Health Authority
Between 1996 and 2002 the English National Health Service was organised under the following health authorities. In 2002 the health authorities were reorganised and their boundaries changed to constitute 28 strategic health authorities, which were reduced in number to 10 in 2006. Prior to 1996 the service was organised according to regional health authorities. ‡ also included part of High Peak in Derbyshire (East Midlands) These Health Authorities were established in 1996. There were a few changes between then and the final form shown above. There were originally separate authorities for Barnet and Enfield & Haringey, for Bexley & Greenwich and Bromley, for East & North Hertfordshire and South Hertfordshire, and for the Isle of Wight & Portsmouth and South-East Hampshire. Also, the area of Norfolk and Cambridgeshire was partitioned between three authorities : Cambridge & Huntingdon, East Norfolk, and North West Anglia. North West Anglia included from Cambridgeshire: Pete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heth
Heth, sometimes written Chet, but more accurately Ḥet, is the eighth letter of the Semitic abjads, including Phoenician Ḥēt 𐤇 , Hebrew Ḥēth , Aramaic Ḥēth , Syriac Ḥēṯ ܚ, Arabic Ḥā' , and Maltese Ħ, ħ. Heth originally represented a voiceless fricative, either pharyngeal , or velar . In Arabic, two corresponding letters were created for both phonemic sounds: unmodified ' represents , while ' represents . The Phoenician letter gave rise to the Greek eta , Etruscan , Latin H, and Cyrillic И. While H is a consonant in the Latin alphabet, the Greek and Cyrillic equivalents represent vowel sounds, though the letter was originally a consonant in Greek and this usage later evolved into the rough breathing character. Origins The shape of the letter Ḥet ultimately goes back either to the Egyptian hieroglyph for 'courtyard': O6 (compare Hebrew חָצֵר ḥatser of identical meaning, which begins with Ḥet) or to the one for 'thread, wick' represe ...

Hemagglutinin (influenza)
Influenza hemagglutinin (HA) or haemagglutinin .html" ;"title="/sup>">/sup> (British English) is a homotrimeric glycoprotein found on the surface of influenza viruses and is integral to its infectivity. Hemagglutinin is a Class I Fusion Protein, having multifunctional activity as both an attachment factor and membrane fusion protein. Therefore, HA is responsible for binding Influenza virus to sialic acid on the surface of target cells, such as cells in the upper respiratory tract or erythrocytes, causing as a result the internalization of the virus. Secondarily, HA is responsible for the fusion of the viral envelope with the late endosomal membrane once exposed to low pH (5.0-5.5). The name "hemagglutinin" comes from the protein's ability to cause red blood cells (erythrocytes) to clump together (" agglutinate") ''in vitro''. Subtypes Hemagglutinin (HA) in influenza A has at least 18 different subtypes. These subtypes are named H1 through H18. H16 was discovered in 2004 on in ...

Hypochondriasis
Hypochondriasis or hypochondria is a condition in which a person is excessively and unduly worried about having a serious illness. An old concept, the meaning of hypochondria has repeatedly changed. It has been claimed that this debilitating condition results from an inaccurate perception of the condition of body or mind despite the absence of an actual medical diagnosis. An individual with hypochondriasis is known as a hypochondriac. Hypochondriacs become unduly alarmed about any physical or psychological symptoms they detect, no matter how minor the symptom may be, and are convinced that they have, or are about to be diagnosed with, a serious illness. Often, hypochondria persists even after a physician has evaluated a person and reassured them that their concerns about symptoms do not have an underlying medical basis or, if there is a medical illness, their concerns are far in excess of what is appropriate for the level of disease. It is also referred to hypochondriaism which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperandrogenic Anovulation
Polycystic ovary syndrome, or PCOS, is the most common endocrine disorder in women of reproductive age. The syndrome is named after the characteristic cysts which may form on the ovaries, though it is important to note that this is a sign and not the underlying cause of the disorder. Women with PCOS may experience irregular menstrual periods, heavy periods, excess hair, acne, pelvic pain, difficulty getting pregnant, and patches of thick, darker, velvety skin. The primary characteristics of this syndrome include: hyperandrogenism, anovulation, insulin resistance, and neuroendocrine disruption. A review of the international evidence found that the prevalence of PCOS could be as high as 26% among some populations, though ranges between 4% and 18% are reported for general populations. Despite its high prevalence, the exact cause of PCOS remains uncertain and there is no known cure. Definition Two definitions are commonly used: * NIH : In 1990 a consensus workshop sponsore ...

Hydroxylapatite
Hydroxyapatite, also called hydroxylapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH), but it is usually written Ca10(PO4)6(OH)2 to denote that the crystal unit cell comprises two entities. Hydroxyapatite is the hydroxyl endmember of the complex apatite group. The OH− ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system. Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Up to 50% by volume and 70% by weight of human bone is a modified form of hydroxyapatite, known as bone mineral. Carbonated calcium-deficient hydroxyapatite is the main mineral of which dental enamel and dentin are composed. Hydroxyapatite crystals are also found in pathological calcifications such as those found in breast tumors, as w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyaluronan
Hyaluronic acid (; abbreviated HA; conjugate base hyaluronate), also called hyaluronan, is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. It is unique among glycosaminoglycans as it is non-sulfated, forms in the plasma membrane instead of the Golgi apparatus, and can be very large: human synovial HA averages about 7 million Da per molecule, or about 20,000 disaccharide monomers, while other sources mention 3–4 million Da. The average 70 kg (150 lb) person has roughly 15 grams of hyaluronan in the body, one-third of which is turned over (i.e., degraded and synthesized) per day. As one of the chief components of the extracellular matrix, it contributes significantly to cell proliferation and migration, and is involved in the progression of many malignant tumors. Hyaluronic acid is also a component of the group A streptococcal extracellular capsule, and is believed to play a role in virule ...

Hahnium
Dubnium is a synthetic chemical element with the symbol Db and atomic number 105. It is highly radioactive: the most stable known isotope, dubnium-268, has a half-life of about 16 hours. This greatly limits extended research on the element. Dubnium does not occur naturally on Earth and is produced artificially. The Soviet Joint Institute for Nuclear Research (JINR) claimed the first discovery of the element in 1968, followed by the American Lawrence Berkeley Laboratory in 1970. Both teams proposed their names for the new element and used them without formal approval. The long-standing dispute was resolved in 1993 by an official investigation of the discovery claims by the Transfermium Working Group, formed by the International Union of Pure and Applied Chemistry and the International Union of Pure and Applied Physics, resulting in credit for the discovery being officially shared between both teams. The element was formally named ''dubnium'' in 1997 after the town of Dubna, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henan
Henan (; or ; ; alternatively Honan) is a landlocked province of China, in the central part of the country. Henan is often referred to as Zhongyuan or Zhongzhou (), which literally means "central plain" or "midland", although the name is also applied to the entirety of China proper. Henan is a birthplace of Han Chinese civilization, with over 3,200 years of recorded history and remained China's cultural, economic and political center until approximately 1,000 years ago. Henan Province is home to many heritage sites, including the ruins of Shang dynasty capital city Yin and the Shaolin Temple. Four of the Eight Great Ancient Capitals of China, Luoyang, Anyang, Kaifeng and Zhengzhou, are in Henan. The practice of tai chi also began here in Chen Jia Gou Village (Chen style), as did the later Yang and Wu styles. Although the name of the province () means "south of the ellowriver.", approximately a quarter of the province lies north of the Yellow River, also known as the Hu ...
