Pye Ltd. was an electronics company founded in Cambridge, England, now wholly owned by Philips.
W.G. Pye & Co. Ltd. was founded in 1896 in Cambridge by William George Pye, an employee of the Cavendish Laboratory, as a part-time business making scientific instruments. By the outbreak of World War I in 1914 the company employed 40 people manufacturing instruments that were used for teaching and research. The war increased demand for such instruments and the War Office needed experimental thermionic valves. The manufacture of these components afforded the company the technical knowledge that it needed to develop the first wireless receiver when the first UK broadcasts were made by the British Broadcasting Company in 1922. Instruments continued to be designed and manufactured under W G Pye Ltd, later situated in York Street Cambridge, while a separate company was started to build wireless components in a factory at Church Path, Chesterton.
A series of receivers made at Church Path were given positive reviews by Popular Wireless magazine. In 1924, Harold Pye, the son of the founder, and Edward Appleton, his former tutor at St John's College, Cambridge, designed a new series of receivers which proved even more saleable. In 1928 William Pye sold the company, now renamed Pye Radio Ltd., to C. O. Stanley, who established a chain of small component-manufacturing factories across East Anglia.
A private company limited by shares, usually called a private limited company (Ltd.) (though this can theoretically also refer to a private company limited by guarantee), is the private limited type of company incorporated under the laws of England and Wales, Scotland, that of certain Commonwealth countries and the Republic of Ireland. It has shareholders with limited liability and its shares may not be offered to the general public, unlike those of a public limited company (plc).
"Limited by shares" means that the company has shareholders, and that the liability of the shareholders to creditors of the company is limited to the capital originally invested, i.e. the nominal value of the shares and any premium paid in return for the issue of the shares by the company. A shareholder's personal assets are thereby protected in the event of the company's insolvency, but money invested in the company will be lost.
A limited company may be "private" or "public". A private limited company's disclosure requirements are lighter, but for this reason its shares may not be offered to the general public (and therefore cannot be traded on a public stock exchange). This is the major distinguishing feature between a private limited company and a public limited company. Most companies, particularly small companies, are private.

Leukotriene D4 (LTD4) is one of the leukotrienes. Its function main in the body is to induce the contraction of smooth muscle, resulting in bronchoconstriction and vasoconstriction. It also increases vascular permeability. LTD-4 is released by basophils. Other leukotrienes that function in a similar manner are leukotrienes C4 and E4. Pharmacological agents that inhibit the function of these leukotrienes are leukotriene receptor antagonists (e.g. Zafirlukast, montelukast) and are useful for asthmatic individuals.
