The Milky Way bulge

open access: yes
This chapter reviews the three-dimensional structure, age, kinematics, and chemistry of the Milky Way (MW) region within ~2 kpc from its center (hereafter referred to as the 'bulge') from an observational perspective. While not exhaustive in citations, this review provides historical context and discusses the main controversies and limitations in the ...

ROS‐Scavenging Multifunctional Microneedle Patch Facilitating Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
A reactive oxygen species (ROS) scavenging and immunomodulatory microneedle patch based on hyaluronic acid methacrylate (HaMA) and Flightless I (Flii)‐siRNA‐laden arginine functionalized poly (β‐amino ester)/alginate particles is developed for chronic wound healing applications.

Accurate, Precise, and Physically Self-consistent Ages and Metallicities for 400,000 Solar Neighborhood Subgiant Branch Stars

open access: yesThe Astrophysical Journal
Age is the most difficult fundamental stellar parameter to infer for isolated stars. While isochrone-based ages are in general imprecise for both main-sequence dwarfs and red giants, precise isochrone-based ages can be obtained for stars on the subgiant ...

Silencing Myostatin Using In Vivo Self‐Assembled siRNA Protects Against Cancer‐ and Dexamethasone‐Induced Muscle Atrophy

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reports an in vivo self‐assembled siRNA strategy that enables the liver to generate small extracellular vesicles (sEVs) tagged with a muscle‐targeting peptide (MSP) and naturally loaded with myostatin (MSTN)‐siRNA. These MSP‐tagged sEVs are systemically delivered to skeletal muscle, efficiently silence MSTN, promote muscle hypertrophy, and ...

A Consistent Explanation for the Unusual Initial Mass Function and Star Formation Rate in the Central Molecular Zone (CMZ)

open access: yesThe Astrophysical Journal
We examine various physical processes that may explain the shallow high-mass slope of the initial mass function (IMF), as well as the low star formation rate (SFR) in star-forming molecular clouds (MCs) in the Central Molecular Zone (CMZ).

Integrin β4‐Enriched Small Extracellular Vesicle as Drug Delivery Vehicle for Targeting Pulmonary Metastasis of Hepatocellular Carcinoma

open access: yesAdvanced Healthcare Materials, EarlyView.
The expression of integrin β4 (ITGβ4) on small extracellular vesicle (sEV) correlates with lung‐tropism. Enrichment of ITGβ4 on sEVs enhances their lung‐targeting ability. The sEVs loaded with doxorubicin exhibit superior therapeutic efficacy in a lung metastasis mouse model.
