Discussion questions: 1. At what point should limits be placed on what can be done to the human body or should there be limits at all? There are several scientists around the world who are quite open about their willingness to clone a human. Should technology be developed that allows this? Why or why not? With our world’s technology growing at a substantial rate, there should be limitations placed on what can be done to the human body. I believe the technology to clone human beings is far too

nanoT - VaryCell TM Micro stage for time lapse imaging and temperature mediated cellular studies. Cells derived from mammals have an optimum in vitro growth rate between 36°C to 37°C as their in vivo physiological temperature ranges between 36.5–37.5 °C (97.7–99.5 °F) in a normal individual. Homeostasis process maintains the constancy of the organism’s internal environment in response to changes in external conditions. Thermoregulation is part of the aforementioned process as controlled by the

Background Pseudomonas aeruginosa is an important cause of hospital acquired infection. It is frequently recovered species from clinical specimens and multidrug resistant P. aeruginosa are increasingly being reported worldwide. The important factor responsible for aminoglycoside resistance is Aminoglycoside modifying enzymes (AMEs), carried by mobile genetic elements. In spite of high resistance, aminoglycosides are still an important treatment option in infection with P. aeruginosa. Aim: The study

CHAPTER I INTRODUCTION RESEARCH BACKGROUND This research is about the extraction of keratin protein from chicken feathers using strong fluid extraction process. This extraction procedure utilized a dissolvable as lessening specialists to separate salt linkages, disulphide bond and hydrogen bond of the keratin fiber to break down into protein. Thus, it will likewise diminish the steadiness of keratin strands in the strong structure found in feathers. Proteins are polymer formed by one or

REVIEW OF LITERATURE The first tracheal intubation was reported in 1543 by Vesalius in an animal . In the early 1870's, Trendelenburg from Germany performed the first endotracheal anesthesia in man. Macewen in 1878 reported the first elective endotracheal intubation for anesthesia.(21) CIRCULATORY RESPONSE DURING LARYNGOSCOPY AND TRACHEAL INTUBATION : The effects of endotracheal intuabation and laryngoscopy producing pressor response causing tachycardia, rise in BP and cardiac arrhythmia

Indirect ELISA The term "indirect ELISA" refers to an ELISA in which the antigen is bound by the primary antibody, which then is detected by an enzyme labeled secondary antibody. The Secondary antibodies were raised against the primary antibody in other species of animal by immunization. The indirect ELISA has advantages over the direct ELISA. 1) The Indirect ELISA consist mainly two antigen – antibody reactions; the first reaction is between coated antigen and primary antibody and a second reaction

the phosphate backbone of the DNA. The active site of the endonuclease perform this cleavage by binding to the side chain of certain amino acids to the phosphate group through a chemical bond. This dissolves the preexisting bond between the deoxyribose sugar and the phosphate resulting in a breakage with in the DNA chain at a specific location. (3, 7) One characteristic feature of restriction endonucleases is that they cut at a very particular site having a specific DNA sequence. This specific sequence

Vaccination coverage has been expanding for some decades, and the experiment for creating new vaccines have been conducted yet. There are approximately more than 60 kinds of vaccinations, and they can prevent 25 infectious diseases. The vaccination is advertised an effective way to develop immune system, so the people who are not over 18 years old are recommended to inoculate 15 kinds of vaccines to enhance own immunity. On the other hand, serious side effects caused by vaccinations became a social

remains perfectly all right, scientists have now discovered one vital clue to unravel the riddle. Human genome is a collection of 4 million gene switches. Some reside in bits of DNA that once were discarded as ‘junk’ but that turns out to play critical role in controlling how cells, tissues and organs behave -- the junk DNA is often referred to as the ‘dark matter’ instead. As a result of a huge project involving 440 scientists from 32 laboratories around the world, the discovery is considered as a
