Pierre Masson
Claude L. Pierre Masson (November 12, 1880 – May 11, 1959) was a Canadian medical doctor. He was considered one of the leading histopathologists of his era. He was born in Dijon and studied medicine at the University of Paris and the Pasteur Institute. Originally, Masson planned a career in clinical medicine, but, after suffering poor health, decided to change his area of interest to biology. Masson was offered the chair of pathology at the University of Strasbourg. He is credited with first describing neurocrine secretion and his work led to the development of modern neuroendocrinology. He was also known for his research into brain tumours. Masson developed at three- stain protocol used in histology known as " Masson's trichrome stain". In 1927, he left Strasbourg to become chair of the Pathology department at the Université de Montréal. Masson reworked the pathology curriculum at the university and reorganized the pathology laboratories there. He retired from that posit ...

Burials At Notre Dame Des Neiges Cemetery
Burial, also known as interment or inhumation, is a method of final disposition whereby a dead body is placed into the ground, sometimes with objects. This is usually accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. A funeral is a ceremony that accompanies the final disposition. Humans have been burying their dead since shortly after the origin of the species. Burial is often seen as indicating respect for the dead. It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones, and in many cultures it has been seen as a necessary step for the deceased to enter the afterlife or to give back to the cycle of life. Methods of burial may be heavily ritualized and can include natural burial (sometimes called "green burial"); embalming or mummification; and the use of containers for the dead, such as shrouds, coffins, grave liners, and b ...

Canadian Pathologists
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicians From Dijon
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1880 Births
Year 188 (CLXXXVIII) was a leap year starting on Monday of the Julian calendar. At the time, it was known in the Roman Empire as the Year of the Consulship of Fuscianus and Silanus (or, less frequently, year 941 ''Ab urbe condita''). The denomination 188 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Notre Dame Des Neiges Cemetery
Notre Dame des Neiges Cemetery (french: Cimetière Notre-Dame-des-Neiges) is a rural cemetery located in the borough of Côte-des-Neiges-Notre-Dame-de-Grâce, Montreal, Quebec, Canada which was founded in 1854. The entrance and the grounds run along a part of Côte-des-Neiges Road and up the slopes of Mount Royal. Notre Dame des Neiges Cemetery is the largest cemetery in Canada and the third-largest in North America. History and description Created on property purchased from Dr. Pierre Beaubien, the new cemetery was a response to growing demand at a time when the old Saint-Antoine Cemetery (near present-day Dorchester Square) had become too small to serve Montreal's rapidly increasing population. Founded in 1854 as a garden cemetery in the French style, it was designed by landscape architect Henri-Maurice Perreault, who studied rural cemeteries in Boston and New York. On May 29, 1855, thirty-five-year-old Jane Gilroy McCready, wife of Thomas McCready, then a Montreal municipal c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masson's Trichrome Stain
Masson's trichrome is a three-colour staining procedure used in histology. The recipes evolved from Claude L. Pierre Masson's (1880–1959) original formulation have different specific applications, but all are suited for distinguishing cells from surrounding connective tissue. Most recipes produce red keratin and muscle fibers, blue or green collagen and bone, light red or pink cytoplasm, and dark brown to black cell nuclei. The trichrome is applied by immersion of the fixated sample into Weigert's iron hematoxylin, and then three different solutions, labeled A, B, and C: * Weigert's hematoxylin is a sequence of three solutions: ferric chloride in diluted hydrochloric acid, hematoxylin in 95% ethanol, and potassium ferricyanide solution alkalized by sodium borate. It is used to stain the nuclei. * Solution A, also called plasma stain, contains acid fuchsin, Xylidine Ponceau, glacial acetic acid, and distilled water. Other red acid dyes can be used, e.g. the Biebrich scarle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histopathology
Histopathology (compound of three Greek words: ''histos'' "tissue", πάθος ''pathos'' "suffering", and -λογία '' -logia'' "study of") refers to the microscopic examination of tissue in order to study the manifestations of disease. Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. In contrast, cytopathology examines free cells or tissue micro-fragments (as "cell blocks"). Collection of tissues Histopathological examination of tissues starts with surgery, biopsy, or autopsy. The tissue is removed from the body or plant, and then, often following expert dissection in the fresh state, placed in a fixative which stabilizes the tissues to prevent decay. The most common fixative is 10% neutral buffered formalin (corresponding to 3.7% w/v formaldehyde in neutral buffered water, such as phosphate buf ...

Histology
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Although one may divide microscopic anatomy into ''organology'', the study of organs, ''histology'', the study of tissues, and ''cytology'', the study of cells, modern usage places all of these topics under the field of histology. In medicine, histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. In the field of paleontology, the term paleohistology refers to the histology of fossil organisms. Biological tissues Animal tissue classification There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these four principal tissue types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
