Optical Metabolic Imaging Measures Drug Toxicity Fuyao Chen, Joe Sharick, Tiffany Heaster, Melissa Skala Vanderbilt University, Department of Biomedical Engineering, Station B, Box 1631, Nashville, Tennessee 37235, United States Abstract Regulatory agencies, such as the US Environmental Protection Agency, face a daunting task in determining potential human health risks (e.g. birth defects, cancer, and neurological disorders) associated with thousands of commonly used chemicals. The gold standard

It is estimated that this year, about 28,630 people in the United States only could be diagnosed with a tumor. 23,800 of those people are adults, and 4,830 are children. And that is just this year. Who knows how many people will be diagnosed with a tumor next year, or the year after that. Tumors are a problem that we need to stop. A tumor is an abnormal growth of tissues in the body. They can grow from any kind of tissue in the body, such as; bones, blood vessels, nerves, or any organ. There are

Gamma radiation is a high frequency form of wave located to the far right of the electromagnetic spectrum. It is often associated with alpha and beta radiation. It is an ionizing radiation like the x-ray but it differs in its original. Compared to alpha and beta radiation, gamma rays have the highest power of penetration. It can go through a thick sheet of lead, and it has a nearly endless range in air and travels at the speed of light (which is x10^8m/s). Therapeutic Use of Gamma Rays Oncologists

Obtaining an accurate pathologic diagnosis can be challenging, however. Many characteristic features on histologic examination of melanomas aid in the diagnosis, but there is currently no single feature that is pathognomic for the disease. Histologic examination of melanoma classically shows cytologic atypia with enlarged cells with aberrant, large, pleomorphic, hyperchromic nuclei and prominent nucleoli in company of increased mitotic activity. A pagetoid growth pattern with upward growth of the

Leukaemia What is cancer? Cancer occurs when in the body abnormal cells starts growing rapidly and gets out-of-control. Usually, normal cells grow, divide into more cells and die in the end. When people are at their early ages of life, the normal cells divides more quickly until we start growing into adults. Later, the cells in most parts of the body splits only when a replacement is needed to the worn-out or dying cells and or to repair injuries. Cancer cells are different from normal cells,

Cognitive changes with cancer patient and cancer treatment especially chemotherapy have become an important issue which can be dating back to 1980s but the researchers paid attention to this topic at the mid of 1990s and many studies conducted to discuss the relationship between chemotherapy and cognitive changes among cancer patient treated by chemotherapy. Two studies conducted in 2012 and 2015 to find out the relation between chemotherapy and cognitive function. Concluded that the cognitive dysfunction

DFSP Prognosis By Liji Thomas, MD Dermatofibrosarcoma protuberans (DFSP) is a rare type of cancer in which a soft tissue sarcomatous tumor forms deep in the skin. It begins as a small flat lesion, rarely more than 5 cm across, with neither pain nor tenderness. It may be flesh-colored, but more often reddish or purple. The tumor is characteristically a slow-growing one, and takes months or years to become a raised nodule. Most DFSP tumors occur in individuals between the ages of 20 and 50 years,

Tumor metastasis, is a major case of cancer-associated mortality, with dissemination of circulating tumor cells (CTCs) primarily occurring through the cardiovascular system.1 Therefore CTCs have a promising clinical potential as biomarkers and therapeutic targets to predict disease progression, survival in metastatic cancer, and early-stage cancer diagnosis.1,2 Due to the various distribution of CTCs within the cardiovascular system, blood samples may need to be collected from various sites according

Question 1 Figure 3 is difficult to interpret because it seems to be missing a group. What group seems to be missing? How would the inclusion of this group aid in the interpretation of this figure? Answer: The authors used 1mM of melatonin, dissolved in 50% of PBS and 50% buffer solution, as the melatonin treatment for cancer stem cell viability assay. The data obtained from melatonin treatment was compared with a control group. However, they did not mention the treatment condition of control group

Tumor marker are substances that are produced by cancer to make a tumor found in your blood. They are produced in a much higher cancer level. It could be found in blood, urine, tumor tissues or other tissues if the patient have cancer. Tumor markers are proteins. Most are associated with one cancer. There is a bone test. A bone test when they determine if your bones are damaged either from cancer or some other cause. The scan will detect if you have cancer in your bones. People don’t usually have
