What's the difference between beryllium and gadolinite?

Beryllium


Definition:

  • (n.) A metallic element found in the beryl. See Glucinum.

Example Sentences:

  • (1) Beryllium, cadmium, and tellurium assay data are reported for the fresh tissues of albino rats exposed to inorganic chemicals by oral or intraperitoneal routes.
  • (2) Peak air concentrations of beryllium of as much as 50 times the accepted peak limit value were found in the plant in 1971.
  • (3) Base metal alloys, principally made of nickel, chromium, and beryllium have gained widespread usage, especially in the United States, due to their lower cost and higher mechanical properties.
  • (4) The effects of beryllium addition to a dental cobalt-chromium alloy on biological compatibility as well as physical properties were examined and the following results were obtained.
  • (5) The role of the immune system in the pathogenesis of beryllium lung disease has been suspected for years.
  • (6) The value of the beryllium macrophage migration inhibition (Be MIF) and Mantoux tests in the diagnosis of chronic beryllium disease and in the detection of hypersensitivity in healthy beryllium workers is demonstrated.
  • (7) Association of radiological changes with imperfection of lungs' ventilating reserve of restrictive type was found in one man who was removed from the work in exposure to beryllium, as a person with an increased risk of falling ill.
  • (8) We conclude that use of fiberoptic bronchoscopy with transbronchial biopsy and BAL facilitates diagnosis of beryllium workers who have histopathologic and immunologic alterations consistent with chronic beryllium disease.
  • (9) The possible geometries of aluminum and beryllium fluorides in the gamma-phosphate subsite of the nucleotide are discussed in correlation with the catalytic mechanism of nucleotide hydrolysis.
  • (10) The proposed method is simple (only beryllium and an ammoniacal buffer are needed to develop fluorescence), rapid (the derivative formation is instantaneous and serum treatment only requires deproteinization), and inexpensive (no sophisticated detection equipment is necessary, any conventional modern spectrofluorimeter being adequate for use).
  • (11) A method was devised for attaching beryllium to particulate carriers, such as lymphocytes or red cells that had been fixed with glutaraldehyde.
  • (12) In a simulated 1-year period of mastication, the results showed that nickel and beryllium metals were released both by dissolution and occlusal wear.
  • (13) Beryllium fluoride (BeF3-) has previously been shown to bind tightly to microtubules as a structural analogue of Pi and to mimic the GDP-Pi transient state in tubulin polymerization [Carlier, M.-F., Didry, D., Melki, R., Chabre, M., & Pantaloni, D. (1988) Biochemistry 27, 3555-3559].
  • (14) To obtain the usual values of arsenic, beryllium, bismuth, cadmium, chromium, cobalt, copper, mercury, methyl mercury, manganese, molybdenum, nickel, lead, antimony, vanadium, and zinc in the normal human body, the amounts of 15 metals were determined in 15 male and 15 female Japanese cadavers (average weight, 55 kg [121 lb]).
  • (15) The effects of lung injury in rats and mice exposed to an aerosol of beryllium sulfate for 1 hr through nose-only inhalation were evaluated by the method of bronchoalveolar lavage.
  • (16) The hazards due to the presence of beryllium in numerous alloys is emphasized as well as the necessity of technical and medical supervision in dental laboratories.
  • (17) Most of the beryllium that was cleared from the lungs and not excreted was translocated to the tracheobronchial lymph nodes, skeleton, liver, and blood.
  • (18) No evidence could be obtained of an affinity of beryllium for DNA or RNA by fractionation of nuclei and dialysis experiments.
  • (19) The test was positive in none of the four patients with biopsy evidence of non-beryllium disease, none out of two patients with lower lobe fibrosis suggestive of non-beryllium disease, and all of three patients with probable chronic beryllium lung disease.
  • (20) FCA-treated rabbits developed a much higher serum precipitating antibody response, detectable using gel double diffusion tests, than the beryllium group.

Gadolinite


Definition:

  • (n.) A mineral of a nearly black color and vitreous luster, and consisting principally of the silicates of yttrium, cerium, and iron.
