Heart rate, oxygen saturation, and the baby's facial expression were recorded by a camera 3 min before the intervention, during the sampling, and 3 min after the procedure. After collecting the data, the head researcher and the assistant researcher separately watched the videos and scored them by using the Premature Infant Pain Profile-Revised (PIPP-R). Outcome measures The difference of pain scores (PIIP-R) between two groups. Results There was a statistically significant difference between the two groups in terms of PIPP-R scores during and after the sampling (p = 0.008 and p = 0.03 respectively). The PIPP-R scores at the beginning of the procedure were not found to be significantly different between the groups (p > 0.05). Conclusions Inhalation of lavender scent is effective in pain control in premature infants. It is safe and low cost; it does not interfere with medical care.

Based on our previous pilot study, systemic inflammatory response syndrome is more common in off-pump compared to on-pump coronary artery bypass. Therefore, we conducted a clinical trial of dexamethasone in patients undergoing off-pump coronary artery bypass.

Sixty consecutive patients undergoing off-pump coronary artery bypass were enrolled from August 2018 to January 2019 and randomized to a dexamethasone or placebo group of 30 each. Clinical outcomes were analyzed.

There was a lower incidence of major adverse cardiac events in the dexamethasone group compared to the placebo group (17% versus 43%,

 = 0.024). Clinical outcomes in the dexamethasone group were better than those in the placebo group, in terms of duration of mechanical ventilation (

 = 0.029), intensive care unit stay (

 = 0.028), hospital stay (

 = 0.04), and vasoactive-inotropic score (

 = 0.045). There were significant differences in inflammatory markers between the two groups interleukin-6 (

 = 0.0001), procalcitonin (

 = 0.0001), and C-reactive protein (

 = 0.0001) were lower in the dexamethasone group. There was a significant association between the incidence of major adverse cardiac events and both interleukin-6 (

 = 0.005) and procalcitonin (

 = 0.007).

Preoperative dexamethasone in patients undergoing off-pump coronary artery bypass is effective in improving clinical outcomes and controlling the postoperative inflammatory reaction.

