One-step green synthetic approach for the preparation of multicolor emitting copper nanoclusters and their applications in chemical species sensing and bioimaging.

One-step green microwave synthetic approach was developed for the synthesis of copper nanoclusters (Cu NCs) and used as a fluorescent probe for the sensitive detection of thiram and paraquat in water and food samples. Unexpectedly, the prepared Cu NCs exhibited strong orange fluorescence and showed emission peak at 600 nm, respectively. Under optimized conditions, the quenching of Cu NCs emission peak at 600 nm was linearly proportional to thiram and paraquat concentrations in the ranges from 0.

Synthesis and antiproliferative activity of novel α-aminophosphonates.

A novel series of carbazole-based α-aminophosphonates were synthesized by three component coupling of 6-bromo-9-ethyl-9H-carbazole-3-carbaldehyde, amine and diethyl phosphite using polyethylene glycol (PEG-400) as a green reaction media. The antiproliferative activity of these molecules was evaluated against three cancer cell lines. Of these, compounds 4c, 4e and 4m were found to exhibit good antiproliferative activity against three cancer cells, A549, MCF-7, and NCI-N87.

Anti-CD40L monoclonal antibody treatment induces long-term, tissue-specific, immunologic hyporesponsiveness to peripheral nerve allografts.

The CD40/CD40L costimulatory pathway plays a crucial role in allograft rejection. The purpose of this study was to determine the effectiveness of anti-CD40L monoclonal antibody (mAb) treatment as a method to induce long-term, tissue-specific, immunologic hyporesponsiveness to peripheral nerve allografts. Sciatic nerve allografts were performed from BALB/c donor mice into C57BL/6 recipients.

Peripheral nerve transplantation: the role of chemical acellularization in eliminating allograft antigenicity.

This study tests the hypothesis that a chemically acellularized peripheral nerve allograft is as immunologically inactive as a peripheral nerve isograft. Cellular and acellular sciatic nerves were transplanted from BALB/c into C57BL/6 mice. C57BL/6 sciatic nerves were also transplanted into C57BL/6 recipients as isograft controls.

Effects of vascular endothelial growth factor on nerve regeneration in acellular nerve grafts.

The purpose of this study was to evaluate the effects of human recombinant vascular endothelial growth factor (VEGF-165) on peripheral nerve axonal sprouting and elongation following peripheral nerve injury and repair. Two-centimeter nerve gaps were created in rat peroneal nerves and repaired with either peripheral nerve autografts, acellular peripheral nerve isografts, or VEGF-165-treated acellular peripheral nerve isografts. Four months postoperatively, the peroneal nerves were harvested and histomorphometric analysis was performed.

Modified technique for nipple-areolar reconstruction: a case series.

Thousands of women undergo postmastectomy breast reconstruction each year. Part of the reconstruction of an aesthetically pleasing breast is a high-quality nipple-areolar reconstruction. The goals for this reconstruction include appropriate nipple projection, areolar color, and areolar texture.
