Mechanism study of an articular cartilage repair material and its forward‐looking test for space medicine

open access: yesBMEMat, EarlyView.
The regeneration process following dLhCG engraftment progressed through four distinct and interconnected stages. dLhCG maintained its regenerative efficacy after 6 months of cosmic exposure, supporting its potential application in space medicine.

On the physical basis of cosmic time [PDF]

open access: yes, 2008
In this manuscript we initiate a systematic examination of the physical basis for the time concept in cosmology. We discuss and defend the idea that the physical basis of the time concept is necessarily related to physical processes which could ...

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

open access: yesChemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Compositional Stages in the Thermal Activation of Metal‐Organic Frameworks in Vacuo: In Situ Spectroscopy and Computation

open access: yesChemistry – A European Journal, EarlyView.
The ultrahigh surface area intrinsic to many metal‐organic frameworks (MOFs) may only be accessed after the removal of synthesis solvent from within the pores. This study elucidates the electronic and structural changes undergone through the guest removal process within a commonly used CUS MOF.

Intravenous Lipopolysaccharide Challenge in Healthy Participants Reveals Pharmacodynamic Markers in Blood and Bone Marrow for Early‐Phase Oncology Drug Development

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Demonstrating pharmacological effects in early‐phase oncology clinical trials remains challenging, largely due to the lack of robust pharmacodynamic markers. Lipopolysaccharide (LPS) is used as an immune challenge agent in healthy participants to study drugs for autoimmune conditions.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Triangulating the height of cosmic noise absorption: A method for estimating the characteristic energy of precipitating electrons [PDF]

open access: yes, 2010
Energetic electrons (tens to hundreds of keV) deposit significant energy into the D layer of the ionosphere. Riometers provide a means of monitoring this electron precipitation by measuring the associated cosmic noise absorption (CNA), but individually ...

Neighborhood Disadvantage and Comorbid Mental Health Conditions in Adolescents and Young Adults With Eating Disorders

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Anxiety and depression are highly prevalent among adolescents and young adults with eating disorders. A comorbid mental health condition is associated with worsened long‐term eating disorder outcomes. While individual risk factors for comorbid anxiety or depression and eating disorders have been elucidated, the impact of external ...
