Imaging plays a critical role in the management of chronic liver disease (CLD) because it is a safe and painless method to assess liver health. The widely used imaging techniques include ultrasound, computed tomography and magnetic resonance imaging. These techniques allow the measurement of fat deposition, iron content, and fibrosis, replacing invasive liver biopsies in many cases.

While the use of phages in the food and biomedical sectors occurs commercially, their application in the water sector is less common and is typically demonstrated at a lower technological readiness level. This is so despite the potential that phages have to enhance the control of problematic bacteria (including pathogens) and protect infrastructure within the water sector. Fulfilling the great potential of this nascent field requires more research and development.

Rationale And Objectives: To investigate the effect of ComBat harmonization on the stability of myocardial radiomic features derived from multi-energy CT reconstructions.

Materials And Methods: A retrospective study was conducted on 205 patients who underwent dual-energy chest CTA at a single center. The data was reconstructed into multiple spectral reconstructions (mixed energy simulating standard 120 Kv acquisition and monoenergetic images ranging from 40 to 190 keV in increments of 10).

Uncontrolled anthropogenic activities have contaminated water resources with emerging contaminants such as pharmaceuticals, pesticides, microplastics, per- and poly-fluoroalkyl substances (PFAS), and heavy metals, making them unsuitable for living ecosystems. Emerging contaminants pose a severe threat to ecosystems. Hence water treatment methods through improved efficiencies are essential for removing these contaminants at ease of application and at low energy.

Article Synopsis
  • - The study aimed to evaluate smartphone usage patterns and their effects on the eye's accommodation and convergence systems among Malaysian teenagers aged 13 to 17, involving 62 participants using questionnaires and eye exams.
  • - Findings indicated that teenagers use smartphones for over 6 hours daily, mainly for videos and games, yet most did not report any eye strain or prescription changes; however, after 30 minutes of continuous use, eye accommodation and convergence abilities significantly decreased.
  • - The research concluded that frequent smartphone use increases visual stress, weakening eye functions, and recommended taking regular breaks and following the 20-20-20 rule to help maintain eye health.
