The Maize ZmbHLH118 Transcription Factor Regulates Vacuolar Nitrate Loading by the NO3− Transporter ZmCLCa

open access: yesAdvanced Science, EarlyView.
In maize, the bHLH transcription factor ZmbHLH118 directly binds to the promoter of ZmCLCa and inhibits its expression. Tonoplast‐localized ZmCLCa mediates NO3− influx into the vacuole to regulate intracellular NO3− homeostasis, modulating nitrate uptake and metabolism, plant growth, and grain yield.

A Microfiber‐Reinforced Janus Hydrogel E‐Skin With Recyclable Feature for Multimodal Sensing and Gender‐Specific Physiological Monitoring

open access: yesAdvanced Science, EarlyView.
Hydrogel‐based wearable electronics hold great promise for physiological monitoring in privacy‐sensitive regions. In this study, a polyurethane (PU) microfiber‐reinforced gelatin hydrogel e‐skin is developed, boasting multiple advantages such as ultra‐thinness, high toughness, and long‐term skin conformability.

Self‐Adaptive Allantoin@ZIF8 Nanocomposite Hydrogel with Resveratrol Synergy for MRSA‐Infected Wound Regeneration

open access: yesAdvanced Science, EarlyView.
Based on allantoin‐loaded ZIF8 nanoparticles (Alla@ZIF8) and methacrylated quaternary ammonium carboxymethyl chitosan/resveratrol composite hydrogels (RMQCC), an adaptive multifunctional hydrogel system (Alla@ZIF8‐Gel) was constructed and confirmed to induce the healing of MRSA‐infected wounds via suppressing bacterial proliferation, alleviating ...

An Implantable Scaffold Sequentially Releasing STING Agonist and B7‐H3 Antibody for Bone Metastasis Immunotherapy

open access: yesAdvanced Science, EarlyView.
We developed an implantable dual‐drug depot using GelMA for bone metastasis treatment, co‐delivering MSA‐2 and αB7‐H3‐loaded CaCO3 microparticles. Sustained release from GelMA scaffold enables MSA‐2 to activate STING signaling and enhance T‐cell infiltration and activation, while sequentially released αB7‐H3 blocks MSA‐2‐induced B7‐H3 upregulation ...

Du scripturaire à l'indiciel : texte, photographie, document

open access: yes, 1993
With the advent of photography, comes the first fracture of a symbolic order which threatens the mediological authority of text. Matrix and symptom of an index paradigm that changes our experience of presence, memory and relationship, photography opens a new economy of signs, which has not only deployed outside the scriptural domain, but also inside.

Asymmetric Cu─N─Ru Bridgedsite Nanozyme‐Loaded Injectable Thermogel Boosts Cuproptosis‐Like Death for Multidrug‐Resistant Urinary Tract Infections

open access: yesAdvanced Science, EarlyView.
To address multidrug‐resistant urinary tract infections (MDR‐UTIs), we developed Cu‐ZIF8‐Ru nanozyme featuring an asymmetric Cu─N─Ru catalytic site. This unique structure enhances multienzyme‐mimetic activity, eradicating resistant bacteria by inducing a cuproptosis‐like death pathway through intracellular Cu2+ accumulation and energy depletion.

Thermal Cyclotrimerization Bridges Polymer‐Filler Interfaces for High‐Performance CO2 Separation Membranes

open access: yesAdvanced Science, EarlyView.
Thermal cyclotrimerization of nitriles converts interfacial discontinuity in MAF‐stu‐1/PIM‐1 MMMs into a continuity‐enhanced junction. Triazine–Zn2+ coordination between TR‐PIM chains and MAF‐stu‐1, together with hydrogen bonding and π–π stacking, lowers interfacial tension and builds selective CO2 pathways, enabling > 10 000 barrer CO2 permeability ...

The photography document : an art of time ?

open access: yes, 2008
A l’origine la sociologie se définit comme une science, pour étayer sa posture elle a mis au point des méthodes structurées, dont la photographie a fait parti. Dans la tradition du XIXe siècle l’image photographique est un outil scientifique abondamment utilisé pour ses qualités objectives et documentaires. Comme on va le voir ce caractère scientifique

Dysregulation of the PATZ1/CTCF Balance Silences ZBTB20 to Drive Melanoma Progression

open access: yesAdvanced Science, EarlyView.
This study uncovers a new oncogenic mechanism in melanoma. The transcription factor PATZ1 competes with the architectural protein CTCF for DNA binding, thereby disrupting a specific chromatin loop and silencing the tumor suppressor ZBTB20. This event unleashes the pro‐tumorigenic PMEPA1‐p38‐STAT1 signaling axis, promoting cancer progression.
