Engineering Gypsophila elegans hairy root cultures to produce endosomal escape‐enhancing saponins
Plant Biotechnology Journal, EarlyView.Summary The limited cytosolic delivery of DNA and protein‐based therapeutics due to endosomal entrapment reduces drug efficacy, increasing treatment costs and possible side effects in human and veterinary medicine as a consequence of higher administered dosages.

Active Galactic Nuclei in polarized light
Open Astronomy, 2019 Due to the compactness active galactic nuclei (AGN) are still unresolved with optical observations. However, structure and physical conditions of the matter in their central parts are especially important to study the processes of the matter accretion to

Accretion Flows in X--Ray Binaries and Active Galactic Nuclei [PDF]
arXiv, 2001 Hard X-ray emission is ubiquitous in accreting black holes, both in Galactic binary systems and in Active Galactic Nuclei. I review the different spectra which can be seen from these systems, and possible ways of producing this emission. X-ray reflection should give an observational test of these scenarios, but we need better models before this can ...

LINERs as Low-Luminosity Active Galactic Nuclei [PDF]
, 1998 Many nearby galaxies contain optical signatures of nuclear activity in the form of LINER nuclei. LINERs may be the weakest and most common manifestation of the quasar phenomenon. The physical origin of this class of objects, however, has been ambiguous.

A Role for the Plastidial GPT2 Translocator in the Modulation of Lignin Biosynthesis
Plant, Cell &Environment, EarlyView.ABSTRACT Engineering plants with reduced lignin content can result in pleiotropic growth defects. In stems of Arabidopsis plants with reduced expression of hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT), the plastidial glucose 6‐phosphate: phosphate co‐transporter GPT2 is highly overexpressed, and this coincides with reduced lignin ...

On the Properties of X-Ray Corona in Seyfert 1 Galaxies
The Astrophysical JournalWe carried out a uniform and systematic analysis of a sample of 112 nearby bright Seyfert 1 type active galactic nuclei, the observations of which were carried out by the Nuclear Spectroscopic Telescope Array between 2013 August and 2022 May.

Veterinary Clinical Pathology, EarlyView.Abstract MicroRNAs (miRNAs or miRs) are small, non‐coding RNAs that play a crucial role in gene regulation, making them potential biomarkers for various diseases. In the field of veterinary medicine, there is a growing interest in exploring the diagnostic and therapeutic potential of miRNAs in kidney diseases affecting dogs and cats.

Test for Echo: X-Ray Reflection Variability in the Seyfert-2 Active Galactic Nucleus NGC 4388
The Astrophysical JournalWe report on a study of the narrow Fe K α line and reflection spectrum in the well-known Seyfert-2 active galactic nucleus (AGN), NGC 4388. X-ray spectra summed from two extensive NICER monitoring campaigns, separated by years, show strong evidence of ...
