Haplotype diversity and population structure in cultivated and wild barley evaluated for Fusarium head blight responses.

Fusarium head blight (FHB) is a threat to barley (Hordeum vulgare L.) production in many parts of the world. A number of barley accessions with partial resistance have been reported and used in mapping experiments to identify quantitative trait loci (QTL) associated with FHB resistance.

Follicle curetting at the time of oocyte retrieval increases the oocyte yield.

Purpose: To determine whether follicle curetting at the time of oocyte retrieval increases oocyte yield.

Methods: Retrospective review of all patients who underwent oocyte retrieval from July 1, 2003 to June 30, 2005.

Main Outcome Measure: Number of oocytes retrieved.

Dynorphin immunoreactive fibers contact GnRH neurons in the human hypothalamus.

Dynorphin, an endogenous opioid peptide, mediates progesterone-negative feedback on gonadotropin-releasing hormone (GnRH) neurons in other species. The role of dynorphin in humans is unclear. The objective of this study was to determine if dynorphin fibers have close contacts with GnRH neurons in humans.

Maternal virilization due to luteoma associated with delayed lactation.

Objective: To report on a patient with virilization during pregnancy who experienced delayed lactation secondary to elevated maternal androgens.

Design: Case report and review of the literature.

Setting: University hospital.
