  • Gene Linked to Alzheimer's May Affect Brain Early

    Posted: 07/22/2015

    Gene Linked to Alzheimer's May Affect Brain Early WEDNESDAY, July 15, 2015 (HealthDay News) -- Neurologists have long known that a variant of a gene called APOEe4 can raise the odds for Alzheimer's disease in people who carry it. Now, new research suggests that the gene is already affecting the brain years before the onset of the illness. Researchers at Indiana University in Indianapolis looked at 600 older adults, including some who said that they had significant memory problems even though they showed...

  • Genes May Be Key to a Better HIV Vaccine, Study Says

    Posted: 07/22/2015

    Genes May Be Key to a Better HIV Vaccine, Study Says WEDNESDAY, July 15, 2015 (HealthDay News) -- Someone's genetic makeup may determine whether an HIV vaccine will work, a new study suggests. Scientists say the finding could help them find a way to immunize people against HIV, the virus that causes AIDS. While researchers have reported advances over the years, a working vaccine still seems far off. Genetics are "almost certainly" relevant to how well vaccines work, but "vaccine designers have so far so...

  • Genetic Test May Help Spot Male Fertility Problems

    Posted: 07/15/2015

    Genetic Test May Help Spot Male Fertility Problems WEDNESDAY, July 8, 2015 (HealthDay News) -- A new genetic test for sperm could help determine whether a couple should resort to in vitro fertilization to conceive a child, researchers say. Men whose sperm lack critical RNA elements tend to have lower chances of naturally conceiving a child, according to study findings published July 8 in the journal Science Translational Medicine . An RNA analysis of a potential father's sperm can tell fertility doctors...

  • Good at Imagining Aromas? You May Be Prone to Weight Gain

    Posted: 07/14/2015

    Good at Imagining Aromas? You May Be Prone to Weight Gain TUESDAY, July 7, 2015 (HealthDay News) -- Your ability to imagine smells could affect your weight, researchers report. While everyone can imagine something such as a view from a favorite spot, the same is not true of odors, the researchers said. There is wide variation in people's ability to imagine the smell of pleasant things such as freshly baked bread or cookies, popcorn or a bouquet of roses, they explained. It's possible that the ability to...

  • Gene Therapy for Cystic Fibrosis Shows Some Promise in Study

    Posted: 07/09/2015

    Gene Therapy for Cystic Fibrosis Shows Some Promise in Study THURSDAY, July 2, 2015 (HealthDay News) -- Gene therapy for cystic fibrosis has for the first time shown slight but significant benefit on lung function, new British research reveals. In a randomized trial, patients inhaled molecules of DNA that aimed to replace the defective gene responsible for cystic fibrosis with a healthy, working copy of the gene in the lungs. "Patients who received the gene therapy showed a significant, if modest, benef...

  • Gene Mapping Yields Clues to Recent Ebola Outbreak

    Posted: 06/25/2015

    Gene Mapping Yields Clues to Recent Ebola Outbreak THURSDAY, June 18, 2015 (HealthDay News) -- New insight into the Ebola outbreak in West Africa has been gained by scientists who analyzed the genetic blueprint -- or genome -- of hundreds of specimens of the deadly virus. Health officials believe the worst of the epidemic that began in late 2013 is past, but the outbreak is not over. "Our early work tracked the virus's movements over just three weeks as the outbreak emerged in Sierra Leone. Now with a v...

  • Graphic Warnings May Work Best to Keep Women From Tanning Beds

    Posted: 06/18/2015

    Graphic Warnings May Work Best to Keep Women From Tanning Beds THURSDAY, June 11, 2015 (HealthDay News) -- Disturbing images of skin cancer are more likely to make young women reconsider indoor tanning than the text-only warnings currently required by U.S. regulators, a new study suggests. According to a team at Georgetown University Medical Center in Washington, D.C., nearly 30 percent of young, white women in the United States use indoor tanning each year, and half of them use indoor tanning 10 times ...

  • Germs in Foodborne Illness Gaining Resistance to Antibiotics, CDC Says

    Posted: 06/16/2015

    Germs in Foodborne Illness Gaining Resistance to Antibiotics, CDC Says TUESDAY, June 9, 2015 (HealthDay News) -- Antibiotic resistance in foodborne germs remains a public health threat despite attempts to combat the problem, according to new U.S. government data. Antibiotic-resistant infections from foodborne germs still cause about 440,000 illnesses in the United States each year, the U.S. Centers for Disease Control and Prevention reported online Tuesday. "Antibiotic resistance can arise spontaneously...

  • Gun Violence Takes Toll on Kids' Mental Health, Study Finds

    Posted: 06/16/2015

    Gun Violence Takes Toll on Kids' Mental Health, Study Finds MONDAY, June 8, 2015 (HealthDay News) -- More than one in four children in the United States is exposed to weapon-related violence -- as a victim or witness -- which ups their risk for mental health problems, a new study says. Using 2011 data from a national survey of children and parents, researchers also estimated that one in 33 kids has been assaulted in incidents where lethal weapons -- guns and knives -- were used. Such lethal weapons expo...

  • Genetic Differences Seen in Younger Colon Cancer Patients

    Posted: 06/10/2015

    Genetic Differences Seen in Younger Colon Cancer Patients TUESDAY, June 2, 2015 (HealthDay News) -- Colon cancer is genetically different in older and younger patients, and young adults may require different treatments, a new study suggests. While the overall rate of colon cancer in the United States is falling, the rate is rising among younger adults. And previous research has shown that colon cancer is more aggressive in patients younger than 50 than in older people, the researchers noted. In this stu...
