Effect of Novartis Access on availability and price of non-communicable disease medicines in Kenya: A cluster-randomised controlled trial
(Elsevier, 2019)Novartis Access is a Novartis programme that offers a portfolio of non-communicable disease medicines at a wholesale price of US$1 per treatment per month in low-income and middle-income countries. We evaluated the effect ... -
The effect of occupational-related low back pain on the functional activities among manual workers in construction companies
(University of the Western Cape, 2010)INTRODUCTION: Low back pain is the most prevalent musculoskeletal condition and one of the most common causes of disability in the world. The disability resulting from low back pain continues to plague the construction ... -
The effect of occupationally-related low back pain on functional activities among male manual workers in a construction company in Cape Town, South Africa
(The South African Society of Occupational Medicine, 2012)This study determined the prevalence as well as the effect of occupationally-related low back pain on the functional activities of workers in a construction company in Cape Town. A cross-sectional, descriptive survey ... -
Effect of pH on the structure and stability of irisin, a multifunctional protein: Multispectroscopic and molecular dynamics simulation approach
(Elsevier, 2021-12)Irisin is a potential therapeutic agent to prevent or treat various metabolic-related disorders and neurodegenerative diseases viz. Alzheimer’s disease (AD). In this study, we have employed a multispectroscopic approach ... -
Effect of physical activity on coronary heart disease risk factors among firefighters: a scoping review protocol
(BMJ open, 2023)Introduction: Physical activity interventions have been used for various health conditions, including cardiovascular disease. However, the literature is still limited regarding the effect of physical activity on coronary ... -
Effect of pomegranate (Punica granatum L) peel powder meal dietary supplementation on antioxidant status and quality of breast meat in broilers
(Elsevier, 2020)This study examined the antioxidant status and quality of breast meat in broiler birds fed diets supplemented with pomegranate peel powder meal (PPPM). During the 35-d feeding trial, broiler birds were fed six experimental ... -
The effect of PtRuIr nanoparticle crystallinity in electrocatalytic methanol oxidation
(MDPI, 2013)Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as ... -
The effect of religion on parenting in order to guide parents in the way they parent: a systematic review
(Taylor & Francis, 2017)Religion has a growing influence on parenting, and there remains a need to understand the influence of religious values in order to inform parents, and other professional bodies, on how religious beliefs can influence ... -
