Scientists combine two nanoparticles into one tiny package

Nanoparticles are being developed to perform a wide range of medical uses - imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.

Anemia increases risk of death in people aged 85 and older

Anemia in very elderly people aged 85 and older appears to be associated with an increased risk of death, according to a new study in CMAJ (Canadian Medical Association Journal).

miR-21 molecule plays early and important role in nonsmoking lung cancer

The cause of lung cancer in never-smokers is poorly understood, but a study led by investigators at the Ohio State University Comprehensive Cancer Center and at the National Cancer Institute has identified a molecule believed to play an early and important role in its development.

Gene expression patterns in cancer could aid early screening and prevention

Distinctive patterns of genes turned off - or left on - in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them, Medical College of Georgia scientists say.

Majority of health care leaders support public health care option

By a wide margin, health care leaders believe that individuals should have a choice of public and private health plans, and strongly support other central components of health reform such as innovative provider payment reform and a national insurance health exchange with strong standard-setting authority.

Deferoxamine could help diabetics heal wounds

A drug used to remove iron from the body could help doctors fight one of diabetes' cruelest complications: poor wound healing, which can lead to amputation of patients' toes, feet and even legs.

Current diagnostic tests for ovarian cancer woefully ineffective

A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests. Still, if that hurdle can be overcome, there is good reason to believe that testing could make a big difference: The window of opportunity for treating these clinically undetectable cancers before they become life threatening is surprisingly long: about four years.

Anesthesia not harmful for babies during birth process

Mayo Clinic researchers have found that children exposed to anesthesia during Cesarean section are not at any higher risk for learning disabilities later in life than children not delivered by C-section. These findings are reported in the current issue of the journal Anesthesiology.

Repeated stress signals made in cells with metabolism-associated disease encourage the growth of invading bacteria

Mitochondrial diseases disrupt the power generating machinery within cells and increase a person's susceptibility to bacterial infection, particularly in the lungs or respiratory tract.

Coronary calcium scoring may predict heart attack risk

Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a study published in the online edition of Radiology.

Artificial intelligence used to diagnose metastatic cancer

When doctors are managing care for women with breast cancer, the information available to them profoundly influences the type of care they recommend. Knowing whether a woman's cancer has metastasized, for instance, directly affects how her doctors will approach treatment -- which may in turn influence the outcome of that treatment.

Smoking increases likelihood that pancreatic ductal adenocarcinoma will become metastatic

Smoking has once again been implicated in the development of advanced cancer. Exposure to nicotine by way of cigarette smoking may increase the likelihood that pancreatic ductal adenocarcinoma will become metastatic, according to researchers from the Kimmel Cancer Center at Jefferson.

Cost effectiveness study looks at potential value of new genetic test for guiding chemotherapy treatment

For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. But for more than one in 10 of these patients, a variation in their DNA means that this treatment could result in a severe reduction in their white blood cell count, leading to a high risk of bacterial infection and possible subsequent death.

Research adds to growing understanding of the metabolic consequences of assisted reproductive techniques

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that assisted reproductive techniques alter the expression of genes that are important for metabolism and the transport of nutrients in the placenta of mice.

System 50 years out of date for chronic illness

Many people with chronic health conditions have more than one disease, which makes caring for them much more complex. Unfortunately, the way our health system is structured now, and the way it is paid for, reflects the health needs our society had about 50 years ago.

Nanodiamonds hold promise for wound-healing applications

Bacterial infection is a major health threat to patients with severe burns and other kinds of serious wounds such as traumatic bone fractures. Recent studies have identified an important new weapon for fighting infection and healing wounds: insulin.

New clues about the roots of neurological disease

Switching off a key DNA repair system in the developing nervous system is linked to smaller brain size as well as problems in brain structures vital to movement, memory and emotion, according to new research led by St. Jude Children's Research Hospital scientists.
