(Press-News.org) New Rochelle, NY, October 6, 2010—The introduction of a new, fully characterized viral vector for use as reference material to help standardize gene therapy protocols in research applications and human clinical trials is described in an article in Human Gene Therapy, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com). The article, which is published online ahead of print, is available free online at www.liebertpub.com/hum
The growing popularity in the gene therapy community of using recombinant adeno-associated virus (rAAV) vectors as vehicles to transfer a gene of interest into a host cell has led to increasing numbers of human clinical trials and animal studies with rAAV. In the past, the absence of standardization—such as for rAAV potency and dosing—have made it difficult for researchers and clinicians to compare their protocols and the results of gene therapy experiments. The availability of this rAAV reference standard will allow vector parameters to be expressed in common units, vector doses administered by different investigators to be normalized to an agreed-upon standard, and laboratories to calibrate their internal standards to a common reference material.
Martin Lock, from the Gene Therapy Program at the University of Pennsylvania (Philadelphia) and colleagues from several major medical and research institutions around the world, describe the development of reference standard in the article "Characterization of a Recombinant Adeno-Associated Virus Type 2 Reference Standard Material."
The American Type Culture Collection will make the rAAV2 reference standard material available to the scientific community. AAV serotype 2 was selected as the basis for the reference material because it is the best characterized AAV subtype. The material has been thoroughly analyzed and found to be free of microbial contamination. During development of the rAAV2 reference standard samples were distributed to 16 laboratories worldwide for extensive analysis and characterization.
"The development of a reference standard for an AAV vector is an important step towards the eventual commercial development of this important vector platform," says James M. Wilson, MD, PhD, Editor-in-Chief of Human Gene Therapy, and Head of the Gene Therapy Program, Department of Pathology and Laboratory Medicine, University of Pennsylvania School of Medicine, in Philadelphia.

Neighborhoods can have depressing effect on health, according to Iowa State study
2010-10-07
AMES, Iowa -- The nation's poverty rate climbed to 14.3 percent -- the highest level since 1994 -- according to the Census Bureau's annual report on the economic well-being of U.S. households. That means one in seven Americans now live in poverty, and that may have an especially depressing effect on people living in bad neighborhoods, according to two Iowa State University researchers.
Daniel Russell, an Iowa State professor of human development and family studies; and Carolyn Cutrona, professor and chair of psychology, presented "Stressful Effects of Where You Live: ...

Iowa State team calculates societal costs of five major crimes; finds murder at $17.25 million
2010-10-07
AMES, Iowa -- Murder takes an obvious toll on society in terms of the loss of human life, but what does it actually cost each time there's a murder? It's about $17.25 million according a recent Iowa State University study.
Matt DeLisi, an ISU associate professor of sociology and director of the criminal justice program, led a team of five Iowa State graduate students on the study of 654 convicted and incarcerated murderers. Expanding upon earlier monetization estimates, they calculated the costs of five crimes -- murder, rape, armed robbery, aggravated assault and burglary ...
Hormone acting as 'molecular glue' could boost plant immune systems
2010-10-07
EAST LANSING, Mich. — The discovery of a hormone acting like molecular glue could hold a key to bolstering plant immune systems and understanding how plants cope with environmental stress.
The study, which is featured in the Oct. 6 issue of Nature, reveals how the plant hormone jasmonate binds two proteins together – an emerging new concept in hormone biology and protein chemistry. The study also identifies the receptor's crystal structure to provide the first molecular view of how plants ward off attacks by insects and pathogens.
In short, the work explains how a highly ...
Patient-provider language barriers linked to worse diabetes control
2010-10-07
Patients who cannot discuss their diabetes with a doctor in their own language may have poorer health outcomes, even when interpreter services are available, according to a new study by researchers at UCSF and the Kaiser Permanente Division of Research.
The study found that, among Latino diabetes patients with limited English skills, those seen by non-Spanish speaking doctors were nearly twice as likely to have poor control of their blood sugar than those whose doctors spoke Spanish.
Findings will appear in the January 2011 issue of the Journal of General Internal ...
Vitamin D-ficiency common among orthopaedic surgery
2010-10-07
Forty-three percent of patients scheduled to undergo orthopaedic surgery have insufficient levels of vitamin D and two out of five of those patients had levels low enough to place them at risk for metabolic bone disease, according to a study published this month in the October 6th issue of the Journal of Bone and Joint Surgery (JBJS).
According to the National Institutes of Health (NIH) , vitamin D helps the body absorb calcium and is essential for bone growth and bone remodeling. Without sufficient vitamin D, bones can become thin, brittle or misshapen. People can obtain ...
Study provides data that can inform Atlantic sturgeon recovery efforts
2010-10-07
STONY BROOK, NY, October 6, 2010 - A first-of-its-kind study that tracked the oceanic migrations of adult Atlantic sturgeon that were caught and tagged in the Hudson River discovered that these fish move vast distances in the Atlantic Ocean, traveling as far south as Georgia and as far north as Nova Scotia, Canada. The findings indicate that recovery of Atlantic sturgeon fisheries will need to address long-range oceanic threats to the species in addition to local measures closer to spawning grounds. These results are particularly timely given the announcement on October ...
