The developed method was successfully applied for monitoring market samples collected throughout the Korean Peninsula, and none of the samples tested positive for the target analytes. It has therefore been shown that dehydration and acidification were effective to extract spinosad from animal-derived products.
Digital interventions are effective for reducing alcohol consumption but evidence is limited regarding smartphone apps. Drink Less is a theory- and evidence-informed app to help people reduce their alcohol consumption that has been refined in terms of its content and design for usability across the sociodemographic spectrum. We aim to evaluate the effectiveness and cost-effectiveness of recommending Drink Less at reducing alcohol consumption compared with usual digital care.
Two-arm individually randomised controlled trial.
Online trial in the United Kingdom (UK).
Hazardous or harmful drinkers (Alcohol Use Disorders Identification Test [AUDIT] score ≥8) aged 18+who want to drink less alcohol (n=5562). Participants will be recruited from July 2020 to May 2022 using multiple strategies with a focus on remote digital methods.
Participants will be randomised to receive either an email recommending that they use Drink Less (intervention) or view the National Health Service (NHS) webpage on alcohol advicelcohol reduction app for the general population in the United Kingdom. This study will inform the decision on whether it is worth investing resources in large-scale implementation.
This study will establish the effectiveness and cost-effectiveness of the Drink Less app at reducing alcohol consumption among hazardous and harmful adult drinkers and will be the first randomised controlled trial of an alcohol reduction app for the general population in the United Kingdom. This study will inform the decision on whether it is worth investing resources in large-scale implementation.Onychopapilloma is a fairly common lesion that is clinically typical enough to make the diagnosis. It is unique in that it stretches from the distal matrix all along the nailbed to the hyponychium. A case is described that developed pain eventually resulting in total excision. Histopathology revealed a malignant onychopapilloma. The differential diagnosis of this lesion is discussed.In this study, a simple and sensitive LC-tandem mass spectrometric method was developed and validated for the determination of LNP023 in rat plasma. The plasma sample was precipitated with acetonitrile and then separated on an ACQUITY HSS T3 column (50 mm × 2.1 mm, 1.8 μm) using 0.1% formic acid in water and acetonitrile as the mobile phase. The MS detection was performed in positive multiple-reaction monitoring mode with precursor-to-product ion transitions of m/z 423.3 → 174.1 and m/z 435.3 → 367.1 for LNP023 and olaparib (internal standard), respectively. The developed assay was validated in the linear range of 0.1-1000 ng/mL with correlation coefficient (r) greater than 0.9992. The validation parameters were all within the acceptable limits. The validated method has been successfully used to investigate the pharmacokinetics of LNP023 in rat plasma, and our results indicated that LNP023 showed low clearance and high bioavailability (62.2%). Furthermore, four minor metabolites from rat plasma were detected and identified by LC combined with high-resolution mass spectrometry. The metabolic pathways were O-deethylation (M1), hydroxylation (M4), oxidation (M3), and acyl-glucuronidation (M2).Antarctic krill oil (AKO) is usually encapsulated by the protein materials, enhancing its oxidative stability. Proteins exhibit immense effect on lipid oxidation and induce protein-lipid co-oxidation. This study aimed at elucidating the co-oxidation mechanism of AKO and whey protein (WP) or myofibrillar protein (MP) in oil-in-water emulsions. The estimations of malondialdehyde (MDA) content, phospholipid molecular species, and pyrrole content resulted in increased and decreased oxidation rate of AKO (especially phosphatidylethanolamine) by WP and MP, respectively. Meanwhile, protein concentration, sulfhydryl content, the loss of tryptophan fluorescence intensity, and sodium dodecyl sulfate-polyacrylamide gel electrophoresis results demonstrated that AKO promoted WP oxidation but inhibited MP oxidation. Further, the antioxidative abilities of seven common antioxidants were evaluated. Ascorbyl palmitate showed the most substantial antioxidative effect for both AKO and proteins (about 70% decrease of MDA content and 30% decrease of the decrease ratio of tryptophan fluorescence intensity). This finding supported that different proteins could exhibit different pro/anti-oxidative effects on lipid oxidation, especially for marine lipids abundant in phospholipids and polyunsaturated fatty acids. Besides, MP could also act as antioxidant in MP AKO emulsions, further extending its application from traditional surfactants. PRACTICAL APPLICATION AKO is usually encapsulated by the protein materials, enhancing its oxidative stability. The results demonstrated MP could inhibit AKO oxidation, and vice versa, especially when ascorbyl palmitate was added at the same time. As a result, this finding explored a new potential wall material with antioxidative ability for the encapsulated products of AKO.The biosynthesis of thioamitide natural products remains largely unknown, especially for the characteristic C-terminal 2-aminovinyl-cysteine (AviCys) motifs. Herein, we report the discovery that homologues of class-III lanthipeptide synthetases (LanKCt s) encoded outside putative thioamitide biosynthetic gene clusters (BGCs) fully dehydrate the precursor peptides. LanKCt enzymes bind tightly to cysteine decarboxylases encoded inside thioamitide BGCs and the resulting enzyme complex completes the macrocyclization of AviCys rings. Furthermore, LanKCt enzymes are present in the genomes of many thioamitide-producing strains and participate in the generation of AviCys macrocycles. Together, our study reveals an unprecedented system that lanthipeptide synthetases outside thioamitide BGCs participate in their biosynthesis by specific association with cysteine decarboxylases encoded inside BGCs.
