Emerging SARS-CoV-2 Variants of Concern (VOCs): An Impending Global Crisis

Biomedicines, 2021
The worldwide battle against the SARS-CoV-2 virus rages on, with millions infected and many innocent lives lost. The causative organism, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a beta coronavirus that belongs to the Coronaviridae

Transplantation of progenitor cells and regeneration enhancement in acute myocardial infarction - (TOPCARE-AMI) [PDF]

, 2002
Background - Experimental studies suggest that transplantation of blood-derived or bone marrow–derived progenitor cells beneficially affects postinfarction remodeling.

CD8+ T Lymphocyte Self-Renewal during Effector Cell Determination

Cell Reports, 2016
Selected CD8+ T cells must divide, produce differentiated effector cells, and self-renew, often repeatedly. We now show that silencing expression of the transcription factor TCF1 marks loss of self-renewal by determined effector cells and that this ...

iPTF13bvn: The First Evidence of a Binary Progenitor for a Type Ib Supernova [PDF]

, 2014
The recent detection in archival HST images of an object at the the location of supernova (SN) iPTF13bvn may represent the first direct evidence of the progenitor of a Type Ib SN.

The Type IIn Supernova SN 2010bt: The Explosion of a Star in Outburst [PDF]

, 2018
Indexación: Scopus.It is well known that massive stars (M > 8 M ) evolve up to the collapse of the stellar core, resulting in most cases in a supernova (SN) explosion.

Stem/progenitor cells in the developing human lung

Journal of Pediatric and Neonatal Individualized Medicine, 2016
Human lungs are composed of more than 40 cell types. The lung is classified as a “conditionally renewing” tissue and is able of a quick response to cellular damage thanks to the presence of multiple stem/progenitor cells.

Gap Transients Interacting with Circumstellar Medium

Universe, 2022
In the last 20 years, modern wide-field surveys discovered a new class of peculiar transients, which lie in the luminosity gap between standard supernovae and classical novae. These transients are often called “intermediate luminosity optical transients”

SVCT2 Vitamin C Transporter Expression in Progenitor Cells of the Postnatal Neurogenic Niche

Frontiers in Cellular Neuroscience, 2013
Known as a critical antioxidant, recent studies suggest that vitamin C plays an important role in stem cell generation, proliferation and differentiation. Vitamin C also enhances neural differentiation during cerebral development, a function that has not

EVLA Observations Constrain the Environment and Progenitor System of Type Ia Supernova 2011fe

, 2012
We report unique EVLA observations of SN 2011fe representing the most sensitive radio study of a Type Ia supernova to date. Our data place direct constraints on the density of the surrounding medium at radii ~10^15-10^16 cm, implying an upper limit on ...
