Green and sustainable applications of energetic plasmon-activated water
Chih-Ping Yang,Shih-Hao Yu,Yu-Chuan Liu 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.111 No.-
This review describes the use of bulk deionized water (DIW) treatment to become plasmon-activatedwater (PAW) with reduced hydrogen bonds (HBs). PAW with special properties can be used in innovativeapplications and development of environmental protection science and sustainable energy management. PAW is a natural water solvent, but PAW subverts the public’s idea that hydrophobic solutes are difficultto dissolve in water. PAW can dissolve more-hydrophobic solutes than ordinary water, and can also interactwith water-soluble alcohol molecules to form stronger HBs. Moreover, in the application of certainreduction reactions, no chemical reducing agent is needed, and the catalytic reduction effect can beachieved using natural PAW. A characteristic application of PAW can also be extended to seawater desalination. Due to weak HBs among PAW molecules, high water evaporation rates can be produced, and ahigher chemical potential can also be applied to the innovative development of solar energy storage. In electrochemical applications, PAW itself can promote water oxidation, oxygen reduction reactions,hydrogen and oxygen evolution reactions, and the efficient capacitor production of H2O2. Furthermore,PAW can delay the melting of sea ice in the habitat of polar bears, so it may be applied to the issue ofsaving polar bears.

This study evaluated the value of procalcitonin (PCT) levels in pleural effusion to differentiate the etiology of parapneumonic effusion (PPE). Forty-one consecutive PPE patients were enrolled and were divided into bacterial and non-bacterial PPE. Blood and pleural effusion samples were collected for PCT measurement on admission and analyzed for diagnostic evaluation. PCT of pleural fluid was significantly increased in the bacterial PPE group (0.24 ng/mL) compared to the non-bacterial PPE group (0.09 ng/mL), but there was no significant difference for serum PCT. A PCT concentration of pleural fluid >0.174 ng/mL (best cut-off value) was considered positive for a diagnosis of bacterial PPE (sensitivity, 80%; specificity, 76%; AUC, 0.84). Pleural effusion PCT in the bacterial PPE is significantly different from those of the non-bacterial PPE and control groups, so the diagnostic use of PCT still warrants further investigation.

Advanced Imaging of Nanometer-Scale Recorded Bits on Super-Resolution Near-Field Optical Disk
Pei Lin Yang,Din Ping Tsai,Cheng Wei Lin,Chih Ching Hsu,Pei Hsin Chang,Tsung Sheng Kao,Wei Chih Lin 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.47 No.1
An advanced imaging technique is demonstrated for fast, non-destructive and high resolution characterizations for nanometer-scale recorded bits on a super-resolution near-field optical disk (super-RENS). For the first time, an array of individual 100 nm recorded marks is imaged and studied by using the conductive-atomic force microscopy (C-AFM) method. Discussions also include comparisons of 300 nm, 200 nm and 100 nm recorded marks on both a super-RENS disk and a commercial DVD disk, and the image results are evidence of the high carrier-to-noise ratio (CNR) value on the super-RENS disk, even though the mark size has been shrunk to less than the diffraction limit.

Objective To systematically examine the effectiveness and tolerability of psilocybin for treating end-of-life anxiety symptoms. Methods The Medline, Embase, CENTRAL, and PsycINFO databases were searched up to November 25, 2020. We enrolled clinical trials investigating psilocybin for treating end-of-life anxiety symptoms. Meta-analysis was conducted using random-effects model. Results Overall, five studies were included, revealing that psilocybin was superior to the placebo in treating state anxiety at 1 day (Hedges’ g, -0.70; 95% confidence interval, -1.01 to -0.39) and 2 weeks (-1.03; -1.47 to -0.60) after treatment. Psilocybin was more effective than placebo in treating trait anxiety at 1 day (-0.71; -1.15 to -0.26), 2 weeks (-1.08; -1.80 to -0.36), and 6 months (-0.84; -1.37 to -0.30) after treatment. Psilocybin was associated with transient elevation in systolic (19.00; 13.58-24.41 mm Hg) and diastolic (8.66; 5.18-12.15 mm Hg) blood pressure compared with placebo. The differences between psilocybin and placebo groups with regard to allcause discontinuation, serious adverse events, and heart rates were nonsignificant. Conclusion Psilocybin-assisted therapy could ameliorate end-of-life anxiety symptoms without serious adverse events. Because of the small sample sizes of the included studies and high heterogeneity on long-term outcomes, future randomized controlled trials with large sample sizes are needed.

Objective Individuals with dementia are at a substantially elevated risk for mortality; however, few studies have examined multimorbidity patterns and determined the inter-relationship between these comorbidities in predicting mortality risk.Methods This is a prospective cohort study. Data from 6,556 patients who were diagnosed with dementia between 1997 and 2012 using the Taiwan National Health Insurance Research Database were analyzed. Latent class analysis was performed using 16 common chronic conditions to identify mortality risk among potentially different latent classes. Logistic regression was performed to determine the adjusted association of the determined latent classes with the 5-year mortality rate.Results With adjustment for age, a three-class model was identified, with 42.7% of participants classified as “low comorbidity class (cluster 1)”, 44.2% as “cardiometabolic multimorbidity class (cluster 2)”, and 13.1% as “FRINGED class (cluster 3, characterized by FRacture, Infection, NasoGastric feeding, and bleEDing over upper gastrointestinal tract).” The incidence of 5-year mortality was 17.6% in cluster 1, 26.7% in cluster 2, and 59.6% in cluster 3. Compared with cluster 1, the odds ratio for mortality was 9.828 (95% confidence interval [CI]=6.708–14.401; p<0.001) in cluster 2 and 1.582 (95% CI=1.281–1.953; p<0.001) in cluster 3.Conclusion Among patients with dementia, the risk for 5-year mortality was highest in the subpopulation characterized by fracture, urinary and pulmonary infection, upper gastrointestinal bleeding, and nasogastric intubation, rather than cancer or cardiometabolic comorbidities. These findings may improve decision-making and advance care planning for patients with dementia.
