Germany. These men started using mammography for the diagnosis and evaluation of breast cancer. With this popularity of mammography came vast improvements with technology. Before 1969‚ many machines were not designed for imaging exclusively breast tissue. For example‚ imaging units from the past were comprised of tungsten targets‚ which were primarily used for imaging anatomy that required relatively higher doses of radiation. These units also worked off of a large focal spot which decreases the detail

Nutritional requirements The composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro

Fetal Tissue Transplantation”‚ by Scott B. Rae. This article covers strong points such as science‚ laws‚ ethics‚ restrictions‚ and alternatives. With all the information presented in this article I find it extremely unethical to use fetuses from voluntary abortions to assist in medical care. In 1988 there was an experiment done on a 52-year-old man with Parkinson’s disease. They implanted fetal brain cells in his brain. He reported an improvement in his ability to walk and speak.

Outline and evaluate the role of neural mechanisms in controlling eating behaviour (24 marks) Today there is enormous interest in the psychological factors that can affects a person’s eating habits‚ but some of the clearest research findings have come from research into the brain (neural) mechanisms controlling eating behaviour. One important mechanism to consider is the role of homeostasis in all mammals. Homeostasis is how the body maintains a constant internal environment. Our diet is essential

Objective: To study osmosis in living plant tissue. Biological principles: Water potential is the tendency for water molecules to enter or leave a system by osmosis through a differentially permeable membrane‚ while osmosis is the process in which water molecules move passively from a region of higher water potential to a region of lower water potential through a differentially permeable membrane. Therefore‚ potato cells‚ with their differentially permeable membrane‚ are selected as the medium

always propagated in a micro way‚ tissue culture is the most popular method for micro-propagation in Alstroemeria. Tissue culture involves the use of small pieces of plant tissue (explants) which are cultured in a nutrient medium under sterile conditions. Using the appropriate growing conditions for each explant type‚ plants can be induced to rapidly produce new shoots‚ and‚ with the addition of suitable hormones new roots. Alstroemeria explants used in tissue culture consist of a rhizome
