Neuroscientists use snail research to help explain ‘chemo brain’

In an effort to solve this mystery, neuroscientists at The University of Texas Health Science Center at Houston (UTHealth) conducted an experiment in an animal memory model and their results point to a possible explanation. Findings appeared in The Journal of Neuroscience. In the study involving a sea snail that shares many of the same memory mechanisms as humans and a drug used to treat a variety of cancers, the scientists identified memory mechanisms blocked by the drug. …

Gene can predict aggressive prostate cancer at diagnosis — ScienceDaily

The results reported in the journal of Clinical Cancer Research, a publication of the American Association of Cancer Research, indicate the KLK3 gene — a gene on chromosome 19 responsible for encoding the prostate-specific antigen (PSA) — is not only associated with prostate cancer aggression, but a single nucleotide polymorphism (SNP) on it is more apparent in cancer patients with GS7. Researchers have linked Gleason score, an important predictor of prostate cancer outcomes, to several clinical end points, including clinical stage, cancer aggression and survival. …

Many women receive unnecessary pap tests

Performing these unnecessary tests can result in stress for the patient, increased costs, and inefficient use of both provider and patient time, concludes a new study in the American Journal of Preventive Medicine. “During this time of health care reform, we could probably use our resources more wisely,” said corresponding author Deanna Kepka, Ph.D., M.P.H., assistant professor at the University of Utah’s College of Nursing and Huntsman Cancer Institute.”Other conditions and screenings should probably merit the attention of primary care providers, including obesity and cancer,” she said, “especially in light of the newer 2012 cancer screening guidelines.” Kepka and her co-authors, who performed the study while at the National Cancer Institute, analyzed data from the 2010 National Health Interview Survey (NHIS) of women ages 30 and older…

Gene can predict aggressive prostate cancer at diagnosis

The results reported in the journal of Clinical Cancer Research, a publication of the American Association of Cancer Research, indicate the KLK3 gene — a gene on chromosome 19 responsible for encoding the prostate-specific antigen (PSA) — is not only associated with prostate cancer aggression, but a single nucleotide polymorphism (SNP) on it is more apparent in cancer patients with GS7. Researchers have linked Gleason score, an important predictor of prostate cancer outcomes, to several clinical end points, including clinical stage, cancer aggression and survival. There has been much research associated with prostate cancer outcomes as well as GS7 prostate cancers, which is an intermediate grade of cancer accounting for 30 to 40 percent of all prostate cancers. “This is the first report that I am aware of that indicates a genetic variant can stratify GS7 prostate cancer patients,” said Jian Gu, Ph.D., associate professor at MD Anderson, and a key investigator on the study. …

Minority background, low education, and low income negatively influence HPV vaccine series completion

To better understand why women who initiate HPV vaccination do not complete the series, a team of researchers led by Dr. Abbey Berenson from the University of Texas Medical Branch examined the correlates of vaccine series completion among young women using data from the Behavioral Risk Factor Surveillance System (BRFSS), a cross-sectional telephone health survey conducted by the Centers for Disease Control and Prevention. …

Immune system is key ally in cyberwar against cancer

“Recent research has found that cancer is already adept at using cyberwarfare against the immune system, and we studied the interplay between cancer and the immune system to see how we might turn the tables on cancer,” said Rice University’s Eshel Ben-Jacob, co-author of a new study this week in the Early Edition of the Proceedings of the National Academy of Sciences. Ben-Jacob and colleagues at Rice’s Center for Theoretical Biological Physics (CTBP) and the University of Texas MD Anderson Cancer Center, developed a computer program that modeled a specific channel of cell-to-cell communication involving exosomes. Exosomes are tiny packets of proteins, messenger RNA and other information-coding segments that both cancer and immune cells make and use to send information to other cells…

Cancer cells adapt energy needs to spread illness to other organs

Ancient Greek warriors were fed a special diet that better prepared them for the demands of battle on distant fields. Cancer cells that metastasize may do the same thing according to a new study revealing previously unknown differences between cancer cells that continue to grow at the original tumor site, and those that travel to other organs. Given that a cancer cell’s unyielding ability to metastasize is the primary cause of cancer-related death, understanding how they successfully migrate can be lifesaving…

UT Southwestern one of two institutions to offer innovative four-flap microsurgery approach to breast reconstruction

The technique, known as a four-flap breast reconstruction, uses fat and skin from the back of each leg and from two spots on the stomach to reconstruct natural breast materials. “It reaches a new height in breast reconstructive surgery, using your own tissue,” said Dr. Sumeet Teotia, Assistant Professor of Plastic Surgery, who performs the procedure along with Dr. …
