摘要:
The present invention relates to hose reel carts for handling and storage of flexible hoses, such as garden or air hoses. The hose reel cart is primarily constructed of plastic components having a centrally rotatable spool for winding of the flexible hose, a frame for supporting the spool and a multi-position crank arm assembly allowing the consumer to place the crank handle in a lowered position or a raised position. The crank remotely drives the spool, for winding the hose, through a series of gears located within the crank arm assembly. The device may further include a reciprocating guide assembly that operates during rotation of the spool to rewind the hose into a compact configuration.

摘要:
Recombinant respiratory syncytial virus (RSV) are provided which express one or more immune modulatory molecules. The recombinant virus is modified by addition or substitution of a polynucleotide sequence encoding the immune modulatory molecule, which is preferably a cytokine. Introduction of the cytokine increase, decrease, or otherwise enhances aspects of viral biology and/or host immune responses to RSV to facilitate vaccine use of the virus. Cytokines for use within the invention include but are not limited to interleukin 2 (IL-2), interleukin 4 (IL-4), interleukin 5 (IL-5), interleukin 6 (IL6), or interleukin 18 (IL-18), tumor necrosis factor (TNF) alpha, interferon gamma (IFN), and granulocyte-macrophage colony stimulating factor (GM-CSF). The polynucleotide or immune modulatory molecule is preferably added or substituted into the recombinant viral genome or antigenome, typically at an intergenic or other non-coding site, as a separate gene but may be otherwise expressed, for example as a fusion protein.
