Comparison of test performance of two commonly used multiplex assays to measure micronutrient and inflammatory markers in serum: results from a survey among pregnant women in South Africa
Chimhashu, Tsitsi; Verhoef, Hans; Symington, Elizabeth; Zandberg, Lizelle; Baumgartner, Jeannine; Malan, Linda; Smuts, Cornelius; Feskens, Edith; Melse-Boonstra, Alida (Cambridge University Press, 2024)The combined sandwich-ELISA (s-ELISA; VitMin Lab, Germany) and the Quansys Q-Plex™ Human Micronutrient Array (7-Plex) are multiplex serum assays that are used to assess population micronutrient status in low-income ... -
Evaluation of the cytotoxic properties, gene expression profiles and secondary signalling responses of cultured cells exposed to fumonisin B1, deoxynivalenol and zearalenone mycotoxins
Wentzel, Johannes F.; Lombard, Martani J.; Du Plessis, Lissinda H.; Zandberg, Lizelle (Springer, 2017)Mycotoxins are toxic secondary metabolites produced by a range of fungi and are common contaminants of agricultural crops. These toxins are chemically diverse and structurally stable, enabling them to enter the food ... -
Fibrinogen and clot-related phenotypes determined by fibrinogen polymorphisms: independent and IL-6-interactive associations
Cronjé, H. Toinét; Nienaber-Rousseau, Cornelie; Zandberg, Lizelle; De Lange, Zelda; Pieters, Marlien (PLoS, 2017)Interleukin-6 (IL-6) induces the expression of fibrinogen, and polymorphic variation within the fibrinogen genes is believed to alter the magnitude of this expression. The identification of the functional relevance of ... -
Gene interactions observed with the HDL-c blood lipid, intakes of protein, sugar and biotin in relation to circulating homocysteine concentrations in a group of black South Africans
Du Plessis, Jacomina P.; Melse-Boonstra, Alida; Zandberg, Lizelle; Nienaber-Rousseau, Cornelie (Elsevier, 2020)Background Elevated homocysteine (Hcy) is associated with several pathologies. Gene–diet interactions related to Hcy might be used to customize dietary advice to reduce disease incidence. To explore this possibility, we ... -
Nutrition during pregnancy and early development (NuPED) in urban South Africa: a study protocol for a prospective cohort
Symington, Elizabeth A.; Baumgartner, Jeannine; Malan, Linda; Zandberg, Lizelle; Ricci, Cristian; Smuts, Cornelius M. (BioMed Central, 2018)Background Adequate nutrition during pregnancy is important to ensure optimal birth outcomes, maternal health and offspring development. However, little is known about the dietary intake and nutritional status of pregnant ... -
Nutritional status of Tajik children and women: transition towards a double burden of malnutrition
Barth-Jaeggi, Tanja; Zandberg, Lizelle; Bahruddinov, Mutribjon; Kiefer, Sabine; Rahmarulloev, Sherali (Wiley, 2019)The double burden of malnutrition, an emerging concern in developing countries, can exist at various levels: individual, household, and population. Here, we explore the nutritional status of Tajik women (15–49 years) and ...
