Reproducibility of automatic adipose tissue segmentation using proton density fat fraction images between 1.5 and 3.0 T magnetic resonance.

Background: Deep learning (DL)-based adipose tissue segmentation methods have shown great performance and efficacy for adipose tissue distribution analysis using magnetic resonance (MR) images, an important indicator of metabolic health and disease. The aim of this study was to evaluate the reproducibility of whole-body adipose tissue distribution analysis using proton density fat fraction (PDFF) images at different MR strengths.

Methods: A total of 24 volunteers were imaged using both 1.

A rapid chemical reprogramming system to generate human pluripotent stem cells.

Chemical reprogramming enables the generation of human pluripotent stem (hCiPS) cells from somatic cells using small molecules, providing a promising strategy for regenerative medicine. However, the current method is time consuming, and some cell lines from different donors are resistant to chemical induction, limiting the utility of this approach. Here, we developed a fast reprogramming system capable of generating hCiPS cells in as few as 10 days.

Effect of IV Thrombolysis With Alteplase in Patients With Vessel Occlusion in the WAKE-UP Trial.

Background And Objectives: Data from randomized trials on the treatment effect of pure thrombolysis in patients with vessel occlusion are lacking. We examined data from a corresponding subsample of patients from the multicenter, randomized, placebo-controlled WAKE-UP trial to determine whether MRI-guided IV thrombolysis with alteplase in unknown-onset ischemic stroke benefits patients presenting with vessel occlusion.

Methods: Patients with an acute ischemic lesion visible on MRI diffusion-weighted imaging but no marked parenchymal hyperintensity on fluid-attenuated inversion recovery images were randomized to treatment with IV alteplase or placebo.

Thermodynamic analysis of the effect of palm stearin on fully hydrogenated soybean oil coatings in granular micronutrient premixes.

This study examined the phase behaviour and temperature-dependent viscosity of palm stearin and fully hydrogenated soybean oil (FHSBO) mixtures to understand the stability of FHSBO coatings on micronutrient premixes. The Hildebrand equation showed that palm stearin/FHSBO mixtures form liquid solutions, while DSC data indicated partial immiscibility in the solid phase. The melting temperatures and enthalpies of fusion are composition dependent, ranging from 67 °C and 138 J/g for 100 % FHSBO to 13 °C and 71 J/g for 100 % palm stearin.

Structural barriers governing starch digestibility in intact highland barley cells: A closer insight from cell wall and protein matrix.

The endosperm cell structure plays an important role in starch digestion. This study aimed to evaluate the effects of the structural properties of the cell wall and protein matrix on starch digestibility in intact cells isolated from the endosperm of highland barley. Damaged cells with different degree of cell wall degradation were obtained by controlling the time of β-glucanase hydrolysis of isolated cells.

CT-FFR by expanding coronary tree with Newton-Krylov-Schwarz method to solve the governing equations of CFD.

Aims: A new model of computational fluid dynamics (CFD)-based algorithm for coronary CT angiography (CCTA)-derived fractional flow reserve (FFR) (CT-FFR) analysis by expanding the coronary tree to smaller-diameter lumen (0.8 mm) using Newton-Krylov-Schwarz (NKS) method to solve the three-dimensional time-dependent incompressible Navier-Stokes equations has been developed; however, the diagnostic performance of this new method has not been sufficiently investigated. The aim of this study was to determine the diagnostic performance of a novel CT-FFR technique by expanding the coronary tree in the CFD domain.

Interannual succession of phytoplankton community in a canyon-shaped drinking water reservoir during the initial impoundment period: Taxonomic versus functional groups.

During the initial impoundment period of a canyon-shaped reservoir, the water body fluctuated violently regarding water level, hydrological condition, and thermal stratification. These variations may alter the structure of phytoplankton community, resulting in algal blooms and seriously threatening the ecological security of the reservoir. It is of great significance to understand the continuous changes of phytoplankton in the initial impoundment period for the protection of reservoir water quality.

