Background High-pressure injection injuries are devastating injuries that often lead to an amputation of the primarily affected finger. The available literature mainly focuses on amputation rates, while there is a lack of knowledge regarding functional results. Patients and Methods Between 1998 and 2016, 47 cases of high-pressure injection injuries of the hand were registered in our department. Out of these, data of 26 patients, all men with an average age of 42 (18-62) years, were included in a retrospective follow-up examination after 4 (1-12) years...

Impairment of the autophagy pathway has been observed during the pathogenesis of Alzheimer's disease (AD), a neurodegenerative disorder characterized by abnormal deposition of extracellular and intracellular amyloid β (Aβ) peptides. Yet the role of autophagy in Aβ production and AD progression is complex. To study whether increased basal autophagy plays a beneficial role in Aβ clearance and cognitive improvement, we developed a novel genetic model to hyperactivate autophagy in vivo. We found that knock-in of a point mutation F121A in the essential autophagy gene Beclin 1/Becn1 in mice significantly reduces the interaction of BECN1 with its inhibitor BCL2, and thus leads to constitutively active autophagy even under non-autophagy-inducing conditions in multiple tissues, including brain...

The development of highly efficient and non-noble catalysts for both the reduction of 4-nitrophenol (4-NP) and NaBH4 hydrolysis is extraordinary attractive but it remains a tremendous challenge. In this work, self-assembled porous Co2P nanowires (NWs) have been successfully prepared via the low-temperature hydrothermal method and the comprehensive experiments validate that the sample is a high efficient bifunctional catalyst for both the reduction of 4-nitrophenol and sodium borohydride hydrolysis. Specifically, the as-prepared porous Co2P NWs exhibit more excellent catalytic performance (knor=743s(-1)g(-1)) than that of other reported catalysts towards reduction of 4-nitrophenol...

In the work, we have synthesized silver (Ag) nanoparticles deposited chitosan (CS) microcapsules with magnetic multiple Fe3O4 cores (denoted as Fe3O4/CS-Ag) as efficient catalysts for the reduction of 4-nitrophenol. The Fe3O4/CS-Ag catalysts are prepared by coating hydrophobic Fe3O4 nanoparticles with chitosan via a multiple emulsion-chemical crosslinking method and following in situ deposition of Ag nanoparticles onto the surfaces. The morphology and composition of the Fe3O4/CS-Ag microcapsules are characterized by Fourier transform infrared (FT-IR) spectra, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy...

Earthworms are the key soil organisms, contribute to many positive ecological services that could be degraded by pesticides and other soil pollutants such as heavy metals. Chemicals usually occur as mixtures in the environmental systems which can lead synergistic effects. The assessment and characterization of soil pollutants that effects risks are very difficult due to the complexity of soil matrix, poor understanding about the fate and effects of chemical combinations like pesticide and metal mixtures in terrestrial systems, and scarcity of toxicological data on mixtures of pollutants...

Caspase-3 is a key enzyme executing apoptosis during ontogenesis and homeostasis of multicellular organisms, and is a very important and potential drug target in treatment of apoptosis disturbance. So far, no commercial drugs for caspase-3 are available, and it is urgently necessitated to develop an effective method for caspase-3 activity assay and its inhibitor screening. In this paper, we propose a new method for determination of caspase-3 activity and its inhibition constant by combining single molecule fluorescence correlation spectroscopy (FCS) with a microwell chip...

Compared to natural enzymes, nanomaterial-based artificial enzymes have attracted immense attention because of their high stability and cost-effectiveness. In this study, cobalt nitride (Co4N) as a noble-metal-free artificial enzyme exhibiting highly intrinsic peroxidase-like activity and good stability was reported. Kinetic studies revealed that the resultant Co4N nanowires (NWs) exhibited a stronger affinity for 3,3',5,5'-tetramethylbenzidine (TMB) and H2O2 than HRP. Compared to Co3O4 NWs, Co4N NWs exhibited highly improved catalytic activities, with H2O2 exhibiting an apparent Km approximately 2 orders of magnitude less than that of Co3O4...

A novel series of donepezil-trolox hybrids were designed, synthesized and evaluated as multifunctional ligands against Alzheimer's disease (AD). Biological assays showed that these derivatives possessed moderate to good inhibitory activities against acetylcholinesterase (AChE) and monoamine oxidase B (MAO-B) as well as remarkable antioxidant effects. The optimal compound 6d exhibited balanced functions with good inhibition against hAChE (IC50 = 0.54 μM) and hMAO-B (IC50 = 4.3 μM), significant antioxidant activity (41...

In this study, we synthesized a novel perovskite nanomaterial consisting of AgBiO3 nanoparticles (NPs) via an ion-exchange method for remediation of polluted environments. The AgBiO3 NPs could self-produce significant amounts of reactive oxygen species (ROS) without light illumination or any other additional oxidant due to the controllable release of lattice oxygen from the crystalline AgBiO3, resulting in the formation of ROS somehow. The self-produced 1O2, O2•- and •OH were confirmed by electron spin resonance spectroscopy using a spin trap technique...

Microalgae offer great potential for biofuel production, but high photosynthetic activity is demanded for practical realization of microalgal biofuels. To this end, it is essential to evaluate the photosynthetic activity of single microalgal cells in a heterogeneous population. In this study, we present a method for monitoring photosynthetic activity of microalgae (in particular Euglena gracilis, a microalgal species of unicellular, photosynthetic, flagellate protists as our model organism) at single-cell resolution by Raman spectroscopy with deuterium from deuterium oxide (D2O) as a tracking probe...

Hypoxia plays an important role for the prognosis and therapy response of cancer. Thus, hypoxia imaging would be a valuable tool for pre-therapeutic assessment of tumor malignancy. However, there is no standard validated technique for clinical application available yet. Therefore, we performed a study in 12 patients with high-grade glioma, where we directly compared the two currently most promising techniques, namely the MR-based relative oxygen extraction fraction (MR-rOEF) and the PET hypoxia marker H-1-(3-[(18) F]-fluoro-2-hydroxypropyl)-2-nitroimidazole ([(18) F]-FMISO)...

Second harmonic generation (SHG) response is one of the most essential properties of nonlinear optical (NLO) materials. To achieve relatively strong SHG response, a feasible strategy is to introduce stereochemically active lone pair (SCALP) cations, such as Bi(3+). NLO materials with Bi(3+) usually exhibit a huge difference in SHG response, the inner correlation between the activity of SCALP and SHG response still being unclear owing to the lack of quantization estimation of the intensity of SCALP. Based on the calculation results of density functional theory (DFT), we develop a theoretical method to compute the intensity of the Bi-6s SCALP, which could describe the stereochemical behavior and exert significantly influences on some apparent optical properties, such as SHG response...
