A disease in which humans are parasitized by any of four species of blood flukes: <i>Schistosoma mansoni</i>, <i>S. haematobium</i>, <i>S. japonicum</i>, and <i>S. mekongi</i>. In contrast to other trematodes, the sexes are separate; that is, male and female reproductive systems occur in individual worms. The disease is also known as bilharziasis.
Industry:Science
A disease in which the mineralized tissues of the tooth undergo progressive destruction from the outside surface of the tooth. It is caused by bacteria that colonize the tooth surface and, under certain conditions, produce sufficient acids to demineralize the enamel covering of the tooth crown or the cementum covering the root, and then the underlying dentin. As the destruction of the dentin progresses, along with breakdown of the organic components, the bacteria invade the dead tissue and enter the pulp chamber. The pulpal tissue becomes infected and the typical toothache may ensue. The infection can ultimately destroy the pulpal tissue and extend out through the apical openings of the roots and into the surrounding periodontal tissues.
Industry:Science
A disease of children and young adults, characterized by fever and enlarged lymph nodes and spleen. Only in the mid-1970s did accumulated evidence permit clear linkage of this disease to EB (Epstein-Barr) herpesvirus as the causative agent.
Industry:Science
A disease of mammals caused by a specialized group of gram-negative bacteria in the order Rickettsiales, family Anaplasmataceae, genus <i>Anaplasma</i>. <i>Anaplasma</i> is an obligate intracellular parasite that infects erythrocytes (red blood cells) of cattle, sheep, goats, and wild ruminants in much of the tropical and subtropical world. A newly reclassified species that infects the white blood cells of mammals was recently added to this genus. However, the most important species and the one traditionally associated with the disease anaplasmosis is <i>A. marginale</i>. Anaplasmosis is one of the most important diseases of cattle, causing anemia and sometimes death, resulting in significant economic losses worldwide.
Industry:Science
A disease of the eye in which damage is caused by elevated pressure within the eye. The incidence in persons over the age of 40 is about 0.5%, making glaucoma one of the most common and serious eye disorders, surpassed in the United States only by cataracts as a cause of blindness.
Industry:Science
A disease of the nervous system characterized by a progressive dementia that leads to profound impairment in cognition and behavior. Dementia occurs in a number of brain diseases where the impairment in cognitive abilities represents a decline from prior levels of function and interferes with the ability to perform routine daily activities (for example, balancing a checkbook or remembering appointments). Alzheimer's disease is the most common form of dementia, affecting 5% of individuals over age 65. The onset of the dementia typically occurs in middle to late life, and the prevalence of the illness increases with advancing age to include 25–35% of individuals over age 85.
Industry:Science
A disease resulting from an abnormality in neuromuscular transmission, characterized by a fluctuating degree of muscle weakness. The weakness is usually aggravated by activity, and there is partial or complete restoration of strength after a period of rest or the administration of anticholinesterase medications.
Industry:Science
A disk of high-grade quartz glass approximately 2 cm (0.75 in.) thick, having at least one side ground and polished with a deviation in flatness usually not exceeding 0.000002 in. (50 nanometers) all over, and a surface quality of 5 microfinish or less. When two surfaces of this quality are placed lightly together so that the air is not wrung out from between them, they are separated by a film of air and actually touch at only one point. This point is the vertex of a wedge of air separating the two pieces.
Industry:Science
A disorder characterized by the accumulation of an unusual extracellular fibrous protein (amyloid) in the connective tissue of the body. The deposition of amyloid may be widespread, involving major organs and leading to serious clinical consequences, or it may be very limited with little effect on health.
Industry:Science
A dispersion of a pigment or a solution of a dye in a vehicle (carrier), yielding a fluid, paste, or powder that can be applied to and dried on a substrate. Printing, writing, marking, and drawing inks are applied by several methods to paper, metal, plastic, wood, glass, fabric, or other substrates. Inks perform communicative, decorative, and even protective functions.
