DNA damage responses in the context of the cell division cycle

, 2010
During my PhD, I have investigated aspects of the DNA damage response (DDR) in the context of three different cellular scenarios: DNA damage signalling in response to double-strand breaks during mitosis, coordination of DNA replication with DNA damage ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Analysis of damage mechanisms and controlling factors of fine particle migration in unconsolidated sandstone reservoirs based on reservoir classification

Energy Science & Engineering
Particle migration in oil and gas reservoirs is a common phenomenon in the process of oil and gas development, and is considered to be an important reason for the damage of reservoir permeability and the reduction of oil and gas productivity.

Skeletal repair of extreme damage in rugose corals, Pella Formation (Mississippian, Iowa, USA)

, 2010
Little is known about predation on rugose corals or the repair of damage to rugose coral skeletons. Here we describe a population of the solitary rugose coral Amplexizaphrentis spinulosa (Milne-Edwards and Haime, 1851) from the Late Mississippian Pella ...

Persistence and Dynamics of DNA Damage Signal Amplification Determined by Microcolony Formation and Live-cell Imaging [PDF]

, 2011
Cell cycle checkpoints are essential cellular process protecting the integrity of the genome from DNA damaging agents. In the present study, we developed a microcolony assay, in which normal human diploid fibroblast-like cells exposed to ionizing ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Quantification of complex DNA damage by ionising radiation: An experimental and theoretical approach

, 2000
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Ionising radiation potentially produces a broad spectrum of damage in DNA including single and double strand breaks (ssb and dsb) and base damages.

Identifying a role for Ciz1 in the DNA damage response [PDF]

, 2011
In proliferating cells, cell cycle arrest and DNA repair are induced upon detection of DNA damage. The DNA damage response (DDR) to double strand DNA breaks is mediated by phosphatidylinositol 3-kinase-like protein kinases (PIKKs), which propagate DDR ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Formation damage effects in a horizontal wells completion [PDF]

Acta Montanistica Slovaca, 2001
Horizontal well completions are considered to reduce concerns about formation damage because the extra completion interval length in the pay zone offset production lost from reduced permeability around the wellbore.The control of sand flow from ...
