Sari Cancer
Sari cancer is a type of skin cancer that occurs along the waistline in females wearing the sari, caused by constant irritation which can result in scaling and changes in pigmentation of the skin. It is a rare type of cancer and generally found in the Indian subcontinent, where saris are commonly worn by girls and women throughout their lives. It is similar to Marjolin's ulcer in cause, involving chronic inflammation. Signs and symptoms The foremost symptoms of sari cancer are the constant irritation with scaling and pigmentation change at the waistline; gradually these become chronic. The person may have non-healing ulcer or a hyper- or hypopigmented patch or a growth-like lesion over the waistline. The lesion may be associated with serous discharge with foul smell. Cause The sari is common female attire in the Indian subcontinent. It is a piece of long (generally ) cloth which can be made of various materials: cotton, silk, nylon, chiffon or synthetic fabric. It is worn ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dhoti
The dhoti, also known as veshti, vetti, dhuti, mardani, chaadra, dhotar, jaiñboh, panchey, is a type of sarong, tied in a manner that outwardly resembles "loose trousers". It is a lower garment forming part of the ethnic costume for men in the Indian subcontinent. The ''dhoti'' is fashioned out of a rectangular piece of unstitched cloth, usually around long, wrapped around the waist and the legs and knotted, either in the front or the back. The ''dhoti'' is touted as the male counterpart of the ''sari'' worn by females to religious and secular ceremonies ( functions). is a yellow silk dhoti, worn on auspicious occasions. The dhoti which is worn around the lower waist and drawn up in between the legs, is a 5-yard-long piece of woven fabric; it must not be confused with pre- stitched "dhoti pants", which are a new ready to wear trend these days, popular among women and typical of children. Etymology The word ''dhoti'' is derived from ''dhauti'' (Sanskrit: धौती), transl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

Jean-Nicolas Marjolin
Jean-Nicolas Marjolin (6 December 1780 – 4 March 1850) was a French surgeon and pathologist born in Ray-sur-Saône, Haute-Saône. His name is associated with a malady known as Marjolin's ulcer. After a brief stint in the French military, he attached himself to a physician, a friend of the family who allowed Marjolin to attend Commercy Hospital as a student. In 1800 he relocated to Paris with a letter of recommendation from Alexis Boyer (1757–1833). Here he became a favoured disciple of Guillaume Dupuytren (1777–1835). In 1803 he gained his internship, followed by promotions as an anatomy assistant (1805) and prosector (1806). In 1808 he earned his medical doctorate, and two years later opened an amphitheater on Rue des Rats (today- Rue Colbert). Here he taught classes that numbered more than 200 pupils. In 1816 he was appointed second surgeon at the Hôtel-Dieu de Paris with Dupuytren as departmental head. By this time Marjolin's relationship with Dupuytren had soured, event ...

Skin Grafting
Skin grafting, a type of graft surgery, involves the transplantation of skin. The transplanted tissue is called a skin graft. Surgeons may use skin grafting to treat: * extensive wounding or trauma * burns * areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans * specific surgeries that may require skin grafts for healing to occur - most commonly removal of skin cancers Skin grafting often takes place after serious injuries when some of the body's skin is damaged. Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: reducing the course of treatment needed (and time in the hospital), and improving the function and appearance of the area of the body which receives the skin graft. There are two types of skin grafts: * The more common type involves removing a thin layer of skin from a healthy part of the body (the donor section) - like peeling a potato. * A full ...

