Tissue tropism is a term most often used in virology to define the cells and tissues of a host biology host which support growth of a particular virus biology virus . Bacteria and other parasites may also be referred to as having a tissue tropism. Some viruses have a broad tissue tropism and can infect many types of cells and tissues. Other viruses may infect primarily a single tissue. For example Rabies virus affects primarily neuron al tissue, and Hepatitis primarily affects liver tissue. Influencing factors Factors influencing viral tissue tropism include The presence of cellular receptor biology receptors permitting viral entry. Availability of transcription factor s involved in viral replication. The molecular nature of the viral tropogen . The cellular receptor biology receptors are the proteins found on a cell or viral surface. These receptor biology receptors are like keys allowing the viral cell to fuse with a cell, or attach itself to a cell. The way that these proteins are acquired is through similar process to that of an infection cycle.

Unreferenced date December 2010 Tissue hydration is the process of absorbing and retaining water in Tissue biology biological tissues . Plants Land plants maintain adequate tissue hydration by means of an outer waterproof layer. In soft or green tissues, this is usually a waxy plant cuticle cuticle over the outer epidermis botany epidermis . In older, wood y tissues, waterproofing chemicals are present in the secondary cell wall that limit or inhibit the flow of water. Vascular plant s also possess an internal vascular system that distributes fluid throughout the plant. Some xerophyte s, such as Cactus cacti and other desert plants, have mucilage in their tissues. This is a sticky substance that holds water within the plant, reducing the rate of dehydration. Some seed s and spore s remain dormant until adequate moisture is present, at which time the seed or spore begins to germinate. Animals Animals maintain adequate tissue hydration by means of 1 an outer skin , Exoskeleton shell , or cuticle 2 a fluid filled coelom cavity and 3 a circulatory system . In humans, a significant drop in tissue hydration can lead to the medical condition of dehydration . This may result from loss of water itself, loss of electrolytes, or a loss of blood plasma.

Tissue typing is a procedure in which the tissues of a prospective donor and recipient are tested for compatibility prior to Organ transplant transplantation .

In this technique a donor s blood cells are major histocompatibility complex MHC typed by mixing them with Blood serum serum containing the anti HLA antibodies . If the antibodies recognize their epitope on the MHC then classical complement pathway complement activation occurs and the cell will be osmotically lysis lysed . Lysis results in the cell taking up a dye trypan blue . This allows identification of cell s MHC indirectly based on the specificity of the known antibodies in the serum.

Nervous tissue is the main component of the nervous system the brain, spinal cord, and nerves which regulates and controls body functions. It is composed of neuron s, which transmit impulses, and the neuroglia cells, which assist propagation of the nerve impulse as well as provide nutrients to the neuron. Nervous tissue is made of nerve cells that come in many varieties, all of which are distinctly characteristic by the axon or long stem like part of the cell that sends action potential signals to the next cell. Functions of the nervous system are sensory input, integration, controls of muscles and glands, homeostasis, and mental activity. All living cells have the ability to react to stimuli. Nervous tissue is specialized to react to stimuli and to conduct impulses to various organs in the body which bring about a response to the stimulus. Nerve tissue as in the brain, spinal cord and peripheral nerves that branch throughout the body are all made up of specialized nerve cells called neurons . Neurons are easily stimulated and transmit impulses very rapidly. A nerve is made up of many nerve cell fibers neurons bound together by connective tissue.

Merge from Resomation discuss Talk Tissue digestion Merger proposal date March 2011 Refimprove date May 2007 Tissue digestion is a method of disposing bodies. The scientific term is alkaline hydrolysis . It is used at several university universities for the remains of animal cadavers as well as for human remains. In mortuary usage, the process is called water reduction resomation or aquamation . Methods The remains are dissolved in a mixture of heated water and lye or potassium hydroxide. The solid remains are reduced to 2 to three percent of the original body weight. After the process is completed, only remnants of the bones of a body remain, and these can be ground in one s hand. The remaining protein matter of the body has been dissolved by the lye into a sterile liquid. Two main methods have been introduced for human remains, the main difference is in the temperatures the units operate at resomation works at 180 degrees C, and aquamation at 93 degrees C. Invention Alkaline hydrolysis was patented in the US by Amos Herbert in 1888. The process was revisited by retired pathology professor Gordon Kaye and retired biochemistry professor Peter Weber in 1992. It was utilised as a method of disposing of animals remains used in disease research. ref The Mayo Clinic Cite book title Stiff The Curious Lives of Human Cadavers last Roach first Mary authorlink Mary Roach isbn 0 393 32482 6 publisher W.

Gamgee Tissue is a Dressing medical surgical dressing invented by Dr. Joseph Sampson Gamgee in Birmingham , England , in 1880. Gamgee Tissue has a thick layer of absorbent cotton wool between two layers of absorbent gauze. It represents the first use of cotton wool in a medical context, and was a major advancement in the prevention of infection of surgical wounds. It is still the basis for many modern surgical dressings. The name is a trademark , and has been since 1911. Tolkien In Birmingham, Gamgee became the colloquial name for cotton wool, which possibly led to the character name Sam Gamgee in J. R. R. Tolkien s The Lord of the Rings . The connection is not certain in Appendix F to The Lord of the Rings , Tolkien mentions, but at the same time denies, the reading of Gamgee as a pun relating to the name of Sam s wife, Rosie Cotton . He further elaborates the real Westron names of which Gamgee and Cotton are translations. However, in the same section Tolkien also addresses hobbit which was certainly created first and translated afterward, as described in Tolkien s own comment on the initial writing of The Hobbit and Brandywine an obvious English pun on the Elvish Baranduin , justified as translation of a similarly alcoholic pun in Westron . In this context we may suspect that the Professor is speaking tongue in cheek the Gamgee entry is phrased such that it can be read as a poker faced, academic way of pointing out that the joke is there, whether or not he intended it.
