Oral Celastrol Nanomedicine Targeting Intestinal Antigen‐Presenting Cells to Effectively Mitigate Autoimmune Uveitis via Gut‐Retina Axis

open access: yesAdvanced Science, EarlyView.
Oral nanoCEL exhibits effective intestinal targeting of antigen‐presenting cells and restores the Th17/Treg balance in lymph nodes and spleen, ultimately protecting the blood‐retinal barrier by inhibiting peripheral immune cell infiltration and suppressing retinal glial cell activation.

Local Advantage in a Global Era: Making Local Procurement Work for New York [PDF]

open access: yes, 2007
Around the country municipalities have enacted local procurement preference laws, which give a competitive advantage to local firms bidding on public contracts. Much of this legislation has been informed by a broader “local first” movement. Those in this

ACSL1‐Dependent Microglial Lipoimmunometabolic Reprogramming Underlies Cognitive Deficits in Alcohol Use Disorder

open access: yesAdvanced Science, EarlyView.
This study reveals that chronic alcohol exposure selectively upregulates ACSL1 expression in prefrontal cortical microglia, driving lipid metabolism reprogramming and lipid droplet accumulation, which activates the NLRP3 inflammasome and sustains neuroinflammation. To reverse this process, a dual‐targeted lipid nanoparticle, siACSL1@LNP‐MR, is designed

Automated Transit Networks (ATN): A Review of the State of the Industry and Prospects for the Future, MTI Report 12-31 [PDF]

open access: yes, 2015
The concept of Automated Transit Networks (ATN) - in which fully automated vehicles on exclusive, grade-separated guideways provide on-demand, primarily non-stop, origin-to-destination service over an area network – has been around since the 1950s ...

Trackable Tolerogenic Macrophages Integrate PD‐L1 and Rapamycin Signaling to Suppress Alloimmune Responses in Transplantation

open access: yesAdvanced Science, EarlyView.
We developed a macrophage‐based therapeutic platform, termed trackable tolerogenic macrophages (TTM), for dual‐function immunomodulation and visualization in vivo. TTM cells were engineered to overexpress PD‐L1, incorporate bioorthogonal cell surface tags, and load rapamycin for sustained release.

3D‐Printed Ion‐Conductive Hydrogels with Tunable Mechanical–Electrical Properties for Multimodal Sign Language Recognition

open access: yesAdvanced Science, EarlyView.
This work successfully fabricated ion‐conductive hydrogels with low hysteresis and high conductivity using 3D printing technology. By adjusting the component ratios, the properties of the hydrogels can be tuned to meet diverse sensing requirements. Finally, a multimodal sensing sign language recognition system was constructed based on this hydrogel ...
