A combination of experimental and density functional theory (DFT) investigations suggests that the Cu-catalyzed fluorination of unsymmetrical diaryliodonium salts with general structure [Mes(Ar)I]+ in N,N'-dimethylformamide proceeds through a CuI/CuIII catalytic cycle. A low concentration of fluoride relative to combined iodonium reagent plus copper ensures that [Mes(Ar)I]+ is available as the ...

صخلملا Infertility affects 15% of couples seeking children worldwide and male factor is evident in about 30-50% of the cases. To assess the effect of sperm chromatin integrity on the outcomes of intracytoplasmic injection, sperm DNA compactness was evaluated by acridine orange staining in 40 fertile and 44 infertile men attending one infertility clinic. The results showed no significant differe...

صخلملا The search for novel anticancer drugs continues. This work includes a preliminary study of the effect of two crude extracts of Greek or Mediterranean sage (Salvia triloba L. f.) on three malignant human cell lines and one malignant murine cell line. A boiling water extract and a methanolic extract were prepared from dried leaves of S. triloba. Yields of extraction were 9.8 and 22.4%, res...

INTRODUCTION This study compared canal and isthmus debridement efficacies between side-vented needle irrigation (SNI) and continuous ultrasonic irrigation (CUI) in the mesial root of mandibular first molars with narrow isthmuses using a closed-canal design. METHODS Micro-computed tomography scanning was used to select 20 teeth, each containing a narrow isthmus. Each root was sealed at the ape...

In a recent letter, Cui, Duan and Chan propose a generalisation of the Scott-Barreto method to build a larger family of MNT curves, and they claim that their proposal is also applicable to other curve construction methods. Here we show that the Cui-Duan-Chan technique is irrecoverably flawed.
