[Comprehensive Assessment of the Health Risk of Cadmium Exposure from Soil-wheat System in Wheat Fields in Northern China].

Accurately assessing the health risks of cadmium （Cd） exposure in the soil-wheat system is of great importance for the formulation of regional health risk prevention measures. Based on regional large-scale survey and Monte Carlo simulation methods, a case study on the health risk of Cd exposure in a soil-wheat system in a wheat production area of North China Plain was conducted by constructing a comprehensive health risk assessment （CHRA） model. The results showed that 73% of the soil samples in the study area exceeded the screening value of Cd for farmland soil （GB 15618-2018） and 57.

Morphine timing-dependent modulation of TRPV1 phosphorylation correlates with differential morphine effects on myocardial ischemia/reperfusion injury.

Opioids are used for pain relief in patients suffering from acute myocardial ischemia or infarction. Clinical and laboratory studies demonstrate that morphine treated patients or the experimental animal model suffering acute myocardial ischemia and reperfusion, may worsen myocardial viability. As transient receptor potential vanilloid 1 (TRPV1) plays important roles in pain sensation and cardio-protection, we query whether opioids may exacerbate myocardial viability via interaction with TRPV1 activity in the pain relief.

POSS hybrid bioactive glass dental composite resin materials: Synthesis and analysis.

Introduction: This study create a dental composite by hybirding polyhedral oligo-sesquioxide nano monomers and bioactive glass BG 45S5.

Methods: Make an experimental composite resin material with a 60 % filler content overall by substituting 20 % of the filler with BG 45S5. The experimental resins are grouped and named P0, P2, P4, P6 and P8 based on the reactive nanomonomer methacrylic acid-based multifaceted oligomeric sesquisiloxane (POSS) added by 2 %-8 % in the resin matrix portion of each group.

Epidural administration of large dose of opioid μ receptor agonist may impair cardiac functions and myocardial viability via desensitizing transient receptor potential vanilloid 1.

The incidence of postoperative myocardial injury remains high as the underlying pathogenesis is still unknown. The dorsal root ganglion (DRG) neurons express transient receptor potential vanilloid 1 (TRPV1) and its downstream effector, calcitonin gene-related peptide (CGRP) participating in transmitting pain signals and cardiac protection. Opioids remain a mainstay therapeutic option for moderate-to-severe pain relief clinically, as a critical component of multimodal postoperative analgesia via intravenous and epidural delivery.

Di-(2-ethylhexyl) phthalate exacerbates abnormalities of testicular development in F1 males via inhibition the Wnt/β-catenin signaling pathway.

The theory of "Developmental Origins of Health and Disease (DOHaD)" espouses that environmental exposures to toxicants during critical developmental stages can affect health outcomes in adulthood. Di (2-ethylhexyl) phthalate (DEHP) is a plasticizer that can be transferred to developing organisms via the placenta and breast milk as an environmental endocrine disruptor. We herein implemented a cross-fostering model to decipher the contributions of prenatal vs.

[Prediction of Cadmium Uptake Factor in Wheat Based on Machine Learning].

Applying machine learning methods to resolve the cadmium (Cd) uptake characteristics of regional soil-wheat systems can contribute to the accuracy and rationality of risk decisions. Based on a regional survey, we constructed a Freundlich-type transfer equation, random forest (RF) model, and neural network (BPNN) model to predict wheat Cd enrichment factor (BCF-Cd); verified the prediction accuracy; and assessed the uncertainty of different models. The results showed that both RF (=0.

[Characteristics of condylography during masticatory movement in patients with Class Ⅱ division 1 malocclusion and temporomandibular disorders].

Purpose: To investigate the characteristics of condylography of masticatory movement in patients of Class Ⅱ division 1 malocclusion with temporomandibular disorders (TMD), and the effects of TMD and Angle Ⅱ1 malocclusion factors on the condylography of masticatory movement.

Methods: According to the inclusion criteria of the experiment, ten normal occlusion subjects without TMD（nTMD-N）, ten Angle Ⅱ1 patients without TMD（nTMD-Ⅱ1）and 14 Angle Ⅱ1 patients with TMD（TMD-Ⅱ1）were included. Cadiax IV was used to record the condylography of the subjects during mastication, and the data of condylography was measured and analyzed by GDSW software.

Circ-sh3rf3/GATA-4/miR-29a regulatory axis in fibroblast-myofibroblast differentiation and myocardial fibrosis.

The transdifferentiation from cardiac fibroblasts to myofibroblasts is an important event in the initiation of cardiac fibrosis. However, the underlying mechanism is not fully understood. Circ-sh3rf3 (circular RNA SH3 domain containing Ring Finger 3) is a novel circular RNA which was induced in hypertrophied ventricles by isoproterenol hydrochloride, and our work has established that it is a potential regulator in cardiac hypertrophy, but whether circ-sh3rf3 plays a role in cardiac fibrosis remains unclear, especially in the conversion of cardiac fibroblasts into myofibroblasts.

[Assessing the Lead Accumulation Risks of Wheat Grain by Developing a Source-Specific Accumulation Risk Assessment Model].

Characterizing the lead (Pb) transfer in the "source-soil-wheat" chain is of great importance for the prevention and control of the Pb accumulation risk in wheat grain harvested from the croplands of China. In this study, we used the Jiyuan City, northern China, as a case study to investigate the influence of contamination sources and soil factors on the accumulation of Pb in wheat grain. A site-specific source risk assessment model (SRAM), coupling the positive matrix factorization model, Freundlich-type function, and the Monte Carlo simulation method, was developed to estimate the risk of Pb accumulation in wheat grain harvested from different scenarios.
