Aedes aegypti

In 1956, Francis Crick first described what he called “The central dogma of molecular biology.” This essentially describes the flow of genetic information within cells. It states that DNA is transcribed into RNA with the help of an RNA polymerase enzyme. The RNA is then translated into a protein by protein synthesis. One thing that could drastically alter the genetic information within cells is a process called gene silencing. This process regulates the gene expression of certain genes and can

Veronica Moreno Professor: Jankowski, Ph.D. Developmental psy- PSY441B Spring 2016 Pregnancy is a very difficult time in a women’s life, everything that is digested, breathed, and felt affects the fetus. Teratogens are factors that cause developmental problems of an embryo. These factors include stress; toxin such as drug and cigarette use, the health and even the age of the mother can have an impact on the development of the fetus. Teratogen can cause birth defect that may lead to life

Epidemics of the 19th century were faced without the improved medical technologies that made the 20th and 21st-century epidemics rare and less lethal. It was in the 18th century that micro-organisms (viruses and bacteria) were discovered, but it was not until the late 19th century that the experiments of Lazzaro Spallanzani and Louis Pasteur disagreed with the spontaneous generation argument conclusively, crediting the germ theory and Robert Koch 's discovery of micro-organisms as the cause of disease

Her infection began when she was bitten by a mosquito which was seeking her protein-rich blood to nourish its eggs. As part of the process of sucking the droplet of blood from the girl, the mosquito, simultaneously injected saliva to ease the flow of blood into its proboscis. Malaria-causing pathogens gathered in the mosquito’s salivary glands and traveled into the girl’s body. Once in the body, the wormlike parasites moved to the girl’s liver to embed themselves allowing them to feed and multiply

This type of mosquito that usually carries the yellow fever is called Aedes aegypti. Among the two kinds, urban yellow fever is the cause of most yellow fever outbreaks. The symptoms of yellow fever are varied. The virus has an incubation period of three to six days. The first symptoms will be fever, muscle pain, backache, headache

The 1878 yellow fever epidemic in Memphis proved to be fatal, killing almost all who got infected. The disease traveled up from New Orleans infecting and killing many on its way. Memphis was going through reconstruction and was becoming the center for merchants and travelers. Furthermore, Memphis began to become overly populated only increasing the devastation that would be caused by the yellow fever. This was a confusing period were even medical professionals did not know where the disease came

The Demon In The Freezer Christopher Coble C. K. King High School Abstract The first major bioterror event in the United States--the anthrax attacks in October 2001--was a clarion call for scientists who work with "hot" agents to find ways of protecting civilian populations against biological weapons. In The Demon in the Freezer, his first nonfiction book since The Hot Zone, a #1 New York Times bestseller, Richard Preston takes us into the heart of Usamriid, the United States Army Medical Research
