Pain In Animals
Pain negatively affects the health and welfare of animals. "Pain" is defined by the International Association for the Study of Pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage." Only the animal experiencing the pain can know the pain's quality and intensity, and the degree of suffering. It is harder, if even possible, for an observer to know whether an emotional experience has occurred, especially if the sufferer cannot communicate. Therefore, this concept is often excluded in definitions of pain in animals, such as that provided by Zimmerman: "an aversive sensory experience caused by actual or potential injury that elicits protective motor and vegetative reactions, results in learned avoidance and may modify species-specific behaviour, including social behaviour." Nonhuman animals cannot report their feelings to language-using humans in the same manner as human communication, but obs ...

Physiology
Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. ''Physiological state'' is the condition of normal function. In contrast, ''pathological state'' refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine. Foundations Cells Although there are differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consciousness
Consciousness, at its simplest, is sentience and awareness of internal and external existence. However, the lack of definitions has led to millennia of analyses, explanations and debates by philosophers, theologians, linguisticians, and scientists. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the mind, and at other times, an aspect of mind. In the past, it was one's "inner life", the world of introspection, of private thought, imagination and volition. Today, it often includes any kind of cognition, experience, feeling or perception. It may be awareness, awareness of awareness, or self-awareness either continuously changing or not. The disparate range of research, notions and speculations raises a curiosity about whether the right questions are being asked. Examples of the range of descriptions, definitions or explanations are: simple wakefulness, one's sense of selfhood or sou ...

René Descartes
René Descartes ( or ; ; Latinized: Renatus Cartesius; 31 March 1596 – 11 February 1650) was a French philosopher, scientist, and mathematician, widely considered a seminal figure in the emergence of modern philosophy and science. Mathematics was central to his method of inquiry, and he connected the previously separate fields of geometry and algebra into analytic geometry. Descartes spent much of his working life in the Dutch Republic, initially serving the Dutch States Army, later becoming a central intellectual of the Dutch Golden Age. Although he served a Protestant state and was later counted as a deist by critics, Descartes considered himself a devout Catholic. Many elements of Descartes' philosophy have precedents in late Aristotelianism, the revived Stoicism of the 16th century, or in earlier philosophers like Augustine. In his natural philosophy, he differed from the schools on two major points: first, he rejected the splitting of corporeal substance into mat ...

Human Being
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedality, bipedalism and exceptional cognitive skills due to a large and complex Human brain, brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from family, families and kinship networks to political state (polity), states. Social interactions between humans have established a wide variety of values, norm (sociology), social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate Phenomenon, phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthropomorphism
Anthropomorphism is the attribution of human traits, emotions, or intentions to non-human entities. It is considered to be an innate tendency of human psychology. Personification is the related attribution of human form and characteristics to abstract concepts such as nations, emotions, and natural forces, such as seasons and weather. Both have ancient roots as storytelling and artistic devices, and most cultures have traditional fables with anthropomorphized animals as characters. People have also routinely attributed human emotions and behavioral traits to wild as well as domesticated animals. Etymology Anthropomorphism and anthropomorphization derive from the verb form ''anthropomorphize'', itself derived from the Greek ''ánthrōpos'' (, "human") and ''morphē'' (, "form"). It is first attested in 1753, originally in reference to the heresy of applying a human form to the Christian God.''Oxford English Dictionary'', 1st ed. "anthropomorphism, ''n.''"

