Microwave‐Activated Bacterial Biorobot for Multimodal Cancer Therapy

Advanced Science, EarlyView.
An Escherichia coli bacterial biorobot is engineered for localized microwave activation in cancer therapy. Upon activation at tumor sites, the biorobot releases glucose oxidase, inducing tumor cell death via glucose depletion and H2O2 generation catalyzed by Cu2O.

Infrared Spectrophotometry as a Means for Identification of Mosquitoes.

Experimental Biology and Medicine, 1953
SummaryCrude aqueous extracts of Culex molestus, Culex quinquefasciatus, and Aedes aegypti adult mosquitoes were identified by infrared spectrophotometry. The most important differences were the relative intensities of the peaks at about 6.95 and 7.2 μ, and the relative depth and shape of the broad band from about 8.6 to 10 μ.

PD‐L1‐Targeting Biomimetic Photoresponsive Thermosensitive Liposomes for Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Tan et al. developed a platelet membrane‐coated, thermoresponsive liposome for targeted, light‐controlled delivery of fluorinated peptides that promotes programmed death‐ligand 1 degradation, induces tumor immunogenic cell death, suppresses solid tumors and metastases, and triggers durable immune memory, offering a promising strategy for peptide‐based ...

Observations of convection in A-type stars [PDF]

, 2004
Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from A-type stars. The recent theoretical advancements in convection modelling have proved a challenge to the observers to obtain measurements with sufficient

The Sirt1‐Piezo1 Axis Promotes Bone Formation and Repair in Mice

Advanced Science, EarlyView.
Piezo1 upregulates in cartilage callus during bone repair, where its deletion impairs ossification and healing in mice, while activation enhances these processes. Sirt1 positively regulates Piezo1 expression and activity to promote osteogenesis and bone repair in mice.

An infrared-submillimeter study of star-forming regions selected by the ISOSS 170um survey

, 2008
Using the ISOPHOT Serendipity Survey (ISOSS) at 170um a sample of galactic star-forming regions exhibiting very cold dust temperatures (< 20 K) and high masses (> 100 M_sun) has been established.

Four nearby L dwarfs [PDF]

, 1999
We present spectroscopic, photometric and astrometric observations of four bright L dwarfs identified in the course of the 2MASS near-infrared survey. Our spectroscopic data extend to wavelengths shortward of 5000\AA in the L0 dwarf 2MASSJ0746+2000 and ...

T1WI‐SWI Dual Modal Magnetic Resonance Nanoprobes for Accurate Diagnosis of Early Stage Alzheimer's Disease

Advanced Science, EarlyView.
We developed a smart MRI nanoprobe targeting BACE1 and Aβ plaques. It crosses the blood‐brain barrier. Upon encountering BACE1, the probe is cleaved, enabling T1WI imaging detection. Subsequent reaction with ONOO− induces probe aggregation, enhancing magnetic susceptibility for sensitive SWI imaging of Aβ plaques.

Mechanically Active Hydrogel for Healing Intestinal Fistulas through the YAP‐Mediated Mechanosensitization of Intestinal Epithelial Cells

Advanced Science, EarlyView.
This study develops the hydrogel with antimicrobial, adhesive, degradable, injectable, and temperature‐sensitive contraction properties based on the transcriptomic and pathological characteristics of intestinal fistula patients. This hydrogel can seal rabbit intestinal fistula in situ, reduce the intestinal defect, and promote intestinal epithelial ...
