7%) of included patients, respectively. Immediate clinical success was achieved in n=68 (89.5%), and procedural complications were observed in n=13 (17.1%) patients. Long-term follow-up revealed relapse of symptoms in n=21 (28.8%) patients, and overall survival estimates are 81.8%, 57.0% and 28.2% after two, five and ten years of follow-up, respectively. A trend towards longer relapse-free survival was found in the circumferential stenosis group (78.2% at five years) compared with the non-circumferential stenosis group (55.5%) (P=0.063). Conclusions Angioplasty and stenting of the SMA for CMI is relatively safe and effective despite a substantial number of patients experiencing clinical relapse over time. selleck chemicals Patients with focal, circumferential stenosis might have longer relapse-free survival than patients with non-circumferential stenosis.Aim Despite poorer health and healthcare outcomes experienced by lesbian, gay and bisexual adults, data for research to characterize and address these disparities remain limited. Patients & methods We describe sexual history information from 502,543 UK Biobank participants recruited between 2006 and 2010, as sexual identity was not collected from the cohort at baseline, and compare this with sexual history and sexual identity responses to the third National Survey of Sexual Attitudes and Lifestyles (NATSAL-3), collected between 2010 and 2012. Results After exclusions, 700 (0.3%) women and 2112 (1.2%) men in UK Biobank reported a history of exclusively same-sex sex and 5162 (2.3%) women and 4275 (2.3%) men reported a history of sex with both women and men; estimates were consistent with, although slightly lower those from NATSAL-3. Conclusion UK Biobank is an important resource for sexual minority health research.Brain metastases (BM) is common in non-small-cell lung cancer (NSCLC) patients. Immune checkpoint inhibitors (ICIs) have gradually become a routine treatment for NSCLC BM patients. Currently, three PD-1 inhibitors (pembrolizumab, nivolumab and cemiplimab), one PD-L1 inhibitor (atezolizumab) and one CTLA-4 inhibitor (ipilimumab) have been approved for the first-line treatment of metastatic NSCLC. It is still controversial whether PD-L1, tumor infiltrating lymphocytes, and tumor mutation burden can be used as predictive biomarkers for immune checkpoint inhibitors in NSCLC patients with BM. In addition, clinical data on NSCLC BM were inadequate. Here, we review the theoretical basis and clinical data for the application of ICIs in the therapy of NSCLC BM.Aim Two poly(ADP-ribose) polymerase (PARP) inhibitors olaparib and talazoparib are approved for patients with germline BRCA-mutated (gBRCAm) HER2-negative metastatic breast cancer. Methods A Bayesian fixed-effects indirect treatment comparison (ITC) analysis was performed to simulate the comparative efficacy (primary outcome of progression-free survival [PFS]) and safety of PARP inhibitor monotherapy. Results ITC of data from the OlympiAD (olaparib) and EMBRACA (talazoparib) studies suggested no significant difference in efficacy (PFS) between olaparib and talazoparib. However, there were differences in specific adverse events; patients receiving olaparib had a higher rate of nausea and vomiting, while those receiving talazoparib had a higher rate of alopecia and anemia. Discussion These data support the benefit of the PARP inhibitor class in gBRCAm HER2-negative metastatic breast cancer.We describe a general electrochemical method to functionalize donor-acceptor (D-A) cyclopropanes and -butanes with arenes utilizing Friedel-Crafts-type reactivity. The catalyst-free strategy relies on the direct anodic oxidation of the strained carbocycles, which leads after C(sp3)-C(sp3) cleavage to radical cations that act as electrophiles for the arylation reaction. Broad reaction scopes in regard to cyclopropanes, cyclobutanes, and aromatic reaction partners are presented. Additionally, a plausible electrolysis mechanism is proposed.The nearly commensurate charge density wave (CDW) excitations native to the transition-metal dichalcogenide crystal, 1T-TaS2, under ambient conditions are revealed by scanning tunneling microscopy (STM) and spectroscopy (STS) measurements of a graphene/TaS2 heterostructure. Surface potential measurements show that the graphene passivation layer prevents oxidation of the air-sensitive 1T-TaS2 surface. The graphene protective layer does not however interfere with probing the native electronic properties of 1T-TaS2 by STM/STS, which revealed that nearly commensurate CDW hosts an array of vortex-like topological defects. We find that these topological defects organize themselves to form a lattice with quasi-long-range order, analogous to the vortex Bragg glass in type-II superconductors but accessible in ambient conditions.We report structural and dynamical properties of liquid water described by the random phase approximation (RPA) correlation together with the exact exchange energy (EXX) within density functional theory. By utilizing thermostated ring polymer molecular dynamics, we examine the nuclear quantum effects and their temperature dependence. We circumvent the computational limitation of performing direct first-principles molecular dynamics simulation at this high level of electronic structure theory by adapting an artificial neural network model. We show that the EXX+RPA level of theory accurately describes liquid water in terms of both dynamical and structural properties.Band alignment effects of anatase and rutile nanocrystals in TiO2 powders lead to electron-hole separation, increasing the photocatalytic efficiency of these powders. While size effects and types of possible alignments have been extensively studied, the effect of interface geometries of bonded nanocrystal structures on the alignment is poorly understood. To allow conclusive studies of a vast variety of bonded systems in different orientations, we have developed a new density functional tight-binding parameter set to properly describe quantum confinement in nanocrystals. By applying this set, we found a quantitative influence of the interface structure on the band alignment.
