Sequencing of fetal genomes using only maternal blood sample

Posted: 04 Jul 2012 03:21 PM PDT

Researchers have for the first time sequenced the genome of an unborn baby using only a blood sample from the mother. The new technique hinges on the fact that pregnant women have DNA from both their cells and the cells of their fetus circulating freely in their blood.

Freezing all embryos in IVF with transfer in a later non-stimulated cycle may improve outcome

Posted: 04 Jul 2012 09:43 AM PDT

There is growing interest in a "freeze-all" embryo policy in IVF. Such an approach, which cryopreserves all embryos generated in a stimulated IVF cycle for later transfer in a non-stimulated natural cycle, would avoid any of the adverse effects which ovarian stimulation might have on endometrial receptivity during the treatment cycle.

Fertility preservation with cryopreservation of ovarian tissue: From experimental to mainstream

Posted: 04 Jul 2012 09:43 AM PDT

Although the first successful preservation of fertility from the freezing, thawing and grafting of ovarian tissue was reported eight years ago, the technique has remained experimental and confined to a few specialist centers. Now, with the announcement of a first pregnancy (and subsequent live birth) in Italy following the transplantation of ovarian tissue, there are indications that fertility preservation is moving into the mainstream of reproductive medicine and into a greater number of centers.

Single embryo transfer reduces the risk of perinatal mortality in IVF

Posted: 04 Jul 2012 09:43 AM PDT

A policy of single embryo transfer (SET) reduces the risk of perinatal mortality in infants born as a result of IVF and ICSI. The conclusion emerged from an analysis of more than 50,000 births recorded in the Australian and New Zealand Assisted Reproduction Technology Database between 2004 and 2008, where the introduction of an SET policy has been associated with a reduction in overall perinatal mortality for IVF and ICSI babies.

Strawberries, the traditional summer treat associated with Wimbledon could be serving up some unexpected health benefits.

Development of antibiotic resistance more predictable than expected

Posted: 04 Jul 2012 09:41 AM PDT

Research has shown that the development of bacteria with resistance against the antibiotic cefotaxime occurs more often and more predictably than was previously assumed. Bacterial populations were found to have many mutations that increase resistance and therefore have a negative effect on public health. Moreover, the effects are such that it can be predicted that the development of bacterial strains with a resistance against cefotaxime will progress in a similar way in different patients from different locations.

Toward an alternative for antibiotics to fight bacterial infections?

Posted: 04 Jul 2012 09:41 AM PDT

Mice that do not produce the receptor protein NLRP6, are better protected against bacterial infections and can more easily remove bacteria from the body. Therapeutic drugs that neutralize NLRP6 could be a possible treatment option, in addition to the use of antibiotics, for fighting bacterial infections.

Calcium carbonate templates for drug delivery

The fast and targeted delivery of drugs could soon be made easier. Microcontainers for medical substances can be produced in different sizes using calcium carbonate microspheres as templates, new research shows.

New drug prospect offers hope against hookworm infections

Posted: 03 Jul 2012 11:18 PM PDT

A drug candidate that is nearing clinical trials against a Latin American parasite is showing additional promise as a cure for hookworm, one of the most widespread and insidious parasites afflicting developing nations.

Rate of community-onset MRSA infections appears to be on the decline

Posted: 03 Jul 2012 11:17 PM PDT

In analysis that included more than 9 million US Department of Defense nonactive and active duty personnel, the rates of both community-onset and hospital-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia decreased from 2005 to 2010, while the proportion of community-onset skin and soft tissue infections due to MRSA has more recently declined, according to a new study.

Brazil has laws that protect against 'Big Food' and 'Big Snack'

Posted: 03 Jul 2012 11:17 PM PDT

Under pressure from civil society organizations, the Brazilian government has introduced legislation to protect and improve its traditional food system, standing in contrast to the governments of many industrialized countries that have partly surrendered their prime duty to protect public health to transnational food companies, argue nutrition and public health experts.

Potential food crisis with global warming, UK scientists warn

Posted: 03 Jul 2012 11:15 PM PDT

UK consumers could face dramatically reduced food choices in the future unless much more is done to cut greenhouse gas emissions, a hard-hitting report warns. Food which families now take for granted, such as meat and fresh vegetables, could become too expensive for many if global temperatures rise in line with the current trends and reach 4°C within the lifetime of many people.

Heat wave especially dangerous for kids

Posted: 03 Jul 2012 05:05 PM PDT

Extreme heat continues to plague the nation with many areas seeing record temperatures. Though everyone needs to take precautions when it comes to dangerous heat, it's especially important to watch your kids. Children are at a greater risk than adults of sustaining a heat injury.
