Friedrich Christoph Pelizaeus
Friedrich Christoph Pelizaeus (3 April 1851 – 11 August 1942) was a German balneologist and neurologist who was a native of Rietberg. In 1874 he earned his medical doctorate from the University of Würzburg, and afterwards served as an assistant to Karl Friedrich Ferdinand Runge (1835-1882) at the resort in Nassau an der Lahn.

Myelin
Myelin is a lipid-rich material that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon. The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic covering on an electrical wire, myelin does not form a single long sheath over the entire length of the axon. Rather, myelin sheaths the nerve in segments: in general, each axon is encased with multiple long myelinated sections with short gaps in between called nodes of Ranvier. Myelin is formed in the central nervous system (CNS; brain, spinal cord and optic nerve) by glial cells called oligodendrocytes and in the peripheral nervous system (PNS) by glial cells called Schwann cells. In the CNS, axons carry electrical signals from one nerve cell body to another. In the PNS, axons carry signals to muscles and glands or from sens ...

1942 Deaths
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 '' Ab urbe condita''). The denomination 194 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.

Ludwig Merzbacher
Ludwig Merzbacher (9 February 1875 – 30 October 1942) was a German neuropathologist and psychiatrist born in Florence, Italy. In 1900 he received his medical doctorate from the University of Strassburg, afterwards remaining in Strassburg as an assistant at the physiological institute. Later he worked at psychiatric clinics in Freiburg (1902–04) and Heidelberg (1904–06), obtaining his habilitation for psychiatry in 1906 at the University of Tübingen. From 1906 until 1910 he worked at the psychiatric clinic in Tübingen, where he was an assistant to Robert Gaupp (1870–1953). During this time period, he also spent several months in Munich, conducting research in the laboratory of Alois Alzheimer (1864–1915). Here he performed in-depth analysis on the reaction patterns of scavenger cells ( reactive microglia). In 1910 Merzbacher moved to Argentina, where he was appointed head of the laboratory in the psychiatric clinic at Buenos Aires. From 1914 to 1919 he was in c ...

Neuropathologist
Neuropathology is the study of disease of nervous system tissue, usually in the form of either small surgical biopsies or whole-body autopsies. Neuropathologists usually work in a department of anatomic pathology, but work closely with the clinical disciplines of neurology, and neurosurgery, which often depend on neuropathology for a diagnosis. Neuropathology also relates to forensic pathology because brain disease or brain injury can be related to cause of death. Neuropathology should not be confused with neuropathy, which refers to disorders of the nerves themselves (usually in the peripheral nervous system) rather than the tissues. In neuropathology, the branches of the specializations of nervous system as well as the tissues come together into one field of study. Methodology The work of the neuropathologist consists largely of examining autopsy or biopsy tissue from the brain and spinal cord to aid in diagnosis of disease. Tissues are also observed through the eyes, muscle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelizaeus–Merzbacher Disease
Friedrich Christoph Pelizaeus, Pelizaeus–Ludwig Merzbacher, Merzbacher disease is an X-linked neurological disorder that damages oligodendrocytes in the central nervous system. It is caused by mutations in proteolipid protein 1 (''PLP1''), a major myelin protein. It is characterized by a decrease in the amount of insulating myelin surrounding the nerves (hypomyelination) and belongs to a group of genetic diseases referred to as leukodystrophies. Signs and symptoms The hallmark signs and symptoms of Pelizaeus–Merzbacher disease include little or no movement in the arms or legs, respiratory difficulties, and characteristic horizontal movements of the eyes left to right. The onset of Pelizaeus–Merzbacher disease is usually in early infancy. The most characteristic early signs are pathologic nystagmus, nystagmus (rapid, involuntary, rhythmic motion of the eyes) and hypotonia, low muscle tone. Motor abilities are delayed or never acquired, mostly depending upon the severity of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Nervous System
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts. It is a structure composed of nervous tissue positioned along the rostral (nose end) to caudal (tail end) axis of the body and may have an enlarged section at the rostral end which is a brain. Only arthropods, cephalopods and vertebrates have a true brain (precursor structures exist in onychophorans, gastropods and lancelets). The rest of this article exclusively discusses the vertebrate central nervous system, which is radically distinct from all other animals. Overview In vertebrates, the brain and spinal cord are both enclosed in the meninges. The meninges provide a barrier to chemicals ...

Kassel
Kassel (; in Germany, spelled Cassel until 1926) is a city on the Fulda River in northern Hesse, Germany. It is the administrative seat of the Regierungsbezirk Kassel and the district of the same name and had 201,048 inhabitants in December 2020. The former capital of the state of Hesse-Kassel has many palaces and parks, including the Bergpark Wilhelmshöhe, which is a UNESCO World Heritage Site. Kassel is also known for the ''documenta'' exhibitions of contemporary art. Kassel has a public university with 25,000 students (2018) and a multicultural population (39% of the citizens in 2017 had a migration background). History Kassel was first mentioned in 913 AD, as the place where two deeds were signed by King Conrad I. The place was called ''Chasella'' or ''Chassalla'' and was a fortification at a bridge crossing the Fulda river. There are several yet unproven assumptions of the name's origin. It could be derived from the ancient ''Castellum Cattorum'', a castle of the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balneologist
Balneotherapy ( la, balneum "bath") is a method of treating diseases by bathing, a traditional medicine technique usually practiced at spas. Since ancient times, humans have used hot springs, public baths and thermal medicine for therapeutic effects. While it is considered distinct from hydrotherapy, there are some overlaps in practice and in underlying principles. Balneotherapy may involve hot or cold water, massage through moving water, relaxation, or stimulation. Many mineral waters at spas are rich in particular minerals such as silica, sulfur, selenium, and radium. Medicinal clays are also widely used, a practice known as 'fangotherapy'. Definition and characteristics "Balneotherapy" is the practice of immersing a subject in mineral water or mineral-laden mud; it is part of the traditional medicine of many cultures and originated in hot springs, cold water springs, or other sources of such water, like the Dead Sea. Presumed effect on diseases Balneotherapy may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
