Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain

Developmental Dynamics, EarlyView.
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

The development of the red giant branch. II - Astrophysical properties

The Astrophysical Journal, 1990
Evolutionary sequences developed in another paper are used here to investigate the properties of the red giant branch (RGB) phase transition. Results are found for compositions in the range Y(MS) between 0.20 and 0.30 and Z between 0.004 and 0.04. The transition mass M(HeF) increases as either Y(MS) decreases or Z increases.

Seizures and electroencephalographic findings in inborn errors of metabolism: Clues to differential diagnosis in the neonatal period, infancy, childhood and adolescence, and review of the literature

Epileptic Disorders, EarlyView.
Abstract Although inborn errors of metabolism (IEM) are a rare cause of epilepsy, seizures are a common presentation in these disorders. Seizures in IEM are frequently refractory to conventional anti‐seizure medication and might warrant initiation of specific treatments based on vitamins or dietary modifications or provision of alternative substrates ...

Discovery of a Metal-poor Red Giant Star with the Highest Ultralithium Enhancement

The Astrophysical Journal
We present the discovery of 2MASS J05241392−0336543 (hereafter J0524−0336), a very metal-poor ([Fe/H] = −2.43 ± 0.16), highly r -process-enhanced ([Eu/Fe] = +1.34 ± 0.10) Milky Way halo field red giant star, with an ultrahigh Li abundance of A (Li, 3D ...

Non-radial oscillations in M-giant semi-regular variables: Stellar models and Kepler observations

, 2014
The success of asteroseismology relies heavily on our ability to identify the frequency patterns of stellar oscillation modes. For stars like the Sun this is relatively easy because the mode frequencies follow a regular pattern described by a well ...

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Clinical periodontal diagnosis

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Washington Photometry of the Red Giant Branch in NGC 6388

The Astronomical Journal, 2007
We present Washington photometry of the giant branches of the relatively metal-rich globular cluster NGC 6388 and compare it with 47 Tuc. By examining the spatial distribution of stellar colors across the red giant branch and using spectroscopic data on several bright giants, we found that NGC 6388's center is affected by differential reddening of at ...

Light-Element Abundance Variations at Low Metallicity: the Globular Cluster NGC 5466

, 2010
We present low-resolution (R~850) spectra for 67 asymptotic giant branch (AGB), horizontal branch and red giant branch (RGB) stars in the low-metallicity globular cluster NGC 5466, taken with the VIRUS-P integral-field spectrograph at the 2.7-m Harlan J.

HiFi based metagenomic assembly strategy provides accuracy near isolated genome resolution in MAG assembly

iMetaOmics, EarlyView.
Recovering high‐contiguity, circular bacterial genomes from complex microbiomes (e.g., gut) is challenged by limitations of short‐read and error‐prone long‐read sequencing. This study comprehensively compares PacBio High‐Fidelity (HiFi) sequencing‐based metagenome‐assembled genomes (MAGs) against Illumina MAGs, Oxford Nanopore Technologies (ONT) MAGs ...
