Americans for Medical Advancement (AFMA) is a not-for-profit, science-based, patient advocacy organization dedicated to improving healthcare through biomedical research. It was founded by Ray and Jean Greek. [1]
The organization opposes the use of animals as causal analogical models, [2] or predictive models, for human response, and argues that using animals as a basis for the human response to drugs is not a safe method of development. [1] For example, efficacy testing, medical research, and ADMET (absorption, distribution, metabolism, elimination, and toxicity) are results from animal-based research that were assumed predictive for humans. The organization is relentlessly trying to have a peer reviewed debate with the animal researchers community on Trans Species Modelling Theory, in order for it to get accepted by the entire scientific community and get mainstream. [3] .It Is important to note that the most trivial consequence of Trans Species Modelling Theory is a defunding of animal tests and a massive increase in funds for preclinical human based animal free research. [4] AFMA is currently supporting the Parliamentary Early Day Motion 175 in UK [5] ,whose aim is a parliamentary peer reviewed scientific hearing on the validity of animal experiments when used to predict human response to drugs and disease [6]
Americans for Medical Advancement conducts its experiments through critical thinking and the use of evolutionary biology, complexity science, genetics, and personalized medicine. [1] None of these methods require testing on animals.
AFMA hopes to improve policy and decision-making regarding the use of the animal model in the testing of drugs and treatments for the safety of human use. The organization does not oppose the use of animals in other aspects of science, and stresses that it is not an animal rights group.
President, Ray Greek MD, says, “There are areas where animals are very useful in science and areas where they are not,” and that the organization “explores the differences between the two.” [7] What sets it apart is that it focuses “on the harm that is done to humans” and that animal protectionists are concerned about the harm done to animals.
Americans for Medical Advancement targets their work to improve healthcare. The way the organization hopes to do so is by developing safer, more efficient techniques to use in labs. Since AFMA believes that animals do not give an accurate reading of how drugs will make a human react, the first step would be eliminating animal testing in the development of drugs and treatments meant for humans. As a result, drug development should be quicker and more affordable. [1]
AFMA also wants to see medical research funding directed to more relevant areas of research that are often forgotten and not used. Some examples of scientific fields that AFMA believes are not applied enough when researching and creating drugs include complexity science, developmental biology, evolutionary biology, genetics and personalized medicine. [1]
Additional goals that the organization has are to have the requirements for animal testing reevaluated through the U.S. Food and Drug Administration and United States Environmental Protection Agency. AFMA also wants influential institutions such as the National Institutes of Health to stop encouraging animal models for research, so that other scientific organizations will steer away from animal testing.
The Trans-Species Modeling Theory (TSMT) was written by Ray Greek MD, the president of Americans for Medical Advancement. It states, “while trans-species exploration is possible when perturbations concern lower levels of organization or when studying morphology and function on the gross level, one evolved, complex system will not be of predictive value for another when the perturbation affects higher levels of organization.” [8]
In other words, when studying higher level organisms, the predictive value to drugs is not accurate because there are too many differences between their complexities. [2] These differences mean that there are different responses to treatments. Higher level organisms are so complex that there is a variation in responses, even within organisms of the same species, depending on each individual organism’s initial state.
Greek wrote the Trans-Species Modeling Theory using modern science and newer information. More commonly than not, the methods that scientist use today are based on findings from scientists from centuries ago. Many of those findings are outdated and no longer valid, but continue to be the basis of regulations for procedures used in scientific labs today. [9] Old findings suggested that there were more similarities than differences between similar mammals, so a monkey, for instance, would be tested for a certain heart condition in humans. Up to date science can now prove that although similar, a monkey's heart differs from a human heart, and therefore would not provide precise data in comparison to a human heart. [10]
Biology – The natural science that studies life. Areas of focus include structure, function, growth, origin, evolution, distribution, and taxonomy.
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinant DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40 with the lambda virus. As well as inserting genes, the process can be used to remove, or "knock out", genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome.
