Stem Cell Research Stem cells have the ability to mold themselves into many different types of cells with specific attributes. Stem cells are basically cells that have not been placed into a specific categorized function. Stem cells have so far proved to provide treatment to various illnesses‚ such as cancer‚ multiple sclerosis‚ arthritis‚ Lou Gehrig’s disease‚ etc. So why is it not in blatant medical use today? Well‚ mainly because stem cells are noted as an act against God. The US government

that a new method to conduct chemical tests called in-vitro testing‚ allows researchers to conduct tests without the need to use animals. By introducing chemicals to animal cells in a petri dish or test tube‚ researchers are able to assess the danger of chemicals‚ without risking the lives of innocent animals. Other than that‚ NEAVS (2016) argues that in-vitro testing is also more accurate than animal testing. By using human cells in in-vitro testing‚ researchers are able to more accurately identify

2 Production of Protein from Cloned Genes Now that we have covered the basic techniques involved in gene cloning and DNA analysis and examined how these techniques are used in research‚ we can move on to consider how recombinant DNA technology is being applied in biotechnology. This is not a new subject‚ although biotechnology has received far more attention during recent years than it ever has in the past. Biotechnology can be defined as the use of biological processes in industry and technology

The Ethical Dilemma: Stem Cell Research “Ethics is knowing the difference between what you have a right to do and what is right to do.”- Potter Stewart One of the most controversial topics in today’s world is stem cell research. What are stem cells? Why is the debate about stem cells about ethics? Should stem cell research be allowed? What are the benefits of stem cell research? Stem cells are cells that have the potential to differentiate into a specialized cell such as liver cell. Scientists

Speak For Those Who Can’t Do the companies L’Oreal‚ Lancome‚ Garnier‚ Maybelline‚ Sephora‚ and Neutrogena sound familiar? All of these companies take part in animal testing. Every year 19.5 million animals die in testing every year‚ and these companies are involved. Products produced by these companies are some that one may use every day. Hopefully whoever uses their products feels guilty for putting those animals in all that pain and torture just to look pretty. Certainly‚ this is not a liable

main alternative involves the use of in-vitro technologies. These involve the production of cells or tissues that can be studied in a laboratory setting. Monamy explains that scientists can observe the effects of chemicals on ‘cultures’ rather than rats. If the chemical was supposed to cause heart problems‚ “…researchers can simply record changes in the beating of cultured heart cells in-vitro” (Monamy‚ 2000‚ 76). There are at least three reasons why the in-vitro method is better than using animals.

Down’s Syndrome Down’s syndrome is a genetic condition involving an extra chromosome‚ this change occurs around the time of conception. A person with Down’s syndrome has forty-seven chromosomes instead of the usual forty-six. A relatively common genetic disorder‚ Down’s strikes 1 out of 600 babies. In 95 percent of all cases‚ the disorder originates with the egg‚ not the sperm‚ and the only known risk factor is advanced maternal age-at age 35‚ a woman has 1 chance in 117 of having a baby with

With all the new technology that has been invented in recent years‚ it makes more sense to utilise the devices that have been created.

healthcare problem. Although myriad factors have been implicated in impaired wound healing‚ recent research has focused on the role of matrix-based bacterial communities called biofilms that are often associated with chronic wounds. Various in vitro and in vivo models have been developed to study the role of biofilms in non-healing wounds. Basic science and clinical studies suggest that effective eradication of pathogenic biofilms requires multimodality strategies including serial debridement

Indeed‚ there are many examples in the literature of highprofile failings of animal models to predict human toxicity[1-4]. • As such‚ there is a requirement in research for alternatives to both animal models and standard in vitro cell culture. • The Quasi-Vivo® culture system enables cell culture under laminar flow. This is designed to mimic the type of flow found in the body[5]‚[6] providing mechanical stimulation equivalent to blood and lymph movement‚ and ensuring constant
