Study investigates possible links between maternal age and autism

In a study published in the May 2012 issue of the Journal of the American Academy of Child and Adolescent Psychiatry, led by Mr. Sven Sandin, of the Karolinska Institutet, Sweden and King's College London, researchers analyzed past studies to investigate possible associations between maternal age and autism. While much research has been done to identify potential genetic causes of autism, this analysis suggests that non-heritable and environmental factors may also play a role in children's risk for autism.

Researchers examines whether MRI can improve accuracy of Huntington’s diagnosis

Huntington disease (HD) is an inherited neurodegenerative disorder caused by a defect on chromosome four where, within the Huntingtin gene, a CAG repeat occurs too many times. Most individuals begin experiencing symptoms in their 40s or 50s, but studies have shown that significant brain atrophy occurs several years prior to an official HD diagnosis. As a result, the field has sought a preventive treatment that could be administered prior to the development of actual symptoms that might delay the onset of illness.

AAA to gather for anatomy meeting in conjunction with Experimental Biology 2012

The American Association of Anatomists will gather this week for its annual meeting in conjunction with the Experimental Biology 2012 conference, which will draw more than 14,000 scientists from industry, government and academia. Below are some programming highlights for the anatomy meeting. All presentations will be made at the San Diego Convention Center.

IMPAKT 2012 breast cancer conference to focus on four major areas

"Basic science and clinical medicine move at different pace because they follow different paths. Both however aim at improving strategies to manage cancer patients. We need to efficiently translate the good things from basic science and efficiently implement them in the clinic."

Fragile-X gene linked with disrupting de novo mutations in children with autism

A team led by scientists at Cold Spring Harbor Laboratory (CSHL) publishes research today indicating a striking association between genes found disrupted in children with autism and genes that are targets of FMRP, the protein generated by the gene FMR1, whose dysfunction causes Fragile-X syndrome.

Researchers identify new components of genetic pathway that controls neural stem cells

Can one feel too attached? Does one need to let go to mature? Neural stem cells have this problem, too. As immature cells, neural stem cells must stick together in a protected environment called a niche in order to divide so they can make all of the cells that populate the nervous system. But when it's time to mature, or differentiate, the neural stem cells must stop dividing, detach from their neighbors and migrate to where they are needed to form the circuits necessary for humans to think, feel and interact with the world.

U-M’s second human embryonic stem cell line now available for federally-funded research

The University of Michigan's second human embryonic stem cell line has just been placed on the U.S. National Institutes of Health's registry, making the cells available for federally-funded research. It is the second of the stem cell lines derived at U-M to be placed on the registry.

Robot assisted laparoscopic radical prostatectomy better than other surgical techniques

Outcomes from use of a robot to assist surgeons in removal of a cancerous prostate are at least as good, if not better, than the other two techniques used for a radical prostatectomy -- open or laparoscopic surgery -- according to a large meta analysis led by researchers at NewYork-Presbyterian/Weill Cornell.

South Africa's science minister urges African researchers to become more involved in solving continent's health problems

"South Africa's science minister, Naledi Pandor, has called for increased efforts by African nations to build both a greater ability to carry out research relevant to their specific health challenges, and the capacity to put such research to use," SciDev.Net reports.

Scientists identify linchpin of fat metabolism

Humans are built to hunger for fat, packing it on during times of feast and burning it during periods of famine. But when deluged by foods rich in fat and sugar, the modern waistline often far exceeds the need to store energy for lean times, and the result has been an epidemic of diabetes, heart disease and other obesity-related problems.

Study examines role of NLRP3 inflammasome in ventilator-induced lung injury

Mechanical ventilation is often lifesaving, but can also initiate or aggravate lung injury. A new study in the May issue of Anesthesiology examined the role of one particular receptor in the inflammatory pathway, the NLRP3 inflammasome, and whether it impacts ventilator-induced lung injury.

Laws against cousin marriage are not supported by science: New book

The health risks of marrying a cousin have been grossly overstated, says a new book. A better understanding of the health effects of cousin marriage could mean more appropriate marriage laws and better medical care for cousin couples and their children.

Researchers discover two new genetic loci for obesity

Obesity is influenced environmental and genetic factors. The genetic predisposition accounts for more than 50 percent of the variance in body weight. Roughly three dozen genes are known to have an influence on body weight regulation. Together with international colleagues, a group of scientists of the University of Duisburg-Essen (UDE) has identified two new genetic loci for obesity. The results are part of a large international study.

Self-degradation response to antidepressant Zoloft observed in yeast cells

Princeton University researchers have observed a self-degradation response to the antidepressant Zoloft in yeast cells that could help provide new answers to lingering questions among scientists about how antidepressants work, as well as support the idea that depression is not solely linked to the neurotransmitter serotonin.

Positive results from Repligen's RG3039 Phase 1 study for spinal muscular atrophy

Repligen Corporation today announced positive results from a Phase 1 study to evaluate the pharmacokinetic (PK) and safety profile of RG3039, a novel small molecule drug candidate for the potential treatment of spinal muscular atrophy (SMA).

MMP-10 gene plays a dual role in lung cancer

A single gene that promotes initial development of the most common form of lung cancer and its lethal metastases has been identified by researchers at Mayo Clinic in Florida.

Book aims to improve overall cardiovascular health of its readers

Dr. Antonio M. Gotto Jr., dean emeritus and co-chairman of the board of overseers at Weill Cornell Medical College, is the co-author of a new book called The Living Heart in the 21st Century. The book, a new edition in The Living Heart best-selling series, is the essential resource guide for patients about cardiovascular disease prevention and treatment.

AMSSM researcher discusses genetic associations with concussions

Thomas R. Terrell, MD presented "Prospective Cohort Study of the Association of Genetic Polymorphisms and Concussion Risk and Postconcussion Neurocognitive Deficits in College Athletes" at the 21st American Medical Society for Sports Medicine Annual Meeting in Atlanta, Ga. on April 23, 2012.

Clinical trial to evaluate IGF-1 in children with SHANK3 deficiency

In an important test of one of the first drugs to target core symptoms of autism, researchers at Mount Sinai School of Medicine are undertaking a pilot clinical trial to evaluate insulin-like growth factor (IGF-1) in children who have SHANK3 deficiency (also known as 22q13 Deletion Syndrome or Phelan-McDermid Syndrome), a known cause of autism spectrum disorder (ASD).

TopBP1 protein prevents early brain cells from DNA damage

St. Jude Children's Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer.
