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.

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.

Mid-infrared imaging and spectroscopy of the enigmatic cocoon stars in the Quintuplet Cluster [PDF]

, 2000
In an attempt to determine the nature of the enigmatic cocoon stars in the Quintuplet Cluster, we have obtained mid-infrared imaging and spectrophotometry of the cluster, using the CAM and SWS instruments on ISO, using SpectroCam-10 on the Palomar 5m ...

Photopolymerized Mixed Matrix Membranes for Liquid Organic Hydrogen Carrier Separation

Advanced Science, EarlyView.
Photopolymerized membranes with high metal organic framework (MOF)/Pd activated carbon loading enable selective separation of hydrogen‐rich/lean liquid organic hydrogen carriers (LOHCs) under mild operational conditions. The employed fabrication approach yields stratified, multilayer structures with enhanced aromatic/aliphatic (toluene ...

A z=5.34 Galaxy Pair in the Hubble Deep Field [PDF]

, 1998
We present spectrograms of the faint V-drop (V(606) = 28.1, I(814) = 25.6) galaxy pair HDF3-951.1 and HDF3-951.2 obtained at the Keck II Telescope. Fernandez-Soto, Lanzetta, & Yahil (1998) derive a photometric redshift of z(ph) = 5.28 (+0.34,-0.41; 2 ...

An Injectable Zwitterionic Hydrogels with Multiple Intermolecular Interactions for Effective Prevention of Abdominal Adhesions

Advanced Science, EarlyView.
An injectable PSA‐ZnO through multiple intermolecular including hydrogen bonds and electrostatic interactions for effectively prevents abdominal adhesions. The PSA‐ZnO hydrogel demonstrates superior wound healing promotion (≥ 95%) and more effective inhibition of scar formation compared to the commercial 3M dressing (≈80%), and prevents post‐operative ...

Laser Irradiation of Carbonaceous Chondrite Simulants: Space-weathering Implications for C-complex Asteroids

The Planetary Science Journal
Surfaces of carbonaceous asteroids (C-complex) have shown diverse, contrasting spectral variations, which may be related to space weathering. We performed laser irradiation experiments on CI and CM simulant material under vacuum to mimic the spectral ...
