Snatiation
Snatiation is a term coined to refer to the medical condition originally termed "stomach sneeze reflex", which is characterized by uncontrollable bursts of sneezing brought on by fullness of the stomach, typically immediately after a large meal. The type of food consumed does not appear to affect its occurrence. It is reported, based on a preliminary study, to be passed along genetically as an autosomal dominant trait, as first described by Ahmad Teebi and Qasem Al-Saleh in 1989. The term "snatiation", coined shortly thereafter in a humorous letter to the ''Journal of Medical Genetics'' by Judith G. Hall, is a portmanteau of the words ''sneeze'' and ''satiation''. Hall also provides the humorous backronym, Sneezing Non-controllably At a Time of Indulgence of the Appetite—a Trait Inherited and Ordained to be Named. Similar in nature to this condition is gustatory rhinitis, which involves rhinorrhea induced by certain foods, such as spicy foods. See also * Photic sneeze reflex ...

Sneeze
A sneeze (also known as sternutation) is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa. A sneeze expels air forcibly from the mouth and nose in an explosive, spasmodic involuntary action. This action allows for mucus to escape through the nasal cavity. Sneezing is possibly linked to sudden exposure to bright light, sudden change (fall) in temperature, breeze of cold air, a particularly full stomach, exposure to allergens, or viral infection. Because sneezes can spread disease through infectious aerosol droplets, it is recommended to cover one's mouth and nose with the forearm, the inside of the elbow, a tissue or a handkerchief while sneezing. In addition to covering the mouth, looking down is also recommended in order to change the direction of the droplets spread and avoid high concentration in the human breathing heights. The function of sneezing is to expel mucus con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photic Sneeze Reflex
The photic sneeze reflex (also known as Autosomal Dominant Compelling Helio-Ophthalmic Outburst (ACHOO) syndrome or photoptarmosis, of the combining form from Ancient Greek φῶς, ''phōs'', "light" and πταρμός, ''ptarmós'', "sneeze", colloquially sun sneezing or photosneezia) is an inherited and congenital autosomal dominant reflex condition that causes sneezing in response to numerous stimuli, such as looking at bright lights or periocular (surrounding the eyeball) injection. The condition affects 18–35% of the world's population, but its exact mechanism of action is not well understood. Symptoms and signs The photic sneeze reflex manifests itself in the form of uncontrollable sneezing in response to a stimulus which would not produce a sneeze in people without the trait. The sneezes generally occur in bursts of 1 to 10 sneezes, followed by a refractory period that can be as long as 24 hours. Photic sneezing A photic sneeze results from exposure to a bright light ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...

Autosomal Dominant
In genetics, dominance is the phenomenon of one variant (allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second recessive. This state of having two different variants of the same gene on each chromosome is originally caused by a mutation in one of the genes, either new (''de novo'') or inherited. The terms autosomal dominant or autosomal recessive are used to describe gene variants on non-sex chromosomes ( autosomes) and their associated traits, while those on sex chromosomes (allosomes) are termed X-linked dominant, X-linked recessive or Y-linked; these have an inheritance and presentation pattern that depends on the sex of both the parent and the child (see Sex linkage). Since there is only one copy of the Y chromosome, Y-linked traits cannot be dominant or recessive. Additionally, there are other forms of dominance such as incomplete d ...

Ahmad Teebi
Ahmad Said Teebi ( ar, أحمد سعيد طيبي, 22 July 1949 – 22 July 2010) was a Palestinian, born in Lebanon, clinical geneticist who studied and practiced in several countries, ending his career in Canada and the United States. Biography Ahmad Teebi was born in Beirut, Lebanon, to a family of Palestinian origin. He received his primary education in Lebanon and in Kuwait. He obtained his medical degree from Cairo University (1973), then studied Pediatrics in Kuwait. He studied at University College of Dublin in 1976–77, receiving a Diploma of Child Health in 1977. He began his medical residency at the Kuwait Medical Genetics Center (1977–1980), then completed it at the University of British Columbia (studying Medical Genetics and Pediatrics in 1986), and in the United States at Yale University (1990-1993). In 1983, Teebi received a DHCG from the London School of Hygiene and Tropical Medicine. In 1992, Teebi was asked to join the Division of Medical Genetics at th ...

Portmanteau
A portmanteau word, or portmanteau (, ) is a blend of wordsGarner's Modern American Usage , p. 644. in which parts of multiple words are combined into a new word, as in ''smog'', coined by blending ''smoke'' and ''fog'', or ''motel'', from ''motor'' and ''hotel''. In , a portmanteau is a single morph that is analyzed as representing two (or more) underlying s. When portmanteaus shorten es ...

Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. An acronym is a word derived from the initial letters of the words of a phrase, such as ''radar'' from "''ra''dio ''d''etection ''a''nd ''r''anging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin." Many fictional espionage organizations are backronyms, such as SPECTRE (''sp''ecial ''e''xecutive for ''c''ounterintelligence, ''t''errorism, ''r''evenge and ''e''xtortion) from the James Bond franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl who was abducted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinorrhea
Rhinorrhea, rhinorrhoea, or informally runny nose is the free discharge of a thin mucus fluid from the nose; it is a common condition. It is a common symptom of allergies ( hay fever) or certain viral infections, such as the common cold or COVID-19. It can be a side effect of crying, exposure to cold temperatures, cocaine abuse, or drug withdrawal, such as from methadone or other opioids. Treatment for rhinorrhea is not usually undertaken, but there are a number of medical treatments and preventive techniques. The term was coined in 1866 from the Ancient Greek, Greek ''rhino-'' ("of the nose") and ''-rhoia'' ("discharge" or "flow"). Signs and symptoms Rhinorrhea is characterized by an excess amount of mucus produced by the mucous membranes that line the nasal cavities. The membranes create mucus faster than it can be processed, causing a backup of mucus in the nasal cavities. As the cavity fills up, it blocks off the air passageway, causing difficulty breathing through the nose. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
