Arnault Tzanck
Arnault Tzanck (1886–1954) was a French physician and a pioneer of blood transfusion. During the First World War, he was a doctor in the military ambulance where he realized the vital role of the blood transfusions. Arnault Tzanck's name is attached to an apparatus he invented that was widely used for transfusing blood in France between the wars, as well as a simple test he devised using the microscopic analysis of scrapings from skin cancer lesions, different ganglia, and some forms of dermatitis especially pemphigus. The Tzanck smear is still widely used as a test for herpes, among other diseases. A deep learning model was developed to analyze Tzanck smears and named after him as ''TzanckNet''. He also experimented with different methods of preserving blood and blood substitutes. Tzanck's most lasting contribution was in the organization of blood transfusion in France that eventually resulted in the creation of the Centre National de Transfusion Sanguine (National Blood Transfus ...

Medicine
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood Transfusion
Blood transfusion is the process of transferring blood products into a person's circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors and platelets. Red blood cells (RBC) contain hemoglobin, and supply the cells of the body with oxygen. White blood cells are not commonly used during transfusion, but they are part of the immune system, and also fight infections. Plasma is the "yellowish" liquid part of blood, which acts as a buffer, and contains proteins and important substances needed for the body's overall health. Platelets are involved in blood clotting, preventing the body from bleeding. Before these components were known, doctors believed that blood was homogeneous. Because of this scientific misunderstanding, many patients died b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deep Learning
Deep learning (also known as deep structured learning) is part of a broader family of machine learning methods based on artificial neural networks with representation learning. Learning can be supervised, semi-supervised or unsupervised. Deep-learning architectures such as deep neural networks, deep belief networks, deep reinforcement learning, recurrent neural networks, convolutional neural networks and Transformers have been applied to fields including computer vision, speech recognition, natural language processing, machine translation, bioinformatics, drug design, medical image analysis, Climatology, climate science, material inspection and board game programs, where they have produced results comparable to and in some cases surpassing human expert performance. Artificial neural networks (ANNs) were inspired by information processing and distributed communication nodes in biological systems. ANNs have various differences from biological brains. Specifically, artificial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marcel Bessis
Marcel Claude Bessis (15 November 1917 – 28 March 1994) was a French physician known for research on blood cells. Bessis was born in Tunis on 15 November 1917. He was educated at the Lycée Janson-de-Sailly in Paris, France. He developed an interest in microscopy in his teenage years and went on to study medicine at the University of Paris. During the Second World War, he served as a military physician and pioneered the technique of exchange transfusion to treat war injuries. He graduated with a medical degree in 1944. Later he studied exchange transfusion as a treatment for hemolytic disease of the newborn, uremia and acute leukemia. He was a frequent collaborator of Jean Bernard. Bessis used electron microscopy and microcinematography to study the structure and function of blood cells—particularly red blood cells, but also platelets and white blood cells, including the abnormal cells found in leukemia. He invented new instruments to aid his research and developed techniq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tzanck Test
In dermatopathology, the Tzanck test, also Tzanck smear, is scraping of an ulcer base to look for Tzanck cells. It is sometimes also called the chickenpox skin test and the herpes skin test. It is a simple, low-cost, and rapid office based test. Tzanck cells (acantholytic cells) are found in: *Herpes simplex * Varicella and herpes zoster *Pemphigus vulgaris *Cytomegalovirus Arnault Tzanck did the first cytological examinations in order to diagnose skin diseases. To diagnose pemphigus, he identified acantholytic cells, and to diagnose of herpetic infections he identified multinucleated giant cells and acantholytic cells. He extended his cytologic findings to certain skin tumors as well. Even though cytological examination can provide rapid and reliable diagnosis for many skin diseases, its use is limited to a few diseases. In endemic regions, Tzanck test is used to diagnose leishmaniasis and leprosy. For other regions, Tzanck test is mainly used to diagnose pemphigus and herpeti ...
