Advanced CT scans 100 percent accurate in checking for clogged arteries

In a development that researchers say is likely to quell concerns about the value of costly computed tomography (CT) scans to diagnose coronary artery blockages, an international team led by researchers at Johns Hopkins reports solid evidence that the newer, more powerful 64-CT scans can easily and correctly identify people with major blood vessel disease and is nearly as accurate as invasive coronary angiography.

Double-balloon enteroscopy offers cost-effective approach for obscure GI bleeding

A cost-effectiveness analysis conducted by researchers at Stanford University Hospital in Calif., shows that an initial double-balloon enteroscopy (DBE) is a cost-effective approach for patients with obscure gastrointestinal (GI) bleeding.

Brookhaven scientists receive patent for improved cancer therapy device

Four physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have been awarded U.S. Patent No. 7,432,516 B2 for the design of a "medical synchrotron" capable of delivering precision doses of proton radiation to cancerous tumors with minimal damage to surrounding healthy tissue.

New system helps the repair of hip joint using arthroscopy

Smith & Nephew's Endoscopy Division has announced the launch of the CROSSTRAC Hip Guide System, which enables surgeons to accurately establish pathways to diagnose and repair the hip joint using arthroscopy, or minimally invasive, repair procedures.

Nanoparticle reports on drug delivery to breast tumors, predicts response to therapy

One of the hallmarks of many nanoparticle-based anticancer therapeutics and imaging agents is that they accumulate in tumors thanks to the fact that they are small enough to escape from the bloodstream through the leaky blood vessels that surround tumors.

Scientists gain new insights into regulation of calpains

Scientists at St. Jude Children's Research Hospital have gained new insights into regulation of one of the body's enzyme workhorses called calpains.

Call for greater scrutiny of relationship between medical journalists and health care industry

The BMJ paper outlines three areas where journalists might become entangled in conflict-of-interest issues: during educational activities that may be drug company sponsored, when accepting sponsored awards, or in the day-to-day practice of reporting the news by relying too heavily on industry supplied sources.

Enzyme discovery may lead to better heart and stroke treatments

A Queen's University study sheds new light on the way one of our cell enzymes, implicated in causing tissue damage after heart attacks and strokes, is normally kept under control.

Computed tomography technology shows anorexia impairs adolescent bone development

Children and teenagers with even mild cases of anorexia exhibit abnormal bone structure, according to a new study appearing in the December issue of Radiology and presented at the annual meeting of the Radiological Society of North America (RSNA).

Proton therapy may reduce serious side effect of lung cancer treatment

Patients with locally advanced lung cancer who receive chemotherapy and proton therapy, a specialized form a radiation therapy only available in a few centers in the United States, have fewer instances of a serious side effect called bone marrow toxicity than patients who receive chemotherapy and another type of radiation therapy called intensity modulated radiation therapy (IMRT), according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Timing is everything for some heart attack patients

There is strong evidence that getting to the hospital quickly during a heart attack is critical, since early treatment saves both lives and heart muscle. And if the responsible coronary artery is completely blocked, it should be opened as soon as possible.

Study finds rise in rate of diagnostic imaging in managed care

Use of radiology imaging tests has soared in the past decade with a significant increase in newer technologies, according to a new study that is the first to track imaging patterns in a managed care setting over a substantial time period.

H5N1 protein hides in tiny tubules

A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response from infected cells, said Baylor College of Medicine researchers in an online report in the journal Nature.

Molecule stops DNA replication in its tracks

When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.

People with autism less influenced by gut instincts

People with autism-related disorders are less likely to make irrational decisions, and are less influenced by gut instincts, according to research funded by the Wellcome Trust. The study adds to the growing body of research implicating altered emotional processing in autism.

Surface analysis exposes counterfeit medicines

CERAM Surface and Materials Analysis has published a white paper highlighting how surface analysis can expose counterfeit medicines. It describes how technologies such as X-ray photoelectron spectroscopy (XPS) and Time-of-Flight Secondary Ion Mass Spectroscopy (ToFSIMS) are being used in novel ways to not only analyse the composition of various pharmaceuticals, but also to determine differences in the manufacturing processes involved.
