Associations of sperm DNA fragmentation with lifestyle factors and semen parameters of Saudi men and its impact on ICSI outcome

open access: yesReproductive Biology and Endocrinology, 2018
Background Male factor infertility is quite common as 30–50% of infertility cases are due to sperm defects. The high sperm DNA fragmentation is one of the causes of male factor infertility.

Sperm DNA fragmentation in Chinese couples with unexplained recurrent pregnancy loss

open access: yesAsian Journal of Andrology, 2020
We aimed to study the association between sperm DNA fragmentation and recurrent pregnancy loss (RPL) in the Chinese population via a retrospective observational study of Chinese couples who had experienced RPL between May 2013 and August 2018.

Petal Senescence: New Concepts for Ageing Cells [PDF]

open access: yes, 2009
Senescence in flower petals can be regarded as a form of programmed cell death (PCD), being a process where cells or tissues are broken down in an orderly and predictable manner, whereby nutrients are re-used by other cells, tissues or plant parts.

Fertilization capacity with rainbow trout DNA-damaged sperm and embryo developmental success [PDF]

open access: yes, 2010
Mammalian spermatozoa undergo a strong selection process along the female tract to guarantee fertilization by good quality cells, but risks of fertilization with DNA-damaged spermatozoa have been reported.

Assessment of heavy metals and its impact on DNA fragmentation in different fish species [PDF]

open access: yesBrazilian Journal of Biology
This study was conducted to assess water pollution by examining DNA fragmentation in selected fish organs (kidney, liver, gills, and muscle tissue) from Wallago attu, Sperata sarwari, Vulgaris vulgaris, and Labeo rohita collected from a known polluted ...

Environmental variables, habitat discontinuity and life history shaping the genetic structure of Pomatoschistus marmoratus [PDF]

open access: yes, 2014
Coastal lagoons are semi-isolated ecosystems exposed to wide fluctuations of environmental conditions and showing habitat fragmentation. These features may play an important role in separating species into different populations, even at small spatial

Rapid assessment of the effect of ciprofloxacin on chromosomal DNA from using an in situ DNA fragmentation assay [PDF]

open access: yes, 2009
Background Fluoroquinolones are extensively used antibiotics that induce DNA double-strand breaks (DSBs) by trapping DNA gyrase and topoisomerase IV on DNA.

Only complete rejoining of DNA strand breaks after UVC allows K562 cell proliferation and DMSO induction of erythropoiesis [PDF]

open access: yes, 2008
DNA strand breaks are early intermediates of the repair of UVC-induced DNA damage, however, since they severely impair cellular activities, their presence should be limited in time.
