Group Files Petition Over Enforcement Of Regulations In Adult Film Industry To Prevent Sexually Transmitted Diseases
The AIDS Healthcare Foundation last week filed a petition in Los Angeles County Superior Court asking "the court to order the Los Angeles County Department of Public Health to enforce regulations that require condom use in adult-film production or take other reasonable steps to stem the spread of disease," the Los Angeles Times reports (Yoshino, 7/17). In the petition, "the group claims that in the month since an actress tested positive for HIV, the county Department of Public Health has done little to address what it considers to be a serious health threat" (AP/San Jose Mercury News, 7/16). In a statement released last week, the department, said, "The county continues to strongly support state legislation and the regulatory role of the [California Division of Occupational Safety and Health] as the most appropriate means to regulate the practices in the adult-film industry that expose performers to unnecessary and preventable occupational risks of acquiring and transmitting these diseases," adding, "The department does not believe that litigation is the best means to deal with this issue" (Yoshino, 7/17).

Cholesterol-Regulating Genes Identified By Scientists
Scientists at the European Molecular Biology Laboratory (EMBL) and the University of Heidelberg, Germany, have come a step closer to understanding how cholesterol levels are regulated. In a study published in the journal Cell Metabolism, the researchers identified 20 genes that are involved in this process. Besides giving scientists a better idea of where to look to uncover the mechanisms that ensure cholesterol balance is maintained, the discovery could lead to new treatments for cholesterol-related diseases.

Researchers Uncover Proteins Underlying Devastating Brain Diseases
Scientists at the Wellcome Trust Sanger Institute have discovered a set of brain proteins responsible for some of the most common and devastating brain diseases. The proteins underlie epilepsy, depression, schizophrenia, bipolar disease, mental retardation and neurodegenerative diseases including Alzheimer"s and Huntington"s diseases.

International Stem Cell Collaboration Results In Discovery Of Promising New Stem Cell Type

DaVinci Biosciences LLC in collaboration with University of Utah, Southern California Center for Regenerative Medicine and Omni Hospital in Ecuador, announce the discovery of a previously unidentified stem cell population from adult human testis in Biochemical and Biophysical Research Communications (BBRC), an international peer-reviewed journal focused on the rapid dissemination of timely and significant experimental results in diverse fields of biological research. Termed gonadal stem cells (GSCs) these adult derived stem cells, unlike previous reported population of stem cells found within the testis, have been found to demonstrate adult stem cell properties. Published in the current journal of Biochemical and Biophysical Research Communications, the data from this collaborative study describes a multipotent adult stem cell population that has the capacity to readily differentiate into multiple cell types. The study evolved from an international collaboration aimed at identifying novel cell populations at different geographical laboratory locations and for different HLA types. "We began this study purely as an approach to study and identify novel cell types and mechanisms regulating the role of infertility," said Francisco Silva, President of DaVinci Biosciences. "We were surprised and delighted to find a cell population that demonstrated these stem cell properties." Dr. Amit Patel, Director of Cardiovascular and Regenerative Medicine for the University of Utah School of Medicine and senior author of the study is currently collaborating with DaVinci Biosciences to study the genetic diversity of different cell populations and their role in personalized medicine. "We are establishing a database of genomic and cell characteristics that can eventually be correlated and placed into clinically translational therapeutic models that would ultimately help patients seeking to be treated with new pharmaceutical and cell-based therapies," said Dr. Patel. "In our attempt to expand cells from this tissue and study the genetics of the cell we found a population of cells that behaved like stem cells which could have therapeutic significance." The BBRC publication describes the cell population as having a high propensity to differentiate into chondrogenic and osteogenic cell types or cartilage and bone like cells, potentially leading to their use for orthopedic indications. Adult stem cells have been identified and described in various adult tissues to date and this published report is the first to identify an adult stem cell population from human testis with significant promise for new clinical applications.
