Mining poly-regions in DNA.

We study the problem of mining poly-regions in DNA. A poly-region is defined as a bursty DNA area, i.e.

Modulating effect of leptin on basal and follicle stimulating hormone stimulated steroidogenesis in cultured human lutein granulosa cells.

Background: In vitro data have shown conflicting results in terms of the effect of leptin on granulosa cells steroidogenesis.

Aim: The aim of the present study was to investigate the effect of low and high doses of leptin on basal and FSH-induced steroids secretion by human luteinized granulosa cells in culture.

Materials And Methods: Granulosa cells were obtained from normal women undergoing in vitro fertilization (IVF) treatment and were cultured in serum-free conditions for 72 h.

Growth hormone, insulin-like growth factor I, and leptin interaction in human cultured lutein granulosa cells steroidogenesis.

Objective: To investigate the effect of leptin on the actions of growth hormone (GH) and insulin-like growth factor-I (IGF-I) in ovarian steroidogenesis in vitro.

Design: In vitro cell culture study.

Setting: Research laboratory of a university hospital.

BoostMap: an embedding method for efficient nearest neighbor retrieval.

This paper describes BoostMap, a method for efficient nearest neighbor retrieval under computationally expensive distance measures. Database and query objects are embedded into a vector space, in which distances can be measured efficiently. Each embedding is treated as a classifier that predicts for any three objects X, A, B whether X is closer to A or to B.

Endothelin-3 and PRL levels in the maternal and fetal circulation at delivery.

Objective: The aim of the present cross-sectional study was to test the hypothesis that endothelin-3 (ET-3) is involved in PRL secretion via systemic hormonal interaction during labor.

Materials And Methods: Fifty healthy pregnant women with singleton pregnancies were included in the present study. At delivery, blood samples were drawn from umbilical vein and artery.
