Spontaneous Coronary Artery Dissection
Spontaneous coronary artery dissection (SCAD) is an uncommon but potentially lethal condition in which one of the arteries that supply the heart spontaneously develops a blood collection, or hematoma, within the artery wall. This leads to a separation. SCAD is member of the vascular dissection (medical) disease family. SCAD is a major cause of heart attacks in young, otherwise healthy women who usually lacking typical cardiovascular risk factors. While the exact cause is not yet known, SCAD is likely related to changes that occur during and after pregnancy, as well as other diseases. These changes lead to the dissection of the wall which restricts blood flow to the heart and causes symptoms. SCAD is often diagnosed in the cath lab with angiography, though more advanced confirmatory tests exist. While the risk of death due to SCAD is low, it has a relatively high rate of recurrence leading to further heart attack-like symptoms in the future. It was first described in 1931. Signs ...

Coronary Artery Disease
Coronary artery disease (CAD), also called coronary heart disease (CHD), ischemic heart disease (IHD), myocardial ischemia, or simply heart disease, involves the reduction of blood flow to the heart muscle due to build-up of atherosclerotic plaque An atheroma, or atheromatous plaque, is an abnormal and reversible accumulation of material in the inner layer of an arterial wall. The material consists of mostly macrophage cells, or debris, containing lipids, calcium and a variable amount ... in the arteries of the heart. It is the most common of the cardiovascular diseases. Types include stable angina, unstable angina, myocardial infarction, and sudden cardiac death. A common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Occasionally it may feel like heartburn. Usually symptoms occur with exercise or emotional Stress (psychological), stress, last less than a few minutes, and improve with rest. Shortness of breath may also o ...

Segmental Colitis Associated With Diverticulosis
Segmental colitis associated with diverticulosis (SCAD) is a condition characterized by localized inflammation in the colon, which spares the rectum and is associated with multiple sac-like protrusions or pouches in the wall of the colon (diverticulosis). Unlike diverticulitis, SCAD involves inflammation of the colon between diverticula (interdiverticular mucosa), while sparing the diverticular orifices. SCAD may lead to abdominal pain, especially in the left lower quadrant, intermittent rectal bleeding and chronic diarrhea. The cause of SCAD is unknown, but may be related to local colonic ischemia, fecal stasis, or mucosal prolapse. The factors that cause SCAD likely overlap with inflammatory bowel disease. There are four types of SCAD, which are categorized based on the appearance during colonoscopy. Pattern A is characterized by involvement of crescentic folds and is the most common type of SCAD (52%). Pattern B has an appearance similar to mild-to moderate ulcerative colitis ...

Colitis
Colitis is swelling or inflammation of the large intestine ( colon). Colitis may be acute and self-limited or long-term. It broadly fits into the category of digestive diseases. In a medical context, the label ''colitis'' (without qualification) is used if: * The cause of the inflammation in the colon is undetermined; for example, ''colitis'' may be applied to ''Crohn's disease'' at a time when the diagnosis is unknown, or * The context is clear; for example, an individual with ulcerative colitis is talking about their disease with a physician who knows the diagnosis. Signs and symptoms The signs and symptoms of colitis are quite variable and dependent on the cause of the given colitis and factors that modify its course and severity. Common symptoms of colitis may include: mild to severe abdominal pains and tenderness (depending on the stage of the disease), persistent hemorrhagic diarrhea with pus either present or absent in the stools, fecal incontinence, flatulence, fatigu ...

Carangidae
The Carangidae are a family of ray-finned fish which includes the jacks, pompanos, jack mackerels, runners, and scads. It is the largest of the six families included within the order Carangiformes. Some authorities classify it as the only family within that order but molecular and anatomical studies indicate that there is a close relationship between this family and the five former Perciform families which make up the Carangiformes. They are marine fishes found in the Atlantic, Indian and Pacific Oceans. Most species are fast-swimming predatory fishes that hunt in the waters above reefs and in the open sea; some dig in the sea floor for invertebrates. The largest fish in the family, the greater amberjack, ''Seriola dumerili'', grows up to 2 m in length; most fish in the family reach a maximum length of 25–100 cm. The family contains many important commercial and game fish, notably the Pacific jack mackerel, ''Trachurus symmetricus'', and the other jack mackerels in ...

