Objective To assess the safety of ocrelizumab (OCR) shorter duration infusion in patients with MS. Methods ENSEMBLE PLUS is a randomized, double-blind substudy to the single-arm ENSEMBLE study (NCT03085810). In ENSEMBLE, patients with early stage relapsing-remitting MS received OCR 600 mg initially as two 300 mg IV infusions 2 weeks apart and subsequently as a single 3.5-hour 600 mg infusion every 24 weeks for 192 weeks. In ENSEMBLE PLUS, OCR 600 mg administered over the approved 3.5-hour infusion time (conventional duration) is compared with a 2-hour infusion (shorter duration). The primary end point was the proportion of patients with infusion-related reactions (IRRs) after the first randomized dose (assessed during and up to 24 hours postinfusion). Results From November 1, 2018, to September 27, 2019, 580 patients were randomized 11 to the conventional or shorter infusion group. After the first randomized dose, 67 of 291 patients (23.1%) in the conventional and 71 of 289 patients (24.6%) in the shorter infntifier number NCT03085810.Objective Disease-modifying drugs (DMDs) may alter the immune status and thus increase the susceptibility to coronavirus disease 2019 (COVID-19) in patients with MS or neuromyelitis optica spectrum disorders (NMOSD). However, evidence supporting this notion is currently lacking. In this study, we conducted a survey on the risk of COVID-19 in patients with MS and NMOSD. Methods The survey was conducted through the Chinese Medical Network for Neuroinflammation. Patients in 10 MS centers from 8 cities including Wuhan were included. Information about MS and NMOSD disease duration and the usage of DMDs were collected. Data of suspected cases of COVID-19 were obtained from hospital visits, questionnaires, and patient self-reporting. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was confirmed through clinical evaluation by a panel of experts in conjunction with chest CT and viral RNA detection. Results Eight hundred eighty-two of 1,804 (48.89%) patients with MS and 2,129 of 3,060 (69.58%) patients with NMOSD were receiving DMDs. There were no alterations in the patients' DMD regimen during January 15, 2020, to March 15, 2020, the 3-month period. None of the patients with MS treated with DMDs had COVID-19. However, 2 patients with relapsing NMOSD were diagnosed with COVID-19-related pneumonia. After treatment, both patients recovered from pneumonia and neither patient experienced new attacks due to predisposing SARS-CoV-2 infection in the following 2 months. Conclusions No increased risk of COVID-19 infection was observed in patients with MS or NMOSD, irrespective of whether these patients received DMDs. A battery of stringent preventive measures adopted by neurologists to reduce COVID-19 infection in these patients may have contributed to low risk of COVID-19 infection.For many years, the lung disease associated with alpha-1 antitrypsin (AAT) deficiency (AATD) was perceived as being secondary to an imbalance between this serine protease inhibitor and the target protease, neutrophil elastase (NE). More recently, a greater understanding of the pathways leading to lung inflammation has shed light on new potential attributes and presented AATD as an inflammatory condition in which proteases and neutrophils still play a major role, but in which pro-inflammatory cytokines, either induced by the actions of NE or by other pro-inflammatory processes normally modulated by AAT, are involved. In this review, we will look at the various cytokines centrally involved in AATD lung disease, and how a greater understanding of their contribution may help development of targeted therapies.High entropy alloys (HEAs) holding several principal elements in high concentration represent unprecedented combination properties. Designing strong and well ductile HEAs has been attracting extensive attentions from researchers in the last decade, such as mechanisms in inducing different types of phases and nano-sized precipitates. Since some HEAs have low stacking fault energy, nano-twins prefer to form in plastic deformation process or magnetron sputtering, resulting in enhanced mechanical properties by the existence of twin boundaries, which implies that the addition of twin boundary in HEAs is a promising method in engineering HEAs. NDI-091143 mw Understanding how twin boundaries affect the mechanical properties of nano twinned HEAs is a key for designing strong and ductile nano twinned HEAs. In this study, we have performed large-scale molecular dynamic simulation to investigate the mechanical properties of HEAs with different twin boundary spacings at various temperatures. Results show that the strength of HEAs at atwinned HEAs.Understanding, optimizing, and controlling the optical absorption process, exciton gemination, and electron-hole separation and conduction in low dimensional systems is a fundamental problem in materials science. However, robust and efficient methods capable of modelling the optical absorbance of low dimensional macromolecular systems and providing physical insight into the processes involved have remained elusive. We employ a highly efficient linear combination of atomic orbitals (LCAOs) representation of the Kohn-Sham (KS) orbitals within time dependent density functional theory (TDDFT) in the reciprocal space (k) and frequency (ω) domains, as implemented within our LCAO-TDDFT-k-ωcode, applying either a priori or a posteriori the derivative discontinuity correction of the exchange functional ∆xto the KS eigenenergies as a scissors operator. In so doing we are able to provide a semi-quantitative description of the photoabsorption cross section, conductivity, and dielectric function for prototypical 0D, 1D, 2D, and 3D systems within the optical limit (||q|| → 0+) as compared to both available measurements and from solving the Bethe-Salpeter equation with quasiparticleG0W0eigenvalues (G0W0-BSE). Specifically, we consider 0D fullerene (C60), 1D metallic (10,0) and semiconducting (10,10) single-walled carbon nanotubes (SWCNTs), 2D graphene (Gr) and phosphorene (Pn),and 3D rutile (R-TiO2) and anatase (A-TiO2). For each system, we also employ the spatially and energetically resolved electron-hole spectral density to provide direct physical insight into the nature of their optical excitations. These results demonstrate the reliability, applicability, efficiency, and robustness of our LCAO-TDDFT-k-ωcode, and open the pathway to the computational design of macromolecular systems for optoelectronic, photovoltaic, and photocatalytic applicationsin silico.
