Background and Purpose: As a very common risk of adverse outcomes of the ischemic stroke patients, sarcopenia is associated with infectious complications and higher mortality. The goal of this retrospective study is to explore the predictive value of serum Cr/CysC ratio in acute ischemic stroke patients receiving nutritional intervention. Methods: We reviewed adult patients with AIS from December 2019 to February 2020. Patients with acute kidney injury were excluded and all patients received nutritional intervention during a 3-month follow-up period. We collected baseline data at admission including creatinine and cystatin C. The primary poor outcome was major disability (modified Rankin Scale score ≥ 4) at 3 months after AIS. Results: A total of 217 patients with AIS were identified for this study. Serum Cr/CysC ratio was significantly correlated with NIHSS at discharge, 1-month modified Rankin Scale score, and 3-month modified Rankin Scale score. During 3 months, 34 (15.70%) patients had a poor outcome after AIS and 11 (5.10%) patients died within 30 days. In multivariable logistic regression analyses, serum Cr/CysC ratio at admission was independently associated with 3-month poor outcomes (OR: 0.953, 95% CI: 0.921–0.986, p =.006) and 30-day mortality (OR: 0.953, 95% CI: 0.921–0.986, p =.006). Conclusion: As a blood biochemical indexes reflecting the muscle mass and aiding in risk stratification, Cr/CysC ratio at admission could be used as a predictor of 30-day mortality and long-term poor prognosis in AIS patients.

An efficient source of all-solid-state broadly tunable mid-infrared optical parametric oscillator based on a periodically poled MgO-doped lithium niobate is reported. The pump source is a 1064nm acousto-optically Q-switched diode-pumped Nd:YAG laser. A broadly tunable mid-infrared output from 1.56 to 1.67 µm were generated, with corresponding idler wavelengths of 3.34 to 2.93 µm by temperature tuning from 40 to 200°C. When the average pump power is 1.61 W with about 70 ns pulse duration operating at a repetition rate of 10 kHz, the maximum signal output power of the PPMgLN-OPO is about 211 mW at 1631 nm.

The thermodynamical behaviors of E′ centers in 8 quartz samples from core XJ33-2-1 recovered in the Zhujiang Mouth Basin were measured by electron spin resonance (ESR) technique. The E′ ESR spectral intensity of samples before any laboratory treatment was measured and expressed as I 1. The samples were then annealed at 300°C or 350°C for 60 min. The E′ ESR spectral intensity measured after this procedure is expressed as I 2. The ratios of I 1, to I 2 for the samples increase with the sample depth (from 320 to 3972 m), showing that there is a correlation between this ratio and the storage temperature of samples. Therefore the ratio of I 1/ I 2 can be used as an ESR paleothermometer. Besides the temperature, we must take into account the period of time for which the samples have been buried since their deposition, because we find that the ratios I 1/ I 2 (from 0.293 to 0.941) are closely related to the sediment ages (from 1.5 to 27.5 Ma), with a correlation coefficient of 0.98 or 0.99 obtained by linear or exponential regression, respectively. This relation can be explained by the increase of E′ center concentration in quartz samples with the sedimentation age. [ABSTRACT FROM AUTHOR]
