Treatment of complex perianal fistulas with fistula laser closure

Summary Aim Fistula laser closure (FiLaC) is a minimally invasive treatment option for perianal fistulas with acceptable healing rates. We report implementation and include short-term results in line with the IDEAL (Idea, Development, Exploration, Assessment, Long-term study) 2A...

Reactive Iron Mineral Phases on Mars: Implications for Organic Carbon Preservation

It is estimated that ∼20% of organic carbon stored in sediments on Earth is bound to reactive iron minerals. They often occur as nanoparticulate or X-ray amorphous iron (hydr)oxides, which are challenging to identify with mineralogical techniques—especially those that require any...

Bifacial InterfaceEngineering of Perovskite Memristorsfor High-Performance Optoelectronic Synapses and Neuromorphic VisionSystems

Abstract Conventional complementary metal-oxide-semiconductor (CMOS)-based intelligent visual systems suffer from inherent bottlenecks of high energy consumption and latency, while perovskite memristors are constrained by critical issues including defect-induced instability, unim...

Utilisation of Artificial Intelligence (AI) tools for research by Library and Information Science (LIS) lecturers in the University of Port Harcourt

This study investigated the utilisation of Artificial Intelligence (AI) tools for research by Library and Information Science (LIS) lecturers in the University of Port Harcourt. The study adopted a descriptive survey research design. The population comprised Library and Informati...

An Orbicularis Oculi-Related Band as a Potential Modifier of Tear-Trough Visibility: A Hypothesis-Generating Observation of a Layered Boundary in a Patient

Background/Objectives: A surface feature first noticed after aesthetic treatment may be misclassified as treatment-created. This single-patient observation examined a stable medial tear-trough contour noticed after midface volumization. The aims were to map its clinically continu...

Design of a New 3-UPU/S Parallel Ankle Rehabilitation Mechanism

Ankle injuries may lead to severe complications, including chronic instability and reduced mobility. Rehabilitation therefore plays a critical role in restoring normal ankle function and preventing long-term impairment. However, conventional manual physiotherapy presents several...

Baryon transition current structure (N(1440) Roper radial excitation F1 form factor) revisited: Insights from Patterson function analysis

This study employs Patterson function analysis to reconstruct the spatial distribution of the N(1440) Roper radial excitation Dirac‑type transition current based on empirical F1 form factors. By avoiding reliance on theoretical modeling, the method produces a sharply localized de...

From S2 to RP2: The non-orientable Schwarzschild spacetime

Einstein's field equations are local, so they retain their standard form on non-orientable manifolds, but the global structure of the solution need not be the same. We show that the orientability assumption in Hawking's horizon topology theorem is not redundant: dropping it produ...

Tackling anti-tumor macrophage function through genome engineering

In the realm of cellular immunotherapies, the synthetic chimeric antigen receptor (CAR) has proven to be a revolutionary modality, leading to the US Food and Drug Administration approval of multiple autologous CAR T cell products. Despite their remarkable success in hematological...

The Impact of Artificial Intelligence Development on Green Bond Issuance: Evidence From G20 Countries

The rapid advancements in artificial intelligence (AI) technologies are transforming the functioning of financial markets and significantly impacting the development of sustainable financing instruments. Green bonds, in particular, have become one of the fastest-growing capital m...

Multiple-adverse health conditions, mental health, and health-related quality of life in stroke survivors: Latent profile analysis and mediation analysis

Objective This study aimed to identify subgroups of stroke survivors based on multiple-adverse health conditions and determine the potential mediation effects of mental health in their relationship with health-related quality of life. Design A cross-sectional study. Setting Three...

Evicting the Usurpers and Reclaiming the Warp and Weft

This position paper critiques the contemporary fine art world’s commercial appropriation and systemic devaluation of traditional textile craft. Across major institutions and galleries, fabric is increasingly displayed not to honor the medium, but to monetize anonymous, highly ski...

Challenge Run Value (cRV): quantifying strategic value in MLB's ABS challenge era

We introduce Challenge Run Value (cRV), a pitch-level metric for valuing Automated Ball-Strike (ABS) challenges in Major League Baseball. Unlike framing metrics, which measure physical receiving skill under human umpiring, cRV treats the challenge as a scarce strategic resource w...

Haplotype phasing of de novo chromosome-level assembly of ‘Antonovka’ facilitated the identification of candidate genes for apple scab resistance

Malus genomic resources with improved quality are becoming an integral part of candidate gene identification and functional validation. Recently, we released a reference-based phased chromosome-level genome assembly of ‘Antonovka’ 172670B Malus domestica cultivar from the ‘Antono...

INTERNATIONAL ENVIRONMENTAL AGREEMENTS AND AFRICA'S COMMITMENT TO SUSTAINABILITY

Our Mother Earth is currently facing a lot of environmental concerns. The current environmental challenges represent a considerable measure of danger to the well-being of people and creatures. The environmental problems like global warming, acid rain, air pollution, urban sprawl,...

The Layered Semantic Encoding System: Position-Typed Semantic Records with Dual Textual and Matrix Serialization

The Layered Semantic Encoding System (LSES) is a self-contained architecture for converting bounded source meanings into compact, reversible semantic records and rendering them through either a technical textual profile or a geometric visual profile. Its central mechanism is posi...

Are sustainable plant-based diets suitable for all? A nutrigenetic perspective

Background While global nutrition policies increasingly promote plant-based diets for environmental sustainability, this approach may implicitly assume biological homogeneity and overlook interindividual genetic variability in nutrient metabolism. Aim This review evaluates potent...

Doula Support During Pregnancy, Childbirth, and Postpartum

OBJECTIVE: To systematically review the evidence on doula support in pregnancy, birth, and postpartum. DATA SOURCES: PubMed, Cochrane Library (which includes clinical trials), CINAHL, PsycInfo. METHODS OF STUDY SELECTION: Eligible studies were English-language randomized controll...

Physicists find strong evidence for elusive ‘glueball’

Long-sought particle, made of force-carrying gluons, represents a new type of matter

Macroevolutionary dynamics of Androsace s.l . (Primulaceae) across the Northern Hemisphere

Abstract Mountain regions of the Northern Hemisphere harbor exceptional biodiversity, yet the processes underlying species diversification and migration among these regions remain poorly understood. This study investigates the macroevolutionary dynamics of Androsace s.l ., a genu...
