Babies born to native high-altitude mothers have decreased risk of low birth weight

... women. There were no differences in fetal growth or birth weight between the two groups. At high altitude, the uterine artery of both groups dilated less, reflecting the oxygen-poor environment. Among the high-altitude group, the Andean women's blood flow was 68% greater at 20 weeks of pregnancy ...

Statins may treat blood vessel disorder that can lead to fatal strokes

... is recruiting 50 to 100 people diagnosed with CCM to join a pilot trial of statins. CCM is a disorder in which blood vessels in the brain become dilated and weakened, and leak blood, causing strokes, headaches, seizures or other problems. Diagnosing CCM can be problematic. Some people are diagnosed ...

Three Dimensional Visualization of Right Ventricle Provides Important Information for Treatment of Patients with Tetralogy of Fallot, According to a Study in The American Journal of Cardiology

... pulmonary stenosis. The three dimensional models created in the study provided volumetric data that was used to determine that patients with TOF had dilated right ventricles compared to individuals with normal function (end-diastolic volume index 216+/- 99 vs 81 +/- 16 ml/mm, p <0.001). The three ...

UVa biomedical engineering study shows magnetic field can reduce swelling

... static magnetic fields - the force created by the magnets. Morris and Skalak found that the force had a significant effect: the vessels that had been dilated constricted, and the constricted vessels dilated, implying that the magnetic field could induce vessel relaxation in tissues with constrained blood ...

High blood pressure, low energy -- a recipe for heart failure

... In mice that lacked ERR alpha and that were exposed to pressure overload, the researchers observed signs of early heart failure: the mouse hearts dilated and didn't contract effectively, the heart walls thinned, fibrous connective tissue accumulated and some heart cells died. They also saw that the ...

Fruit fly's beating heart helps identify human heart disease genes

... into the fly genome a mutated gene that causes dilated cardiomyopathy in humans. This condition is often ... the fly the gene that we know is implicated in dilated cardiomyopathy in humans, we imaged the adult fly ... fly the actual physiologic changes caused by dilated cardiomyopathy." The Duke team is currently ...

Protein overexpression at heart of heart failure

... Chronic heart failure resulting from dilated cardiomyopathy is rapidly emerging as a disease of epidemic proportions.1 Molecular mechanisms are being studied and advances have been made in a ...

A surprise about our body clock

... the injured site and regenerate the injured heart. Their heart function was dramatically impaired and, 42 days after a heart attack, their hearts dilated to twice the size of the normal mouse heart. However, the heart function of the c-kit defective mice could be restored to normal by restoring the ...

Healing the heart with bone marrow cells

... the injured site and regenerate the injured heart. Their heart function was dramatically impaired and, 42 days after a heart attack, their hearts dilated to twice the size of the normal mouse heart. However, the heart function of the c-kit defective mice could be restored to normal by restoring the ...

UF scientists test improved gene therapy method for hereditary heart conditions

... faulty genes or congenital metabolic diseases, including atherosclerosis, stroke, muscular dystrophy and an enlargement of the heart muscle known as dilated cardiomyopathy. But efforts to begin testing it in people have been slowed by the need to find ways to deliver corrective genes easily and ...

Prenatal nicotine exposure reduces breathing response of newborns...

... mother and to drive down medical costs, said Han. The mother, who had the presence of Bergeyella, came to MetroHealth when in preterm labor and dilated at 24 weeks. She was induced after it was determined by low glucose levels and elevated white blood cell counts in her amniotic fluid that she had ...
