摘要:
A method of securing vertebrae includes inserting a first pedicle screw into a first pedicle of a first vertebra. The first pedicle screw includes a first channel running perpendicular to a first central axis of the first pedicle screw. The first pedicle screw has a first engagement structure. The method further includes inserting a second pedicle screw into a second pedicle of a second vertebra. The second pedicle screw includes a second channel running perpendicular to a second central axis of the second pedicle screw. The second pedicle screw has a second engagement structure. The method also includes inserting a guidewire through the first and second channels, threading a tether attached to an end of the guidewire through the first and second channels, securing the tether to the first pedicle screw, applying tension to the tether, and securing the tether to the second pedicle screw.

摘要:
Oil-in-water emulsions can be formed using surfactants with biospecific headgroups. Emulsion droplets adhere to surfaces of microorganisms or to various biological surface bearing appropriate adhesins, thus delivering surfactant materials directly to various surfaces. Lipophilic materials and essential oils can be targeted in this way. The emulsions may be incorporated into oral hygiene non-food compositions or compositions for topical application to skin, hair or nails.
摘要:
Oral hygiene antiplaque compositions which include as an active ingredient an amino sugar containing a sugar moiety recognized by lectins on oral bacteria (e.g., .beta.-D-galactose, .beta.-D-N-acetyl galactosamine, L-rhamnose and .beta.-D-fucose) and in which nitrogen is linked to carbon number 1. The amino sugars singly or in combination with each other provide enhanced inhibition of bacterial aggregation, surfactancy, and antimicrobial activity.
摘要:
Oral hygiene antiplaque compositions which include as an active ingredient a glyceroglycolipid having an amine or ether linkage and containing a .beta.-D-galactose moiety (a sugar moiety recognized by lectins on oral bacteria). The compositions containing glyceroglycolipids provide enhanced inhibition of bacterial adhesive interactions and may provide a surfactancy benefit and/or antibacterial benefit.
摘要:
Dentifrice compositions including specific aldobionamides having a .beta.-galactosidic linkage e.g., lactobionamides, which act as antimicrobial agents and/or inhibitors of bacterial adhesion.
