ESO 546-G34: The most metal poor LSB galaxy? [PDF]

, 2011
We present a re-analysis of spectroscopic data for 23 HII-regions in 12 blue, metal-poor low surface brightness galaxies (LSBGs) taking advantage of recent developments in calibrating strong-line methods. In doing so we have identified a galaxy (ESO 546-G34) which may be the most metal-poor LSB galaxy found in the local Universe.

Colliding filaments in the molecular cloud G34

Astronomy & Astrophysics
The molecular cloud complex G34 is located at a distance of 2.12 ± 0.38 kpc and contains two giant filaments, F1 and F2. It is considered a good example of colliding filaments. We mapped these two filaments using the 13CO and 12CO (J = 1−0) lines that were observed with the 13.7 m millimeter-wavelength telescope of the Purple Mountain Observatory.

ADULT HISTONE G34 MUTANT GLIOMAS - A SINGLE CENTRE EXPERIENCE OVER 10 YEARS [PDF]

Neuro-Oncology, 2023
Abstract AIMS Histone G-34-mutant (H3 G34) gliomas are rare, aggressive infiltrating tumours of the cerebral hemispheres and are classified as WHO grade 4 paediatric type diffuse high-grade glioma. They most commonly affect children and adolescents.

Histone H3.3 G34 Mutations Alter Histone H3K36 and H3K27 Methylation In Cis. [PDF]

Journal of Molecular Biology, 2018
Histone H3 encoding genes, particularly H3F3A and H3F3B, the genes encoding the variant histone H3.3, are mutated at high frequency in pediatric brain and bone malignancies. Compared to the extensive studies on K27M and K36M mutations, little is known about the mechanism of G34 mutations found in pediatric glioblastoma or giant cell tumors of the bone.

A Case of Diffuse Hemispheric Glioma, H3 G34-mutant with PNET-like Glioblastoma Pathology [PDF]

Neuro-Oncology, 2022
Abstract BACKGROUND H3 G34-mutant high-grade gliomas occur primarily in children but can also be encountered in adults. The aim of the present study was to describe the characteristics of H3 G34-mutant high-grade gliomas in adults. MATERIAL AND METHODS

HGG-39. CLINICAL CHARACTERISTICS AND SURVIVAL OUTCOMES OF DIFFUSE HEMISPHERIC GLIOMA, H3 G34-MUTANT: INTERIM RESULTS OF A MULTICENTRE INTERNATIONAL STUDY [PDF]

Neuro Oncol
BACKGROUND Diffuse hemispheric glioma, H3 G34-mutant (G34-DHG) is generally associated with very poor outcome. Little is known, however, regarding long-term survivors and associated prognostic factors.

Cerebral hemispheric glioblastoma with PNET-like morphology and histone H3.3 G34 mutation in younger patients: Report of three rare cases and diagnostic pitfalls

Indian Journal of Pathology and Microbiology, 2020
Recurrent mutations in H3F3A that encodes the histone 3 variant H3.3, lead to amino acid substitutions including K27M and G34R/V-which are observed in high-grade gliomas (HGGs) of children and young adults.
