A Novel NR3C1 Frameshift Variant Associated With Familial Glucocorticoid Resistance Syndrome: An Integrated Analysis of Steroid Profiling and Structural Modeling

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Glucocorticoid resistance syndrome (GRS) is a rare hereditary disorder caused by pathogenic variants in NR3C1, characterized by marked phenotypic heterogeneity and frequent misdiagnosis as primary aldosteronism or subclinical Cushing's syndrome.

Heterozygous Variants in LRP1 Cause a Neurodevelopmental Disorder With Congenital Heart Defects

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT LRP1 encodes the low‐density lipoprotein (LDL) receptor‐related protein 1 (LRP1), a transmembrane protein involved in endocytosis and activation of multiple signaling pathways. LRP1 variants have been implicated in the pathogenesis of congenital heart defects (CHD), Alzheimer's disease, and neurodevelopmental disorders (NDD).

Coronae of cool stars

Astrophysics and Space Science, 1971
With the hypothesis generally adopted as responsible for the heating of the solar corona an attempt was made to predict the coronal temperature for a few cool stars. Stars with effective temperatures between 2500K and 3700K, with logg-values of 3 or 4, appear to have coronal temperatures only 600 to 25000K higher thanT eff.

The Corona of the Sun as a Star

AIP Conference Proceedings, 2006
We study the physics of the solar corona as a whole, i.e. of the Sun as a Star, in order to understand its global features and to provide a template for stellar coronae. In this process we strive to understand the features of various structures which compose the solar corona.

The R Coronae Borealis Stars

Publications of the Astronomical Society of the Pacific, 1996
This year marks the bicentennial of the discovery of the variability of R Coronae Borealis. The R Coronae Borealis (RCB) stars are distinguished from other hydrogen-deficient objects by their spectacular dust formation episodes. They may decline by up to 8 magnitudes in a few weeks revealing a rich emission-line spectrum. Their atmospheres have unusual

Occultation of a Radio Star by the Solar Corona

Nature, 1952
IT has been suggested1 that the radiation from a radio star might be cut off by refraction in the solar corona, even when the angular separation of the sun and the star is several times the angular radius of the visible disk (R⊙). The existing data on the coronal electron density have been used for predicting the effective radius of the sun for ...

On the coronae of rapidly rotating star. V - The other stars

Publications of the Astronomical Society of the Pacific, 1985
Results of Einstein X-ray observations of 25 stellar systems are presented. The systems observed include 15 spectroscopic binaries of which eleven were detected; nine were serendipitous detections, three of which may be new RS CVn systems. Coronal activity levels and their implications for these stars are discussed.

Periodicities in the green corona for the sun as a star

Solar Physics, 1990
A coronal index (CI) derived from the limb observations of the 530.3 nm emission corona (green corona) over 1964–1987 was analyzed by the Fourier transform technique (FTT) to find periodicity in this layer of solar atmosphere. As expected, two pronounced periods were indicated: the rotational, about 27 d, and the activity cycle length, 11 years. Beside

A model for the corona of a spherical star cluster

Vestnik St. Petersburg University: Mathematics, 2008
A general model for the outer layers of steady spherical star systems is considered. The corona is assumed to be formed by stars flying out of the system along ballistic orbits. Expressions for density runs and velocity dispersions are found. Models of three kinds are studied, namely, systems with isotropic velocity distribution, spheres with purely ...
