Pathogen‐Centric Activation of an Azoreductase‐Responsive Antibody‐Antibiotic Conjugate for the Targeted Eradication of MRSA

open access: yesAdvanced Science, EarlyView.
A pathogen‐centric antibody‐antibiotic conjugate (AZO‐AAC) releases antibiotics via bacterial azoreductase, independent of host‐lysosomal function. This mechanism achieves nanomolar eradication of both planktonic and intracellular methicillin‐resistant Staphylococcus aureus (MRSA).

Lighting up Macrophage Reprogramming Assists Immunosuppressive Niche Modulation in Primary Tumors and Tumor‐Draining Lymph Nodes of Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study develops an intelligent NIR‐II‐responsive nanoplatform to combat immunosuppression in breast cancer. It enables real‐time visualization of macrophage activity via “off‐on” fluorescence while simultaneously reprogramming macrophages through the CSF‐1R and CD47‐SIRPα pathways.

DECOLONIZATION AND ECONOMIC GROWTH: THE CASE OF AFRICA [PDF]

open access: yes
This paper examines growth rates of real GDP per capita during decolonization in sub-Saharan Africa. For each period considered, I divide the sample between those countries that gained independence during the period and those that either remained ...

Colonization of Arabidopsis seedlings with GFP-expressing SA187 visualized by confocal microscopy.

open access: yes, 2018
(A) Root colonization of agar-grown seedlings starts in the elongation zone. Large colonies then occur in the differentiation zone. MIP; bar = 100 μm. (B) Colonies first established themselves in grooves between root epidermal cells. MIP; bar = 10 μm. (C)

H2S‐Amplified “Three‐in‐One” Antibacterial Strategy for Periodontitis Treatment Using a Photosensitive Pillararene‐Embedded COF/MOF Hybrid

open access: yesAdvanced Science, EarlyView.
The integration of ROS‐generating systems with H2S depletion strategies effectively overcomes the limitations imposed by endogenous antioxidant defenses on ROS‐based antimicrobial therapies. In this study, the Cu‐MOF is incorporated into pillararene‐embedded COF, achieving a “three‐in‐one” antimicrobial effect that markedly alleviated periodontal ...

Triple‐Negative Breast Cancer Cells Utilize IL8 and CXCL1 to Suppress NK Cells’ Function and Facilitate Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
Triple‐negative breast cancer (TNBC) cells evade natural killer (NK) cell immunity by secreting IL8 and CXCL1. These chemokines suppress NK cells’ function via CXCR1/2 and enhance cancer cells’ survival through PD‐L1 upregulation and BCL‐2 anti‐apoptotic signaling.

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes

open access: yesAdvanced Science, EarlyView.
In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...
