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.

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.

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.

Calcium carbonate templates for drug delivery Posted: 04 Jul 2012 09:40 AM PDT 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.

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.
