Asia-Pacific region.
