The effects of residual platelets in plasma on plasminogen activator inhibitor-1 and plasminogen activator inhibitor-1-related assays
(PLOS, 2017)Due to controversial evidence in the literature pertaining to the activity of plasminogen activator inhibitor-1 in platelets, we examined the effects of residual platelets present in plasma (a potential pre-analytical ... -
Effects of seated and standing cold water immersion on recovery from repeated sprinting
(Taylor & Francis, 2015)This study investigated the effects of two different hydrostatic pressures (seated or standing) during cold water immersion at attenuating the deleterious effects of strenuous exercise on indices of damage and recovery. ... -
The effects of stirring, population levels and a potential anti-nematodal product on the respiration of second-stage juveniles of Meloidogyne incognita measured with different technology
(Brill, 2016)The oxygen consumption rate (OCR) of Meloidogyne incognita second-stage juveniles (J2) was measured using polarographic oxygen sensor (POS) and fibre-optic oxygen sensor (FOS) technology. The effect of stirring speed on ... -
Effects of strategic management and labour unions in organizational productivity for the South African broadcasting corporation
(SAAPAM, 2014)The relationship between strategic management and labour unions has proven to be significant towards organisational productivity. This relationship has the power of influencing the employees positively or negatively depending ... -
Effects of strength training on postpubertal adolescent distance runners
(Wolters Kluwer, 2018)Purpose Strength training activities have consistently been shown to improve running economy (RE) and neuromuscular characteristics, such as force-producing ability and maximal speed, in adult distance runners. However, ... -
Effects of strength training on the physiological determinants of middle- and long-distance running performance: a systematic review
(Springer, 2018)Background Middle- and long-distance running performance is constrained by several important aerobic and anaerobic parameters. The efficacy of strength training (ST) for distance runners has received considerable attention ... -
Effects of the cosurfactant 1-butanol and feed composition on nanoparticle properties
(Wiley, 2008)The concentration of the cosurfactant 1-butanol (BuOH) determined the polymer weight and size for a series of poly(styrene-co-methyl methacrylate)s (P(St-co-MMA)) synthesized by the free-radical (o/w) microemulsion technique. ... -
Effects of the organochlorine p,p’-DDT on MCF-7 cells: investigating metabolic and immune modulatory transcriptomic changes
(Elsevier, 2019)The organochlorine pesticide dichloro-diphenyl-trichloroethane (DDT) is persistent in the environment and leadsto adverse human health effects. High levels in breast milk pose a threat to both breast tissue and nursing ... -
Effects of various dissipation range onset models on the 26-day variations of low-energy galactic cosmic-ray electrons
(Elsevier, 2010)The effect of various models presented by Leamon et al. (2000) for the dissipation range cutoff wavenumber on the 26-day variations of galactic cosmic-ray electrons in a Fisk-Parker hybrid field is investigated, by means ... -
Efficacy of Bacillus thuringiensis sprays and cotton cultivars expressing cry proteins in the control of Earias biplaga (Walker) (Lepidoptera: Noctuidae)
(BioOne, 2017)Earias biplaga (Walker) (Lepidoptera: Noctuidae) forms part of the bollworm pest complex of cotton in South Africa. Genetically modified Bt cotton that expresses Cry insecticidal proteins successfully controls the bollworm ... -
Efficacy of Bt Maize for control of Spodoptera frugiperda (Lepidoptera: Noctuidae) in South Africa
(Oxford Univ Press, 2019)Spodoptera frugiperda (J.E. Smith) is an invasive pest species that threatens maize production by small holder farmers in Africa. Bt maize that express Cry proteins have been used effectively for control of this pest in ... -
Efficacy of fish- and hydramethylnon-based baits for conservation of the African weaver ant Oecophylla longinoda (Hymenoptera: Formicidae) during cashew off-seasons in Tanzania
(Cambridge Univ Press, 2015)The efficacy of fish- and hydramethylnon-based baits for conservation of the African weaver ant (AWA) Oecophylla longinoda Latreille was evaluated at orchards in Bagamoyo and Mkuranga districts, Coast region of Tanzania, ... -
The efficacy of protein supplementation during recovery from muscle-damaging concurrent exercise
(NRC Research Press, 2017)This study investigated the effect of protein supplementation on recovery following muscle-damaging exercise, which was induced with a concurrent exercise design. Twenty-four well-trained male cyclists were randomised to ... -
Efficacy of the African weaver ant Oecophylla longinoda (Hymenoptera: Formicidae) in the control of Helopeltis spp. (Hemiptera: Miridae) and Pseudotheraptus wayi (Hemiptera: Coreidae) in cashew crop in Tanzania
(Wiley, 2013)BACKGROUND:Cashew, Anacardiumoccidentale, is aneconomically important cash crop formorethan 300 000 rural households in Tanzania. Its production is, however, severely constrained by infestation by sap-sucking insects such ... -
Efficiency behaviour of kernel-smoothed kernel distribution function estimators
(SASA, 2020)The asymptotic mean integrated squared error (AMISE) and the kernel efficiency (KE) of kernel distribution function estimators are well studied. In this note we define new nonparametric distribution function estimators by ... -
Efficient waste reduction algorithms based on alternative underestimates for the modified Wang method
(Operations Research Society of South Africa, 2014)This paper is concerned with wastage reduction in constrained two-dimensional guillotine- cut cutting stock problems, often called trim loss problems. A number of researchers report in the literature on algorithmic ... -
Efflux as a mechanism of antimicrobial drug resistance in clinical relevant microorganisms: the role of efflux inhibitors
(Taylor & Francis, 2017)Introduction: Microbial resistance against antibiotics is a serious threat to the effective treatment of infectious diseases. Several mechanisms exist through which microorganisms can develop resistance against antimicrobial ... -
Efflux pumps genes of clinical origin are related to those from fluconazole-resistant Candida albicans isolates from environmental water
(IWA Publishing, 2018)Efflux pumps coded for by CDR1, CDR2, FLU1 and MDR1 genes could be responsible for the observed resistant phenotypes in azole-resistant Candida albicans from environmental water. This was demonstrated for clinical isolates. ... -
