Is there a link between the pathogenic human Coronavirus envelope protein and immunopathology? A review of the literature
(Frontiers Media S.A., 2020)Since the severe acute respiratory syndrome (SARS) outbreak in 2003, human coronaviruses (hCoVs) have been identified as causative agents of severe acute respiratory tract infections. Two more hCoV outbreaks have since ... -
Is there evolution in the infrared Tully–Fisher relation? Comparing two linear regressions
(Oxford University Press, 2009)In a recent paper, Puech and co-workers compared K-band Tully–Fisher relations derived for nearby and distant galaxies, respectively. They concluded that the two relations differ, and deduced that there is evolution in ... -
Is there plagiarism in the most influential publications in the field of andrology?
(Wiley, 2019)Plagiarism is a common form of academic misconduct that extensively jeopardises the quality of scientific publication. The purpose of this study is to determine the extent of plagiarism in the most influential andrology ... -

Is your garden green? How to be kind to your garden
(Botanical Society of South Africa, 2008)Years ago, there was plenty of open, natural veld surrounding our towns and it was rich in wildlife. As towns expanded the natural veld and wildlife shrank into patches between towns, factories and farm land. With this ... -
The Ism between endothelial cilia and endothelial nanotubules is an evolving concept in the genesis of the BBB
(MDPI, 2022)The blood–brain barrier (BBB) is fundamental in maintaining central nervous system (CNS) homeostasis by regulating the chemical environment of the underlying brain parenchyma. Brain endothelial cells (BECs) constitute ... -
Isolation and characterisation of cellulose nanocrystal obtained from sugarcane peel
(Rasayan Journal, 2020)This work was aimed at developing efficient and stable cellulose nanocrystal (CNC) from sugarcane peel, which has been of growing concern as a potential for various industrial applications and providing a solution to the ... -
Isolation and characterization of lytic proteus virus 309
(MDPI, 2022)Proteus mirabilis is frequently associated with complicated urinary tract infections (UTIs) and is the main cause of catheter-associated urinary tract infections (CAUTIs). Treatment of such infections is complicated and ... -
Isolation and characterization of strain exiguobacterium sp. Krl4, a producer of bioactive secondary metabolites from a Tibetan glacier
(MPDI, 2021)Extremophilic microorganisms represent a unique source of novel natural products. Among them, cold adapted bacteria and particularly alpine microorganisms are still underexplored. Here, we describe the isolation and ... -
Isoscalar giant monopole strength in 58Ni, 90Zr, 120Sn and 208Pb
(American Physical Society, 2023)Inelastic α-particle scattering at energies of a few hundred MeV and very-forward scattering angles including 0° has been established as a tool for the study of the isoscalar giant monopole (IS0) strength distributions ... -
Isothermal dust models of Herschel-ATLAS galaxies
(Oxford University Press, 2013)We use galaxies from the Herschel-ATLAS survey, and a suite of ancillary simulations based on an isothermal dust model, to study our ability to determine the effective dust temperature, luminosity and emissivity index of ... -
Iterative mapping of marine ecosystems for spatial status assessment, prioritization, and decision support
(Frontiers Media, 2023)South Africa has taken an iterative approach to marine ecosystem mapping over 18 years that has provided a valuable foundation for ecosystem assessment, planning and decision-making, supporting improved ecosystem-based ... -
Iterative prophylactic treatment by hematin in two cases of recurrent disabling acute intern1ittent porphyria (AIP)
(Elsevier, 1989)Summary: Hematin is known as a useful drug in the treatment of acute intermittent porphyria (Al P) attacks. We have used it with success as an iterative prophylactic treatment in two cases of AIP with recurrent disabling ... -
J1615+5452: a remnant radio galaxy in the ELAIS-N1 field
(Oxford University Press, 2020)We report the discovery of a remnant radio active galactic nucleus (AGN) J1615+5452 in the field of ELAIS-N1. GMRT continuum observations at 150, 325, and 610 MHz combined with archival data from the 1.4 GHz NVSS survey ... -
Jellyfication of marine ecosystems as a likely consequence of overfishing small pelagic fishes: Lessons from the Benguela
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 2013)Changes in two contrasting ecosystems of the Benguela upwelling region, one dominated at mid-trophic level by jellyfishes (Namibia, northern Benguela ecosystem, where small pelagic fish abundance has been severely depleted) ... -
Jet feedback and the photon underproduction crisis in SIMBA
(Oxford University Press, 2020-10-01)We examine the impact of black hole jet feedback on the properties of the low-redshift intergalactic medium (IGM) in the SIMBA simulation, with a focus on the Lyα forest mean flux decrement DA. Without jet feedback, we ... -
JHKs time-series observations of a few ultracool dwarfs
(Oxford University Press, 2005)The M8.5 object SSSPM J0109−5101 has recently been shown to be both a periodic and a flaring variable, based on optical observations in the extreme red. More than 16 h of monitoring in the near-infrared (NIR) reported ... -
JL 82: a slowly pulsating hot subdwarf star in a close binary system
(Oxford University Press, 2009)JL 82 is a known binary, consisting of an sdB star and a companion which is not directly observable in the optical. Photometric measurements reported in this paper show it to variable with both the binary period (∼0.75 ...
