Prerace medical screening and education reduce medical encounters in distance road races: SAFER VIII study in 153 208 race starters
(BMJ Publishing Group, 2018)OBJECTIVES To examine the efficacy and feasibility of an online prerace medical screening and educational intervention programme for reducing medical complications in long-distance races. METHODS This was an 8-year ... -
Preservation of shortening velocity and power output in single muscle fibres from patients with idiopathic inflammatory myopathies
(Springer, 2022)Idiopathic inflammatory myopathies (IIMs) are autoimmune disorders of skeletal muscle causing weakness and disability. Utilizing single fibre contractility studies, we have previously shown that contractility is affected ... -
Prevalence of hypertension and its associated risk factors in a rural black population of Mthatha town,South Africa
(MPDI, 2021)The occurrence of hypertension has been increasing alarmingly in both low and middle-income countries. Despite acknowledging hypertension as the most common life-threatening risk factor for cardiovascular disease (CVD), a ... -
Prevalence, patterns and determinants of dyslipidaemia among South African adults with comorbidities
(Nature Research, 2022)The present study assessed the prevalence, patterns and determinants of dyslipidaemia among South African adults with multi-morbidities. In this study, 614 individuals with DM and hypertension were recruited. Dyslipidaemia ... -
Prioritization of anti-malarial hits from nature: Chemo-informatic profiling of natural products with in vitro antiplasmodial activities and currently registered anti-malarial drugs
(BMC, 2016)A large number of natural products have shown in vitro antiplasmodial activities. Early identification and prioritization of these natural products with potential for novel mechanism of action, desirable pharmacokinetics ... -
Prioritization of candidate genes for a South African family with Parkinson’s disease using in-silico tools
(Public Library of Science, 2021)Parkinson's disease (PD) is a neurodegenerative disorder exhibiting Mendelian inheritance in some families. Next-generation sequencing approaches, including whole exome sequencing (WES), have revolutionized the field of ... -
Probabilistic learning for pulsar classification
(IOP Publishing, 2022)In this work, we explore the possibility of using probabilistic learning to identify pulsar candidates. We make use of Deep Gaussian Process (DGP) and Deep Kernel Learning (DKL). Trained on a balanced training set in ... -
Probing beyond-Horndeski gravity on ultra-large scales
(2020)The beyond-Horndeski gravity has recently been reformulated in the dark energy paradigm — which has been dubbed, Unified Dark Energy (UDE). The evolution equations for the given UDE appear to correspond to a non-conservative ... -

Probing Cosmology beyond ΛCDM using the SKA
(Indian Academy of Sciences, 2023)The cosmological principle states that the Universe is statistically homogeneous and isotropic at large distance scales. Currently, there exist many observations which indicate a departure from this principle. It has ... -
Probing primordial features with the primary CMB
(Elsevier, 2019)We propose to study the imprint of features in the primordial power spectrum with the primary CMB after the subtraction of the reconstructed ISW signal from the observed CMB temperature angular power spectrum. We consider ... -
Probing reionization with LOFAR (Low Frequency Array) using 21-cm redshift space distortions
(Oxford University Press, 2013)One of the most promising ways to study the epoch of reionization (EoR) is through radio observations of the redshifted 21-cm line emission from neutral hydrogen. These observations are complicated by the fact that the ... -
Probing the bias of radio sources at high redshift
(Oxford University Press, 2013)The relationship between the clustering of dark matter and that of luminous matter is often described using the bias parameter. Here, we provide a new method to probe the bias of intermediate-to-high-redshift radio ... -
Probing the imprint of interacting dark energy on very large scales
(American Physical Society, 2015)The observed galaxy power spectrum acquires relativistic corrections from light-cone effects, and these corrections grow on very large scales. Future galaxy surveys in optical, infrared and radio bands will probe increasingly ... -
Probing the nature of the conjectured low-spin wobbling bands in atomic nuclei
(Elsevier, 2022)The precession of an atomic nucleus can be approximately described as wobbling motion, arising from the coupling of a rotation and a harmonic vibration. Recently, a number of wobbling bands were reported at low spin, which ... -
The production of hydrogen through the use of a 77 wt% Pd 23 wt% Ag membrane water gas shift reactor
(Elsevier, 2016)Hydrogen as an energy carrier has the potential to decarbonize the energy sector. This work presents the application of a palladium-silver (PdeAg) membrane-based reactor. The membrane reactor which is made from PdeAg ... -

Progesterone, myo-inositol, dopamine and prolactin present in follicular fluid have differential effects on sperm motility subpopulations
(MDPI, 2021)Considering the challenges surrounding causative factors in male infertility, rather than relying on standard semen analysis, the assessment of sperm subpopulations and functional characteristics essential for fertilization ... -
Progress in remote sensing of grass senescence: A review on the challenges and opportunities
(Institute of Electrical and Electronics Engineers, 2021)Grass senescence estimation in rangeland is particularly important for monitoring the conditions of forage quality and quantity. During senescence, grasses lose their nutrients from the leaves to the root and thereby ...
