  • Publication number: 20150274798
    Abstract: There are provided a novel series of peptide analogs of hGH-RH(1-29)NH2 and hGH-RH(1-30)NH2 which show high activities in stimulating the release of pituitary GH in animals. They retain their physiological activity in solution for extended periods of time and resist enzymic degradation in the body. These novel and useful properties appear to be due to novel substitution patterns ant at the 1, 15, 27 and 29 positions on the peptide.

  • Publication number: 20140282839
    Abstract: A unified enrollment client is described that allows authentication and communication with disparate enterprise management source types. A first enterprise management source type can have a corporate-based management server which is on the premises of the corporation. A second enterprise management source type can have a cloud-based management server in which a corporate server communicates through a federation gateway to a cloud-based management server. Authentication can be handled regardless of the source type through the use of a discovery request which identifies the source type so that the enrollment client knows how to tailor the authentication, if any is needed, to the particular enterprise management source.

  • Publication number: 20140282460
    Abstract: A method and apparatus are described for unenrolling applications, such as from a mobile device. An enterprise can be associated with one or more applications. Rather than uninstalling the applications individually, a single unenroll user interface command can be used to remove all data on the mobile device associated with the enterprise. Moreover, the applications associated with the enterprise can be uninstalled. A user's personal data on the mobile device is not affected during the unenrollment.

  • Publication number: 20140282836
    Abstract: When receiving multiple security policy configurations from different management sources, a computer device can apply the most secure of the policy configurations to the device. If one of the policy configurations is removed from the device, a determination can be made regarding which of the remaining security policy configurations is the most secure. Once the determination is made, one of the remaining security policies that is the most secure is applied.

  • Publication number: 20140206836
    Abstract: There is provided a novel series of synthetic analogs of hGH-RH(1-29)NH2 (SEQ ID NO: 1) and hGH-RH(1-30)NH2. Of particular interest are those carrying PhAc, N-Me-Aib, Dca, Ac-Ada, Fer, Ac-Amc, Me-NH-Sub, PhAc-Ada, Ac-Ada-D-Phe, Ac-Ada-Phe, Dca-Ada, Dca-Amc, Nac-Ada, Ada-Ada, or CH3—(CH2)10—CO-Ada, at the N-Terminus and ?-Ala, Amc, Apa, Ada, AE2A, AE4P, ?-Lys(?-NH2), Agm, Lys(Oct) or Ahx, at the C-terminus. These analogs inhibit the release of growth hormone from the pituitary in mammals as well as inhibit the proliferation of human cancers, and inhibit the hyperplastic and benign proliferative disorders of various organs, through a direct effect on the cancerous and non-malignant cells. The stronger inhibitory potencies of the new analogs, as compared to previously described ones, result from replacement of various amino acids.

  • Patent number: 8713772
    Abstract: A fastening device for manufacturing a fastening system is disclosed. The fastening system includes a first connecting member, a second connecting member, a rivet riveting the first connecting member and the second connecting member together, and an elastic member compressed by the rivet. The fastening device includes a rivet head forming tool, a positioning assembly positioning the first connecting member, a first driving assembly driving the rivet head forming tool to move, a second driving assembly driving the second connecting member to rotate, and a force measuring module. The force measuring module is configured for measuring the positive pressing force between the first connecting member and the second connecting member, and generating a control signal to stop the first driving assembly and the second driving assembly when the positive pressing force between the first connecting member and the second connecting member reach the predetermined force.
