Intermittent hypoxia treatments cause cellular priming in human microglia

Journal of Cellular and Molecular Medicine, Volume 27, Issue 6, Page 819-830, March 2023., 2023
Abstract Obstructive sleep apnoea syndrome (OSAS) is a sleep‐disordered breathing characterized by nocturnal collapses of the upper airway resulting in cycles of blood oxygen partial pressure oscillations, which lead to tissue and cell damage due to intermittent hypoxia (IH) episodes.

Catalytic Reductive Alcohol Etherifications with Carbonyl‐Based Compounds or CO2 and Related Transformations for the Synthesis of Ether Derivatives

ChemSusChem, Volume 14, Issue 18, Page 3744-3784, September 20, 2021., 2021
Reductive etherification: Carbonyl‐based compounds and CO2 are employed as alkyl sources in alcohol reductive etherifications using external reducing agents (Si−H reagents or H2). By applying such protocols, an extensive range of symmetrical/asymmetrical ether derivatives with a high structural complexity can be efficiently produced.

Genetic depletion of Polo‐like kinase 1 leads to embryonic lethality due to mitotic aberrancies

BioEssays, Volume 38, Issue S1, Page S96-S106, July 2016., 2016
Two different mouse strains, a classical gene‐trapping KO and a conditional KO by Cre recombinase excision, demonstrate that the mitotic kinase Plk1 is essential at any stage of the embryonic development, and its depletion leads to mitotic aberrancies and embryonic death. Instead, Plk1 haploinsufficient mice do not show any alteration. Polo‐like kinase

In Vitro Manganese Exposure Disrupts MAPK Signaling Pathways in Striatal and Hippocampal Slices from Immature Rats

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
The molecular mechanisms mediating manganese (Mn)‐induced neurotoxicity, particularly in the immature central nervous system, have yet to be completely understood. In this study, we investigated whether mitogen‐activated protein kinases (MAPKs) and tyrosine hydroxylase (TH) could represent potential targets of Mn in striatal and hippocampal slices ...