Preparation and application of high thermal conductivity phase change microcapsules with fluorescence characteristics based on a ZnWO shell.

Phase change microcapsules (NePCMs) with high latent heat values, thermal conductivity and stability were synthesized by coating stearic acid (SA) phase change materials (PCMs) with zinc tungstate (ZnWO) as the shell material. The prepared ZnWO and microcapsule samples are characterized through various techniques, and their thermophysical properties under different core-shell ratios and emulsifiers are compared. The highest value that the phase transition enthalpy reaches is 83.

Supramolecular assembly of polycation/mRNA nanoparticles and in vivo monocyte programming.

Size-dependent phagocytosis is a well-characterized phenomenon in monocytes and macrophages. However, this size effect for preferential gene delivery to these important cell targets has not been fully exploited because commonly adopted stabilization methods for electrostatically complexed nucleic acid nanoparticles, such as PEGylation and charge repulsion, typically arrest the vehicle size below 200 nm. Here, we bridge the technical gap in scalable synthesis of larger submicron gene delivery vehicles by electrostatic self-assembly of charged nanoparticles, facilitated by a polymer structurally designed to modulate internanoparticle Coulombic and van der Waals forces.

Blood protein assessment of leading incident diseases and mortality in the UK Biobank.

We report 3,209 associations between 963 protein levels and 21 incident outcomes.

Polymeric Fibers with High Strength and High Toughness at Extreme Temperatures.

Developing strong and simultaneously tough polymeric materials with excellent thermal stability and mechanical performance even under extreme temperatures is truly a challenge. In a disruptive progress, continuous polymeric yarns are developed with a combination of high tensile strength of (1145 ± 44) MPa and ultrahigh toughness of (350 ± 24) J g and high thermomechanical properties from -196 to 200 °C. The comprehensive thermomechanical performance of this yarn surpasses that of previously developed polymeric materials and dragline spider silks.

Integrative molecular and spatial analysis reveals evolutionary dynamics and tumor-immune interplay of in situ and invasive acral melanoma.

In acral melanoma (AM), progression from in situ (AMis) to invasive AM (iAM) leads to significantly reduced survival. However, evolutionary dynamics during this process remain elusive. Here, we report integrative molecular and spatial characterization of 147 AMs using genomics, bulk and single-cell transcriptomics, and spatial transcriptomics and proteomics.

Thermal decomposition characteristics of BHT and its peroxide (BHTOOH).

2,6-Di-tert-butyl-4-methylphenol (BHT) is an excellent antioxidant that is easily oxidized to 2,6-di-tert-butyl-4-hydroperoxyl-4-methyl-2,5-cyclohexadienone (BHTOOH). For the safety of BHT production and usage, it is meaningful to study the thermal stability and decomposition properties of BHT and BHTOOH. In this paper, the thermal decomposition properties of BHT and BHTOOH were compared by the mini closed pressure vessel test (MCPVT) and differential scanning calorimetry (DSC).

Aims: Homozygous familial hypercholesterolaemia (HoFH) is a rare disorder characterized by markedly elevated circulating low-density lipoprotein cholesterol (LDL-C) from birth. This review aimed to critically evaluate treatments for HoFH with respect to their efficacy, safety, accessibility, overall context and position within the treatment pathway.

Methods And Results: A mixed-methods review was undertaken to systematically identify and characterize primary interventional studies on HoFH, with a focus on LDL-C reduction as the primary outcome.

Clinical effectiveness of a multitarget urine DNA test for urothelial carcinoma detection: a double-blinded, multicenter, prospective trial.

Urine-based testing is promising for noninvasive diagnosis of urothelial carcinoma (UC) but has suboptimal sensitivity for early-stage tumors. Herein, we developed a multitarget urine tumor DNA test, UI-Seek, for UC detection and evaluated its clinical feasibility. The prediction model was developed in a retrospective cohort (n = 382), integrating assays for FGFR3 and TERT mutations and aberrant ONECUT2 and VIM methylation to generate a UC-score.
