Fact 1: mRNA (messenger Ribonucleic Acid) is a molecule that instructs DNA (deoxyribonucleic acid) to make protein. In general, RNA cannot be incorporated into DNA readily. Human DNA is housed in the nucleus of the cell and is separate from the rest of the cell. Movement of molecules in and out of the nucleus is strictly controlled.

Current Method
Current methods of prostate cancer screening, such as prostate-specific antigen (PSA) tests and digital rectal exams (DRE), are somewhat unreliable and can lead to many uncertainties for both patient and urologist.

Like all types of dementia, Alzheimer's is
caused by brain cell death. It is a progressive neurodegenerative disease, which
means there is progressive brain cell death that happens over a course
of time. The total brain size shrinks with Alzheimer's - the tissue has
progressively fewer nerve cells and connections.

Conventional Method
Current conventional method for cataract surgery involves making a small incision in the cornea, followed by an incision in the front of the capsule of the lens also called a capsulotomy. The procedure opens up the capsule and through an ultrasound probe inserted with high frequency sound energy, the lens is fragmented in situ. This process is called phacoemulsification.
