Fracastoro
Girolamo Fracastoro ( la, Hieronymus Fracastorius; c. 1476/86 August 1553) was an Italian physician, poet, and scholar in mathematics, geography and astronomy. Fracastoro subscribed to the philosophy of atomism, and rejected appeals to hidden causes in scientific investigation. His studies of the mode of syphilis transmission are an early example of epidemiology. Life Fracastoro was born in Verona, Republic of Venice and educated at Padua where at the age of 19 he was appointed professor at the university. On account of his eminence in the practice of medicine, he was elected physician of the Council of Trent. A bronze statue was erected in his honor by the citizens of Padua, while his native city commemorated their great compatriot with a marble statue. He lived and practised in his hometown. In 1546 he proposed that epidemic diseases are caused by transferable tiny particles or "spores" that could transmit infection by direct contact, indirect contact, or even without contac ...

Germ Theory
The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or "germs" can lead to disease. These small organisms, too small to be seen without magnification, invade humans, other animals, and other living hosts. Their growth and reproduction within their hosts can cause disease. "Germ" refers to not just a bacterium but to any type of microorganism, such as protists or fungi, or even non-living pathogens that can cause disease, such as viruses, prions, or viroids. Diseases caused by pathogens are called infectious diseases. Even when a pathogen is the principal cause of a disease, environmental and hereditary factors often influence the severity of the disease, and whether a potential host individual becomes infected when exposed to the pathogen. Pathogens are disease-carrying agents that can pass from one individual to another, both in humans and animals. Infectious diseases are caused by biological ...

Fomite
A fomite () or fomes () is any inanimate object that, when contaminated with or exposed to infectious agents (such as pathogenic bacteria, viruses or fungi), can transfer disease to a new host. Transfer of pathogens by fomites A fomite is any inanimate object (also called passive vector) that, when contaminated with or exposed to infectious agents (such as pathogenic bacteria, viruses or fungi), can transfer disease to a new host. Contamination can occur when one of these objects comes into contact with bodily secretions, like nasal fluid, vomit, or feces. Many common objects can sustain a pathogen until a person comes in contact with the pathogen, increasing the chance of infection. The likely objects are different in a hospital environment than at home or in a workplace. Fomites such as splinters, barbed wire or farmyard surfaces, including soil, feeding troughs or barn beams, have been implicated as sources of virus. Hospital fomites For humans, common hospital fomites are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infectious Diseases
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection. Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune system. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response. Specific medications used to treat infections include antibiotics, antivirals, antifungals, antiprotozoals, and antihelminthics. Infectious diseases resulted in 9.2 million deaths in 2013 (about 17% of all deaths). The branch of medicine that focuses on infections is referred to as infectious disease. Types Infections are caused by infectious agents (pathogens) including: * Bacteria (e.g. ''Mycobacterium tuberculosis'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The I Tatti Renaissance Library
The I Tatti Renaissance Library is a book series published by the Harvard University Press, which aims to present important works of Italian Renaissance Latin Literature to a modern audience by printing the original Latin text on each left-hand leaf (verso), and an English translation on the facing page (recto). The idea was initially conceived by Walter Kaiser, former professor of English and Comparative Literature at Harvard and director of the Villa I Tatti. Its goal is to be the Italian Renaissance version of the Loeb Classical Library. James Hankins, Professor of History at Harvard University, is the General Editor. Many of the books in the series have never been translated into English before, and the series promises to increase the understanding of the Renaissance among the general public and non-specialist historians by making primary sources accessible, thus giving a window into the minds of Renaissance thinkers themselves. The books of The I Tatti Renaissance Library hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syphilis
Syphilis () is a sexually transmitted infection caused by the bacterium ''Treponema pallidum'' subspecies ''pallidum''. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration usually between 1 cm and 2 cm in diameter) though there may be multiple sores. In secondary syphilis, a diffuse rash occurs, which frequently involves the palms of the hands and soles of the feet. There may also be sores in the mouth or vagina. In latent syphilis, which can last for years, there are few or no symptoms. In tertiary syphilis, there are gummas (soft, non-cancerous growths), neurological problems, or heart symptoms. Syphilis has been known as "the great imitator" as it may cause symptoms similar to many other diseases. Syphilis is most commonly spread through sexual activity. It may also be transmi ...

