Abstract: The present invention relates to a method of assisting the diagnosis of metastatic castration resistant prostate cancer, including measuring an amount of an extracellular vesicle having phosphatidylserine and a prostate specific membrane antigen in a biological specimen derived from a subject; and determining whether or not the subject has metastatic castration resistant prostate cancer by using, as an indicator, the amount of the extracellular vesicle having phosphatidylserine and a prostate specific membrane antigen.

Abstract: To obtain data associated with a mitochondrial disease, a method includes measuring the level of at least one protein selected from the group consisting of GDF15 (growth differentiation factor 15), HGF (hepatocyte growth factor), MIG (gamma interferon induction monokine), SCF (stem cell factor) and SCGF-? (stem cell growth factor beta) in a biological sample collected from a subject. The measured protein level is compared to that of control subjects and then it is checked whether or not there is difference between the protein level of the subject and that of control subjects.

Abstract: An ester compound represented by formula (1) R1OOC—(CH2)m—COOR2 ??(1) wherein R1 and R2 are different from each other and each represents a group of formula (2) —(R3O)nR4 ??(2) wherein R3 is a C1-6 alkylene group; R4 is a C1-10 straight- or branched-chain alkyl group, a C6-12 aryl group, C7-15 arylalkyl group or a C7-15 alkylaryl group; m is an integer from 0 to 8, and n is an integer from 0 to 6. This compound is suitable as a plasticizer for biodegradable aliphatic polyester resins.

Abstract: A reciprocating compressor comprising a cylinder block (3) having formed therein a plurality of cylinders (11), a shaft rotatably passing through the cylinder block and pistons engaged in reciprocating movement inside the cylinders (11) as the shaft rotates, which is installed by fastening mounting leg parts (31) disposed at the cylinder block (3) at mounting positions, is characterized in that the mounting leg parts are each constituted with a connecting portion (31a) extending from the cylinder block 3 and a projected portion (31b) formed continuously to the connecting portion to project on one side or both sides of the connecting portion along the tightening direction and that the projected portion (31b) has a lower level of rigidity compared to the connecting portion (31a).

Abstract: The lubrication between a shoe and a shoe pocket is improved without having to perform a complicated forming process. In a swash plate compressor comprising a swash plate locked to a drive shaft, which rotates together with the drive shaft, a shoe 31 that slidably contacts the swash plate, a piston 13 slidably disposed within a bore defining a compression space and a shoe pocket 36 that is formed as an integrated part of the piston 13 and slidably fits with the shoe 31, a beveled portion 41 is formed at an edge of an opening at the shoe pocket 36. A recessed portion 40 of the shoe pocket 36 is formed so as to achieve a constant curvature, whereas a projecting portion 32 of the shoe 31 is formed so as to achieve at least two different curvatures. The shoe pocket is designed so that a tangent point 46 of the recessed portion 40 and the beveled portion 41 is set within a strip range 45 over which the projecting portion 32 and the recessed portion 40 achieve contact with each other.

Abstract: A reciprocating compressor includes a front-side delivery chamber 18a formed at a front-side cylinder head 6, a rear-side delivery chamber 18b formed at a rear-side cylinder head 8, a plurality of delivery passages 12a and 12b formed at cylinder blocks 2 and 4 and an outlet port 16 that communicates between one of the delivery passages and an external circuit. The other delivery passage 12b that is not in communication with the outlet port 16 is made to communicate with the front-side delivery chamber 18a and the rear-side delivery chamber 18b and is also made to communicate with the delivery passage 12a in communication with the outlet port 16 via a guide passage 17.

Abstract: A LED printer utilizing a low resolution print engine for forming high resolution images is disclosed, in which a virtual 2N dpi high density image (latent image) is formed on a photosensitive medium by effectively turn-on controlling an array of LED elements arranged at a pitch of N dpi on a line in the main scanning direction.For each scanning line, a plurality of divisional exposure lines are produced for turning on the LED elements 2 m times (for instance 2.times.4 times) in the auxiliary scanning direction. For the turn-on control of the LED elements, weighted arithmetic operation values are obtained by multiplying the center bit and one or more adjacent bits thereto in the main scanning direction of the 2N dpi high density image data by respectively corresponding constants, and they are summed up to obtain sum data. According to the sum data the number of times of turning on the LED elements on the divisional exposure lines is controlled to form 2N dpi high density image on the photosensitive medium.
