Tissues Essay

September, 2013 Tissue Ownership “I think people are morally obligated to allow their bits and pieces to be used to advance knowledge to help others” (Korn). Different people have opposing opinions on the topic of whether or not patients or doctors own the body tissues after it’s been removed from the patient. Ownership is the act, state, or right of possessing something. Tissue ownership is different from ownership because once it leaves your body, you no longer own it. Contributing your tissues to the

Investigation of Tissues Tissues are defined as a group of associated, similarly structured cells that with their ground substance act together in the performance of a specialised function for the survival of the multicellular organism. The tissues are classified into four main groups which are epithelial, connective, muscle and nervous.

It is well noted that the massive increase of tissues samples most especially those with substantial clinical characterization led to the genotype and sequence data and commodification of biological tissues (Anderlik, 2003; Rose, 2001). Government agencies such the U.K. Medical Research Council gives funding for biobanks in concerned with tissues and genomes (e.g., brain banks). On the other hand, the cost of maintaining biobanks and its storage brings a huge issue in the monetary funding just like

Fetal Tissue Fetal tissue research is a particularly sensitive topic of discussion. It is a catalyst for fierce debates between vehement individuals on opposing sides. With such an exceedingly hot topic, the pros and cons are bound to be strong. The use of fetal tissue has allowed scientists to make many advancements, but the issues that arise from its utilization have long been discussed. In the world of science, the goal is to cure or eliminate all harmful diseases. This has led scientists to discover

Tissue Engineering Tissue engineering, labeled by Time.com as the number one hottest job for the 21st century, holds great potential for medicine and the treatment of chronic diseases and disorders. With tissue engineering, familiar problems like the rejection of foreign tissue by the body, the severe shortage of organ donors, and the inefficiency of artificial devices may be solved. However, this cutting edge biotechnology has already spurred intense controversy over the ethics and morality

Tissue biopsy Tissue biopsy is procedure done to take away cells or tissue from inside the body to look at with a microscope. A lung biopsy is a process where samples of the lung tissue are taken with a special needle, to find out if lung complications like lung cancer and other lung diseases are present. Tissue biopsy is done for the following reasons:  To examine an abnormality found on chest X- rays or CT scans  To diagnose infections of the lungs and other lung diseases  To study carefully

Furthermore, tissue microarrays are another high-throughput technique that permits multiple assays to be performed for multiple patients on a single slide as up to 1000 tissue samples can be arrayed into a single paraffin block and IHC or FISH performed simultaneously on multiple samples and under identical processing conditions. (Kumar et al .2012) The high accuracy tissue microarray instrument obtains tissue cores from predefined areas of tissue sample paraffin blocks and places them precisely

Granulomatous tissue is a typically small area of inflammatory cells that have fused together, to create large multinucleated cells to fight against infectious bacteria. Granulomas are most prominently located in the lung, though they can also be found throughout various parts of the body, often due to prolonged infection. The inflammation in granulomas, is a cell-mediated hypersensitive reaction to persistent micro bacteria, often found in pulmonary infections, whether it be a fungal, bacterial

Brain tissue can be classified into three tissue types; grey matter (GM), white matter (WM) and cerebro-spinal fluid (CSF). Initially, all MR images are segmented into three images, each represents one tissue type. The segmented images are then registered iteratively with their average to estimate the deformations that best align the images together. These deformations are used to generate spatially normalized and smoothed gray matter images. The image values after seg- mentation represent the probability
