New, less invasive genetic test greatly improves pregnancy rates in older women with poor prognosis

A new test examining chromosomes in human eggs a few hours after fertilisation can identify those that are capable of forming a healthy baby, a researcher told the 25th annual conference of the European Society of Human Reproduction and Embryology today (Monday 29 June).

Scientists unearth the roots of human genetic variation

A new study at the University of Leicester is using advanced single molecule methods to explore processes that lie at the very core of DNA variation in humans.

Women warned not to wait too long to have a baby

Women are being warned that they should consider starting a family before the age of 35 or they will risk missing out on motherhood.

Inflammation of microglia may not be associated with dementia in Alzheimer's disease

The idea that anti-inflammatory drugs might protect people struggling with dementia from Alzheimer's disease has received a blow with the online release of a study of human brain tissue in Acta Neuropathologica.

Oxidative stress strongly evident in the in-utero environment of the fetus with Down syndrome

A paper published in the Proceedings of the National Academy of Sciences by Tufts Medical Center and Tufts University researchers reports that amniotic fluid surrounding Down syndrome fetuses shows oxidative stress, a condition that could harm fetal cells and play a role in affected individuals. The results demonstrate secondary adverse consequences of Down syndrome and suggest potential prenatal therapies.

People with Down syndrome may have more cancer-protective genes

Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it's been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes.

Preconceptional folate supplementation and the risk of spontaneous preterm birth

Taking folic acid supplements for at least a year before conception is associated with reduction in the risk of premature birth, according to a study by Radek Bukowski (from the University of Texas Medical Branch, United States of America) and colleagues, published in this week's PLoS Medicine.

Time of conception linked to birth defects in U.S.

A study published in the April 2009 issue of the medical journal Acta Paediatrica is the first to report that birth defect rates in the United States were highest for women conceiving in the spring and summer. The researchers also found that this period of increase risk correlated with increased levels of pesticides in surface water across the United States.

Potential pathway for drug intervention

A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial cells, according to a recent study by researchers at the Salk Institute for Biological Studies.

Molecule tracking reveals mechanism of chromosome separation in dividing cells

University of Washington (UW) researchers are helping to write the operating manual for the nano-scale machine that separates chromosomes before cell division.

Psychosocial and biological markers of daily lives of midlife parents of children with disabilities

Raising a child with a disability can cause more daily stress and long-range health problems than parenting a child without disabilities, according to a new study that looked at a clinical measure of stress along with parents' survey responses.

Breakthrough in prenatal screening for Down syndrome

Lenetix, Inc. today announced a significant step in the development of an improved first and second trimester non-invasive fetal chromosomal screening test to detect Down syndrome and other genetic fetal conditions.

Possible test for autism raises calls for an ethical debate

New research by British scientists means prenatal testing for autism is a possibility, but has evoked calls for an ethical debate on the issue.

Calls for all pregnant women to be screened for Down syndrome

Experts say Australia needs a national screening policy for Down syndrome as research shows it could halve the number of babies born with the genetic condition.

New technique provides closer look at DNA and mRNA

In a study in the advance online edition of Nature Structural and Molecular Biology, researchers from Albert Einstein College of Medicine describe a technique for looking more precisely at a fundamental step of a cell's life - a gene, DNA, being read into a message, mRNA.

Condensin II proteins found to keep chromosomes apart when necessary

If chromosomes snuggle up too closely at the wrong times, the results can be genetic disaster.

Microarray analysis improves prenatal diagnosis

A "chip" or array that can quickly detect disorders such as Down syndrome or other diseases associated with chromosomal abnormalities proved an effective tool in prenatal diagnosis in a series of 300 cases at Baylor College of Medicine, said researchers in a report that appears in the current issue of the journal Prenatal Diagnosis.

New research will explore how children with Down syndrome learn

Researchers in the U.S. say there is little information or research on how children with Down syndrome learn, especially when it comes to reading and language.

Groundbreaking study to examine how children with Down syndrome learn

Researchers at the University of Denver (DU) Morgridge College of Education are conducting a groundbreaking study that will compare two early literacy intervention approaches to educating young children with Down syndrome. The Rocky Mountain Down Syndrome Educational Fund is funding the study, which hopes to improve teaching methods for children with the condition.
