Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells

To investigate tumors, pathologists currently rely on labor-intensive microscopic examination, using century-old cell-staining methods that can take days to complete and may give false readings. A lightning-fast laser technique, led by Sandia National Laboratories researcher Paul Gourley, has provided laboratory demonstrations of accurate, real-time, high-throughput identification of live...

Pulsating ultrasound enhances gene therapy for tumors

High-intensity focused ultrasound emitted in short pulses is a promising, non-invasive procedure for enhancing gene delivery to cancerous cells without destroying healthy tissue, according to a study in the May issue of the journal Radiology. High-intensity focused ultrasound (HIFU) is more powerful than standard ultrasound. HIFU can destroy tumors through long and continuous exposures tha...

Penn researchers study the use of ultrasound for treatment of cancer

For the first time, ultrasound is being used in animal models ?to treat cancer by disrupting tumor blood vessels. Researchers at the University of Pennsylvania School of Medicine completed a study in mice in which they used ultrasound both to see a tumor's blood perfusion and then to treat it with a continuous wave of low-level ultrasound. After three minutes of treatment at an intensity similar...

3D ultrasound device poised to advance minimally invasive surgery

Three-dimensional ultrasound probes built by researchers at Duke's Pratt School of Engineering have imaged the beating hearts of dogs. The engineers said their demonstration showed that the probes could give surgeons a better view during human endoscopic surgeries in which operations are performed through tiny "keyhole" incisions. If the probes prove beneficial in human testing, the advanc...

Ultrasounds show mothers' drinking shrinks fetal brain

Routine ultrasounds show that heavy drinkers who continue to imbibe after learning they are pregnant may carry fetuses with reduced skull and brain growth compared to those of abstainers or quitters, says a new study. Although the alcohol-exposed babies' growth remained within normal range, the findings reveal effects of drinking on the developing human brain. The study will appear in the...

Ultrasound helps stroke treatment

According to surgeons, they use sound waves to pulverize gallstones and now stroke experts are trying to determine if less powerful ultrasound can improve the efficacy of the clot-busting drugs used to restore blood flow to the brain.// Dr. Andrei Alexandrov, of the University of Texas, said he was using intracranial ultrasound to track the efficacy of the clot-busting drug called tPA or alteplas...

Ultrasound test may detect heart condition early

According to a new report, a type of ultrasound test may be able to identify patients with a heart condition that is one of the most common causes of sudden death in young people.The condition, hypertrophic cardiomyopathy (HCM), can be caused by more than 100 different mutations in as many as 10 genes. In HCM, the heart muscle thickens, eventually limiting the organ's ability to pump blood and pu...

Adding contrast improves ultrasound's ability to detect prostate cancer

Contrast enhanced color Doppler ultrasound is better than unenhanced ultrasound at detecting prostate cancer, according to a report published in the July issue of The Journal of Urology.
