Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

TESS Stellar Rotation up to 80 Days in the Southern Continuous Viewing Zone

The Astrophysical Journal
The Transiting Exoplanet Survey Satellite (TESS) mission delivers time-series photometry for millions of stars across the sky, offering a probe into stellar astrophysics, including rotation, on a population scale. However, light-curve systematics related

The red giant branch bump in rotating low-mass stars: Implication for the theory of stellar evolution

Astronomy & Astrophysics
Context. The red giant branch bump (RGB bump) is a key diagnostic of an internal stellar structure, yet the impact of stellar rotation– which is a fundamental parameter altering chemical stratification–on its luminosity, amplitude, and morphology remains

Epilepsy‐Associated Variants of a Single SCN1A Codon Exhibit Divergent Functional Properties

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Pathogenic variants in SCN1A, which encodes the voltage‐gated sodium channel NaV1.1, are associated with multiple epilepsy syndromes exhibiting a range of clinical severity. SCN1A variants are reported in different syndromes, including Dravet syndrome, which is associated with loss‐of‐function, whereas neonatal/infantile‐onset ...

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

Anchoring Stellar Age Indicators: A Cross Calibration of [C/N] and Gyrochronology Ages via the Age–Velocity Dispersion Relation

The Astronomical Journal
Determining stellar ages is challenging, as it depends on other stellar parameters in a nonlinear way and often relies on stellar evolution models to infer the underlying relation between these parameters and age. This complexity increases when comparing

Digital Cognitive Phenotyping for Differential Diagnosis and Monitoring in Neurological Conditions

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To assess the utility, accessibility, and equivalence to supervised scales of online cognitive assessment in older individuals with cognitive impairment. Methods Patients with Alzheimer's disease (AD, n = 31), idiopathic normal pressure hydrocephalus (iNPH, n = 26), and traumatic brain injury (TBI, n = 23) completed online cognitive ...

Stem Cell Transplantation in Friedreich Ataxia: Cure for Leukemia but No Effect on Neurological Progression

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Friedreich Ataxia (FRDA) is a neurodegenerative disorder of children and young adults associated with cardiomyopathy and other systemic complications. We report a 10‐year‐old girl who presented simultaneously with Acute Myelogenous Leukemia and FRDA who was successfully treated for her leukemia with allogeneic hematopoietic stem cell ...

Impact of stellar spots on the high-resolution transmission spectra of a giant planet around a Sun-like star

Astronomy & Astrophysics
Context. Transmission spectroscopy has enabled the analysis of exoplanet atmospheres. However, a major challenge in this field is the “noise” from host stars, caused by stellar activity such as dark spots and bright plages.
