The 3‐Hit Metabolic Signaling Model for Autism Spectrum Disorder: A Summary

open access: yesAutism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a highly heritable yet environmentally sensitive neurodevelopmental condition whose biological heterogeneity has resisted a unifying causal explanation for over 100 years. The 3‐hit metabolic signaling model proposes that ASD arises from abnormal persistence of an evolutionarily conserved stress‐response ...

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

open access: yesChemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
