(Lippincott, Williams & Wilkins, 2013)Pienaar, C and Coetzee, B. Changes in selected physical, motor performance and anthropometric components of university-level rugby players after one microcycle of a combined rugby conditioning and plyometric training ... -
Changes in the foot strike pattern and pressure distribution when running in minimalist and traditional sport shoes
(Edizioni Minerva Medica, 2018)BACKGROUND: New trends in the use of minimalist shoes and barefoot running lead to the monitoring of movement patterns wearing sports shoes and minimalist shoes while running. Therefore, the objective was to compare the ... -
Changing the habits of Namibian community social workers: an experiment in training
(Unisa Press, 2011)Two recent studies have shown that highly effective community practitioners exhibit eight habits that set them apart from the rest. The question arose whether these habits could also be instilled in other, less effective ... -
Channel inclusion of primary alcohols in isostructural solvates of the antiretroviral nevirapine: an X-ray and thermal analysis study
(Springer, 2010)X-ray structural and thermoanalytical data for a series of solvates 2–7 of the anti-HIV drug nevirapine containing primary alcohols CH3(CH2)nOH with n = 2–7 are reported. The structures of 2–7 are based on a common ... -
Characterisation of and exposure of workers to tailings dust at South African platinum mines
(Mine Ventiliation Society of South Africa, 2009)The National Institute for Occupational Safety and Health (NIOSH) has conducted research to improve the ventilation of large-opening mines whose entries are at least 93m2 (1,000 ft2). The ventilation of large-opening mines ... -
The characteristics of compassionate care during childbirth according to midwives: a qualitative descriptive inquiry
(BMC, 2020)Abstract Background: Although compassion is considered to be of prime importance in nursing and midwifery, there is no clear understanding of what compassionate care in childbirth entails, and how midwives perceive ... -
Characterization of an alginate encapsulated LS180 spheroid model for anti-colorectal cancer compound screening
(ACS, 2020)Colorectal cancer is one of the leading causes of cancer-related deaths. A main problem for its treatment is resistance to chemotherapy, requiring the development of new drugs. The success rate of new candidate cancer drugs ... -
Characterization of personal solar ultraviolet radiation exposure using detrended fluctuation analysis
(Elsevier, 2020)Studies of personal solar ultraviolet radiation (pUVR) exposure are important to identify populations at-risk of excess and insufficient exposure given the negative and positive health impacts, respectively, of time spent ... -
Characterization of polymorph transformations that decrease the stability of tablets containing the who essential drug mebendazole
(Elsevier, 2010)This study investigated the influence of moisture and heat on the stability of mebendazole polymorph C in tablets. The polymorphic forms of mebendazole display significant differences in solubility and therapeutic efficacy ... -

(Taylor & Francis, 2020)bjective The World Health Organization has called for the development of novel drug delivery systems to combat malaria – the fourth most prevalent cause of death globally. The plausibility of utilizing hot fusion to prepare ... -
Characterization of the cell-free DNA released by cultured cancer cells
(Elsevier, 2016)The most prominent factor that delays the translation of cell-free DNA (cfDNA) analyses to clinical practice is the lack of knowledge regarding its origin and composition. The elucidation of the former is complicated by ... -
Chemical composition, but not specific surface area, affects calcium retention of nanostructured calcium compounds in growing rats
(Oxford Univ Press, 2017)Background: Low dietary calcium intake and bioavailability may adversely affect bone health. Reducing the size of calcium compounds increases their specific surface area (SSA, expressed as m2/g) and may increase calcium ... -

Chronic defensiveness and neuroendocrine dysfunction reflect a novel cardiac troponin T cut point: the SABPA study
(Elsevier, 2017)Background Sympatho-adrenal responses are activated as an innate defense coping (DefS) mechanism during emotional stress. Whether these sympatho-adrenal responses drive cardiac troponin T (cTnT) increases are unknown. ... -
Chronic depression symptoms and salivary NOx are associated with retinal vascular dysregulation: the SABPA study
(Elsevier, 2016)Background Depression has been associated with impaired nitric oxide (NO)-mediated vasodilation and vascular dysregulation (VD). Whether depression and NO levels will disturb retinal haemodynamics is not clear. Objectives ... -
Chronic depression symptoms desensitize renin activity to protect against volume-loading hypertension in Blacks: the SABPA study
(Elsevier, 2018)Background Low-renin levels in Blacks have been associated with volume-loading hypertension (HT). Depression symptoms, frequently co-occurring with vascular dysregulation, might reflect a disturbed renin-angiotensin-ald ... -
