Antigen

It’s made up of a network of cells, tissues and organs that work together to protect the body. One of the important cells in this system are leukocytes, or white blood cells. They’re stored in the thymus, spleen, and bone marrow. When antigens are detected, cells trigger B-cells to produce antibodies. T-cells destroy any antibodies that have become infected or somehow changed. All of these cells offer the body protection against disease (Nemours 1). These are the body systems the influenza…

An estimated 1.4 million blood donations are annually assimilated by The Australian Red Cross Blood Service (ARCBS) in Australia alone. ARCBS uses this picture as propaganda to persuade the adult audience to aid hospital patients by donating blood. The message of this ad is that ARCBS is majorly in need of blood contributions and also of money. The significance of this ad is to be able to reveal to the audience the desperate need of blood and money donations The purpose of this image is to…

mediate the association between viral GPs and the nucleocapsid [2]. The L gene codes for an RNA dependent RNA polymerase [2]. In creating a vaccine to fight against Ebola, targeting these viral proteins and inhibiting their functions or utilize them as antigen presenters may produce viable vaccines. Various vaccines currently under development are targeting such…

civilizations have are unjust and should be reconsidered. Antigone's love for her brother, Haemon's anger at his father, and Creon’s Pride are all examples of how acting on emotion and not fully thinking about one's actions can cause many negative affects. Antigens love for polyneices causes many problems for not only herself but also for others. “Take this hand of mine to bury the dead…challenge Creon to his face” (195) Although Antigone knows burying her brother is civilly wrong, she still…

DNA paternity testing works by drawing a comparison between a child's DNA profile and the equivalent profile of a presumed father. As any child's DNA will be made up of half from each biological parent, by comparing the two sets of DNA, scientists are then able to see what similarities may have been inherited. Whenever a parent and child are proven biologically related, then their DNA profiles will show perceptible patterns that mark them out as part of the same family. Depending upon…

HIV is the Human immunodeficiency virus. The virus was recognized in a chimpanzee by scientist in Africa. They believe that it is the same cause of HIV infections found in humans. The type of infection found in chimpanzees are called the simian immunodeficiency virus that was spread to humans and also mutated into HIV. There was a time when human hunted chimpanzee for meat and was in contact with their blood that is infected. In past studies it showed that HIV have showed up in apes and…

Sarah Diaz Dr. Basu Bio 572 My Favorite gene One of my favorite genes that I have had the pleasure of working with is known as PROMININ-1, or PROM-1. One of the reasons why it exists as my favorite gene, is because the research lab that I am interning at studies this gene and its role in a very well known and unfortunate disease, biliary atresia. It also is one my favorites due to the fact that it has a lot of potential applications in studying other diseases or further research. These…

Hypothalamic programming of systemic ageing involving IKK-b, NF-kB and GnRH (Zhang et al., 2013). Cellular senescence is when a cell’s replicative mechanism becomes arrested. This was phenomenon was first described in Hayflick’s experiment. Cellular senescence is usually due to protect the cell from becoming cancerous but it also plays a prominent role in aging (van Deursen, 2014). While senescence describes a halt in proliferation, cancer development is the uncontrolled proliferation of…

Diseases take the lives of millions each year but, with medicine and the proper procedures, they can be prevented and cured. Vaccines can successfully help prevent and cure many common diseases such as the flu, measles, and many others. Additionally, vaccines work together with the immune system to build an immunity against other diseases. But, like everything else in life, vaccines have both benefits and risks. Body Paragraph 1: To start with, vaccines are shots that have a weakened or dead…

1. Point A is considered the S1 area of the graph. At this point in the graph is where the sound “lubb” is heard. At this point is when the AV closes and the semilunar valve closes. 2. Point D is at the S2 area. This is where the “dub” sound is made. This is the beginning of ventricular filling where the AV valves open. 3. At the end of the atrial systole, the ventricles have a maximum amount of blood that each can carry. The quantity of this is known as the end- diastolic volume. 4. In S2 is…
