The effect of periapical bone defects on stress distribution in teeth with periapical periodontitis: a finite element analysis.

Background: Apical periodontitis directly affects the stress state of the affected tooth owing to the destruction of the periapical bone. Understanding the mechanical of periapical bone defects/tooth is clinically meaningful. In this study, we evaluate the effect of periapical bone defects on the stress distribution in teeth with periapical periodontitis using finite element analysis.

The effect of root canal treatment and post-crown restorations on stress distribution in teeth with periapical periodontitis: a finite element analysis.

Aim: To evaluate the effects of root canal treatment (RCT) and post-crown restoration on stress distribution in teeth with periapical bone defects using finite element analysis.

Methodology: Finite element models of mandibular second premolars and those with periapical bone defects (spherical defects with diameters of 5, 10, 15, and 20 mm) were created using digital model design software. The corresponding RCT and post-crown restoration models were constructed based on the different sizes of periapical bone defect models.

Radiation-Induced De Novo Defects in Metal-Organic Frameworks Boost CO Sorption.

Defects in metal-organic frameworks (MOFs) can significantly change their local microstructures, thus notably leading to an alteration-induced performance in sorption or catalysis. However, achieving de novo defect engineering in MOFs under ambient conditions without the scarification of their crystallinity remains a challenge. Herein, we successfully synthesize defective ZIF-7 through Co gamma ray radiation under ambient conditions.

Highly efficient reduction of ammonia emissions from livestock waste by the synergy of novel manure acidification and inhibition of ureolytic bacteria.

The global livestock system is one of the largest sources of ammonia emissions and there is an urgent need for ammonia mitigation. Here, we designed and constructed a novel strategy to abate ammonia emissions via livestock manure acidification based on a synthetic lactic acid bacteria community (LAB SynCom). The LAB SynCom possessed a wide carbon source spectrum and pH profile, high adaptability to the manure environment, and a high capability of generating lactic acid.

Recent Progress toward Physical Stimuli-Responsive Emulsions.

Emulsion as a fine dispersion of immiscible liquids has involved widespread applications in industry, pharmaceuticals, agriculture, and personal care. Stimuli-responsive emulsions capable of on-demand demulsification or changing their properties are required in many cases such as controllable release cargo, oil recovery, emulsifier recycling, and product separation, great progress is achieved in these areas. Among these various triggers, much effort is made to develop physical stimuli, due to the noninvasive and environmentally friendly characteristics.

[Rapid screening of 84 pesticide residues in dendrobium by Sin-QuEChERS Nano purification column with gas chromatography-tandem mass spectrometry].

A rapid screening method for 84 pesticide residues in dendrobium perfringens parent material with different polarities was developed using a Sin-QuEChERS Nano clean-up column combined with gas chromatography-tandem mass spectrometry (GC-MS/MS). The differences in extraction efficiency of the targets were compared with different extraction solvents (acetonitrile containing 1% acetic acid, acetone) and methods (immersion with or without water). The purification effect and extraction recoveries of Sin-QuEChERS Nano method and classical dispersive solid-phase extraction (dSPE), solid-phase extraction (SPE) and QuEChERS were systematically compared using samples.

Methods: We consecutively enrolled 110 patients with uHCC in this prospective cohort study, with 56 patients receiving combination treatment and 54 patients receiving TACE from November 2017 to September 2020. The differences in tumor response, survival benefit, and adverse events (AEs) were compared between the two groups.

Enhancing Thermoelectric Performance of AgSbTe-Based Compounds Microstructure Modulation Combining with Entropy Engineering.

Modulation of the microstructure and configurational entropy tuning are the core stratagem for improving thermoelectric performance. However, the correlation of evolution among the preparation methods, chemical composition, structural defects, configurational entropy, and thermoelectric properties is still unclear. Herein, two series of AgSbTe-based compounds were synthesized by an equilibrium melting-slow-cooling method and a nonequilibrium melting-quenching-spark plasma sintering (SPS) method, respectively.

Removing the Oxygen-Induced Donor-like Effect for High Thermoelectric Performance in n-Type BiTe-Based Compounds.

Bismuth telluride-based alloys are the best performing thermoelectric materials near room temperature. Grain size refinement and nanostructuring are the core stratagems for improving thermoelectric and mechanical properties. However, the donor-like effect induced by grain size refinement strongly restricts the thermoelectric properties especially in the vicinity of room temperature.

North Atlantic Oscillation in winter is largely insensitive to autumn Barents-Kara sea ice variability.

