Model organism

include depressed mood, mood swing, loss of pleasure activities (anhedonia), inability to concentrate, lack of energy, disturbed sleep or appetite, feelings of worthlessness or guilt, and suicidal ideation and tendencies etc.(DSM-IV)(1994). Animal models of depression have a function of to replicate some known aspects of depression in preferred animal species (e.g. rodents).…

Introduction Caenorhabditis elegans is a common organism that is used in many experiments due to its easy upkeep, low cost, short life cycle, fast reproduction, large reproduction size, and genetic manipulability with transparent body structure (Maxwell C. K. Leung, Phillip L. Williams, et al.). The use of C. elegans has allowed many discoveries to be made throughout history. One experimental technique that enhances their use is a green fluorescence protein (GFP), this allows different regions…

understanding of plant nutrient requirements is important for the real world application of sustainable optimization of agricultural production for the human population (Reece et al. 2011). Arabidopsis thaliana has been extensively used as a research model in…

safe but using it with humans the medicine started causing heart problems. The advance if technology could provided a decline in animal experimentation. The improved technology such as cell-culture systems and microanalytic techniques; more detailed model systems; more improved understanding signaling and metabolic pathways; and a host of other methods that allow scientist to answer important questions about health and disease tissue without performing harmful…

Throughout history, animal experimentation has proved to be crucial to the development of our society. Since as early as the 17th century, we see how animal testings have led to important discoveries such as the understanding of the blood circulation and the function of the lungs in Medieval Europe . And now, scientists are relying on chimpanzees in hopes to help create the Hepatitis C vaccine . Overall, I believe that the state’s policy on animal experiments, as it is covered in the Criminal…

each run % AP was calculated manually by use of Archimedes principle. The observed response values (% AP) then put into CCD model and generate a response surface image (Figure 2). After that, the numerical optimization was done by maintaining all parameter values “in range” and response goal was set to “maximize” mode. The optimum parameter which was predicted by the RSM model was then validated experimentally in triplicates. 2.5. Scanning Electron Microscopy analysis of scaffold: The scaffold…

animals for human research. Animals are fundamental to biological and medical research. By researching and experimenting on them, we can learn more about different tissues and organs and how to maintain their health. Animal models help develop new treatments for diseases. Animal models contribute greatly to the development of new medicines, practicing surgical techniques, and developing new ways to prevent diseases. Animals naturally produce substances that can benefit medical research and…

for Medical Research in 1996. Computer modeling does indeed play an important role in research, but its ability to replace the use of animal is often limited. Before a scientist can program a computer to emulate the physiology of a human brain, a model is needed in order to study the physiology. Of course, this knowledge comes through the research of animals. So we still to study the animals before we can eventually rely on computer modeling. Computer are also hindered by its processing power. A…

Animal testing has been around for centuries, it started out to be for curiosity reasons; people wanted to learn more about the internal construction of the body, and animals were convenient--more so than humans. The word animal testing and animal research are interchangeable, but both relate to the same meaning: the use of animals in scientific experiments. The range of animals that are being tested on vary from lab to lab, but rabbits, guinea pigs, dogs, and rodents are some of the most…

diurnal animals. 2.) Differences in the sequences of PER genes can account for variance in the free running period (FRP) between varying organisms. 3.) Human PER gene homologs arose from prior duplication events throughout evolution. Motivation and Background: The biological clock is an endogenous mechanism that regulates the physiological activities of an organism. It was not until recently that much of the intricate molecular mechanisms or genes controlling the circadian rhythm were…
