Executive summary This experiment has been conducted to accumulate data on the growth of Escherichia coli (E. coli) and to monitor how it grows under certain conditions. It has been demonstrated that the levels of glucose and dissolved oxygen were found to affect the rate of growth of E. coli proportionally with a lack of oxygen resulting in the lowering of the pH. In this experiment the growth of E. coli was studied at constant temperature (37 0C) at which it grows ideally. Experimental results

Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

Introduction In this experiment‚ I measured the impact of two different topical chemicals on growing bacteria over the course of a week. Bleach‚ water‚ hand sanitizer and hand soap were all variables used to observe the effects of the bacteria swabbed from my palm and fingers. Bleach has been the go to product for killing germs and it is because of the similar effects it has with high temperature on the proteins in bacteria. I hypothesized that bleach would be the most efficient way for killing the

Introduction Allergy shots‚ also called immunotherapy‚ are a treatment used to help reduce allergy symptoms such as: Sneezing. Itchy‚ watery eyes. A runny‚ stuffy nose. Asthma. Allergy shots may benefit people who are allergic to: Grass‚ tree‚ plant‚ and weed pollens. Insect venom. Animal dander. House dust mites. Molds. Allergy shots are not given for food allergies. How do allergy shots work? When you get an allergy shot‚ the substance you are allergic to (allergen) is injected under your skin

The Industrial Revolution occurred in Britain during the mid-18th to the early 19th century. One of the most poisonous and dangerous jobs in the Industrial Revolution was matchmaking where workers would dip the ends of match sticks into a hazardous chemical called phosphorus. The prime candidates to complete the job of matchmaking were young girls aged 4-16 years old who were known as ‘match girls’. These children worked‚ making matches‚ from 6:00 in the morning to almost 10:00 at night and were

Article 76: Ayurvedic Management of Pravahika (Amoebiasis) Introduction Pravahika‚ as described in the Ayurvedic texts‚ can be compared with the dysentery. Pravahika is caused by the infection of Entamoeba histolytica‚ an Protozoan. Pravahika is diagnosed by the symptoms of diarrhoea with blood and mucus‚ flatulence‚ abdominal cramps and pyrexia. Laboratory investigations included the stool examination for the presence of amoebic cysts. Pathogenesis When Vata‚ the biological air aggravates and associates

The catalase test is used to differentiate staphylococci (catalase-positive) from streptococci (catalase-negative). The enzyme‚ catalase‚ protects the bacteria from the toxic by-products of oxygen metabolism. This enzyme is produced by bacteria that respires using oxygen. The catalase-positive bacteria include strict aerobes. Catalase-negative bacteria may be anaerobes‚ or they may be facultative anaerobes do not respire using oxygen as a terminal electron acceptor. The test reaction is very fast

While walking through my grandmother’s kitchen I saw many pill bottles and containers everywhere. I asked her why she needed to take so many pills. She sat me down and talked to me about what diabetes is‚ and how it runs through our family. After having that talk at such an early age I became interested not only in diabetes but other diseases as well. This as well as my experience shadowing a pathologist led me to the area of research known as pathology. I am applying to the Pathobiology and Translational

Saraca acoca‚ a potential candidate having a significant antimicrobial activity and widely used in the field of ayurvedic medicine. (Pradhan .P et al.‚ 2009). especially‚ used in treatment of infertility (Roya R et al.‚ 2006). The nanoparticles of silver ranges from 10-100nm and they have very high surface to volume ratio. They have very good solubility‚ stability and also excellent optical‚ electrical and thermal properties. Silver nanoparticle are off different size and shape depending on the

Giardiasis is a parasite that affects the digestive system. As a parasite‚ it feeds off another organism in order to survive. While it is uncommon in the developed world‚ it can be found in every region of the United States and around the world. It is frequently seen in developing and poor countries where it can affect a number of people due to poor hygiene and unsanitary conditions. As a parasite that can so lethally attack people‚ it displays a plethora amount of signs and symptoms in a patient
