Trichophyton Concentricum
''Trichophyton concentricum'' is an anthropophilic dermatophyte believed to be an etiological agent of a type of skin mycosis in humans, evidenced by scaly cutaneous patches on the body known as tinea imbricata. This fungus has been found mainly in the Pacific Islands and South America. Growth and morphology ''Trichophyton concentricum'' produce dense, slow-growing folded colonies which are mostly white to cream colored on Sabouraud's dextrose agar and their hyphae are normally branched, irregular and septate with antler tips resembling T.schoenleinii. The production of conidia is unusual, however when present, microconidia and macroconidia are smooth walled with a diameter of approximately 4 microns and 50 μm respectively. Due to its resemblance to macroconidia, hyphae are sometimes falsely identified as macroconidia. These fungi are also considered to be osmotolerant because of their ability to grown small colonies on 5% NaCl media and are. Hair perforation assays are g ...

Pruritus
An itch (also known as pruritus) is a sensation that causes a strong desire or reflex to scratch. Itches have resisted many attempts to be classified as any one type of sensory experience. Itches have many similarities to pain, and while both are unpleasant sensory experiences, their behavioral response patterns are different. Pain creates a withdrawal reflex, whereas itches leads to a scratch reflex. Unmyelinated nerve fibers for itches and pain both originate in the skin. Information for them is conveyed centrally in two distinct systems that both use the same nerve bundle and spinothalamic tract. Classification Most commonly, an itch is felt in one place. If it is felt all over the body, then it is called ''generalized itch'' or ''generalized pruritus''. Generalized itch is infrequently a symptom of a serious underlying condition, such as cholestatic liver disease. If the sensation of itching persists for six weeks or longer, then it is called ''chronic itch'' or ''ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hill Tribe
Hill people, also referred to as mountain people, is a general term for people who live in the hills and mountains. This includes all rugged land above and all land (including plateaus) above elevation. The climate is generally harsh, with steep temperature drops between day and night, high winds, runoff from melting snow and rain that cause high levels of erosion and thin, immature soils. People have used or lived in the mountains for thousands of years, first as hunter-gatherers and later as farmers and pastoralists. The isolated communities are often culturally and linguistically diverse. Today about 720 million people, or 12% of the world's population, live in mountain regions, many of them economically and politically marginalized. The mountain residents have adapted to the conditions, but in the developing world they often suffer from food insecurity and poor health. They depend on crops, livestock and forest products, and tend to be poor. In the developed world the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Islands
The Pacific islands are a group of islands in the Pacific Ocean. They are further categorized into three major island groups: Melanesia, Micronesia, and Polynesia. Depending on the context, the term ''Pacific Islands'' may refer to one of several concepts: (1) those countries and islands with common Austronesian origins, (2) the islands once (or currently) colonized, (3) the geographical region of Oceania, or (4) any island located in the Pacific Ocean. This list of islands in the Pacific Ocean is organized by archipelago or political boundary. In order to keep this list of moderate size, the more complete lists for countries with large numbers of small or uninhabited islands have been hyperlinked. Name ambiguity and groupings The umbrella term ''Pacific Islands'' has taken on several meanings. Sometimes it is used to refer only to the islands defined as lying within Toa Samoa. At other times, it is used to refer to the islands of the Pacific Ocean that were previously coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitosis
Mitosis () is a part of the cell cycle in eukaryote, eukaryotic cells in which replicated chromosomes are separated into two new Cell nucleus, nuclei. Cell division by mitosis is an equational division which gives rise to genetically identical cells in which the total number of chromosomes is maintained. Mitosis is preceded by the S phase of interphase (during which DNA replication occurs) and is followed by telophase and cytokinesis, which divide the cytoplasm, organelles, and cell membrane of one cell into two new cell (biology), cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic phase (M phase) of a cell cycle—the cell division, division of the mother cell into two daughter cells genetically identical to each other. The process of mitosis is divided into stages corresponding to the completion of one set of activities and the start of the next. These stages are preprophase (specific to plant ce ...

