Muscular dystrophy (MD) can be described as a group of diseases that cause continuing weakness and loss of muscle mass. (Article 1‚ pg.1) Muscular dystrophy effects homeostasis because abnormal genes (mutations) interrupts the production of proteins that the body needs to form healthy muscle. (Article 1‚ pg.1) The nine major forms of muscular dystrophy are Myotonic‚ Duchenne‚ Becker‚ Limb-girdle‚ Facioscapulohumeral‚ Congenital‚ Oculopharyngeal‚ Distal‚ and Emery-dreifuss. (Article 2‚ pg.1-2) The

How will Gene Doping effect the sports industry? Gene Doping is a different type of gene therapy that has caused a lot of controversy in the past 6-7 years due to the capability of what this method of doping could do. Gene doping therapy was started at Harvard in 1999 and was specifically used to get a substantial rise in the performance of athletes. This is done by genetically modifying cells to enhancing athletic performance. Gene therapy is done by using genes to help treat or stop diseases.

Introduction Jan Swammerdam‚ who demonstrated that an isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object‚ conducted the first muscle experiments between 1661 and 1665. Later‚ between 1737-1798 Luigi Galvani determined that frog muscle responded to electrical currents. The kymograph‚ which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The muscle

Cross Fontana Brandt Science Fair 22 April 2013 Grasping with Straws: Make a Robot Hand Using Drinking Straws Robotics is the science and technology of robots‚ their design‚ manufacture‚ and application. Robotics requires a knowledge of electronics‚ mechanics and software‚ and is usually accompanied by a large working knowledge of many subjects. The structure of a robot is mostly mechanical and can be called a kinematic chain. This is functionality being similar to the skeleton

The Exercise Benefits of Weight Loss Within the last few years some science has emerged that suggests exercise won’t help a person lose weight. In a 2009 Time Magazine article titled‚ “Why exercise won’t make you thin‚” author John Cloud makes an argument that exercise is a waste of time for dieters. Not only do I disagree with this hypothesis‚ I believe I’m living proof that exercise can help a person lose weight. I will show that there is scientific evidence that proves exercise promotes weight

Background Information Muscles in the human body can be classified into three different types- cardiac‚ smooth and skeletal muscles. The skeletal muscles are the muscles that can be controlled voluntarily‚ in things such walking and picking things up. The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two

The Effects of Creatine Creatine has been used in sports throughout time. Athletes have always had a fascination with being excellent at what they do. With the banning of steroids from competitive sports and the implementation of random drug testing in most sports‚ most athletes are still somehow hoping to gain an edge on their competition. This edge that they are using is creatine. In order to understand how creatine works‚ we must discover what creatine is. Creatine is an energy producing
