N-Heterocyclic carbenes (NHCs) were functionalized with a triisopropylsilyl (TIPS)-protected alkyne group and self-assembled on Au films to enable post-deposition functionalization by C-C coupling reactions. The TIPS group efficiently protected the alkyne and prevented its deprotonation during surface-anchoring of NHC. Sonogashira C-C coupling…[Read more]

rectors are common, although large variation exists between specialties. The majority of direct payments to residency program directors are for non-research related activities.In this article, the authors briefly review the history and status of institutional honor wall portraits at medical schools, and they highlight the implications of a lack of…[Read more]

Bioassay-guided fractionation of the organic extracts of the endophyte Daldinia eschscholtzii strain GsE13 led to the isolation of several phytotoxic compounds, including two chromenone and two chromanone derivatives 5-hydroxy-8-methoxy-2-methyl-4H-chromen-4-one, 1; 5-hydroxy-2-methyl-4H-chromen-4-one, 2; 5-methoxy-2-methyl-chroman-4-one, 3; and…[Read more]

In most of the final results, the average total errors between the reconstructed 3D surface and the CAD geometry are less than 0.1 mm.A new method for profile measurements of small transverse size beams by means of a vibrating wire is presented. A vibrating wire resonator with a new magnetic system was developed and manufactured to ensure that the…[Read more]

Several observational studies have compared the effectiveness and safety outcomes between nonvitamin K antagonist oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) in atrial fibrillation (AF) patients with a history of either stroke/transient ischemic attack (TIA) or intracranial hemorrhage. Therefore, our current meta-analysis aimed to…[Read more]

Disturbances in the AD of pvNAWM, CB, and CC, associated with axonal damage, are a predominant factor in the development of CI in CSVD. The relationship between AD predictors and both blood flow and CSF flow indicates a disturbance in their relationship, while their location near the floor of the lateral ventricle and their link with indicators of…[Read more]
