Cancer Tumor Angiogenesis and Blood Vessels: Understanding How Tumors SpreadCancer stem cells or tumor-instating cells are responsible for the formation of tumors. These cancer cells have the ability to quickly reshape, destroy or fuse with existing blood vessels, giving them access to more nutrients and oxygen. Unfortunately, this also leads to the spread of tumors to other parts of the body through the bloodstream.Tumors release protein factors that stimulate the growth of new blood vessels, a process called tumor angiogenesis. It's important to note that this is different from angiogenesis, which is the growth of blood vessels during the healing process. By understanding how tumor angiogenesis works, we can develop new medical techniques to fight cancer and prevent its spread to other parts of the body. ... See MoreSee Less
The hypoxia is due to the following mechanism: a decrease in breathable oxygen, reduced or cardiopulmonary failure. The lungs are unable to transfer oxygen from the alveoli to the blood efficiently. If blood oxygen levels are too low, your body may not work correctly. Diseases of the blood, heart, circulation, and lungs may be the most common causes of hypoxia. ... See MoreSee Less
The sympathetic nervous system is the part of the autonomic nervous system that controls the body's fight-or-flight response. It is responsible for the body's survival instincts, preparing it to deal with danger. The sympathetic nervous system triggers the release of adrenaline and other stress hormones, which increase heart rate, breathing, and blood sugar levels. These changes give the body extra energy and strength to deal with a stressful situation. ... See MoreSee Less
Antioxidative Reactions Prooxidants are molecules that can cause oxidative stress in cells. This oxidative stress can lead to cell death or damage and several diseases. Pro-oxidants are found in both environmental and artificial substances. Some pro-oxidants are carcinogenic, and others have been linked to congenital disabilities. Signs and Symptoms of Oxidative Stress Oxidative stress likely […]
Pathogenesis Pathogenesis is the medical term for the development of a disease. It involves the interaction between a pathogen and the host, which can be a plant, animal, or human. The pathogen must be able to enter the host and multiply. The host's immune system then responds to the infection, which can lead to the […]
ROS in Cancer: What are Reactive Oxygen Species? Reactive Oxygen Species (ROS) is a phrase used to describe a number of reactive molecules and free radicals derived from molecular oxygen. These include singlet oxygen, superoxide radicals, peroxides, and hydroxyl radicals. The production of oxygen-based radicals is the bane of all aerobic species. ROS is produced […]
What is Oxidative Stress? In this article, we are going to discuss how can we reduce oxidative stress from our bodies, but first let's discuss what is oxidative stress. Oxidative stress is a condition that results when reactive oxygen species (ROS) overwhelm the cells' ability to neutralize them. ROS are natural byproducts of metabolism, but […]
Hyperbaric oxygen therapy (HBOT) It has been long known in the medical field that proper healing of the body and resistance to infection cannot occur without oxygen. Oxygen is believed to be required for all the major processes involved in wound healing, including resistance to infection, activation of fibroblasts, collagen deposition, angiogenesis, and epithelization.
