alternative‚ the process of conducting this experimentation is too complex to be used globally; but there are other means of animal testing alternative. One of the disadvantages of using in vitro is that it does not decrease in the number of animals killed. Although in vitro uses only a small amount of an animal’s body part‚ it does not necessarily mean that theses animals are not killed. Important organs may be needed for testing‚ and to retrieve it‚ scientists

“Mom! Why was I not a designer baby?” “Well‚ sweetie‚ your father and I did not have the money to design our own child like all of our friends were doing at the time.” “I’m not as smart as all of the other kids in my class. I cannot run as fast as they can‚ and I cannot play an instrument like all of them can. I’m stupid! And it is because you did not design me to be any of those things‚ so now I am not good at anything!” Sadly‚ this is probably what the world’s new generation of children would

Therapeutic cloning is when a cloned embryo is formed by putting a nucleus from the patient’s cell into an egg without a nucleus. The cloned embryo then divides multiple times and forms into a sphere shape called a blastocyst (day 1-5). These embryonic stem cells are now visible and can be developed into any of the bodies 200+ tissue cells (day 5-7). After this stage the embryonic stem cells are removed and grown in a separate Petri dish. As they continue to divide‚ they create a line of stem cells

Exploring the Moral Fortress The controversy of stem cell research raises concerns of immorality as well has benefit of humanity. The immorality possesses a strong basis in religion and principals of life while the benefits of humanity overlook or prove morality on the basis of cost-benefit analysis. Religion and personal beliefs of life create the immorality argument. On the other hand‚ religion also creates an argument proving forms of cloning were biblically permissible along with research

EXSITU AND INSITU CONSERVATION OF MEDICINAL PLANTS INTRODUCTION India ranks sixth under world’s twelve mega bio-diversity zones. Out of these‚ two ofthem exist in our country. India possesses tremendous ecological bio-diversity. Itcontains 5 % of the world’s bio-diversity on 2 % of the earth’s surface. Thebiodiversity in our country is unique in nature and its in-situ and ex-situ conservationis very well needed. In recent years‚ the global demand of herbs has led to a quantumjump

Simulation of drought stress under in vitro conditions during the regeneration process constitutes a conventional way to study the effects of drought on the morphogenic responses (Sakthivelu et al.‚ 2008). Polyethylene glycol (PEG) of high molecular weights have been long used to simulate drought

Plant material was subjected to the extraction preparation by soxhlet apparatus by using various solvents such as aqueous‚ ethanol‚ chloroform‚ petroleum ether and hexane. The various kinds of phytochemicals were detected and then in vitro antidiabetic activity of P. guajava were detected by using alpha amylase and alpha glucosidase enzyme in an in vitro model.The study reveals the presence of phytochemicals such as carbohydrate

Animal Testing Every year‚ over 100 million animals are painfully put to death because of animal testing. Experimentation on animals goes way back since the beginning of time. Typically it is conducted for advancement in scientific research‚ to test products and food before going out into the market‚ to find treatments or test medical drugs‚ and to protect people and the environment. Animal experimentation has been a controversial issue for quite some time‚ but has yet to be put to an end. Vivisection

Poetry (2000)‚ in which the poems were all translated three times each into the three languages. A number of Singaporean writers such as Tan Swie Hian and Kuo Pao Kun have contributed work in more than one language. However‚ such cross-linguistic fertilisation is becoming increasingly rare and it is now increasingly thought that Singapore has four sub-literatures instead of one. Literature being an integral part of the culture of Singapore also portrays the specific aspects of the Singaporean society
