A Novel Air‐Liquid Interface Exposure System for Continuous Gas Exposure of Airway Epithelial Cells: Exposure of NO2 With Viral Co‐Challenge

Journal of Applied Toxicology, EarlyView.
ABSTRACT Most in vitro toxicological research investigating the effects of inhaled compounds employ short‐term exposures of a couple of hours, or repeated, intermittent exposures for a limited number of days with exposure free periods, whereas in reality, we are continuously exposed, albeit to variable concentrations.

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

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

The 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 ...
