Researchers Discover Mechanism Controlling the Development of Myelodysplastic Syndromes

Researchers at the Moffitt Cancer Center have discovered a control mechanism that can trigger the development of myelodysplastic syndromes (MDS), a group of blood cancers. This finding may lead to therapies capable of preventing the progression of these diseases.

Brittle-bone babies helped by fetal stem cell grafts

Osteogeneis imperfecta (OI) is a congenital bone disease that causes stunted growth and repeated, painful fracturing. Ultrasound scans can reveal fractures already in the fetus, and now an international team of researchers from Sweden, Singapore and Taiwan have treated two babies in utero by injecting bone-forming stem cells. The longitudinal results of the treatment are published in the journal Stem Cells Translational Medicine.

UCLA study challenges long-held hypothesis that iron promotes atherosclerosis

A UCLA research team has found no evidence of an association between iron levels in the body and the risk of atherosclerosis, the hardening and narrowing of the arteries that leads to cardiovascular disease, the No. 1 killer in the U.S.

Elective Early-Term Deliveries Increase Complications for Baby and Mom: Study

Enduring the last few weeks of pregnancy can be physically and emotionally challenging for some women. The aches and pains, the swelling of the limbs and the anxiety of when labor may start are part of the natural gestation process, but they also can seem unbearable. It may seem easier to relieve symptoms associated with late pregnancy by electing to deliver early, but Mayo Clinic researchers caution that there can be an increased risk of complications to the mother and the newborn associated with early-term deliveries.
