    Central hypotensive effects of the alpha2a-adrenergic receptor subtype (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-08-09
    Description: alpha2-Adrenergic receptors (alpha2ARs) present in the brainstem decrease blood pressure and are targets for clinically effective antihypertensive drugs. The existence of three alpha2AR subtypes, the lack of subtype-specific ligands, and the cross-reactivity of alpha2AR agonists with imidazoline receptors has precluded an understanding of the role of individual alpha2AR subtypes in the hypotensive response. Gene targeting was used to introduce a point mutation into the alpha2aAR subtype in the mouse genome. The hypotensive response to alpha2AR agonists was lost in the mutant mice, demonstrating that the alpha2aAR subtype plays a principal role in this response.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉MacMillan, L B -- Hein, L -- Smith, M S -- Piascik, M T -- Limbird, L E -- HL38120/HL/NHLBI NIH HHS/ -- HL43671/HL/NHLBI NIH HHS/ -- HL48638/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1996 Aug 9;273(5276):801-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Vanderbilt University, Nashville, TN 37232, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8670421" target="_blank"〉PubMed〈/a〉

    Cardiovascular regulation in mice lacking alpha2-adrenergic receptor subtypes b and c (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-08-09
    Description: alpha2-Adrenergic receptors (alpha2ARs) are essential components of the neural circuitry regulating cardiovascular function. The role of specific alpha2AR subtypes (alpha2a, alpha2b, and alpha2c) was characterized with hemodynamic measurements obtained from strains of genetically engineered mice deficient in either alpha2b or alpha2c receptors. Stimulation of alpha2b receptors in vascular smooth muscle produced hypertension and counteracted the clinically beneficial hypotensive effect of stimulating alpha2a receptors in the central nervous system. There were no hemodynamic effects produced by disruption of the alpha2c subtype. These results provide evidence for the clinical efficacy of more subtype-selective alpha2AR drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Link, R E -- Desai, K -- Hein, L -- Stevens, M E -- Chruscinski, A -- Bernstein, D -- Barsh, G S -- Kobilka, B K -- GM07365/GM/NIGMS NIH HHS/ -- HL48638/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1996 Aug 9;273(5276):803-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Physiology, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8670422" target="_blank"〉PubMed〈/a〉

    Sensitivity of depth of maximum and absorption depth of EAS to hadron production mechanism (1985)
    In:  CASI
    Details
    Publication Date: 2016-06-11
    Description: Comparison of experimental data on depth of extensive air showers (EAS) development maximum in the atmosphere, T sub M and path of absorption, lambda, in the lower atmosphere of EAS with fixed particle number in the energy region eV with the results of calculation show that these parameters are sensitive mainly to the inelastic interaction cross section and scaling violation in the fragmentation and pionization region. The data are explained in a unified manner within the framework of a model in which scaling is violated slightly in the fragmentation region and strongly in the pionization region at primary cosmic rays composition close to the normal one and a permanent increase of inelastic interaction cross section. It is shown that, while interpreting the experimental data, disregard of two methodical points causes a systematic shift in T sub M: (1) shower selection system; and (2) EAS electron lateral distribution when performing the calculations on basis of which the transfer is made from the Cerenkov pulse FWHM to the depth of shower maximum, T sub M.

    Resilient seal ring assembly with spring means applying force to wedge member (1983)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: A ring seal adapted for installation in an annular recess between a housing and a rotating or reciprocating shaft is described. The seal consists of a resilient ring cup member having a ring wedge member inserted in the center recess of the cup member to wedge the opposing lips of the cup member outwardly into a sealing relationship. A spring maintains the force against the wedge member.

    The electromagnetic component of albedo from superhigh energy cascades in dense media (1985)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Albedo from cascades induced in iron by high energy gamma quanta were Monte Carlo simulated. Thereafter the albedo electromagnetic component from proton induced cascades were calculated analytically. The calculations showed that the albedo electromagnetic component increases more rapidly than the nuclear active component and will dominate at sufficiently high energies.

    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: A spherical bearing including an inner ball with an opening for receiving a shaft and a spherical outer surface is described. Features of the bearing include: (1) a circular outer race including a plurality of circumferentially spaced sections extending around the inner ball for snugly receiving the inner ball; and (2) a groove extending circumferentially around the race producing a thin wall portion which permits the opposed side portions to flex relative to the ball for maximizing the physical contact between the inner surface of the race and the spherical outer surface of the ball.

    Mechanical thermal motor (1976)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: An apparatus is described for converting thermal energy such as solar energy into mechanical motion for driving fluid pumps and similar equipment. The thermal motor comprises an inner concentric cylinder carried by a stationary core member. The core member has a cylindrical disc plate fixed adjacent to a lower portion and extending radially from it. An outer concentric cylinder rotatably carried on the disc plate defining a space between the inner and outer concentric cylinders. A spiral tubular member encircles the inner concentric cylinder and is contained within the space between the inner and outer cylinders. One portion is connected to the inner concentric cylinder and a second portion connected to the outer concentric cylinder. A heated fluid is conveyed through the tubular member and is periodically cooled causing the tubular member to expand and contract. This causes the outer concentric cylinder to reciprocally rotate on the base plate accordingly. The reciprocating motion of the outer concentric cylinder is then utilized to drive a pump member in a pump chamber.
