Tissue culture has been in practice since the early 1900’s. Since its start, there has been many breakthroughs in producing a viable plant from culture. Tissue culture is defined as the growth of plants from plant tissue in an artificial medium and a sterile environment. The uses for this technique include food processing, agriculture, pharmaceutics, and medicines. It has an influence on human welfare like food processing, human health, and environmental protection. There is an increasing demand
carry viruses and fungal pathogen (Jong, 2012). Therefore, tissue culture is the alternative to the conventional method for banana production. Tissue culture method benefits the production of bananas by producing plants that are free of diseases, faster growth rates, greater yield and safe for human consumption (Increasing banana yields by using tissue culture method, n.d.). According to Tissue Culture (n.d.), the main purpose of tissue culture is to produce healthy plantlets that are free of virus diseases

Niemann: Pick's Disease Niemann Pick disease consists of a group of genetic disorders in which the common feature is a varying degree of sphingomyelin storage in certain tissues of the body. According to the current classification based on the enzymatic defect underlying these disorders, two main groups are distinguished. The first group, which comprises type A, which is characterized by a severe deficiency in acid sphingomyelinase activity, includes infantile neuronopathic form; and type B
functional specialized cells. Also cancer cells growing in laboratory tissue culture do not stop growing when they touch each other on a glass or other solid surface but grow in masses several layers deep they are said to lack contact inhibition. Loss of contact inhibition accounts for two other characteristics of cancer cells invasiveness of surrounding tissues and metastasis spreading via the lymph system or blood to other tissues and organs. Cells are typically controlled by growth factors competence
contain some contradictions, his overall points appear regrettably compelling and difficult to refute. By medical definition, a malignant neoplasm is diagnosed on the basis of four main qualities: unrestrained growth, consumption of surrounding tissues, spreading to satellite regions and de-differentiation of cells. According to Dr. Hern, the human population reflects each of these characteristics in some way. He anchors his argument by systematically linking each of these four cancer indicators
Looks and Love Before I left home for college, my group of friends and I sat down for one last serious heart-to-heart. Sometime during our conversation, the question of college choice arose. Emotions escalated as we realized how far apart we would be in a short time. "Why did you choose to go to MIT?" they asked, "Why couldn't you just stay home at a state university?" Wanting to lighten the mood, I replied, laughing, "That's an easy one...the guys, of course!" And after the initial uproar of
Authors have explained the ramification and growth of post surgical scar tissue on the fascial system, despite that literature explains a scope of theories. This appraisal will focus on its major thesis questioned and emerged frequently by many authors ,this review will begin with emphasising on the justification of all findings subsequently. Hence investigating all current postulation in the literature on post surgical scar tissue development and effect on the fascial system, this study consequence
This conductive hearing loss is caused by the growth of a spongy bone-like tissue that prevents the ossicles (bones of the middle ear) from moving well. One of the first signs is a small growth of the tissue in the middle ear. This is often in front of the oval window, which separates the middle ear from the inner ear. This can begin in early childhood or adolescence. The tissue may grow rapidly and become hard. The bone tissue grows over the stapes ossicle attaching it to the oval window. At first
psychadelic- it is a neurotransmitter found naturally in the human body and takes part in normal brain metabolism. Twenty-five years ago, Japanese scientists discovered that the brain actively transports DMT across the blood-brain barrier into its tissues. "I know of no other psychedelic drug that the brain treats with such eagerness," said one of the scientists. What intrigued me were the questions, how and why does DMT alter our percep... ... middle of paper ... ... in the action of hallucinogens
aureus food poisoning, but in some instances individuals will require more time to fully recover. Even though S. aureus is mainly associated with food poisoning, the bacterium can penetrate the skin or other mucous membranes to invade a range of tissues which will cause a variety of infections. Superficial infection of the skin can cause boils, impetigo, styes (infection of the glands or hair follicles of the eyelids), folliculitis, and furnacles. All of these infections are charac... ... middle
Forensic Pathology as a Career The career that I researched was forensic pathology. The job of a pathologist is to determine a person’s cause of death by examining tissues and fluids from the body. A forensic pathologist does this as well, but they are trained to examine people who died unexpectedly or violently and to recognize other things that a regular pathologist might not, such as recognizing something as intentional rather than accidental. They have to determine who the person is, the time
life when life extension and anti-aging have become a reality. However, there is a lot of damage done to the body during this freezing, says Dr. Ralph Merkle, a professional in the field of cryonics. First there are fractures that form in the frozen tissues caused by thermal strain, if you were warmed up you’d fall into pieces as if cut by thousands of sharp knives. And Second, the Cryotransport is used as a last resort because legally the Cryotransport can’t even begin until the patient is legally dead
unnoticeable. The next stage of the measles happens after eight to twelve days. The infected person has symptoms of fever, weakness and loss of appetite. Coughing and running of the eyes and nose are also seen. Now the infection is spreading all over the tissues through out the body. They also trigger the body’s immune system, which causes the symptoms. When the measles virus infects the immune system and interacts with the antibodies and T cells, a measles rash begins on the face and very quickly spreads
inflammation of the bursa that is easily prevented, detected and treated. Bursitis is a common condition that can cause much pain and swelling around an affected bursa. A bursa is a sac between body tissues that move against each other. They are filled with a lubricating liquid to minimize the fiction between the tissues. The bursa are found mostly in joints between skin and bone or bone and tendons. When you irritate these lubricating sacs, the bursae fill with fluid and become irritated and inflamed. This
Cutaneous membrane also know as the skin. The cutaneous membrane actually has a surface area of over 20 feet and is actually an organ, comprised of all four tissue types, epithelial, connective, muscle, and nervous. Because of this and having several accessory organs, the Cutaneous membrane is considered to be an organ system. The cutaneous membrane is comprised of three different layers, the epidermis, the dermis, and the hypodermis, each with their own purpose and characteristics. The epidermis
Damaged tissue (inflammation) Inflammation is the body’s response to injury. Inflammation is a protective attempt by the body to attempt to remove harm and to initiate the healing process. Inflammation occurs with a few minutes of the incident up to a few hours after depending on the severity of the injury. There are 5 key characteristics of inflammation these are: • Pain • Redness • Swelling • Heat • Immobility (loss of use) Injury causes Tissue damage.
definition of xenotransplantation which they say is “any procedure that involves the transplantation, implantation, or infusion into a human recipient of either live cells, tissues, or organs from a non human animal source, or human body fluids, cells, tissues or organs that have had ex vivo contact with live non human animal cells, tissues or organs.” The main interest of the practice is to be able to take organs from animals for the purpose of using them in humans in need of organ transplants. It is still
widely collected. The genus of the cinquefoil’s Potentilla from Latin meant “powerful” was derived from its reputation as powerful cure-alls. In particular, the Potentilla erecta (Tormentil) was used as an antibiotic and an astringent (causing tissues to contract). Another bog plant, the Cladonia species was classified as an effective medicinal herb in the Middle Ages, but is only used today as fabric dyes. Some bog plants such as the Osmunda regalis (Royal Fern) were used during the colonial
blood in the urine, and nagging pain in the back, hips, or pelvis. Often, there are no early symptoms of prostate cancer. Once cancer of the prostate has been found, tests are done to find out if cancer cells have spread from the prostate to tissues around it, or to other parts of the body. This is called “staging.” It is very important to know the stage if the disease to plan for the treatment. The following stages are used for prostate cancer: Stage 1: Prostate cancer at this stage cannot
