Threatened miscarriage is a common complication of pregnancy. Despite initial viability confirmation by ultrasound scan, some of these patients had further spontaneous abortion. A highly sensitive and specific biomarker would be useful to determine the outcome of pregnancy and to prevent emotional impact to these women. A prospective 14-month cohort study was conducted in the Obstetrics and Gyn...
We have studied maternal serum free beta-hCG and PAPP-A, and fetal nuchal translucency (NT) in a series of 46 cases of fetal Turner's syndrome, 13 cases of other sex chromosomal anomalies and compared these with 947 control pregnancies in the first trimester. In cases of Turner's syndrome (45,X) the median fetal NT was significantly higher than in controls (4.76 MoM), the median PAPP-A was sign...
INTRODUCTION Several studies suggested an association between first trimester biochemical markers (PAPP-A and ß-HCG) and infants below 10th percentile. Our goal was to describe this relationship of biochemical markers with small-for-gestational-age fetuses in our population. MATERIAL AND METHODS Retrospective analytic study of 2 035 pregnant women that underwent first-trimester screening in t...
Intrauterine growth restriction is the cause of significant increases in perinatal mortality, morbidity and problems development newborns infants. The leading place this pathology not accidental, because according to various authors, frequency loss associated with it from 19 287‰ more, level - 58.7 88.0%.The objective: To determine certain serum ultrasound markers during first trimester pregnan...
OBJECTIVE To examine the levels of free beta-human chorionic gonadotrophin (free beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in second-trimester maternal serum from pregnancies affected by trisomy 13 and compare these with the known reduced levels of these markers in first-trimester cases in an attempt to better understand the pathophysiology of changes in marker levels in chro...
In vitro transcorneal permeation of diclofenac from oil drops was studied using freshly excised goat cornea. The maximum apparent corneal permeability coefficient (Papp) was obtained with 0.2% (w/v) diclofenac drops in sesame oil followed by safflower oil, while formulation in castor oil provided minimal Papp. The addition of benzyl alcohol, a preservative, in oil drops, increased the Papp valu...
BACKGROUND We assessed whether adding the biomarkers Pregnancy Associated Plasma Protein-A (PAPP-A) and Placental Growth Factor (PlGF) to maternal clinical characteristics improved the prediction of a previously developed model for gestational hypertension in a cohort of Ghanaian pregnant women. METHODS This study was nested in a prospective cohort of 1010 pregnant women attending antenatal c...
The IGF-1 system is dynamic and complex,1,2 involving at least 6 IGF-1–binding proteins (IGFBP-1 through -6) and several binding protein–related proteases,1 including pregnancy-associated plasma protein-A (PAPP-A). The latter promotes IGF-1 bioavailability by cleaving IGFBP-4 and -5.3 Acute coronary syndromes have been associated with raised PAPP-A concentrations in blood, leading to the interp...
Uncariae Ramulus Cum Uncis (URCU) is a widely used traditional Chinese medicine, and is reported to have various central nervous system effects. Alkaloids have been demonstrated to be the predominant pharmacological active components of URCU. In order to evaluate the blood-brain barrier (BBB) permeability and transport mechanism of six typical indole alkaloids from URCU, the MDCK-pHaMDR cell mo...
Pregnancy associated plasma protein A2 (PAPP-A2) is a protease of insulin-like growth factor binding protein 5 and is receiving increasing attention for its roles in pregnancy and postnatal growth. The goals of the present study were to characterize the effects of PAPP-A2 deletion on bone size and shape in mice at 10 weeks of age, and to determine whether Pappa2 is the gene responsible for a pr...
