Using Gene Therapy as a treatment for Cystic Fibrosis Introduction: Gene therapy is a treatment which deals with a problem at its source, unlike other forms of treatment which merely eliminate the symptoms. Cystic Fibrosis (being a single gene disorder) should, theoretically, be one of the simpler diseases to cure using this method. In this paper Gene Therapy, in relation to the treatment of Cystic Fibrosis, will be discussed, along with its effectiveness and limitations. The process of Gene…

adjusting how much of each regulatory hormone to send to the renal system. It The antidiuretic hormone released from the posterior pituitary likely required time to reach the renal system to trigger the reabsorption of water through the aquaporin channels. In addition, there is a half-life for all hormones that regulate the renal system and as such will not immediately cease their functions. This includes Aldosterone which facilitates the reabsorption of sodium in the nephrons, since the…

Chapter-III OPERATING PRINIPLE AND LOSSES IN PEM FUEL CELL The polymer membrane is the heart of the PEM fuel cell which has some unique features. It allows protons but it is impermeable to gases, and hence it is known as a Proton Exchange Membrane. The membrane, which is squeezed between two electrodes (electrically conductive carbon cloths or carbon fiber papers) acts as electrolyte. A layer of catalyst particles (platinum) is placed at the interface between the porous electrode and polymer…

diffusion channels that are the main cause of the organic coating failure [109]. FIGURE 80 Evolution of the impedance modulus at the initial immersion stages for the uncured and cured P-ddm resin and its cured nanocomposites various nano-Cr2O3 contents. By analyzing data from Figure 81, it seems that a prolonged contact of the prepared coatings severe form decrease a slight in the high frequency modulus is noticed for all the nanocomposites after 6 days of immersions. Cr3+ ions and OH−…

Olfaction (smell) and Gustation (taste) work simultaneously with the aid of chemoreceptors, which generate nerve impulses. Chemoreceptors are able to combine the molecules that they recognize with a protein in order to create a channel on the surface of the receptors, which generates impulses. While they are both powerful senses, smell tends to be more responsive. The brain interprets the information given from taste and smell to help humans identify what it is they are eating. Scientists have…

Nucleus In each cell, there is one nucleus. It is in the center of the cell, and takes up about ten percent of the cell’s volume. It is a large, oval-shaped structure bound by a double membrane called the nuclear envelope. Inside the nucleus, are organelles called nucleoli, which assemble RNA and synthesize ribosomal subunits. Throughout the inside of the nucleus, is a substance called the nucleoplasm, which suspends the nucleus’ structures. The nucleus controls the activities of the cell to…

Ewha Park 03/19/2018 Water as Universal Human Need Water is a vital element for the survival of humans. Water is the main component in the human body (Children’s Prize para.2). However, most people are confronted daily by the situations of an inadequate supply of water that is safe leading to serious health problems. Water performs essential functions in our bodies including regulation of body temperature and maintenance of various bodily functions. Moreover, cells organs and tissues use water…

Whether one believes in a supernatural world or not at all, it is usually safe to say that every person has had an experience that sent chills down his or her spine. That eerie, hair-raising feeling may come from a chilling movie or simply walking around your own, silent house in the dark. No matter what the experience, most people are overcome by this emotion and feel the need to get out of his or her situation as soon as possible. The occurrence of this sensation is seen in the protagonist,…

Introduction Silver, like gold, is found in a native state; frequently too it occurs as an alloy containing gold, which is recognized, when the silver is dissolved in nitric acid, as the black sediment or oxide of gold. Arsenic and antimony are found also alloyed with it. Several of the ores of lead and copper contain silver. As silver is a precious metal often used for coins, its mining has historically often been lucrative. As with other precious metals such as gold, newly discovered deposits…
