BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

OBJECTIVES: Successful outpatient colonoscopy (CLS) depends on many factors including the quality of a patient's bowel preparation. Although education on consumption of the pre-CLS purgative can improve bowel preparation quality, no study has evaluated dietary education alone. We have created an educational video on pre-CLS dietary instructions to determine whether dietary education would improve outpatient bowel preparation quality. METHODS: A prospective randomized, blinded, controlled study of patients undergoing outpatient CLS was performed...

Solar powered hydrogen evolution reaction (HER) is one of the key reactions in solar-to-chemical energy conversion. It is desirable to develop photocathodic materials that exhibit high activity toward photoelectrochemical (PEC) HER at more positive potentials because a higher potential means a lower overpotential for HER. In this work, the Cu2O/CuO bilayered composites were prepared by a facile method that involved an electrodeposition and a subsequent thermal oxidation. The resulting Cu2O/CuO bilayered composites exhibited a surprisingly high activity and good stability toward PEC HER, expecially at high potentials in alkaline solution...

The development of high efficiency catalysts for hydrogen evolution via water splitting has been an effective strategy to solve the energy environmental problems and energy crisis. The abundant-reserving transition-metals and their phosphides are becoming attractive Pt alternatives for hydrogen evolution reaction (HER). Herein, a crystalline/amorphous Co/CoP film was facilely prepared on nickel foam (NF) by one-step electrodeposition technique at room temperature, named as Co/CoP-NF. The as-prepared Co/CoP-NF electrocatalyst exhibits excellent electrocatalytic activity for HER, on par with Pt/C, showing a low overpotential of 35 mV at a current density of 10 mA cm-2 and small Tafel slope of 71 mV•dec-1 in 1...

The doubly acid-functionalised aniline PhN[(CH2)3B(C6F5)2]2 shows rapidly exchanging boron acid groups at the central base function and is an active frustrated Lewis pair due to cooperative hydride binding by both Lewis acids. Here we report investigations on the effect of different substituents at the central nitrogen atom and on the effect of exchanging nitrogen by phosphorus. Treatment of diallyl-tert-butylaniline with one equivalent of HB(C6F5)2 led to formation of a seven-membered iminium hydridoborate ring; after mono-hydroboration the intermediately formed frustrated Lewis pair reacts with the second allylamine function under ring closure...

The site-selective installation of lipid modifications on proteins is critically important in our understanding of how membrane association influences the biophysical properties of proteins as well as to study certain proteins in their native environment. Here, we describe the use of split inteins for the C-terminal attachment of lipid-modified peptides to virtually any protein of interest (POI) via protein trans-splicing (PTS). To achieve this, the protein of interest is expressed in fusion with the N-terminal split intein segment and the C-terminal split intein segment is prepared by solid phase peptide synthesis...

Cyclic peptides are highly desired molecules not only for basic research but also for many biomedical and pharmacological applications. Due to their potentially superior physicochemical properties as compared to their linear counterparts, they are considered as ideal candidates for studying protein-protein interactions, among others. Most of the methods developed in recent years to prepare cyclic peptides focus either on a synthetic or a recombinant route. While the former provides access to diversified, noncanonical peptides, including unnatural and D-amino acid, for example, the latter can harness the power of genetic randomization to generate and select from large peptide libraries...

A simple structure, efficient color splitting, sufficient output of electrical signals, and low power consumption are the important characteristics of contemporary devices for color sensing. In this study, we developed filter-free, junctionless structures that exhibited a superior photo-thermo-electrical response under a low bias voltage and a short response time in milliseconds. Although our compact sensor had a simple single-layer trench-like aluminum (Al) structure, it could perform multiple functions, including light harvesting, color-selective absorption, photo-thermo-electrical transformation, and the ability to collect photoinduced differences in electrical signals...

In this study, we developed the quaternized chitosan microgels without chemical crosslinking as an adjuvant of H5N1 split vaccine. The microgels with pH-sensitivity, positive surface charge and good biocompatibility, have been demonstrated in favor of enhancing both humoral and cellular immune response. However, the detailed mechanism of the chitosan-based microgels to enhance antigen specific immune responses remains unclear. Therefore, we prepared the quaternized chitosan microgels with well defined quaternization degrees (QDs, 20-80%) and particle sizes (800nm-5μm) by the premix membrane emulsification technique, and investigated the effect of quaternization degree (QD) and size on the adjuvanticity of microgels...
