Tumor Bank
A tumor bank is sometimes also referred to as a Tissue Bank, since normal tissues for research are also often collected. However, this function is distinct from a Tissue Bank which collects and harvests human cadaver tissue for medical research and education, and banks which store Biomedical tissue for organ transplantation. Cancer Samples Most tumor banks collect their tumor samples from discarded tissues not needed for pathologic diagnosis, after patients undergo surgery to remove the tumor. The method of sample preservation is critical, and must be compatible with the downstream analysis techniques. Tissue is often snap frozen in liquid nitrogen but may also be preserved in special fixative such as RNAlater (which preserves RNA and proteins), or formalin which preserves tissue architecture. Proteins and RNA can readily be extracted and characterized from tissue preserved with either method. Many Cancer Centers in the U.S. have a Tumor Bank to supply biomedical scientists with ...

Tissue Bank
A tissue bank is an establishment that collects and recovers human cadaver tissue for the purposes of medical research, education and allograft transplantation. A tissue bank may also refer to a location where biomedical tissue is stored under cryogenic conditions and is generally used in a more clinical sense. The United States Navy Tissue Bank is generally accepted as the first full tissue banking service of its kind in the world although it is not the largest or only tissue bank today. Donating a body Most medical schools need donated bodies for teaching students about the anatomy and physiology of the body, as well as how to perform medical procedures. There are no upper age limits for donating your body to science. Each school has different policies and procedures for donated bodies. Act 368 of the Public Acts of Michigan 1978, Article 10, Part 101, authorizes an individual to will their body to a medical institution. Medical institutions will only accept a full body, meaning ...

Biomedical Tissue
Biomedical tissue is biological tissue used for organ transplantation and medical research, particularly cancer research. When it is used for research it is a biological specimen. Such tissues and organs may be referred to as implant tissue, allograft, xenograft, skin graft tissue, human transplant tissue, or implant bone. Tissue is stored in tissue establishments or tissue banks under cryogenic conditions. Fluids such as blood, blood products and urine are stored in fluid banks under similar conditions. Regulation The collection, storage, analysis and transplantation of human tissue involves significant ethical and safety issues, and is heavily regulated. Each country sets its own framework for ensuring the safety of human tissue products. The regulation of human transplantation in the United Kingdom is set out in the Human Tissue Act 2004 and managed by the Human Tissue Authority. Tissue banks in the US are monitored by the Food and Drug Administration (FDA). The Code of Federa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Formaldehyde
Formaldehyde ( , ) (systematic name methanal) is a naturally occurring organic compound with the formula and structure . The pure compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous solution (formalin), which is also used to store animal specimens. It is the simplest of the aldehydes (). The common name of this substance comes from its similarity and relation to formic acid. Formaldehyde is an important precursor to many other materials and chemical compounds. In 1996, the installed capacity for the production of formaldehyde was estimated at 8.7 million tons per year. It is mainly used in the production of industrial resins, e.g., for particle board and coatings. Forms Formaldehyde is more complicated than many simple carbon compounds in that it adopts several diverse forms. These compounds can often be used interchangeably and can be interconverted. *Molecular formald ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NCI-designated Cancer Center
NCI-designated Cancer Centers are a group of 71 cancer research institutions in the United States supported by the National Cancer Institute. Program Three designations are recognized: Comprehensive Cancer Centers, Clinical Cancer Centers, and Basic Laboratory Cancer Centers. As of 2022, there are 52 Comprehensive Cancer Centers, 12 Clinical Cancer Centers, and 7 Basic Laboratory Cancer Centers. Almost all are associated with a university. Receiving the NCI-designation places cancer centers among the top 4 percent of the approximately 1,500 cancer centers in the United States. The standards for ''Comprehensive Cancer Centers'' are the most restrictive of the types. These facilities must demonstrate expertise in each of three areas: laboratory, clinical, and behavioral and population-based research. Comprehensive Cancer Centers are expected to initiate and conduct early phase, innovative clinical trials and to participate in the NCI's cooperative groups by providing leadership and ...

Translational Research
Translational research (also called translation research, translational science, or, when the context is clear, simply translation) is research aimed at translating (converting) results in basic research into results that directly benefit humans. The term is used in science and technology, especially in biology and medical science. As such, translational research forms a subset of applied research. The term has been used most commonly in life-sciences and biotechnology but applies across the spectrum of science and humanities. In the context of biomedicine, translational research is also known as bench to bedside. In the field of education, it is defined as research which translates concepts to classroom practice. Critics of translational medical research (to the exclusion of more basic research) point to examples of important drugs that arose from fortuitous discoveries in the course of basic research such as penicillin and benzodiazepines. Other problems have stemmed from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institutional Review Board
An institutional review board (IRB), also known as an independent ethics committee (IEC), ethical review board (ERB), or research ethics board (REB), is a committee that applies research ethics by reviewing the methods proposed for research to ensure that they are ethical. Such boards are formally designated to approve (or reject), monitor, and review biomedical and behavioral research involving humans. They often conduct some form of risk-benefit analysis in an attempt to determine whether or not research should be conducted. The purpose of the IRB is to assure that appropriate steps are taken to protect the rights and welfare of humans participating as subjects in a research study. Along with developed countries, many developing countries have established national, regional or local Institutional Review Boards in order to safeguard ethical conduct of research concerning both national and international norms, regulations or codes. A key goal of IRBs is to protect human subjects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooperative Human Tissue Network (CHTN)
The Collaborative Human Tissue Network (the CHTN) was established in 1987 by the National Cancer Institute in response to an increase in the demand for high quality biospecimens for cancer research. The purpose of the CHTN is to stimulate, for the good of the public, cooperative efforts to collect and distribute human biospecimens and to thereby facilitate research utilizing those specimens. These activities are expected to encourage basic and developmental studies in many areas of cancer research, including molecular biology, immunology and genetics. The CHTN is not intended to be a human tissue bank, but instead procures tissue at the request of an investigator. Limited banking was to be done as needed to meet specific requests and longer-term banking of targeted specimens to assure availability of rare and hard to obtain materials. It is funded under a UM1 NIH grant. The CHTN has six divisions, five adult divisions and one pediatric division. These divisions are located at the f ...
