Stem Cell :: Study Reveals How Stem Cells Decide To Become Either Skeletal or Smooth Muscle

Researchers have discovered a key protein that controls how stem cells “choose” to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published today in the Proceedings of the National Academy of Sciences (PNAS).

Breast Cancer :: Women who bear children have a reduced risk of developing breast cancer

The benefits of motherhood: Fetal Cell “Transplant” could be a hidden link between childbirth and reduced risk of breast cancer. Some benefits of motherhood are intangible, but one has been validated through biostatistical research: women who bear children have a reduced risk of developing breast cancer.

Pregnancy :: Modulating fat levels essential for successful pregnancy

A new mouse study has provided a potential reason for early pregnancy loss in humans. Female mice lacking a protein known as sphingosine kinase 1 (Sphk1) and expressing reduced levels of Sphk2 were found to experience early pregnancy loss and therefore to be infertile. As Sphk1 and Sphk2 are involved in metabolizing fats known as sphingolipids, the authors suggested that disturbances in sphingolipid metabolism might be a cause of early pregnancy loss in humans.

Pregnancy :: Researchers test old drug with new hopes for pre-eclampsia cure

Researchers at the University of Texas Medical Branch at Galveston are trying to determine whether a drug already available to heart patients can also be used to delay delivery in expectant mothers with severe pre-eclampsia. If so, this groundbreaking study would give hope to hundreds of thousands of women who experience this life-threatening disorder each year.

Pregnancy :: PFOS and PFOA exposure associated with lower birth weight and size

Exposure to perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in the womb is statistically associated with lower weight and head circumference at birth, according to an analysis of nearly 300 umbilical cord blood samples led by researchers at the Johns Hopkins Bloomberg School of Public Health.

Migraine :: Women with migraines and visual symptoms may have higher stroke risk

Women who have migraine headaches with visual symptoms (or aura) may be at increased risk for stroke compared to women who do not have migraines, researchers reported in Stroke: Journal of the American Heart Association. The risk association between stroke and migraines also increases when other factors are added, such as recent onset of these headaches, smoking and oral contraceptive use.
