To introduce phase-cycled balanced SSFP (bSSFP) acquisition as an alternative in Fourier decomposition MRI for improved robustness against field inhomogeneities.

Series 2D dynamic lung images were acquired in 5 healthy volunteers at 1.5 T and 3T using bSSFP sequence with multiple RF phase increments and compared with conventional single RF phase increment acquisitions. The approach was evaluated based on functional map homogeneity analysis, while ensuring image and functional map quality by means of SNR and contrast-to-noise ratio analyses.

At both field strengths, functional maps obtained with phase-cycled acquisitions displayed improved robustness against local signal losses compared with single-phase acquisitions. The coefficient of variation (mean± SD, across volunteers) measured in the ventilation maps resulted in 29.7 ± 2.6 at 1.5T and 37.5 ± 3.1 at 3T for phase-cycled acquisitions, compared with 39.9 ± 5.2 at 1.5T and 49.5 ± 3.7 at 3T for single-phase acquisitions, indicating a significant improvement (

Phase-cycled bSSFP acquisitions improve robustness against field inhomogeneity artifacts and significantly improve ventilation map homogeneity at both field strengths. As such, phase-cycled bSSFP may serve as a robust alternative in lung function assessments.

Mostly, these liquid crystal (LC) configurations are uniquely determined by bulk LC elasticity, surface anchoring conditions, and confinement geometry. Here, we experimentally explore defect textures of the smectic LC phase in unique confining geometries with variable curvature. We show that a complex range of director configurations can arise from a single system, depending on sample processing procedures. Darapladib molecular weight Specifically, we report on LC textures in Janus drops comprised of silicone oil and 8CB in its smectic-A LC phase. The Janus droplets were made in aqueous suspension using solvent-induced phase separation. After drop creation, smectic layers form in the LC compartment, but their self-assembly is frustrated by the need to accommodate both the bowl-shaped cavity geometry and homeotropic (perpendicular) anchoring conditions at boundaries. A variety of stable and metastable smectic textures arise, including focal conic domains, dislocation rings, and undulations. We experimentally characterize their stabilities and follow their spatiotemporal evolution. Overall, a range of fabrication kinetics produce very different intermediate and final states. The observations elucidate assembly mechanisms and suggest new routes for fabrication of complex soft material structures in Janus drops and other confinement geometries.Correction for 'Glycyrrhizic acid promotes neural repair by directly driving functional remyelination' by Jing Tian et al., Food Funct., 2020, 11, 992-1005, https//doi.org/10.1039/C9FO01459D.
Decompressive craniectomy (DC) is a common procedure used for the treatment of intracranial hypertension. Once brain swelling has subsided, a cranioplasty is performed to restore cosmesis and protection to the brain. While using the patient's autologous bone flap is often the first choice in cranioplasty, this procedure is frequently complicated by bone flap resorption and infection. This study seeks to identify predictors of autologous cranioplasty failure.

A retrospective analysis was conducted on patients who underwent decompressive craniectomy and autologous cranioplasty. Patient demographics and factors related to both surgeries and failure rates were recorded from patient records. Logistic regressions were conducted to determine which factors were implicated in autologous cranioplasty failure.

In our cohort, 127 patients underwent autologous cranioplasty. Overall, 18 (14.2%) patients experienced autologous cranioplasty failure. Regression analysis identified development of post-traumatic hydroceph predictors of autologous cranioplasty failure. Interestingly, the presence of VP shunt did not impact the odds of flap failure.
Acutely symptomatic abdominal wall and groin hernias are a common reason for acute surgical hospital admissions. There are limited data to guide the treatment of these patients. This study aimed to assess outcomes of emergency hernia surgery and identify common management strategies, to improve care for these high-risk patients.

A 20-week, national multicentre, collaborative, prospective cohort study (NCT04197271) recruited adults with acutely symptomatic abdominal wall and groin hernias across the UK. Data on patient characteristics, inpatient management, quality of life, complications, and wound healing were collected. Follow-up telephone calls at 30 and 90 days were used to assessed complications and quality of life. Descriptive analyses were undertaken to describe the population and outcomes.

Twenty-three hospitals recruited 272 eligible patients. Inguinal (37.8 per cent) and umbilical (37.1 per cent) hernias were the most common. Some 13.9 per cent were awaiting elective surgery and 12.8 per cent honference, Birmingham, UK, March 2021, the Association of Surgeons of Great Britain and Ireland Congress, May 2021, the World Society of Emergency Surgery, Edinburgh, UK, September 2021, and the European Hernia Society Congress, Copenhagen, Denmark, October 2021.
There is variation in the investigation, management, and surgical technique used to treat acutely symptomatic abdominal wall and groin hernias in the UK. The optimal management strategy for specific acute presentations remains to be established.

