[Reducing rate of macrosomia in Iceland in relation to changes in the labor induction rate].

Aim: Diabetes and prolonged pregnancy are risk factors of macrosomia. The aim was to explore the relationship between the increased rate of labor induction and macrosomia in Iceland. Changes in the incidence proportion of macrosomia was estimated by gestational age.

Follistatin-related gene expression, but not follistatin expression, is decreased in human endometrial adenocarcinoma.

Objective: Activin A is a multifunctional growth and cell differentiation factor produced by normal endometrium, and secreted in high amounts by endometrial adenocarcinoma. In the present study we evaluated the expression of two inhibitory activin A ligands, follistatin and follistatin-related gene (FLRG), in endometrial adenocarcinoma and in age-matched healthy human endometrium.

Design And Methods: Atropic menopausal (n=13) and tumoral (n=9 adenocarcinoma) tissues were processed to evaluate mRNA expression levels (by semiquantitative RT-PCR) and peptide localization (by immunohistochemistry).

Paracrine regulation of endometrial function: interaction between progesterone and corticotropin-releasing factor (CRF) and activin A.

Under the influence of ovarian steroid hormones, endometrial cells aer able to produce a wide variety of growth factors and peptide hormones that area believed to promote: (1) physiological growth and differentiation during the endometrial cycle; (2) decidualization, an essential preparative event for establishment of pregnancy; and (3) pathological growth and differentiation in endometriosis and cancer. Among the local factors produced by the human endometrium, corticotropin-releasing factor (CRF) and activin A have been evaluated in terms of localization and effects. CRF is a neuropeptide expressed by the epithelial and stromal cells of the human endometrium in increasing amounts from the endometrial proliferative to the secretory phase.

The gene encoding phosphodiesterase 4D confers risk of ischemic stroke.

We previously mapped susceptibility to stroke to chromosome 5q12. Here we finely mapped this locus and tested it for association with stroke. We found the strongest association in the gene encoding phosphodiesterase 4D (PDE4D), especially for carotid and cardiogenic stroke, the forms of stroke related to atherosclerosis.
