Atlas of Genetics and Cytogenetics in Oncology and Haematology List of cognitive biases Cognitive biases are systematic patterns of deviation from norm or rationality in judgment, and are often studied in psychology and behavioral economics.[1] There are also controversies over some of these biases as to whether they count as useless or irrational, or whether they result in useful attitudes or behavior. For example, when getting to know others, people tend to ask leading questions which seem biased towards confirming their assumptions about the person. However, this kind of confirmation bias has also been argued to be an example of social skill: a way to establish a connection with the other person.[8] Although this research overwhelmingly involves human subjects, some findings that demonstrate bias have been found in non-human animals as well. Decision-making, belief, and behavioral biases[edit] Many of these biases affect belief formation, business and economic decisions, and human behavior in general. Social biases[edit] Memory errors and biases[edit] See also[edit] [edit]

Cell Cycle: An Interactive Animation During development from stem to fully differentiated, cells in the body alternately divide (mitosis) and "appear" to be resting (interphase). This sequence of activities exhibited by cells is called the cell cycle. Follow the events in the entire cell cycle with the following animation. Interphase: Interphase, which appears to the eye to be a resting stage between cell divisions, is actually a period of diverse activities. Gap 0 (G0): There are times when a cell will leave the cycle and quit dividing. Gap 1 (G1): Cells increase in size in Gap 1, produce RNA and synthesize protein. S Phase: To produce two similar daughter cells, the complete DNA instructions in the cell must be duplicated. Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. Mitosis or M Phase: Cell growth and protein production stop at this stage in the cell cycle. Cancer cells reproduce relatively quickly in culture.

Phases of Mitosis in Plant and Animal Cells Cell Division Overview Clockwise, from top left: embryonic sea urchin cells, frog skin cells, neuron, 8-cell fish embryo. All of the living organisms on Earth are made up of one or more cells, which are the simplest units of life capable of independent existence and reproduction. Cells have the extraordinary ability to make nearly identical copies of themselves by the process of cell division. Since new cells are only produced by existing cells, cell division is essential for the continuation of life. There are a variety of reasons that might cause a cell to divide: Multicellular organisms grow in size and complexity by making more cells. Two events are required for successful cell reproduction. The second requirement is the partitioning of cytoplasm between the two daughter cells. The Cell Cycle The orderly program of events in the lifetime of a cell is known as the cell cycle. The Phases of Mitosis Compare and contrast mitosis in the following plant and animal cell pictures: Prophase Anaphase

Stages of Colorectal Cancer with Dukes and TNM staging system | Health Topics 1. Older colorectal cancer stages is based on Dukes staging system. Stage 1: (Dukes'A): 0) lesions limited to mucosal layer (carcinoma in situ). 1) invasion and submucosal lesions. 2) muscular lesion invading the intestinal wall. Stage 2 (Dukes'B): lesions and serosal invasion, or invasion and the surrounding tissues and organs, but en bloc resection can be together. Stage 3 (Dukes'C): 1) with lesions near the lymph node metastasis (refer to the side or on the edge of blood vessel wall adjacent to lymph node metastasis). 2) with the supply of blood vessels and mesangial margin near the lymph node metastasis. Stage 4 (Dukes'D): 1) with distant organ metastasis (such as liver, lung, bone, brain metastasis, etc.). 2) with distant lymph node metastasis (such as the supraclavicular lymph node metastasis, etc.), or the supply of blood vessels can not be the root of all lymph node metastasis resection. 2. T: The degree of invasion of the intestinal wall T0 - no evidence of tumor N0 - no lymph nodes involved

Staging and Grading Cancer If left untreated, cancers often go through three stages: 1. Local growth and damage to nearby tissues Cancer cells multiply quickly. A cancerous (malignant) tumour is a lump or growth of tissue made up from cancer cells. Cancerous tumours normally first develop in one site - the primary tumour. Cancer cells also have the ability to push through or between normal cells. 2. Some cancer cells may get into local lymph channels. 3. Some cancer cells may get into a local small blood vessel (capillary). There are more than 100 different types of cancer. Carcinomas are cancers that arise from cells which line a body surface, or the lining of a gland - for example, the skin, or the lining of the gut, mouth, cervix, airways, etc.Sarcomas are cancers that arise from cells which make up the connective tissues such as bones or muscles. The five most common cancers in the UK are: breast, lung, prostate, bowel and skin cancer. Staging is a way of describing how much a cancer has grown and spread.
