The term "pannus" is derived from the Latin for "tablecloth". Inflammation and exuberant proliferation of the synovium leads to formation of pannus and destruction of cartilage, bone, tendons, ligaments, and blood vessels. Basically, the hypertrophied synovium is called pannus. Pannus tissue is composed of aggressive macrophage- and fibroblast-like mesenchymal cells, macrophage-like cells and other inflammatory cells that release collagenolytic enzymes.

Pannus is an abnormal layer of fibrovascular tissue or granulation tissue. Common sites for pannus formation include over the cornea, over a joint surface (as seen in rheumatoid arthritis), or on a prosthetic heart valve.Farlex Partner Medical Dictionary © Farlex 2012 Pannus may grow in a tumor-like fashion, as in joints where it may erode articular cartilage and bone. In common usage, the term pannus is often used to refer to a panniculus (a hanging flap of tissue).

In ophthalmology, pannus refers to the growth of blood vessels into the peripheral cornea. In normal individuals, the cornea is avascular. Chronic local hypoxia (such as that occurring with overuse of contact lenses) or inflammation may lead to peripheral corneal vascularization, or pannus. Pannus may also develop in diseases of the corneal stem cells, such as aniridia.

|
Pannus clouds may also form when an updraft ingests precipitation-cooled air from the downdraft. Scud forming in this region of the storm, if moving laterally, will tend to move inward towards the dominant updraft. Rising scud may condense and organize into a wall cloud. Pannus clouds can often be mistaken for a developing tornado, landspout, or waterspout.

Mental retardation and slowly progressive cerebellar abnormalities were also diagnosed in patients. Other symptoms include corneal edema, thickening of Descemet membrane, and degenerative pannus. Abnormalities were found in muscle and sural nerves.

The pannus supplementary feature is sometimes seen with precipitating Cumulus mediocris, but in this case the CL7 reporting code normally used with to identify pannus is usually superseded by CL2, since there is significant vertical development. Pileus (cap cloud), velum (apron), arcus (roll or shelf cloud) and tuba (vertical column) features are also occasionally seen with cumulus mediocris. Cumulus mediocris may form as a result of a partial transformation of altocumulus or stratocumulus. This genus and species type may also be the result of a complete transformation of stratocumulus or stratus.

Low cloud weather map symbols: Includes low-étage and upward-growing vertical. Cumulus clouds come in four distinct species, cumulis humilis, mediocris, congestus, and fractus. These species may be arranged into the variety, cumulus radiatus; and may be accompanied by up to seven supplementary features, cumulus pileus, velum, virga, praecipitatio, arcus, pannus, and tuba. The species Cumulus fractus is ragged in appearance and can form in clear air as a precursor to cumulus humilis and larger cumulus species-types; or it can form in precipitation as the supplementary feature pannus (also called scud) which can also include stratus fractus of bad weather.

NOAA Cloud Types - NOAA Chart of Different Cloud Types. Observing fractus gives an indication of wind movements under the parent cloud. Masses of multiple fractus clouds, located under a main cloud, are called pannus. Fractonimbus are a form of stratus fractus, developing under precipitation clouds due to turbulent air movement.

Stratus cumulogenitus clouds occur when the base of cumulus clouds spreads, creating a nebulous sheet of stratiform clouds. This can also occur on nimbostratus clouds (stratus nimbostratogenitus) and on cumulonimbus clouds (stratus cumulonimbogenitus). Stratus fractus clouds can also form under the base of precipitation-bearing clouds and are classified as pannus clouds.

Chronic superficial keratitis in a dog Chronic superficial keratitis (CSK), also known as pannus or Uberreiter's disease, is an inflammatory condition of the cornea in dogs, particularly seen in the German Shepherd. Both eyes are usually affected. The corneas gradually become pigmented and infiltrated by blood vessels, and the dog may eventually become blind.

They mostly appear under the precipitation of major rain-bearing clouds; these are the nimbostratus clouds, and the cumulonimbus clouds, and are classified as pannus clouds. Stratus fractus can also form beside mountain slopes, without the presence of nimbus clouds (clouds that precipitate), and their color can be from dark grey to almost white.

The work is also known for its discussion of the principle of decorum (the use of appropriate vocabulary and diction in each style of writing) (l.81–106), and for Horace's criticisms of purple prose (purpureus pannus, l.15–16), a term coined by him to mean the use of flowery language.The Norton Anthology of Theory and Criticism, p. 123.

An accessory cloud recently officially recognized the World meteorological Organization is the flumen, also known more informally as the beaver's tail. It is formed by the warm, humid inflow of a super-cell thunderstorm, and can be mistaken for a tornado. Although the flumen can indicate a tornado risk, it is similar in appearance to pannus or scud clouds and does not rotate.

The Dutch Breed Club initiated a hotline in 2008 for reporting health and behavioral problems. Most genetic health problems occur at a low rate in this breed. Confirmed genetic diseases diagnosed in Dutch Shepherds include allergies (atopy), masticatory myositis, pannus, cryptorchidism and inflammatory bowel disease. Within the rough-haired variety care should be taken to screen for goniodysplasia before breeding.

