A Catalogue of carbon stars in the LMC [PDF]

Astronomy & Astrophysics, 2001
A catalogue of 7760 carbon stars in the Large Magellenic Cloud is presented. The stars were identified during a systematic survey of objective-prism plates taken with the UK 1.2 m Schmidt Telescope. The catalogue is compared with other lists of carbon stars and the distribution of the carbon stars is discussed.

Mycobacterium tuberculosis sulfurtransferase SseA is activated by its neighboring gene product Rv3284

FEBS Letters, EarlyView.
Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

Chemical Links between a Young M-type T Tauri Star and Its Substellar Companion: Spectral Analysis and C/O Measurement of DH Tau A

The Astrophysical Journal
The chemical abundance measurements of host stars and their substellar companions provide a powerful tool to trace the formation mechanism of the planetary systems.

Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation

FEBS Letters, EarlyView.
The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.

LX Cygni: A carbon star is born [PDF]

Astronomy & Astrophysics, 2016
Context: The Mira variable LX Cyg showed a dramatic increase of its pulsation period in the recent decades and appears to undergo an important transition in its evolution. Aims: We aim at investigating the spectral type evolution of this star over the recent decades as well as during one pulsation cycle in more detail and discuss it in connection with ...

The cytochrome oxidase defect in ISC‐depleted yeast is caused by impaired iron–sulfur cluster maturation of the mitoribosome assembly factor Rsm22

FEBS Letters, EarlyView.
The yeast mitoribosome assembly factor Rsm22 contains a [4Fe‐4S] cluster that is matured by the mitochondrial iron–sulfur cluster assembly (ISC) machinery. Defects in ISC components result in impaired mitochondrial protein synthesis due to a mitoribosome assembly defect.

Discovery of interstellar anions in Cepheus star-forming region [PDF]

, 2011
We report the detection of microwave emission lines from the hydrocarbon anion C6H- and its parent neutral C6H in the star-forming region L1251A (in Cepheus), and the pre-stellar core L1512 (in Auriga).
