Extent of Sinus Surgery Is Associated With Disease Control in Biologic Treated Type 2 Dominant CRS

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background A greater benefit of biologics is observed after surgery in Type 2 chronic rhinosinusitis with nasal polyps (CRSwNP). However, the extent of surgery remains undefined in many studies. This study evaluated the extent of surgery on disease control in patients receiving biologics for refractory Type 2 dominant CRSwNP.

Modeling the Ames test

Mutation Research/Environmental Mutagenesis and Related Subjects, 1981
Despite the value and widespread use of the Ames test, little attention has been focused on standardizing quantitative methods of analyzing these data. In this paper, a realistic and statistically tractable model is developed for the evaluation of Ames-type data.

Regression analysis of ames test data

Environmental Mutagenesis, 1981
AbstractWeighted least squares estimation is used for fitting nonlinear models to Ames test data. The models are biologically plausible, incorporating mutagenicity, toxicity, and/or saturation. Regressions are weighted to compensate for variance that changes with mean and to attain outlier resistance.

Funktionale Tests am Demonstrator

2020
Zur Validierung der integrierten Funktionen wurden funktionale Tests an Komponenten des LeiFu-Unterbodens durchgefuhrt. Hierbei wurden exemplarisch das Crashverhalten, das NVH-Verhalten, die thermische Isolation bzw. Abstrahlung sowie integrierte elektrische als auch sensorische Funktionen experimentell validiert. Des Weiteren erfolgt in Kap.

Ames testing of direct black 38 parallels carcinogenicity testing

Journal of Applied Toxicology, 1981
AbstractStudies have established that Direct Black 38 and two other benzidine‐based dyes are carcinogenic. The carcinogenic effect has been generally considered attributable to the metabolic release of benzidine from Direct Black 38 and similar dyes. However, Ames tests indicated that when Direct Black 38 is reduced with sodium dithionate it is more ...