Therefore, reducing the incidence and mortality of CRC is still a worldwide concern. This study aims to explore the clinical significance of lactamase beta (LACTB)-like expression in CRC tissues. Materials and Methods The expression of LACTB in CRC tissues and adjacent tissues in The Cancer Genome Atlas database was analyzed and the analysis results were verified by immunohistochemistry. The correlation between the expression level of LACTB and pathological factors and prognosis was analyzed. Results There was statistical difference in the expression of LACTB in CRC tissues and adjacent tissues (p  less then  0.01). The expression of LACTB in CRC tissues was correlated with clinical stage (p  less then  0.01). The expression of LACTB in CRC patients with lymph node metastasis was significantly lower than that in CRC patients without lymph node metastasis (p  less then  0.01). Low expression of LACTB contributed to the poor prognosis of CRC patients. The 5-year survival rate of CRC patients with low LACTB expression was significantly lower than that of CRC patients with high LACTB expression (p = 0.010, p = 0.047). Conclusions The expression of LACTB in CRC tissues was significantly lower than that in normal tissues, and it was significantly correlated with clinical prognosis, suggesting that LACTB could inhibit the CRC invasion and metastasis. This indicated to some extent that LACTB could be used as a prognostic marker and a new therapeutic target for CRC.Recently, a deep learning-based enhancing Position-Specific Scoring Matrix (PSSM) method (Bagging Multiple Sequence Alignment [MSA] Learning) Guo et al. has been proposed, and its effectiveness has been empirically proved. Aristolochic acid A molecular weight Program EPTool is the implementation of Bagging MSA Learning, which provides a complete training and evaluation workflow for the enhancing PSSM model. It is capable of handling different input data set and various computing algorithms to train the enhancing model, then eventually improve the PSSM quality for those proteins with insufficient homologous sequences. In addition, EPTool equips several convenient applications, such as PSSM features calculator, and PSSM features visualization. In this article, we propose designed EPTool and briefly introduce its functionalities and applications. The detailed accessible instructions are also provided.Gold nanowires (AuNWs) possess strong potential application in micro- and nanoelectronics as well as in plasmonic waveguides because of their low electrical resistance. However, the synthesis of pure solvent-dispersible AuNWs with full control over their length still remains a challenge. All the previously reported methods produce AuNWs with other impurities such as smaller nanorods, platelets, and spherical particles and are limited to a certain length (typically below 10 μm). This article describes a one-step synthesis of extremely long AuNWs (up to 25 μm) with great control over their dimensions by using pentahedrally twinned gold nanorods (AuNRs) as seed particles. To induce the AuNW growth, the reduction of Au(I) to Au(0) was carried out on the surface of AuNRs at a very low pH by introducing HCl into the growth solution. The slow conversion of Au(I) to Au(0) due to the increase in reduction potential at lower pH promoted the preferential deposition of metallic gold on the more reactive tips of AuNRs compared to their sides, resulting in the formation of AuNWs. In analogy to the "living" polymerization reaction, the length of the AuNWs was proportional to the amount of Au(I) added to the growth solution; thus, the desired length of AuNWs was achieved by controlling the supply of Au(I) ions in the reaction mixture. The AuNWs longer than 6 μm were found to be responsive to microwave radiation. When an aqueous solution of AuNWs was exposed to microwaves, the formation of sharp kinks was observed in several locations of AuNWs without their disintegration into smaller pieces.A user-friendly approach is presented to sidestep the venerable Grignard addition to unactivated ketones to access tertiary alcohols by reversing the polarity of the disconnection. In this work a ketone instead acts as a nucleophile when adding to simple unactivated olefins to accomplish the same overall transformation. The scope of this coupling is broad as enabled using an electrochemical approach, and the reaction is scalable, chemoselective, and requires no precaution to exclude air or water. Multiple applications demonstrate the simplifying nature of the reaction on multistep synthesis, and mechanistic studies point to an intuitive mechanism reminiscent of other chemical reductants such as SmI2 (which cannot accomplish the same reaction).Ionizable residues are rarely present in the hydrophobic interior of proteins, but when they are, they play important roles in biological processes such as energy transduction and enzyme catalysis. Internal ionizable residues have anomalous experimental pKa values with respect to their pKa in bulk water. This work investigates the atomistic cause of the highly shifted pKa of the internal Glu23 in the artificially mutated variant V23E of Staphylococcal Nuclease (SNase) using pH replica exchange molecular dynamics (pH-REMD) simulations. The pKa of Glu23 obtained from our calculations is 6.55, which is elevated with respect to the glutamate pKa of 4.40 in bulk water. The calculated value is close to the experimental pKa of 7.10. Our simulations show that the highly shifted pKa of Glu23 is the product of a pH-dependent conformational change, which has been observed experimentally and also seen in our simulations. We carry out an analysis of this pH-dependent conformational change in response to the protonation state change of Glu23. Using a four-state thermodynamic model, we estimate the two conformation-specific pKa values of Glu23 and describe the coupling between the conformational and ionization equilibria.Si has been extensively investigated as an anode material for lithium-ion batteries because of its superior theoretical capacity. However, a scalable fabrication method for a Si-based anode with high initial coulombic efficiency (ICE) and large volumetric capacity remains a critical challenge. Herein, we proposed a novel porous Si/Cu anode in which planar Si islands were embedded in the porous Cu matrix through combined laser additive manufacturing and chemical dealloying. The compositions and dimensions of the structure were controlled by metallurgical and chemical reactions during comprehensive interaction. Such a structure has the advantages of micro-sized Si and porous architecture. The planar Si islands decreased the surface area and thus increased ICE. The porous Cu matrix, which acted as both an adhesive-free binder and a conductive network, provided enough access for electrolyte and accommodated volume expansion. The anode structure was well maintained without observable mechanical damage after cycling, demonstrating the high structure stability and integrity. The porous Si/Cu anode showed a high ICE of 93.4% and an initial volumetric capacity of 2131 mAh cm-3, which retained 1697 mAh cm-3 after 100 cycles at 0.20 mA cm-2. Furthermore, the full-cell configuration (porous Si/Cu //LiFePO4) exhibited a high energy density of 464.9 Wh kg-1 and a capacity retention of 84.2% after 100 cycles.We investigated the polymer chain dynamics in a 2-3 nm thick poly(vinyl acetate) (PVAc) adsorption layer on a Si substrate with a native oxide layer via neutron reflectometry combined with toluene vapor-induced swelling. We can investigate the polymer chain dynamics difference in the film thickness direction by the difference in the degree of swelling of the polymer layers detected by neutron reflectometry. The mobility of the polymer chains depends on the distance from the substrate. The results elucidated that the interfacial layer with a thickness of approximately 1 nm did not swell at all with toluene vapor, which is a solvent for PVAc. Meanwhile, the surface layer excessively swells with toluene vapor compared to the bulk. This indicates that the polymer chain within the interfacial region is immobilized by the substrate through hydrogen-bonding interaction, but in the surface region, the surface effect overcomes this interfacial interaction. We concluded that the polymer chains in the adsorption layer are either strongly constrained to the substrate, owing to hydrogen bonding, or more mobile than the bulk, owing to the surface effect.
