Psychological depression contributes to worse medical outcomes for patients with heart failure

Heart failure, also known as congestive heart failure, is marked by the inability of the heart muscle to pump enough oxygen and nutrients in the blood to the body's tissues.

New test identifies suitable lymphoma patients likely to respond to new therapy

Researchers at the Albert Einstein College of Medicine of Yeshiva University have discovered a genetic signature identifying cases of lymphoma that are uniquely susceptible to a newly developed molecular targeted therapy. As a result, physicians organizing clinical trials of the new therapy will be able to enroll patients who'll be most likely to benefit from it.

Targeting bladder tumor cells in vivo and in the urine with a peptide identified by phage display

Efforts to create nanoparticles that deliver anticancer drugs or imaging agents to tumors while avoiding healthy cells are often stymied by a lack of known tumor targets, that is, molecules found on the surface of malignant cells but not healthy cells.

Peptide vaccine fights off breast tumors with help of bacteria-mimicking agents

With the help of immune system-stimulating molecules that mimic bacterial components, researchers have used a type of cancer vaccine to both delay and prevent breast tumors in mice.

Natural fibre may help overweight achieve a healthy body weight

It sounds almost too good to be true, but Dr. Raylene Reimer, a researcher at the University of Calgary, Faculty of Kinesiology, believes she may have found an important weapon in the war against obesity.

Calpain-mediated mGluR1-alpha truncation

Tricking a key enzyme can soothe over-excited receptors in the brain, say neuroscientists, calling this a possible strategy against stroke, Alzheimer's and other neurodegenerative diseases.

A prediction rule for disease outcome in patients with recent-onset undifferentiated arthritis

Marked by chronic inflammation of the joints and tissue, rheumatoid arthritis (RA) is a painful and potentially disabling autoimmune disease.

New type of buckyball

Scientists at Rice University and Baylor College of Medicine have developed a new type of buckyball nanoparticle that acts as a passkey, allowing peptide-based drugs to enter cancer cells.

Molecular mechanism behind aggregation of amyloid beta peptide due to anesthetics

Inhaled anesthetics commonly used in surgery are more likely to cause the aggregation of Alzheimer's disease-related plaques in the brain than intravenous anesthetics say University of Pittsburgh School of Medicine researchers in a journal article published in Biochemistry.

Melanin concentrating hormone found to be involved with insulin production

A new Joslin Diabetes Center-led study has shown conclusively that a neuropeptide, melanin concentrating hormone (MCH), found in the brain and known for its role in increasing appetite in people, plays a role in the growth of insulin-producing beta cells and the secretion of insulin.

Targeting of cancer cells with ferrimagnetic ferritin cage nanoparticles

Researchers at Montana State University have used an engineered form of ferritin, a cage-like iron storage protein, to both synthesize and deliver iron oxide nanoparticles to tumors.

Biomimetic amplification of nanoparticle homing to tumors

A collaborative, multidisciplinary team of researchers has created nanoparticles that act much like a developing clot to target tumors.

Fibrinogen molecule structure acts as a molecular spring

Researchers at the University of Pennsylvania School of Medicine and the School of Arts and Sciences have shown that a well-known protein structure acts as a molecular spring, explaining one way that clots may stretch and bend under such physical stresses as blood flow.

Simple blood test for NT-proBNP level may help predict cardiovascular events

A blood test for patients with coronary heart disease could help predict their risk for subsequent cardiovascular events or death, according to a study in the January 10 issue of JAMA: The Journal of the American Medical Association.

In vivo biodistribution and highly efficient tumour targeting of carbon nanotubes in mice

In the first experiment of its kind, investigators at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (CCNE-TR), based at Stanford University, have shown that single-walled carbon nanotubes (SWCNTs) wrapped in poly(ethylene glycol), or PEG, can successfully target tumors in living animals.

High throughput quantification of protein expression of cancer antigens in tissue microarray using quantum dot nanocrystals

In attempt to identify biological markers, or biomarkers, that can signal the presence of cancer and help oncologists determine the best course of therapy when cancer is present, teams of investigators are scouring stored tissue samples obtained from thousands of cancer patients.
