Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA
FEBS Open Bio, EarlyView.Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

N-body modeling of globular clusters
, 2016 We have performed a large grid of 900 N-body simulations of star clusters and compared their velocity dispersion and surface density profiles after a Hubble time with observed profiles of Galactic globular clusters in order to derive the masses, M=L ...

The Milky Way Nuclear Star Cluster
, 2011 In the center of the Milky Way, as well as in many other galaxies, a compact star cluster around a very massive black hole is observed. One of the possible explanations for the formation of such Nuclear Star Clusters is based on the "merging" of globular

The Astrophysical JournalGalactic globular clusters consist of two main stellar populations, the pristine (1P) and polluted (2P) stars. The fraction of 1P stars in clusters, F _1P , is a decreasing function of the present-day cluster mass, m _prst . The information about cluster

Star Cluster Evolution: From Young Massive Star Clusters to Old Globulars [PDF]
, 2009 Young, massive star clusters are the most notable and significant end products of violent star-forming episodes triggered by galaxy collisions, mergers, and close encounters. The question remains, however, whether or not at least a fraction of the compact YMCs seen in abundance in extragalactic starbursts, are potentially the progenitors of globular ...

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Globular clusters: a chemical roadmap between anomalies and homogeneity
, 2020 . For several decades, globular clusters have been considered the best example of simple stellar populations, hosting coeval and chemical homogeneous stars.

Spectroscopic Study of Globular and Fuzzy Clusters in Lenticular Galaxy NGC 1023
The Astrophysical JournalWe here report the results from spectroscopic observations of a sample of 26 globular cluster (GC) and 21 faint fuzzy (FF) candidates in the lenticular galaxy NGC 1023 using the 10.4 m Gran Telescopio Canarias.

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.

Ellipticals and Globular Clusters: some common features
, 2003 Globular clusters models with a cut-off in the phase space were extended to elliptical galaxies by Ivan R.King since 1966. Moreover, it was recently proved (e.g., Djorgovski 1995, Burstein et al.
