The Effect Of Soft Tissue Constituent Materials - 1422 Words

The goal of this thesis is to identify the effect of soft tissue constituent materials in tissue classification for the application of breast cancer detection. Hyperelastic parameters may be essential in estimating large deformation in tissue for the purpose of surgical procedures such as breast brachytherapy. These properties of human soft tissue play a significant role in diagnosis, screening, and monitoring of cancer (O’Hagan Samani, 2009). On the other hand, elastography is based mainly on the concept of tissue reactions (linear and nonlinear) to an external source of load such as compression. Moreover, in most breast examination methods, compression is applied to help detect lesions. In CBE and BSE, the examiner applies a compressive load to the breast to investigate stiff regions and must sometimes exert a large deformation to feel lesions in depth. Mammography also uses compression to reduce breast thickness. Additionally, compressive behavior of human breast biopsies obtained through lumpectomy (the surgical procedure to remove a cancer or non-cancer breast lump with some surrounding tissues) is of interest to the cancer research agencies in order to distinguish the mechanical nature of anomalies of the taken biopsy. Despite of the importance of compressive loading and its contribution to hyperelastic characterization of tissue in 9 applications of cancer detection, few studies have focused on the behavior of tissue components in response to compression.

Usually, anomalies found within the breast are investigated by palpation techniques, in which responses of soft tissue to large deformation are utilized (Goodson, 1996). Recent research on the mechanical properties of soft tissue under compressive load has revealed that tissues exhibit a linear stress-strainRead MoreDecay Of Decay And Decay1506 Words   |  7 Pagesaction and they contain radionuclide. They are prepared by labeling the selected carrier constituent with a suitable radioactive isotope. The carrier of the radiopharmaceutical is a biologically active molecule used to concentrate the drug in a specific organ or group of organs to give diagnostic data about those tissues such as pyrophosphate and methylene diphosphonate (MDP) compounds in skeleton bone tissues.

In the past 70 years ceramics have started to be used in the medical field1. Ceramics can be categorized by its bio-safety and bioactivity. Bio-safe materials are non-toxic and non-inflammatory as to avoid rejection from the body. Where the bioactivity is how it reacts to biological material and processes. Typically ceramics have been used in surgical replacements such as bones and teeth. These ceramics must be designed and optimized in order to perform in the body’sRead MoreAn Overview On Topical Conveyance Framework1260 Words   |  6 Pagesthixotropic, greaseless, effectively spreadable, effortlessly removable, emollient, non-recoloring, water-dissolvable, longer timeframe of realistic usability, bio-accommodating, straightforward and satisfying appearance.

Eating fish contaminated with mercury has caused poisoning in humans; birds and land animals exposed in the same manner could also be subject to the same effects. Mercury and its compounds are highly persistent in water and the environment and will bio accumulate or concentrate in the tissues of fish. These concentrations will be considerably higher than the water from which the fish is taken. Mercury chloride will act as a particle, following wind patterns, and being depositedRead MoreA Description Of The Biology Of Bone5430 Words   |  22 Pagesthem and the present thesis project. 2.2 Bone Structure and Composition Bones are complex structures composed of bone tissue, bone marrow, nerves and vasculature. The osseous tissue or bone tissue refers to the mineral content, matrix components and bone cells within it. This tissue is constantly remodeling itself as the organism grows and develops. Bone tissue must meet several characteristics; it has to be stiff in order to provide structural support to the body, light to facilitateRead MoreFood and Industrial Microbiology6654 Words   |  27 Pagesunacceptable for human consumption and may result from a variety of causes, which includes i) insect damage; ii) physical injury due to freezing, drying, burning, pressure, drying, radiation etc; iii) activity of indigenous enzymes in plant and animal tissues; iv) chemical changes not induced by microbial or naturally occurring enzymes.

The highest change in lead concentration was observed at setups containing 635.00 ppm lead while the lowest change in lead concentration was observed at setups containing 335.00 ppm. As expected, the plant tissues retained the lead nitrate. Concentrations of lead in plant tissues should show the same trend as that of soil. Based on this result, it can be conclude that Dwarf santan may used as an effective and alternative phytoremediation agent on lead (II) contaminated soil.
