Isolation and Identification of Staphylococcus Species From Mastitic Dairy Cows and Associated Risk Factors in and Around Bahir Dar, Ethiopia

ABSTRACT Background Bovine mastitis remains one of the most frequent and costly diseases affecting dairy cattle, with significant impacts on health, welfare, and productivity. Staphylococcus species are among the major pathogens responsible for bovine mastitis, leading to reduced...

Revisiting Conventional IDF Curves Using Energy-Based 30-Minute Peak Rainfall Intensity for Urban Stormwater Design: Evidence from İstanbul

Urban drainage systems in rapidly growing cities such as Istanbul are increasingly stressed by short-duration, high-intensity storms that exceed the assumptions of conventional Intensity–Duration–Frequency (IDF) design curves. This study re-examines 1-minute rainfall records from...

Beyond HPV16/18: genotype distribution of high-risk HPV and cycle threshold values in cervical carcinogenesis spectrum

Background Cervical cancer is a virus-dependent gynaecologic malignancy and according to GLOBOCAN 2022 cervical cancer is the fourth frequent women cancer in all over the world. Despite this frequency it is rarely seen in developed countries because of the enforcement of cervical...

Unilateral Functionalization of Covalent Organic Frameworks: Local Electronic Modulation and Morphology-Enabled Mass Transport for Electrocatalytic Hydrogen Peroxide Production

Abstract Achieving high selectivity and activity in the two-electron oxygen reduction reaction (2e– ORR) pathway critically depends on the synergistic modulation of a catalyst’s electronic structure and mass diffusion channels. This work proposes an asymmetric modulation strategy...

A pre–post study of self-esteem, self-concept and body image among adolescents in the context of a co-created community intervention on screen use

Introduction Excessive screen use negatively affects adolescents’ self-esteem, self-concept, and body image, largely due to social comparison on digital platforms. Educational interventions are often less effective without community involvement, highlighting the importance of an...

Deadly dates: The relationship between holy days and terrorism

How do terror groups make strategic decisions regarding when to time their attacks? This study examines the logic underpinning attack timing and argues that non-state groups weigh the benefits of amplified psychological impacts during focal points for violence against the costs o...

Lifestyle-Associated Biomarkers of Cellular and Whole-Organism Aging: A Practical Roadmap for Human Geroscience Trials

Aging is a multidimensional biological process that is not adequately captured by chronological age alone. Geroscience—the study of biological mechanisms that drive age-related functional decline and disease susceptibility—therefore requires biomarker frameworks that can identify...

Moral Courage vs. Moral Deference: Ethical Leadership and Employee Outcomes During AI-Assisted Internal Crises

This study examines how leadership stance and AI disclosure shape employee responses to CEO communication during an internal, value-based crisis. It further examines the mediating roles of perceived message sincerity and negative moral emotions and the moderating role of employee...

Task Motivation, Task Emotions, and Cognitive Engagement in L2 Oral Tasks: The Case of Chinese Post-Secondary L2 Learners of English

Drawing on control-value theory and situated expectancy-value theory, this study investigated the relationships between task motivation (i.e., expectancy for success, task values, and task cost), task emotions (i.e., task enjoyment and task anxiety), and cognitive engagement in L...

Molecular Interactions of Bioactive Peptides with Proteins and DNA

Background: This study investigates the molecular recognition of two biologically active peptides (P1 and P2) by key biomacromolecular targets. The studied peptides were previously identified in Babylon snail hydrolysates and have been shown to exhibit antioxidant and cytotoxic a...

The Aggregate Index of Systemic Inflammation and Risk of Perforation, Mortality, and Surgery in Ileus

Abstract This article aims to evaluate the relationship between the aggregate index of systemic inflammation (AISI) and the occurrence of perforation, the likelihood of surgical management, and in-hospital mortality in patients with ileus, and to assess its diagnostic performance...

Two-Dimensional Simulations of Long-Term Morphological Evolution Around Tidal Inlets

Tidal inlets connect bays or lagoons to the ocean and undergo continuous morphological changes under the action of tides and waves. Numerical simulations of long-term morphological evolution near tidal inlets are computationally expensive because small time steps are needed for n...

Advances in Substrate Recognition, Catalytic Mechanisms, and Engineering Applications of Alginate Lyases

Alginate lyases depolymerize alginate via β-elimination and serve dual roles in brown-algal biorefining and antibiofilm therapy. Brown-algal and bacterial alginates differ substantially in O-acetylation, yet this key structural distinction and its implications for enzyme performa...

Surgical treatment options for chronic complete traumatic ruptures of digital flexor tendons in dogs

The article describes the treatment results for four dogs with confirmed chronic complete ruptures of the deep and superficial digital flexor tendons.Surgical treatment involved exploration of the injury site, mobilization of the torn tendon ends, and end-to-end repair using a tw...

Phase-change-coupled thermochromic radiative cooling smart windows

Smart windows capable of adaptive solar regulation, thermal energy storage, and radiative heat management are promising for improving building thermal regulation efficiency under variable climatic conditions. Herein, a phase-change-coupled thermochromic radiative cooling (PTRC) s...

Permission meets pressure: institutional risk, CEO self-monitoring and extreme strategic change

Purpose Explain why some multinationals pursue extreme strategic shifts whereas others opt for incremental change by testing how national institutions and CEO behavior interact. Design/methodology/approach We merge institutional-discretion theory with upper-echelons logic in a mo...

Adaptive AI Governance Framework in the Territorial Context of a University Business Incubator: PRE–POST Perception Evidence, Stakeholder Heterogeneity, and Provisional Routing Rules

Artificial intelligence (AI) is spreading across educational, productive, and institutional settings, creating a need for governance approaches that can adapt to heterogeneous stakeholders. This study proposes an adaptive AI governance framework for the territorial context of a u...

Twisted Rings and Twisted Signals: The Sector Calculus of Rotational Twists

A twist can live in a signal or in a ring. A twisted signal returns after one period multiplied by a fixed phase. A twisted ring is a solid ring whose transported frame returns turned by an angle. This article shows that the two are one structure. On the flat model of the ring, t...

Reprogramming tumor cells with LCOR mRNA nanotherapy to enhance immunotherapy

Transcription factors (TFs) are often considered undruggable due to their structural complexity. mRNA technologies can overcome this therapeutic limitation by enabling dynamic protein replacement therapies. Here, we explore the TF activity of LCOR (Ligand‐dependent corepressor),...

Effect of a Mentored Virtual Research Fellowship on Research Competencies and Activities of Nurses

Background: Nurses should lead research activities to improve patient care, especially in Magnet ® -designated hospitals. One organization used a 6-month virtual mentored registered nurse research fellowship to overcome participation barriers. Method: Nurses across 24 hospitals i...
