An association between vitamin D receptor (VDR) gene polymorphisms and bone mass variance has been observed in adult populations. To analyze possible association between VDR genotype and growth, we studied 589 healthy infants who were homogeneous for age, diet, and vitamin D status. The Bsm I, TaqI, and ApaI alleles' frequencies and genotypes were similar(More)
To determine whether rat osteoblasts synthesize proteins of the annexin family and to evaluate the extent to which glucocorticoids modulate the expression of annexins by these cells, osteoblasts were grown in primary cultures in the absence or presence of dexamethasone, and the expression of annexins was evaluated by immunoblotting using polyclonal(More)
We examined the regulation of arachidonic acid (AA) metabolism in primary cultures of mouse osteoblasts under steady state and after acute stimulation by PTH. Both dexamethasone-treated and untreated cells were evaluated, as glucocorticoids are known to modulate some actions of PTH in osteoblasts and to affect arachidonic acid metabolism in cells in(More)
The 12-lead electrocardiogram helps to define the arrhythmic mechanism in patients with palpitations. However, in the setting of nondocumented palpitations the value of the electrophysiologic study (EPS) needs additional investigation. We investigated the utility of the EPS in patients with nondocumented palpitations. A total of 172 patients with normal(More)
An association between vitamin D receptor (VDR) gene polymorphism and body size has been observed in infants. We hypothesized that the estradiol receptor (ER) gene is another determinant of infant growth and that the effects of the VDR and ER genotypes may interact with each other. The ER genotype (PvuII and XbaI sites), VDR genotype (BsmI site), and body(More)
To explore the possibility that defects in the regulation of expression of the messenger ribonucleic acid (mRNA) coding for the PTH receptor could be involved in pseudohypoparathyroidism type Ib (PHP-Ib), PTH-induced cAMP production and PTH/PTH-related peptide (PTH-rp) receptor mRNA expression, measured using a ribonuclease protection assay, were compared(More)
Skin fibroblasts from some patients with pseudohypoparathyroidism type Ib (PHP-Ib) are resistant to PTH. To characterize the defect producing PTH resistance in these cells and determine whether the abnormality is potentially reversible, we evaluated the ability of fibroblasts from patients with PHP-Ib to produce cAMP in response to PTH both before and after(More)
The clinical in vitro fertilization program at C.M.I. Virgen de las Nieves in Granada (Spain) was established in 1986. This letter summarizes our experience during the period from July 1986 to March 1988. The indications for IVF-ET were tubal factor (91%), male subfertility (1.5%), idiopathics (4.5%), and others (3%). The mean age of patients accepted into(More)
