On Becoming a District of Choice: Implications for Equity Along the United States-Mexico Border.

Purpose: Despite the popularity of open enrollment as a school choice mechanism, there is little research on how principals behave in a district-run competitive setting. This study adds to our understanding of how open enrollment policies affect the role of the principal as well as educational equity by examining the roles and behaviors of school principals in an unregulated marketplace of schools.

Research Method: This study uses an explanatory sequential mixed methods approach.

Trends in Acute Primary Angle-Closure Glaucoma, Peripheral Iridotomy and Cataract Surgery in Scotland, 1998-2012.

Purpose: We present rates of acute primary angle-closure glaucoma (APACG), peripheral iridotomy (PI) and cataract surgery in Scotland between 1998 and 2012.

Methods: The number of patients in Scotland with APACG in each of the years between 1998 and 2012 was obtained from Information Service Division (ISD) Scotland. Data was also obtained for patients who had undergone laser PI and cataract surgery.

Expansive gene transfer in the rat CNS rapidly produces amyotrophic lateral sclerosis relevant sequelae when TDP-43 is overexpressed.

Improved spread of transduction in the central nervous system (CNS) was achieved from intravenous administration of adeno-associated virus serotype-9 (AAV9) to neonatal rats. Spinal lower motor neuron transduction efficiency was estimated to be 78% using the highest vector dose tested at a 12-week interval. The widespread expression could aid studying diseases that affect both the spinal cord and brain, such as amyotrophic lateral sclerosis (ALS).

In vivo survivors of transformed mouse ovarian surface epithelial cells display diverse phenotypes for gene expression and tumorigenicity.

Ovarian cancer is the fifth most common cause of cancer death in women. Due to a lack of appropriate animal models, studies involving tumorigenicity, tumor progression and immune response at the molecular level are limited. We isolated many clones derived from thesurvivors of a transformed mouse ovarian epithelial cell line IG-10 in immune- competent mice and found that the clones displayed diverse phenotypes.
