Robert Roberts, Baylor College of Medicine in Houston, an author of this study, offers promise that younger patients will be diagnosed earlier with the disease, instead of after puberty when hypertrophy usual...

Caffeine reduces infant blood flow

...chocardiograms (EKGs). They found that blood flow velocity in a major brain artery decreased by 18 percent an hour after caffeine administration and 25 percent after two hours. Within the intestinal arteries, the BFV decreased to 10 percent after an hour, but showed no major changes two hours after caffeine ...

Just one cigarette could cause significant damage

...lso compared augmentation index, aortic pulse wave velocity and blood pressure in 28 subjects, of whom 11 were chronic smokers, both before smoking one cigarette (nicotine content 1.2 mg.) and 15 minutes afterwards. Applanation tonometry was used to measure the augmentation index, a measure of arterial wave r...

New method of measuring arterial stiffness in elderly hypertensives

Babies Brains Are more Fragile

...my was equipped with sensors to measure rotational velocity and acceleration. "Traumatic brain injury is the most common cause of death in childhood, and child abuse is believed to be responsible for at least half of infant brain injuries. While accidental falls are a frequent cause of pediatric trauma, they...

Prostate Cancer Test Is Influenced By Age and Nutrition Factors

...studied the effect of these factors on PSA and PSA velocity in ,341 cancer-free men. They found that the PSDA velocity decreased as the age increased and high-calorific intake increased. In men who gained weight rapidly...

Adrenal Suppression not predicted by inhaled corticosteroids

...on scores (HSDS) at the time of testing and height velocity SDS (HVSDS) in the preceding year were also calculated. Adrenal suppression was demonstrated in 15 asthmatic children (20.8%) but this was only a biochemical finding. There was no correlation between adrenal response and dose or duration of treatme...

Dental Amalgam Doesn't Pose Health Risks In Children

...s of memory, attention, physical coordination, and velocity of nerve conduction. Neither did the scientists detect a pattern of decline in the test scores of individual children who received amalgam fillings. DeRouen noted that children who received amalgam fillings had slightly elevated levels of mercury in...

Sperm Cells attracted By Ovary Scent, Even in Weakened State

...m were attracted to the test substance or the swim velocity was reduced close to the test substance," Jacobson said. "In the latter case, the test substance may have had a negative influence on the sperm, resulting in suppression of their movement." Novotny is the Lilly Chemistry Alumni Chair in the Indiana U...

Doppler USG-Safer Technique For Detection Of Rh Diseases In Fetus

...ected on using Doppler ultrasound by measuring the velocity of the blood flow in the middle cerebral artery, which is the main artery that supplies blood to the brain. The investigators were of the feeling that as ultrasound is an non-invasive and a safe technique it could probably replace amniocentesis. It...

Doppler ultrasounds found to be accurate in detecting anemia in fetus

...of detecting anemia in the fetus, by measuring the velocity of blood flow in the middle cerebral artery. This test is considered// absolutely safe, also because it is non-invasive, and researchers believe that these tests can be used instead of amniocentesis.

Interferon-treatment for Hepatitis C may Cause Retinopathy

... the changes in diameter of blood vessels and the velocity of blood and also calculated retinal blood flow (RBF) and wall shear rate (WSR by implementing a laser Doppler velocimetry in 36 patients suffering from chronic hepatitis C. These patients were treated with high-dose IFN. 61% percent of these pat...

Modified Ligament Surgery Improves Outcomes Players, Athletes

...is. These sports involve a throwing motion at high velocity that exerts an exceptional force at the elbow. Repeated over time, this motion can cause inflammation and microtrauma, which can eventually lead to an MCL tear. When this ligament is torn, an individual has a full range of motion and can go about dai...

Researchers Design Pulsed Mircrojet System to Deliver Protein Drugs Without Pain or Bruising

...crojets engineered by the researchers combine high velocity (more than 100 meters per second) with very small jet diameters (between 50 and 100 micrometers), delivering only 2 to 15 nanoliters of liquid drug at a time. The research showed that the pulsed microjet system could be used to effectively deliver dr...
