New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids. [PDF]

J Appl Toxicol
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Design of an Adaptive Control to Feed Hydrogen‐Enriched Ethanol‐Gasoline Blend to an Internal Combustion Engine

International Journal of Chemical Engineering, Volume 2022, Issue 1, 2022., 2022
In this work, an internal combustion (IC) engine air‐fuel ratio (AFR) control system is presented and evaluated by simulation. The control scheme aims to regulate the overall air‐fuel ratio (AFRoverall) in an IC engine fueled with a hydrogen‐enriched ethanol‐gasoline blend (E10) as fast as possible.

Calibration of non‐catching precipitation measurement instruments: A review

Meteorological Applications, Volume 28, Issue 3, May/June 2021., 2021
Non‐catching type gauges are the emerging class of in situ precipitation measurement instruments. For these instruments, no agreed testing and calibration methodology exists, and the adopted procedures are rarely traceable to internationally recognized standards.

Metabolomic Evaluation of Chronic Periodontal Disease in Older Adults

Mediators of Inflammation, Volume 2021, Issue 1, 2021., 2021
Periodontal disease is an infectious inflammatory disease related to the destruction of supporting tissues of the teeth, leading to a functional loss of the teeth. Inflammatory molecules present in the exudate are catalyzed and form different metabolites that can be identified and quantified.
