FAU researchers identify endogenous process that controls reproduction of cardiac muscle cells

Heart failure is the most common cause of death worldwide. The main reason for this is that damage to the human heart causes cardiac muscle cells to die, which in turn leads to reduced heart function and death. However, this is not the case for zebrafish or amphibians. If their hearts become damaged and cardiac muscle cells die, their remaining cardiac muscle cells can reproduce, allowing the heart to regenerate.

RGS2 protein plays significant role in healthy egg-sperm union in mice

Researchers at the National Institutes of Health have discovered a protein that plays a vital role in healthy egg-sperm union in mice. The protein RGS2 can delay an egg's development into an embryo in order to allow time for sperm to arrive and merge with the egg in a healthy fertilization process. The embryo cannot survive without the male chromosomes.

Aging may trigger adaptive response to offset effects of oxidative stress on blood vessels

Although the causes of many age-related diseases remain unknown, oxidative stress is thought to be the main culprit. Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress.

Researchers develop sperm RNA diagnostic test to help determine best infertility treatment for couples

A Wayne State University School of Medicine professor, in collaboration with researchers at CReAte Fertility Center, University of Toronto, Harvard University and Georgia Reagents University, has developed the first diagnostic test for sperm RNA based on next-generation sequencing. For couples with unexplained infertility, the test may help determine the best infertility treatment for couples having difficulty conceiving.

Chromosomal abnormalities in embryos created for IVF can be predicted at earliest stage of human development

Scientists at Oregon Health & Science University, Stanford University, University of Valencia and IGENOMIX have discovered that chromosomal abnormalities in human embryos created for in vitro fertilization, or IVF, can be predicted within the first 30 hours of development at the cell-1 stage which results from the union of a female egg and male sperm.

Sociologists to explore ideas, scientific research relating to sexuality at ASA's Annual Meeting

More than 5,500 sociologists will convene in Chicago this August to explore ideas and scientific research relating to sexuality and many other topics, as part of the American Sociological Association's 110th Annual Meeting. This year's theme, "Sexualities in the Social World," shows the importance of research by sociologists in illuminating how social norms and social inequalities affect what sexual behavior is acceptable and who partners with whom.

DTC genetic testing has negative consequences in children

A woman coping with the burden of familial breast cancer can't help but wonder if her young daughter will suffer the same fate. Has she inherited the same disease-causing mutation? Is it best to be prepared for the future, or to wait? During the last decade, genetic tests have been through a sea change, both in their availability and the technologies behind them. Today there are at least 34 companies that offer direct to consumer (DTC) DNA testing, some of which return health results. And now it is possible to sequence someone's entire genetic code for the price of a laptop.

Study shows that women with endometriosis at increased risk of miscarriage, ectopic pregnancy

Women with endometriosis are at an increased risk of miscarriage and ectopic pregnancy, according to results of a huge nationwide study presented today. Moreover, women with a history of endometriosis whose pregnancies progressed beyond 24 weeks were found to be at a higher than average risk of complications, including haemorrhage (ante- and postpartum) and preterm birth.

Daily dose of aspirin effective at blocking breast tumor growth

"Take two aspirin and call me in the morning" has been the punchline for countless jokes. Could it also be good advice for cancer patients? A lab study to appear in the July 2015 issue of Laboratory Investigation found that a daily dose of aspirin was effective at blocking breast tumor growth. Previous studies have already shown a similar effect on colon, gastrointestinal, prostate, and other cancers.
