The E3 Ubiquitin Ligase RLIM Safeguards Oligodendrocyte Development and Myelination by Targeting SLC7A11 for Polyubiquitination to Regulate Ferroptotic Resistance

Advanced Science, EarlyView.
RLIM‐mediated SLC7A11 polyubiquitination is required for SPTBN2‐mediated trafficking and membrane localization of SLC7A11, which enables oligodendrocyte precursor cells to be resistant to ferroptosis and safeguards oligodendrocyte lineage progression and thus myelination.

Intrinsic Dual‐Phase Regulated GeSe2 Nanoparticles Triggered by Ball‐Milling Treatment for Photonic Multi‐Valued Logic Circuits

Advanced Science, EarlyView.
We report the solid‐state ball milling, a traditional, reliable, mass‐productive material processing, to prepare the air‐stable and dual‐phase GeSe2‐x nanoparticles with extended photodetection feasibility toward optical‐wavelength regions. We further display photonic multi‐valued logic (MVL) circuit through the employment of a hybrid PMMA/GeSe2‐x ...

Liver Endothelia Orchestrate MASH‐Associated Macrophage Zonation Through FSTL1‐ITGA4 Axis

Advanced Science, EarlyView.
Liver inflammation in MASH fundamentally hinges on the newly defined Kit/STAT2/FSTL1/ITGA4 axis. Declining endothelial Kit collapses normal hepatic zonation, driving an aberrant FSTL1 gradient that recruits pathogenic macrophages. Strikingly, targeting FSTL1‐ITGA4 with anti‐VLA4 restores spatial immune homeostasis and halts disease progression ...

GUNS BEFORE POLITICS

Scientia Militaria, 2012
'What we must stop is a situation where the gun is a means of promotion, a machine gun a way of applying pressure, a tank becomes government policy.' This was the despairing cry of an African lawyer during yet another recent military intervention in that

Inhalable ROS‐Responsive Nanospray Activates PPAR‐γ to Restore Macrophage Mitochondrial Homeostasis and Attenuate Radiation‐Induced Lung Injury

Advanced Science, EarlyView.
A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

Unipolaridade, governabilidade global e intervenção unilateral anglo-americana no Iraque

Revista Brasileira de Política Internacional, 2004
As intervenções humanitárias (Bósnia 1995-2003, Somália 1992-1993, Kosovo 1999-2003) e de substituição de regimes ditatoriais (Haiti 1994, Afeganistão 2001-2003, Iraque 2003) na política internacional têm sido objeto de muitas controvérsias acadêmicas ...

Gut Microbial Release of Ferulic Acid From Germinated Quinoa Alleviates Obesity‐Associated Cognitive Impairment by Activating Hippocampal Mitophagy Associated with PINK1/Parkin Pathway

Advanced Science, EarlyView.
Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

External Interventions and Civil War Intensity in South-Central Somalia (1991-2010)

Cadernos de Estudos Africanos, 2014
External interventions in conflicts are prescribed to be peace-promoting mechanisms, but their effects seldom de-escalate conflict intensity. Based on the balance of capabilities theory, this paper tests the effects that the type of intervention ...
