First identified in hematological malignancies‚ CSCs are now thought to play an important role in a wide variety of solid tumors such as NSCLC‚ breast and colorectal cancer. The role of CSCs in driving tumor formation illustrates the dysregulation of differentiation in tumorigenesis. The Wnt‚ Notch

Henrietta’s cells were placed in this device‚ they never stopped dividing. While their research value is unquestioned‚ the tumor cells had created havoc in Henrietta Lacks’ body. Skloot recounts the lab technician Mary Kubicek who was present at the autopsy. “The tumors had completely blocked her urethra‚ leaving doctors unable to pass a catheter into her bladder to empty it. Tumors the size of baseballs had nearly replaced her kidneys‚ bladder‚ ovaries and uterus. And her other

BASIC CONCEPTS ENDOCRINE SYSTEM :- In physiology‚ the endocrine system is a system of glands‚ each of which secretes a type of hormone into the bloodstream to regulate the body. It derives from the Greek words endo meaning inside‚ within‚ and crinis for secrete. The endocrine system is an information signal system like the nervous system. Hormones are substances (chemical mediators) released from endocrine tissue into the bloodstream that attach to target tissue and allow communication among

Crazy Lady Cancer NRS 410v January 25‚ 2014 Cancer Cancer is a disease with no regard for age‚ gender‚ or ethnicity. In 2013 nearly 1‚600 people a day died from cancer; and “cancer remains the second most common cause of death in the US” (ACS‚ 2013). There are twenty three cancer types currently identified. However‚ many people still do not understand what a diagnosis of cancer means‚ how cancer progresses‚ or the common complications with cancer. All valuable information

topic will be discussed. “Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of exposed tissue leading to cellular death. To spare normal tissues (such as skin or organs which radiation must pass through to treat the tumor)‚ shaped radiation beams are aimed from several angles of exposure to intersect at the tumor‚ providing a much larger absorbed dose there than in the surrounding‚ healthy tissue

The human body‚ like most living organisms‚ needs energy to survive. Specifically‚ the lungs play an important role in the body’s energy production through gas exchange. Gas exchange occurs in the alveoli of the lungs when the body breathes in air. In this process‚ a cell’s mitochondria burns the oxygen from the air‚ converting it into ATP‚ also known as energy‚ and yields carbon dioxide and water that the body exhales. Because energy is vital to survival‚ it is necessary for the organs that
