Nanoparticles Surface Chemistry Influence on Protein Corona Composition and Inflammatory Responses

open access: yesNanomaterials, 2022
Nanoparticles are widely used for biomedical applications such as vaccine, drug delivery, diagnostics, and therapeutics. This study aims to reveal the influence of nanoparticle surface functionalization on protein corona formation from blood serum and ...

The Structure and Spectral Features of a Thin Disk and Evaporation-Fed Corona in High-Luminosity AGNs

open access: yes, 2012
We investigate the accretion process in high-luminosity AGNs (HLAGNs) in the scenario of the disk evaporation model. Based on this model, the thin disk can extend down to the innermost stable circular orbit (ISCO) at accretion rates higher than $0.02\dot{

Stellar coronae [PDF]

open access: yesSymposium - International Astronomical Union, 1997
The last two decades have seen the emergence of a new field in stellar astrophysics, the study of stellar coronae mostly in X-ray domain. With the advent of soft X-ray imagery X-ray emission was found from many thousands of solar-like stars. I will summarize the most important findings of X-ray surveys of late type stars and put the results in the ...

Kebijakan Pemberlakuan Lock Down Sebagai Antisipasi Penyebaran Corona Virus Covid-19

open access: yesSALAM: Jurnal Sosial dan Budaya Syar-i, 2020
2020 is a worrying year for all countries, including Indonesia. This is due to the emergence of the Corona virus outbreak, which originated in Wuhan City of China, and spread throughout the world.

Chromospheric Anemone Jets as Evidence of Ubiquitous Reconnection

open access: yes, 2008
The heating of the solar chromosphere and corona is a long-standing puzzle in solar physics. Hinode observations show the ubiquitous presence of chromospheric anemone jets outside sunspots in active regions.

The in vitro gastrointestinal digestion-associated protein corona of polystyrene nano- and microplastics increases their uptake by human THP-1-derived macrophages

open access: yesParticle and Fibre Toxicology
Micro- and nanoplastics (MNPs) represent one of the most widespread environmental pollutants of the twenty-first century to which all humans are orally exposed.

Measurements of heterogeneity in proteomics analysis of the nanoparticle protein corona across core facilities

open access: yesNature Communications, 2022
Robust characterization of the protein corona—the layer of proteins that spontaneously forms on the surface of nanoparticles immersed in biological fluids—is vital for prediction of the safety, biodistribution, and diagnostic/therapeutic efficacy of ...

Protein Corona of Nanoparticles: Isolation and Analysis

open access: yesChem & bio engineering
Nanoparticles entering biological systems or fluids inevitably adsorb biomolecules, such as protein, on their surfaces, forming a protein corona. Ensuing, the protein corona endows nanoparticles with a new biological identity and impacts the interaction ...
