Telomerase Reactivation Reverses Tissue Degeneration in Aged Telomerase-deficient Mice Jaskelioff et al.‚ Nature‚ January 2011 This study looked at the effects of telomerase activation on the tissues of prematurely-aged adult mice. The telomerase enzyme‚ TERT-ER‚ is not expressed in the cells of these mice. The group induced (turned on) expression of TERT-ER by exposing mice to the compound 4-OHT‚ 4-hydroxytamoxifen (see definitions on next page). This treatment rebuilt the telomeres in

Diseases of the Muscular System There are over 650 muscles in the human muscular system. Each muscle has a specific role to perform. These muscles help us talk‚ walk‚ sit‚ run‚ eat‚ move about‚ hold things‚ and most important the continuous pumping of the heart muscles keeps us alive. Muscular system diseases cause many problems in the human body‚ that affects the mobility and functioning of various parts of the body. The list is very long as there are number of disorders that affect the human body

Wet Tissue Strength Tested on Various Tissue Brands Abstract: Wet tissue strength was tested on various tissue brands. The wet strength was shown by seeing how many marbles the wet tissue can hold. Students conducted this experiment to determine if higher priced tissues can hold an increased amount of marbles. This experiment was a blind study‚ with the supervisor of this investigation withholding information of which brand is which and their costs. At the end of this experiment‚ it was concluded

All of our body’s systems work together. One body system often times cannot work without the help of another system. The best example of systems working together is the skeletal system and the muscular system. Muscles are attached to bones; the muscles make the bones move. Without bones there is nothing to hold together the structure of muscles. Without both of these systems working together our body would be impossible to move on its own. The skeletal system is the system in our body that provides

The Respiratory System is crucial to every human being. Without it‚ we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs‚ by several cavities‚ tubes‚ and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the
