    To explore the relationship between the serum uric acid to creatinine (UA/Cr) ratio and the prevalence of hypertension. In this cross-sectional study, we included 8571 individuals from the China Health and Nutrition Survey. Logistic regression analysis and restricted cubic spline (RCS) were used to analyze the relationship between the UA/Cr ratio and hypertension. Compared with individuals without hypertension, individuals with hypertension had higher UA/Cr ratios. Multivariate logistic regression analysis showed that a higher UA/Cr ratio was closely related to a higher risk of hypertension (as a continuous variable, OR: 1.054, 95% CI: 1.014-1.095, p = 0.007; as a categorical variable, Q3 vs. Q1, OR: 1.183, 95% CI: 1.011-1.384, p = 0.035; Q4 vs. Q1, OR: 1.347, 95% CI: 1.146-1.582, p 2 (p p p p  The UA/Cr ratio was associated with the prevalence of hypertension.</p

    Cardiomyocyte Imaging Using <em>Real-Time</em> Spatial Light Interference Microscopy (SLIM)

    No full text
    <div><p>Spatial light interference microscopy (SLIM) is a highly sensitive quantitative phase imaging method, which is capable of unprecedented structure studies in biology and beyond. In addition to the π/2 shift introduced in phase contrast between the scattered and unscattered light from the sample, 4 phase shifts are generated in SLIM, by increments of π/2 using a reflective liquid crystal phase modulator (LCPM). As 4 phase shifted images are required to produce a quantitative phase image, the switching speed of the LCPM and the acquisition rate of the camera limit the acquisition rate and, thus, SLIM's applicability to highly dynamic samples. In this paper we present a fast SLIM setup which can image at a maximum rate of 50 frames per second and provide in real-time quantitative phase images at 50/4 = 12.5 frames per second. We use a fast LCPM for phase shifting and a fast scientific-grade complementary metal oxide semiconductor (sCMOS) camera (Andor) for imaging. We present the dispersion relation, i.e. decay rate vs. spatial mode, associated with dynamic beating cardiomyocyte cells from the quantitative phase images obtained with the real-time SLIM system.</p> </div

    All-solid-state lithium sulfide batteries exhibit great potential as next-generation energy storage devices due to their low cost and high energy density. However, the poor conductivity of the solid electrolytes and the low electronic conductivity of sulfur limit their development. In this work, the highly conductive Li7P3S11 glass-ceramic solid electrolyte with room temperature conductivity of 1.27 mS cm−1 is synthesized and combined with the FeS2 cathode and Li-In anode to fabricate FeS2/Li7P3S11/Li-In all-solid-state Li-S battery. The assembled battery delivers high initial discharge capacities of 620.8, 866.4 mAh g−1, and 364.8 mAh g−1 at 0.1C under room temperature, 60°C and 0°C, respectively. It shows a discharge capacity of 284.8 mAh g−1 with a capacity retention of 52.4% after 80 cycles at room temperature. When the operating temperature rises to 60°C, this battery suffers a fast decay of capacity in 40 cycles. However, this battery sustains a high discharge capacity of 256.6 mAh g−1 with a capacity retention of 87.9% after 100 cycles under 0°C, smaller volume expansion of ASSBs at 0°C keep the solid/solid contact between the electrolyte particles, thus resulting in better electrochemical performances. EIS and in situ pressure characterizations further verify that the differences of electrochemical performances are associated with the volume variations caused by the temperature effects. This work provides a guideline for designing all-solid-state Li-S which is workable in a wide temperature range.</p
