FeDSNP‐Pa Nanoassemblies: A Triple‐Action Therapeutic Strategy Targeting Oxidative Stress, Inflammation, and Pyroptosis for Retinal Ganglion Cell Protection in Glaucoma

Advanced Functional Materials, EarlyView.
FeDSNP‐Pa, a metallized nanoparticle loaded with sodium pyruvate (Pa), exerts triple therapeutic effects by scavenging reactive oxygen species (ROS), suppressing inflammatory responses, and inhibiting pyroptosis signaling pathways. This multifunctional neuroprotective strategy protecting retinal ganglion cells (RGCs) from elevated intraocular pressure ...

Response of the Land‐Atmosphere System Over North‐Central Oklahoma During the 2017 Eclipse

Geophysical Research Letters, 2018
On 21 August 2017, a solar eclipse occurred over the continental United States resulting in a rapid reduction and subsequent increase of solar radiation over a large region of the country.

The ionospheric responses to the 11 August 1999 solar eclipse: observations and modeling [PDF]

Annales Geophysicae, 2008
A total eclipse occurred on 11 August 1999 with its path of totality passing over central Europe in the latitude range 40°–50° N. The ionospheric responses to this eclipse were measured by a wide ionosonde network.

Meteorological impacts of the total solar eclipse of 21 August 2017 [PDF]

, 2018
A solar eclipse presents many opportunities for examining the impact of the reduction in solar radiation upon meteorological conditions, particularly so as accurate predictions of the circumstances and extent of the eclipse well before the event enable ...

Synergistic Osteogenesis After Co‐Administration of cmRNAs Encoding BMP‐2 and BMP‐7 Utilizing a Transcript‐Activated Matrix

Advanced Functional Materials, EarlyView.
This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...

Natural Coronagraphic Observations of the Eclipsing T Tauri System KH 15D: Evidence for Accretion and Bipolar Outflow in a WTTS

, 2003
We present high resolution (R $\sim$ 44,000) UVES spectra of the eclipsing pre-main sequence star KH 15D covering the wavelength range 4780 to 6810 {\AA} obtained at three phases: out of eclipse, near minimum light and during egress. The system evidently

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

Advanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Bicontinuous Microarchitected Scaffolds Provide Topographic Cues That Govern Neuronal Behavior and Maturation

Advanced Functional Materials, EarlyView.
A scalable biomimetic platform transforms bioinert poly(ethylene glycol) diacrylate into neuroinstructive matrices via integrating solvent transfer‐induced phase separation, microfluidics, and 3D bioprinting. Bicontinuous, hyperbolically curved microporous networks embedded within a fibrous construct elicit rapid adhesion, robust proliferation, and ...

A cyclical period variation detected in the updated orbital period analysis of TV Columbae [PDF]

, 2010
The two CCD photometries of the intermediate polar TV Columbae are made for obtaining the two updated eclipse timings with high precision. There is an interval time \sim 17yr since the last mid-eclipse time observed in 1991.

Removal of Steroid Hormone Micropollutants by an Electrochemical Carbon Nanotube Membrane Flow‐Through Reactor: Role of Concentration and Degradation Mechanisms

Advanced Functional Materials, EarlyView.
A flow‐through electrochemical membrane reactor equipped with a carbon nanotube membrane eliminates the mass transfer limitation, achieving removals >97.5% for steroid hormone (SH) micropollutants through electrochemical adsorption and degradation, over a broad initial concentration varying from 50 to 106 ng L−1.