Terbinafine
Terbinafine, sold under the brand name Lamisil among others, is an antifungal medication used to treat pityriasis versicolor, onychomycosis, fungal nail infections, and ringworm including jock itch and athlete's foot. It is either oral administration, taken by mouth or applied to the skin as a cream or ointment. Common side effects when taken by mouth include nausea, diarrhea, headache, cough, rash, and elevated liver enzymes. Severe side effects include liver problems and allergic reactions. Liver injury is, however, unusual. Oral use during pregnancy is not typically recommended. The cream and ointment may result in itchiness but are generally well tolerated. Terbinafine is in the allylamines family of medications. It works by decreasing the ability of fungi to synthesize ergosterol. It appears to result in fungicide, fungal cell death. Terbinafine was discovered in 1991. It is on the WHO Model List of Essential Medicines, World Health Organization's List of Essential Medi ...

Griseofulvin
Griseofulvin is an antifungal medication used to treat a number of types of dermatophytoses (ringworm). This includes fungal infections of the nails and scalp, as well as the skin when antifungal creams have not worked. It is taken by mouth. Common side effects include allergic reactions, nausea, diarrhea, headache, trouble sleeping, and feeling tired. It is not recommended in people with liver failure or porphyria. Use during or in the months before pregnancy may result in harm to the baby. Griseofulvin works by interfering with fungal mitosis. Griseofulvin was discovered in 1939 from the soil fungus '' Penicillium griseofulvum''. It is on the World Health Organization's List of Essential Medicines. Medical uses Griseofulvin is used orally only for dermatophytosis. It is ineffective topically. It is reserved for cases in which topical treatment with creams is ineffective. Terbinafine given for 2 to 4 weeks is at least as effective as griseofulvin given for 6 to 8 weeks f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymerase Chain Reaction
The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study. PCR was invented in 1983 by American biochemist Kary Mullis at Cetus Corporation. Mullis and biochemist Michael Smith (chemist), Michael Smith, who had developed other essential ways of manipulating DNA, were jointly awarded the Nobel Prize in Chemistry in 1993. PCR is fundamental to many of the procedures used in genetic testing and research, including analysis of Ancient DNA, ancient samples of DNA and identification of infectious agents. Using PCR, copies of very small amounts of DNA sequences are exponentially amplified in a series of cycles of temperature changes. PCR is now a common and often indispensable technique used in medical laboratory research for a broad variety of applications including biomedical research and forensic ...

Tinea Corporis
Tinea corporis is a fungal infection of the body, similar to other forms of tinea. Specifically, it is a type of dermatophytosis (or ringworm) that appears on the arms and legs, especially on glabrous skin; however, it may occur on any superficial part of the body. Signs and symptoms It may have a variety of appearances; most easily identifiable are the enlarging raised red rings with a central area of clearing (ringworm). The same appearances of ringworm may also occur on the scalp (tinea capitis), beard area ( tinea barbae) or the groin ( tinea cruris, known as jock itch or dhobi itch). Other classic features of tinea corporis include: * Itching occurs on infected area. * The edge of the rash appears elevated and is scaly to touch. * Sometimes the skin surrounding the rash may be dry and flaky. * Almost invariably, there will be hair loss in areas of the infection. Causes Tinea corporis is caused by a tiny fungus known as dermatophyte. These tiny organisms normally live on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castell
A ''castell'' (: literally, ''castle'') is a human tower built traditionally at festivals in a part of Catalonia (Spain), now also found in the rest of Catalonia, in the Balearic islands and in the Valencian Community. At these festivals, several ''colles castelleres'' (teams that build towers) attempt to build and then dismantle a tower's structure. On 16 November 2010, ''castells'' were declared by UNESCO to be amongst the Masterpieces of the Oral and Intangible Heritage of Humanity. Origin Although based on the earlier traditional Muixeranga of Algemesí in Valencia, the tradition of ''castells'' within Catalonia originated in the ''Ball dels Valencians'' (Valencian Dance) in the town of Valls, near the city of Tarragona, first documented in 1712. Over the course of the 18th century, they spread to other towns and cities in the area, including Vilafranca del Penedès and Tarragona, though it was not until the last 50 years that the practice of building ''castells'' be ...