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.
A model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms. Model organisms are widely used to research human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution.
Pharmacology is a science of medical drug and medication, including a substance's origin, composition, pharmacokinetics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
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 history of biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine and the works of Aristotle, Theophrastus and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Avicenna. During the European Renaissance and early modern period, biological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms. Prominent in this movement were Vesalius and Harvey, who used experimentation and careful observation in physiology, and naturalists such as Linnaeus and Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organisms. Antonie van Leeuwenhoek revealed by means of microscopy the previously unknown world of microorganisms, laying the groundwork for cell theory. The growing importance of natural theology, partly a response to the rise of mechanical philosophy, encouraged the growth of natural history.
An animal model is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the risk of harming a human. Although biological activity in an animal model does not ensure an effect in humans, many drugs, treatments and cures for human diseases are developed in part with the guidance of animal models. Animal models representing specific taxonomic groups in the research and study of developmental processes are also referred to as model organisms. There are three main types of animal models: Homologous, Isomorphic and Predictive. Homologous animals have the same causes, symptoms and treatment options as would humans who have the same disease. Isomorphic animals share the same symptoms and treatments, only. Predictive models are similar to a particular human disease in only a couple of aspects. However, these are useful in isolating and making predictions about mechanisms of a set of disease features.
A complex adaptive system is a system that is complex in that it is a dynamic network of interactions, but the behavior of the ensemble may not be predictable according to the behavior of the components. It is adaptive in that the individual and collective behavior mutate and self-organize corresponding to the change-initiating micro-event or collection of events. It is a "complex macroscopic collection" of relatively "similar and partially connected micro-structures" formed in order to adapt to the changing environment and increase their survivability as a macro-structure. The Complex Adaptive Systems approach builds on replicator dynamics.
The philosophy of biology is a subfield of philosophy of science, which deals with epistemological, metaphysical, and ethical issues in the biological and biomedical sciences. Although philosophers of science and philosophers generally have long been interested in biology, philosophy of biology only emerged as an independent field of philosophy in the 1960s and 1970s, associated with the research of David Hull. Philosophers of science then began paying increasing attention to biology, from the rise of Neodarwinism in the 1930s and 1940s to the discovery of the structure of DNA in 1953 to more recent advances in genetic engineering. Other key ideas include the reduction of all life processes to biochemical reactions, and the incorporation of psychology into a broader neuroscience.
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch of biology and have a specific research focus.
Niall Shanks was an English philosopher and critic of intelligent design.
In the study of the biological sciences, biocommunication is any specific type of communication within (intraspecific) or between (interspecific) species of plants, animals, fungi, protozoa and microorganisms. Communication means sign-mediated interactions following three levels of rules. Signs in most cases are chemical molecules (semiochemicals), but also tactile, or as in animals also visual and auditive. Biocommunication of animals may include vocalizations, or pheromone production, chemical signals between plants and animals, and chemically mediated communication between plants and within plants.
The following outline is provided as a topical overview of science; the discipline of science is defined as both the systematic effort of acquiring knowledge through observation, experimentation and reasoning, and the body of knowledge thus acquired, the word "science" derives from the Latin word scientia meaning knowledge. A practitioner of science is called a "scientist". Modern science respects objective logical reasoning, and follows a set of core procedures or rules to determine the nature and underlying natural laws of all things, with a scope encompassing the entire universe. These procedures, or rules, are known as the scientific method.
The branches of science, also referred to as sciences, scientific fields or scientific disciplines, are commonly divided into three major groups:
Toxicology testing, also known as safety assessment, or toxicity testing, is the process of determining the degree to which a substance of interest negatively impacts the normal biological functions of an organism, given a certain exposure duration, route of exposure, and substance concentration.
Michael Terrence McGuire was an American psychiatrist who made contributions to the theory of psychoanalysis, biological psychiatry, evolutionary biology, sociobiology and the theory and practice of psychiatry.