Since known natural PKC agonists have little selectivity among the PKC isozymes, a new scaffold is needed to develop PKC ligands with remarkable isozyme selectivity. Taking advantage of machine-learning and computational chemistry approaches, we screened the PubChem database to select sesterterpenoids alotaketals as potential PKC ligands, then designed and synthesized alotaketal analogues with a different ring system and stereochemistry from the natural products. The analogue exhibited a one-order higher affinity for PKCα-C1A than for the PKCδ-C1B domain. Thus, this compound is expected to serve as the basis for developing PKC ligands with isozyme selectivity.
This work proposes "Spin-3/2 Bloch Equation" (SBE), a consolidated formalism for spin-3/2 dynamics in biological environments. The formalism encapsulates excitation, relaxation, and off-resonance with accessible matrix representation for a straightforward implementation with high computational efficiency.

The SBE is derived using spherical tensor operators to encapsulate the spin-3/2 dynamics in biological systems in a single system matrix, a formalism akin to the well-known Bloch Equations (BE).

Using the proposed SBE, simulations of three classical
Na pulse sequences were performed to demonstrate the versatility and applicability of the model, returning the evolution of the
Na spin system during these experiments soft rectangular and adiabatic inversion recovery (IR) and triple-quantum filtering. IR simulations were compared with two existing spin-3/2 simulators and the adaptive BE as a first-order approximation.

The proposed SBE is straightforward to implement and facilitates accurate and fast simulations of the underlying higher order coherence in sodium experiments of biological tissues. SBE simulations and comparison spin-3/2 simulators outperform the BE simulations as expected, with the SBE offering superior computational efficiency achieved by the single system matrix formalism.

The proposed SBE enables comprehensive and accurate simulations for spin-3/2 systems in biological tissue. With a one-line call to an ordinary differential equation solver, it offers a computationally efficient and accessible method for use in
Na pulse sequence design.

The Indian mangrove, or spurred mangrove, [Ceriops tagal (Perr.) C. B. Rob.] is a member of the Rhizophoraceae family and is commonly found along the intertidal zones in tropical regions in Southeast Asia, southern Asia, and Africa. Here, we present the first high-quality reference genome assembly of the Ceriops species. A preliminary draft assembly, generated from the 10× Genomics linked-read library, was scaffolded using the proximity ligation chromatin contact mapping technique (Hi-C) to obtain a chromosome-scale assembly of 231,919,005 bases with an N50 length of 11,408,429 bases. The benchmarking universal single-copy orthologs (BUSCO) analysis revealed that C. tagal gene predictions recovered 95.8% of the highly conserved orthologs. Phylogenetic analyses suggested that C. tagal diverged from the last common ancestor of flat-leaf spurred mangrove [C. decandra (Griff.) Ding Hou] and C. zippeliana Blume ∼10.4 million yr ago (MYA), and the last common ancestor of genera Ceriops, Kandelia, and Rhizophora diverged from that of genus Bruguiera ∼49.4 MYA. In addition, our analysis of the transversion rate at fourfold-degenerate sites from orthologous gene pairs provided evidence supporting a recent whole-genome duplication in C. tagal. The STRUCTURE and principal component analyses illustrated that C. tagal individuals investigated in this study were the admixture of two subpopulations, the genetic background of which was influenced primarily by location. The availability of genomic and transcriptomic resources and biodiversity data reported in this work will be useful for future studies that may shed light on adaptive evolutions of mangrove species.
Positron emission tomography (PET) myocardial perfusion imaging (MPI) is often combined with coronary artery calcium (CAC) scanning, allowing for a combined anatomic and functional assessment. We evaluated the independent prognostic value of quantitative assessment of myocardial perfusion and CAC scores in patients undergoing PET.

Consecutive patients who underwent Rb-82 PET with CAC scoring between 2010 and 2018, with follow-up for major adverse cardiovascular events (MACE), were identified. Perfusion was quantified automatically with total perfusion deficit (TPD). Our primary outcome was MACE including all-cause mortality, myocardial infarction (MI), admission for unstable angina, and late revascularization. Associations with MACE were assessed using multivariable Cox models adjusted for age, sex, medical history, and MPI findings including myocardial flow reserve.In total, 2507 patients were included with median age 70. During median follow-up of 3.9 years (interquartile range 2.1-6.1), 594 patients experienced at least one MACE.
