Hubble Space Telescope Near-Ultraviolet Spectroscopy of the Bright CEMP-no Star BD+44 493

, 2014
We present an elemental-abundance analysis, in the near-ultraviolet (NUV) spectral range, for the extremely metal-poor star BD+44 493, a 9th magnitude sub-giant with [Fe/H] = -3.8 and enhanced carbon, based on data acquired with the Space Telescope ...

Prophylactic Management of Vestibular Migraine: A Systematic Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Vestibular migraine (VM) is a neurological disorder characterized by episodic vertigo in patients with migraine, contributing to substantial functional impairment. Although VM is relatively common, a consensus on effective prophylactic treatments is lacking.

Re‐thinking Strategies for a Pharmaceutical Approach to Pain‐related to Connective Tissue Related Raynaud's Phenomenon in the United States

Arthritis Care &Research, Accepted Article.
Introduction There are no Food and Drug Administration (FDA) approved therapies for Raynaud's phenomenon (RP) treatment in the United States (U.S.). Clinical trials have been challenged by study design. Important advances in RP patient reported outcome measures and mechanistic quantification allows RP‐related pain characterization.

The origin of the Crab Nebula and the electron capture supernova in 8-10 M solar mass stars [PDF]

The chemical composition of the Crab Nebula is compared with several presupernova models. The small carbon and oxygen abundances in the helium-rich nebula are consistent with only the presupernova model of the star whose main sequence mass was MMS ...

Osteogenic Effects of Ion Released from Biodegradable Metallic Magnesium and Calcium Coating

Advanced Biology, EarlyView.
This study explores how magnesium–calcium coatings on titanium promote osteogenesis by releasing ions and elevating pH during degradation. Using osteoblast‐like cells, the research demonstrates that both ion release and pH changes contribute to cell proliferation, differentiation, and mineralization, offering new insights into the design of bioactive ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
