  • Publication number: 20120284638
    Abstract: A system and method for real-time, social networking, sharing and collaborating is disclosed. An application for the networking, sharing and collaborating is downloaded onto a mobile device, such as a smartphone, or onto a networked computer. Users log into the application and send invitations to other users to form groups for on-line sharing and collaboration. Persons may be invited to join a group via their e-mail addresses, other affinity address, or proximity to each other through a resident global positioning system. Once a group is formed, nearly instantaneous communications are maintained without e-mail or instant messaging systems. Participants may share files, notes, photos, videos, music, contacts and other items with each other and store shared items. Communications take place among group members via dual communications channels.

  • Patent number: 6863881
    Abstract: The present invention provides compositions and methods for identifying agents that stimulate or inhibit nematode reproduction, especially related to oocyte maturation, sheath cell contraction, and ovulation. It is disclosed that the major sperm protein (MSP) is acts in signal transduction of female sexual maturation in nematodes. Provided are compositions and methods for identifying anti-nematode agents with MSP as a target and for controlling nematode populations. MSP is an excellent target for identification of anti-nematode factors because it is highly conserved among members of the phylum Nematoda and is not known to exist in other organisms, especially crops, livestock, pets, and humans. Thus, anti-nematode agents that target MSP are less likely to induce severe side effects when administered to a host and the nematode is unlikely to develop resistance to a highly conserved molecule involved in sexual reproduction.
