Identification of the direct regulon of NtcA during early acclimation to nitrogen starvation in the cyanobacterium Synechocystis sp. PCC 6803
(Oxford University Press, 2017)
In cyanobacteria, nitrogen homeostasis is maintained by an intricate regulatory network around transcription factor NtcA. Although mechanisms controlling NtcA activity appear to be well understood, its regulon remains ...

Nanocrystallization Kinetics Understood as Multiple Microprocesses Following the Classical Theory of Crystallization
(Elsevier, 2016)
In this work, we propose a model for using the classical Johnson-Mehl-Avrami-Kolmogorov (JMAK) crystallization theory to analyze nanocrystallization processes as a set of multiple microprocesses. This model is based on the ...

Accurate determination of the stiffness properties for an elastic interface under peeling conditions between homogeneous materials
(Elsevier, 2022-04)
In this paper, several models for analysing peeling tests are considered, including numerical models based on FEM, semi-analytical approaches, and beam models including an elastic interface. Results show that none of the ...

Adaptation of Salmonella enterica to bile: essential role of AcrAB-mediated efflux
(Society for Applied Microbiology, 2018)
Adaptation to bile is the ability to endure the lethal effects of bile salts after growth on sublethal concentrations. Surveys of adaptation to bile in Salmonella enterica ser. Tyhimurium reveal that active efflux is ...

Paving the Way to Establish Protocols: Modeling and Predicting Mechanochemical Reactions
(American Chemical Society, 2021)
Parametrization of mechanochemical reactions, or relating the evolution of the reaction progress to the supplied input power, is required both to establish protocols and to gain insight into mechanochemical reactions. Thus, ...

On the 3D extension of failure models for adhesive joints under mixed-mode fracture conditions: LEBIM and CZM
(Elsevier, 2019-04)
Interface models for triggering damage events have been extensively used in many engineering applications due to their inherent versatility and relatively simple numerical implementations. Usually, the non-linear behavior ...

Galectin‑3, a novel endogenous TREM2 ligand, detrimentally regulates infammatory response in Alzheimer’s disease
(Springer, 2019)
Alzheimer’s disease (AD) is a progressive neurodegenerative disease in which the formation of extracellular aggregates of amyloid beta (Aβ) peptide, fibrillary tangles of intraneuronal tau and microglial activation are ...

A New Peracetylated Oleuropein Derivative Ameliorates Joint Inflammation and Destruction in a Murine Collagen-Induced Arthritis Model via Activation of the Nrf-2/Ho-1 Antioxidant Pathway and Suppression of MAPKs and NF-κB Activation
(MDPI, 2021-01)
Oleuropein (OL), an olive tree secoiridoid and its peracetylated derivate (Per-OL) haveexhibited several beneficial effects on LPS-stimulated macrophages and murine experimental sys-temic lupus erythematosus (SLE). This ...

Solvent-free synthesis of quaternary alpha-hydroxy alpha-trifluoromethyl diazenes: the key step of a nucleophilic formylation strategy
(Royal Society of Chemistry, 2016)
An efficient, scalable and operationally simple one-pot, 2-step strategy for the nucleophilic formylation of trifluoromethyl ketones is presented. The key step is an unprecedented diaza-carbonyl-ene reaction of formaldehyde ...

Tensile and shear strength of bimaterial interfaces within composite materials
(Elsevier, 2016-03)
The determination of the tensile and shear strengths of homogeneous materials can be easily performed by standard tensile and shear (e.g. Iosipescu) tests. Nevertheless, when the determination of these strengths involves ...
