This systematic review and meta-analysis aimed to summarize the current clinical literature that investigates fracture healing in patients with diabetes. METHODS The outcome of interest was impaired fracture healing including non-union, delayed union and malunion. Studies that compared fracture healing outcomes between patients with and without diabetes were included in this study. Subgroup analyses regarding different fracture sites, types of fracture and classifications of diabetes were performed. RESULTS A total of 14 studies involving 695 patients with diabetes and 4937 controls fulfilled the inclusion criteria. Diabetes was associated with an increased risk of impaired fracture healing (odds ratio (OR) 2.11, 95% confidence interval (CI) 1.33-3.37, P = 0.002). Subgroup analyses showed that diabetes was associated with a significantly higher incidence of impaired fracture healing in lower extremity fractures (OR 2.63, 95% CI 1.30-5.30, P = 0.007), short bone fractures (OR 2.64, 95% CI 1.35-5.20, P = 0.005), long bone fractures (OR 2.13, 95% CI 1.23-3.70, P = 0.007) and osteoporosis-unrelated fractures (OR 2.39, 95% CI 1.19-4.80, P = 0.01). Both insulin-dependent diabetes (OR 4.04, 95% CI 1.05-15.56, P = 0.04) and non-insulin-dependent diabetes (OR 5.83, 95% CI 1.73-19.58, P = 0.004) were associated with significantly higher risks of impaired fracture healing. CONCLUSIONS Patients with diabetes have an increased risk of impaired fracture healing when compared to patients without diabetes. Fracture healing in the lower extremities, short bones and osteoporosis-unrelated fractures is affected more severely by diabetes. © 2020 Royal Australasian College of Surgeons.A new class of sky-blue- to green-emitting carbazolylgold(III) C^C^N complexes containing pyrazole or benzimidazole moieties has been successfully designed and synthesized. Through the judicious choice of the N-heterocycles in the cyclometalating ligand and the tailor-made carbazole moieties, maximum photoluminescence quantum yields of 0.52 and 0.39 have been realized in the green- and sky-blue-emitting complexes, respectively. Solution-processed and vacuum-deposited organic light-emitting devices (OLEDs) based on the benzimidazole-containing complexes have been prepared. The sky-blue-emitting device shows an emission peaking at 484 nm with a narrow full-width at half-maximum of 57 nm (2244 cm-1 ), demonstrating the potential of this class of complexes in the application of OLEDs with high color purity. In addition, high maximum external quantum efficiencies of 12.3 % and a long operational half-lifetime of over 5300 h at 100 cd m-2 have been achieved in the vacuum-deposited green-emitting devices. © 2020 Wiley-VCH Verlag GmbH & Co.

Since the morphology of a polymer chain is closely intertwined with its photophysical properties, it is desirable to be able to change the arrangement of the polymers at will. We investigate the π-conjugated polymer poly(9,9-dioctylfluorene) (PFO), which can exist in three distinctly different structural phases the α-, β-, and γ-phase. check details Every phase has a different chain structure and a unique photoluminescence (PL) spectrum. Due to its unique properties and the pronounced spectral structure-property relations, PFO can be used as a model system to study the morphology of π-conjugated polymers. To avoid ensemble averaging, we examine the PL spectrum of single PFO chains embedded in a non-fluorescent matrix. With single-molecule spectroscopy the structural phase of every single chain can be determined, and changes can be monitored very easily. To manipulate the morphology, solvent vapor annealing (SVA) was applied, which leads to a diffusion of the polymer chains in the matrix. The β- and γ-phases appear during the self-assembly of single α-phase PFO chains into mesoscopic aggregates. The extent of β- and γ-phase formation is directed by the solvent-swelling protocol used for aggregation. Aggregation unequivocally promotes formation of the more planar β- and γ-phases. Once these lower-energy more ordered structural phases are formed, SVA cannot return the polymer chain to the less ordered phase by aggregate swelling. © 2020 The Authors.

Inspired by the cryptobiotic state found in nature, cell-in-shell structures are formed, which are called artificial spores and which show suppression or retardation in cell growth and division and enhanced cell survival under harsh conditions. The property requirements of the shells suggested for realization of artificial spores, such as durability, permselectivity, degradability, and functionalizability, are demonstrated with various cytocompatible materials and processes. The first-generation shells in single-cell nanoencapsulation are passive in the operation mode, and do not biochemically regulate the cellular metabolism or activities. Recent advances indicate that the field has shifted further toward the formation of active shells. Such shells are intimately involved in the regulation and manipulation of biological processes. Not only endowing the cells with new properties that they do not possess in their native forms, active shells also regulate cellular metabolism and/or rewire biological pathways. Recent developments in shell formation for microbial and mammalian cells are discussed and an outlook on the field is given. © 2020 WILEY-VCH Verlag GmbH & Co.

NOP receptors are expressed in key neural substrates involved in pain and reward modulation. In nonhuman primates (NHPs), NOP receptor activation effectively exerts antinociception and anti-hypersensitivity at the spinal and supraspinal levels. Moreover, NOP receptor activation inhibits dopaminergic transmission and synergistically enhances mu-opioid peptide (MOP) receptor-mediated analgesia. In this article, we have discussed the functional profiles of ligands with dual NOP and MOP receptor agonist activities and highlight their optimal functional efficacy for pain relief and drug abuse treatment. Through coactivation of NOP and MOP receptors, bifunctional NOP/MOP receptor "partial" agonists (e.g., AT-121, BU08028, and BU10038) reveal a wider therapeutic window with fewer side effects. These newly developed ligands potently induce antinociception without MOP receptor agonist-associated side effects such as abuse potential, respiratory depression, itching sensation, and physical dependence.
