Pretorius, Etheresia; Mbotwe, Sthembile; Bester, Janette; Robinson, Christopher J.; Kell, Douglas B. (The Royal Society, 2016)It is well known that a variety of inflammatory diseases are accompanied by hypercoagulability, and a number of more-or-less longer-term signalling pathways have been shown to be involved. In recent work, we have suggested ...

Pretorius, Etheresia; Oberholzer, Hester Magdalena; Van der Spuy, Wendy Jeannette; Meiring, Johannes H. (Springer, 2010-01)During aging, changes in vasculature, haemostasis and endothelium, including alterations of platelets, coagulation and fibrinolytic factors, occur. Research has also reported that healthy, aged individuals have heightened ...

Pretorius, Etheresia; Bester, Janette; Kell, Douglas B. (IOS Press (open access), 2016-06)The progression of Alzheimer’s disease (AD) is accompanied by a great many observable changes, both molecular and physiological. These include oxidative stress, neuroinflammation, and (more proximal to cognitive decline) ...

Nielsen, Vance G.; Pretorius, Etheresia; Bester, Janette; Jacobsen, Wayne K.; Boyle, Patrick K.; Reinhard, Joao P. (Bentham Science, 2015-01)Alzheimer’s disease (AD) is a significant source of morbidity and mortality for millions of people worldwide, and multiple potential etiologies have been postulated to contribute to AD. Among these, spontaneous cerebral ...

Buys, A.V. (Antonia Vergina); Van Rooy, Mia-Jeanne; Soma, Prashilla; Van Papendorp, D.H. (Dirk Hermanus), 1949-; Lipinski, Boguslaw; Pretorius, Etheresia (BioMed Central, 2013-01-28)Red blood cells (RBCs) are highly deformable and possess a robust membrane that can withstand shear force. Previous research showed that in diabetic patients, there is a changed RBC ultrastructure, where these cells ...
-
Pretorius, Etheresia (San Lucas Medical, 2010)Estrogen plays an important role during the life of a healthy female and impacts on the coagulation profile. Products that impact on the hemostatic health of women include contraception, as well as using hormone replacement ...