Epidemiology
Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in a defined population. It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results (including peer review and occasional systematic review). Epidemiology has helped develop methodology used in clinical research, public health studies, and, to a lesser extent, basic research in the biological sciences. Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials. ...

Titian Girolamo Fracastoro
Tiziano Vecelli or Vecellio (; 27 August 1576), known in English as Titian ( ), was an Italian (Venetian) painter of the Renaissance, considered the most important member of the 16th-century Venetian school. He was born in Pieve di Cadore, near Belluno. During his lifetime he was often called ''da Cadore'', 'from Cadore', taken from his native region. Recognized by his contemporaries as "The Sun Amidst Small Stars" (recalling the final line of Dante's '' Paradiso''), Titian was one of the most versatile of Italian painters, equally adept with portraits, landscape backgrounds, and mythological and religious subjects. His painting methods, particularly in the application and use of colour, exercised a profound influence not only on painters of the late Italian Renaissance, but on future generations of Western artists. His career was successful from the start, and he became sought after by patrons, initially from Venice and its possessions, then joined by the north Italian p ...

Josuah Sylvester
Josuah Sylvester (1563 – 28 September 1618) was an English poet. Biography Sylvester was the son of a Kentish clothier. In his tenth year he was sent to school at King Edward VI School, Southampton, where he gained a knowledge of French. After about three years at school, he appears to have been put to business, and in 1591 the title-page of his ''Yvry'' states that he was in the service of the Merchant Adventurers' Company. He was for a short time a land steward, and in 1606 Henry Frederick, Prince of Wales gave him a small pension as a kind of court poet. In 1613 he obtained a position as secretary to the Merchant Adventurers. He was stationed at Middelburg, in the Low Countries, where he died. Works He translated into English heroic couplets the scriptural epic of Guillaume du Bartas. His ''Essay of the Second Week'' was published in 1598; and in 1604 ''The Divine Weeks of the World's Birth''. The ornate style of the original offered no difficulty to Sylvest ...

Typhus
Typhus, also known as typhus fever, is a group of infectious diseases that include epidemic typhus, scrub typhus, and murine typhus. Common symptoms include fever, headache, and a rash. Typically these begin one to two weeks after exposure. The diseases are caused by specific types of bacterial infection. Epidemic typhus is due to ''Rickettsia prowazekii'' spread by body lice, scrub typhus is due to ''Orientia tsutsugamushi'' spread by chiggers, and murine typhus is due to ''Rickettsia typhi'' spread by fleas. Vaccines have been developed, but none are commercially available. Prevention is achieved by reducing exposure to the organisms that spread the disease. Treatment is with the antibiotic doxycycline. Epidemic typhus generally occurs in outbreaks when poor sanitary conditions and crowding are present. While once common, it is now rare. Scrub typhus occurs in Southeast Asia, Japan, and northern Australia. Murine typhus occurs in tropical and subtropical areas of the worl ...

Oil Of Guaiac
Oil of guaiac is a fragrance ingredient used in soap and perfumery. Despite its name it does not come from the ''Guaiacum'' tree, but from the palo santo tree (''Bulnesia sarmientoi''). Oil of guaiac is produced through steam distillation of a mixture of wood and sawdust from palo santo. It is sometimes incorrectly called guaiac wood concrete. It is a yellow to greenish yellow semi-solid mass which melts around 40–50 °C. Once melted, it can be cooled back to room temperature yet remain liquid for a long time. Oil of guaiac has a soft roselike odour, similar to the odour of hybrid tea roses or violets. Because of this similarity, it has sometimes been used as an adulterant for rose oil. Oil of guaiac is primarily composed of 42–72% guaiol, bulnesol, δ- bulnesene, β- bulnesene, α-guaiene, guaioxide and β- patchoulene. It is considered non-irritating, non-sensitizing, and non-phototoxic to human skin. Oil of guaiac was also a pre-Renaissance remedy to syphilis. ...
