Half of patients in a trial have safely stopped immunosuppressant medication following a modified blood stem-cell transplant for severe sickle cell disease, according to a new study. The transplant done in the study reve...

Breast cancer screening costs for Medicare patients in the United States skyrocketed between 2001 and 2009, but the increase did not lead to earlier detection of new breast cancer cases, according to a study. While the n...

Use of exome sequencing improved the ability to identify the underlying gene mutations in patients with biochemically defined defects affecting multiple mitochondrial respiratory chain complexes (enzymes that are involve...

In patients with a traumatic brain injury (TBI), neither the administration of the hormone erythropoietin (EPO) or maintaining a higher hemoglobin concentration through blood transfusion resulted in improved neurological...

Despite strong preclinical data, the drug everolimus failed to improve overall survival in patients with advanced liver cancer, compared to placebo, according to a study. Patients with advanced hepatocellular carcinoma (...

Imagine feeling a slimy jellyfish, a prickly cactus or map directions on your iPad Mini retina display, because that's where tactile technology is headed. But you'll need more than just an index finger to feel your way a...

Researchers are homing in on a new target for malaria treatment, after developing a compound that blocks the action of a key 'gatekeeper' enzyme essential for malaria parasite survival. The compound, called WEHI-916, is ...

Researchers have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells share similar means for regulating ion intake. The new evidence is likely to a...

Use of catheter ablation is not only beneficial for treating atrial flutter but also can significantly reduce hospital visits - both inpatient and emergency - and lower the risk for atrial fibrillation, according to rese...

Every living cell's surface has a protein-embedded membrane that's covered in polysaccharide chains - a literal sugar coating. A new study found this coating is especially thick and pronounced on cancer cells - leading t...

A new study by radiation oncologists comparing the world's literature on outcomes of proton beam therapy in the treatment of a variety of advanced head and neck cancers of the skull base compared to intensity modulated r...

A trio of new studies show how the brain overcorrects to drugs and alcohol in a way that suppresses dopamine long-term, leading to withdrawal symptoms. "Addiction is a brain disease that could be treated like any other d...

A genomic analysis of clear cell renal cell carcinoma, the most common form of kidney cancer, from 72 patients has uncovered 31 genes that are key to development, growth and spread of the cancer, say researchers. This st...

The herbal extract triptolide has been used on human pancreatic cancer cells and tissue in culture by researchers. Administration of the herb decreased GRP78 protein in the cells, thereby reducing cancer cell survival an...

Bacteria love to colonize surfaces inside your body, but they have a hard time getting past your skin. Surgeries to implant medical devices give such bacteria the opportunity needed to gain entry into the body cavity, al...

Two relatively simple tactics have been used to significantly reduce the number of unnecessary blood tests to assess symptoms of heart attack and chest pain and to achieve a large decrease in patient charges, researchers...

Reduced deer populations can lead to a reduction in Lyme disease cases, researchers in Connecticut have found that after a 13-year study was conducted. White-tailed deer serve as the primary host for the adult blacklegge...

Until now, the immune cells known as 'B cells' have been thought to specialize only in the production of antibodies. A discovery by immunologists shows they also have a role to play in regulating another important aspect...

Experts describes how collaborative molecular screening platforms can help researchers understand the biology of a cancer and support the design and conduct of subsequent confirmatory trials. Collaborative molecular scre...
