Senior Focus: Testosterone treatment questions

Posted: Published on May 8th, 2014

Testosterone use among men has increased significantly in recent years. Much of this increase is in response to doctors recommendations for treatment of symptomatic low testosterone levels, advertising of testosterone replacement therapy and the belief that low testosterone may increase the risk of developing cardiovascular disease (heart attack and stroke). Most recent studies that followed a population over time suggested that deficiencies in male hormones such as testosterone and dihydrotestosterone may increase the risk of cardiovascular disease. Because low testosterone is a potentially reversible condition, it makes some sense that hormone replacement would be a good idea to prevent cardiovascular disease. Additionally, higher testosterone levels among men in these observational studies was associated with a healthier cardiovascular risk profile, such as less diabetes, lower blood pressure, lower LDL cholesterol (bad cholesterol) and higher HDL cholesterol (good cholesterol). However, reality may tell a different story. We had long believed that hormone replacement therapy in women would protect against heart attacks and strokes. Estrogens help lower cholesterol and have other beneficial effects. However, it was not until a major study involving about 27,000 women chosen at random to receive hormone replacement therapy or a sugar pill that we learned that there was … Continue reading →

Few women at high-risk for hereditary breast and ovarian cancer receive genetic counseling

Posted: Published on May 8th, 2014

PUBLIC RELEASE DATE: 8-May-2014 Contact: John Wallace wallacej@vcu.edu 804-628-1550 Virginia Commonwealth University Mutations in the BRCA1 and BRCA2 genes account for nearly 25 percent of hereditary breast cancers and most hereditary ovarian cancers, yet a study by cancer prevention and control researchers at Virginia Commonwealth University Massey Cancer Center suggests an alarmingly small amount of women who qualify for BRCA genetic counseling actually receive the services. Additionally, they found that a significant proportion of women with a family history of breast and ovarian cancer underestimate their own risk. The study, published in the April edition of the Journal of Community Genetics, collected data from 486 women over the course of two years. Of these women, 22 met the criteria to be referred for BRCA counseling. However, only one of the women reported receiving genetic counseling and only one reported prior genetic testing. And while perceived risk of developing breast and ovarian cancer was higher among high-risk women, 27 percent of high-risk women felt their risk was "low," and 32 percent felt their risk was "lower than average." Despite having a diverse population, the researchers did not find any significant differences associated with factors such as age, race, family size or … Continue reading →

Cell Biologists’ Top Scientific Honor Goes to Pioneers of the Cytoskeleton

Posted: Published on May 8th, 2014

Contact Information Available for logged-in reporters only Newswise BETHESDA, MD, MAY 7, 2014If cells were cars, then the three pioneering cell biologists just named winners of the 2014 E.B. Wilson Medal, the highest scientific honor of the American Society for Cell Biology, helped write the essential parts list. William Bill Brinkley of the Baylor College of Medicine in Houston, John Heuser of the Washington University School of Medicine in St. Louis, and Peter Satir of the Albert Einstein College of Medicine in the Bronx identified crucial pieces of the cytoskeleton, the cells shape-shifting framework, and showed how these elements drive life at the cellular level. Named for Edmund Beecher Wilson (1856-1939), Americas first modern cell biologist, the Wilson Medal will be presented to the winners in December at the ASCBs 54th Annual Meeting in Philadelphia. We selected these three people because of their lifetime contributions to the field of cell biology, particularly to the study of the cytoskeleton, says Joseph Gall, of the Carnegie Institution of Washington, who chaired the Wilson Medal selection committee for ASCB. The E.B. Wilson is the highest award given by the ASCB and it means a great deal to ASCB members, who recognize that our … Continue reading →

Humans and Their Pet Dogs: Shared Cancers, Shared Hope in Dr. Matthew Breen’s Research Featured at 2014 ACVIM Forum …

