Hydrogen Peroxide‐Responsive Aminoferrocene Prodrugs

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
To improve sensitivity toward H2O2, the boronic acid pinacol ester in known aminoferrocene‐based anticancer prodrug 13b is replaced with an α‐ketamide fragment to obtain prodrug 2a and some of its N‐alkylated derivatives. 2a exhibits substantially improved cytotoxicity in vitro toward ovarian cancer A2780 and Burkitt's lymphoma BL‐2 cells.

Shelf‐Life Enhancement of Sugarcane Juice With Herbal Extracts: Extracted Through Novel Microwave‐Assisted Drying Extraction Technique

open access: yesFood Safety and Health, EarlyView.
ABSTRACT Antioxidants in foods delay or prevent the oxidation of the food. Previously, synthetic antioxidants were commonly used in food formulations, but, due to safety concerns, interest in natural antioxidants has intensified. A novel microwave‐assisted drying extraction process was adopted to dry mint and coriander leaves.

Orthogonal Alignment of Galaxy Group Angular Momentum with Cosmic Filament Spines: An Observational Study

open access: yesThe Astrophysical Journal Letters
We investigated the alignment between the angular momenta of galaxy groups and the spines of their associated cosmic filaments. Our results demonstrate a significant tendency for these two orientations to be perpendicular, indicating that the rotation of

Observational Evidence for an Age Dependence of Halo Bias

open access: yes, 2006
We study the dependence of the cross-correlation between galaxies and galaxy groups on group properties. Confirming previous results, we find that the correlation strength is stronger for more massive groups, in good agreement with the expected mass ...

Scylla. II. The Spatially Resolved Star Formation History of the Large Magellanic Cloud Reveals an Inverted Radial Age Gradient

open access: yesThe Astrophysical Journal
The proximity of the Magellanic Clouds provides the opportunity to study interacting dwarf galaxies near a massive host, and spatial trends in their stellar population properties in particular, with a unique level of detail.

Fresh Activity in Old Systems: Radio AGN in Fossil Groups of Galaxies

open access: yes, 2012
We present the first systematic 1.4 GHz Very Large Array radio continuum survey of fossil galaxy group candidates. These are virialized systems believed to have assembled over a gigayear in the past through the merging of galaxy group members into a ...

Tumor desialylation surpasses anti‐PD‐L1 checkpoint therapy in restoring anti‐tumor immunity in a murine model for colorectal cancer

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Our research highlights how tumor sialylation affects tumor growth and reshapes the immune tumor microenvironment in colorectal cancer. We demonstrate for the first time that complete removal of sialic acids from colorectal tumor cells elicits a robust anti‐tumor immune response, but does not enhance anti‐PD‐L1 blockade efficacy.

HST Proper Motion of Andromeda III. Another Satellite Coorbiting the M31 Satellite Plane

open access: yesThe Astrophysical Journal
We measure the absolute proper motion of Andromeda III (And III) using Advanced Camera for Surveys/Wide Field Channel and WFPC2 exposures spanning an unprecedented 22 yr time baseline.

Galaxy-galaxy(-galaxy) lensing as a sensitive probe of galaxy evolution

open access: yes, 2012
The gravitational lensing effect provides various ways to study the mass environment of galaxies. We investigate how galaxy-galaxy(-galaxy) lensing can be used to test models of galaxy formation and evolution.
