Study: Aerobic physical activity linked to reduced risk of dementia

Any exercise that gets the heart pumping may reduce the risk of dementia and slow the condition's progression once it starts, reported a Mayo Clinic study published this month in Mayo Clinic Proceedings.

Scientists invent new system that uses magnetism to purify hybrid nanoparticles

A team of Penn State University scientists has invented a new system that uses magnetism to purify hybrid nanoparticles -- structures that are composed of two or more kinds of materials in an extremely small particle that is visible only with an electron microscope.

Biochemists reveal interaction between tumor suppressor protein and chaperone

Every cell has thousands of proteins whose activity and lifetime must be regulated to control the cellular life cycle from cell division to cell death. The heat shock protein Hsp90 plays a key role in this process. It is a so-called chaperone, a quality controller, as it were. It monitors and controls the quality and activity of many important signal proteins and helps them take on the right form. When the cell is exposed to high stress levels from heat or a lack of oxygen, Hsp90 is produced in larger quantities to shield its partner proteins from damage.

Adding azithromycin to usual daily treatment for COPD reduces acute exacerbations by 27%

Richard Casaburi, Ph.D., M.D., principal investigator at Los Angeles Biomedical Research Institute (LA BioMed), is co-author of a recent study that should help improve the condition for the millions of individuals who suffer from chronic obstructive pulmonary disease, better known as COPD.

Researchers rethink fenretinide for prevention of oral cancer

Scientists on the cutting edge of biomedical research know that research is a process - a combination of successes and failures that inform the next step forward. However, for some researchers at The Ohio State University progress means taking a step back. Supported by the Ohio State University Center for Clinical and Translational Science (CCTS), these scientists are using failed and forgotten research to uncover future treatments for major health conditions as diverse as oral cancer and stroke.

Glioma stem cells can change their metabolic state at will, finds study

The metabolic state of glioma stem cells, which give rise to deadly glioblastomas, is significantly different from that of the brain cancer cells to which they give birth, a factor which helps those stem cells avoid treatment and cause recurrence later.

New blood test could help identify babies at risk of sickle cell disease

A new blood test is being developed by researchers in Cambridge and Oxford, which, for the first time, could help identify babies at risk of a severe form of sickle cell disease, allowing immediate and more intensive treatment to be given, thanks to a grant from children's charity Action Medical Research.

C. sporogenes bacterium could be used as vehicle to deliver drugs in frontline cancer therapy

A bacterial strain that specifically targets tumours could soon be used as a vehicle to deliver drugs in frontline cancer therapy. The strain is expected to be tested in cancer patients in 2013 says a scientist at the Society for General Microbiology's Autumn Conference at the University of York.

Scientists sequence ten variants of E. coli O104:H4 outbreak strain across the world

Ten variants of the deadly Escherichia coli strain that hit Germany in May 2011 have been sequenced across the world. The unprecedented level of collaboration across the scientific community should give insight into how the outbreak arose, says a scientist at the Society for General Microbiology's Autumn Conference 2011.

Loyola surgeons use new, less invasive catheter technique to treat cystic fibrosis

Cystic fibrosis patient Daniel Sammons had undergone a successful double lung transplant at Loyola University Medical Center, but he still had one major health issue.

Combination of resistance training, AT does not benefit cardiac patients

For patients undergoing rehabilitation following cardiac events, aerobic exercise training (AT) is widely recommended. Resistance training (RT) has also been shown to be beneficial because it enhances muscular strength and endurance, functional capacity and independence, and quality of life, while reducing disability.

Exercise triggers influential stem cells to become bone instead of fat

McMaster researchers have found one more reason to exercise: working out triggers influential stem cells to become bone instead of fat, improving overall health by boosting the body's capacity to make blood.

New medicines to target LPA receptors may prevent serious developmental brain diseases

Examining brain damage that occurs when fetuses in the womb are deprived of oxygen, researchers at The Scripps Research Institute have discovered that damage does not occur randomly but is linked to the specific action of a naturally occurring fatty molecule called LPA, acting through a receptor that transfers information into young brain cells.

Two ROC trials evaluate new strategies for CPR following cardiac arrest

Researchers with the Resuscitation Outcomes Consortium, which includes the University of Alabama at Birmingham, report Sept. 1 in the New England Journal of Medicine on the first two large-scale ROC trials. Both trials were evaluating new strategies for cardiopulmonary resuscitation following cardiac arrest.

UTHealth Phase I trial: Bone marrow stem cell therapy feasible, safe for acute stroke patients

Using a patient's own bone marrow stem cells to treat acute stroke is feasible and safe, according to the results of a ground-breaking Phase I trial at The University of Texas Health Science Center at Houston.

New implantable micro oxygen generator improves effectiveness of anticancer tharapy

Researchers have created and tested miniature devices that are implanted in tumors to generate oxygen, boosting the killing power of radiation and chemotherapy.

Cell's reserve fighting force shrinks with age: Study

When the body fights oxidative damage, it calls up a reservist enzyme that protects cells - but only if those cells are relatively young, a study has found.

Balloon pump use prior to PCI does not reduce infarct size in STEMI patients without shock

Intra-aortic balloon pump counterpulsation prior to PCI in patients with ST segment elevation MI does not reduce infarct size as measured by MRI, according to results from the Counterpulsation Reduces Infarct Size Acute Myocardial Infarction (CRISP AMI) trial.

Study finds higher incidence of arrhythmias in elite cross-country skiers

A Swedish study presented at the ESC Congress 2011 today, found a higher incidence of arrhythmias in cross-country skiers with a long history of endurance training.

Leucine may help people burn fat during periods of food restriction

Research on Mt. Everest climbers is adding to the evidence that an amino acid called leucine - found in foods, dietary supplements, energy bars and other products - may help people burn fat during periods of food restriction, such as climbing at high altitude, while keeping their muscle tissue.
