The long-period companions of multiple stars tend to have moderate eccentricities

open access: yes, 2001
We examined the statistics of an angle between the radius vector of a visual companion of a mul- tiple star and the vector of its apparent relative motion in the system.

Models for the lithium abundances of multiple populations in globular clusters and the possible role of the Big Bang lithium

open access: yes, 2012
Globular cluster stars show chemical abundance patterns typical of hot-CNO processing. Lithium is easily destroyed by proton capture in stellar environments, so its abundance may be crucial to discriminate among different models proposed to account for ...

Circulating histones as clinical biomarkers in critically ill conditions

open access: yesFEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

Multiplicity of stars with planets

open access: yes
We aimed to assess how stellar multiplicity affects exoplanets’ presence and properties. We analysed all exoplanet host stars within 100 pc using Gaia DR3 data, advanced statistical methods, and additional information from the Washington Double Star catalogue and literature.

Low-mass Stellar and Substellar Candidate Companions around Massive Stars in Sco OB1 and M17

open access: yesThe Astronomical Journal
Massive stars are recognized for their high degree of multiplicity, yet the mass ratio regime below 0.1 remains insufficiently explored. It is therefore unknown whether extremely low-mass (possibly substellar) companions can form and survive in the ...

The properties of close multiple stars

open access: yes, 1981
A reexamination of the properties of close multiple systems is conducted, taking into account recent numerical, analytical, and observational results. The orbital elements of 43 spectroscopic multiple systems are presented in a table.

Bright 22 $\mu$m Excess Candidates from WISE All-Sky Catalog and Hipparcos Main Catalog

open access: yes, 2013
In this paper we present a catalog which includes 141 bright candidates ($\leq10.27$ mag, V band) showing the infrared (IR) excess at 22 $\mu$m. Of which, 38 stars are known IR excess stars or disk, 23 stars are double or multiple stars and 4 are Be ...

Insights into pegRNA design from editing of the cardiomyopathy‐associated phospholamban R14del mutation

open access: yesFEBS Letters, EarlyView.
This study reveals how prime editing guide RNA (pegRNA) secondary structure and reverse transcriptase template length affect prime editing efficiency in correcting the phospholamban R14del cardiomyopathy‐associated mutation. Insights support the design of structurally optimized enhanced pegRNAs for precise gene therapy.

Intron‐oriented HTLV‐1 integration in an adult T‐cell leukemia/lymphoma cell line sustains expression of intact ift81 mRNA

open access: yesFEBS Letters, EarlyView.
In the adult T‐cell leukemia/lymphoma (ATL) cell line ED, the human T‐cell leukemia virus type 1 (HTLV‐1) provirus was integrated into the intron of the ift81 gene in the antisense orientation. Despite this integration, both the intact ift81 and the viral oncogene hbz were simultaneously expressed, likely due to the functional insufficiency of viral ...
