DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Loop-mediated Isothermal Amplification test for human African trypanosomiasis

The Geneva-based not-for-profit foundation FIND and Japanese diagnostics company Eiken announced today that a next-generation molecular test designed specifically for sleeping sickness - a deadly parasitic disease also known as human African trypanosomiasis (HAT) - is ready to enter accelerated field trials in sites across the Democratic Republic of Congo and Uganda.

New nanopore sensor can lead to early detection of lung cancer

When lung cancer strikes, it often spreads silently into more advanced stages before being detected. In a new article published in Nature Nanotechnology, biological engineers and medical scientists at the University of Missouri reveal how their discovery could provide a much earlier warning signal.

Fast-track genetic diagnosis for hearing loss

Over 28 million Americans are hearing impaired, and 50 percent of these cases can be traced to genetic causes. The condition can be especially challenging for children born hearing impaired because spoken language, reading, and cognitive development are tied to hearing. That makes early diagnosis essential for identifying appropriate therapy and treatment.

Psychological stress of racial discrimination may contribute to health disparities

The consequences of psychological stress, resulting from racial discrimination, may contribute to racial health disparities in conditions such as cardiovascular disease, diabetes and other age-associated diseases.

OXTR gene associated with optimism, self-esteem and mastery

UCLA life scientists have identified for the first time a particlular gene's link to optimism, self-esteem and "mastery," the belief that one has control over one's own life - three critical psychological resources for coping well with stress and depression.

Researchers evaluate effect of Terahertz radiation on gene expression in stem cells

Terahertz technologies show promise for myriad medical, military, security, and research applications ranging from the detection of cancer to airport security systems to shipment inspection to spectroscopy. Relatively little is known, however, about the effect of THz radiation on biological systems.

BVES protein may play a role in colon cancer progression

A protein critical in heart development may also play a part in colon cancer progression. Research led by investigators from Vanderbilt-Ingram Cancer Center and the Vanderbilt Eye Institute suggests that the protein BVES (blood vessel endocardial substance) - which also is key in regulating corneal cells - may be a therapeutic target for halting colon cancer metastasis.

Research identifies 6 critical deafness-related mutations in Israeli Jewish, Palestinian Arab families

Precise diagnosis of disease and developmental syndromes often depends on understanding the genetics underlying them. Most cases of early onset hearing loss are genetic in origin but there are many different forms. Heretofore, it has been difficult to identify the gene responsible for the hearing loss of each affected child, because the critical mutations differ among countries and populations.

Scientists successfully disrupt function of MYC cancer gene

Dana-Farber Cancer Institute scientists have successfully disrupted the function of a cancer gene involved in the formation of most human tumors by tampering with the gene's "on" switch and growth signals, rather than targeting the gene itself.

Preliminary research shows how Fusarium microbes travel through the air

Preliminary research on Fusarium, a group of fungi that includes devastating pathogens of plants and animals, shows how these microbes travel through the air. Researchers now believe that with improvements on this preliminary research, there will be a better understanding about crop security, disease spread, and climate change.

Common genetic variant may predispose people to acute dissections

Richard Holbrooke, John Ritter, Lucille Ball, Jonathan Larson and Great Britain's King George II were all taken by the same silent killer: an acute aortic dissection. Now, scientists led by researchers at The University of Texas Health Science Center at Houston and Baylor College of Medicine have found an association with a common genetic variant in the population that predisposes people to acute dissections and can approximately double a person's chances of having the disease.
