KGaA, Weinheim.OBJECTIVE To synthesize the literature on the views and experiences of patients/family members and health-care professionals (HCPs) on the disclosure of adverse events. METHODS Systematic review of qualitative studies. Apocynin research buy Searches were conducted in MEDLINE, Embase, PubMed, CINAHL and PsycINFO. Study quality was evaluated using the Critical Appraisal Skills Programme tool. Qualitative data were analysed using a meta-ethnographic approach, comprising reciprocal syntheses of 'patient' and 'health-care professional' studies, combined to form a lines-of-argument synthesis embodying both perspectives. RESULTS Fifteen studies were included in the final syntheses. The results highlighted that there is a difference in attitudes and expectations between patients and HCPs regarding the disclosure conversation. Patients/family members expressed a need for information, the importance of sincere regret and a promise of improvement. However, HCPs faced several barriers, which hindered appropriate disclosure practices. These included difficulty of disclosure in a blame culture, avoidance of litigation, lack of skills on how to conduct disclosure and inconsistent guidance. A lines-of-argument synthesis is presented that identified both the key elements of an ideal disclosure desired by patients and the facilitators for HCPs, which can increase the likelihood of this taking place. CONCLUSIONS Although patients/family members and HCPs both advocate disclosure, several barriers prevent HCPs from conducting disclosure effectively. Both groups have different needs for disclosure. To meet patients' requirements, training on disclosure for HCPs and the development of an open, transparent culture within organizations are potential areas for intervention. © 2020 The Authors Health Expectations published by John Wiley & Sons Ltd.Ionic liquids and derivatives-mainly polymeric ionic liquids and magnetic ionic liquids-have been extensively used in microscale extraction over the past few years. Current trends in analytical sample preparation gear toward linking microextraction approaches with high-throughput sample processing to comply with green analytical chemistry requirements. A variety of high sample throughput strategies that are coupled to both ionic-liquid-based solid-phase microextraction and ionic liquid-based liquid-phase microextraction are herein reported. The review is focused on microscale extraction methods that use (i) custom-made and dedicated extraction devices, (ii) parallel extraction, (iii) magnetic-based separation, and (iv) miniaturized systems employing semi-automatic or fully automatic flow injection methods, related micro/millifluidic devices, and robotic equipment. © 2020 WILEY-VCH Verlag GmbH & Co.

The thin-film microextraction optimized method consisted of 60 min of extraction at pH 6.0 with the addition of sodium chloride (2-5%). Acetonitrile/water in the ratio of 82 was used for desorption analytes for 60 min. Evaluation of different extractive phases showed that polyacrylonitrile-polystyrene-divinylbenzene was the optimum coating. The linearity of the method was good in the range of 0.01-0.5 μg/mL for 14 fungicides with determination coefficients (R2 ) from 0.990 to 0.999, which indicated good linearity for both the grape juice and grape matrixes. The limit of detection was in the range of 0.002-0.01 μg/mL. The limit of quantitation was in the range of 0.01 mg/kg according to the minimum fortified level. The average absolute recoveries of the 14 fungicides ranged from 75.0 to 118.3%. The intraday relative standard deviation (n = 4) and interday relative standard deviation (n = 4) were 5.6-13.0% and 1.6-6.4%, respectively. This study showed that this method can be used for analyzing 96 samples in parallel, and the sample preparation time was approximately 2.0 min per sample. In addition, this approach offers a green and low-cost sample pretreatment technique for future analyses. © 2020 WILEY-VCH Verlag GmbH & Co.

This reaction is catalyzed by iron(II) and 2-oxoglutarate (Fe/2OG) dependent enzymes. Distinct from typical oxygenation or halogenation reactions catalyzed by this class of enzymes, installation of the isonitrile group represents a novel reaction type for Fe/2OG enzymes that involves a four-electron oxidative process. Reported here is a plausible mechanism of three Fe/2OG enzymes, Sav607, ScoE and SfaA, which catalyze isonitrile formation. The X-ray structures of iron-loaded ScoE in complex with its substrate and the intermediate, along with biochemical and biophysical data reveal that -N≡C bond formation involves two cycles of Fe/2OG enzyme catalysis. The reaction starts with an FeIV -oxo-catalyzed hydroxylation. It is likely followed by decarboxylation-assisted desaturation to complete isonitrile installation. © 2020 Wiley-VCH Verlag GmbH & Co.

These roles include the synthesis of essential membrane, storage, or surface lipids, as well as the production of various fatty acid-derived metabolites used for signaling or defense. Fatty acids are activated for metabolic processing via a thioester linkage to either coenzyme A or acyl carrier protein. Acyl synthetases metabolically activate fatty acids to their thioester forms, and acyl thioesterases deactivate fatty acyl thioesters to free fatty acids by hydrolysis. These two enzyme classes therefore play critical roles in lipid metabolism. This review highlights the surprisingly complex and varying roles of fatty acyl synthetases in plant lipid metabolism, including roles in the intracellular trafficking of fatty acids. This review also surveys the many specialized fatty acyl thioesterases characterized to date in plants, which produce a great diversity of fatty acid products in a tissue-specific manner.
