Noninvasive treatment of cancer tumors

Ram Devireddy, assistant professor of mechanical engineering at LSU, recently co-authored an article with Todd Monroe, assistant professor of biological and agricultural engineering, investigating the complex effects of nanoparticles on cell freezing.

Researchers clarify alphaB-crystallin's role in multiple sclerosis

A protein found primarily in the lens of the eye could be the critical "tipping point" in the spiral of inflammation and damage that occurs in multiple sclerosis, researchers at the Stanford University School of Medicine report.

New area of stroke drug discovery for the 22nd century

A new therapy to re-activate silenced genes in patients who suffer from neurodegenerative diseases or stroke is being developed by researchers at the University of Illinois at Chicago and Cornell University.

New understanding of how Staphylococcus aureus hides

A major cause of human and animal infections, Staphylococcus aureus bacteria may evade the immune system" defences and dodge antibiotics by climbing into our cells and then lying low to avoid detection.

Stress and Alzheimer's disease

Subjecting mice to repeated emotional stress, the kind we experience in everyday life, may contribute to the accumulation of neurofibrillary tangles, one of the hallmarks of Alzheimer's disease, report researchers at the Salk Institute for Biological Studies.

Breakdown of myelin may be the cause of Huntington's disease

Last month, Dr. George Bartzokis, director of the UCLA Memory Disorders and Alzheimer's Disease Clinic, suggested in the journal Alzheimer's & Dementia that the breakdown of a type of myelin that develops late in life promotes the buildup of toxic amyloid plaques long associated with Alzheimer's disease.

Researchers find new mechanism of action of the anti-cancer drug sorafenib

Virginia Commonwealth University Massey Cancer Center researchers have uncovered a new mechanism of action of the anti-cancer drug sorafenib, which could stimulate the development of novel regimens in which it is combined with other molecularly targeted agents for patients with blood cancers and solid tumors.

Nanoparticle-enabled peptide delivery triggers tumor regression

Cells possess a variety of ways of dealing with mutations that can cause them to grow uncontrollably and eventually form a tumor. The tumor suppressor gene p53 plays a critical role in these cancer prevention processes, largely by triggering a form a cell death known as apoptosis.

Double-duty nanoparticles overcome drug resistance in tumors

Cancer cells, like bacteria, can develop resistance to drug therapy. In fact, research suggests strongly that multidrug resistant cancer cells that remain alive after chemotherapy are responsible for the reappearance of tumors and the poor prognosis for patients whose cancer recurs.

Newly found antibodies may be body's natural defense against Alzheimer's

In an important advance in the battle against Alzheimer's disease, physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center have identified naturally occurring antibodies in human blood that may help to defend against this form of dementia as well as other neurodegenerative diseases.

Cholesterol causes changes in gene expression

Experts from the University of Granada carried out research on atherosclerosis from its earliest stages to discover the origin of atheromatous plaques, fatty deposits gradually and irregularly formed in the main arteries, causing the narrowing of the blood vessel.

New drug-delivery system using nanomaterials

Researchers at UCLA have successfully manipulated nanomaterials to create a new drug-delivery system that promises to solve the challenge of the poor water solubility of today's most promising anticancer drugs and thereby increase their effectiveness.

Researchers discover how strokes trigger biochemical events that increase amyloid-beta production in the brain

Researchers from the MassGeneral Institute for Neurodegenerative Disorders (MGH-MIND) have discovered how the death of brain cells caused by a stroke or head injury may cause generation of amyloid-beta protein ? the key component of senile plaques seen in the brains of patients with Alzheimer's disease.

Combination therapy reduces tumor resistance to radiation

Radiation is used to treat a variety of tumors and the response of tumors to radiation is dependent on endothelial cell death, which in turn limits oxygen delivery to the tumor, causing hypoxia and tumor cell death.

Vorinostat shows anti-cancer activity in recurrent gliomas

North Central Cancer Treatment Group (NCCTG) researchers, based at Mayo Clinic in Rochester, Minn., report that a novel application of the drug vorinostat shows activity in patients with recurrent glioblastoma multiforme.

Percutaneous ethanol injection helps manage bone metastasis in thyroid cancer patients

Percutaneous ethanol injection (PEI), an injection of ethanol (alcohol) through the skin directly into a bone tumor to kill cancer cells, may be a valuable ancillary treatment for thyroid cancer patients whose cancer has spread to the bone.

CRT and Manchester University announce biomarker alliance with AstraZeneca

Cancer Research Technology Limited (CRT), the cancer-focused development and commercialisation company, and The University of Manchester today announce the establishment of an alliance with AstraZeneca to develop serological pharmacodynamic (PD) biomarkers.

Insights into a key strategy cancer cells use to survive and thrive

The discovery of how some abnormal cells can avoid a biochemical program of self-destruction by increasing their energy level and repairing the damage, is giving investigators at St. Jude Children's Research Hospital insights into a key strategy cancer cells use to survive and thrive.

Discovery of inherited gene mutation for leukemia

Researchers have discovered the first inherited gene mutation that increases a person's risk for chronic lymphocytic leukemia (CLL), one of the most common forms of the disease.
