Vitality
Vitality (, , ) is the capacity to live, grow, or develop. Vitality is also the characteristic that distinguishes life, living from non-living things. To experience vitality is regarded as a basic psychological drive and, in philosophy, a component to the will to live. As such, people seek to maximize their vitality or their experience of vitality—that which corresponds to an enhanced physiological capacity and mental state. Overview The pursuit and maintenance of health and vitality have been at the forefront of medicine and natural philosophy throughout history. Life depends upon various biological processes known as vital processes. Historically, these vital processes have been viewed as having either mechanistic or non-mechanistic causes. The latter point of view is characteristic of vitalism, the doctrine that the phenomena of life cannot be explained by purely chemical and physical mechanisms. Prior to the 19th century, theoreticians often held that human Life expec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Vitality
Urban vitality is the quality of spaces in urban area, cities that attract diverse groups of people for a range of activities at different times of the day. Such spaces are often be perceived as being alive, lively or vibrant, in contrast with low-vitality areas, which may repel people and be perceived as unsafe. The urban vitality index is a measure of this quality and has become a fundamental tool in urban planning, especially in interventions for spaces with low vitality. The index is also used to assist the management of spaces that already have high vitality. However, the success of high-vitality spaces can sometimes lead to gentrification and overtourism that may reduce their vitality and initial popularity. The concept of urban vitality is based on the works of Jane Jacobs, especially her most influential work, ''The Death and Life of Great American Cities''. In the 1960s, Jacobs criticized the modern architecture, modern and rationalist architecture of Robert Moses and Le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jīvitindriya
Jīvitindriya (Sanskrit and Pali) is a Buddhism, Buddhist term translated as "life faculty" or "vitality". ''Jīvitindriya'' is identified as one of the Mental_factors_(Buddhism)#Seven_universal_mental_factors, seven universal mental factors within the Theravada abhidharma teachings. In this context, ''jīvitindriya'' is defined as a Mental factors (Buddhism), mental factor that sustains the life of the citta (mind) and other mental factors it accompanies. The characteristic of jīvitindriya is said to be “ceaseless watching”. Definition Theravada Bhikkhu Bodhi states: :There are two kinds of life faculty, the mental, which vitalizes the associated mental states, and the physical, which vitalizes material phenomena. The mental life faculty alone is intended as a cetasika. It has the characteristic of maintaining the associated mental states, the function of making them occur, manifestation as the establishing of their presence, and its proximate cause is the mental states to be ...

Philosophy Of Life
(; meaning "philosophy of life") was a dominant philosophical movement of German-speaking countries in the late 19th and early 20th centuries, which had developed out of German Romanticism. emphasised the meaning of life, meaning, value and purpose of life as the foremost focus of philosophy. Its central theme was that an understanding of life can only be apprehended by life itself, and from within itself. Drawing on the critiques of epistemology offered by Schopenhauer and Nietzsche, notable ideas of the movement have been seen as precursors to both Husserlian Phenomenology (philosophy), phenomenology and Heideggerian existential phenomenology. criticised both mechanism (philosophy), mechanistic and materialist approaches to science and philosophy and as such has also been referred to as the German vitalist movement, though its relationship to vitalism, biological vitalism is questionable. Vitality in this sense is instead understood as part of a biocentrism (ethics), biocen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hinduism
Hinduism () is an Hypernymy and hyponymy, umbrella term for a range of Indian religions, Indian List of religions and spiritual traditions#Indian religions, religious and spiritual traditions (Sampradaya, ''sampradaya''s) that are unified by adherence to the concept of ''dharma'', a Ṛta, cosmic order maintained by its followers through rituals and righteous living, as expounded in the Vedas. The word ''Hindu'' is an exonym, and while Hinduism has been called the oldest religion in the world, it has also been described by the modern term ''Sanātana Dharma'' () emphasizing its eternal nature. ''Vaidika Dharma'' () and ''Arya dharma'' are historical endonyms for Hinduism. Hinduism entails diverse systems of thought, marked by a range of shared Glossary of Hinduism terms, concepts that discuss God in Hinduism, theology, Hindu mythology, mythology, among other topics in Hindu texts, textual sources.

Aging
Ageing (or aging in American English) is the process of becoming Old age, older until death. The term refers mainly to humans, many other animals, and fungi; whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal. In a broader sense, ageing can refer to single cells within an organism which have Cellular senescence, ceased dividing, or to the Population ageing, population of a species. In humans, ageing represents the accumulation of changes in a human being over time and can encompass physical, psychological, and social changes. Reaction time, for example, may slow with age, while memories and general knowledge typically increase. Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes. Current Theory of aging, ageing theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail, or to the p ...

Natural Philosophy
Natural philosophy or philosophy of nature (from Latin ''philosophia naturalis'') is the philosophical study of physics, that is, nature and the physical universe, while ignoring any supernatural influence. It was dominant before the development of modern science. From the ancient world (at least since Aristotle) until the 19th century, ''natural philosophy'' was the common term for the study of physics (nature), a broad term that included botany, zoology, anthropology, and chemistry as well as what is now called physics. It was in the 19th century that the concept of science received its modern shape, with different subjects within science emerging, such as astronomy, biology, and physics. Institutions and communities devoted to science were founded. Isaac Newton's book '' Philosophiæ Naturalis Principia Mathematica'' (1687) (English: ''Mathematical Principles of Natural Philosophy'') reflects the use of the term ''natural philosophy'' in the 17th century. Even in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitalism
Vitalism is a belief that starts from the premise that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things." Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy", "'' élan vital''" (coined by vitalist Henri Bergson), "vital force", or "''vis vitalis''", which some equate with the soul. In the 18th and 19th centuries, vitalism was discussed among biologists, between those who felt that the known mechanics of physics would eventually explain the difference between life and non-life and vitalists who argued that the processes of life could not be reduced to a mechanistic process. Vitalist biologists such as Johannes Reinke proposed testable hypotheses meant to show inadequacies with mechanistic explanations, but their experiments failed to provide support for vitalism. Biologists now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peripheral Blood Mononuclear Cell
A peripheral blood mononuclear cell (PBMC) is any peripheral blood cell having a round Cell nucleus, nucleus. These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and granulocytes (neutrophils, basophils, and eosinophils) have multi-lobed nuclei. In humans, lymphocytes make up the majority of the PBMC population, followed by monocytes, and only a small percentage of dendritic cells. These cells can be extracted from whole blood using ficoll, a hydrophilic polysaccharide that separates layers of blood, and gradient centrifugation, which will separate the blood into a top layer of plasma, followed by a layer of PBMCs (buffy coat) and a bottom fraction of polymorphonuclear cells (such as neutrophils and eosinophils) and erythrocytes. The polymorphonuclear cells can be further isolated by lysing the red blood cells. Basophils are sometimes found in both the denser and the PBMC fractions. Clinical significan ...

DNA Damage (naturally Occurring)
Natural DNA damage is an alteration in the chemical structure of DNA, such as a break in a strand of DNA, a nucleobase missing from the backbone of DNA, or a chemically changed base such as 8-OHdG. DNA damage can occur naturally or via environmental factors, but is distinctly different from mutation, although both are types of error in DNA. DNA damage is an abnormal chemical structure in DNA, while a mutation is a change in the sequence of base pairs. DNA damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. The DNA damage response (DDR) is a complex signal transduction pathway which recognizes when DNA is damaged and initiates the cellular response to the damage. DNA damage and mutation have different biological consequences. While most DNA damages can undergo DNA repair, such repair is not 100% efficient. Un-repaired DNA damages accumulate in non-replicating cells, such as cells in the brai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
