Spinal cord injury (SCI) induces the disruption of the blood-spinal cord barrier (BSCB), which leads to infiltration of blood cells, inflammatory responses and neuronal cell death, with subsequent development of spinal cord secondary damage. Recent reports pointed to an important role of retinoic acid (RA), the active metabolite of the vitamin A, in the(More)
After spinal cord injury (SCI), disruption of blood-spinal cord barrier (BSCB) elicits blood cell infiltration such as neutrophils and macrophages, contributing to permanent neurological disability. Previous studies show that epidermal growth factor (EGF) produces potent neuroprotective effects in SCI models. However, little is known that whether EGF(More)
Over the last decade, the number of one-to-one laptop programs in U.S. schools has steadily increased. Though technology advocates believe that such programs can assist student writing, there has been little systematic evidence for this claim, and even less focused on technology use by at-risk learners. This study examined the effect of daily access to(More)
Spinal cord injury (SCI) induces the disruption of the blood-spinal cord barrier (BSCB) which leads to infiltration of blood cells, an inflammatory response, and neuronal cell death, resulting spinal cord secondary damage. Retinoic acid (RA) has a neuroprotective effect in both ischemic brain injury and SCI, however the relationship between BSCB disruption(More)
For the last seven years, our team has been investigating learning and literacy practices in K–12 classrooms across the United States where all the students have laptop computers. We have found that the greatest impact of individual laptop use is on student writing. When students have daily access to Internet-connected laptops, they conduct more background(More)
In planning educational technology initiatives, the concerns of many stakeholders are typically taken into account, including the concerns of administrators, teachers, parents, and employers. The perspective of students are recognized as valuable, but not often queried or considered. This paper explores the opinions of K-12 students about a one-to-one(More)
