Although the influenza vaccine is effective in preventing influenza virus infection and its complications, it is not as effective in the elderly due to age-associated immunosenescence phenomenon. Since 2009, a high-dose trivalent influenza vaccine has been approved in the United States for the immunization of people ≥ 65 years with an antigen concentration four times higher than the standard vaccine. Multiple clinical trials carried out over different seasons, and using different methodologies, have shown that the high-dose trivalent influenza vaccine is not only more effective, but it also has a similar safety profile and is more immunogenic than the standard dose vaccine in the prevention of flu and its complications in the elderly. This document reviews the current scientific evidence on the safety and immunogenicity of high-dose influenza vaccine in people aged 65 years and over, and includes information from randomized clinical trials, observational studies with data from real clinical practice, and systematic reviews, and meta-analysis.To overcome the restricted degradation, poor antiacterial and osteoindctive problems of magnesium and its alloys, this study presented the spinning coating of an antimicrobial peptide (AP)-loaded silk fibroin (SF) composite onto a corrosion-resistant MgO-coated AZ31 Mg alloy via anodization (aMgO) and electrodeposition (eMgO) methods. The composite coatings not only created a smooth and hydrophilic surface, but also obviously improved the corrosion resistance according to the test of corrosion potential and current density. The colonization of E. coli on MgO-AP composite coatings was significantly reduced as compared to the MgO layers, due to the potential synergetic effects of APs and Mg2+. Compared with the bare AZ31, the composite coating inhibited the corrosion of the substrate and the release of Mg2+, supported the adhesion, spreading and proliferation of osteoblasts, and presented a significantly improved osteogenic differentiation trend. Therefore, the MgO-AP composite coating, which had both antibacterial and bone-promoting abilities, was expected to be applied for surface modification of magnesium alloy implants to solve the clinical problems of bacterial infection and poor osseointegration.Establishing standardized methods for a consistent analysis of spectral data remains a largely underexplored aspect in surface-enhanced Raman spectroscopy (SERS), particularly applied to biological and biomedical research. Here we propose an effective machine learning classification of protein species with closely resembled spectral profiles by a mixed data processing based on principal component analysis (PCA) applied to multipeak fitting on SERS spectra. This strategy simultaneously assures a successful discrimination of proteins and a thorough characterization of the chemostructural differences among them, ultimately opening up new routes for SERS evolution toward sensing applications and diagnostics of interest in life sciences.Formate dehydrogenase from Candida boidinii (CbFDH; EC.1.2.1.2) is a useful enzyme for CO2 reduction to formate in the photoredox system of a visible-light sensitizer and an electron mediator in the presence of an electron donor. BGJ398 research buy The electron mediator, cation radicals of 4,4'-bipyridinium salts (4,4'-BPs) act as the co-enzyme for CbFDH in the CO2 reduction to formate. We found that the CbFDH-catalyzed CO2 reduction to formate could be controlled by the ionic substituents introduced into the cation radical of 4,4'-BPs [Y. Amao, Sustainable Energy Fuels, 2018, 2, 1928-1950]. By using 1,1'-diaminoethyl-4,4'-bipyridinium salt (DABP), 1-aminoethyl-1'-methyl-4,4'-bipyridinium salt (AMBP), 1,1'-carboxymethyl-4,4'-bipyridinium salt (DCBP), and 1-carboxymethyl-1'-methyl-4,4'-bipyridinium salt (CMBP), the introduction of an amino-group into 4,4'-BP accelerates the CbFDH-catalyzed CO2 reduction to formate, while the introduction of a carboxy-group into 4,4'-BP slows the CO2 reduction to formate. This work clarified the direct interaction of the cation radicals of DABP, DCBP, AMBP, CMBP, and MV in the substrate-binding site of CbFDH by the docking simulation. In addition, a mechanistic investigation for the CbFDH-catalyzed CO2 reduction to formate with cation radicals of DABP, DCBP, AMBP, CMBP, and MV was carried out based on the energy of molecular orbitals calculated by density functional theory (DFT).We describe the rational development of a design for pleochroic molecular solids, by using C-Iπ halogen bonds to pre-organise different chromophores in a cocrystal. Using the structure of a known naphthalene cocrystal as a blueprint, we demonstrate how a highly robust C-Iπ motif permits the systematic exchange of original cocrystal components with azobenzene and azulene, resulting in optically interesting dichroic or pleochroic materials.Control of molecule adsorption and ordering on metal surfaces is of critical importance for the design and fabrication of molecule-based functional materials. In the present work, the molecule layer structures of coronene on Au(111) and HOPG are studied by combining scanning tunneling microscopy with image analysis techniques to unravel small changes in molecule adsorption geometry. Coronene forms a densely packed layer on Au(111) and HOPG at room temperature, but does not preferentially decorate the herringbone reconstruction. The molecule layer structure is confirmed by histograms of molecule radius and apparent height obtained from STM images using a python based open source code. Annealing at 116 °C initiates a tilting of coronene molecules on Au(111) by about 11 ± 4° which is deduced from statistical image analysis. The structural analysis is combined with an assessment of apparent height modulation with bias voltage to ascertain the reliability of the statistical analysis. Our work illustrates that the combination of advanced image analysis processing and STM images allows one to extract even small changes in a molecule layer structure.
