Stem Cell Research Stem cell research is no longer a future unrealistic concept‚ it is here and having enormous impacts on the medical field. Stem cells are the primary cells that can be trained to develop into any human cell tissue such as muscle‚ skin‚ and brain. However‚ in embryonic stem cell research‚ to retrieve stem cells from embryos requires a process called therapeutic cloning where a person’s DNA is put into an unfertilized human egg (effectively cloning a person)‚ the embryo is then

The Human Egg Cell. The human egg cell is also known as the ovum. With a spherical structure it is the largest cell in the human body measuring about 0.2mm in diameter. The function of the ovum is to reproduce‚ when fertilized by the sperm cell the ovum is capable of creating a new living organism. The size and shape of the ovum gives it space to store and create nutrients (see fig 3) (Boyle and Senior 2008) The ovum is bounded by the egg follicles of the ovaries and is produced by primitive germ

TREATMENT OPTIONS There is NO cure for sickle cell disease‚ although new stem cell research is promising. Bone marrow transplant is a potential cure‚ however finding a matched sibling donor is difficult. Therefore treatment is primarily focused on management of symptoms and prevention of pain episodes. Hydroxyurea (a chemotherapeutic medication) is the only recognized treatment option for the prevention of vaso-occlusive crisis in SCD. It is a prescribed drug for adult patients

phone jammers transmits low power radio signals to cut off communications between cell phones and cell phone base stations. It does not interfere with any communications other than cellular phones with in defined regulated zone. Upon activating a cell phone jammer‚ all idle phones with indicate "no network". Imcoming calls are blocked as if the cellular hand phone were off. When the phone jammer turn off‚ all cell phones will automatically re-establish communications and rrovide full service.
