Water distribution and phase angle based on bioelectrical impedance analysis: a convenient approach for identifying acute decompensated heart failure with preserved ejection fraction in older adults

Acute decompensated heart failure with preserved ejection fraction (ADHFpEF) is highly prevalent in older adults, but early recognition is difficult. Bioelectrical impedance analysis (BIA) provides a non-invasive and convenient assessment of fluid status, but its discriminative v...

Vascular tree structure-based perfusion phantom fabrication using modified Hele-Shaw cell method

Tissue phantoms mimicking microvasculature and perfusion are essential for vasculature modelling and calibrating imaging systems, which require faithful replication of vascular geometry and flow. Conventional fabrication methods, including lithographic micromachining and additive...

Innovative Millenium Action Plan For The Reintroduction Of Extinct Cheetah In India: Success Or Failure Will Depend On Application Of AI Technology?

Abstract:The Asian cheetah, Acinonyx jubatus (venaticus) is a mesopredator or mesocarnivore thatevolved more than 5.5 million years ago in the Miocene period isone among other cats classifiedin the family Felidae, is one of the fastest marvelous cursorial cat its average speed be...

Comparison of PMAneo and RAPID in acute ischemic stroke: agreement in CT perfusion analysis and DEFUSE 3 imaging eligibility

Abstract Purpose Automated computed tomography perfusion (CTP) analysis plays a key role in triaging acute ischemic stroke (AIS). This study aimed to evaluate the agreement of PMAneo compared with RAPID in a multicenter setting. Materials and methods We retrospectively reviewed 9...

Oxidative conversion of HEDP to phosphate in charged water microdroplets

Organophosphonates are persistent anthropogenic phosphorus compounds because of their stable carbon–phosphorus bonds. Whether such compounds can be oxidatively converted to inorganic phosphate at dynamic air–water interfaces remains poorly understood. Here, using 1-hydroxyethylid...

Interplay between Densification and Thermochemical Conversion in Sewage Sludge Pyrolysis

Abstract This research investigates sewage sludge pyrolysis as a route for biochar production, comparing in natura and pelletized feedstocks under slow pyrolysis conditions. Experiments were conducted in a batch reactor at 400–500 °C, with a heating rate of 5 °C min–1 and a resid...

Social work for youth development in Botswana: a case for a developmental approach

This study examines the role of social work in youth development and socio-economic empowerment in Botswana. A qualitative research approach was adopted, with data collected through face to face semi-structured interviews with 20 professionally qualified social workers employed a...

Clinical and imaging characterization of ocular toxoplasmosis in a Central-West Brazilian population

Abstract Objective To evaluate and characterize patients with presumed ocular toxoplasmosis using combined clinical and serological approaches in the municipality of Três Lagoas, Mato Grosso do Sul, Brazil. Methods This cross-sectional quantitative study included 85 patients with...

Is (AI-guided) coronary CT angiography ready for prime time in diabetes care and research?

Abstract Due to its increasing prevalence, the burden of diabetes-attributable cardiovascular disease is projected to increase substantially. At the same time, there is a growing need to better identify patients at the highest cardiovascular risk and to optimize the use of increa...

Navigating the multifunctional transition of peri-urban agriculture: The role of adaptive governance in Guangzhou, China

Peri-urban agricultural systems (PUAS) face competing demands for production, ecological conservation, and urban-oriented services, yet the interactions shaping their multifunctional transition remain insufficiently understood. Integrating a social–ecological systems perspective,...

Comparative Techno-Economic Analysis of Novel Closed-Loop Hydronic Cooling of PV Panels in Hot and Arid Regions

The elevated operating temperature of photovoltaic (PV) modules in hot and arid regions accelerates performance degradation, reduces electricity generation, and adversely affects long-term economic viability. This study presents a comprehensive long-term comparative thermo-econom...

Chemically Powered High-Aspect-Ratio Cilia with Tunable Biomimetic Motion

Abstract Cilia are ubiquitous biological actuators that drive essential functions ranging from clearing contaminants from mammalian lungs to enabling locomotion and feeding in microorganisms. Their utility has inspired the development of artificial cilia. Yet while natural cilia...

A Dication-Mediated Rapid 4-Amination of Methoxy Pyridine

Abstract 4-Aminopyridines are key structures in pharmaceuticals. SNAr reactions typically require electron-deficient starting materials, and it remains difficult to overcome this limitation without the use of transition metals. Herein, we report the urea-based organic dication as...

Mapping the brkA Promoter Region on pDO6935 in Escherichia coli Using pLISA, A Novel Promoterless GFP Reporter Plasmid

Bordetella resistance to killing A (brkA) is a serum resistance gene encoding an autotransporter native to Bordetella pertussis, the causative agent of whooping cough (1). Using the expression construct pDO6935, previous studies have demonstrated brkA expression in Escherichia co...

SMS3C1: A Post-Quantum Tamper-Evident Record That Survives the Fall of Its Own Mathematics

SMS3C1 is a tamper-evident record whose every seal is signed under eight mathematically unrelated families of digital signature at once and, beneath them, carries an information-theoretic authentication tag per custodian site from one-time key material the recording device erases...

Deleting the hns Gene for the H-NS Protein in Escherichia coli Reduces the Transformation Efficiency Following the Heath Shock Transformation Protocol

One commonly used, yet little understood method for transferring DNA into cells is the temperature shock transformation method (TST) that exposes competent bacteria to o o successive temperatures (4 C and 42 C). This study tested the effect of the gene for the heatstable nucleoid...

Where AI enters the product development process: Task orientation, human identity threat, and purchase intention

Artificial intelligence (AI) is increasingly moving beyond analytical retail functions into product development, raising new questions about how consumers respond depending on where AI is positioned within the process. Across three studies with U.S. consumers in fashion-related c...

NEUROMETABOLIC PHENOTYPE OF TORCH-ASSOCIATED AUTISM IN CHILDREN
