The influence of regional stress and structural control on the shape of maar craters
Volcanica, 2021 Maars are volcanic craters excavated by the interaction of magma and groundwater in subsurface phreatomagmatic explosions. Maar craters display a variety of shapes and sizes, but commonly display elongation.

P-TEFb: The master regulator of transcription elongation
Molecules and Cells, 2022 The positive transcription elongation factor b (P-TEFb) is composed of cyclins T1 or T2 and cyclin dependent kinase 9 that regulate the elongation phase of transcription by RNA polymerase II.

"Quick evaluation method of ozone aging resistance for natural rubber vulcanizate"
Hecheng xiangjiao gongye, 2023 The effects of elongation, ozone volume concentration, relative humidiy on ozone aging resistance of natural rubber (NR) vulcanizates had been investigated. A quick evaluation method of ozone aging resistance for NR vulcanizate was established.

The Elongation of Ovococci [PDF]
Microbial Drug Resistance, 2014 The morphogenesis of ovococci has been reviewed extensively. Recent results have provided new insights concerning the mechanisms of elongation in ovoid bacteria. We present here the proteins involved in the elongation (firmly established and more or less hypothetical) and discuss the relationship between elongation and division of ovococci.

Transcription elongation [PDF]
Transcription, 2017 This review is focused on recent progress in understanding how Escherichia coli RNAP polymerase translocates along the DNA template and the factors that affect this movement. We discuss the fundamental aspects of RNAP translocation, template signals that influence forward or backward movement, and host or phage factors that modulate translocation.

Collagen polarization promotes epithelial elongation by stimulating locoregional cell proliferation
eLife, 2021 Epithelial networks are commonly generated by processes where multicellular aggregates elongate and branch. Here, we focus on understanding cellular mechanisms for elongation using an organotypic culture system as a model of mammary epithelial anlage ...

Transcription, 2012 The conserved multi-subunit Elongator complex was initially described as a RNA polymerase II (RNAPII) associated transcription elongation factor, but since has been shown to be involved a variety of different cellular activities. Here, we summarize recent developments in the field and discuss the resulting implications for the proposed multi ...
