Background and Purpose— Cell death, especially apoptosis, occurred in brain tissues after subarachnoid hemorrhage (SAH). We examined the relationships between apoptosis disruption of blood–brain barrier (BBB), edema, mortality an established endovascular perforation model male Sprague-Dawley rats. Methods— A pan–caspase inhibitor (z-VAD-FMK) was administered intraperitoneally at 1 hour before 6 hours SAH. Expression caspase-3 positive TUNEL as markers for apoptosis. Results— Apoptosis mostly...
Within-study comparisons (WSCs) use real, rather than simulated, data to compare estimates from observational studies against a benchmark randomized controlled trial (RCT). A primary goal of WSCs is assess whether well-designed quasi-experimental designs (QEDs) can produce internally valid causal effect comparable those RCTs. In this paper, we describe the design and implementation new type WSC. Motivated by Shadish et al. (2008), examine impact mathematics training intervention vocabulary...
