Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

SDSS J0018-0939: A Clear Signature of Sub-Chandrasekhar Mass Type 1a Supernova
The Astrophysical JournalVery metal-poor (VMP) stars ([Fe/H] ≤ −2) that have subsolar values of [X/Fe] for α elements such as Mg, Si, and Ca, are referred to as α -poor VMP stars.

Suppression of accretion onto low-mass Population III stars
, 2010 Motivated by recent theoretical work suggesting that a substantial fraction of Population (Pop) III stars may have had masses low enough for them to survive to the present day, we consider the role that the accretion of metal-enriched gas may have had in

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Astronomy & AstrophysicsCosmological simulations find that pockets of star-forming gas could remain pristine up until the epoch of reionization (EoR) due to the inhomogeneous nature of metal mixing and enrichment in the early Universe.

Population III and the Near-Infrared Background Excess
, 2005 We make a critical assessment of models that attribute the recently detected near-infrared background ``excess'' (NIRBE) to the redshifted light from Population III objects.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

The Astrophysical JournalThe most metal-poor stars record the earliest metal enrichment triggered by Population III stars. By comparing observed abundance patterns with theoretical yields of metal-free stars, physical properties of their first star progenitors can be inferred ...

Chemical Yields from the First Stars
, 1999 We examine the dependence of stellar yields on the metallicity Z of the stellar population. This effect may be important for the very first chemical enrichment from Population III stars, at very low Z.

Where are the population III stars
The Astrophysical Journal, 1982 There appears to be no observational evidence for the existence of true Population III stars (zero-metal abundance, first generation stars) in our Galaxy. They may only be found in an earlier generation of galaxies which formed in the denser regions of space, such as the Virgo cluster.
