Aims: This study aims to evaluate and validate a simple quantitative ultrasound (US) method for determining the hepatic fat content (HFC) based on the combination of quantitative US hepatic/renal ratio (US-HRR) and quantitative US hepatic echo-intensity attenuation rate (US-HAR) as compared with [1H]-magnetic resonance spectroscopy (1H-MRS).
Material And Methods: There were a total of 242 subjects recruited in the present study. All subjects were examined for HFC by quantitative US and 1H-MRS methods. The QUS-HRR and QUS-HAR were calculated from ordinary ultrasound images of liver and kidney with a triple modality 3D abdominal phantom using the Image J software.
Results: The results found that US-HRR and US-HAR correlated with 1H-MRS HFC (US-HRR: r=0.946, p<0.001; US-HAR: r=0.936, p<0.001). The equation for HFC prediction by using quantitative US was: HFC (%) = 28.965 × US-HRR + 218.045 × US-HAR - 8.892. Subgroup analysis in study subjects with body mass index (BMI) ≥28 showed that quantitative US HFC was associated with 1H-MRS HFC (R2=0.953, p<0.001). Receiver operating characteristic (ROC) analysis observed that the cut-off value of fatty liver diagnosis was 6.71% in using the quantitative US model; the sensitivity and specificity for fatty liver diagnosis were 94.15% and 96.30%, respectively. Variability analysis indicated that there was a relative high degree of consistency in the measurement of HFC with different operators or ultrasonic apparatus.
Conclusions: Quantitative US measurement could be regarded as a simple, sensitive tool to accurately assess HFC. It provides a valid alternative to 1H-MRS as an easy, non-invasive option for the precise estimation of HFC in clinical practice.

Evaluation of a potential bidirectional influence of metabolic syndrome and apical periodontitis: An animal-based study.

Aim: This study aimed to explore the possible bidirectional interrelations between fructose-induced metabolic syndrome (MS) and apical periodontitis (AP).
Methodology: Twenty-eight male Wistar rats were distributed into four groups (n = 7, per group): Control (C), AP, Fructose Consumption (FRUT) and Fructose Consumption and AP (FRUT+AP). The rats in groups C and AP received filtered water, while those in groups FRUT and FRUT+AP received a 20% fructose solution mixed with water to induce MS.

High sugar intake, particularly fructose, is implicated in obesity and metabolic complications. On the other hand, fructose from fruits and vegetables has undisputed benefits for metabolic health. This raises a paradoxical question-how the same fructose molecule can be associated with detrimental health effects in some studies and beneficial in others.

Background/objectives: This study builds on previous findings from mouse models, which showed that maternal overnutrition induced by a high-fat diet (HFD) promotes metabolic-associated fatty liver disease (MAFLD) in offspring, linked to global DNA hypermethylation. We explored whether epigenetic modulation with 5-Aza-CdR, a DNA methylation inhibitor, could prevent MAFLD in offspring exposed to maternal overnutrition.
Methods: The offspring mice from dams of maternal overnutrition were fed either a chow diet or a high-fat diet (HFD) for 10 weeks.

Background/objectives: Type 2 diabetes mellitus (T2DM) is considered a serious risk to public health since its prevalence is rapidly increasing worldwide despite numerous therapeutics. Insulin resistance in T2DM contributes to chronic inflammation and other metabolic abnormalities that generate fat accumulation in the liver, eventually leading to the progression of metabolic dysfunction-associated fatty liver disease (MAFLD). Recently, the possibility that microbial-derived metabolites may alleviate MAFLD through enterohepatic circulation has emerged, but the underlying mechanism remains unclear.

A diet containing foods that are sources of S-methylmethionine (SMM), and its use as a dietary supplement, have demonstrated beneficial health effects. Thus, the objective of this work was to evaluate the inclusion of SMM as a dietary supplement in C57BL/6J high-fat-fed mice to verify whether this compound alone would be responsible for these positive effects. Mice were divided into three groups: LF (low-fat diet), HF (high-fat diet), and HF+SMM (high-fat diet plus SMM), and maintained for 10 weeks with water and food provided ad libitum.
