Lymph‐based liquid biopsy: Current progress and future potential

open access: yesInterdisciplinary Medicine, EarlyView.
Recent evidence under the revised Starling principle indicates that lymph‐based liquid biopsies may offer superior diagnostic performance over blood‐based counterparts in certain clinical scenarios, such as early‐stage solid tumor detection. Currently, various biomarkers within the lymphatic system show significant diagnostic potential for a range of ...

Mastoid Surgery Does Not Normalize Tympanometric Middle Ear Pressure in Children With Cholesteatoma

open access: yesThe Laryngoscope, EarlyView.
Conflicting mechanism‐based hypotheses have been used to promote selection of different approaches to management of the mastoid in order to optimize middle ear pressure homeostasis after removal of cholesteatoma. For example: (a) conservation of mastoid mucosa and opening of ventilation pathways endoscopically to normalize function, (b) removal of ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
