摘要:
Provided herein are compositions designed to reduce or prevent bacterial infections (for example pneuomococcal infections), nasal carriage, nasal colonization, and central nervous system invasion. Provided herein is a composition comprising a pneumococcal neuraminidase, phosphocholine, pneumococcal teichoic acid, pneumococcal lipoteichoic acid, or an antigenic portion of either neuraminidase, phosphocholine, pneumococcal teichoic acid, pneumococcal lipoteichoic acid. Optionally, the composition can comprise any combination of a pneumococcal neuraminidase, a phosphocholine, a pneumococcal teichoic acid, a pneumococcal lipoteichoic acid or an antigenic portion of any one of these. Optionally the agents are detoxified. Further provided are methods of making and using the compositions disclosed herein. Specifically provided are methods of generating antibodies in a subject comprising administering to the subject an agent or composition taught herein. Also provided are methods of reducing or preventing nasal carriage or pneumococcal infection in a subject comprising administering to the subject a composition taught herein.
摘要:
An improved structure for assembling a gear to a shaft to be rotatably mounted in a housing including a rotatable shaft with a projection member radially extending therefrom and with the hub of a gear slidably mounted on the shaft so that one face of the hub of the gear is adjacent to and opposed to one side of the projection member and a fastening member cooperable with such hub face and opposed side of the projection member to restrain rotational movement of the gear relative the shaft.

A nonwoven disposable face mask includes a filtration layer formed of a plurality of thermoplastic microfine meltblown microfibers having an average fiber diameter of less than 1.5 microns. The filtration layer also has a basis weight of less than ten grams per square meter. The resultant face mask provides improved wearer comfort and barrier and filtration properties.
摘要:
A nonwoven laminate fabric includes first and second nonwoven webs formed of spunbonded substantially continuous filaments and a nonwoven web of meltblown microfibers having a basis weight between about one and twenty grams per square meter sandwiched between and bonded to the first and second nonwoven webs to form a composite nonwoven fabric. The meltblown web includes a plurality of thermoplastic microfine fibers having an average fiber diameter of less than 1.5 microns. The nonwoven laminate exhibits good barrier properties and can be used as a sterile wrap.
