Angiogenesis

Abstract Angiogenesis is an essential process for organ growth and repair. Thus, an imbalance in this process can lead to several diseases including malignancy. Angiogenesis is a critical step in vascular remodeling, tissue damage and wound healing besides being required for invasive tumor growth and metastasis. Because angiogenesis sets an important point in the control of tumor progression, its inhibition is considered a valuable therapeutic approach for tumor treatment. Chronic liver disease including hepatitis C virus (HCV) infection is one of the main cause for the development of hepatic angiogenesis and thereby plays a critical role in the modulation of hepatic angiogenesis that finally leads to hepatocellular carcinoma progression and…

The main role of PMN is phagocytosis of bacteria and tissue debri. PMNs are also a major source of cytokines, especially tumour necrosis factor-alpha (TNF-α), and second population that invades the wound consist of macrophages. The function of macrophages is phagocytosis , activation and recruitment of other cells by releasing various cytokines, growth factors such as Vascular endothelial growth Factor, Insulin like Growth Factor and Epidermal Growth Factor. Macrophages regulate matrix…

REVIEW Stroke is one of the major health problems worldwide and a leading cause of disability. But the treatment options for the management of stroke are limited. Thrombolytic reperfusion with recombinant tissue plasminogen activator (t-PA) is employed in acute phase in only less than 3% of all ischemic stroke patients while standard treatments involving rehabilitation provide some benefits for the recovery during chronic phase. However, many high-profile failures in a wide spectrum…

Idiopathic pulmonary fibrosis (IPF) – the most common form of idiopathic interstitial pneumonia – is a chronic, progressive fibrotic lung disease that affects older adults. IPF is characterized by a continuing decline in lung function, poor survival, and limited therapeutic options. The invasive proliferation of fibrous tissue and scarring of the interstitium lead to a decline in forced vital capacity (FVC) (Richeldi et al. 2014). IPF has a poor prognosis; the median survival for the disease is…

people and give them their life back. I want to use this knowledge that I will gain through this source collection and actually do something with it. I don’t just want to throw it away and never use it again. If can’t help other people maybe I can at least help myself. Throughout this project I intend to discover everything about stress the good and the bad. I intend to find out what goes on in the human body when the stress hormones are released. In some ways I intend to conquer stress and what…

brought about by angiogenesis through the vascular network. It is therefore a physiologic process important to mechanisms like wound healing, menstruation, tissue growth and embryonic development (Griffioen & Molema, 2000). Endothelial cells which line the blood vessels are in direct contact with blood. Below the layer of endothelial cells, the pericytes (structural support cells) surround the blood vessels along with fibroblasts, smooth muscle cells, extracellular membrane and basement membrane…

There are 60,000 miles worth of blood vessels in a typical adult. End to end, that would form a line that would circle the earth twice (Li). Blood vessels can create life, but blood vessels can also cause death. The abnormal development of new blood vessels is called angiogenesis, which can cause the growth of cancer tumors and lead to many other diseases. William Li, the head of the Angiogenesis foundation, focuses on research dealing with extreme or deficient angiogenesis and nutrition’s…

of lives. Folkman found two cancer inhibitors, angiostatin and endostatin, that he thinks might be a way to cure cancer. Five laboratories have also isolated their own angiogenesis inhibitors. How tumors start angiogenesis is what motivates cancer specialists to conduct cancer research. Folkman wants to see if he could…

The Nova episode, “Cancer Warrior” follows the cancer Research of Dr. Judah Folkman, and his lab’s crowning achievement, defining the role of angiogenesis in tumors. Over the years that Dr. Folkman’s lab worked on the angiogenesis project they made many breakthroughs, albeit over a long period of time. Dr. Folkman was the son of an Ohio Rabbi, but instead of going into the family business he chose to practice medicine. After graduating from medical school Dr. Folkman was drafted into the United…

In 2014, there was an estimated 1,665,540 new cancer cases diagnosed and 585,720 cancer deaths in the United States. Cancer remains the second most common cause of death in the United States, accounting for nearly 1 of every 4 deaths (American Cancer Society). Today, statistics show that 1 in every 3 Americans will be diagnosed with cancer sometime during their life (American Cancer Society). As cancer is becoming a more prevalent problem in society, there is an exceptional need for a solution.…
