Pathologist
Pathology is the study of the causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be " pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in cardiomy ...

Congenital Epulis
Congenital epulis is a proliferation of cells most frequently occurring on the alveolar ridge of the upper jaw at birth. Less frequently, the mass may arise from the mandibular alveolus. Rare cases can arise from the tongue. This lesion is more commonly found in female babies, suggesting hormonal involvement during embryonic development. The cause of this type of epulis is unknown. Also known as congenital granular cell tumor or Neumann's tumor; historically referred to as granular cell myoblastoma. Multiple lesions occur in 10% of affected neonates. The tumor is typically pedunculated and varies in maximum size from 0.5 cm to 9 cm. The lesion is typically painless and does not increase in size after discovery. Some small lesions may regress over time. Treatment is surgical excision. Recurrence is extremely rare even after incomplete excision. References *Kahn, Michael A.

Georges Hayem
Georges Hayem (25 November 1841 – 28 August 1933) was a physician and hematologist born in Paris. He studied medicine in Paris, and later became a professor of therapy and materia medica. Beginning in 1878 he practiced medicine at the Hôpital Tenon; later on, he was associated with the Hôpital St. Antoine. From 1893 until 1911 he held the chair of clinical medicine. Georges Hayem was a pioneer in the field of hematology, and is remembered for his studies on the formation of leukocytes and erythrocytes. He performed the first accurate count of blood platelets, and is credited with developing a solution of mercury bichloride, sodium chloride and sodium sulfate for dilution of blood prior to counting erythrocytes with a hemocytometer. In 1874 he provided an early description of chronic interstitial hepatitis. With bacteriologist Georges-Fernand Widal (1862–1929), the eponymous "Hayem-Widal syndrome" is named, which is an historical term for acquired hemolytic anemia. A ...

Georges Pouchet
Charles Henri Georges Pouchet (26 February 1833 – 29 March 1894) was a French naturalist and anatomist. Life He was born in Rouen, the son of naturalist Félix Archimède Pouchet (1800–1872).

Paul Ehrlich
Paul Ehrlich (; 14 March 1854 – 20 August 1915) was a Nobel Prize-winning German physician and scientist who worked in the fields of hematology, immunology, and antimicrobial chemotherapy. Among his foremost achievements were finding a cure for syphilis in 1909 and inventing the precursor technique to Gram staining bacteria. The methods he developed for staining tissue made it possible to distinguish between different types of blood cells, which led to the ability to diagnose numerous blood diseases. His laboratory discovered arsphenamine (Salvarsan), the first effective medicinal treatment for syphilis, thereby initiating and also naming the concept of chemotherapy. Ehrlich popularized the concept of a magic bullet. He also made a decisive contribution to the development of an antiserum to combat diphtheria and conceived a method for standardizing therapeutic serums. In 1908, he received the Nobel Prize in Physiology or Medicine for his contributions to immunology. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artur Pappenheim
Artur Pappenheim (13 December 1870 in Berlin – 31 December 1916) was a German physician and hematologist, remembered for his pioneer efforts in stem cell research. Biography Of Jewish origins, initially he studied mathematics and philosophy, but his focus later turned to medicine, and in 1895 received his medical degree from the University of Berlin. Subsequently, he became an assistant to Joseph von Mering at the University of Halle, and afterwards worked under neurologist Ludwig Lichtheim in Königsberg.

Claude Bernard
Claude Bernard (; 12 July 1813 – 10 February 1878) was a French physiologist. Historian I. Bernard Cohen of Harvard University called Bernard "one of the greatest of all men of science". He originated the term '' milieu intérieur'', and the associated concept of homeostasis (the latter term being coined by Walter Cannon). Life and career Bernard was born in 1813 in the village of Saint-Julien near Villefranche-sur-Saône. He received his early education in the Jesuit school of that town, and then proceeded to the college at Lyon, which, however, he soon left to become assistant in a druggist's shop. He is sometimes described as an agnostic and even humorously referred to by his colleagues as a "great priest of atheism".

His leisure hours were devoted to the composition of a vaudeville comedy, and the success it achieved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giulio Bizzozero
Giulio Bizzozero (; 20 March 1846 – 8 April 1901) was an Italian doctor and medical researcher.

Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with haematopoiesis, normal blood cell production. Symptoms may include Fatigue, feeling tired, shortness of breath, Bruise, easy bruising and bleeding, and increased risk of infection. Occasionally, spread may occur to the brain, skin, or gums. As an acute leukemia, AML progresses rapidly, and is typically fatal within weeks or months if left untreated. Risk factors include smoking, previous chemotherapy or radiation therapy, myelodysplastic syndrome, and exposure to the chemical benzene. The underlying mechanism involves replacement of normal bone marrow with leukemia cells, which results in a anemia, drop in red blood cells, thrombocytopenia, platelets, and normal leukopenia, white blood cells. Diagnosis is generally based on bone marrow aspiration and specific blood tests. AML has several s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bone Marrow
Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells. In adult humans, bone marrow is primarily located in the ribs, vertebrae, sternum, and bones of the pelvis. Bone marrow comprises approximately 5% of total body mass in healthy adult humans, such that a man weighing 73 kg (161 lbs) will have around 3.7 kg (8 lbs) of bone marrow. Human marrow produces approximately 500 billion blood cells per day, which join the systemic circulation via permeable vasculature sinusoids within the medullary cavity. All types of hematopoietic cells, including both myeloid and lymphoid lineages, are created in bone marrow; however, lymphoid cells must migrate to other lymphoid organs (e.g. thymus) in order to complete ...
