Stabilisation of LDPE cross-linked in the presence of peroxides III. Mass spectrometric study of chemical changes taking place in the n-octadecane–di…

Abstract An attempt was made to identify the products of the reaction between dicumyl peroxide and Irganox 1081, carried out in n -octadecane (saturated hydrocarbon), in conditions of fast decomposition of the peroxide (180°C, 5 min). Mass spectrometry (MS) was employed to find m/z values of molecular and fragment ions in analyses of the components ( n -octadecane, dicumyl peroxide, Irganox 1081) and of the following systems: n -octadecane–dicumyl peroxide, n -octadecane–Irganox 1081 and n -octadecane–dicumyl peroxide–Irganox 1081, after holding them at a temperature of 180°C for 5 min. The tendency of sulphur in Irganox 1081 to oxidise, specifically in the presence of dicumyl peroxide, was…

Neurodegenerative diseases are characterized by oxidative stress associated with mitochondrial damages leading to neuronal cell death. To mitigate these damages and promote neuronal cytoprotection and neurogenesis, endogenous (Neuropeptide: octadecaneuropeptide (ODN)) or exogenous (Polyphenols: resveratrol (RSV) and apigenin (API)) natural neurotrophic factors could be used as therapeutic agents to promote neuronal differentiation of immature and pluripotent stem cells. ODN is a peptide produced by astrocytes and known as a powerful neuroprotective agent. It is therefore of interest of studying its effects on the mobilization of calcium, its ability to protect neuronal cells against apoptos…

The Shwartzman reaction repealed

2007

The article, “ -Galactosylceramide induces protection against lipopolysaccharide-induced shock” (doi:10.1189/jlb.0506298), was selected as a Pivotal Advance because the results suggest that -galactosylceramide ( GalCer), a glycolipid isolated from marine sponges, can protect against the complete morbidity and mortality characterisitic of endotoxin shock by inducing NKT cells to produce TH2 cytokines.
