摘要:
Disclosed are nucleic acid molecules which encode heat-stable plant resistance polypeptides having NB-LRR structural motifs, where the polypeptide confers heat-stability to a plant defense response. The invention further involves transgenic plants and transformed host cells that express these nucleic acid molecules and exhibit enhanced disease resistance over a wide range of temperatures.

Disclosed are nucleic acid molecules which encode heat-stable plant resistance polypeptides having NB-LRR structural motifs, where the LRR domain includes a sub-domain which confers heat-stability to a plant defense response. The invention further involves transgenic plants and transformed host cells that express these nucleic acid molecules and exhibit enhanced disease resistance over a wide range of temperatures.

A method for preparing water-soluble tobacco flavor in gel state is disclosed. The method includes the following steps: mixing food thickener with glycerol in a mass ratio of 1:50 to 1:5 and mixing to uniform, heating to a temperature of 80° C. to 100 ° C. and keep stirring till dissolve thoroughly, homogenizing for 5 to 15 minutes, cooling to a temperature of 30° C. to 50° C., adding water-soluble tobacco flavor and mixing to uniform, and placing at least 12 hours at a temperature of 1° C. to 30 ° C. to obtain a final product. The product obtained by the method can greatly inhibit volatilization of the tobacco flavor, maintain fragrance completely, reduce the loss caused by volatile components, and can be easily transported and stored.

A nebulization device having dual modules includes: a nebulization host machine; a three-way tube communicated with the nebulization host machine; and a controller connected to the nebulization host machine; the nebulization host machine further includes a side cover, a nozzle arranged on a lower side of the side cover, a liquid medicine bottle arranged on an upper side of the side cover and communicated with the nozzle, a nebulization sheet arranged on one side of the liquid medicine bottle and communicated with the nozzle, and a first plug-in interface arranged below the liquid medicine bottle; a bottom portion within an interior of the nozzle is provided with a partition plate that divides the interior of the nozzle into an upper nebulization chamber and a lower gas flow chamber.
摘要:
The present invention relates to novel plasmid constructs useful for the delivery of DNA vaccines. The present invention provides novel plasmids having a transcription cassette capable of directing the expression of a vaccine nucleic acid insert encoding immunogens derived from any pathogen, including fungi, bacteria and viruses. The present invention, however, is particularly useful for inducing in a patient an immune response against pathogenic viruses such as HIV, measles or influenza. Immunodeficiency virus vaccine inserts of the present invention express non-infectious HIV virus-like particles (VLP) bearing multiple viral epitopes. VLPs allow presentation of the epitopes to multiple histocompatability types, thereby reducing the possibility of the targeted virus escaping the immune response. Also described are methods for immunizing a patient by delivery of a novel plasmid of the present invention to the patient for expression of the vaccine insert therein. Optionally, the immunization protocol may include a booster vaccination that may be a live vector vaccine such as a recombinant pox virus or modified vaccinia Arbora vector. The booster live vaccine vector includes a transcription cassette expressing the same vaccine insert as the primary immunizing vector.
摘要:
A combined muffler and heat exchanger apparatus is provided. The apparatus includes a housing defining a heat transfer chamber and an acoustic attenuation chamber separated by a partition. A flow regulator and a fluid transport member are disposed within the heat transfer chamber. The flow regulator is adapted to regulate the flow of a first fluid, such as a heat source, between an input end of the housing and the partition. The fluid transport member is adapted to contain the flow of a second fluid. An acoustic regulator is disposed in the acoustic attenuation chamber and extends longitudinally from the partition to an output end of the housing. The acoustic regulator is a metal tube including a plurality of apertures adapted to attenuate exhaust stream acoustics associated with an automotive vehicle power source.
摘要:
In one embodiment, a method includes identifying a first device as being located at a first physical location associated with a meeting, and determining when the first device is no longer located at the first physical location during the meeting. When it is determined that the first device is no longer located at the first physical location during the meeting, the method also includes determining whether to provide a meeting link to the first device, the meeting link being arranged to allow the first device to join the meeting. Finally, the method includes providing the meeting link to the first device if it is determined that the meeting link is to be provided to the first device.
