Curcumin, a potent anti-inflammatory and antioxidant agent, modulates peroxisome proliferator-activated receptor-γ signaling, a key molecule in the etiology of bronchopulmonary dysplasia (BPD). We have previously shown curcumin's acute protection against neonatal hyperoxia-induced lung injury. However, its longer-term protection against BPD is not known.(More)
The role of parathyroid hormone-related protein (PTHrP) in fetal calcium homeostasis and placental calcium transport was examined in mice homozygous for the deletion of the PTHrP gene (PTHrP-/- null; NL) compared to PTHrP+/+ (wild-type; WT) and PTHrP+/- (heterozygous; HZ) littermates. Fetal blood ionized calcium was significantly reduced in NL fetuses(More)
The effect of maternal diabetes mellitus on placental unidirectional maternofetal flux of calcium (Ca) and magnesium (Mg), calbindin9K mRNA expression, and net fetal Ca and Mg accretion has been investigated using control (C), untreated diabetic (D(O)) and insulin-treated diabetic (DI) rats. Unidirectional maternofetal flux of Ca in the D(O) group was 61(More)
The effect of maternal diabetes mellitus on renal calcium excretion in pregnant rats and their offspring has been examined in order to ascertain the role of the kidney in the disturbed calcium homeostasis of infants born to diabetic mothers. Diabetic pregnant (DP) rats exhibited severe hypercalciuria which greatly exceeded the urinary calcium losses (UCaV)(More)
PURPOSE To evaluate the performance of a previously validated prediction rule for patients presenting to the emergency department with chest pain and the potential impact of the rule on triage decisions. SUBJECTS AND METHODS In a prospective cohort study, physician investigators interviewed consecutive patients admitted for suspected acute ischemic heart(More)
PURPOSE Little is known about physicians' use of inpatient cardiac telemetry units among emergency department patients at risk for cardiac complications. We therefore studied the outcomes of patients admitted to inpatient telemetry beds to identify a subset of patients from whom cardiac monitoring could be withheld safely. SUBJECTS AND METHODS We(More)
The effects of acute maternal hyperglycaemia and hyperosmolality on maternofetal placental transfer of Ca, Mg and 51Cr-EDTA were investigated in the rat. On day 21 of gestation (term = 23 d) the fetal circulation of the in situ placenta of anaesthetised rats was perfused with a Mg-free Krebs Ringer solution and the unidirectional maternofetal fluxes of Ca(More)
Evidence is emerging that the ability of the placenta to supply nutrients to the developing fetus adapts according to fetal demand. To examine this adaptation further, we tested the hypothesis that placental maternofetal transport of calcium adapts according to fetal calcium requirements. We used a mouse model of fetal growth restriction, the(More)
Urinary pyridinoline and deoxypyridinoline, pyridinium crosslinks released during breakdown of mature collagen, might serve as useful markers of bone resorption. Before their role can be identified, reference values must be established. In this study, free pyridinoline (f-Pyr), free deoxypyridinoline (f-DPyr), and creatinine (Cr) were measured in first(More)