The disease progresses by forming granulation tissue at the edges of the synovial lining, pannus with extensive angiogenesis and enzymes causing tissue damage. The fibroblast-like synoviocytes have a prominent role in these pathogenic processes. The synovium thickens, cartilage and underlying bone disintegrate, and the joint deteriorates, with raised calprotectin levels serving as a biomarker of these events. Cytokines and chemokines attract and accumulate immune cells, i.e.

Once the corneal surface has stabilized, surgery is the main approach to treatment. Types of surgeries: #In the case of a partial LSCD:, a sequential sector conjunctival epitheliectomy (SSCE) can be performed to remove any tissue (pannus) that has grown over the cornea. This procedure is sometimes used as a temporary measure until further surgical interventions are possible. #Transplantation of amniotic membrane from a placenta may also help.

Pannus clouds are formed as the warmer (and often more moist) updraft of a thunderstorm lifts the relatively warm air near the surface. These clouds condense as the warm, moist air saturates through ascent and is pushed outward from the storm. Scud clouds are very commonly found on the leading edge of a storm front. In this area of a storm, scud are commonly associated with shelf clouds.

Cumulus congestus pileus clouds Cumulus supplementary features are most commonly seen with the species congestus. Cumulus virga clouds are cumulus clouds producing virga (precipitation that evaporates while aloft), and cumulus praecipitatio produce precipitation that reaches the Earth's surface. Cumulus pannus comprise shredded clouds that normally appear beneath the parent cumulus cloud during precipitation. Cumulus arcus clouds have a gust front, and cumulus tuba clouds have funnel clouds or tornadoes.

The specialized instruments used in their operations ran into scores. Innovations such as the “injection syringe”, a hollow needle, invented by Ammar ibn Ali of Mosul, which was used for the extraction by suction of soft cataracts, were quite common. Muslim physicians described such conditions as pannus, glaucoma (described as ‘headache of the pupil’), phlyctenulae, and operations on the conjunctiva. They were the first to use the words 'retina' and 'cataract'.

On 8 April 1534, Cardinal de Gorrevod presided over the ceremony of the transfer of the "Holy Shroud" (pannus Sindon nuncupatus), which had suffered serious damage from fire, from the Sainte Chapelle in the castle of Chambéry, where it was being kept by its owner the Duke of Savoy, to the Convent of the Poor Clares in Chambéry, where repair work was to be done on the cloth. The shroud was later taken to Turin.

The pannus receives blood supply from the newly formed vessels and grows inward, invading the articular cartilage and bone within the joint. The damage to the once healthy tissue causes inflammation and ultimately fluid build-up in the joint. An accumulation of fluid results and the joints swell, slowly decreasing the space that keeps the bones from touching. If this condition is not treated, the joint space will completely narrow, causing ankylosis.

Green says the story is perfect for Manilius; he is able to use it to justify the constellations' proximity to one another and their eternal arrangement, as he had previously argued in 1.354360.Green (2014), p. 46. Conversely, Housman compared it unfavorably to Ovid's version of the story and called Manilius's retelling "a sewn-on patch of far from the best purple" (purpurae non sane splendidissimae adsutus pannus).Manilius & Housman (1930), p. 70.

A hyperplastic synovial lining layer can be caused by the expansion of synovial fibroblast and macrophage cells. This expansion of the synovial membrane, sometimes referred to as "pannus," can lead to bony erosions and cartilage degradation at the site of the cartilage-bone junction in the periarticular bone. It is important to note that the cause of rheumatoid arthritis is unknown. It is speculated that genetic and environmental factors can both contribute to the development of rheumatoid arthritis.

Some of these health disorders include, hypothyroidism, hip dysplasia, osteochondrosis dissecans (OCD), pannus, progressive retinal atrophy (PRA), epilepsy, skin disorders and cancerous lesions in the mouth, on the skin and other areas of the body. As with other breeds, un-spayed female GSPs are prone to breast cancer. This risk is reduced if they are spayed. A genetic form of lupus, termed exfoliative cutaneous lupus erythematosus (ECLE) has also been recognized in German shorthaired pointer dogs.

Pannus, or scud clouds, is a type of fractus cloud at low height above ground, detached, and of irregular form, found beneath nimbostratus or cumulonimbus clouds. These clouds are often ragged or wispy in appearance. When caught in the outflow (downdraft) beneath a thunderstorm, scud clouds will often move faster than the storm clouds themselves. When in an inflow (updraft) area, scud clouds tend to rise and may exhibit lateral movement ranging from very little to substantial.

A purple patch is an over-written passage in which the writer has strained too hard to achieve an impressive effect, by elaborate figures or other means. The phrase (Latin: "purpureus pannus") was first used by the Roman poet Horace in his Ars Poetica (c. 20 BC) to denote an irrelevant and excessively ornate passage; the sense of irrelevance is normally absent in modern usage, although such passages are usually incongruous. By extension, purple prose is lavishly figurative, rhythmic, or otherwise overwrought.

