Nano-bio material kills cancer cells, leaves healthy cells in unharmed

Scientists from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Chicago's Brain Tumor Center have developed a way to target brain cancer cells using inorganic titanium dioxide nanoparticles bonded to soft biological material.

Oxygen treatment may speed memory loss associated with Alzheimer's

A 65-year-old women goes into the hospital for routine hip surgery. Six months later, she develops memory loss and is later diagnosed with Alzheimer's Disease. Just a coincidence? Researchers at the University of South Florida and Vanderbilt University don't think so. They suspect that the culprit precipitating Alzheimer's disease in the elderly women may be a routine administration of high concentrations of oxygen for several hours during, or following, surgery - a hypothesis borne out in a recent animal model study.

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.

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.

Researchers discover how flu damages lung tissue

A protein in influenza virus that helps it multiply also damages lung epithelial cells, causing fluid buildup in the lungs, according to new research from the University of Alabama at Birmingham (UAB) and Southern Research Institute . Publishing online this week in the journal of the Federation of American Societies for Experimental Biology, the researchers say the findings give new insight into how flu attacks the lungs and provides targets for new treatments.

Single gene found to control growth of some cancers

Research led by Ashok Aiyar, PhD, Associate Professor of Microbiology at LSU Health Sciences Center New Orleans, showing that a single gene can control growth in cancers related to the Epstein-Barr virus and that existing therapeutics can inactivate it, will be published in the June 12, 2009 online issue of PLoS Pathogens.

Gene variation associated with resistance to chemotherapy drug in women with breast cancer

Researchers have found links between an individual's genetics and their response to treatment with chemotherapy. The findings, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and colleagues, show how a genetic variant, located in the SOD2 gene, may affect how a person responds to the chemotherapy drug cyclophosphamide. Cyclophosphamide is used in the treatment of breast and other cancers.

Researchers discover why Lou Gehrig's disease speeds along more rapidly in some patients than others

University of Florida scientists have discovered why a paralyzing brain disorder speeds along more rapidly in some patients than others - a finding that may finally give researchers an entry point toward an effective treatment for amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease.

Research offers insight into why some prostate cancer returns

The majority of men who receive one of the standard treatments for localized prostate cancer - surgery or radiation therapy - have an excellent outcome.

A new slow-release hydrogen sulfide donating molecule may hold the key to the development of new anti-inflammatory drugs

Researchers from the Peninsula Medical School in Exeter have synthesized a new molecule which releases hydrogen sulfide (H2S) - the gas that gives rotten eggs their characteristic smell and which has recently been found to be produced naturally in the body - and discovered that it could in time lead to a range of new, safer and effective anti-inflammatory drugs for human use.

Sodium bicarbonate based hydration is optimal treatment strategy to prevent contrast-induced nephropathy

The research, published in the open access journal BMC Medicine, shows that although the benefit may have been overestimated by previous studies, sodium bicarbonate is clearly superior to normal saline.

Obstructive sleep apnea increases risk of heart and vascular disease

Obstructive sleep apnea, or periodic interruptions in breathing throughout the night, thickens sufferers' blood vessels. Moreover, it increases the risk of several forms of heart and vascular disease.

A systems biology map of iron metabolism

Scientists at the Wake Forest University School of Medicine, the University of Manchester in the United Kingdom, and the Virginia Bioinformatics Institute at Virginia Tech have taken the first steps toward constructing a systems biology map of iron metabolism.

Level of cellular stress determines longevity of retinal cells

Stress can be adaptive. It can make you sharper, help you focus and it can even improve your performance. But too much of it can tax cells to the point where they can no longer cope and slowly self-destruct.

Alzheimer's disease linked to mitochondrial damage

Investigators at the Burnham Institute for Medical Research (Burnham) have demonstrated that attacks on the mitochondrial protein Drp1 by the free radical nitric oxide-which causes a chemical reaction called S-nitrosylation-mediates neurodegeneration associated with Alzheimer's disease.
