A new century of Alzheimer's disease research

...s in white matter and hints of vascular damage; MR spectroscopy to assess chemical processing; functional MRI to look at the brain’s reaction to stimulus; positron emission tomography (PET) and glucose PET scanning to examine the functional aspects of performance; and the newest modality, amyloid imaging, which c...

Study Finds Abdominal Fat Not the Prime Cause for Metabolic Syndrome

...in carbohydrates, and turned to magnetic resonance spectroscopy to measure the production of liver and muscle triglyceride, the storage form of fat, glycogen, and carbohydrate. The study found that in the insulin resistant subjects, the energy obtained from their carbohydrate rich meals was rerouted to liver tr...

Simple Chemical Reaction may Help Early Disease Diagnosis

...s when detected through nuclear magnetic resonance spectroscopy equipment. The study was conducted by a team of researchers led by Daniel Raftery and Bryan Hainline at Purdue University and Indiana University School of Medicine. As part of the study, researchers used a method of analysis, called metabolomics,...

Scientists Saying Against Trees Sparks Debate

...f light (12CH4) methane in the air. Photo-acoustic spectroscopy (a laser-based measuring technique) was used to detect the gas. Dueck said it showed that even a large mass of plants produced negligible methane emissions - at most 0.3 percent of Keppler's values. So if Dueck's team is correct, where did Kepple...

Decoding Protein Structures Helps Illuminate Cause of Diabetes

New Analytical Tool to Unravel the Cause of Diabetes

..., used a method, known as two-dimensional infrared spectroscopy (2-D IR for short), that takes advantage of the restless nature of molecules and atoms to break down this dynamic process. They obtained a single structural scan of hIAPP in less than a second - more than 500 times faster than previously possible....

Adolescents Brains Fully Develop Between 10-12 Years

...uctural brain imaging with MRI, magnetic resonance spectroscopy (MRS), and diffusion tensor imaging (DTI) to study the development of different brain structures and the creation of connections between them, and even changes in brain chemistry. The final goals of the project are to offer a plan of the developmen...

Yoga Helps to Combat Depression, Anxiety

...he GABA levels was done using a magnetic resonance spectroscopy technique developed by J. Eric Jensen, PhD, an assistant professor of psychiatry at Harvard Medical School and an associate physicist at McLean Hospital. According to the researchers, yoga has shown promise in improving symptoms associated with dep...

Natural Antibiotics Yield Secrets to Atom-level Imaging Technique

Simple Breath Test may Detect Lung Cancer

...itive machines such as gas chromatography and mass spectroscopy to "read" the volatile organic compounds coming from diseased lungs. But the machines are expensive to use and require specially trained experts to interpret the results. In comparison, the color sensor is cheap and easy to read, according to the...

Dermatologists Provide Unique Evidence of Possible Cause of Rare Skin Condition

...ctron microscope equipped with electron dispersion spectroscopy to search the tissue for metals. They also were blinded as to which blocks of tissue were from NSF/NFD cases and which were from negative controls. The study found that gadolinium was detected in four of 13 tissue specimens from patients with NSF/N...

Nanotechnology Used For Detecting Viruses

...ripp explained that previous attempts to use Raman spectroscopy to diagnose viruses failed because the signal produced is inherently weak. But UGA physics professor Yiping Zhao and UGA chemistry professor Richard Dluhy experimented with several different metals and methods and found a way to significantly ampli...

The Anti-HIV Properties Of Green Tea Uncovered

...dy the researchers used nuclear magnetic resonance spectroscopy to see what EGCG does to prevent HIV infection from progressing. " "One of the promising factors is, that because this is a small molecule and binds to the same exact binding pocket as (HIV's) gp120, it may not inhibit the (normal) function of the ...

A Major Break Through in Treatment for Metabolic Syndrome

...protein, testing many different sections using NMR spectroscopy to eventually find the KIX area--just one tenth the area of the larger ARC105 protein--that specifically binds to SREBP. This specific interaction between SREBP and ARC105 might be a target for small molecule drugs, according to Dr. Wagner. "While ...

Experiments In Outer Space To Determine single Cell Survival

...urface. These may enhance the sensitivity of Raman spectroscopy for monitoring the onset of infection or the course of therapy. The cells also localize proteins at the cellular interface. Assistant Professor Graham Timmins of UNM's College of Pharmacy notes that the encapsulated cells' unusual longevity may ser...

Heart disease and strokes connected to a motor protein mechanism

...orkers to observe how proteins work in motion. NMR spectroscopy exploits the interaction of radio waves with matter to give scientists a moving picture of molecular structures within the body. The methodology used in Kalodimos group provides researchers with detailed, moving pictures rather than static images pro...

Preterm Babies Benefited from a New NI Spectroscopy

...nd at the baby's bedside. ‘Our new near-infrared spectroscopy is a huge advantage for our research. As blood pressure is a constantly-changing, dynamic process, it is vital for us to be able to monitor the changes in brain oxygen levels continuously. With the machine we were using up until now, there was a high...

New Test to Diagnose the Peripheral Arterial Disease (PAD)

... a special push-pedal machine in an MRI scanner. A spectroscopy coil in the MRI then took readings of the phosphocreatine level in the legs every 15 seconds for several minutes afterward. 'If the blood flow is poor,' Kramer explained, 'PCr recovery is slow, because the muscle is not getting the energy sources it ...

Caffeine Content In Beverages To Be Identified By Home Test Kit
