    Abstract: A molecular motor in which multiple concentric cylinders (or nested cones) rotate around a common longitudinal axis. Opposing complementary surfaces of the cylinders or cones are coated with complementary motor protein pairs (such as actin and myosin). The actin and myosin interact with one another in the presence of ATP to rotate the cylinders or cones relative to one another, and this rotational energy is harnessed to produce work. The concentration of ATP and the number of nested cylinders or cones can be used to control the rotational speed of the motor. The length of the cylinders can also be used to control the power generated by the motor. In another embodiment, the molecular motor includes at least two annular substrates wherein one annular substrate is coated with a first motor protein and the other annular substrate is coated with a second motor protein. The first and second motor proteins interact with each other to move the second annular relative to the first annular substrate.

  • Patent number: 8808978
    Abstract: A method for washing platelets includes introducing anticoagulant into a platelet product container, drawing re-anticoagulated platelet product from the platelet product container, and introducing it into a centrifuge bowl. The centrifuge bowl separates the platelets from the supernatant in which they are suspended. The method then washes the platelets by introducing wash solution into the centrifuge bowl. As the wash solution is introduced into the bowl, it displaces the supernatant from the bowl and into a waste container. The method then introduces platelet additive solution into the centrifuge bowl, which displaces the wash solution from the centrifuge bowl and into the waste container and further wash the platelets. The method then repeatedly accelerates and decelerates the centrifuge bowl to resuspend the platelets in the platelet additive solution.

A first device part (10) maintains a second insoluble carrier (12) and a third insoluble carrier (13) in such a manner that they overlap with each other at a detection portion (14) of a first insoluble carrier (11). These three carriers (11), (12) and (13) are housed not in contact with each other. A pressing unit (18) having a pressing surface (18a) that is parallel to the detection portion (14) is provided on an inner surface of the second device part (20) facing the detection portion (14). The pressing surface (18a) is displaced by being pressed toward the detection portion (14), and presses, from the upper side of the first insoluble carrier (11), the second insoluble carrier (12) and the third insoluble carrier (13) onto the first insoluble carrier (11). The first device part (10) and the second device part (20) are joined together.

  • Patent number: 8802428
    Abstract: It is possible to determine the presence of bacteria in a sample solution in a shorter period of time without changing a conventional incubating method. Bacteria in a sample solution are incubated in, for example, a sterilized agar medium 10 having a layer thickness of 0.1 ?m to 1 ?m formed on an electrode of a crystal resonator 2, and an oscillation frequency is measured. When the bacteria proliferate, the mass of the entire crystal resonator 2 increases, and the oscillation frequency decreases. Therefore, by monitoring presence of such a change over time, presence of bacteria in the sample solution can be determined quickly.

  • Publication number: 20140220665
    Abstract: The present invention relates to an apparatus for mixing cells and exogenous material for delivery of the exogenous material into cells using electroporation in a manner that preserves cell viability and integrity of the exogenous material. The exogenous material can be polynucleotides, peptides, proteins or other pharmaceutical molecules. It further provides a chamber that can be used to electroporate the contents of the chamber after mixing. In accordance with the invention, cell suspensions that may be contaminated with degrading enzymes are stored separately from water-based liquids that contain the exogenous material. Contact of the two water-based liquids (cell suspension and exogenous material) first occurs within the chamber. The chamber of the present invention has two or more inlet ports to allow separate entrance of water-based liquids. Two other ports are vent and exit ports.

  • Patent number: 8798980
    Abstract: A molecular motor in which multiple concentric cylinders (or nested cones) rotate around a common longitudinal axis. Opposing complementary surfaces of the cylinders or cones are coated with complementary motor protein pairs (such as actin and myosin). The actin and myosin interact with one another in the presence of ATP to rotate the cylinders or cones relative to one another, and this rotational energy is harnessed to produce work. The length of the cylinders can also be used to control the power generated by the motor. In another embodiment, the molecular motor includes at least two annular substrates wherein one annular substrate is coated with a first motor protein and the other annular substrate is coated with a second motor protein. The first and second motor proteins interact with each other to move the second annular relative to the first annular substrate.

  • Patent number: 8795957
    Abstract: The present invention provides a blood collection container capable of allowing blood to coagulate in a short time and preventing blood from coagulating with bubbles contained therein and thus preventing formation of bubbly clots when used to collect blood therein. A blood collection container 1 stores a blood coagulation promoting agent 4 for promoting blood coagulation and an antifoaming agent 5, which is a polyoxyalkylene or a derivative thereof. The amount of the antifoaming agent 5 is 2.0×10?3 to 0.2 mg per mL of blood to be collected in the blood collection container 1.

  • Publication number: 20140212446
    Abstract: The invention relates to novel artificial antigen presenting cells (aAPCs). The aAPC comprises at least one stimulatory ligand and at least one co-stimulatory ligand where the ligands each specifically bind with a cognate molecule on a T cell of interest, thereby mediating expansion of the T cell. The aAPC of the invention can further comprise additional molecules useful for expanding a T cell of interest. The aAPC of the invention can be used as an “off the shelf” APC that can be readily designed to expand a T cell of interest. Also, the aAPC of the invention can be used identify the stimulatory, co-stimulatory, and any other factors that mediate growth and expansion of a T cell of interest. Thus, the present invention provides powerful tools for development of novel therapeutics where activation and expansion of a T cell can provide a benefit.
