pavlov

Ivan Pavlov believed that hypnosis was a "partial sleep". He observed that the various degrees of hypnosis did not significantly differ physiologically from the waking state and hypnosis depended on insignificant changes of environmental stimuli. http://www.soulcast.com/Louis_J_Sheehan_Esquire_१ Pavlov also suggested that lower-brain-stem mechanisms were involved in hypnotic conditioning.

Currently a more popular "hyper-suggestibility theory" states that the subject focuses attention by responding to the hypnotist's suggestion. As attention is focused and magnified, the hypnotist's words are gradually accepted without the subject conducting any conscious censorship of what is being said. This is not unlike the athlete listening to the coach's last pieces of advice minutes before an important sport event; concentration filters out all that is unimportant and magnifies what is said about what really matters to the subject.

Margaret Hilda Thatcher, Baroness Thatcher, LG, OM, PC, FRS (née Roberts; born 13 October 1925) is a British politician, who was Prime Minister of the United Kingdom from 1979 to 1990 and Leader of the Conservative Party from 1975 to 1990. She is the first and to date only woman to hold either post.http://louis-j-sheehan.biz

Born in Grantham in Lincolnshire, England, she went on to read Chemistry at Somerville College, Oxford. She was selected as Conservative candidate for Finchley in 1958 and won the seat in the general election the following year. Upon the election of Edward Heath in 1970, Thatcher was appointed Secretary of State for Education and Science. In 1974, she backed Sir Keith Joseph for the Conservative party leader, but after falling short he dropped out of the race. Thatcher entered herself and became leader of the Conservative party in 1975. As the Conservative party maintained leads in most polls, Thatcher went on to become Britain's Prime Minister in the 1979 General Election. http://louis-j-sheehan.biz

Thatcher's tenure as Prime Minister was the longest since that of Lord Salisbury and was the longest continuous period in office since the tenure of Lord Liverpool who was Prime Minister in the early 19th century.[1] She was the first woman to lead a major political party in the UK, and the first of only three women to have held any of the four great offices of state. Among other things, she defiantly opposed the Soviet Union, and her tough-talking rhetoric gained her the nickname the "Iron Lady".[1] She currently has a life peerage as Baroness Thatcher, of Kesteven in the County of Lincolnshire, which entitles her to sit in the House of Lords.

dandruff Louis J. Sheehan, Esquire 18882

s the epidermal layer continually replaces itself, cells are pushed outward where they eventually die and flake off. In most people, these flakes of skin are too small to be visible. However, certain conditions cause cell turnover to be unusually rapid, especially in the scalp. For people with dandruff, skin cells may mature and be shed in 2 - 7 days, as opposed to around a month in people without dandruff. The result is that dead skin cells are shed in large, oily clumps, which appear as white or grayish patches on the scalp, skin, and clothes. http://louis1j1sheehan1.blogspot.com

Dandruff has been shown to be the result of three required factors:[1]

1. Skin oil commonly referred to as sebum or sebaceous secretions[2]
2. The metabolic by-products of skin micro-organisms (most specifically Malassezia yeasts)[3][4][5][6][7]
3. Individual susceptibility

Common older literature cites the fungus Malassezia furfur (previously known as Pityrosporum ovale) as the cause of dandruff. While this fungus is found naturally on the skin surface of both healthy people and those with dandruff, it was discovered that a scalp specific fungus, Malassezia globosa, is the responsible agent.[8] This fungus metabolizes triglycerides present in sebum by the expression of lipase, resulting in a lipid byproduct oleic acid (OA). Penetration by OA of the top layer of the epidermis, the stratum corneum, results in an inflammatory response in susceptible persons which disturbs homeostasis and results in erratic cleavage of stratum corneum cells.[5]

Rarely, dandruff can be a manifestation of an allergic reaction to chemicals in hair gels/sprays, hair oils, or sometimes even dandruff medications like ketoconazole.

There is no convincing evidence that food (such as sugar or yeast), excessive perspiration, or climate have any role in the pathogenesis of dandruff. However, certain oily foods or excessive intake of 'junk food' can trigger the appearance of dandruff .


Seborrheic dermatitis

Flaking is a symptom of seborrheic dermatitis. Joseph Bark notes that "Redness and itching is actually seborrheic dermatitis, and it frequently occurs around the folds of the nose and the eyebrow areas, not just the scalp." Dry, thick, well-defined lesions consisting of large, silvery scales may be traced to the less common psoriasis of the scalp.

Seasonal changes, stress, and immuno-suppression seem to affect seborrheic dermatitis.

[edit] Treatment of fungal infection

There have been many strategies for the control of dandruff. Simply increasing shampooing will remove flakes.[9] However, elimination of the fungus results in dramatic improvement. Regular shampooing with an anti-fungal product can reduce recurrence.
