Functional magnetic resonance imaging reveals brain circuitry associated with social status

Human imaging studies have for the first time identified brain circuitry associated with social status, according to researchers at the National Institute of Mental Health (NIMH) of the National Institutes of Health.

A stem cell type supposed to be crucial for angiogenesis and cancer growth does not exist?

It is widely believed that tumor angiogenesis and cancer growth critically depend on circulating endothelial precursor cells, mobilized from the bone marrow. The recent study from researchers at the University of Helsinki, Finland, and Stanford University, US, now suggests that a stem cell type supposed to be crucial for blood vessel formation and cancer growth does not actually exist.

Cancer could return unless stored ovarian tissue undergoes adequate testing before re-implantation

Cancer patients who have been successfully treated for their disease face the prospect of its return if stored ovarian (or testicular) tissue is transplanted back into their bodies without adequate checks, according to researchers at two university hospitals in Israel.

Skin lesions larger than 6 millimeters more likely to be melanomas

Skin lesions larger than 6 millimeters in diameter appear more likely to be melanomas than smaller lesions, according to a report in the April issue of Archives of Dermatology. The findings suggest that the diameter guidelines currently used by dermatologists to screen for melanoma are useful.

Neuroimaging helps improve quality of life for brain tumor patients

A new neuroimaging study at the Montreal Neurological Institute and Hospital at McGill University aims to ensure the highest quality of life for patients by assessing their cognitive skills before, during, and after brain tumour surgery. This is done by mapping the important functional brain areas surrounding the tumour in order to decrease the risks during surgery.

Experimental study on most common form of heart valve disease in Western countries may lead to new treatments

A team of scientists from the University of Montreal and the Montreal Heart Institute Research Centre, led by Dr. Jean-Claude Tardif, has completed an important study that show how a new type of medication can lead to an improvement in the aortic valve narrowing

Fluorine-based nanoparticles on track to improve cancer detection and therapy

Perfluorocarbons, a class of inert, oily polymers, have a proven track record in a variety of clinical uses, including in contrast-enhanced ultrasound imaging and in eye surgery to correct a detached retina.

Nanoparticles provide detailed view inside living animals

Using nanoparticles designed specifically to produce a bright Raman spectroscopic signal, a team of investigators at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response (Stanford CCNE) has shown that it can produce whole-body images in small animals that can reveal the location of tumors and track how these nanoparticles traffic through the body.

Quantum rods light up pancreatic cancer cells

Quantum dots have shown promise as ultrabright contrast agents for use in a variety of cancer imaging studies. Now, a team of investigators at the Multifunctional Nanoparticles in Diagnosis and Therapy of Pancreatic Cancer Platform Partnership, headed by Paras Prasad, Ph.D., of the State University of New York at Buffalo, has shown that quantum rods may perform even better than their spherical cousins.

Iron nanoparticles spot tumor spread in patients with kidney cancer

Iron nanoparticles designed to collect in lymph nodes containing metastatic cancer cells have proven that they can help physicians detect metastatic spread of prostate cancer.

Novel polymers inhibit nonspecific protein absorption

One problem that confounds researchers who are developing nanoparticles for use as cancer imaging and therapeutic agents is that many nanoparticles accumulate blood proteins on their surfaces as they circulate through the body.

Life Sciences Discovery Fund awards $2.2 million to support new solid-tumor research program

The state's Life Sciences Discovery fund has awarded $2.2 million to establish a formal phase 1 clinical-trials program to test new therapies for solid tumors at Fred Hutchinson Cancer Research Center. Announced this evening, the grant is among the first funded by Washington's $350 million tobacco-lawsuit-settlement bonus.

Measurement technology to investigate neurovascular coupling

Every two minutes in Germany, one person suffers a stroke. About one third of the affected do not survive the sudden lack of blood in the brain, many others are left with serious disabilities.

New drug for melanoma riluzole shows promise

Rutgers Professor Suzie Chen has found that riluzole, a U.S. Food and Drug Administration (FDA) approved drug used to treat Lou Gehrig's disease (ALS), slows the growth of melanoma, the most aggressive form of malignant skin cancer.

Elevated levels of antioxidant urate may slow Parkinson's progression

Naturally elevated levels of the antioxidant urate may slow the progression of Parkinson's disease in men. Researchers from the MassGeneral Institute for Neurodegenerative Disease (MGH-MIND) and Harvard School of Public Health (HSPH) examined data from an earlier study and found that, among recently diagnosed Parkinson's patients, those with the highest urate levels had a significantly slower rate of disease progression during the two-year study period.

Patient's exposure to radiation significantly lower when using prospective gated 64-channel cardiac CT

A new cardiac CT technique, prospective gated 64-channel cardiac CT, has a significantly lower radiation dose and produces CT coronary angiograms with better image quality when compared with the standard retrospective ECG gating, according to a recent study conducted by researchers at the University of Washington in Redmond, WA.
