chemical reacts with human cells and the human body. According to ProCon.org‚ in vitro testing is another option as an alternative to animal testing‚ this involves observing cells in a petri dish and recording the reactions the cells have to the chemicals being tested. In vitro testing is less expensive than animal testing. For example DNA analysis in an animal can cost about $32‚000 whereas the equivalent test for the in vitro alternative only costs $11‚000. Further‚ to test products that would touch

The issue of stem cells is currently the dominant subject in the debate of biotechnology and human genetics: Should embryonic or adult stem cells be used for potential medical therapies? Stem cells are an undifferentiated cluster of cells which‚ depending on their surrounding conditions‚ are capable of developing into other types of cells (Perry 20). The expression "stem cell" refers to a type of cell that not only produces various types of additional cells‚ but also has the ability to replicate

This study shows that tea increased antibacterial activity of norfloxacin. A previous in vitro study demonstrated that the constituents of tea are indifferent to the antimicrobial effect of ciprofloxacin while it enhances that of tetracycline (Ahmad and Aqil‚ 2007). Since tea extracts possess antimicrobial property‚ it may be that the synergy

Familial Hypercholesterolemia Familial Hypercholesterolemia is an inherited genetic disorders which causes the body to be unable to remove and regulate the amounts of low density lipoprotein (LDL). [1] Due to its hereditary source‚ Familial Hypercholesterolemia usually begins at an early age‚ causes heart attacks and contributes to the development of Atherosclerosis. The human body regulates concentrations of low density lipoprotein in the body using LDL receptor genes‚ [2] but missense mutations

Side of Prenatal Testing”‚ “Science has given parents a better option. Using their own sperm and eggs can be used to make embryos outside of their body” (28-29). Embryos made by Vitro fertilization can be easily tested for the genetic disease. After testing‚ only the healthy embryos are put in the mother’s uterus. Vitro fertilization reduces the risk of pregnancy loss and raises the chance for a healthy

Intoduction Stem cell research has brought about heated debate among academics and society as a whole. Especially among Christian circles. Embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in vitro or at an in vitro fertilization clinic which are then donated for research purposes with informed consent of the donors. They are not derived from eggs fertilized in a woman ’s body contrary to the belief of some. The pros and cons of stem cell research come

Many important Chinese medicinal herbs have been successfully propagated in vitro‚ either by organogenesis (Erdei et al. 1981‚ Shoyama et al. 1983‚ Hatano et al. 1986‚ Matsumoto et al. 1986‚ Hiraoka and Oyanagi

Everyday animals have to endue torture and agony people put them through because of animal testing. Whether it is for medical research or for cosmetic testing they are subjected to bleed‚ being burned‚ blinded‚ or become deceased. Sometimes these animals are put through this for the most arbitrary reasons such as makeup remover and eyeliner. The use of animal testing is cruel‚ ineffective‚ and a waste of money. Animal testing is undeniably cruel and inhumane. The daily life of an animal being kept

Unfortunately‚ that isn’t going to happen anytime soon. A 2004 law called the Assisted Human Reproduction Act (AHR Act) states that it’s a criminal offence “to alter the genome of a human cell‚ or in vitro embryo‚ that is capable of being transmitted to descendants”. And it’s so broadly written that Canadian scientists are prohibited from using the technology on even somatic cells. Today Canada is one of the few countries in the world where treating
