"TURMERIC: HOMEMADE WHITENING TOOTHPASTE" CHAPTER I Abstract: We are only recently becoming more aware of all the benefits of turmeric to our bodies. In addition to health benefits‚ turmeric also seems to have beauty benefits. Not only is it great for the skin‚ it also seems to whiten teeth! It is very skeptical‚ but the root plant we once thought to be only dyes to textiles can somewhat really make the teeth whiter and brighter! It sounds a little counter-intuitive to apply a rich yellow substance

important key in understanding plant biology‚ aiding this study are the fundamentals of histology and techniques in histochemistry. This experiment involved exercising free-hand sectioning techniques‚ learning maceration procedures and application of staining techniques. Sudan dye for Lipids and IKI test for starch were applied on section stem‚ root and leaf parts of Tridax procumbens. Stem cross-section of T. procumbens showed distinct ground tissues and fourteen to sixteen vascular bundles organized

inoculation‚ we were able to visibly see the various bacterial colonies of our biofilms. We proceeded to gram-stain a colony from each biofilm‚ in search of colonies of gram-positive bacteria. There are very specific steps that must be taken when gram- staining bacteria; the first step being to collect a colony of bacteria from one of the TSA plates‚ then transfer the colony from the TSA plate to the slide. We used a sterile loop (sterilized by placing the loop in the flame of a Bunsen burner to eliminate

become a Microbiologist. Microbiologists investigate the growth and characteristics of microscopic organisms such as bacteria‚ algae‚ or fungi. Medical microbiology is perhaps the most well-known because it deals with the roles that microbes have in human illness. Other types include veterinary microbiology‚ environmental microbiology‚ and food microbiology. All these deal with the way microbes or microorganisms affect animals‚ the environment‚ and the food supply. Parasites kill people every day and are

Microbiology students at the commencement of microbiology studies would be expected to have a carriage rate similar to the general population‚ therefore worth investigating whether there is evidence that the carriage rate of microbiology students is similar to hospital or age care personnel. (MLTM) The aim of this study is to determine the carriage rate of Staphylococcus aureus in the nares of second year microbiology students at RMIT University. Materials

layers of mineralised matrix. These lamellae are pink in colour which shows the eosin dye of H&E is staining this structure. This means that the lamellae of the osteons are acidophilic structures. The last structure of the osteon that can be seen in this figure is the cement line. This is a thin line that surrounds the entire osteon. It is purple in colour which shows the haemotoxylin dye of H&E is staining the cement line. This is turn means that this part of the osteon is a basophilic

To do this‚ following instructions on page 104 in the Microbiology Lab Manual‚ molten agarose was poured into a casting tray where it remained for solidification. Once solidified‚ 300 ml of a buffer was added‚ this is so the electrical field has something to pass through. Next‚ each person pipetted 5 microliters
