Aim: To evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) in the management of pyrrolizidine alkaloid-related hepatic sinusoidal obstruction syndrome (PA-HSOS) and to identify key factors influencing the recovery of liver imaging manifestation after TIPS procedure in PA-HSOS patients.

Methods: A retrospective review was conducted of 30 PA-HSOS patients who received TIPS at Jinhua Municipal Central Hospital between 1 January 2018, and 30 September 2021, following failure of anticoagulation-based comprehensive treatments. Baseline characteristics and follow-up data were collected, including clinical manifestations, laboratory test results, computed tomography (CT) radiological manifestations of the liver, hepatic venous pressure gradient (HVPG), survival, and complications.

Accurate prediction of viscosity remains a challenge in industry due to the lack of reliable simple universal models. This work investigates the accuracy of four cubic equations of state (EOS) with different α functions for pure fluid viscosity predictions based on the residual entropy scaling (RES). The cubic EOS are Peng-Robinson (PR), Soave-Redlich-Kwong (SRK), Patel-Teja-Valderrama (PTV), and Yang-Frotscher-Richter (YFR), and the α functions are those proposed by Twu et al.

Non-alcoholic fatty liver disease (NAFLD) is strongly associated with dyslipidemia, and the non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) is a more comprehensive indicator of lipids. This study aimed to investigate the association between NHHR and hepatic steatosis and liver fibrosis. The 2017-2020 national health and nutrition examination survey (NHANES) dataset was used for the cross-sectional survey.

Background: Gastroesophageal reflux disease (GERD) is a chronic condition of the digestive tract with limited therapeutic options. Bitter taste receptors (TAS2Rs) and transient receptor potential vanilloid-1 (TRPV1) are implicated in modulating inflammatory responses. Berberine (BBR) and evodiamine (EVO) are known to activate TAS2Rs and TRPV1, respectively.

Article Synopsis
  • Recent advancements in the residual entropy scaling (RES) method have improved the modeling of transport properties, particularly in thermal conductivity of various fluids.
  • A new RES model expands upon previous work by Yang et al., utilizing experimental data from the NIST ThermoData Engine to analyze 125 pure fluids and 164 mixtures, achieving high accuracy with over 68% of data matching within close ranges.
  • The RES model showcases comparable performance to existing models in REFPROP 10.0 but uses fewer parameters, plus a Python software package is available for easy implementation of the model.

Article Synopsis
  • Obesity is linked to gastrointestinal issues, and the visceral adiposity index (VAI) helps assess visceral fat's impact on bowel habits and inflammatory bowel disease (IBD).
  • A study using the NHANES dataset analyzed over 10,000 adults, finding a significant negative relationship between higher VAI and chronic constipation, while no clear link was found with IBD.
  • The research also revealed a complex relationship between VAI and chronic diarrhea, suggesting moderate visceral fat levels can help prevent chronic constipation and may lower the risk of chronic diarrhea, with healthy sleep contributing positively to bowel health.

Neonicotinoids (NEOs) are widely used insecticides and have been detected in aquatic environments globally. However, little is known about NEOs contamination in the coastal environments under the terrestrial pressure of multiple planting types simultaneously. This study investigated the occurrence, spatial-seasonal variability, and ecological risks of NEOs along the coast of the Shandong Peninsula during the dry and wet seasons, where located many largest fruit, vegetable, and grain production bases in China.

Background: Individuals with refractory ascites in the context of liver cirrhosis typically face an adverse prognosis. The transjugular intrahepatic portosystemic shunt (TIPS) is an efficacious intervention, but there is a lack of reliable tools for postoperative prognosis assessment. Previously utilized clinical biochemical markers, such as the serum albumin concentration (Alb), sodium (Na) concentration, and serum creatinine (Scr), have limited predictive value.

Organophosphate esters (OPEs) as substitutes for PBDEs have been widely detected in the marine environment, while little is known about the pollution characteristics and variation of OPEs in estuarine environments with complex hydrodynamic conditions and land-based input. Yangtze River Estuary (YRE) is a typical highly urbanized and industrialized estuary, with a complex hydrological environment and geochemical behavior. This study found that the concentrations of OPEs in both seawater and sediments in the YRE were higher in spring than in summer.

Measurements of gas mixture adsorption equilibria at high pressures are important for assessing actual adsorbent selectivities but are often out of reach, given the challenging nature of the required experiments. Here, we report a high-pressure gravimetric binary gas adsorption equilibrium measurement system based on simultaneous gas density and mixture adsorption measurements in a single gas cell coupled to a magnetic-suspension balance. Compared to traditional techniques which rely on analytical measurements of gas composition, this approach does not require any sampling.

Understanding the behaviour of short-chain hydrocarbons confined to porous solids informs the targeted extraction of natural resources from geological features, and underpins rational developments in separation, storage and catalytic conversion processes. Herein, we report the application of low-field (12.7 MHz) H nuclear magnetic resonance (NMR) relaxation measurements to characterise ethane dynamics within mesoporous silica materials exhibiting mean pore diameters between 6 and 50 nm.

A large number of people suffer from life-threatening cardiac abnormalities, and electrocardiogram (ECG) analysis is beneficial to determining whether an individual is at risk of such abnormalities. Automatic ECG classification methods, especially the deep learning based ones, have been proposed to detect cardiac abnormalities using ECG records, showing good potential to improve clinical diagnosis and help early prevention of cardiovascular diseases. However, the predictions of the known neural networks still do not satisfactorily meet the needs of clinicians, and this phenomenon suggests that some information used in clinical diagnosis may not be well captured and utilized by these methods.

"Breathing" and "gating" are striking phenomena exhibited by flexible metal-organic frameworks (MOFs) in which their pore structures transform upon external stimuli. These effects are often associated with eminent steps and hysteresis in sorption isotherms. Despite significant mechanistic studies, the accurate description of stepped isotherms and hysteresis remains a barrier to the promised applications of flexible MOFs in molecular sieving, storage and sensing.

Stepped adsorption isotherms with desorption hysteresis were measured for nitrogen, argon, ethane, carbon dioxide, and methane at pressures up to 17 MPa on zeolitic imidazolate framework-7 (ZIF-7) using a gravimetric sorption analyzer. Such stepped sorption isotherms have not been previously reported for nitrogen or argon on ZIF-7, and required the application of pressures as high as 15 MPa to trigger the ZIF-7 structural phase transition at temperatures around 360 K. The stepped hysteretic sorption isotherms measured for carbon dioxide, methane, and ethane were consistent with previous observations reported in the literature.

A commercial gravimetric sorption analyzer, which is based on a magnetic-suspension balance, was significantly improved to reduce the uncertainty in adsorption measurements. In a previous paper, we investigated the force-transmission error (FTE) of the instrument's magnetic-suspension coupling, and we analysed the uncertainty of the density measurement. In the present paper, equations for the determination of the adsorption on porous and quasi non-porous materials are provided, where the FTE is taken into account, and a detailed uncertainty analysis is presented.

While caesarean section (CS) can be a lifesaving intervention when performed in a timely manner to overcome dystocia or other complications, it is a traumatic event and may increase the risk of post-traumatic stress disorder (PTSD). No attempt has been made to assess prevalence of PTSD after CS specifically. This study aimed to quantify pooled prevalence of PTSD after CS through a systematic review and meta-analysis.
