Études caribéennes, 2015 Cette réflexion propose d’étudier le luxe à travers une approche pluridisciplinaire, de la philosophie à la sociologie, de la psychologie à l’économie. Tout d’abord, il s’agit d’identifier les fondements de luxe avec les travaux de Veblen (consommation ostentatoire), de Bourdieu (distinction et habitus) et Lipovetsky (esthétisation), et de définir les ...

Advanced Science, EarlyView.Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

Advanced Science, EarlyView.LDHA‐driven lactate production in mesenchymal glioma stem cells promotes p300‐dependent H3K18 lactylation, activates USP30 transcription, and stabilizes MBOAT2 to remodel phosphatidylethanolamines toward ferroptosis‐resistant PE‐MUFA species. Disrupting this metabolic–epigenetic–lipid circuit enhances ferroptosis and sensitizes glioblastoma to ...

AI-2-dependent gene regulation in
BMC Microbiology, 2008 Background Autoinducer 2 (AI-2), a widespread by-product of the LuxS-catalyzed S-ribosylhomocysteine cleavage reaction in the activated methyl cycle, has been suggested to serve as an intra- and interspecies signaling molecule, but in many bacteria AI-2 ...

VlPAG/DRN Microglia Drive Neuropathic Pain‐Induced Depression via a Defined Neuroimmune Axis
Advanced Science, EarlyView.Peripheral nerve injury (SNI) induces neuropathic pain, activates midbrain microglia, and triggers an NLRP3–IL‐1β–dependent inflammatory cascade. IL‐1β signals through IL‐1R1 on vlPAG/DRN VGLUT2+ neurons (vlPAG/DRNGlu), inducing hyperexcitability and driving the vlPAG/DRNGlu→BNSTGABA circuit to produce the affective component of neuropathic pain ...

LuxS signaling in Porphyromonas gingivalis-host interactions
, 2015 Dental plaque is a multispecies biofilm in the oral cavity that significantly influences oral health. The presence of the oral anaerobic pathogen Porphyromonas gingivalis is an important determinant in the development of periodontitis.

Advanced Science, EarlyView.Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...
