Fatty acid can potentially serve as biomarker for evaluating metabolic disorder and inflammation condition, and quantifying the double bonds is the key for revealing fatty acid information. This study presents an assessment of a deep learning approach utilizing deep image prior (DIP) for the quantification of double bonds and methylene-interrupted double bonds of triglyceride derived from chemical-shift encoded multi-echo gradient echo images, all achieved without the necessity for network training. The methodology implemented a cost function grounded in signal constraints to continually refine the neural network's parameters on a single slice of images through iterative processes.

Article Synopsis
  • A study analyzed the link between fruit and vegetable consumption and blood pressure (BP) and body mass index (BMI) by using objective measurements instead of self-reported dietary assessments, which can be unreliable.
  • Researchers used advanced techniques to analyze urine samples from participants in the US and UK, identifying specific metabolites associated with fruit and vegetable intake.
  • The findings showed that certain metabolites were inversely related to systolic BP and BMI, highlighting that higher fruit and vegetable intake could lead to lower BP and BMI, largely due to citrate levels in urine.

In autonomous driving, environmental perception technology often encounters challenges such as false positives, missed detections, and low accuracy, particularly in detecting small objects and complex scenarios. Existing algorithms frequently suffer from issues like feature redundancy, insufficient contextual interaction, and inadequate information fusion, making it difficult to perform multi-task detection and segmentation efficiently. To address these challenges, this paper proposes an end-to-end multi-task environmental perception model named YOLO-Mg, designed to simultaneously perform traffic object detection, lane line detection, and drivable area segmentation.

Introduction: Low-income families are exposed to adverse childhood experiences and psychosocial risks that impact child development. At the KK Women's and Children's Hospital in Singapore, Kids Integrated Development Service (KIDS0-3) is a home visitation programme that aims to optimise the development of children from low-income families.

Method: Data comprising family demographics, maternal psychosocial risks and outcomes of child development were collated through a chart review of 469 mother-child dyads enrolled from June 2014 to October 2022.

  • Hypertensive individuals experience greater increases in blood pressure (BP) with decreases in environmental temperature compared to non-hypertensive individuals, especially during winter.
  • The study monitored 251 elderly participants and found that a 1°C drop in temperature resulted in a significant rise in systolic and diastolic BP for hypertensive individuals, while non-hypertensive individuals showed smaller changes.
  • The blood pressure response peaked within the first hour after a temperature drop and diminished over the next 10 hours, suggesting potential interventions should target immediate factors following temperature changes.

Stereotactic body radiation therapy (SBRT) is an increasingly used alternative treatment option for nonresectable hepatocellular carcinoma (HCC) in people. Comparatively, the publication of SBRT of dogs with HCC is limited. The objective of this retrospective, descriptive case series was to evaluate the clinical outcomes and toxicity data of SBRT in dogs with HCC and imaging-documented primary liver tumors using volumetric-modulated arc therapy delivery at two private institutions.

  • The study examined how calcium and magnesium intake from the DASH diet and other sources relate to blood pressure, focusing on diet quality as indicated by DASH scores.
  • Data from 2,195 participants (ages 40-59) were analyzed, involving dietary recalls and blood pressure measurements to determine the impact of these nutrients on systolic blood pressure (SBP).
  • Results showed that higher DASH scores and greater intakes of calcium and magnesium were consistently linked to lower SBP, indicating a positive relationship between these nutrients and blood pressure control, regardless of their dietary source.

Multi-parametric mapping of MRI relaxations in liver has the potential of revealing pathological information of the liver. A self-supervised learning based multi-parametric mapping method is proposed to map T and T simultaneously, by utilising the relaxation constraint in the learning process. Data noise of different mapping tasks is utilised to make the model uncertainty-aware, which adaptively weight different mapping tasks during learning.

  • The phosphate oxygen isotope (δO) technique is useful for tracking phosphorus sources and transformations, but existing pretreatment methods for sediments are not widely applicable.
  • This study focuses on optimizing the δO pretreatment process for sediments, using the Fuyang River Basin and South Lake as a case study, and compares the effectiveness of the Blake and McLaughlin methods.
  • Results showed that the Blake method is superior in phosphorus recovery and organic matter removal, and after optimizing it further, the method improved efficiency and reduced experimental time, providing a more practical solution for broader use of sediment δO technology.

  • Branched-chain amino acids (BCAAs) are important indicators of metabolic health and can reflect the risk of cardiometabolic diseases in older adults, particularly those aged 65 and over.
  • A study measuring BCAA levels over a 14-year period found that higher BCAA levels correlated with reduced mortality risk in older adults without hypertension or diabetes, while those with these conditions showed a more complex, U-shaped relationship.
  • Overall, the research highlighted that both abnormally high and low BCAA levels in older adults with hypertension or diabetes were linked to increased mortality risks, emphasizing the importance of context in interpreting BCAA levels.

The increase in new cases of drug resistance to first-line drugs such as ethambutol (ETB) makes it necessary to develop improvements for antituberculosis drugs. A new method for improving the bioavailability of active pharmaceutical ingredient (API) was investigated for preventing drug resistance and side-effects of antituberculosis drugs. In this study, an antituberculosis drug delivery system using β-cyclodextrin (β-CD) as the supramolecular carrier of ETB was prepared using the kneading method.

We explore a series of furan-based non-fullerene acceptors and report their optoelectronic properties, solid-state packing, photodegradation mechanism and application in photovoltaic devices. Incorporating furan building blocks leads to the expected enhanced backbone planarity, reduced band gap and red-shifted absorption of these acceptors. Still, their position in the molecule is critical for stability and device performance.

Proteins generally achieve their functions through interactions with other proteins, so being able to determine which proteins interact with which other proteins underlies much of molecular biology. Co-fractionation (CF) is a mass spectrometry-based method for detecting proteome-wide protein-protein interactions. An attractive feature of CF is that it is not necessary to label or otherwise alter samples.

Demographic and clinical factors influence the metabolome. The discovery and validation of disease biomarkers are often challenged by potential confounding effects from such factors. To address this challenge, we investigated the magnitude of the correlation between serum and urine metabolites and demographic and clinical parameters in a well-characterized observational cohort of 444 post-menopausal women participating in the Women's Health Initiative (WHI).
