BACTERIAL MENINGITIS BY JAY DOMANTAY JAY DOMANTAY ANATOMY 151 HERBERT MAY 11‚ 2009 BACTERIAL MENINGITIS A bacterial infection of blood poisoning in the meninges called bacterial meningitis affects toddlers‚ adolescents and young adults. The infection strikes nearly 3‚000 Americans each year‚ and 10 to 12% of those infected will die. Among those who survive‚ approximately 20 % live with permanent disabilities‚ such as brain damage‚ kidney disease‚ hearing loss or loss of limbs.(“Prevention

conjunctivitis can occur in one or two of a person’s eyes. It tends to cause a watery discharge while conjunctivitis caused by bacteria causes a thicker discharge. Both are transmitted to another eye in the discharge. Children are primarily affected by bacterial conjunctivitis‚ possibly because it is more transferable in a location like school. People are at a higher risk of developing conjunctivitis if they use contacts. Those who come in

Bacterial biosensors for victual processing The biosensor research has blossomed into a mature and highly active field over the past 20 years‚ mutually in the laboratory and in the business-related district‚ attract huge attention due to the pledge of holdings for vital aspects of the human life. The wished-for work aims to engineer a capacitive biosensor‚ which will be able to perform label-free and fast electrochemically immune-detection based on very small biological samples. This

Lauren Seymour- Growth and Decay Procedure: For the growth part of this lab‚ we started with 4 M&M’s in the cup. We shook the cup and poured the M&M’s onto a napkin. Then‚ we counted the number of M&M’s that had the “M” facing up. Next we added a new M&M for each one that was facing up and continued this process until all of our M&Ms were used (11 trials). For the decay section of this lab we began with a full cup of M&Ms. We shook the cup and poured all of the M&M’s

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Cellulitis is a bacterial infection that affects the skin and the tissue underneath the skin. Although cellulitis can be caused by many types of bacteria‚ streptococcus and staphylococcus are the main bacteria that cause this condition. Cellulitis often develops near surgical wounds or ulcers. This condition causes the skin to become reddened and swollen. It also causes the area to feel tender and hot. Cellulitis can quickly spread to other areas of the body. It is not contagious. Cellulitis can

OBSERVATION OF BACTERIAL CELLS VIA MICROSCOPE In this experiment‚ we have learned several basic molecular biology techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained

for the plant. Also‚ overwatering can kill the seed by drowning it and making its tissue fragile to rotting‚ not even growing the plant. From these researched observations‚ it can be assumed that the in-between amounts of water are favorable to the growth of the seed and plant lifespan. Hypothesis: The intermediate amounts of water will grow the plants the best‚ since too little water won ’t grow the plant much and too much will drown the seed. Method: To begin this experiment‚ you need to
