Vaccination most promising against asthma

Asthma is a chronic inflammatory and respiratory disease caused by an abnormal reactivity to allergens in the environment. Of the several avenues of exploration that are currently being developed, vaccination appears to be the most promising approach.

New NewYork-Presbyterian autism center to open in early 2013

NewYork-Presbyterian Hospital, along with its affiliated medical schools Weill Cornell Medical College and Columbia University College of Physicians and Surgeons, today celebrated the start of construction on the new Center for Autism and the Developing Brain at the Hospital's Westchester campus in White Plains.

Only few women consume aspirin to reduce risk of heart disease

Heart disease is the leading cause of death among women, and evidence-based national guidelines promote the use of daily aspirin for women at increased risk for cardiovascular disease. However, less than half of the women who could benefit from aspirin are taking it, according to an article in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc.

IntegraGen’s ARISk Test looks at 65 genetic markers associated with autism

IntegraGen, Inc., a biotechnology company dedicated to molecular biomarker discovery, today announced the launch of the ARISk- Risk Assessment Test, a gender specific, genetic screening test that looks at 65 genetic markers associated with Autism Spectrum Disorder.

UV light-activated on-off switch for Morpholinos

University of Oregon scientists collaborating with an Oregon company that synthesizes antisense Morpholinos for genetic research have developed a UV light-activated on-off switch for the vital gene-blocking molecule. Based on initial testing in zebra-fish embryos, the enhanced molecule promises to deliver new insights for developmental biologists and brain researchers.

CHD8, SNC2A and KATNAL2 gene mutations lead to ASDs

Mutations in three new genes have been linked to autism, according to new studies including one with investigators at Mount Sinai School of Medicine. All three studies include lead investigators of the Autism Sequencing Consortium.

Fathers more likely to transmit spontaneous mutations to children with ASDs

Researchers have turned up a new clue to the workings of a possible environmental factor in autism spectrum disorders (ASDs): fathers were four times more likely than mothers to transmit tiny, spontaneous mutations to their children with the disorders. Moreover, the number of such transmitted genetic glitches increased with paternal age. The discovery may help to explain earlier evidence linking autism risk to older fathers.

More than 4 in 10 people at high risk for hereditary pancreatic cancer have small lesions

A team of scientists led by Johns Hopkins researchers have found that more than four in 10 people considered at high risk for hereditary pancreatic cancer have small pancreatic lesions long before they have any symptoms of the deadly disease.

Olanzapine improves survival in mouse model of anorexia nervosa

Low doses of a commonly used atypical antipsychotic drug improved survival in a mouse model of anorexia nervosa, University of Chicago researchers report this month. The result offers promise for a common and occasionally fatal eating disorder that currently lacks approved drugs for treatment.

New SORL1 gene causes early-onset Alzheimer's

A new gene that causes early-onset of Alzheimer's disease has been discovered by the research team of Dominique Campion at the Insert unit 1079 "Genetics of cancer and neuropsychiatric diseases" in Rouen.

Getting pregnant while on a diet may lead to an obese baby: Study

Researchers found in a study on sheep that giving ewes less food at the time of conception caused DNA changes in the brains of their young. The University of Manchester scientists suspect the findings may hold true for humans as well and could explain why twins are more likely to develop Type 2 diabetes in adulthood.

Bare platinum coils vs. newer gel-coated coils for aneurysm treatment

Approximately 6 million Americans have brain aneurysms, a condition that occurs when a weak or thin spot develops on a blood vessel in the brain causing it to balloon. Often, these do not cause symptoms and go undetected, but every year an estimated 30,000 Americans experience a ruptured aneurysm that bleeds into the brain causing a life threatening injury.

Reactivation of p53 may be a highly selective treatment modality for virally-induced lymphoma

Kaposi's sarcoma herpesvirus (KSHV) is a human tumor virus and an etiological agent for Kaposi's sarcoma and primary effusion lymphoma (PEL). PELs are aggressive lymphomas with reported median survival time shorter than six months after diagnosis.

Drugs that target cholesterol pathway may enhance cancer-killing potential of chemotherapy drugs

Johns Hopkins investigators are testing a way to use drugs that target a cholesterol pathway to enhance the cancer-killing potential of standard chemotherapy drugs. Their tests, in mouse models of pancreatic cancer, may yield new and more effective combinations of current and possibly new anti-cancer drugs.

Impact of Personal Genomics Study to launch data collection phase

As genetic risk information plays an increasingly important role in the diagnosis and treatment of many diseases, private companies have made personal genomic testing for these risk factors widely available to the public. However, very little data has been gathered to understand the motivations and expectations of consumers of personal genomic services, the psychological and behavioral impact of these services, and the associated ethical, legal and social issues—until now.

Causes of traumatic brain injury in older population

As the population ages in western countries, traumatic brain injury (TBI) resulting mainly from falls is on the rise among the elderly, introducing new complications and treatment challenges, according to an article in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc.

Preterm or post-term babies with autism more likely to self-injure

For children with autism, being born several weeks early or several weeks late tends to increase the severity of their symptoms, according to new research out of Michigan State University.

Hepatitis B-infected patients with longer telomeres more likely to develop HCC

Hepatitis B-infected patients with significantly longer telomeres—the caps on the end of chromosomes that protect our genetic data— were found to have an increased risk of getting liver cancer compared to those with shorter ones, according to findings presented by researchers at Jefferson's Kimmel Cancer Center at the American Association for Cancer Research (AACR) Annual Meeting 2012.

Gbb38 protein helps explain how cells send many long-haul messages

As they work together to form body parts, cells in developing organisms communicate like workers at a construction site. The discovery of a new signaling molecule in flies by Brown University biologists not only helps explain how cells send many long-haul messages, but also provides new clues for researchers who study how human development goes awry, for instance in cases of cleft lip and palate.

Genomic fortune-telling fails to provide informative guidance to most people

With sharp declines in the cost of whole genome sequencing, the day of accurately deciphering disease risk based on an individual's genome may seem at hand. But a study involving data of thousands of identical twins by Johns Hopkins investigators finds that genomic fortune-telling fails to provide informative guidance to most people about their risk for most common diseases, and warns against complacency born of negative genome test results.
