6. EXPERIMENAL WORK 6.1 Preliminary Work 6.1.1 Collection of Plant material The leaves of Jasminum grandiflorum was collected locally in the month of July locally from Bhopal, Madhya Pradesh, India. Herbarium file of plant part was prepared and authenticated by Dr. Zia Ul Hasan (Professor, Department of Botany), Safia College Bhopal and the specimen voucher no.assigned was 344/Bot/safia/15 6.1.2 Drying and Size Reduction of Plant Material The leaves of Jasminum grandiflorum was dried under…

As years have gone by, the quality of life of human beings has been dramatically improved through the discoveries of some of history’s greatest scientific minds. A major contributor of the impact of science on the today’s world was Sir Alexander Fleming, known to most people as the “Penicillin Man.” Alexander Fleming was born in Ayrshire, Scotland, on August 6, 1881 (Biography.com Editors). Sir Alexander Fleming was a doctor and bacteriologist most notorious for his discovery of the penicillin…

such as the Gram-stain test was learned. II. Prepping/Mounting/Simple Staining Bacterial Cells Procedure: 1. Obtain 3 glass slides that are free of any foreign matter. 2. Place one drop of water on the slide. 3. Touch an inoculating loop to the petri dish of the desired bacteria and rub the loop onto the slide with the drop of water. 4. Let the slide air dry. 5. Do…

In the article, “Should Animals Be Used for Scientific or Commercial Testing?” by procon.org, it states that by testing animals with new medications and drugs it has contributed life-saving cures and treatments; in the controversy, people against animal testing believe it is a cruel and ignominious procedure. Furthermore, animals are put through an agonizing amount of pain for the scientific procedures of testing new products and drugs. They are being starved and deprived of water for multiple…

In the 1920s, A British researchers named Frederick Griffith studied bacterial pneumonia to find a vaccine for it. The specific bacteria was Streptococcus pneumoniae. Using streaking on a cultured Petri dish, the batterie was seperated into two strains, or colonies. The R-Strain was rough, and when injector into mice, it did not cause pneumonia, but the S-strain was smooth and slimy, and caused lethal pneumonia when injected. When the S-Strain was killed by heat, it did not cause sickness, but…

Sonogenetics is the use of ultrasonic soundwaves to control neurons to activate or deactivate cells. This can also be done through electrical currents or light (optogenetics). But, the issue with optogenetics, according to the website ZME Science’s article Ultrasounds used to control neurons in a worm's brain by Tibi Puiu is that light is unable to go through the body like sound can. Neuroscientists need a way to activate singular neurons reliably, specifically ones in deep inside the brain.…

Purpose: The objective is to separate the heterogeneous mixture of salt, iron filings, and salt into each pure form using filtration, evaporation, and magnetism. Background: When separating a mixture, preferably to separate a mixture that includes a soluble liquid and a insoluble solid, filtration is the best because solid molecules are bigger than liquid molecules. A filter contains pores that are small enough to let small partials though the pores while holding back the larger particles.…

of the zone of inhibition (Boyd, 2008). There may be a difference in the effectiveness of these treatments on E. coli JM101 in a Petri dish in comparison to if these materials were used in human trials. The treatments would almost certainly be broken down by the digestive tract, the properties that caused these treatments to be effective against E. coli in a Petri dish probably be absorbed and most likely would not reach the large intestine where the bacteria resides. These results would not…

Animal testing uses outdated and archaic testing procedures. In the article “Alternatives to the use of animals in research, testing and education” Jayshree Vencatesan, and advocate of Animal rights who works at Care Earth, describes how in the medical field of humane science there are three R’s every method of testing must follow. The three R’s include: replacement, refinement, and reduction. These must be used when determining alternative methods of testing. Vencatesan states that the most…
