The technique of surface segregation was applied to prepare a bio-inert polymer interface. A small amount, 10 wt%, of poly(2-methoxyethyl acrylate) (PMEA), which exhibits excellent bio-inertness properties, fed into a matrix polymer was able to suppress platelet adhesion sufficiently to be of practical use. PMEA was effective because it was preferentially segregated at the outermost region of the polymer blend. Combining interfacial-sensitive analyses such as the air bubble contact angle and neutron reflectivity measurements and sum-frequency generation spectroscopy with the platelet adhesion test gives a better understanding of how the bio-inert property is expressed at the water interface. © 2015 Published by Elsevier Ltd.

Bartonella quintana bacteremia was detected in 6 (13.3%) of 45 wild-caught Japanese macaques (Macaca fuscata). Multilocus sequence typing of the isolates revealed that Japanese macaques were infected with a new and specific B. quintana sequence type. Free-ranging Japanese macaques thus represent another natural reservoir of B. quintana. © 2015, Centers for Disease Control and Prevention (CDC). All rights reserved.

It is important for each leader to know relationship of the reason why each learner mistakes the problem of Mathematics. But, it does not exist about previous research. Therefore, in this research, we collected answers of each learner for knowing element of difficulty level in Mathematics. And we identified 10 types. 10 types are “lack of understand(problem statement, Number & Symbol, Formula, Concept)”, “circumstances of learner (inside)”, “circumstances of learner (outside)”, “Miscalculation”, “Copy miss”, “Lack of logical thinking (Deduction)” and “Lack of logical thinking (Induction)”. © Springer International Publishing Switzerland 2015.

PURPOSE. To assess the associations between dietary intake of polyunsaturated fatty acids (PUFAs) and diabetic retinopathy (DR). METHODS. This was a cross-sectional study of 379 patients (median age: 66.0 years) with diabetes attending a diabetes eye clinic. Daily fatty acid intake was assessed by using a validated Food Frequency Questionnaire and adjusted for energy intake. Diabetic retinopathy was graded from fundus photographs as no DR, nonproliferative DR, or proliferative DR. Patients were categorized as ‘‘well-controlled diabetes’’ (n = 123) and ‘‘poorly controlled diabetes’’ (n = 256), defined as glycated hemoglobin (HbA1c) level < 7.0% or ≥ 7.0%, respectively. RESULTS. There were no associations between any fatty acid intake and DR. However, among patients with well-controlled diabetes, increasing daily intake of PUFAs was associated with a reduced likelihood of the presence (odds ratio [OR]: 0.18; 95% confidence interval [CI]: 0.06– 0.59) and severity of DR after adjusting for age, sex, HbA1c, mean arterial blood pressure, and duration of diabetes. Moreover, an increased saturated fatty acid (SFA) intake was associated with increased likelihood of the presence (OR: 2.37; 95% CI: 1.15–4.88) and severity of DR. No association was found among those with poorly controlled diabetes. CONCLUSIONS. Increasing PUFA intake was associated with a reduced likelihood of the presence and severity of DR in well-controlled diabetes, whereas increasing SFA intake was associated with an increased likelihood of the presence and severity of DR. Further studies to confirm this observation are warranted to elucidate the underlying mechanisms and potential role of dietary PUFA and SFA intake in the management of DR. © 2015 The Association for Research in Vision and Ophthalmology, Inc.

We report a search for the charmless hadronic decay B0→ηπ0 with a data sample corresponding to an integrated luminosity of 694 fb-1 containing 753×106 BB¯ pairs. The data were collected by the Belle experiment running on the Y(4S) resonance at the KEKB e+e- collider. We measure a branching fraction B(B0→ηπ0)=(4.1-1.5-0.7+1.7+0.5)×10-7, where the first uncertainty is statistical and the second is systematic. Our measurement gives an upper limit of B(B0→ηπ0)<6.5×10-7 at 90% confidence level. The signal has a significance of 3.0 standard deviations and constitutes the first evidence for this decay mode. © 2015 American Physical Society. © 2015 American Physical Society.
