The Many Routes to AGN Feedback

Frontiers in Astronomy and Space Sciences, 2017
The energy released by Active Galactic Nuclei (AGN) in the form of radiation, winds, or radio plasma jets, is known to impact on the surrounding interstellar medium. The result of these processes, known as AGN (negative) feedback, is suggested to prevent

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Individual Investor Mutual-Fund Flows [PDF]

This paper studies the relation between individuals' mutual fund flows and fund characteristics, establishing three key results. First, consistent with tax motivations, individual investors are reluctant to sell mutual funds that have appreciated in ...

Complex morphology and kinematics at the heart of the very low luminosity object IRAM 04191+1522

Astronomy & Astrophysics
Context. The mechanisms responsible for the formation of the majority of brown dwarfs (BDs) remain a matter of debate. It is unclear whether the majority of BDs form in molecular cloud cores in a process akin to a scaled-down version of low-mass star ...

Hα emission from Mira (omicron Ceti) [PDF]

Serbian Astronomical Journal
Here we report spectral observations of Mira (omicron Ceti). The comparison between the spectra reveals Hα emission during three minima of the Mira cycle (August 2019, January 2024, and January 2025). The emission has equivalent width EW(Hα) ~ 4

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

The origin of dispersion in the wind mass-loss rate–luminosity relation of massive O stars

Astronomy & Astrophysics
Context. Stellar winds of hot stars are accelerated by the radiative force that mainly comes from the line transitions of heavy elements. As a result, the wind mass-loss rate is expected to scale mostly with the stellar luminosity.

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

FEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Outflows from Insured Unemployment in Hungary, 1992-1996 [PDF]

The paper looks at outflows from registered unemployment in Hungary between 1992 and 1996 using microdata from the unemployment insurance system. We address two questions. First, we investigate the trends in outflows in the period.

Quasar Massive Ionized Outflows Traced by CIV λ1549 and [OIII]λλ4959,5007

Frontiers in Astronomy and Space Sciences, 2017
The most luminous quasars (with bolometric luminosities are ≳ 1047 erg/s) show a high prevalence of CIV λ1549 and [OIII]λλ4959,5007 emission line profiles with strong blueshifts.
