The human body shows its ability to heal itself when injured. However‚ the human body is not the only living thing that has a way of healing with no help. Planaria‚ which are free-living flatworms‚ are known for their quick regeneration from a fraction of the body. Scientists have been studying planaria and the effects of magnetism on the regeneration rate of the planaria. The hypothesis of this experiment is that if the planarians are exposed to a certain number of magnets at a closer distance‚

Summary: This paper explores the scientific and ethical considerations of DNA testing in prenatal testing (PT).Taking into consideration non-invasive and invasive sampling and the ethical issues DNA testing raises. Cell-free fetal DNA (CffDNA) in prenatal screening which considers being a recent non-invasive technique. This non-invasive diagnostic test believes to be much safer and can be performed in early pregnancy easily comparing to invasive diagnostic testing. However‚ CffDNA has flows such

skeletal system. Endochondral ossification is the process through which the axial and appendicular skeletons are formed through the formation of a cartilage inter-mediate. A good model for endochondral ossification is the limb bud where the precursor cells of the mesenchyme condense and then followed by the differentiation of the most central chondrocytes. Endochondral ossification is a highly regulated process by different signalling like the epidermal growth factor receptor (EGFR)‚ a tyrosine kinase

and their teachings. Perhaps the most divisive categories of genetic research include embryonic and stem cell research‚ as well as prenatal screening and diagnosis. Stem cell research is an unending controversial issue. Many people do not know exactly what stem cell research is‚ or how it could affect the lives of many people around the world. Most people are also oblivious to what stem cells actually are and where they come from as well as their uses in the human body. As far as prenatal screening

is a succession of mitotic cell divisions without cell growth between division cycles. There is close to no cell growth because during cleavage‚ the embryonic cells undergo the S and M phases of the cell cycle but practically avoid the G1 and G2 phases. Thus‚ the embryo does not increase in cytoplasmic material or enlarge but merely partitions its zygote into smaller blastomeres. The first five to seven divisions produce a

Embryonic Cloning Embryo cloning is an area of stem-cell research that focuses on embryos and is the process of harvesting human stem cells for scientific study. Embryonic stem-cell research is sometimes also referred to as research cloning and therapeutic cloning. Cloning is a general term that scientists use to describe various processes for duplicating biological organisms and is an ethically controversial area of biomedical research. The debate regarding cloning is centered mainly around the

When the public questioned the use of immunotherapy‚ researchers explained‚ “In 2013‚ cancer immunotherapy was named ‘breakthrough of the year’” breaking expectations in clinical testing.

At this stage nothing can be done to prevent or cure type 1 diabetes. Which cells stop working properly? Insulin is a hormone produced in the pancreas by special cells‚ called beta cells.

What Is Stem Cell? A stem cell is an undifferentiated cell that has the potential to develop into many different cell types in the body during early life and growth. However‚ stem cells are distinguished from other cell types due to the following reasons: (1) They are unspecialized cells capable of renewing themselves through infinite cell division‚ even after long periods of inactivity‚ (2) They can be induced into becoming a tissue- or organ specific cells with special function‚ such as muscle
