The study of epigenetic variability in cells and tissues could someday help diagnose diseases more precisely and provide more targeted treatments for chronic ailments. Details, summarized by Brown University researchers and others, are published online in the latest edition of PLoS Genetics.

ETT assessment is used to diagnose diseases, such as gastroesophageal reflux, dysphagia, esophagitis, and achalasia. These studies are commonly performed in conjunction with scintigraphic and manometric techniques, despite the use of ionizing radiation and catheters, for each of these additional techniques, respectively.

University of Utah scientists successfully created a sensitive prototype device that could test for dozens or even hundreds of diseases simultaneously by acting like a credit card-swipe machine to scan a card loaded with microscopic blood, saliva or urine samples.

Scientists are reporting development of a device that could serve as the electronic "reader" for a coming generation of "wellness cards," specimen holders used to diagnose disease from a drop of a patient's saliva or blood.

Researchers are on the verge of unleashing the power of the element boron in a new generation of drugs and therapies, as decades of research begins to bear fruit.

With unprecedented sensitivity, Carnegie Mellon University’s Mark Bier has characterized large viral particles and bulky von Willebrand factors using a novel mass spectrometer. These exciting results may lead to new biological discoveries and represent a step closer to rapid disease diagnosis using mass spectrometry.

Researchers from the University of Minnesota Medical School and Brain Sciences Center at the Minneapolis VA Medical Center have identified a noninvasive and painless way to diagnose complex brain diseases. And it’s as simple as staring at a point of light. The research offers promise for a less-stressful, painless, and objective diagnosis for brain diseases, as well as a way to measure the effectiveness of different treatments for these diseases.

Purdue University researchers worked with the Indiana University School of Medicine to establish a technique that provides a new approach for detecting a number of genetic disorders found in infants and young children.
