Inorganic Nanomaterials can Promote or Inhibit Tumor Metastasis Depending on Tumor Microenvironment Composition

open access: yesAdvanced Science, EarlyView.
As engineered nanomaterials gain prominence in cancer imaging and therapy, understanding their impact on tumor progression becomes increasingly critical. We demonstrate that gold and silica‐coated gold nanomaterials can either suppress or enhance breast cancer metastasis through distinct tumor microenvironment interactions, while identifying ...

One‐Step Immobilized Phage Depolymerase Coatings for Catheter‐Related Bloodstream Infections

open access: yesAdvanced Science, EarlyView.
Catheter‐related bloodstream infections (CRBSI) caused by drug‐resistant Gram‐negative bacteria remain a major clinical challenge. Here, a polydopamine‐assisted depolymerase coating degrades bacterial capsules and restores serum‐mediated killing, effectively suppressing biofilms and reducing bacterial burden in vitro, ex vivo, and in vivo, presenting a

LB-MAC: A Lifetime-Balanced MAC Protocol for Sensor Networks [PDF]

open access: yes, 2012
This paper presents LB-MAC, a new MAC protocol for asynchronous, duty cycle sensor networks. Different from existing sensor network MAC protocols that usually focus on reducing energy consumption and extending lifetime of individual sensor nodes, LB-MAC aims at prolonging the network lifetime through balancing the nodal lifetime between neighboring ...

Intrasplenic Thymus Organogenesis from Injectable Tissue Fragments Restores Functional T‐Cell Immunity

open access: yesAdvanced Science, EarlyView.
Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

Macrophage PABPC4‐SPP1 Axis Orchestrates Immunosuppression in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
In the CRC microenvironment, macrophage PABPC4 binds to the 3′UTR of SPP1 mRNA to stabilize its expression, thereby sustaining M2‐like immunosuppressive macrophage polarization. Concurrently, this axis suppresses CD8+ T cell effector functions via CD44 signaling, collectively fostering an immunosuppressive niche that drives tumor progression.

Energy-Efficient Reservation-Based Medium Access Control Protocol for Wireless Sensor Networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
In Wireless Sensor Networks (WSNs), a robust and energy-efficient Medium Access Control (MAC) protocol is required for high energy efficiency in harsh operating conditions, where node and link failures are common.

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

open access: yesAdvanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

Macrophage PARP7 Alleviates Septic Cardiomyopathy by Interacting With TBK1 and Suppressing TBK1‐Driven Inflammatory Response

open access: yesAdvanced Science, EarlyView.
In septic cardiomyopathy, PARP7 directly binds TBK1 and mediates its ADP‐ribosylation, thereby repressing TBK1‐driven proinflammatory signaling in macrophages. ABSTRACT Septic cardiomyopathy is a life‐threatening complication of sepsis, and an uncontrolled inflammatory response represents a key pathogenic mechanism. PARP7 negatively regulates the IFN‐I
