Isotretinoin and acne

The most potent drug available for the treatment of acne is 13-cis retinoic acid (13-cis RA; also known as isotretinoin); however, little is known about the mechanism by which it acts.

Large-scale study of traumatic brain injury

In a rare, large-scale study of traumatic brain injury (TBI) patients who span the full range of severity from mild to moderate and severe, Canadian researchers have found that the more severe the injury, the greater the loss of brain tissue, particularly white matter.

Device allows scientists to control gene activity across generations of cells

Just as cells inherit genes, they also inherit a set of instructions that tell genes when to become active, in which tissues and to what extent.

Ten years down the line a pill to cure obesity

British scientists say they may have found a new way to treat obesity by stopping the stomach from expanding.

Nanotechnology advances brain cancer detection and therapy

Brain cancer is one of the most aggressive and lethal of malignancies, made even more difficult to treat by the fact that most anticancer drugs have a hard time even getting to the tumors.

Preclinical antitumor efficacy evaluation of dendrimer-based methotrexate conjugates

Although a variety of nanoparticles continue to show promise for improving cancer imaging and therapy, regulators and drug developers are concerned that these delivery systems may prove difficult to manufacture on a consistent basis, which is key for any agent designed for use in humans.

Fluorescent nanoparticles image tumor marker in animals

Since 2004 the U.S. Food and Drug Administration has approved three new-generation anticancer therapies that target epidermal growth factor receptor (EGFR), a protein that is greatly overexpressed on certain types of tumors, including some forms of colorectal and lung cancer.

Gold nanoparticle-based colorimetric assay for the direct detection of cancerous cells

Early detection of tumors is one of the Holy Grails of cancer research, an achievement that would greatly improve cancer therapy and prognosis. Two new reports describe different but promising approaches to solving this problem.

Short RNA strand helps exposed skin cells protect body from bacteria, dehydration and even cancer

Every minute, 30,000 of our outermost skin cells die so that we can live.

New way to develop tumor vaccines

Researchers at the University of Southern California (USC) have uncovered a new way to develop more effective tumor vaccines by turning off the suppression function of regulatory T cells.

Novel mechanism found that may boost impaired function of leukemia protein

A new study led by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) reports on a novel mechanism that can enhance the function of a protein that is frequently impaired in patients with acute forms of leukemia.

Clinical trial shows reduction in mortality for children with severe Langerhans cell histiocytosis

A new international study finds that introducing an increased intensity of chemotherapy in children with severe Langerhans cell histiocytosis (LCH) can reduce the mortality rate for this disorder by as much as 20 percent when the patient demonstrates a rapid response to such treatment.

Adult stem cell changes underlie Hutchinson-Gilford Progeria syndrome associated with accelerated aging

Adult stem cells may provide an explanation for the cause of a Hutchinson-Gilford Progeria Syndrome (HGPS), a rare disease that causes premature aging in children, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).

Researchers investigate predictors for sickle-cell-anemia complications

Researchers at UT Southwestern Medical Center have determined that the level, or saturation, of oxygen in blood could be used to identify children with sickle cell anemia who are at an increased risk of stroke.

New super technology to detect food-borne pathogens, toxins

Researchers have developed a new technology that can simultaneously screen thousands of samples of food or water for several dangerous food-borne pathogens in one to two hours.

New discovery on programmed cell death

Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process.

HIV blocking gene found

A team of researchers at the University of Alberta, including a scientist at the University of Pennsylvania, have discovered a gene that is able to block HIV, and thought to in turn prevent the onset of AIDS.

New global study of targeted therapies for breast cancer

Two targeted medications designed to treat an aggressive form of breast cancer are being tested in a new study involving 8,000 participants in 50 countries across six continents -- a clinical trial that investigators hope will provide a new model for global cancer research.
