Direct hydroxylation of a wide scope of aryl halides was catalyzed by a combination of CuI and lithium pipecolinate in water with yields up to 92%.

We obtain the equivalence of the properties (β) and (NUC) in Orlicz function spaces. This answers a question raised by Y. Cui, R. Pluciennik and T. Wang.

Hepatocellular carcinoma (HCC) is a highly lethal disease, and surgical resection one of the major treatment methods used. However, to date, at least best our knowledge, there no effective prognostic scoring system for overall survival (OS) relapse‑free (RFS) patients following hepatectomy. The present study developed low‑cost easy‑to‑use model based on clinicopathological characteristics with ...

BACKGROUND The efficacy of endodontic irrigation procedures can be compromised by the complexity of the root canal system. Delivering irrigants to the apical third of curved canals presents a particular challenge to endodontists. This study compared the effects of two ultrasonic irrigation techniques on the penetration of sodium hypochlorite into the main canal and simulated lateral canals of c...
