In vitro studies are performed with microorganisms, cells, or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from in vitro experiments may not fully or accurately predict the effects on a whole organism. In contrast to in vitro experiments, in vivo studies are those conducted in living organisms, including humans, known as clinical trials, and whole plants.
Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms and the practice of diagnosing and treating exposures to toxins and toxicants. The relationship between dose and its effects on the exposed organism is of high significance in toxicology. Factors that influence chemical toxicity include the dosage, duration of exposure, route of exposure, species, age, sex, and environment. Toxicologists are experts on poisons and poisoning. There is a movement for evidence-based toxicology as part of the larger movement towards evidence-based practices. Toxicology is currently contributing to the field of cancer research, since some toxins can be used as drugs for killing tumor cells. One prime example of this is ribosome-inactivating proteins, tested in the treatment of leukemia.
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals in experiments that seek to control the variables that affect the behavior or biological system under study. This approach can be contrasted with field studies in which animals are observed in their natural environments or habitats. Experimental research with animals is usually conducted in universities, medical schools, pharmaceutical companies, defense establishments, and commercial facilities that provide animal-testing services to the industry. The focus of animal testing varies on a continuum from pure research, focusing on developing fundamental knowledge of an organism, to applied research, which may focus on answering some questions of great practical importance, such as finding a cure for a disease. Examples of applied research include testing disease treatments, breeding, defense research, and toxicology, including cosmetics testing. In education, animal testing is sometimes a component of biology or psychology courses. The practice is regulated to varying degrees in different countries.
The National Institute of General Medical Sciences (NIGMS) supports basic research that increases understanding of biological processes and lays the foundation for advances in disease diagnosis, treatment, and prevention. NIGMS-funded scientists investigate how living systems work at a range of levels, from molecules and cells to tissues and organs, in research organisms, humans, and populations. Additionally, to ensure the vitality and continued productivity of the research enterprise, NIGMS provides leadership in training the next generation of scientists, in enhancing the diversity of the scientific workforce, and in developing research capacity throughout the country.
The following outline is provided as an overview of and topical guide to neuroscience:
The blastocyst is a structure formed in the early embryonic development of mammals. It possesses an inner cell mass (ICM) also known as the embryoblast which subsequently forms the embryo, and an outer layer of trophoblast cells called the trophectoderm. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoel. In the late blastocyst, the trophectoderm is known as the trophoblast. The trophoblast gives rise to the chorion and amnion, the two fetal membranes that surround the embryo. The placenta derives from the embryonic chorion and the underlying uterine tissue of the mother.
In the animal rights movement, cruelty-free is a label for products or activities that do not harm or kill animals anywhere in the world. Products tested on animals or made from animals are not considered cruelty-free, since these tests are often painful and cause the suffering and death of millions of animals every year.
The Johns Hopkins University Center for Alternatives to Animal Testing (CAAT) has worked with scientists, since 1981, to find new methods to replace the use of laboratory animals in experiments, reduce the number of animals tested, and refine necessary tests to eliminate pain and distress. CAAT is an academic, science-based center affiliated with the Johns Hopkins Bloomberg School of Public Health.
The Institute of Psychiatry, Psychology & Neuroscience (IoPPN) is a leading centre for mental health and neuroscience research, education and training in Europe. It is dedicated to understanding, preventing and treating mental illness, neurological conditions, and other conditions that affect the brain. The IoPPN is a faculty of King's College London, England, and was previously known as the Institute of Psychiatry (IoP).
The Oklahoma Medical Research Foundation (OMRF), located in the Oklahoma Health Center in Oklahoma City, Oklahoma, is an independent, nonprofit biomedical research institute. Established in 1946, OMRF is dedicated to understanding and developing more effective treatments for human disease. Andrew S. Weyrich, Ph.D. serves as president of OMRF, which employs more than 500 scientific and administrative staff members.
A biomedical scientist is a scientist trained in biology, particularly in the context of medical laboratory sciences or laboratory medicine. These scientists work to gain knowledge on the main principles of how the human body works and to find new ways to cure or treat disease by developing advanced diagnostic tools or new therapeutic strategies. The research of biomedical scientists is referred to as biomedical research.
Walter Robert Hadwen was an English general practitioner, pharmaceutical chemist and writer. He was president of the British Union for the Abolition of Vivisection (BUAV) and an anti-vaccination campaigner, known for his denial of the germ theory of disease.
The Kolling Institute is located in the grounds of the Royal North Shore Hospital in St Leonards, Sydney Australia. The institute, founded in 1920, is the oldest medical research institute in New South Wales.
Gillian Rose Langley is a British scientist and writer who specialises in alternatives to animal testing and animal rights. She was, from 1981 until 2009, the science director of the Dr Hadwen Trust for Humane Research, a medical research charity developing non-animal research techniques. She was an anti-vivisection member of the British government's Animal Procedures Committee for eight years, and has worked as a consultant on non-animal techniques for the European Commission, and for animal protection organizations in Europe and the United States. Between 2010 and 2016 she was a consultant for Humane Society International.
Alternatives to animal testing are the development and implementation of test methods that avoid the use of live animals. There is widespread agreement that a reduction in the number of animals used and the refinement of testing to reduce suffering should be important goals for the industries involved. Two major alternatives to in vivo animal testing are in vitro cell culture techniques and in silico computer simulation; however, some claim they are not true alternatives because simulations use data from prior animal experiments and cell cultures often require animal derived products, such as serum or cells. Others say that they cannot replace animals completely as they are unlikely to ever provide enough information about the complex interactions of living systems.
Europe PubMed Central is an open-access repository that contains millions of biomedical research works. It was known as UK PubMed Central until 1 November 2012.
The National Animal Welfare Trust (NAWT) is an animal welfare charity founded in 1971, which operates rescue and rehoming centres for companion animals. It has branches in Watford, Berkshire, Essex, Bedfordshire and Cornwall. They operate a number of premises, including Trindledown Farm, the UK's only retirement home for elderly pets. Formerly known as the Animal Welfare Trust (AWT), it originated from the British Union for the Abolition of Vivisection.
