Hair Texture Gene Discovered

Monday, March 3rd, 2008

(Ivanhoe Newswire) — The next time you have a bad hair day, think twice before you point fingers at the weather … your genes may be to blame!

Researchers at Columbia University Medical Center have uncovered a gene involved in determining hair texture in humans. Mutations in the P2RY5 gene cause hereditary “wooly” hair — hair that is coarse, dry, tightly curled and sparse.

Since wooly hair is most commonly found in Pakistani families, researchers performed a genetic analysis of six families of Pakistani origin with hereditary wooly hair. The mutated P2RY5 gene was clearly found mutated and deemed the cause for the family’s hair texture.

Robotic Surgery for Cancer Involving Tonsils Shows Promise

Wednesday, December 19th, 2007

(Ivanhoe Newswire) — A surgical technique using robotic arms is offering hope to cancer patients who need radical tonsillectomies. The new procedure is called transoral robotic surgery (TORS) and, after evaluation over a 2-year period at the University of Pennsylvania, it appears to be a significant improvement over the current procedure.

Right now, surgeons have limited access to the tonsils. And if the cancer has spread to surrounding tissue, the procedure involves cutting through skin. It can be a lengthy surgery often followed by long-term difficulty in swallowing. It usually requires the placement of a tracheotomy tube.

Indoor Tanning Patterns Help Doctor’s Target Prevention

Wednesday, December 19th, 2007

(Ivanhoe Newswire) — Evidence that indoor tanning poses a serious skin cancer risk is rising. A new study helps doctors identify who’s doing the tanning and why so they can better target prevention messages. The study revealed that when it comes to indoor tanning, one size does not fit all.

Joel Hillhouse, Ph.D., at the East Tennessee State University, Johnson City and his colleagues studied the indoor tanning behaviors of 168 young women between January 2006 and April 2006. The average age of the participants was 20 and they all attended a southeastern university. They were all asked to fill out questionnaires to determine behavioral patterns, intentions, attitudes and perceptions abut indoor tanning. It also measured indoor tanning norms, perceived subjective norms and indoor tanning dependence and predictors.

12 Million New Cancer Cases Worldwide in 2007

Wednesday, December 19th, 2007

(Ivanhoe Newswire) – By the end of the year it is predicted there will be more than 12 million new cancer cases and 7.6 million cancer deaths worldwide – that’s about 20,000 cancer deaths a day.

The estimates come from a new American Cancer Society report based on data from the International Agency for Research on Cancer. The report also estimates 5.4 million of those cancers and 2.9 million deaths will be in economically developed countries, while 6.7 million case and 4.7 million deaths will be in economically developing countries.

The research shows the three most commonly diagnosed cancers in men in developed countries are prostate, lung, and colorectal cancer; in women they are breast, colorectal, and lung cancer. But in developing countries the three most commonly diagnosed cancers in men are lung, stomach, and liver cancer; and in women they are cancers of the breast, cervix uteri, and stomach. Cancers of the stomach, liver, and cervix are related to infection in these countries.

Granddaddy of All Blood Cells Identified

Monday, December 17th, 2007

(Ivanhoe Newswire) – The great-grandparent of all human blood cells has been identified. And if could lead to new treatments for blood cancers and other blood diseases.

Researchers from Stanford University School of Medicine isolated the cell - called the multipotent progenitor – which fills an important gap in the human blood cell family tree. It is the first offspring of the bone marrow stem cell.

The scientists isolated the human progenitor cell by grouping blood cells according to proteins on their surface. They then looked for a pool of cells that could form all the final cells of the blood but could not keep renewing their own supplies – a unique trait of stem cells. They found it and can now identify, isolate and study it in the lab.

Gene Linked to Aggressive Prostate Cancer

Thursday, December 13th, 2007

(Ivanhoe Newswire) – It is believed that there is a genetic component that predisposes some men to develop prostate cancer. Now, a new study identifies a gene that may be associated with aggressive prostate cancer.

Researchers at Wake University School of Medicine conducted the latest research along with investigators from Johns Hopkins Hospital. They looked at genetic changes to a single DNA base-pair that is known as SNPs (single nucleotide polymorphisms). Included in the research were 1,000 Swedish men with and without the disease. Then the SNPs that were most associated with prostate cancer underwent further study at Johns Hopkins Hospital.

Mammography Results Vary By Radiologist

Thursday, December 13th, 2007

(Ivanhoe Newswire) – Whether a diagnostic mammogram detects breast cancer accurately may depend on which radiologist reads it.

The ability to detect cancer accurately is known as sensitivity, and should be consistently high with few false-positives no matter which radiologist reads the mammogram. But new research from Group Men’s health Center for Men’s health Studies finds that is not the case.

The study looked at how well 123 radiologists from 72 facilities in the United States interpreted nearly 36,000 diagnostic mammograms which were done to evaluate breast problems such as lumps.

New Cancer Discovery, Hormone to Blame

Wednesday, December 12th, 2007

By Lindsay Braun, Ivanhoe Men’s health Correspondent

ORLANDO, Fla. (Ivanhoe Newswire) — A breakthrough discovery reveals one particular hormone is responsible for helping a cancer enzyme cause a type of deadly red blood cell cancer.

Thomas Bumm, M.D., lead researcher and member of the Oregon Men’s health & Science University Cancer Institute was working with the JAK2 cancer enzyme that is known to cause a blood thickening red blood cell cancer called polycythemia vera when he found that a specific hormone was actually fueling the JAK2 enzyme and causing the cancer to thrive.
