Angiogenic factors in women ten years after severe very early onset preeclampsia.

Background: Women with a history of mainly severe and early onset preeclampsia have an increased risk of future cardiovascular disease. During these complicated pregnancies increased levels of anti-angiogenic factors can be found. We hypothesize that women with a history of severe very early onset preeclampsia still have increased levels of these biomarkers years after this pregnancy, resulting in increased risk for cardiovascular disease.

The effect of multidisciplinary lifestyle intervention on the pre- and postprandial plasma gut Peptide concentrations in children with obesity.

Objective. This study aims to evaluate the effect of a multidisciplinary treatment of obesity on plasma concentrations of several gut hormones in fasting condition and in response to a mixed meal in children. Methods.

E-selectin is elevated in cord blood of South Asian neonates compared with Caucasian neonates.

Objective: To test the hypothesis that the increased risk of type 2 diabetes mellitus and coronary artery disease in South Asian subjects could be caused by the presence of endothelial dysfunction in early life. We studied markers of endothelial dysfunction in umbilical cord blood of South Asian neonates and compared these with that of Caucasian control subjects.

Study Design: From South Asian (n = 57) and Caucasian (n = 21) neonates, cord blood was collected and levels of glucose, insulin, lipids, and markers of endothelial dysfunction (E-selectin, intercellular adhesion molecule 1, vascular cell adhesion molecule 1) and inflammation (C-reactive protein) were measured.

Delayed onset of the diurnal melatonin rise in patients with Huntington's disease.

Sleep disturbances are very prevalent in Huntington's disease (HD) patients and can substantially impair their quality of life. Accumulating evidence suggests considerable dysfunction of the hypothalamic suprachiasmatic nucleus (SCN), the biological clock, in both HD patients and transgenic mouse models of the disease. As melatonin has a major role in the regulation of sleep and other cyclical bodily activities and its synthesis is directly regulated by the SCN, we postulated that disturbed SCN function is likely to give rise to abnormal melatonin secretion in HD.

Celecoxib enhances doxorubicin-induced cytotoxicity in MDA-MB231 cells by NF-kappaB-mediated increase of intracellular doxorubicin accumulation.

Non-steroidal anti-inflammatory drugs (NSAIDs) and cyclo-oxygenase (COX) inhibitors are anti-inflammatory agents that have also shown to be useful in anticancer therapy. In the present study, we show that the specific COX-2 inhibitor celecoxib enhances the inhibitory effect of doxorubicin (dox) on human MDA-MB231 breast tumour growth in vivo and in vitro. We also found that celecoxib increased the intracellular accumulation and retention of dox in vitro.

Bone morphogenetic proteins stimulate angiogenesis through osteoblast-derived vascular endothelial growth factor A.

During bone formation and fracture healing there is a cross-talk between endothelial cells and osteoblasts. We previously showed that vascular endothelial growth factor A (VEGF-A) might be an important factor in this cross-talk, as osteoblast-like cells produce this angiogenic factor in a differentiation-dependent manner. Moreover, exogenously added VEGF-A enhances osteoblast differentiation.
