Porphyromonas gingivalis is a key bacterium in chronic periodontitis, which associated with several inflammatory diseases. Lipopolysaccharides from P. (Pg LPS) can activate multiple cell types via the production of pro-inflammatory cytokines. The receptors for Pg LPS have initially been reported as TLR2, contrasting well-studied TLR4 receptor E. coli LPS; this observation remains controversial since synthetic lipid A activates but not TLR2. Despite observation, dogma LPS-mediated TLR2...

Abstract Coronavirus disease 2019 (COVID-19) pandemic is affecting millions of patients worldwide. The consequences initial exposure to SARS-CoV-2 go beyond pulmonary damage, with a particular impact on lipid metabolism. Decreased levels in HDL-C were reported COVID-19 patients. Since HDL particles display antioxidant, anti-inflammatory and potential anti-infectious properties, we aimed at characterizing proteome functionality during relative healthy subjects. HDLs isolated from plasma 8...

Metabolic disorders related to obesity and type 2 diabetes are associated with aggravated cerebrovascular damages during stroke. In particular, hyperglycemia alters redox inflammatory status, leading cerebral endothelial cell dysfunction, blood-brain barrier (BBB) disruption brain homeostasis loss. Polyphenols constitute the most abundant dietary antioxidants exert anti-inflammatory effects that may improve complications in This study evaluated of characterized polyphenol-rich extract...

Abstract The fluorescence spectrum of 4-cyanobiphenyl, 4-cyano-4'-propyloxybiphenyl, 4-cyano-4'-octylbiphenyl and 4-cyano-4'-octyloxybiphenyl has been analyzed as a function solvent polarity solute concentration. originates from the planar 1 L state polarized along long axis molecule. A red shift emission loss vibrational structure is observed by increasing in fluid solution but these effects are absent glassy ethanol at 77°K. This assigned to an orientation relaxation process cage electric...

Abstract Main chain scission yields G s are, respectively, 0.88 and 2.6 for polymethylmethacrylate (PMM) irradiated at 77 313°K. values volatile products (mainly CH 4 , CO, CO 2 HCOOCH 3 ) were measured. The ratio of methyl containing volatiles to main yield is about one both temperatures. In the presence ethylmercaptan, very efficient protection observed whereas amount little or not affected. These results show that side breaking are closely related former process precedes induces latter. A...

Metabolic disorders are risk factors for stroke exacerbating subsequent complications. Rapidly after brain injury, a glial scar forms, preventing excessive inflammation and limiting axonal regeneration. Despite the growing interest in wound healing following formation of context metabolic is poorly documented. In this study, we used db/db mice to investigate impact perturbations on repair mechanisms, with focus scarring. First, confirmed development obesity, poor glucose regulation,...

SARS-CoV-2 infection goes beyond acute pneumonia, as it also impacts lipid metabolism. Decreased HDL-C and LDL-C levels have been reported in patients with COVID-19. The profile is a less robust biochemical marker than apolipoproteins, components of lipoproteins. However, the association apolipoprotein during COVID-19 not well described understood. objective our study to measure plasma 14 apolipoproteins evaluate relationships between levels, severity factors patient outcomes.

The global fight against pandemics is a major public health issue. Epidemiological studies showed reduced risk of the coronavirus disease 2019 (COVID-19) severity with practice regular physical activity (PA) in clinical populations. Here, we investigated effect PA COVID-19 young general population. Methods: Two hundred ninety volunteers over 18 years old from Reunion Island responded to an online survey concerning sociodemographic, lifestyle and information. Daily was studied using...
