[Vitamin D receptor polymorphism in the group of postmenopausal women with low bone mineral density].

Objectives: Osteoporosis is a multifactoral disease with aetiology depending from the hormonal, environmental, and genetic factors. One of the suggested candidate gene involved in the pathogenesis is the polymorphic gene encoding for vitamin D receptor (VDR). VDR polymorphism was connected with bone mineral density (BMD) and correlated with onset of osteoporosis.

Fetal superior mesenteric artery blood flow velocimetry in normal and high-risk pregnancy.

The Aim: To record blood flow velocimetry in the fetal superior mesenteric artery in normal pregnancy and to evaluate if blood flow recordings in the vessel might predict adverse outcome in high-risk pregnancy.

Methods: The fetal superior mesenteric artery blood velocimetry was recorded in a cross sectional manner in 75 normal pregnancies between 27 and 41 weeks of gestation. Reference curves were performed for pulsatility and resistance indices.