The species fractus shows variable instability because it can be a subdivision of genus-types of different physical forms that have different stability characteristics. This subtype can be in the form of ragged but mostly stable stratiform sheets (stratus fractus) or small ragged cumuliform heaps with somewhat greater instability (cumulus fractus). When clouds of this species are associated with precipitating cloud systems of considerable vertical and sometimes horizontal extent, they are also classified as accessory clouds under the name pannus (see section on supplementary features).

Panniculus, often incorrectly referred to as pannus, is a medical term describing a dense layer of fatty tissue, consisting of excess subcutaneous fat within the lower abdominal region. Panniculi can form after rapid weight loss, as seen with strict exercise plans—in this case, the abdominal fat is successfully reduced, but excess skin is left behind which hangs loosely over the area. It can be a result of obesity and can be mistaken for a tumor or hernia. Abdominal panniculus can be removed during abdominal panniculectomy, a type of abdominoplasty.

A 65 year old patient with rheumatoid arthritis displaying swan neck deformity. Rheumatoid arthritis is an autoimmune disease that is characterized by inflammation of the synovial joints due to attack by the body's own immune system. In this condition, the white blood cells travel through the blood stream to the synovial joints and release pro-inflammatory cytokines upon arrival. The result of this chemical release causes the synovial cells to release harmful chemicals in response as well as begin the growth of new blood vessels, forming a pannus.

This happened, apparently in imitation of the usage outside of Rome, between the tenth and twelfth centuries; however, the exact date cannot be given. But it is certain that as early as the end of the twelfth century the fanon was worn solely by the pope, as is evident from the express statement of Innocent III (1198–1216). The vestment was then called an orale; the name of fanon, from the late Latin fano, derived from pannus (penos), cloth, woven fabric, was not used until a subsequent age. Even as early as the eighth century the pope wore the fanon only at solemn high Mass.

A certain school of linguists tends to believe that it was derived from the fact that, when Pamiers was founded, its new inhabitants were given land parcels measured in pams', from empan (from the Latin "pannus" meaning "piece of cloth"). Originally it was called Ville de Pams. Another explanation is one involving Roger II de Foix, who had gone to a crusade in the region of Apamea in Syria and who, upon his return to France, gave his castle and domain the name of one of his battles: Castrum Appamiae, name later on given to the town. The fact that Pamiers' inhabitants are called Appaméens would seem to favour this hypothesis.

Supplementary cloud formations detached from the main cloud are known as accessory clouds. The heavier precipitating clouds, nimbostratus, towering cumulus (cumulus congestus), and cumulonimbus typically see the formation in precipitation of the pannus feature, low ragged clouds of the genera and species cumulus fractus or stratus fractus. A group of accessory clouds comprise formations that are associated mainly with upward-growing cumuliform and cumulonimbiform clouds of free convection. Pileus is a cap cloud that can form over a cumulonimbus or large cumulus cloud, whereas a velum feature is a thin horizontal sheet that sometimes forms like an apron around the middle or in front of the parent cloud.

Corduroy: This modern diagram shows the warp (3) and the long (red-4) and short (green-5) weft threads; traditionally the knife (1) and the guide (2) are attached and the cutting motion is upwards. Known in Late Latin as fustaneum or fustanum and in Medieval Latin as pannus fustāneus ('fustian cloth') or tela fustānea ('fustian mesh'), the cloth is possibly named after the Egyptian city of Fustat near Cairo that manufactured such a material. It embraces plain twilled cloth known as jean, and cut fabrics similar to velvet, known as velveteen, moleskin, corduroy etc. The original medieval fustian was a stout but respectable cloth with a cotton weft and a linen warp.

A chartered market town, the centre of Kendal has formed round a high street with fortified alleyways, known locally as yards, off to either side, which allowed local people to shelter from the Anglo-Scottish raiders known as Border Reivers. The main industry in those times was the manufacture of woollen goods, whose importance is reflected in the town's coat of arms and in its Latin motto Pannus mihi panis (Cloth is my bread.) "Kendal Green" was a hard-wearing, wool-based fabric specific to the local manufacturing process. It was supposedly sported by the Kendalian archers instrumental in the English victory over the French at the Battle of Agincourt. Kendal Green was also worn by slaves in the Americas and appears in songs and literature from that time.

Several indirect measurements on CT can be used to assess ligamentous integrity at the craniocervical junction. The Wackenheim line, a straight line extending along the posterior margin of the clivus through the dens, should not intersect the dens on plain film, with violation of this relationship raising concern for basilar invagination. The basion to axion interval, or BAI, is also used, which is determined by measuring the distance between an imaginary vertical line at the anterior skull base, or basion, at the foramen magnum, and the axis of the cervical spine along its posterior margin, which should measure 12 mm, an assessment more reliable on radiograph than CT. The distance between the atlas and the occipital condyles, the atlanto-occipital interval (AOI), should measure less than 4 mm, and is better assessed on coronal images. The distances between the dens and surrounding structures are also key features that can suggest the diagnosis, with the normal distance between the dens and basion (BDI) measuring less than 9 mm on CT, and the distance between the dens and atlas (ADI) measuring less than 3 mm on CT, although this can be increased in cases of rheumatoid arthritis due to pannus formation.
