Charles Blackley
Charles Harrison Blackley (5 April 1820 – 4 September 1900) was the discoverer of the mechanism behind allergic rhinitis caused by pollen Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm ..., commonly called hay fever. The isolation of hay fever as a condition had been known since 1819 through the work of John Bostock. Blackley was the first to connect pollen to the condition, and though he held some later discredited views, his insight was an important step in the research of allergens. His most important work was a book titled the ''Experimental Researches on the Causes and Nature of Catarrhus aestivus'', published in 1873. Charles Darwin had read this book and wrote to thank him for it. He was very interested in Blackley’s experiments and in another letter explained tha ...

Allergic Rhinitis
Allergic rhinitis, of which the seasonal type is called hay fever, is a type of inflammation in the nose that occurs when the immune system overreacts to allergens in the air. It is classified as a type I hypersensitivity reaction. Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes. The fluid from the nose is usually clear. Symptom onset is often within minutes following allergen exposure, and can affect sleep and the ability to work or study. Some people may develop symptoms only during specific times of the year, often as a result of pollen exposure. Many people with allergic rhinitis also have asthma, allergic conjunctivitis, or atopic dermatitis. Allergic rhinitis is typically triggered by environmental allergens such as pollen, pet hair, dust, or mold. Inherited genetics and environmental exposures contribute to the development of allergies.

Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bostock (physician)
John Bostock, Jr. FRS (baptised 29 June 1773, died 6 August 1846) was an English physician, scientist and geologist from Liverpool. Life Bostock was a son of Dr. John Bostock, Sr. He spent some time at New College at Hackney where he attended Joseph Priestley's lectures on chemistry and natural philosophy, before graduating in Medicine at the University of Edinburgh and practising medicine in Liverpool. He moved to London in 1817 where he concentrated on general science. In 1819, Bostock was first to accurately describe hay fever as a disease that affected the upper respiratory tract. He lectured on chemistry at Guy's Hospital and was President of the Geological Society of London in 1826 when that body was granted a Royal Charter and Vice President of the Royal Society in 1832. Bostock died of cholera in 1846; He is buried in the Kensal Green Cemetery, London. Works Bostock was one of the first chemical pathologists.

Correspondence Of Charles Darwin
The British naturalist Charles Darwin corresponded with his extended family and with an extraordinarily wide range of people from all over the world. The letters, over 15,000 in all, provide many insights on issues ranging from the origins of key scientific concepts, to religious and philosophical discussions which have continued to the present day. The letters also illuminate many aspects of Darwin and his biography: the development of his ideas; insights into character and health; and private opinions on controversial issues. His letters to the Harvard botanist Asa Gray, for example, show his opinions on slavery and the American Civil War. Darwin relied upon correspondence for much of his scientific work, and also used letters to marshal support for his ideas amongst friends and colleagues. The historian of science Janet Browne has argued that Darwin's ability to correspond daily played a crucial role in the development of his theory and his ability to garner support for it fr ...

People From Bolton
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
