Location, Location, Location: Monazite Behaviour During UHT Metamorphism and Melt Crystallization

Journal of Metamorphic Geology, Volume 44, Issue 2, Page 158-175, February 2026.
ABSTRACT Monazite is a robust mineral for recording the suprasolidus evolution of migmatites and granulites. However, monazite commonly has diverse compositions and yields variable dates in a single sample; understanding the controls on monazite behaviour and composition during partial melting and melt crystallization are not always straightforward ...

Genome‐wide screening of potential RNase Y‐processed mRNAs in the M49 serotype Streptococcus pyogenes NZ131

MicrobiologyOpen, 2019
RNase Y is a major endoribonuclease in Group A streptococcus (GAS) and other Gram‐positive bacteria. Our previous study showed that RNase Y was involved in mRNA degradation and processing in GAS.

Dynamics of Stars and Globular Clusters in Galaxy Halos

, 2003
We have obtained kinematical data in the halos of the giant ellipticals M49 and M87. These include globular cluster velocities in M49 to 10 R_eff and planetary nebula velocities in M49 and M87 to 4 R_eff.

Deletion of the L-Lactate Dehydrogenase Gene ldh in Streptococcus pyogenes Leads to a Loss of SpeB Activity and a Hypovirulent Phenotype

Frontiers in Microbiology, 2017
Streptococcus pyogenes uses lactic acid fermentation for the generation of ATP. Here, we analyzed the impact of a deletion of the L-lactate dehydrogenase gene ldh on the virulence of S. pyogenes M49. While the ldh deletion does not cause a general growth

The 5'-nucleotidase S5nA is dispensable for evasion of phagocytosis and biofilm formation in Streptococcus pyogenes.

PLoS ONE, 2019
5'-nucleotidases are widespread among all domains of life. The enzymes hydrolyze phosphate residues from nucleotides and nucleotide derivatives. In some pathobiontic bacteria, 5'-nucleotidases contribute to immune evasion by dephosphorylating adenosine ...

An occurrence of the bacteriophage genes among Streptococcus pyogenes strains of M49 serotype

Medical academic journal, 2011
In this study an occurrence of bacteriophage genes among S. pyogenes strains of M49 serotype was studied by two methods, PCR and DNA-DNA hybridization. It was found, that the presence of the phage genes and/or prophages was associated with geographic region of the strain isolation. Potential correlation between the presence of the phage integrase genes
