Maturitas
. 2000 Nov;
36(3):195-201.
PMID: 11063901
Objectives: there is considerable uncertainty about the underlying cause of decreased intestinal calcium absorption that occurs in postmenopausal women. In a previous study, estrogen treatment did not result in an...

J Lab Clin Med
. 2000 Apr;
135(4):303-8.
PMID: 10779045
There is considerable evidence that the extracellular fluid volume (ECV) may change in disease states or during longitudinal Intervention studies. Therefore, the measurement of ECV is Important for studying body...

Clin Chem
. 2000 Feb;
46(2):248-51.
PMID: 10657381
Background: Intestinal strontium absorption is becoming accepted as a clinical and diagnostic tool for assessing intestinal calcium absorption in humans. However, little is known about whether intestinal strontium absorption, like...

Clin Endocrinol (Oxf)
. 1999 Aug;
50(3):387-92.
PMID: 10435066
Objective: Impaired intestinal calcium absorption in postmenopausal women is often indirectly linked to decreased serum 1,25(OH)2D or to intestinal resistance to its action rather than directly to low circulating oestrogen...

. 1999 Jul;
14(7):1197-202.
PMID: 10404021
Studies were carried out to examine the mechanism of action of estrogen on intestinal calcium absorption in the rat. Three-month-old Wistar rats were sham-operated or ovariectomized (OVX). They were fed...

Am J Physiol
. 1997 Mar;
272(3 Pt 1):E422-8.
PMID: 9124548
The applicability of stable strontium as a marker for measuring intestinal calcium absorption is mainly dependent on the validity of the assumption that calcium and strontium are absorbed with a...

Sips A, van der Vijgh W, Barto R, Netelenbos J
Br J Clin Pharmacol
. 1996 Jun;
41(6):543-9.
PMID: 8799520
1. The absorption kinetics of orally administered strontium chloride and its reproducibility were investigated in healthy volunteers after administering strontium either under fasting conditions (study I, n = 8) or...

Sips A, van der Vijgh W, Barto R, Netelenbos J
Clin Chem
. 1995 Oct;
41(10):1446-50.
PMID: 7586515
Calcium absorption tests have rarely been validated for being representative for absolute bioavailability (true absorption) or for intraindividual variation. Therefore, we investigated the reproducibility of the absolute bioavailability of strontium...

Clin Chem
. 1995 Aug;
41(8 Pt 1):1159-63.
PMID: 7628091
For long-term pharmacokinetic studies in humans as well as in experimental animals, an analysis of strontium (Sr) with a low detection limit and high sensitivity is necessary. The data presented...
