Pensando el arte y la sociedad contemporáneos: la recepción del concepto benjaminiano de aura en Bourriaud y Michaud

open access: yesRevista Filosofía UIS, 2009
El artículo se propone pensar la cuestión del arte en la actualidad y su relación con lo político tomando como hilo conductor el concepto benjaminiano de aura y, en particular, sus reinterpretaciones contemporáneas en las obras de Nicolas Bourriaud e ...

Entropy Decoding the Fundamental Law of Phase Competition in Glass Formation

open access: yesAdvanced Science, EarlyView.
We validate the integration of intermetallic and eutectic phases as initial phases for composition design. The phase competition mechanism in glass formation is quantitatively clarified based on the melting entropy of competing phases. Glass‐forming ability is modulated by tuning phase competition via the melting entropy of initial phases.

Ni liquidation, ni restauration de l’aura. Benjamin, Pasolini et le cinéma

open access: yesAppareil, 2009
Puisant dans la réflexion de Benjamin les éléments permettant de penser un passage des formes traditionnelles de narration à d’autres formes, contemporaines et susceptibles d’être accueillies au sein de l’appareil cinématographique lui-même, cet article ...

Robust Amorphous MOF‐Based Aerogels Digital Biosensor for Sensitive Detection of Organophosphate Pesticides

open access: yesAdvanced Science, EarlyView.
We report a robust aerogel digital biosensor by integrating an enzyme‐mediated amorphous MOF within an aerogel matrix for on‐site pesticide detection. The enzyme‐mediated assembly strategy enables in situ tailoring of MOF into a porous amorphous structure, achieving both high stability and activity.

Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Surfaceome Reprogramming of Stemsomes Promotes Lung Cancer Targeting via Potentiated Receptor–Ligand Interactions

open access: yesAdvanced Science, EarlyView.
This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.

Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

open access: yesAdvanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Auras do Professar: desterritorialização da autoridade no sentido da communitas e do entusiasmo

open access: yesRevista Brasileira de Estudos da Presença, 2020
O artigo caracteriza a autoridade docente como fruto da tradição patriarcal e cristã, na qual a performance do professor instaurava a disciplina e o silêncio. Mas, tal como a Aura da obra de arte entra em decadência pelo avanço técnico, o mesmo ocorreria

Single‐Cell Reveal GALNT7‐Dependent Ferroptosis Suppression as a Mechanism of Immunotherapy Resistance in Non‐Small Cell Lung Cancer

open access: yesAdvanced Science, EarlyView.
Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,

Prolonged visual aura, late-onset migraine-like headaches, and seizures suggest an occipital arteriovenous malformation

open access: yesJournal of Family Medicine and Primary Care
To report a patient with occipital arteriovenous malformation (AVM), manifested by prolonged visual aura and migraine-like headache as well as rare tonic–clonic seizures. The patient is a 55-year-old woman with a left occipital, unruptured AVM that first
