PURPOSE To compare gadolinium retention in the abdominal organs after administration of gadoxetic acid disodium, a liver-specific contrast agent, compared to gadodiamide and gadobutrol. METHODS Three types of gadolinium-based contrast agents (GBCAs) were administered to rats. A single (gadodiamide and gadobutrol, 0.1 mmol/kg; gadoxetic acid disodium, 0.025 mmol/kg) or double label-recommended dose was intravenously administered once (Group 1), a single dose was administered 4 times (Group 2) and a single dose with or without a chelating agent (intraperitoneal injection immediately after each GBCA administration) was administered (Group 3). Rats were sacrificed after 1, 4, and 12 weeks and gadolinium concentrations in the liver, spleen, kidney, muscle, and bone were measured by inductively coupled plasma mass spectrometry. P values less than 0.05 were considered statistically significant. Liproxstatin1 RESULTS More gadolinium was retained with a double dose compared to a single dose, but there was no observed significant difference in gadolinium retention after a double dose compared to a single dose (P > .05). Gadodiamide was retained the most in all tissues followed by gadobutrol and gadoxetic acid disodium. Residual gadolinium was significantly less at 4 weeks compared to 1 week (P .05). CONCLUSION Gadolinium was retained the least in abdominal organs after gadoxetic acid disodium was administered and most of the residual gadolinium was excreted 4 weeks after GBCA administration when a label-recommended dose was administered. A commercially available chelation therapy agent could not reduce gadolinium retention. © 2020 International Society for Magnetic Resonance in Medicine.In vitro selected ribozymes are promising tools for site-specific labeling of RNA. Previously known nucleic acid catalysts attached fluorescently labeled adenosine or guanosine derivatives via 2',5'-branched phosphodiester bonds to the RNA of interest. Here we report new ribozymes that use orthogonal substrates, derived from the antiviral drug tenofovir, and attach bioorthogonal functional groups, as well as affinity handles and fluorescent reporter units via a hydrolytically more stable phosphonate ester linkage. The tenofovir transferase ribozymes were identified by in vitro selection and are orthogonal to nucleotide transferase ribozymes. As genetically encodable functional RNAs, these ribozymes may be developed for potential cellular applications. Here, the orthogonal ribozymes addressed desired target sites in large RNAs in vitro , as shown by fluorescent labeling of E.coli 16S and 23S rRNAs in total cellular RNA. © 2020 WILEY-VCH Verlag GmbH & Co.

Layered compounds serve as precursors for atomically thin 2D materials (briefly, 2D nanomaterials) owing to their strong intraplane chemical bonding but weak interplane van der Waals interactions. There are newly emerging 2D materials beyond graphene, and it is becoming increasingly important to develop cost-effective, scalable methods for producing 2D nanomaterials with controlled microstructures and properties. The variety of developed synthetic techniques can be categorized into two classes bottom-up and top-down approaches. Of top-down approaches, the exfoliation of bulk 2D materials into single or few layers is the most common. This review highlights chemical and physical exfoliation methods that allow for the production of 2D nanomaterials in large quantities. In addition, remarkable examples of utilizing exfoliated 2D nanomaterials in energy and environmental applications are introduced. © 2020 WILEY-VCH Verlag GmbH & Co.

However, this benefit may be accompanied by an unintended negative consequence in the form of greater overall alcohol consumption due to increased availability of affordable and convenient transport. AIMS To assess (i) the extent to which drinkers may choose to use AVs after consuming alcohol; (ii) the extent to which drinkers may consume more alcohol if they are using an AV afterwards; and (iii) whether demographic, alcohol-related and AV-related factors are associated with the likelihood of engaging in these behaviours. DESIGN AND METHODS A total of 1334 Australians of legal driving age who consume alcohol completed an online survey. Two regression models were used to calculate whether the analysed respondent characteristics were associated with intentions to use AVs after drinking and to consume more alcohol if using an AV afterwards. RESULTS Around half of the respondents (49%) reported being likely to use an AV after consuming alcohol, and over one-third (37%) reported being likely to consume more alcohol if using an AV afterwards. Younger age, more frequent alcohol consumption, a positive attitude to AVs and a preference for using 'ride-share' AVs were associated with a greater likelihood of engaging in these behaviours. DISCUSSION AND CONCLUSIONS The results suggest that the introduction of AVs is likely to reduce drink-driving rates while facilitating greater participation in heavy episodic drinking. This will constitute a challenge to policymakers in their efforts to minimise alcohol-related harms. © 2020 Australasian Professional Society on Alcohol and other Drugs.INTRODUCTION Complex regional pain syndrome (CRPS) can be effectively treated with spinal cord stimulation (t-SCS). There is also evidence that dorsal root ganglion (DRG) stimulation may be superior to t-SCS in CRPS. However, there has been no published data, to our knowledge, that looked at the concurrent use of t-SCS and DRG stimulation for treatment of CRPS. METHODS Our study includes four patients with severe CRPS who had all been implanted with a t-SCS. While all these patients had positive results from their t-SCS, they all had areas which lacked coverage, giving them incomplete pain relief. These patients also underwent successful trial and implantation of DRG-S. All four patients reported further improvement in their residual pain and function with DRG-S (>60%), and even superior pain relief (>80%) with concurrent use of t-SCS and t-SCS. RESULTS All patients had a diagnosis of lower extremity CRPS-1. After DRG-S implantation, multiple attempts were made in each patient to use DRG-S alone by temporarily turning the t-SCS off.
