High levels of oxidation–reduction potential in frozen-thawed human semen are significantly correlated with poor post-thaw sperm quality
(Wiley-Blackwell, 2020)
This study examined the relationship between oxidation–reduction potential (ORP) in frozen-thawed semen and the post-thaw sperm parameters. Levels of ORP were measured in 25 samples from men presenting for routine infertility ...
The EXOTIME project: Signals in the O-C diagrams of the rapidly pulsating subdwarfs DW Lyn, V1636 Ori, QQ Vir, and V541 Hya.
(EDP Sciences, 2020)
We aim to investigate variations in the arrival time of coherent stellar pulsations due to the light-travel time effect to test for the
presence of sub-stellar companions. Those companions are the key to one possible ...
An assessment of the influence of host species, age, and thallus part on kelp-associated diatoms
(MDPI, 2020)
Diatom community composition and abundances on different thallus parts of adult and juvenile specimens of Ecklonia maxima and Laminaria pallida were examined in False Bay, South Africa, using light and scanning electron ...
Does phylogeny have an influence on the date of first description? A comparative study of the world's fishes
(Elsevier, 2020)
The process of species description is not random, and understanding the factors that influence when a species is first described (the date of first description, DoFD) allows us to target environments and/or species' traits ...
The lofar two-meter sky survey: Deep fields data release 1: II. The elais-n1 lofar deep field
(EDP Sciences, 2021)
The LOFAR Two-metre Sky Survey (LoTSS) will cover the full northern sky and, additionally, aims to observe the LoTSS deep fields to a noise level of ? 10 μJy beam-1 over several tens of square degrees in areas that have ...
The LOFAR Two-metre sky survey deep fields: The star-formation rate-radio luminosity relation at low frequencies
(EDP Sciences, 2021)
In this paper, we investigate the relationship between 150 MHz luminosity and the star-formation rate - the SFR-L150 MHz relation - using 150 MHz measurements for a near-infrared selected sample of 118 517 z < 1 galaxies. ...
Aqueous leaf extract of Sutherlandia frutescens attenuates ROS-induced apoptosis and loss of mitochondrial membrane potential in MPP+-treated SH-SY5Y cells
(University of Benin, 2020)
To investigate the neuroprotective activity of the aqueous extract of Sutherlandia frutescens (SF) against 1-methyl-4-phenylpyridinium (MPP+)-induced toxicity in SH-SY5Y neuroblastoma cells. Methods: SH-SY5Y neuroblastoma ...
Applications of computational methods in biomedical Breast cancer imaging diagnostics: A review
(MDPI, 2020)
With the exponential increase in new cases coupled with an increased mortality rate,
cancer has ranked as the second most prevalent cause of death in the world. Early detection is
paramount for suitable diagnosis and ...
The performance of photometric reverberation mapping at high redshift and the reliability of damped random walk models
(Oxford University Press, 2020)
Accurate methods for reverberation mapping using photometry are highly sought after since
they are inherently less resource intensive than spectroscopic techniques. However, the effectiveness
of photometric reverberation ...
Novel additive for sperm cryopreservation media: Holotheria parva coelomic cavity extract protects human spermatozoa against oxidative stress—A pilot study
(Wiley-Blackwell, 2020)
Cryopreservation is the most effective method for preserving semen for a long period of time. However, during the freeze–thaw process, production of reactive oxygen species (ROS) leads to a steep reduction in sperm fertility ...
