Progranulin regulates neurogenesis in the developing vertebrate retina.

We evaluated the expression and function of the microglia-specific growth factor, Progranulin-a (Pgrn-a) during developmental neurogenesis in the embryonic retina of zebrafish. At 24 hpf pgrn-a is expressed throughout the forebrain, but by 48 hpf pgrn-a is exclusively expressed by microglia and/or microglial precursors within the brain and retina. Knockdown of Pgrn-a does not alter the onset of neurogenic programs or increase cell death, however, in its absence, neurogenesis is significantly delayed-retinal progenitors fail to exit the cell cycle at the appropriate developmental time and postmitotic cells do not acquire markers of terminal differentiation, and microglial precursors do not colonize the retina.

Technique of extraperitoneal uterosacral ligament suspension for apical suspension.

Aim Of The Video/introduction: Vaginal vault prolapse can occur alone or in combination with anterior or posterior compartment prolapse. Apical prolapse has shown a strong correlation with anterior wall prolapse and a moderate correlation with posterior wall prolapse. The McCall culdoplasty uses the extraperitoneal vaginal approach to support the vault at the time of hysterectomy.

Effects of melanin-concentrating hormone on licking microstructure and brief-access taste responses.

The effects of intracerebroventricular application of melanin-concentrating hormone (MCH) on licking for sucrose, quinine hydrochloride (QHCl), and water solutions were evaluated in two experiments. In experiment 1, rats received 90-min access to sucrose and water solutions after MCH or vehicle microinjection to the third ventricle (3V). MCH increased intake largely through increases in the rate of licking early in the meal and in the mean duration of lick bursts, suggesting an effect on gustatory evaluation.
