UCF professor finds new way deadly food-borne bacteria spread

University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium.

UGA researchers propose model for disorders caused by improper transmission of chromosomes

Parents of healthy newborns often remark on the miracle of life. The joining of egg and sperm to create such delightful creatures can seem dazzlingly beautiful if the chromosome information from each parent has been translated properly into the embryo and newborn.

Complications early in pregnancy or in previous pregnancies adversely affect existing or subsequent pregnancies

Amsterdam, The Netherlands: Complications in early pregnancy or in previous pregnancies can predict the
likelihood of further problems in current or subsequent pregnancies, according to research carried out by an
international group of experts.

Scientists align billion-year-old protein with embryonic heart defects

Scientists studying a vital protein called Serum Response Factor in mice have learned new and unexpected facts about SRF's role in early cardiovascular development, and how a defect in this gene may be an underlying cause in human miscarriages. At this point it is unclear whether subtle defects in SRF might also be linked to adult cardiovascular disease. However, the research provides a foundation for understanding how gene mutations may disrupt heart function, perhaps making some adults more susceptible to heart failure or irregular reactions to drugs.

Research reveals role of gene in infertility

A new paper describing discoveries about the role of a gene that is important in all animals, plants, and fungi is published in the 20 July 2004 issue of the journal Proceedings of the National Academy of Sciences. One of the discoveries is that the gene, named RAD51, plays an essential role in the the process of recombining the genetic material in chromosomes during sexual reproduction in plants. In humans, defects in this process can cause a fetus to have abnormal numbers of chromosomes, resulting in infertility, miscarriages, or birth defects. The new discoveries about the gene's role in plants suggest that it also may have an essential role in the production of sperm and egg cells in humans and other mammals.
