How Does One Get Lymphoma? | Health Tips

For one, despite the thousands of hours spent on medical research and laboratory testing the actual cause of the disease is still an unknown. DNA mutation is one of the plausible cause of why lymphoma develops but what happens why DNA have to mutate remains a big question to the medical science community. Medical scientists, nevertheless, have found several factors that trust possibly increase the risks of developing lymphoma. As you capability have already guessed, the two prevailing factors are genetic and environmental factors. Genetics for one is still a complicated issue that famously [more...]

Evaluation of Five Methods for Total DNA Extraction from Western ...

DNA extraction is a routine step in many insect molecular studies. A variety of methods have been used to isolate DNA molecules from insects, and many commercial kits are available. Extraction methods need to be evaluated for their efficiency, cost, and side effects such as DNA degradation during extraction. Methodology/Principal Findings From individual western corn rootworm beetles, Diabrotica virgifera virgifera, DNA extractions by the SDS method, CTAB method, DNAzol® reagent, Puregene® solutions and DNeasy® column were compared in terms of DNA quantity and quality, cost of materials, [more...]

DNA analysis of the soft tissue left behind on the engine took longer than normal and when the technician turned in the report, it listed the victim as a deer. Heacker immediately tracked down the pilot, and he confirmed the information he submitted. He was certain of the altitude of the collision. So the lab went back to work and solved the puzzle. It turned out that deer DNA was not the only type left behind on the engine. There was also black vulture DNA. Apparently, the unlucky victim was a vulture that had recently dined on a dead deer.

Vitamin B12 – Also known as cobalamin | Vitamin D Deficiency Symptoms

It is necessary during cell division for rapid DNA synthesis; especially in tissues where cell division occurs at a fast rate specifically bone marrow for the synthesis of red blood cells. Deficiency of B12 leads to production of Defective DNA bearing cells called megaloblast. This condition is called anemia. Symptoms are excessive tiredness, breathlessness, restlessness, pallor, and low immunity, sore tongue and menstrual disorder. B12 plays a major role in well being of nervous system. Nerves are surrounded by an insulating fatty sheath comprised of a complex protein called myelin. B12 is [more...]

The cancer holy grail: DNA test will allow doctors to create ...

The researchers at Johns Hopkins took six sets of cancerous and normal tissue from four bowel and two breast cancer patients and “sequenced” – or decoded – the complete set of DNA for each patient. By comparing DNA from healthy and cancerous tissue, the researchers could spot where large parts of genetic code had been altered. These changes occur only in cancer cells, making them ideal biomarkers for the disease. Once the researchers found areas where DNA had been rearranged, they looked for the same changes in DNA shed from tumours into the patients” blood. Using blood samples [more...]

Dog DNA - Finding Your Breed

There are several services, both online and in person, that can use specific information (the most accurate of which is a tissue sample containing dog DNA) to find out the exact history of your dog, including breed information, and which traits about your dog come from which breed. This can be used to determine a dog's temperament before you even adopt it, which can be a great way to make sure the dog will get along with your children or your other pets. Remember, certain types of dogs are better with certain things than others, and it never feels good to make a commitment to an animal that [more...]

DNA-Wrapped Carbon Nanotubes - Progress Toward Artificial Tissue?

Duplicating our organic tissue synthetically isn't as easy as it sounds.   Our bodily tissue is both soft and tough but modern implants - and replacement organs - will need to be as close to natural as possible to be effective. A team of Australian and Korean researchers led by Geoffrey M. Spinks and Seon Jeong Kim has now developed a novel, highly porous, sponge-like material whose mechanical properties closely resemble those of biological soft tissues.  It consists of a robust network of DNA strands and carbon nanotubes.  Soft tissues, such as tendons, muscles, arteries, and skin or [more...]

How DNA is Used in Paternity Testing?

Recently, companies have begun selling DNA paternity tests over the counter at drug stores, which facilitates home testing. However, results are usually inadmissible in court due to the chance of surreptitious DNA collection or false identification of the tested individuals. The legality of testing another person’s DNA without their consent varies by state. If a paternity test is to be used in a court of law, chain of custody of the DNA sample must be verified. This means that every step of the paternity testing process and analysis is documented, from the collection of the DNA sample by an [more...]

DNA Testing – Making the Right Choice

For a court to accept DNA test results as evidence of paternity, it is essential that the court can be certain that the correct procedures have been followed, right from the taking of the samples to the reporting of the results. The Ministry of Justice maintains a short list of companies who are accredited to carry out parentage tests directed by the civil courts in England and Wales under section 20 of the Family Law Reform Act 1969.

Muscle and liver biopsies were considered for respiratory chain studies, but because of hypocitrullinemia, molecular analysis for maternally inherited Leigh syndrome was first performed, revealing in both siblings the mitochondrial DNA T8993G mutation (95% heteroplasmy), allowing to avoid tissue biopsies. Hypocitrullinemia, an occasional finding in mitochondrial diseases, has been specifically associated with T8993G mutation. However, only few patients have been reported, and the prevalence of hypocitrullinemia in 8993 mitochondrial DNA mutations is unknown. In a small series of 16 Leigh [more...]

20000 Genes Under the Brain: Genes->Brain->Man

To assess gene expression in each small bit of tissue, researchers expose its RNA to a gene chip, or DNA microarray. These small devices are coated with clusters of identical DNA molecules, called probes, within separate areas. Each probe binds to the RNA of a specific gene—the one that contains a complementary set of chemical units, or bases. In a DNA molecule, the base adenine (A) sticks to thymine (T), and guanine (G) pairs with cytosine (C). Thus, the sequence that would bind to the strand illustrated above is (from top to bottom): T, C, C, T, G, C, A. In this way, a chip records which [more...]

A mutation in a DNA repair enzyme, for example, could increase error rates in the replication of a genome. Environmental factors are also a possibility, however, Conrad says that no one has yet identified specific culprits. X-rays and toxic chemicals affect DNA in so-called somatic cells, or adult tissue, rather than the germline cells that go on to form eggs and sperm. It's also not yet clear what the consequences of a highly variable mutation rate would be, though it's possible that families with higher rates would be more likely to have children with sporadic [more...]
