Palladium-catalyzed direct C-H functionalization of benzoquinone

A direct Pd-catalyzed C=H functionalization of benzoquinone (BQ) can be controlled to give either mono- or disubstituted BQ, including the installation of two different groups in a one-pot procedure. BQ can now be directly functionalized with aryl, heteroaryl, cycloalkyl, and cycloalkene groups and, moreover, the reaction is conducted in environmentally benign water or acetone as solvents

Severe dysphagia after a posterior cervical spine fusion at the C1–C3 level and its improvement after correction surgery for malalignment: a case report

Abstract Background The development of dysphagia and trismus following posterior C1–C3 fusion is rare compared to occipitocervical fusion, and there are very few reports in the literature. Case presentation A 75-year-old Thai man who had an extradural tumor at the C1/C2 level developed severe dysphagia and trismus immediately after tumor resection and C1–C3 fusion. During the surgery for malalignment correction, the C1–C2 screws were re-aligned into an increased lordotic position. The symptoms resolved immediately post-surgery. Conclusions Short upper cervical fusion can produce trismus and dysphagia in a relatively flexed position. Preoperative planning should be individualized based on the patient’s resting neutral alignment to prevent complications

Structural equation modeling of a potentially successful person in network marketing

This study developed a structural equation model to explain the attributes of a potentially successful person in network marketing. The researcher collected data on 400 network marketers, from 10 companies, who had been in business seriously for at least 2 years. The results showed that a potentially successful person in network marketing exhibitted four latent variables: 1) unsatisfied valued life-desire discrepancy 2) effectiveness of choice in closing the gap on discrepancies 3) Phalanuphap—power to move people, and 4) assertiveness when significant others have become an obstacle. There is a causal relationship between these latent variables and success in network marketing, and the structural equation modeling of potentially successful persons in network marketing which was developed in this study fits well with the empirical data
