Arthur Robertson Cushny
Arthur Robertson Cushny Royal Society, FRS FRSE LLD (6 March 1866 – 25 February 1926), was a Scottish pharmacologist and physiologist who became a Fellow of the Royal Society. Life Cushny was born on 6 March 1866 in Fochabers, Moray, Scotland, the fourth son of Rev John Cushny of Speymouth and his wife, Catherine Ogilvie Brown. He attended a local rural school until he enrolled at the University of Aberdeen and received an Master of Arts (Scotland), M.A. in 1886. Then in 1889, he graduated from medical studies at Marischal College, Aberdeen, receiving C.M., M.B. and Doctor of Medicine, M.D. degrees in 1892. Aroused by interests of physiological drug interaction, he traveled to the European continent and spent a year of associated study under Oswald Schmiedeberg at Straßburg, German Empire and six months in Bern under Hugo Kronecker, from whom he learned elements of physiological technique.

Arthur Robertson Cushny 2
Arthur is a masculine given name of uncertain etymology. Its popularity derives from it being the name of the legendary hero King Arthur. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th century Romano-British general who fought against the invading Anglo-Saxons, Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a matter of debate and the poem only survives in a late 13th century manuscript entitled the Book of Aneirin. A 9th-century Breton people, Breton landowner named Arthur witnessed several charters collected in the ''Redon_Abbey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pharmacology
Pharmacology is the science of drugs and medications, including a substance's origin, composition, pharmacokinetics, pharmacodynamics, therapeutic use, and toxicology. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, functions, sources, synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. The two main areas of pharmacology are pharmacodynamics and pharmacokinetics. Pharmacodynamics studies the effects of a drug on biological systems, and pharmacokinetics studies the effects of biological systems on a drug. In broad terms, pharmacod ...

Horticulture
Horticulture (from ) is the art and science of growing fruits, vegetables, flowers, trees, shrubs and ornamental plants. Horticulture is commonly associated with the more professional and technical aspects of plant cultivation on a smaller and more controlled scale than agronomy. There are various divisions of horticulture because plants are grown for a variety of purposes. These divisions include, but are not limited to: propagation, arboriculture, landscaping, floriculture and turf maintenance. For each of these, there are various professions, aspects, tools used and associated challenges -- each requiring highly specialized skills and knowledge on the part of the horticulturist. Typically, horticulture is characterized as the ornamental, small-scale and non-industrial cultivation of plants; horticulture is distinct from gardening by its emphasis on scientific methods, plant breeding, and technical cultivation practices, while gardening, even at a professional level, tends ...

John Horne
John Horne PRSE FRS FRSE FEGS LLD (1 January 1848 – 30 May 1928) was a Scottish geologist. He served as president of the Royal Society of Edinburgh from 1915 to 1919. Life Horne was born on 1 January 1848, in Campsie, Stirlingshire, the son of Janet (''née'' Braid) and James Horne of Newmill, a farmer. He was educated at the High School, Glasgow, and the University of Glasgow where he studied under Lord Kelvin. He left university without graduating at the age on 19. In 1867 he joined the Scottish Branch of HM Geological Survey as an assistant and became an apprentice to Ben Peach. The two soon became good friends and collaborators. Horne was involved in mapping the Central Lowlands. Horne was a logical thinker and writer, complementing Peach's skills of resolving the internal structure of mountains by looking at the surface rocks. Thia approach allowed them to resolve a long-running debate on the "Highlands Controversy" in the 1907 publication of '' The Geological Str ...

Edward Albert Sharpey-Schafer
Sir Edward Albert Sharpey-Schafer (2 June 1850 – 29 March 1935) was a British physiologist. He is regarded as a founder of endocrinology: in 1894 he discovered and demonstrated the existence of adrenaline together with George Oliver, and he also coined the term "endocrine" for the secretions of the ductless glands. Schafer's method of artificial respiration is named after him. Schafer coined the word "insulin" after theorising that absence of a single substance normally produced by the pancreas was responsible for diabetes mellitus. Biography He was born Edward Albert Schäfer, in Hornsey in London, the third son of Jessie Brown and James William Henry Schäfer, a merchant born in Hamburg, who had come to England as a young man, and was a naturalised citizen. His mother was English. The family lived in Highgate in north-west London. Edward was educated at Clewer House School. From 1868 he studied medicine at University College London, where he was taught by the eminent ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thomas Richard Fraser
Sir Thomas Richard Fraser (5 February 1841 – 4 January 1920) was a British physician and pharmacologist. Together with Alexander Crum Brown he discovered the relationship between physiological activity and chemical constitution of the body. Life He was born in Calcutta in India on 5 February 1841, the second son of Mary Palmer and John Richard Fraser, Indian civil servant. Fraser attended the University of Edinburgh Medical School and graduated with an Doctor of Medicine, MD and gold medal in 1862. His award-winning thesis was based on the positive medical applications of physostigmine. This had been discovered by Robert Christison, Sir Robert Christison in 1846 but its suggested uses were largely as a humane killing mechanism rather than as a medical tool.https://www.rcpe.ac.uk/sites/default/files/notable_fellow.pdf In 1869, Fraser was a medical assistant professor at the Edinburgh Royal Infirmary. In 1877, he was a member of an Arctic expedition and later in 1877 was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Renal Tubule
The nephron is the minute or microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and a cup-shaped structure called Bowman's capsule. The renal tubule extends from the capsule. The capsule and tubule are connected and are composed of epithelial cells with a lumen. A healthy adult has 1 to 1.5 million nephrons in each kidney. Blood is filtered as it passes through three layers: the endothelial cells of the capillary wall, its basement membrane, and between the podocyte foot processes of the lining of the capsule. The tubule has adjacent peritubular capillaries that run between the descending and ascending portions of the tubule. As the fluid from the capsule flows down into the tubule, it is processed by the epithelial cells lining the tubule: water is reabsorbed and substances are exchanged (some are added, others are removed); first with the in ...

Glomerulus (kidney)
The glomerulus (: glomeruli) is a network of small blood vessels (capillaries) known as a ''tuft'', located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons. The tuft is structurally supported by the mesangium (the space between the blood vessels), composed of Intraglomerular mesangial cell, intraglomerular mesangial cells. The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its Ultrafiltration (renal), filtrate of water and soluble substances to a cup-like sac known as Bowman's capsule. The filtrate then enters the Nephron#Renal tubule, renal tubule of the nephron. The glomerulus receives its blood supply from an afferent arteriole of the renal arterial circulation. Unlike most capillary beds, the glomerular capillaries exit into efferent arterioles rather than venules. The resistance of the efferent arterioles causes sufficient hydrostatic pressure within th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chirality (chemistry)
In chemistry, a molecule or ion is called chiral () if it cannot be superposed on its mirror image by any combination of rotation (geometry), rotations, translation (geometry), translations, and some Conformational isomerism, conformational changes. This geometric property is called chirality (). The terms are derived from Ancient Greek (''cheir'') 'hand'; which is the canonical example of an object with this property. A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when reacting with other chiral compounds. They also have the same physics, physical properties, except that they often have opposite optical activity, optical activities. A homogeneous mixture of the two enantiomers in equal parts is said to be racemic mixture, racem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
