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).

Mitomics introduces new test to detect prostate cancer

Mitomics, world leader in the research and development of mitochondrial genome-based products to improve clinical insight and therapeutic decisions, announced today the launch of its flagship product, the Prostate Core Mitomic Test, a revolutionary new test that uses the science of mitochondrial DNA to accurately determine the absence or presence of cancerous cells using previously obtained prostate biopsy tissue.

Sequential treatment with Entecavir and Lamivudine results in rebound of hepatitis B virus

A two-year trial of entecavir followed by lamivudine (LAM) in patients with chronic hepatitis B virus (HBV) infection resulted in a virologic rebound rate of 24% and 12% drug-resistance rate. Patients who continued on entecavir therapy throughout the study period had undetectable HBV DNA at the two-year endpoint. Details of this trial are published in the April issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases..

Immune therapy can control fertility in mammals

Researchers at Weill Cornell Medical College have shown that it is possible to immunize mammals to control fertility. They say their technique could possibly be used on other mammals -- including humans -- because fertility hormones and their receptors are species-non-specific and are similar in both females and males. For pets, the technique could be an alternative to castration and adverse effects of hormone administration.

New schizophrenia research reveals difference in identical twins genetic makeup

Just like snowflakes, no two people are alike, even if they're identical twins according to new genetic research from The University of Western Ontario. Molecular geneticist Shiva Singh has been working with psychiatrist Dr. Richard O'Reilly to determine the genetic sequencing of schizophrenia using identical or monozygotic twins. The study is published in this month's PLoS ONE.
