Effect of Prophylactic Incisional Negative Pressure Wound Therapy on Surgical Site Infection After Emergency Laparotomy: An Updated Meta‐Analysis With Trial Sequential Analysis

ABSTRACT Introduction Patients undergoing emergency laparotomy are at high risk of surgical site infections (SSI), which contribute substantially to postoperative morbidity. Incisional negative pressure wound therapy (iNPWT) has been shown to reduce the incidence of SSI following...

Longitudinal gut microbiome dynamics in neurosurgical ICU patients: Enterococcus expansion as a feature of microbial restructuring

Abstract Background Gut microbiota alterations are commonly observed in critical illness, but their temporal dynamics in neurosurgical ICU patients remain insufficiently characterized. This study aimed to describe postoperative microbial trajectories and their clinical context du...

Structural Principle of Entanglement Core Framework

The 6.0 release of the PSE — Structural Principle of Entanglement represents the fully stabilized and final formulation of the theory, following the complete consolidation of its fundamental ontological chain: 𝑺 ⟶ 𝑫𝑺(𝒇) ⟶ 𝑪𝒇 ⟶ 𝑫s(𝒆) ⟶ 𝑪𝒆 ⟶𝒟physical. The transitions between the le...

Environmental Perturbation and the Progressive Establishment of Intestinal Stem-Cell Dysfunction: A Hypothesis Linking Niche Resilience to Ageing

This hypothesis article explores how environmental perturbations may contribute to age-associated intestinal stem cell dysfunction. It proposes that early alterations may initially be compensated by niche resilience, while repeated or prolonged stress may progressively reduce reg...

A Comparative Financial Performance of Bharti Airtel and Jio Financial Services Ltd

The telecommunications sector in India has experienced a profound shift in recent years, propelled by fierce rivalry, technological innovations, and changing consumer preferences. Reliance Jio and Bharti Airtel have established themselves as the preeminent entities, influencing t...

Immunoinformatics-based design and in silico evaluation of a PstS-derived multi-epitope vaccine candidate against Salmonella typhimurium

Abstract Salmonella typhimurium is a major foodborne pathogen with increasing multidrug resistance and limited vaccine options. This study aimed to design a multi-epitope vaccine targeting the PstS protein using an immunoinformatics approach. B-cell and T-cell epitopes were predi...

Early electrophysiological differentiation of faces and face-like stimuli in pediatric traumatic brain injury

Pediatric traumatic brain injury (PTBI) may disrupt neurodevelopmental systems supporting social perception, including the rapid processing of facial information. Although face perception is essential for social interaction, little is known about how children with TBI process amb...

Performance Evaluation of K-Type Thermocouple-Based Temperature Measurement Using ESP32

This paper describes the experimental testing of a temperature measurement system that uses a K-type thermocouple and an ESP32 microcontroller. The experimental setup was designed to measure temperatures ranging from 25°C to 600°C, with a laboratory furnace serving as the heat so...

Lamellar high-entropy TiVCrMoC3 MXene enabling excellent hydrogen storage kinetics and cyclic stability of MgH2 via multi-phase interfaces and multiple transition metals effects

MgH2 is a promising hydrogen storage medium, but its industrial use is hindered by high dehydrogenation temperatures and sluggish kinetics. Herein, a lamellar high-entropy TiVCrMoC3 MXene was synthesized via HF-mediated etching of a TiVCrMoAlC3 MAX precursor and integrated into M...

A Staged Revascularization Strategy for Chronic Limb‐Threatening Ischemia With GLASS Stage IMP2 Disease: Distal Bypass Following Infrapopliteal/Pedal Endovascular Therapy

Patients with chronic limb-threatening ischemia (CLTI) and Global Limb Anatomic Staging System (GLASS) stage IMP2 disease often lack suitable inframalleolar target arteries for distal bypass on conventional imaging, rendering them technically ungraftable. We adopted a staged reva...

FINDING: Phyllotaxis spiral count converges to irrational rotation number \(1/\phi^2\) via a recursive PDE model, linking Fibonacci numbers to plant morphogenesis. MATH: - Irrational rotation number: \(1/\phi^2 = (3 - \sqrt{5})/2 \approx 0.381966\) - Fibonacci sequence: \(F_{n+2}...

A Machine-Checked Modulo 24 Reduction of the Erdős-Straus Conjecture in Lean 4

While the global conjecture remains open for a thin set ofprime residues, significant structural progress has been achieved through modular congruencesieves. In this paper, we establish and mechanically verify in the Lean 4 interactive theoremprover (via Mathlib) the Master Modul...

Non-Hermitian Resolvent Geometry: Pseudospectral Curvature and the Gauss-Bonnet-Schur Theorem

The classical spectral theorem fails for non-normal operators (A A† ≠ A† A), rendering isolated eigenvalues blind to pseudospectral instabilities, eigenvector non-orthogonality, and extreme perturbation sensitivities in open quantum systems and advective dynamics. We establish a...
