Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter.

Mushrooms are a great source of antioxidants

Using a new, more sensitive-testing approach they developed for fungi, Penn State food scientists have found that mushrooms are a better natural source of the antioxidant ergothioneine than either of the two dietary sources previously believed to be best

Fluorescence spectroscopy able to detect the presence of inflammatory cells that are associated with critical atherosclerotic plaques

Because atherosclerotic plaque typically builds up without symptoms and leads to more than 1 million deaths in America each year, the search is on to develop early detection devices that will enable physicians to offer treatment before the disease progresses to advanced stages.

Researchers reveal secret of key protein in brain and heart function

Brown University biologists have solved the structure of a critical piece of synapse-associated protein 97 (SAP97) found in abundance in the heart and head, where it is believed to play a role in everything from cardiac contractions to memory creation. Results are published in The Journal of Biological Chemistry.

New way to prevent macular degeneration

Two studies from an unusual research partnership at the University of Chicago appear to have resolved a long-standing dispute about the role of melanin in the eye. The studies, one published in the Proceedings of the National Academy of Sciences (PNAS) and one early online in the Journal of the American Chemical Society (JACS), also suggest a new way to prevent a common cause of blindness.

Adding spectroscopy to breast MR examinations may improve the efficiency and quality of patient care

Measuring the biochemical changes in breast tumors with magnetic resonance (MR) spectroscopy enables radiologists to more accurately distinguish benign tumors from cancerous ones, according to a study appearing in the August issue of the journal Radiology.

New insights into brain cell metabolism from PET and MRI scans

By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) test.

Forensic use of tandem mass-spectroscopy detects links between banknotes and drugs

Research published in this month’s edition of the journal Rapid Communications in Mass Spectrometry, describes a method that can detect a pattern of contamination on banknotes from drug related crime that is different from the pattern seen in general circulation. The process is significantly faster than other previous methods.

Brain differences in bipolar disorder shown in MRI

Experts in the U.S., in an attempt to define the abnormalities in the brains of people with bipolar disorder, have used used functional MRI to measure levels of metabolic activity in different areas of the brain.

Studies show Alzheimer's prevented by drinking juice daily and having the occasional alcoholic drink

At a conference in the U.S. on Alzheimer's disease on June 19, researchers said that they think brain scans and simple blood tests may offer the best ways to predict who has the highest risk of Alzheimer's disease.

The bacteria that cause food poisoning, bubonic plague, and whooping cough all deploy the same weapon to infect the body

A molecular "syringe" sticks out of the bacteria, pokes a hole in a nearby cell, and squirts in venomous proteins that hijack the cell's machinery.

Fluorescence device to diagnose atherosclerosis and tumors

In a presentation at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center's Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.

Severely obese children have lipoprotein profiles that signal early risk of cardiovascular disease and the metabolic syndrome

"The message is urgent about the importance of prevention of cardiovascular disease in childhood. Lifestyle modification with appropriate diet and exercise can reduce cardiovascular risk in children," said lead author Daniel L. Preud'Homme, M.D., associate professor of medicine at the Wright State University School of Medicine and director of the lipid clinic at The Children's Medical Center, both in Dayton, Ohio.

Genomics and proteomics to increase the efficiency of drug discovery and development

While the United Sates is still the world leader, Europe is having a good deal of success in the field of advanced genomics and proteomics research. Significant government funding together with the presence of large pharmaceutical companies has made Europe a major competitor in the efforts to deploy genomics and proteomics as vital tools in drug discovery and development.

Brain region recovery possible in former methamphetamine users

Adaptive changes in chemical activity in certain regions of the brain of former methamphetamine users who have not used the drug for a year or more suggest some recovery of neuronal structure and function, according to an article in the April issue of Archives of General Psychiatry.

Telomerase finding has major implications for cancer

UCLA biochemists have determined the three-dimensional structure of a major domain of telomerase, the enzyme that helps maintain telomeres - small pieces of DNA on the ends of chromosomes that act as protective caps - allowing DNA ends to be copied completely when cells are replicated.

Commonly used anesthetic regimen appears to have no negative effects on the developing brain of the fetus

An anesthetic regimen commonly used during surgery on pregnant mothers appears to have no negative effects on the developing brain of the fetus, according to a new study on sheep conducted by Duke University Medical Center researchers.

Common anesthetics appear safe for developing fetal brain

A group of Dartmouth researchers has learned that the brain's auditory cortex, the part that handles information from your ears, holds on to musical memories.

Special imaging study shows failing hearts are energy starved

Using magnetic resonance spectroscopy (MRS) for the first time to examine energy production biochemistry in a beating human heart, Johns Hopkins researchers have found substantial energy deficits in failing hearts.
