Treatment Response Evaluation in Necrotizing Otitis Externa Using 18F-FDG-PET Imaging.

Objective: This study aims to identify 18F-FDG-PET imaging features for improving treatment response evaluation in patients with necrotizing otitis externa (NOE), aiding in the difficult differentiation between sterile inflammation and active infection.

Study Design: Retrospective cohort study.

Setting: Tertiary hospital.

Chalk stream restoration: Physical and ecological responses to gravel augmentation.

To mitigate the morphological and ecological impacts of direct (e.g. dredging) and indirect (e.

Fish habitat models for a future of novel riverscapes.

Multiple anthropogenic forces have pushed river ecosystems into undesirable states with no clear understanding of how they should be best managed. The advancement of riverine fish habitat models intended to provide management insights has slowed. Investigations into theoretical and empirical gaps to define habitat more comprehensively across different scales and ecological organizations are crucial in managing the freshwater biodiversity crisis.

Aging enhances pro-atrogenic gene expression and skeletal muscle loss following respiratory syncytial virus infection.

Aging and many age-related health conditions are associated with skeletal muscle loss. Furthermore, older adults are more susceptible to severe respiratory infections, which can in turn lead to muscle wasting. The mechanisms by which respiratory viral infection can impact skeletal muscle in older adults are not well understood.

Laying the foundations for selective-fish guidance using electricity: multi-species response to pulsed direct currents.

To develop effective technology that employs electric fields to simultaneously guide valued freshwater fish whilst limiting the range expansion of undesirable invasive species, there is a need to quantify the electrosensitivity of multiple families. This experimental study quantified the electrosensitivity of two carp species that, in UK, are invasive (grass carp, , and common carp, ) and compared the values with those previously obtained for adult European eel (), a species of conservation concern in Europe. Electric field strengths (V/cm) required to elicit physiological responses (, and ) were identified across four pulsed direct current (PDC) electric waveforms (single pulse-2 Hz, double pulse-2 Hz, single pulse-3 Hz and double pulse-3 Hz).