Malignancy
Malignancy () is the tendency of a medical condition to become progressively worse. Malignancy is most familiar as a characterization of cancer. A ''malignant'' tumor contrasts with a non-cancerous ''benign'' tumor in that a malignancy is not self-limited in its growth, is capable of invading into adjacent tissues, and may be capable of spreading to distant tissues. A benign tumor has none of those properties. Malignancy in cancers is characterized by anaplasia, invasiveness, and metastasis. Malignant tumors are also characterized by genome instability, so that cancers, as assessed by whole genome sequencing, frequently have between 10,000 and 100,000 mutations in their entire genomes. Cancers usually show tumour heterogeneity, containing multiple subclones. They also frequently have reduced expression of DNA repair enzymes due to epigenetic methylation of DNA repair genes or altered microRNAs that control DNA repair gene expression. Tumours can be detected through the visual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Fabric
Synthetic things are composed of multiple parts, often with the implication that they are artificial. In particular, 'synthetic' may refer to: Science * Synthetic chemical or compound, produced by the process of chemical synthesis * Synthetic organic compounds synthetic chemical compounds based on carbon (organic compounds). * Synthetic peptide * Synthetic biology * Synthetic elements, chemical elements that are not naturally found on Earth and therefore have to be created in experiments Industry * Synthetic fuel * Synthetic oil * Synthetic marijuana * Synthetic diamond * Synthetic fibers, cloth or other material made from other substances than natural (animal, plant) materials Other * Synthetic position, a concept in finance * Synthetic-aperture radar, a type or radar * Analytic–synthetic distinction, in philosophy * Synthetic language in linguistics, inflected or agglutinative languages * Synthetic intelligence a term emphasizing that true intelligence expressed by comput ...

Chiffon (fabric)
Chiffon (; , , from the French word ' which means "cloth or rag"; Arabic ' transparent, diaphanous, translucent fabric, or gauze; ( ' s.th.) to shimmer through, reveal) is a lightweight, balanced plain-woven sheer fabric, or gauze, like gossamer, woven of alternate S- and Z-twist crepe (high-twist) yarns.Kadolph, Sara J., ed.: ''Textiles'', 10 th edition, Pearson/Prentice-Hall, 2007, , p. 230. The twist in the crepe yarns puckers the fabric slightly in both directions after weaving, giving it some stretch and a slightly rough feel. Characteristics Chiffon is a lightweight fabric which is associated with elegance and luxury; it drapes well and has a shimmery and sheer appearance. Under a magnifying glass, chiffon resembles a fine net or mesh, which gives it some transparency. Chiffon can be produced out of natural and synthetic fibres. Silk chiffon was very expensive, and it is with the development of synthetic chiffon, such as nylon chiffon, polyester chiffon, and rayo ...

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial research pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ( bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serous
In physiology, serous fluid or serosal fluid (originating from the Medieval Latin word ''serosus'', from Latin ''serum'') is any of various body fluids resembling serum, that are typically pale yellow or transparent and of a benign nature. The fluid fills the inside of body cavities. Serous fluid originates from serous glands, with secretions enriched with proteins and water. Serous fluid may also originate from mixed glands, which contain both mucous and serous cells. A common trait of serous fluids is their role in assisting digestion, excretion, and respiration. In medical fields, especially cytopathology, serous fluid is a synonym for effusion fluids from various body cavities. Examples of effusion fluid are pleural effusion and pericardial effusion. There are many causes of effusions which include involvement of the cavity by cancer. Cancer in a serous cavity is called a serous carcinoma. Cytopathology evaluation is recommended to evaluate the causes of effusions in these cav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dermatology
Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems. Etymology Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία '' -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al.

Ulcer
An ulcer is a discontinuity or break in a bodily membrane that impedes normal function of the affected organ. According to Robbins's pathology, "ulcer is the breach of the continuity of skin, epithelium or mucous membrane caused by sloughing out of inflamed necrotic tissue." Common forms of ulcers recognized in medicine include: * Ulcer (dermatology), a discontinuity of the skin or a break in the skin. ** Pressure ulcers, also known as bedsores ** Genital ulcer, an ulcer located on the genital area ** Ulcerative dermatitis, a skin disorder associated with bacterial growth often initiated by self-trauma ** Anal fissure, a.k.a. an ulcer or tear near the anus or within the rectum ** Diabetic foot ulcer, a major complication of the diabetic foot * Corneal ulcer, an inflammatory or infective condition of the cornea * Mouth ulcer, an open sore inside the mouth. ** Aphthous ulcer, a specific type of oral ulcer also known as a canker sore * Peptic ulcer, a discontinuity of the gastroint ...