Diffusion-weighted imaging (DWI) has shown promise to screen for breast cancer without a contrast injection, but image distortion and low spatial resolution limit standard single-shot DWI. Multishot DWI methods address these limitations but introduce shot-to-shot phase variations requiring correction during reconstruction.
To investigate the performance of two multishot DWI reconstruction methods, multiplexed sensitivity encoding (MUSE) and shot locally low-rank (shot-LLR), compared to single-shot DWI in the breast.
Prospective.
A total of 45 women who consented to have multishot DWI added to a clinically indicated breast MRI.
Single-shot DWI reconstructed by parallel imaging, multishot DWI with four or eight shots reconstructed by MUSE and shot-LLR, 3D T
-weighted imaging, and contrast-enhanced MRI at 3T.
Three blinded observers scored images for 1) general image quality (perceived signal-to-noise ratio [SNR], ghosting, distortion), 2) lesion features (discernment and morphology), and 3) perceiR reconstructs multishot DWI with minimal ghosting artifacts. The improvement of multishot DWI in image quality increases with an increased number of shots.
2 TECHNICAL EFFICACY STAGE 2.
2 TECHNICAL EFFICACY STAGE 2.Curcumin solid dispersions were prepared using hydroxypropyl methylcellulose (HPMC) to enhance water solubility of curcumin. The particle size of curcumin solid dispersions was in range from 371 to 528 nm and particles were shaped as spherical with wrinkles. The encapsulation efficiency was over 93% for all samples, and water solubility of curcumin was significantly improved to 238 µg/mL when the ratio of curcumin to HPMC was 2080. The results of X-ray diffraction, differential scanning calorimeter, and Fourier transform infrared spectroscopy showed that crystalline form of curcumin changed to amorphous form. Curcumin solid dispersions showed improved dissolution behavior compared to pure curcumin and the curcumin release kinetic studies were applied to find best-fitting model. find more This study showed a great potential of solid dispersion using HPMC as curcumin delivery system with improved water solubility and oral absorption. PRACTICAL APPLICATION Curcumin has limited applications in the food industry because of low water solubility. Dongoh water-soluble curcumin (DW-CURs) were prepared by solid dispersion method with HPMC. Our results indicated that curcumin solid dispersions improved the water solubility of curcumin and showed a sustained release, demonstrating its possibility of body application. Therefore, DW-CURs are a promising formulation for application as a functional ingredient in the food industry.Enyne monomers derived from D-xylose underwent living cascade polymerizations to prepare new polymers with a ring-opened sugar and degradable linkage incorporated into every repeat unit of the backbone. Polymerizations were well-controlled and had living character, which enabled the preparation of high molecular weight polymers with narrow molecular weight dispersity values and a block copolymer. By tuning the type of acid-sensitive linkage (hemi-aminal ether, acetal, or ether functional groups), we could change the degradation profile of the polymer and the identity of the resulting degradation products. For instance, the large difference in degradation rates between hemi-aminal ether and ether-based polymers enabled the sequential degradation of a block copolymer. Furthermore, we exploited the generation of furan-based degradation products, from an acetal-based polymer, to achieve the release of covalently bound reporter molecules upon degradation.With the growing incidence of diabetes mellitus (DM), an increasing number of organ donors with DM can be expected. We sought to investigate the association between donor DM with early post-transplant outcomes. From a national cohort of adult liver transplant recipients (1996-2016), all recipients transplanted with a liver from a DM donor (n = 69) were matched 12 with recipients of livers from non-DM donors (n = 138). The primary end-point included early post-transplant outcome, such as the incidence of primary nonfunction (PNF), hepatic artery thrombosis (HAT), and 90-day graft survival. Cox regression analysis was used to analyze the impact of donor DM on graft failure. PNF was observed in 5.8% of grafts from DM donors versus 2.9% of non-DM donor grafts (P = 0.31). Recipients of grafts derived from DM donors had a higher incidence of HAT (8.7% vs. 2.2%, P = 0.03) and decreased 90-day graft survival (88.4% [70.9-91.1] vs. 96.4% [89.6-97.8], P = 0.03) compared to recipients of grafts from non-DM donors. The adjusted hazard ratio for donor DM on graft survival was 2.21 (1.08-4.53, P = 0.03). In conclusion, donor DM is associated with diminished outcome early after liver transplantation. The increased incidence of HAT after transplantation of livers from DM donors requires further research.As stroke mortality rates decrease, there has been a surge of effort to study poststroke dementia (PSD) to improve long-term quality of life for stroke survivors. Hippocampal volume may be an important neuroimaging biomarker in poststroke dementia, as it has been associated with many other forms of dementia. However, studying hippocampal volume using MRI requires hippocampal segmentation. Advances in automated segmentation methods have allowed for studying the hippocampus on a large scale, which is important for robust results in the heterogeneous stroke population. However, most of these automated methods use a single atlas-based approach and may fail in the presence of severe structural abnormalities common in stroke. Hippodeep, a new convolutional neural network-based hippocampal segmentation method, does not rely solely on a single atlas-based approach and thus may be better suited for stroke populations. Here, we compared quality control and the accuracy of segmentations generated by Hippodeep and two well-accepted hippocampal segmentation methods on stroke MRIs (FreeSurfer 6.
