Pharmacologic Actions
Pharmacology is a branch of medicine, biology and pharmaceutical sciences concerned with drug or medication action, where a drug may be defined as any artificial, natural, or endogenous (from within the body) molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism (sometimes the word ''pharmacon'' is used as a term to encompass these endogenous and exogenous bioactive species). More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties,functions,sources,synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilit ...

Absorption (pharmacology)
Absorption is the journey of a drug travelling from the site of administration to the site of action. The drug travels by some route of administration (oral, topical-dermal, etc.) in a chosen dosage form (e.g., tablets, capsules, or in solution). Absorption by some other routes, such as intravenous therapy, intramuscular injection, enteral nutrition, is even more straightforward and there is less variability in absorption and bioavailability is often near 100%. Intravascular administration does not involve absorption, and there is no loss of drug. The fastest route of absorption is inhalation. Absorption is a primary focus in drug development and medicinal chemistry, since a drug must be absorbed before any medicinal effects can take place. Moreover, the drug's pharmacokinetic profile can be easily and significantly changed by adjusting factors that affect absorption. Dissolution In the most common situation, a tablet is ingested and passes through the esophagus to the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek Religion
Religious practices in ancient Greece encompassed a collection of beliefs, rituals, and mythology, in the form of both popular public religion and cult practices. The application of the modern concept of "religion" to ancient cultures has been questioned as anachronistic. The ancient Greeks did not have a word for 'religion' in the modern sense. Likewise, no Greek writer known to us classifies either the gods or the cult practices into separate 'religions'. Instead, for example, Herodotus speaks of the Hellenes as having "common shrines of the gods and sacrifices, and the same kinds of customs." Most ancient Greeks recognized the twelve major Olympian gods and goddesses—Zeus, Hera, Poseidon, Demeter, Athena, Ares, Aphrodite, Apollo, Artemis, Hephaestus, Hermes, and either Hestia or Dionysus—although philosophies such as Stoicism and some forms of Platonism used language that seems to assume a single transcendent deity. The worship of these deities, and several others, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scapegoat
In the Bible, a scapegoat is one of a pair of kid goats that is released into the wilderness, taking with it all sins and impurities, while the other is sacrificed. The concept first appears in the Book of Leviticus, in which a goat is designated to be cast into the desert to carry away the sins of the community. Practices with some similarities to the scapegoat ritual also appear in Ancient Greece and Ebla. Origins Some scholars have argued that the scapegoat ritual can be traced back to Ebla around 2400 BC, from where it spread throughout the ancient Near East. Etymology The word "scapegoat" is an English translation of the Hebrew ( he, עזאזל), which occurs in Leviticus 16:8: The Brown–Driver–Briggs Hebrew Lexicon gives () as a reduplicative intensive of the stem , "remove", hence , "for entire removal". This reading is supported by the Greek Old Testament translation as "the sender away (of sins)". The lexicographer Gesenius takes to mean "averter", wh ...

Pharmakos
A pharmakós ( el, φαρμακός, plural ''pharmakoi'') in Ancient Greek religion was the ritualistic sacrifice or exile of a human scapegoat or victim. Ritual A slave, a cripple, or a criminal was chosen and expelled from the community at times of disaster (famine, invasion or plague) or at times of calendrical crisis. It was believed that this would bring about purification. On the first day of the Thargelia, a festival of Apollo at Athens, two men, the ''pharmakoi'', were led out as if to be sacrificed as an expiation. Some scholia state that ''pharmakoi'' were actually sacrificed (thrown from a cliff or burned), but many modern scholars reject this, arguing that the earliest source for the ''pharmakos'' (the iambic satirist Hipponax) shows the ''pharmakoi'' being beaten and stoned, but not executed. A more plausible explanation would be that sometimes they were executed and sometimes not, depending on the attitude of the victim. For instance, a deliberate unrepentant murde ...

Pharmacy
Pharmacy is the science and practice of discovering, producing, preparing, dispensing, reviewing and monitoring medications, aiming to ensure the safe, effective, and affordable use of medicines. It is a miscellaneous science as it links health sciences with pharmaceutical sciences and natural sciences. The professional practice is becoming more clinically oriented as most of the drugs are now manufactured by pharmaceutical industries. Based on the setting, pharmacy practice is either classified as community or institutional pharmacy. Providing direct patient care in the community of institutional pharmacies is considered clinical pharmacy. The scope of pharmacy practice includes more traditional roles such as compounding and dispensing of medications. It also includes more modern services related to health care including clinical services, reviewing medications for safety and efficacy, and providing drug information. Pharmacists, therefore, are experts on drug therapy and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
-logia
''-logy'' is a suffix in the English language, used with words originally adapted from Ancient Greek ending in ('). The earliest English examples were anglicizations of the French '' -logie'', which was in turn inherited from the Latin '' -logia''. The suffix became productive in English from the 18th century, allowing the formation of new terms with no Latin or Greek precedent. The English suffix has two separate main senses, reflecting two sources of the suffix in Greek: *a combining form used in the names of school or bodies of knowledge, e.g., ''theology'' (loaned from Latin in the 14th century) or ''sociology''. In words of the type ''theology'', the suffix is derived originally from (''-log-'') (a variant of , ''-leg-''), from the Greek verb (''legein'', 'to speak')."-logy." ''The Concise Oxford Dictionary of English Etymology''. Oxford University Press, 1986. retrieved 20 August 2008.

Poison
Poison is a chemical substance that has a detrimental effect to life. The term is used in a wide range of scientific fields and industries, where it is often specifically defined. It may also be applied colloquially or figuratively, with a broad sense. Whether something is considered a poison may change depending on the amount, the circumstances, and what living things are present. Poisoning could be accidental or deliberate, and if the cause can be identified there may be ways to neutralise the effects or minimise the symptoms. In biology, a poison is a chemical substance causing death, injury or harm to organisms or their parts. In medicine, poisons are a kind of toxin that are delivered passively, not actively. In industry the term may be negative, something to be removed to make a thing safe, or positive, an agent to limit unwanted pests. In ecological terms, poisons introduced into the environment can later cause unwanted effects elsewhere, or in other parts of the food ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biomedical Sciences
Biomedical sciences are a set of sciences applying portions of natural science or formal science, or both, to develop knowledge, interventions, or technology that are of use in healthcare or public health. Such disciplines as medical microbiology, clinical virology, clinical epidemiology, genetic epidemiology, and biomedical engineering are medical sciences. In explaining physiological mechanisms operating in pathological processes, however, pathophysiology can be regarded as basic science. Biomedical Sciences, as defined by the UK Quality Assurance Agency for Higher Education Benchmark Statement in 2015, includes those science disciplines whose primary focus is the biology of human health and disease and ranges from the generic study of biomedical sciences and human biology to more specialised subject areas such as pharmacology, human physiology and human nutrition. It is underpinned by relevant basic sciences including anatomy and physiology, cell biology, biochemistry, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
