Hip Replacement Can Now Be Performed On Virtual Patients

...s perform hip replacement surgeries// on a virtual copy of their real patient. This would greatly improve the treatment outcome for patients for whom it surgery is necessary. Several techniques involving virtual reality, tissue profiling and stereoscopic vision have been culminated to create virtual pat...

Down syndrome simulated in animal model after successful chromosome transplantation

...hromosome 21 into mice. The presence of an extra copy of the 21st chromosome is responsible for Down syndrome, one of the most common autosomal chromosomal disorder. This move is anticipated to transform medical research into genetic causes of the disease. Down's syndrome occurs in one in about every 8...

Short Stature Can Be Treated With A New, Non-Growth Hormone In Future

...r-1 (IGF-1). Increlex is a genetically engineered copy of IGF-1. The purified protein has been shown to be structurally and functionally identical to natural human IGF-1. It is injected daily before a meal to provide the catalyst the body needs to grow. Ongoing clinical trails would be directed towards ...

Risk of colon cancer to be assessed by simple blood test

...of protein production proteins on which parent the copy came from. For IGF-2, only the gene copy inherited from the father should be turned on, and that from the mother should be off. In about five...

Genetic Expressions Can Influence The Process Of Aging

...ensive studies of mice that are born with only one copy of the gene. Still, these animals die at a young age. So to study p63 function in adults, Mills and her colleagues devised a sophisticated molecular genetic technique that enabled them to eliminate both copies of the gene from particular tissues incl...

Genetic failure in cloned animals

...l into an egg cell and creating a relatively exact copy of that animal -- does not adequately reprogram the genes for proper development. In other words, the cloned animals showed genetic defects because the procedure does not replicate normal reproduction, Jaenisch said, although it is not yet understood...

Xenotransplantation “breakthrough”

...e sheep, used gene targeting to knock out a single copy of alpha 1,3 galactosyl transferase. Nuclear transfer was then used to create the five piglets.The first use of the new technology is likely to involve the production of islet cells for the treatment of diabetes. Such cells will be transplanted into ...

Fat Cell Protein Hits Type-2 Diabetes

...d a genetic approach in cells to generate an exact copy of the Acrp30 protein. They injected mice with Acrp30 until they doubled the protein level. The question was that iIf we simply doubled the concentration of this adipose-derived hormone and then carefully measure the hepatic glucose production -- or...

Fight oral cancer with gene therapy mouthwash

...novirus, a kind of cold virus, that lack a working copy of one gene that ordinarily allows that virus to infect cells with good p53 genes, it should infect only cells with damages p53 genes. In theory, at least, the crippled virus will enter precancerous cells and kill them. So far this breakthrou...

Possibility Of Treatment For Permanent Hearing Loss

...alled dominant negative mechanism -- when a single copy of the mutant gene is sufficient to cause disease because the protein from the faulty gene has a dominant adverse effect over the protein from the normal gene. Several human forms of inherited deafness, including the one mimicked by the UI mouse mode...

Genes from saliva may predict oral and breast cancer

...A) from saliva and blood serum. The mRNA carries a copy of the cells’ genetic code from the cell’s DNA, with the help of an enzyme called RNA polymerase. This process is known as transcription and the products are the transcripts. The researchers had collected saliva and blood from 32 patients suffering ...

Gene increases risk of depression after stress

...ob or a loved one. People only have to inherit one copy of the gene, from either parent, to become more vulnerable to depression, the researchers in Britain, New Zealand and the United States found. Stress events, such as divorce or illness, are well-known triggers for depression--one of the five leading ...

Y chromosome uses trick to repair its own genes

... copies of its important genes, and it can use one copy to fix a flaw in the other. The gene-fixing technique comes at a price. When the chromosome makes a mistake in the procedure, it can delete stretches of DNA. Such deletions, occuring in one in every couple thousand boys, are a recognized cause of m...

Mutating viruses helps produce antibodies

Stem Cells Have Few Mutations

...etion of a chromosome that is replaced by a second copy of the remaining chromosome. Although the numerical balance of chromosomes is restored by the replacement, the mutation can increase the risk of tumor formation. But this type of mutation is quickly spotted in routine laboratory screening of cells,...

Down syndrome life anticipation doubles

...r lifestyle." Down syndrome is caused by an extra copy of chromosome 21 and occurs in one in every 600 babies throughout the world. It is one of the most common known causes of intellectual disability. "Figures on the survival rate of people with Down syndrome are important to us as families but it's als...

Pig cloning for organs

Inherited gene important in ovarian cancer

...the father, one from the mother. It only takes one copy of BRCA1 to be lost for cancer protection to be reduced. It's possible for genes to be lost due to a malfunctioning when cells divide - this can happen even if you inherit two normal copies. The study shows that BRCA1 is more significant in ovarian...
