Study of globular cluster M53: new variables, distance, metallicity [PDF]

Astronomy and Astrophysics, 2009
We study the variable star content of the globular cluster M53 to compute the physical parameters of the constituting stars and the distance of the cluster.

Unraveling the multifaceted resilience of arsenic resistant bacterium Deinococcus indicus [PDF]

Frontiers in Microbiology, 2023
Arsenic (As) is a toxic heavy metal widely found in the environment that severely undermines the integrity of water resources. Bioremediation of toxic compounds is an appellative sustainable technology with a balanced cost-effective setup.

CN Bimodality at Low Metallicity: The Globular Cluster M53 [PDF]

Publications of the Astronomical Society of the Pacific, 2007
We present low resolution UV-blue spectroscopic observations of red giant stars in the globular cluster M53 ([Fe/H]=-1.84), obtained to study primordial abundance variations and deep mixing via the CN and CH absorption bands. The metallicity of M53 makes

The Blue Straggler population in the globular cluster M53 (NGC5024): a combined HST, LBT, CFHT study

, 2008
We used a proper combination of multiband high-resolution and wide field multi-wavelength observations collected at three different telescopes (HST, LBT and CFHT) to probe Blue Straggler Star (BSS) populations in the globular cluster M53.

The unusually large population of Blazhko variables in the globular cluster NGC 5024 (M53) [PDF]

Monthly Notices of the Royal Astronomical Society, 2011
We report the discovery of amplitude and phase modulations typical of the Blazhko effect in 22 RRc and 9 RRab type RR Lyrae stars in NGC 5024 (M53). This brings the confirmed Blazhko variables in this cluster to 23 RRc and 11 RRab, that represent 66% and

Discovery of New RR Lyrae Stars in the Center of the Globular Cluster M53 [PDF]

Journal of Astronomy and Space Sciences, 1999
We report the discovery of 17 new RR Lyrae variables in the central region (r≤1’) of the globular cluster M53. There candidates were identified by using the Welch & Stetson (1993) technique and confirmed by checking individual light curves in both B and ...

Group A Streptococcus interacts with glycosaminoglycans via M proteins to modulate bacterial adherence in vitro. [PDF]

FEBS J
Interactions between bacteria and the extracellular matrix are a prerequisite for colonisation and infection. Phylogenetically diverse M proteins of group A Streptococcus (GAS) can selectively bind sulfated glycosaminoglycans with high affinity. M protein‐mediated recruitment of chondroitin sulfate and dermatan sulfate was shown to increase GAS ...

Fibrinogen-binding M-related proteins facilitate the recruitment of plasminogen by Streptococcus pyogenes. [PDF]

Protein Sci
Abstract Group A Streptococcus (GAS) M‐related proteins (Mrp) are dimeric α‐helical coiled‐coil cell‐wall‐attached proteins. During infection, Mrp recruit human fibrinogen (Fg) to the bacterial surface, enhancing phagocytosis resistance and promoting growth in human blood.
