Abstract: A method of diagnosing allergic asthma in patients, including the steps of: obtaining from a subject a first sample of peripheral blood immune cells and a second sample of peripheral blood immune cells; adding chitin to the first sample; measuring the average amount of IFN-? in both the first sample and the second sample to get a first value and a second value respectively; and dividing the first value with the second value to get a ratio, wherein if the ratio is smaller than a threshold value, the subject is diagnosed as an allergic asthma patient.

Abstract: The present invention relates to a porous magnetic antenna, comprising: an antenna; an insulating layer, having one side next to said antenna; and a magnetic layer, placed next to the other side of the insulating layer, separated from said antenna with a distance, and having at least one hole. The porous magnetic antenna has the advantages of shaping the field pattern, lowering the sensitivity, improving the gain value and possessing stable directionality.

Abstract: The invention provides small interfering RNA (siRNA) and their carriers that could treat asthma in mammalian through inhibiting acidic mammalian chitinase (AMCase) gene expression. The invention further provides a composition comprising siRNA of the present invention and a carrier. The invention also provides a method for treating asthma of a subject.

Abstract: An intelligent fuel oil monitoring system includes a fuel level detector coupled to a fuel tank of a motor vehicle to detect the amount of the fuel oil in the fuel tank, a microcontroller coupled to the fuel level detector to receive traveling data of the motor vehicle and to establish an average speed-fuel consumption relationship curve and fuel consumption and travel distance relationship curves at different speeds and to calculate the distance the motor vehicle can travel based on the amount of the fuel oil detected by the fuel level detector subject to the fuel consumption and travel distance relationship curve, and a display unit coupled to the microcontroller and controlled by the microcontroller to display data.
