Corticosteroids may be linked to an increased risk for atrial fibrillation

High doses of medications known as corticosteroids may be linked to an increased risk for atrial fibrillation, a heart rhythm disorder characterized by an irregular heartbeat, according to an article in the May 8 issue of Archives of Internal Medicine.

Social stress prompts hamsters to overeat

Put a mouse or a rat under stress and what does it do? It stops eating. Humans should be so lucky. When people suffer nontraumatic stress they often head for the refrigerator, producing unhealthy extra pounds.

Summer sun safety - research reveals significant link to melanoma

Fifty years of medical studies show that sun exposure is a primary component in the development of melanoma, the most serious and deadly type of skin cancer, report leading dermatologists in the April 2006 issue of Dermatologic Surgery.

Silica nanoparticles shown to boost reflection of ultrasonic energy

Targeted nanoparticles may eventually help physicians detect the very earliest stages of cancer using readily available ultrasound equipment, a new study from investigators at The Ohio State University suggests.

Advancing nanoparticle-based imaging and therapy of brain cancer

Brain cancer is one of the most difficult malignancies to detect and treat, in large part because of the difficulty in getting imaging and therapeutic agents past the so-called blood-brain barrier and into the brain.

Nanoparticle system for imaging and delivering drugs to tumors

By melding magnetic and luminescent properties with an easily modified surface, a team of investigators at the National Research Council of Canada have created what could prove to be a highly versatile nanoparticle system for imaging and delivering drugs to tumors.

Scientists assemble a complete viral coat around a gold nanoparticle

Using a short piece of DNA as a template, a team of investigators at North Carolina State University has assembled a complete viral coat around a gold nanoparticle.

Effective gene suppression using small interfering RNA in hard-to-transfect human T cells

A technical advance in laboratory techniques may provide biology researchers broader access to RNA interference, a process of blocking the activity of targeted genes. RNA interference has recently emerged as an important tool in studying how genes function in normal biological processes and in disease.

Circulating tumor cells in the bone marrow of patients with metastatic renal cell carcinoma may be prognostic of outcome

Circulating tumor cells in the blood and bone marrow have been examined in a variety of malignancies, including colorectal, breast, and head & neck cancers, to determine their prognostic significance.

Scientists discover molecular security mechanism for keeping gene mutations in check

Everyone knows mutations - genetic mistakes in DNA, the material of heredity - are bad: The more mutations in the cell's DNA, the higher the risk of cancer developing.

Study highlights increased passive smoking risk at home

Most non-smoking mothers recognise the need to protect sick children from smoking husbands, but persuading their spouse to quit isn't always an option, according to research published in the latest Journal of Advanced Nursing.

Breast removal not the only treatment option for non-invasive breast cancer

Breast conserving surgery, long known to be successful at treating the more common invasive cancer, can also be effective for this pre-invasive condition, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.

Gene silencing protein discovered

A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off -in this case, the turning off of thousands of nearly identical genes in a hybrid plant.

A pericellular collagenase directs the 3-D development of white adipose tissue

In the journal Cell, researchers report the serendipitous discovery that the initial development of fat requires a "remodeling" protein that must first make way for the lipid-laden tissue's growth.

Novel protein JHDM2A offers new look at male hormone regulation

For the second time in less than a year, University of North Carolina at Chapel Hill scientists have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent.

Bacterial binding in the stomach

Scientists have determined that decay-accelerating factor (DAF), a protein found in epithelial cells in the stomach, acts as a receptor for the bacteria Helicobacter pylori. Blocking this interaction could lead to new drugs that reduce the risk of peptic ulcer disease or gastric cancer.

MicroCT-based virtual histology

Utah and Texas researchers combined miniature medical CT scans with high-tech computer methods to produce detailed three-dimensional images of mouse embryos - an efficient new method to test the safety of medicines and learn how mutant genes cause birth defects or cancer.

Important insights into how cells regulate certain growth-proteins

Researchers here have discovered a new mechanism used by cells - and manipulated by retroviruses - to control the making of certain essential proteins, including some involved in cancer.

New procedure to treat fractured vertebrae caused by spinal tumors

A radiologist at the University of California, San Diego (UCSD) School of Medicine has developed a new procedure to treat fractured vertebrae caused by spinal tumors, a procedure that may decrease the risk of complications, which are experienced by 5 to 10% of patients with malignant tumors of the spine.
