Thermo-oxidative aging of bitumen
(Taylor and Francis Ltd., 2018-07-03)
Thermo-oxidative bitumen ageing has been commonly recognised as the main cause of asphalt cracking. The effect of thermo-oxidative ageing level on bitumen has been studied in this work by means of a simple and effective ...

OXIDES AS HETEROGENEOUS PROMOTERS FOR LIQUID-PHASE HYDROCARBONYLATION REACTIONS WITH IODOCARBONYLRUTHENIUM CATALYSTS
(Amer Chemical Soc, 1992-01-01)
Basic or acid oxides, used as heterogeneous promoters of carbonylruthenium catalysts in liquid-phase hydrocarbonylation reactions on oxygenated substrates, strongly affect the activity and selectivity of the catalytic ...

Liquid phase selective hydrogenation of cinnamaldehyde over copper supported catalysts
(Elsevier Science, 2012-01-31)
The selective hydrogenation of cinnamaldehyde is carried out in a batch reactor, at 100 °C and 1 MPa of H 2 using isopropyl alcohol as the solvent, over a series of copper supported catalysts: Cu/Al 2O 3, Cu/SiO 2 Cu/MCM-48, ...
Overreaching-induced oxidative stress, enhanced HSP72 expression, antioxidant and oxidative enzymes downregulation

Protection against oxidative stress in Escherichia coli stationary phase by a phosphate concentration-dependent genes expression
(Elsevier Science Inc, 2009-03)
Escherichia coli gradually decline the capacity to resist oxidative stress during stationary phase. Besides the aerobic electron transport chain components are down-regulated in response to growth arrest. However, we have ...
An intracerebroventricular injection of amyloid-beta peptide (1–42) aggregates modifies daily temporal organization of clock factors expression, protein carbonyls and antioxidant enzymes in the rat hippocampus
(Elsevier, 2021-09)
Alzheimer disease (AD) is the most frequent form of dementia in the elderly. It is characterized by the deterioration of memory and learning. The histopathological hallmarks of AD include the presence of extracellular ...
