Brain imaging can offer a window into risk for diseases such as Alzheimer's disease (AD). A study conducted at the University of Kansas School of Medicine demonstrated that genetic risk is expressed in the brains of even those who are healthy, but carry some risk for AD. The results of this study are published in the November 2009 issue of the Journal of Alzheimer's Disease. http://www.physorg.com/news177690665.html Medicine & Health Tue, 17 Nov 2009 14:31:29 EST news177690665 (PhysOrg.com) -- The gnawing pain of rheumatoid arthritis is a signal that the body`s immune system has hit the wrong target: its own cartilage and bone. http://www.physorg.com/news176978059.html Medicine & Health Mon, 09 Nov 2009 08:35:22 EST news176978059 Immune therapies have been explored as a way to treat cancer after it develops. But a new study from the University of Michigan Comprehensive Cancer Center suggests that genetic risk of prostate cancer can be reduced by rescuing critical immune system cells. http://www.physorg.com/news172918535.html Medicine & Health Wed, 23 Sep 2009 09:55:51 EST news172918535 An international team of scientists has identified two more genetic risk factors for Alzheimer's disease. The findings are reported in the online edition of the journal Nature Genetics. http://www.physorg.com/news171461698.html Medicine & Health Sun, 06 Sep 2009 13:17:05 EST news171461698 Researchers have pinpointed a specific gene variation that causes increased risk of urinary bladder cancer, according to a scientific team led by The University of Texas M.

Anderson Cancer Center. http://www.physorg.com/news168439858.html Medicine & Health Sun, 02 Aug 2009 13:52:13 EST news168439858 (PhysOrg.com) -- Research by a group of Montreal scientists calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell. Their results appear in the July issue of the journal Human Mutation. http://www.physorg.com/news166882585.html Medicine & Health Wed, 15 Jul 2009 13:30:01 EST news166882585 With just $399 and a bit of saliva in a cup, consumers can learn about their genetic risk for diseases from breast cancer to diabetes. Now, thanks to social networking sites set up by personal genomics companies, they can also share that information with family, friends and even strangers on the Internet. http://www.physorg.com/news163394275.html Medicine & Health Fri, 05 Jun 2009 04:18:36 EST news163394275 Researchers at the University of Pennsylvania School of Medicine have uncovered variation around two genes that are associated with an increased risk of testicular cancer. Testicular cancer is the most common cancer among young men, and its incidence among non-Hispanic Caucasian men has doubled in the last 40 years -- it now affects seven out of 100,000 white men in the United States each year. The discovery, published in the May 31, 2009 online issue of Nature Genetics, is the first step toward understanding which men are at high risk of disease. http://www.physorg.com/news162995399.html Medicine & Health Sun, 31 May 2009 13:30:32 EST news162995399 A family-based prevention program designed to help adolescents avoid substance use and other risky behavior proved especially effective for a group of young teens with a genetic risk factor contributing toward such behavior, according to a new study by researchers at the University of Georgia. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) and the National Institute on Drug Abuse (NIDA), components of the National Institutes of Health, supported the study, which appears in the May/June issue of Child Development. http://www.physorg.com/news161614455.html Medicine & Health Fri, 15 May 2009 13:55:06 EST news161614455 UCLA scientists, in partnership with 30 research institutions across the country, have identified a new gene variant that is highly common in autistic children. And when researchers scrutinized the activity of the gene, known as CDH10, in the fetal brain, they discovered that it is most active in key regions that support language, speech and interpreting social behavior. http://www.physorg.com/news160145737.html Medicine & Health Tue, 28 Apr 2009 13:56:02 EST news160145737 During the past few years, several new genetic risk factors for rheumatoid arthritis (RA) have been identified. The majority of genetic risk factors identified so far have been associated with autoantibody-positive RA, which affects about two-thirds of RA patients, but distinguishing this variant from autoantibody-negative RA, which is less destructive, is considered increasingly important. http://www.physorg.com/news158327861.html Medicine & Health Tue, 07 Apr 2009 12:58:15 EST news158327861 Children and siblings of those with venous thrombosis, or blood clots in the veins, appear to have more than double the risk of developing the condition than those without a family history, according to a report in the March 23 issue of Archives of Internal Medicine. http://www.physorg.com/news157044991.html Medicine & Health Mon, 23 Mar 2009 16:37:00 EST news157044991 A test capable of confirming or ruling out Alzheimer's disease has been validated and standardized by researchers at the University of Pennsylvania School of Medicine. By measuring cerebrospinal fluid (CSF) concentrations of two of the disease's biochemical hallmarks - amyloid beta42 peptide and tau protein - the test also predicted whether a person's mild cognitive impairment would convert to Alzheimer's disease over time. Researchers were able to detect this devastating disease at the earliest stages, before dementia symptoms appeared and widespread irreversible damage occurred. The findings hold promise in the search for effective pharmaceutical therapies capable of halting the disease. http://www.physorg.com/news156435142.html Medicine & Health Mon, 16 Mar 2009 15:13:05 EST news156435142 A new analysis has found that certain variations in genes that repair DNA can affect a person's risk of developing Hodgkin disease. Published in the April 1, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study indicates that differences in these genes should be further investigated to better understand individuals' susceptibility to this type of cancer. http://www.physorg.com/news155810660.html Medicine & Health Mon, 09 Mar 2009 09:44:59 EST news155810660 A history of major depression increases the risk of heart disease over and above any genetic risks common to depression and heart disease, according to researchers at Washington University School of Medicine in St. Louis and the VA.

In research published this month in BMC Medical Genetics, scientists from The Rockefeller University and colleagues from the University of Oxford in England and the University of British Columbia in Canada report a binding pocket in a previously implicated gene that may be an attractive research prospect as a potential drug target. http://www.physorg.com/news153592039.html Medicine & Health Wed, 11 Feb 2009 16:27:55 EST news153592039 A genetic risk factor that increases the likelihood that youth will engage in substance use can be neutralized by high levels of involved and supportive parenting, according to a new University of Georgia study. http://www.physorg.com/news153501501.html Medicine & Health Tue, 10 Feb 2009 15:18:44 EST news153501501 We may be a long way off from using genetics to reliably gauge our risks for specific diseases, say researchers at the University of Pittsburgh Graduate School of Public Health in a study published on Feb. 5 in the online journal PLoS Genetics. Yet, many companies currently offer personalized genetic testing for diseases like cancer, heart disease and diabetes, and tout the ability of DNA testing to predict future health risks. http://www.physorg.com/news153145607.html Medicine & Health Fri, 06 Feb 2009 12:27:26 EST news153145607 Men with a family history of prostate cancer and African-American men are particularly susceptible to the disease, with a twofold to sevenfold increased risk. Assessing risk in these populations has been difficult. http://www.physorg.com/news146146235.html Medicine & Health Mon, 17 Nov 2008 12:10:35 EST news146146235
