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.

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

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 ...

Microbial Purification of Postfermentation Medium after 1,3‐PD Production from Raw Glycerol
BioMed Research International, Volume 2013, Issue 1, 2013., 2013 1,3‐Propanediol (1,3‐PD) is an important chemical product which can be used to produce polyesters, polyether, and polyurethanes. In the process of conversion of glycerol to 1,3‐PD by Clostridium large number of byproducts (butyric, acetic and lactic acid) are generated in the fermentation medium.
