Cellular Anastasis
Anastasis is a cellular phenomenon characterized by recovery of cells threatened by cell death; it essentially reverses the process of programmed cell death, or apoptosis. Contrary to the prior assumption that apoptosis is irreversible, some cells have been discovered to resist the stimuli that trigger apoptosis. Some of these cells can survive even following the activation of Caspase#Apoptosis, executioner caspases, forming the basis of anastasis. The initial phase of recovery begins when Transcription (biology), transcription is initiated and the cell recovers from previous stressors. Finally, the cell's cytoskeleton undergoes reorganization, reinforcing its structure and encouraging Cell migration, migration. The relatively recent discovery of anastasis is a key factor in the survival of cancer cells exposed to chemotherapy and changed the way scientists approach the topic of cell death. Anastasis is possible even during advanced stages of cell death, leading researchers to believe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Death
Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part. Apoptosis or Type I cell-death, and Autophagy (cellular), autophagy or Type II cell-death are both forms of programmed cell death, while necrosis is a non-physiological process that occurs as a result of infection or injury. The term "cell necrobiology" has been used to describe the life processes associated with morphological, biochemical, and molecular changes which predispose, precede, and accompany cell death, as well as the consequences and tissue response to cell death. The word is derived from the Greek language, Greek νεκρό meaning "death", βìο meaning "life", and logos, λόγος meaning "the study of". The term was initially coined to bro ...

Phagocyte
Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. Their name comes from the Greek ', "to eat" or "devour", and "-cyte", the suffix in biology denoting "cell", from the Greek ''kutos,'' "hollow vessel". They are essential for fighting infections and for subsequent immunity. Phagocytes are important throughout the animal kingdom and are highly developed within vertebrates. One litre of human blood contains about six billion phagocytes. They were discovered in 1882 by Ilya Ilyich Mechnikov while he was studying starfish larvae.Ilya Mechnikov retrieved on November 28, 2008. Fro ''Physiology or Medicine 1901–192 ...

HeLa Cells Stained With Antibody To Actin (green) , Vimentin (red) And DNA (blue)
HeLa () is an immortalized cell line used in scientific research. It is the oldest human cell line and one of the most commonly used. HeLa cells are durable and prolific, allowing for extensive applications in scientific study. The line is derived from cervical cancer cells taken on February 8, 1951, from Henrietta Lacks, a 31-year-old African American mother of five, after whom the line is named. Lacks died of cancer on October 4, 1951. The cells from Lacks's cancerous cervical tumor were taken without her knowledge, which was common practice in the United States at the time. Cell biologist George Otto Gey found that they could be kept alive, and developed a cell line. Previously, cells cultured from other human cells would survive for only a few days, but cells from Lacks's tumor behaved differently. History Origin In 1951, Henrietta Lacks was admitted to the Johns Hopkins Hospital with symptoms of irregular vaginal bleeding; she was subsequently treated for cervical ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

DNA Damage
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. A weakened capacity for DNA repair is a risk factor for the development of cancer. DNA is constantly modified in cells, by internal metabolic by-products, and by external ionizing radiation, ultraviolet light, and medicines, resulting in spontaneous DNA damage involving tens of thousands of individual molecular lesions per cell per day. DNA modifications can also be programmed. Molecular lesions can cause structural damage to the DNA molecule, and can alter or eliminate the cell's ability for transcription and gene expression. Other lesions may induce potentially harmful mutations in the cell's genome, which affect the survival of its daughter cells following mitosis. Consequently, DNA repair as part of the DNA damage response (DDR) is constantly active. When normal repair processes fail, including apoptosis, irreparable DNA damage may occur ...

Jesus
Jesus (AD 30 or 33), also referred to as Jesus Christ, Jesus of Nazareth, and many Names and titles of Jesus in the New Testament, other names and titles, was a 1st-century Jewish preacher and religious leader. He is the Jesus in Christianity, central figure of Christianity, the Major religious groups, world's largest religion. Most Christians consider Jesus to be the Incarnation (Christianity), incarnation of God the Son and awaited Messiah#Christianity, messiah, or Christ (title), Christ, a descendant from the Davidic line that is prophesied in the Old Testament. Virtually all modern scholars of classical antiquity, antiquity agree that Historicity of Jesus, Jesus existed historically. Accounts of Life of Jesus, Jesus's life are contained in the Gospels, especially the four canonical Gospels in the New Testament. Since the Age of Enlightenment, Enlightenment, Quest for the historical Jesus, academic research has yielded various views on the historical reliability of t ...

Resurrection
Resurrection or anastasis is the concept of coming back to life after death. Reincarnation is a similar process hypothesized by other religions involving the same person or deity returning to another body. The disappearance of a body is another similar but distinct belief in some religions. With the advent of written records, the earliest known recurrent theme of resurrection was in Egyptian and Canaanite religions, which had cults of dying-and-rising gods such as Osiris and Baal. Ancient Greek religion generally emphasised immortality, but in the mythos, a number of individuals were made physically immortal as they were resurrected from the dead. The universal resurrection of the dead at the end of the world is a standard eschatological belief in the Abrahamic religions. As a religious concept, resurrection is used in two distinct respects: # a belief in the ''individual resurrections'' of individual souls that is current and ongoing (e.g., Christian idealism, realized e ...

Ethanol
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula . It is an Alcohol (chemistry), alcohol, with its formula also written as , or EtOH, where Et is the pseudoelement symbol for ethyl group, ethyl. Ethanol is a Volatility (chemistry), volatile, flammable, colorless liquid with a characteristic wine-like odor and pungent taste. As a psychoactive depressant, it is the active ingredient in alcoholic beverages, and the second most consumed drug globally behind caffeine.
