Breakthrough for stem cell research

...pecialized cells from embryos donated by infertile couples that specifically consented for their excess embryos to be used in stem cell research. These lines could eventually lead to safer treatments for conditions such as diabetes, Parkinson's disease, spinal cord injury and even breast cancer. "The new...

Birth defects: 8 million annually worldwide

...care professionals in medical genetics; Identify couples at higher risk of having children with genetic disorders; Establish newborn screening programs to identify babies born with devastating but treatable metabolic disorders such as phenylketonuria (PKU); Educate women and men of childbearing age abo...

Stress substantially slows human body's ability to heal

... The researchers focused on a group of 42 married couples who had been together an average of at least 12 ye...ded two days longer for wound-healing, compared to couples whose hostility appeared low. "Wounds on the hostile couples healed at only 60 percent of the rate...

Genetic testing still smart choice, despite uncertainties

...etic diseases during in vitro fertilization offers couples the best chance for a healthy child, but a genetic...aid. But the small margin of error shouldn't stop couples from having preimplantation genetic diagnosis, said Jamie Grifo, M.D., Ph.D., a professor of obstetr...

New understanding of jet lag

...ly, the new research identifies the mechanism that couples the two parts of the SCN clock." He suggested that the differing rates of synchronization that occurs in the central clock may be part of a complex evolutionary adaptation to seasonal light changes, but the mechanism, in effect, becomes confused whe...

New Discovery May Help Doctors Treat Infertility

...Health, which funded the research. “If we can help couples understand the reasons for their infertility, doctors can further define their treatment options, help them to minimize the expense and risk of taking drugs that may be less effective for them, and increase their chances of having a safe and healthy ...

Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...yos donated for research under HFEA regulations by couples undergoing IVF treatment. In addition, we utilised cell lines from the University of Wisconsin. "The human embryonic stem cells were allowed to develop into collections of cells called embryoid bodies. The embryoid bodies were tested to see which ge...

Research shows smoking adds a decade to reproductive age of IVF patients

Discovery clarifies role of peptide in biological clock

..., the synchronicity was restored, showing that VIP couples pacemaker cells and drives rhythms in slave cells. "VIP between SCN neurons is like a rubber band between the pendulums of two grandfather clocks, helping to synchronize their timing. Some researchers had proposed that knocking out VIP or the recept...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...n the same procedure that's used successfully when couples freeze embryos. When eggs are warmed after vitrification, fertilization rates with conventional IVF are low. Instead, researchers have found, a single sperm cell must be injected into a single oocyte, a technique called intracytoplasmic sperm inject...
