HSP70 governs permeability and mechanotransduction in primary human endothelial cells

open access: yesFEBS Open Bio, EarlyView.
HSP70 chemical inhibition reduces endothelial cell proliferation and increases permeability, the latter supported by normal interendothelial junctional protein distribution. HSP70 also plays a role in shear stress response, a hemodynamic force naturally present in blood vessels and correlated with vessel protection.

Apparent age spreads in clusters and the role of stellar rotation [PDF]

open access: yes, 2015
We use the Geneva Syclist isochrone models that include the effects of stellar rotation to investigate the role that rotation has on the resulting colour-magnitude diagram (CMD) of young and intermediate age clusters.

Stellar Rotation in Young Clusters. II. Evolution of Stellar Rotation and Surface Helium Abundance [PDF]

open access: yesThe Astrophysical Journal, 2006
We derive the effective temperatures and gravities of 461 OB stars in 19 young clusters by fitting the H-gamma profile in their spectra. We use synthetic model profiles for rotating stars to develop a method to estimate the polar gravity for these stars, which we argue is a useful indicator of their evolutionary status.

Homologous expression and purification of human HAX‐1 for structural studies

open access: yesFEBS Open Bio, EarlyView.
This research protocol provides detailed instructions for cloning, expressing, and purifying large quantities of the intrinsically disordered human HAX‐1 protein, N‐terminally fused to a cleavable superfolder GFP, from mammalian cells. HAX‐1 is predicted to undergo posttranslational modifications and to interact with membranes, various cellular ...

Refining the Stellar Parameters of τ Ceti: a Pole-on Solar Analog

open access: yesThe Astronomical Journal, 2023
To accurately characterize the planets a star may be hosting, stellar parameters must first be well determined. τ Ceti is a nearby solar analog and often a target for exoplanet searches.

PHOTOMETRIC AMPLITUDE DISTRIBUTION OF STELLAR ROTATION OF KOIs—INDICATION FOR SPIN–ORBIT ALIGNMENT OF COOL STARS AND HIGH OBLIQUITY FOR HOT STARS [PDF]

open access: yes, 2015
The observed amplitude of the rotational photometric modulation of a star with spots should depend on the inclination of its rotational axis relative to our line of sight. Therefore, the distribution of observed rotational amplitudes of a large sample of

Altered Dynamic Functional Network Connectivity in Post‐Stroke Aphasia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Previous studies examining post‐stroke aphasia (PSA) patients via resting‐state functional magnetic resonance imaging (rs‐fMRI) have predominantly focused on static functional connectivity. In contrast, the current investigation aims to elucidate the alterations in dynamic functional network connectivity (dFNC) among PSA patients ...

Accurate and Robust Stellar Rotation Periods Catalog for 82771 Kepler Stars Using Deep Learning

open access: yesThe Astronomical Journal
We propose a new framework to predict stellar properties from light curves. We analyze the light-curve data from the Kepler space mission and develop a novel tool for deriving the stellar rotation periods for main-sequence stars.

THE EVOLUTION OF STELLAR ROTATION AND THE HYDROGEN ATMOSPHERES OF HABITABLE-ZONE TERRESTRIAL PLANETS [PDF]

open access: yes, 2015
Terrestrial planets formed within gaseous protoplanetary disks can accumulate significant hydrogen envelopes. The evolution of such an atmosphere due to XUV driven evaporation depends on the activity evolution of the host star, which itself depends ...