Alepes
''Alepes'' is a genus containing five extant species of tropical marine fishes in the jack family, Carangidae. They are commonly known as scads, a term applied to many genera of carangid fishes. Their body form, however, differs from these other scads by being much more ovate in shape, more similar to the larger jacks taken as game fish, although scads are generally much smaller. They are found in coastal waters throughout the Indo-West Pacific region. Taxonomy and phylogeny ''Alepes'' is a genus containing five extant and one extinct species. It is part of the jack family, the Carangidae are part of the order Carangiformes. Recent phylogenetic studies using molecular information have placed ''Alepes'' in the subfamily Caranginae (or the tribe Carangini). The most comprehensive study suggests the genus is basal to all other 'scads' and 'horse mackerels' of the genera ''Trachurus, Decapterus, and Selar'', whilst still being closely affiliated with larger members of Caranginae such ...

Herring Scad
The herring scad (''Alepes vari'') (also known as the duskyfin crevalle and trevally scad), is a common species of tropical marine fish in the jack family Carangidae. The species inhabits the surface waters of coastal regions throughout the Indo-West Pacific region, feeding on a variety of crustaceans and small fishes. It is the largest fish of the scad genus ''Alepes'', growing to a recorded length of 56 cm. The herring scad is identified among the genus ''Alepes'' by its more numerous and smaller scutes and the number of gill rakers on the first arch. It is of minor importance to fisheries throughout its range. Taxonomy and naming The herring scad is one of five extant species in the scad genus ''Alepes'', a group of fish in the jack family, Carangidae. The Carangidae are part of the order Carangiformes. The species was first scientifically described by the French naturalist Georges Cuvier in 1833 from a specimen now lost to science. He named the species ''Caranx vari'', ...

Razorbelly Scad
The razorbelly scad (''Alepes kleinii'') (also known as the banded scad, golden scad and goggle-eye scad) is a small species of tropical marine fish in the jack family, Carangidae. The species inhabits coastal waters in the Indo-Pacific, from Pakistan in the west to Japan and Australia in the east, often found over reefs. The razorbelly scad has a complex taxonomic history, and even recently has had its position in the genus ''Alepes'' challenged, but appears to be stable after a molecular phylogeny study supported its placement in ''Alepes''. It is very similar to other scads in the same genus, but is readily identified by its unique teeth. Razorbelly scad are predatory fish, taking a variety of crustaceans and shrimps, and show a change in feeding intensity over the year. Reproduction and development has been extensively studied in India, where spawning occurs in a single event from January to September. The species is commonly taken in tropical fisheries, where it is marketed f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smallmouth Scad
The smallmouth scad (''Alepes apercna'') (also known as the banded scad and roundfin trevally), is a species of tropical marine fish in the jack family Carangidae. The species is endemic to northern Australia, inhabiting primarily inshore waters. It is similar to other scads in the genus ''Alepes'', and is distinguished by a well-developed posterior adipose eyelid, as well as fin membrane spotting and gill raker counts. It is not a large species, with the maximum length reported to be 29.5 cm. It feeds primarily on a variety of small invertebrates, and is of very minor economic importance. Taxonomy and naming The smallmouth scad is one of five members in the scad genus ''Alepes'', which is one of 33 genera of the jack family, Carangidae. The Carangidae are part of the order Carangiformes. The smallmouth scad has a slightly confusing taxonomic history, with confusion over the classification, the author, and confusion with other species clouding the species past. The first s ...

Decapterus
''Decapterus'' is a genus of marine fishes of jack family, Carangidae, commonly known as mackerel scads, round scads, or horse mackerel. They are found throughout the world. Species Currently, 10 or 12 recognized species are found in this genus: * ''Decapterus akaadsi'' ( T. Abe), 1958 * '' Decapterus koheru'' (Hector, 1875) (koheru) * ''Decapterus kurroides'' (Bleeker, 1855) (redtail scad) * ''Decapterus macarellus'' (G.

OpenSCAD
OpenSCAD is a free software application for creating solid 3D computer-aided design (CAD) objects. It is a script-only based modeller that uses its own description language; parts can be previewed, but cannot be interactively modified by mouse in the 3D view. An OpenSCAD script specifies geometric primitives (such as spheres, boxes, cylinders, etc.) and defines how they are modified and combined (for instance by intersection, difference, envelope combination and Minkowski sums) to render a 3D model. As such, the program does constructive solid geometry (CSG). OpenSCAD is available for Windows, Linux and macOS. Previewing For fast previewing of models using z-buffering, OpenSCAD employs OpenCSG and OpenGL. The 3D model position can be interactively manipulated in the view with a mouse similarly to other 3D modellers. It is also possible to define a default "camera" position in the script. Part colors can be defined in the 3D view (including transparency). Preview is relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
