What is a CD4 cell or T-cell? CD4 cells or T-cells are the “generals” of the human immune system. These are the cells that send signals to activate your body’s immune response when they detect “intruders‚” like viruses or bacteria. Because of the important role these cells play in how your body fights off infections‚ it’s important to keep their numbers up in the normal ranges. This helps to prevent HIV-related complications and opportunistic infections. For more information‚ see the National Cancer

The Cell Extraction In the dangerous occupation of a correctional professional the “cell extraction” is something that will happen. People can get angry if they don’t get their way. I say people because inmates are people‚ that got into trouble. As a correctional professional I can use the “cell extraction” to move an incompliant inmate from one cell to a more secured cell. This is something I am good at. I have to be. It is my job. The first time that I required an extraction team to suit up

The nucleus is a large membrane bound organelle. Most cells have a single nucleus though skeletal muscle can have more than one (multinucleate) or some cells such as red blood cells have no nucleus. The nucleus contains the genetic material and is where DNA replication and RNA transcription occur. The nucleus is bound by a membrane which contains nuclear pores. These pores allow RNA molecules and proteins to move in and out of the nucleus. However‚ this process is selective and is energy dependent

Abstract Transitional age youth between the ages of 15-18 who are battling chronic illnesses such as Sickle Cell Disease (SCD) traditionally have a hard time coping to their life style.

The prison cell walls are cold hard concrete walls‚ they are rough too the touch‚ the smell of concrete dust from the carving of the previous cellie fills the air. The three concrete walls and the metal barred door are more intimidating that a hungry grizzly bear finding his first meal in months. You never get used to the metal barred door slamming behind you‚ it just sends a chill down your spin like you’re in the middle of a frozen lake and the thin ice is slowly cracking beneath you.

bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment. The fluid and all its dissolved or suspended particles that can be found within a bacterial cell are called the Cytoplasm.

People affected with sickle cell disease produce abnormally shaped red blood cells that causes health problems. Sickle cell disease is caused by a defective gene passed on from the parent to the child. Sickle cell disease is condition that is considered serious and lifelong. People of African descent are mainly affected with sickle cell disease in addition to ‚ Caribbean‚ Middle Eastern‚ Eastern Mediterranean
