Iron deficiency is frequently seen in patients with end-stage renal disease, particularly in those treated by dialysis, this is because of an impairment in gastrointestinal absorption and ongoing blood losses or alternatively, due to an impaired capacity to mobilize iron from its stores, called functional iron deficiency. Therefore, these patients may(More)
BACKGROUND Aromatase inhibition has been proposed as a potential approach for growth enhancement in children with short stature, but detailed animal studies are lacking. AIM To assess the effect and potential adverse effects of aromatase inhibition on growth in female rats. METHODS Prepubertal Wistar rats received intramuscular injections with placebo(More)
BACKGROUND Estrogen deficiency induced by aromatase inhibitors may be a novel treatment modality for growth enhancement in short children, but may have adverse effects on bone, brain and reproduction. AIM To assess growth effects and potential adverse effects of aromatase inhibition in male rats. METHODS 26-day-old prepubertal rats received(More)
OBJECTIVE To investigate cell biological changes in calcified aortas of rats that experienced chronic renal failure. METHODS AND RESULTS Vascular smooth muscle cells have the potential to transdifferentiate to either chondrocytes or osteoblasts, depending on the molecular pathways that are stimulated. Uremia-related medial calcification was induced by(More)
Processes similar to endochondral or intramembranous bone formation occur in the vascular wall. Bone and cartilage tissue as well as osteoblast- and chondrocyte-like cells are present in calcified arteries. As in bone formation, apoptosis and matrix vesicles play an important role in the initiation of vascular calcification. Recent evidence indicates that(More)
The alternative phosphate binder calcium acetate/magnesium carbonate (CaMg) effectively reduces hyperphosphatemia, the most important inducer of vascular calcification, in chronic renal failure (CRF). In this study, the effect of low dose CaMg on vascular calcification and possible effects of CaMg on bone turnover, a persistent clinical controversy, were(More)
BACKGROUND Increased bone loss has been associated with the development of vascular calcification in patients with chronic renal failure (CRF). In this study, the effect of impaired bone metabolism on aortic calcifications was investigated in uremic rats with or without ovariectomy. METHODS CRF was induced by administration of a 0.75% adenine/2.5% protein(More)
Calcium-based phosphate binders are used to control hyperphosphatemia; however, they promote hypercalcemia and may accelerate aortic calcification. Here we compared the effect of a phosphate binder containing calcium acetate and magnesium carbonate (CaMg) to that of sevelamer carbonate on the development of medial calcification in rats with chronic renal(More)