Carprofen
Carprofen is a non-steroidal anti-inflammatory drug (NSAID) of the propionic acid class that was previously for use in humans and animals, but is now only available to veterinarians for prescribing as a supportive treatment for various conditions in only animals. Carprofen reduces inflammation by inhibition of COX-1 and COX-2; its specificity for COX-2 varies from species to species. Marketed under many brand names worldwide, carprofen provides day-to-day treatment for pain and inflammation from various kinds of joint pain, as well as post-operative pain. Human use Carprofen was used in humans for almost ten years, starting in 1988. It was used for the same conditions as in dogs, namely joint pain and inflammation. Side effects tended to be mild, usually consisting of nausea or gastrointestinal pain and diarrhoea. It was available only by prescription in 150 mg to 600 mg doses. Dosage over 250 mg was only for relieving pain after severe trauma, such as post-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argument
An argument is a statement or group of statements called premises intended to determine the degree of truth or acceptability of another statement called conclusion. Arguments can be studied from three main perspectives: the logical, the dialectical and the rhetorical perspective. In logic, an argument is usually expressed not in natural language but in a symbolic formal language, and it can be defined as any group of propositions of which one is claimed to follow from the others through deductively valid inferences that preserve truth from the premises to the conclusion. This logical perspective on argument is relevant for scientific fields such as mathematics and computer science. Logic is the study of the forms of reasoning in arguments and the development of standards and criteria to evaluate arguments. Deductive arguments can be valid, and the valid ones can be sound: in a valid argument, premisses necessitate the conclusion, even if one or more of the premises is false ...

Black Sea Bass
The black sea bass (''Centropristis striata'') is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae which is part of the family Serranidae, which also includes the groupers and anthias. It is found in the western Atlantic Ocean, where it is an important species for commercial and recreational fisheries. Description The black sea bass has an oblong, laterally compressed body. It has a large mouth, armed with bands of teeth on the jaw and with a triangular patch of teeth in the front part roof of the mouth and more teeth along the sides of that area, the mouth extending as far as below the middle of the eye. The preopercle has fine serrations on its margin and is evenly rounded, while the gill cover bears three flat spines. The dorsal fin has ten spines, the front spines being longer than the rearmost, and 11 soft rays. The membranes between the spines of the dorsal fin are deeply notched. The anal fin has three spines and seven soft rays. The caudal fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longfin Inshore Squid
The longfin inshore squid (''Doryteuthis pealeii'') is a species of squid of the family Loliginidae. Description This species of squid is often seen with a reddish hue, but like many types of squid can manipulate its color, varying from a deep red to a soft pink. The dorsal mantle length of some males can reach up to 50 cm, although most squid commercially harvested are smaller than 30 cm long. This species exhibits sexual dimorphism, with most males growing faster and reaching larger sizes than females. Distribution The longfin inshore squid is found in the North Atlantic, schooling in continental shelf and slope waters from Newfoundland to the Gulf of Venezuela. It is commercially exploited, especially in the range from the Southern Georges Bank to Cape Hatteras. The population makes seasonal migrations that appear to be related to bottom water temperatures; they move offshore during late autumn to overwinter along the edge of the continental shelf and return ...

Maladaptive
In evolution, a maladaptation () is a trait that is (or has become) more harmful than helpful, in contrast with an adaptation, which is more helpful than harmful. All organisms, from bacteria to humans, display maladaptive and adaptive traits. In animals (including humans), adaptive behaviors contrast with maladaptive ones. Like adaptation, maladaptation may be viewed as occurring over geological time, or within the lifetime of one individual or a group. It can also signify an adaptation that, whilst reasonable at the time, has become less and less suitable and more of a problem or hindrance in its own right, as time goes on. This is because it is possible for an adaptation to be poorly selected or become more of a dysfunction than a positive adaptation, over time. Note that the concept of maladaptation, as initially discussed in a late 19th-century context, is based on a flawed view of evolutionary theory. It was believed that an inherent tendency for an organism's adaptations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allodynia
Allodynia is a condition in which pain is caused by a stimulus that does not normally elicit pain. For example, bad sunburn can cause temporary allodynia, and touching sunburned skin, or running cold or warm water over it, can be very painful. It is different from hyperalgesia, an exaggerated response from a normally painful stimulus. The term is from Ancient Greek '' άλλος'' ''állos'' "other" and '' οδύνη'' ''odúnē'' "pain". Types There are different kinds or types of allodynia: * Mechanical allodynia (also known as tactile allodynia) ** Static mechanical allodynia – pain in response when touched ** Dynamic mechanical allodynia – pain in response to stroking lightly * Thermal (hot or cold) allodynia – pain from normally mild skin temperatures in the affected area * Movement allodynia – pain triggered by normal movement of joints or muscles Causes Allodynia is a clinical feature of many painful conditions, such as neuropathies,Landerholm, A.
