Potency (other)

	Potency (other) Potency may refer to: * Potency (pharmacology), a measure of the activity of a drug in a biological system * Virility * Cell potency, a measure of the differentiation potential of stem cells * In homeopathic dilutions, potency is a measure of how ''dilute'' a substance is * Potency in philosophy is a specific potentiality in Aristotle's Theory of Potentiality and actuality, or "Act and Potency"; e.g., since the material, stone, is potentially a statue, it has a potency for statuehood, of which the form of any statue is the "act" See also Potent (other) Potens (other) Potens, a Latin word meaning powerful, confer potency, found in the word potentate, may refer to: * '' Metriorhynchus potens'', an extinct Late Jurassic metriorhynchid crocodile species * ''Myolepta potens'', a hoverfly species * '' Psalodon pote ... {{disambig ...

picture info	Potency (pharmacology) In the field of pharmacology, potency is a measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. A highly potent drug (e.g., fentanyl, alprazolam, risperidone, bumetanide, bisoprolol) evokes a given response at low concentrations, while a drug of lower potency (meperidine, diazepam, ziprasidone, furosemide, metoprolol) evokes the same response only at higher concentrations. Higher potency does not necessarily mean greater effectiveness or more side effects.

picture info	Virility Virility (from the Latin ''virilitas'', manhood or virility, derived from Latin ''vir'', man) refers to any of a wide range of masculine characteristics viewed positively. Virile means "marked by strength or force". Virility is commonly associated with vigour, health, sturdiness, and constitution, especially in the fathering of children. In this last sense, virility is to men as fertility is to women. ''Virile'' has become obsolete in referring to a "nubile" young woman, or "a maid that is Marriageable or ripe for a Husband, or Virill". Historically, masculine attributes such as beard growth have been seen as signs of virility and leadership (for example in ancient Egypt and Greece). Male virility Evidence shows that increased male age is associated with a decline in semen volume, sperm motility, and sperm morphology. In studies that controlled for female age, comparisons between men under 30 and men over 50 found relative decreases in pregnancy rates between 23% and 38%. ...

picture info	Cell Potency Pluripotency: These are the cells that can generate into any of the three Germ layers which imply Endodermal, Mesodermal, and Ectodermal cells except tissues like the placenta. According to Latin terms, Pluripotentia means the ability for many things. We can generate Induced Pluripotent cells by using the Induced pluripotency technique by triggering or expressing the genes or the transcription factors of the normal somatic cells. They are abbreviated as iPSC or IPS. We can forcefully express the transcription factors like Oct4, Sox2, Klf4, and c-Myc of a non-pluripotent cell and convert them into a stem cell. This procedure is first studied in a Mouse fibroblast cell in 2006 and followed the same instructions in developing a Human pluripotent cell from a Human epidermal fibroblast cell. The technique is called Regeneration. Though the iPSC has similar properties to embryonic stem cells they were never approved for clinical stage research because they are highly Tumerogenic, hav ...

picture info	Homeopathic Dilutions In homeopathy, homeopathic dilution (known by practitioners as "dynamisation" or "potentisation") is a process in which a substance is :wikt:dilute, diluted with alcohol or distilled water and then vigorously shaken in a process called "succussion". Insoluble solids, such as quartz and oyster shell, are diluted by grinding them with lactose (''trituration''). The founder of homeopathy, Samuel Hahnemann (1755–1843), asserted that the process of succussion activated the "vital energy" of the diluted substance, and that successive dilutions increased the "potency" of the preparation, although other strands of homeopathy (such as Wilhelm Heinrich Schüßler, Schuessler's) disagreed. The concept is pseudoscience because, at commonly used dilutions, no molecules of the original material are likely to remain. Therefore high homeopathic dilutions must be distinguished from low dilutions where there can be an overlap with herbal medicine. Background The founder of homeopathy, Samuel Ha ...

picture info	Potentiality And Actuality In philosophy, potentiality and actuality are a pair of closely connected principles which Aristotle used to analyze motion, causality, ethics, and physiology in his ''Physics'', ''Metaphysics'', ''Nicomachean Ethics'', and ''De Anima''. The concept of potentiality, in this context, generally refers to any "possibility" that a thing can be said to have. Aristotle did not consider all possibilities the same, and emphasized the importance of those that become real of their own accord when conditions are right and nothing stops them. Actuality, in contrast to potentiality, is the motion, change or activity that represents an exercise or fulfillment of a possibility, when a possibility becomes real in the fullest sense. These concepts, in modified forms, remained very important into the Middle Ages, influencing the development of medieval theology in several ways. In modern times the dichotomy has gradually lost importance, as understandings of nature and deity have changed. Howev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
