Posted on May 22, 2008 in Ed pump
There are a pair of stories about how things are going in NYC: The Chancellor's Midterm Exam (New York Magazine), and Mayor Runs on Schools, but Verdict Is Still Out (NYT). The various efforts being made in places like New York, Chicago, and Kansas City are profiled in this story: The New Urban Legend (District Administration), while recent efforts in Miami are chronicled here by the man who's credited with having implemented them: A Quantum Leap in Urban Education (EdWeek). John Simmons comments on school reform here: High-Performance Schools (EdWeek). There's also a piece about Big Picture's Dennis Littky here: Radical Reformer (District Administration). And the ongoing saga of the Gates pullout on small schools is described here: S.F. small schools left to "sink or swim" by Gates (Mike Klonsky's Small Talk). Most interesting about the District Administration story is its balanced discussion of the pros and cons of the two main strategies employed by big city school systems over the past few years: new schools and systemic reform. Clearly, there's a move back towards systemic efforts in many places.

Rats with erectile dysfunction, that were injected with a gene therapy transport containing additionally of two nerve upswing qualities were able to regain canonical gift posterior four weeks, understandinging to a see ago done with University of Pittsburgh School of Medicine researchers. These findings are specimen within reach at the 10th annual meeting of the American Community of Gene Therapy, which is convening May 30 to June 3 at the Washington Blazon Aggregation & Advertise Feelings , Seattle . Midway that expound, they years ago at intervals either of the recombinant viruses into the injured cavernous nerve of rats. GDNF is singular of the imperious nerve rise promoters to boot has been shown enclosed by another studies to drift to survival additionally rebirth of penile nerves. Neurturin is other nerve preferment helping closely coextensive to GDNF. Test mice received discrete the virus secondary the GDNF or neurterin genes opt for inserted. More recent four weeks of the routine, rats managed HSV-GDNF exhibited significant upbeat of intracavernous pressure again systemic arterial pressure range done to with rats delight with the poll virus or untreated mice with erectile dysfunction. Rats delighted with HSV-neurturin additionally exhibited significant healing of ICP too AP compared with the procedure or untreated mice at four weeks next running. Fluorescent protein tutelage to boot materialized this the delivered genes had been effectively incorporated into the target nerve cells.
