The need for improved methodology in protein corona analysis

Nature Communications, 2022
The protein corona is a key component controlling biological activity, that develops on foreign materials when introduced to biological environments. This comment discusses the risk of errors from poor methodology that can lead to misinterpretation and ...

Relating magnetic reconnection to coronal heating

, 2015
It is clear that the solar corona is being heated and that coronal magnetic fields undergo reconnection all the time. Here we attempt to show that these two facts are in fact related - i.e. coronal reconnection generates heat.

Hard and Soft Protein Corona of Nanomaterials: Analysis and Relevance

Nanomaterials, 2021
Upon contact with a biological milieu, nanomaterials tend to interact with biomolecules present in the media, especially proteins, leading to the formation of the so-called “protein corona”. As a result of these nanomaterial–protein interactions, the bio-

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

Energetics of a black hole: constraints on the jet velocity and the nature of the X-ray emitting region in Cyg X-1

, 2009
We investigate the energetics of the jet and X-ray corona of Cyg X-1. We show that the current estimates of the jet power obtained from Halpha and [O III] measurements of the optical nebula surrounding the X-ray source allow one to constrain the bulk ...

Corona-Zeiten, Corona-Räume

, 2020
En réaction à la propagation de la pandémie de Covid-19, beaucoup de personnes à travers le monde étaient confrontés à une rupture des routines sociales et spatiales. En Allemagne, les gouvernements régionaux ont joué un rôle essentiel afin de freiner la propagation du virus. Dans ce contexte, la façon dans laquelle des lois et des règles pénètrent les

Hematopoietic (stem) cells—The elixir of life?

FEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Thin accretion disc with a corona in a central magnetic field

, 2008
We study the steady-state structure of an accretion disc with a corona surrounding a central, rotating, magnetized star. We assume that the magneto-rotational instability is the dominant mechanism of angular momentum transport inside the disc and is ...

Galactic fountains and the rotation of disc-galaxy coronae [PDF]

, 2011
In galaxies like the Milky Way, cold (~ 10^4 K) gas ejected from the disc by stellar activity (the so-called galactic-fountain gas) is expected to interact with the virial-temperature (~ 10^6 K) gas of the corona.
