Changes in chromosomal constitution of preimplantation embryos suggest caution in genetic screening

06-18-2007 · EurekAlert!

Embryos that are selected out as abnormal can undergo chromosomal modifications, a scientist will tell the annual conference of the European Society of Human Genetics today, Tuesday, June 19. Tsvia Frumkin, from the Racine IVF unit, LIS Maternity Hospital, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel, will tell the conference that her team's findings meant that the results of preimplantation genetic screening for chromosomal abnormalities were not always reliable, and should be interpreted with caution.

Decoding effects of toxins on embryo development
10-24-2007 · EurekAlert!
Changes in gene expression patterns in zebrafish embryos resulting from exposure to environmental toxins can identify the individual toxins at work, according to research published in the online open access journal Genome Biology. The genetic response of zebrafish to each toxin can be read like a barcode, offering researchers a potential method for identifying the effects of the toxin on developing vertebrate embryos.

People at genetic risk for Alzheimer's age mentally just like noncarriers
01-07-2007 · EurekAlert!
Australian researchers say that a genotype that heightens the risk for Alzheimer's disease does not contribute to cognitive change during most of adulthood. The largest study of its kind has found that carriers and noncarriers show the same type and extent of normal age-related cognitive declines, decades before carriers start to more often develop symptoms of dementia. The findings suggest that the higher-risk genotype acts only in later years to layer disease on top of normal aging.

Human embryonic stem cells derived from preimplantation genetically diagnosed embryos
11-14-2007 · EurekAlert!
A human stem cell line derived from embryos that were identified by preimplantation genetic diagnosis to carry the mutation for fragile X syndrome has provided an unprecedented view of early events associated with this disease. In addition to giving scientists fresh insight into fragile X, results from this unique model system have emphasized the value of this new source of embryonic stem cells and may have a significant impact on the way that genetic diseases are studied in the future.

Clock comparison yields clues to 'constant' change
02-15-2007 · EurekAlert!
Years of comparisons among the world's best atomic clocks -- based on different atoms -- have established the most precise limits ever achieved in the laboratory for detecting possible changes in so-called 'constants' of nature. The comparisons at NIST may help scientists test the latest theories in physics and develop a more complete understanding of the history of the universe.

The human brain: Detective of auditory and visual change
01-18-2008 · EurekAlert!
The human brain is capable of detecting the slightest visual and auditory changes. Several studies have indicated, however, that even a small span of time in between pre- and post-change images can disturb the brain's ability to detect visual discrepancies. In a recent study, psychologists assessed the effect of time gaps on change detection in audition.

Lifestyle changes can improve male sexual function, according to new study
02-01-2007 · EurekAlert!
In a study published in the February 2007 issue of the American Journal of Medicine, researchers report that erectile dysfunction was significantly and independently associated with age, cardiovascular disease, diabetes, and lack of physical activity. There was an especially high prevalence of erectile dysfunction among men with hypertension and diabetes, suggesting that screening for erectile dysfunction in these patients may be warranted.