Posted: Published on May 8th, 2014

Contact Information Available for logged-in reporters only Newswise (Denver, Colo.) In human medicine a gold standard of diagnosis and prognosis for numerous cancers has involved cytogenetic (linking the study of genetic inheritance with the study of cell structure) assessment of the tumor cells. Within the past few years scientists have demonstrated that characteristic cytogenetic changes associated with human cancers are shared in corresponding canine cancers. Researchers are now exploring the broader use of cytogenetics in veterinary oncology as a means to advance clinical management and treatment options for cancers affecting pet dogs. To pursue this first required the development of key reagents and tools specific for use with canine specimens, says Dr. Matthew Breen, a North Carolina State University College of Veterinary Medicine professor of genomics. Breen will address the 2014 ACVIM Forum attendees Wednesday, June 4 from 10:0511:45 a.m. at the Gaylord Opryland Resort & Convention Center in Nashville with presentations titled, Genomics & Genetics in Veterinary Medicine: An Overview and Cancer in the Domestic Dog: A Genome With Two Tales, detailing the latest advances in the field. Breens laboratory has developed an extensive cytogenetics toolbox designed to provide the necessary means to identify key cytogenetic signatures in numerous … Continue reading →

By Kate WeidawUpdated: Thursday, May 8, 2014, 5:49 amPublished: Thursday, May 8, 2014, 5:36 am AUSTIN (KXAN) In spite of the pending rain, Thursday is an opportunity to help someone fighting cancer beat it. Its being called Swab Fest. and its an effort to get more people to sign up to be stem cell donors on the national registry. The festival was organized to try and find a match for Austinite Brady Oman, 61, who found out he had leukemia at the beginning of the year. He is on his fourth round of chemo and in desperate need of a stem cell transplant, said Susan Wise, Brady Omans partner. Before Oman ended up at MD Anderson battling leukemia he thought in January a bad cold wouldnt go away. Within days he ended up at the hospital thinking it was a heart attack because he couldnt breathe or see well. They said good news you didnt have a heart attack, bad news normal high for white blood cell is 10,000 and yours is 190,000 you have leukemia and it was all in one sentence, said Wise. So far the chemo has saved his life but the clock is ticking and he … Continue reading →

Japan institute rejects 'phoney' research scientist appeal

Posted: Published on May 8th, 2014

TOKYO: A respected Japanese institute that sponsored stem cell research hailed as groundbreaking said Thursday the young scientist who wrote the paper should withdraw it, adding it stood by its conclusion that she fabricated data. Haruko Obokata, 30, has insisted her findings were accurate, saying she had managed to create the building-block cells capable of growing into the specialised cells of the brain, liver, heart or kidneys. She had urged her employer to reconsider its findings and exonerate her, but on Thursday the Riken Institute rejected that appeal in a move that may -- in the worst case scenario -- lead to a disciplinary discharge. "The institute has decided not to review the conclusion and informed the person concerned of the decision as of today, while advising (her) to withdraw the paper," it said in a statement. Obokata was feted as a modern-day Marie Curie after unveiling research that showed a simple way to re-programme adult cells to become a kind of stem cell. So-called Stimulus-Triggered Acquisition of Pluripotency (STAP) cells were hailed as a breakthrough that could provide a ready supply of the base material for much-needed transplant tissue, at minimal cost. But within weeks of her paper being … Continue reading →

Service dog receives cutting-edge stem cell therapy

Posted: Published on May 8th, 2014

A service dog that has come from the brink of death and back was in Terry on Wednesday to receive cutting-edge stem cell therapy. Davis Hawn said his dog, Booster, saved his life and now he's working to return the favor. "With Booster by my side, I greet each day knowing we can change the world for the better," Hawn said. Together, Hawn and Booster helped foster international relations by appearing on TV in Cuba. They reassured Thai orphans infected with the HIV virus that life will be OK and they are loved. The list of accomplishments continued to grow until Booster developed hip dysplasia. "When Booster couldn't get off the floor, I couldn't get out of bed," said Hawn, who suffers from depression. "Just as assuredly as God put Booster into my life, He again answered the call when I read about the modern day marvel of stem-cell implantation." Medivet America, a global leader in veterinary science with more than 1,000 clinics in 28 countries, learned of Booster's plight and jumped in to help. "They arranged to perform a procedure in which they injected Booster's own stem cells into his hips and got him back up and running again," … Continue reading →
