Exophthalmos Patient with left eye proptosis. [edit on Wikidata] Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit. Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor). Complete or partial dislocation from the orbit is also possible from trauma or swelling of surrounding tissue resulting from trauma.

Apoptosis In contrast to necrosis, which is a form of traumatic cell death that results from acute cellular injury, apoptosis is a highly regulated and controlled process that confers advantages during an organism's lifecycle.poptosis is a multi-step, multi-pathway cell-death programme that is inherent in every cell of the body. In cancer, the apoptosis cell-division ratio is altered. Cancer treatment by chemotherapy and irradiation kills target cells primarily by inducing apoptosis.

- Credit: Viktorfischer | Dreamstime. Ketosis is a temporary physical condition marked by elevated levels of compounds known as ketone bodies in the body's tissues and fluids. The term ketone bodies refers to three different biochemicals: acetoacetate, beta-hydroxybutyrate and acetone.

Bulging Eyes (Proptosis) â Symptoms & Treatment The bulging orbit may increase the intraocular pressure behind and inside the eye. As the intraocular pressure increases, so do risks for other eye diseases such as glaucoma. There are many different names experts use when referring to bulging eyes, such as: Proptosis.

Apoptosis Viral induction of apoptosis occurs when one or several cells of a living organism are infected with a virus, leading to cell death. Cell death in organisms is necessary for the normal development of cells and the cell cycle maturation. It is also important in maintaining the regular functions and activities of cells.nhibition of apoptosis can result in a number of cancers, autoimmune diseases, inflammatory diseases, and viral infections. It was originally believed that the associated accumulation of cells was due to an increase in cellular proliferation, but it is now known that it is also due to a decrease in cell death.

What is apoptosis? There are two ways that a cell can die: necrosis and apoptosis. Necrosis occurs when a cell is damaged by an external force, such as poison, a bodily injury, an infection or getting cut off from the blood supply (which might occur during a heart attack or stroke).ecrosis occurs when a cell is damaged by an external force, such as poison, a bodily injury, an infection or getting cut off from the blood supply (which might occur during a heart attack or stroke).

Exophthalmos (May 2010). Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit. Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor).n the case of Graves' disease, the displacement of the eye is due to abnormal connective tissue deposition in the orbit and extraocular muscles which can be visualized by CT or MRI. If left untreated, exophthalmos can cause the eyelids to fail to close during sleep leading to corneal dryness and damage.

What Is Ketosis? That depends. Ketosis is a normal metabolic process, something your body does to keep working. When it doesn't have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones.

Bulging Eyes (Proptosis) â Symptoms & Treatment Michael Garin O.D. Proptosis, or exophthalmos, is the bulging out of one eye (unilateral) or both eyes (bilateral). Cases of proptosis develop for reasons ranging from variations in our anatomy to the development of another condition such as hyperthyroidism, of which bulging eyes are a symptom. If a person suddenly develops exophthalmos, especially in both eyes, it is considered a very serious problem. Sudden onsets of proptosis should always be evaluated by an eye doctor immediately. In mild cases of proptosis, a doctor can take measurements with a special ruler known as an exophthalmometer. If measurements are within a certain range, more testing is unnecessary.

Amitosis Amitosis is also referred to as Binary fission or direct division. This type of division is employed by lower prokaryotes, not only for multiplication of cells but also for reproduction. In this context, a bacterial cell has been taken as an example of describe the process.

Eyes, Bulging Bulging or protruding of one or both eyes is called proptosis or exophthalmos. Exophthalmos is usually used when describing bulging eyes caused by Graves disease, a disorder causing overactivity of the thyroid gland (hyperthyroidism). Bulging eyes are not the same as prominent eyes.

Ketosis: What is ketosis? Stored fats are broken down for energy, resulting in a build-up of acids called ketones within the body. Ketosis is a metabolic process that occurs when the body does not have enough glucose for energy.

Apoptosis, or Programmed Cell Death, is key to  multicellular life and multicellular computing The apoptosis mechanism removes the cell with a minimum of risk or damage to nearby cells. Apoptosis shrinks the cell, degrades the DNA in its nucleus, breaks down the mitochondria, and then breaks the cell into small, neat, membrane-wrapped, fragments. Finally, nearby phagocytic cells engulf the cell fragments.

- Prophase (from the Greek πρό, before and φάσις, stage) is a stage of mitosis and of meiosis. In this article the prophase stage of mitosis is described. See Wikipedia article Meiosis for a description of the more complex prophase stage during meiosis. During mitosis, prophase is when the chromatin condenses into two rod-shaped structures called chromosomes in which the chromatin becomes visible.

- Apoptosis is programmed cell death or cell suicide. It is mainly initiated by the cutting off a portion of the inactive procaspases to make active caspases, which are proteins that speed up chemical reactions that start degrading parts of the cell and are the most important activator of cellular destruction.

- In children, unilateral proptosis is often due to an orbital cellulitis–type picture, and, in bilateral cases, neuroblastoma and leukemia are more likely. Other causes in children include rhabdomyosarcoma, retinoblastoma, capillary hemangioma, dermoid cyst, glioma of the optic nerve, and metastatic disease.

apoptosis (āp'əp-tō'sĭs, āp'ə-tō'-) A natural process of self-destruction in certain cells, such as epithelial cells and erythrocytes, that are genetically programmed to have a limited life span or are damaged. Apoptosis can be induced either by a stimulus, such as irradiation or toxic drugs, or by removal of a repressor agent.
