Abstract: An impeller, and a pump and a fluid delivery device using the pump are disclosed. An impeller includes an base plate and a plurality of long blades and a plurality of short blades disposed on the base plate. The impeller further includes a shaft mounting portion disposed on the base plate. The plurality of long blades and the plurality of short blades are alternatively arranged on the base plate and surround the shaft mounting portion. The long blades and the short blades are all arcuate blades. The above fluid delivery device, the pump and the impeller have improved efficiency.

Abstract: A new Lactobacillus mali that can be used for preventing or treating a metabolic syndrome is provided. A method for preventing or treating obesity, diabetes or a complication of diabetes by using the Lactobacillus mali is also provided.

Abstract: A noise reduction diffuser for an electric blower has a motor holder and a rear cover fitted to the motor holder. The motor holder includes a sidewall and a bottom portion at one end of the sidewall. The other end of the sidewall has an opening for mounting an electric motor inside the sidewall. An output shaft of the motor extends through the bottom portion for driving a fan. The motor holder and the rear cover form a Helmholtz resonance cavity.

Abstract: The invention relates to a probiotic composition for reducing uremic toxins and the manufacturing method thereof. The probiotic composition comprises at least one selected from the group consisting of: Lactobacillus plantarum BCRC 12251, Lactobacillus paracasei BCRC 12188, Streptococcus thermophilus BCRC 13869 and pharmaceutically acceptable vehicles, excipients, diluents, adjuvants, etc. The invention further relates to a probiotic composition consisted of Lactobacillus plantarum BCRC 12251, Lactobacillus paracasei BCRC 12188, Streptococcus thermophilus BCRC 13869 and pharmaceutically acceptable vehicles, excipients, diluents, adjuvants, etc. In addition, the invention relates to a novel use of the probiotic composition for reducing uremic toxins, wherein the uremic toxins are protein-bound uremic toxins.

Abstract: An axial flow fan blade structure and an axial flow fan thereof. The axial flow fan blade structure includes a fan impeller and an annular body. The fan impeller has a hub and multiple blades. Each blade has a first flow guide face and a second flow guide face opposite to the first flow guide face. The annular body is disposed on the blades. The annular body outward extends from the first and second flow guide faces and is annularly connected with the blades along the blades. The annular body not only is able to increase the strength of the blades of the axial flow fan, but also is able to reduce vibration and noise made by the axial flow fan.

Abstract: A single-bearing fan structure includes a fan frame having a bearing cup with a bearing received therein, the bearing cup having a radially inward protruded lip portion formed at a first end to abut on a top of the bearing, and a groove internally formed at a second end; a blade hub having a rotary shaft fixedly connected thereto with a distal end of the rotary shaft inserted into the bearing; a retainer engaged with the groove; a first elastic element fitted around the rotary shaft and located between the blade hub and the bearing; and a second elastic element received in the bearing cup and located between the bearing and the retainer. The first and second elastic elements and the bearing respectively axially and radially support the blade hub, enabling the fan structure to operate stably and have extended service life.

Abstract: The present invention relates to a method for preparing alginate capsules, including incorporating at least one prebiotic and at least one pancreatic digested protein in the wall of an alginate capsule. The present invention also relates to the alginate capsules prepared by the method.

Abstract: A method for transforming rice plants to express heterologous DNA which involves the biolistic bombardment of mature rice seeds (embryo bearing) and results in expression of the heterologous DNA coated on the biolistic particle in the post-bombardment embryo. The heterologous DNA may be introduced as a plastid, as opposed to bare DNA. The transformed rice embryo is regenerated into a rice plantlet which can be transferred from greenhouse to field.
