Discovery may have implications for many diseasesCells are the building blocks of the human body. They are a focus of scientific study, because when things go wrong at the cellular and molecular level the consequences for human health are often significant.A new finding based on multiple collaborations between UNC and Duke scientists over several years points to new avenues for investigation of cell metabolism that may provide insights into diseases ranging from neurodegenerative disorders...
Stress protection: How blue-green algae hoard energyUnder normal conditions, cyanobacteria, also termed blue-green algae, build up energy reserves that allow them to survive under stress such as long periods of darkness. They do this by means of a molecular switch in an enzyme. By removing this switch, it should be possible to use the excess energy of the bacteria for biotechnological purposes such as hydrogen production, without the bacteria suffering. This was found out by researchers at...
Cell's power generator depends on long-sought proteinMitochondria, those battery-pack organelles that fuel the energy of almost every living cell, have an insatiable appetite for calcium. Whether in a dish or a living organism, the mitochondria of most organisms eagerly absorb this chemical compound. Because calcium levels link to many essential biological processes"”not to mention conditions such as neurological disease and diabetes"”scientists have been working for half a century to...
OMAHA, Neb., June 16, 2011 /PRNewswire/ -- Transgenomic, Inc. (OTC/BB: TBIO) today announced the launch of the Nuclear Mitome Test, a genetic test to aid physicians in the diagnosis of mitochondrial disorders. The Nuclear Mitome Test, employs next-generation sequencing technology to identify mutations in more than 400 genes, and represents the most comprehensive genetic test available for mitochondrial disorders. The announcement was made at the 2011 United Mitochondrial Disease Foundation...
Two promising new treatments to aid people with autism have shown effectiveness in pilot studies conducted by an Arizona State University professor and private researchers.Several studies indicate that children with autism often have abnormalities in critical biochemical functions that help maintain health "“ specifically methylation, glutathione, and mitochondrial functions.Methylation turns proteins in the body on and off "“ including DNA and RNA "“ a function that controls gene...
Midbrook Medical, the Jackson, MI, manufacturer of medical decontamination, sterilization systems and custom fabricated medical equipment has introduced the "Medicount" Adenosine Triphosphate (ATP) testing system to aid healthcare facilities in the fight against Healthcare associated infections (HAIs). (PRWEB) May 28, 2011 Midbrook Medical, the Jackson, MI, manufacturer of medical decontamination, sterilization systems and custom fabricated medical equipment has introduced the...
--Children's Hospital of Philadelphia Study May Point to Much-Needed Drug Therapy for Elusive Metabolic Disorders -- PHILADELPHIA, May 19, 2011 /PRNewswire-USNewswire/ -- A human drug that both prevents and cures kidney failure in mice sheds light on disabling human mitochondrial disorders, and may represent a potential treatment in people with such illnesses. "There are no effective cures for mitochondrial diseases, even in animals," said study leader Marni J. Falk, M.D., who cares for...
Around one in 20 men is infertile, but despite the best efforts of scientists, in many cases the underlying causes of infertility have remained a mystery. New findings by a team of Australian and Swedish researchers, however, will go a long way towards explaining this mystery.According to their research published in Science today, a small set of genes located within the power-plants of our cells "“ the mitochondria "“ are crucial to unravelling the secrets of male infertility.Most of our...
Mitochondria are the body's energy producers, the power stations inside our cells. Researchers at the University of Gothenburg, Sweden, have now identified a group of mitochondrial proteins, the absence of which allows other protein groups to stabilise the genome. This could delay the onset of age-related diseases and increase lifespan.Some theories of human ageing suggest that the power generators of the cell, the mitochondria, play a part in the process. In addition to supplying us with...
Scientists have discovered a new component of mitochondria that plays a key part in their function. The discovery, which is presented in the journal Cell Metabolism, is of potential significance to our understanding of both inherited and age-related diseases.Mitochondria are normally called the cell's power plants since they convert the energy in our food into a form that the body can use. To work properly, the mitochondria have to form new proteins, which they do in their ribosomes.A group...
