Self-similarity of human protein interaction networks: a novel strategy of distinguishing proteins
(2015)The successful determination of reliable protein interaction networks (PINs) in several species in the post-genomic era has hitherto facilitated the quest to understanding systems and structural properties of such networks. ... -
Sella turcica morphology in patients with genetic syndromes: Protocol for a systematic review
(JMIR Publications Inc., 2020)Background: The sella turcica is an important anatomical reference used in orthodontics and the evaluation of craniofacial growth. Studies have found an association between variations in sella turcica morphology in patients ... -
Semantic interrogation of a multi knowledge domain ontological model of tendinopathy identifies four strong candidate risk genes
(Nature Research, 2016)Tendinopathy is a multifactorial syndrome characterised by tendon pain and thickening, and impaired performance during activity. Candidate gene association studies have identified genetic factors that contribute to ... -
Semi-analytic forecasts for jwst – ii. Physical properties and scaling relations for galaxies at z = 4–10
(Oxford academic, 2019)The long anticipated James Webb Space Telescope (JWST) will be able to directly detect large samples of galaxies at very high redshift. Using the well-established, computationally efficient Santa Cruz semi-analytic model, ... -
Semi-analytic forecasts for JWST – IV. Implications for cosmic reionization and LyC escape fraction
(Oxford University Press, 2020-06-20)Galaxies forming in low-mass haloes are thought to be primarily responsible for reionizing the Universe during the first billion years after the big bang. Yet, these haloes are extremely inefficient at forming stars in ... -
Semi-analytic forecasts for Roman – the beginning of a new era of deep-wide galaxy surveys
(Oxford University Press, 2023)The Nancy Grace Roman Space Telescope, NASA’s next flagship observatory, will redefine deep-field galaxy survey with a field of view two orders of magnitude larger than Hubble and an angular resolution of matching quality. ... -
Seminal oxidation–reduction potential levels are not influenced by the presence of leucocytospermia
(Wiley-Blackwell, 2020)Oxidative stress (OS) is characterised by an excessive amount of reactive oxygen species (ROS) which negatively affect sperm functions. In this study, the influence of leucocytes on seminal oxidation–reduction potential ... -
The semiotic ecology of linguistic landscapes in rural Zambia
(John Wiley & Sons LTD., 2015)In addressing the dearth in studies on linguistic/semiotic landscapes in oral-language dominant rural communities, we use the notion of repurposing to show how people from rural areas of Livingstone and Lusaka in Zambia ... -
A semiotic notion of transcendence
(Pretoria University, 2013)As the title indicates, this contribution explores a semiotic notion of transcendence. It is argued that experiences of transcendence are quite common and that notions of transcendence are highly significant since they ... -
Semiotic signature of transformation in a diachronic corpus of a South African political party
(Benjamins, 2019)Corpus analysis has become established as an approach to the study of language description or for applied pursuits in language teaching, terminology, and so on. However, because of the social indexicalities of language ... -
Semiquantitative promoter methylation of MLH1 and MSH2 genes and their impact on sperm DNA fragmentation and chromatin condensation in infertile men
(Blackwell Publishing Ltd, 2021)To investigate the semiquantitative methylation alterations of MLH1 and MSH2 and the possible association among methylation of MLH1 and MSH2, sperm DNA fragmentation and sperm chromatin condensation in idiopathic ... -
The Sen-Nussbaum diagram of article 11(3) of the African Charter on the Rights and Welfare of the Child: Facilitating the relationship between access to education and development
(Scielo South Africa, 2021)The right to education is an infinitely important right, the benefits of which are boundless. In the case of children, this position is even more emphasised. The right to education has been described as a 'gateway right', ... -