Arctic sea ice extent in autumn is significantly correlated with the winter North Atlantic Oscillation (NAO) in the satellite era. However, questions about the robustness and reproducibility of the relationship persist. Here, we show that climate models are able to simulate periods of strong ice-NAO correlation, albeit rarely.

Boosting Thermoelectric Properties of AgBi(SeS) Solid Solution via Entropy Engineering.

AgBiS is an environmentally friendly n-type thermoelectric material composed of earth-abundant and nontoxic elements. It has a complex monoclinic structure with distorted NaCl-type fragments, which provide its intrinsically low thermal conductivity. However, poor electrical properties limit its overall performance.

Anisotropy of Charge Transport in a Uniaxially Aligned Fused Electron-Deficient Polymer Processed by Solution Shear Coating.

Precise control of the microstructure in organic semiconductors (OSCs) is essential for developing high-performance organic electronic devices. Here, a comprehensive charge transport characterization of two recently reported rigid-rod conjugated polymers that do not contain single bonds in the main chain is reported. It is demonstrated that the molecular design of the polymer makes it possible to achieve an extended linear backbone structure, which can be directly visualized by high-resolution scanning tunneling microscopy (STM).

[Research progress in the heatstroke-induced myocardial injury].

Heat stroke is the most serious type of heat-related diseases, and the induced multiple organ dysfunction syndrome (MODS) is an important cause of death for heat stroke patients. The cardiovascular system is one of the important targets of heat injury. Studies have reported that heat stress can lead to myocardial inhibition, abnormal heart conduction and blood flow redistribution, thus changing the hemodynamic state, leading to obvious abnormalities in electrocardiogram, echocardiography, myocardial injury biological markers and hemodynamic indicators of patients with heat stroke.

[Advances in pre-hospital recognition and cooling treatment of exertional heat stroke].

Heat stroke (HS) is a life-threatening illness characterized by an altered level of consciousness with an elevated core body temperature 40 centigrade, which may be further classified as exertional heat stroke (EHS) or classical heat stroke (CHS) according to the etiology of the condition. In recent years, the morbidity of EHS increases year by year. The severity and clinical outcome for an EHS casualty have a strong correlation with the area under the time and temperature curve for heat exposure.

The Simulation of Stratospheric Water Vapor over the Asian Summer Monsoon Region in CESM1(WACCM) Models.

Previous observational studies have found a persistent maximum in stratospheric water vapor (SWV) in the upper troposphere lower stratosphere (UTLS) confined by the upper-level anticyclone over the Asian summer monsoon region. This study investigates the simulation of SWV in the Whole Atmosphere Community Climate Model (WACCM). WACCM generally tends to simulate a SWV maximum over the central Pacific Ocean, but this bias is largely improved in the high vertical resolution version.

A stratospheric pathway linking a colder Siberia to Barents-Kara Sea sea ice loss.

Previous studies have extensively investigated the impact of Arctic sea ice anomalies on the midlatitude circulation and associated surface climate in winter. However, there is an ongoing scientific debate regarding whether and how sea ice retreat results in the observed cold anomaly over the adjacent continents. We present a robust "cold Siberia" pattern in the winter following sea ice loss over the Barents-Kara seas in late autumn in an advanced atmospheric general circulation model, with a well-resolved stratosphere.

Highly selective recognition of Al and I ions using a bi-functional fluorescent probe.

A tripodal fluorescent probe L1 armed with Rhodamine B and 1-naphthaleneisothiocyanates was prepared in high yield. A study of the recognition properties revealed that probe L1 exhibited high sensitivity and selectivity towards Al through a "FRET" fluorescence response and colorimetric response with low detection limits of the order of 10 M. Meanwhile, probe L1 also possessed high recognition ability for I through fluorescence decay, which given there are comparatively few selective fluorescent probes for I, is significant.

Sodium desoxycholate-assisted capillary electrochromatography with methacrylate ester-based monolithic column on fast separation and determination of coumarin analogs in Angelica dahurica extract.

A rapid and sensitive CEC method with methacrylate ester-based monolithic column has been developed for separation and determination of five coumarins (byakangelicin, oxypeucedanin hydrate, xanthotoxol, 5-hydroxy-8-methoxypsoralen and bergapten) in Angelica dahurica extract. Surfactant sodium desoxycholate (SDC) was introduced into the mobile phase as the pseudostationary to dynamically increase the selectivity of analytes instead of increasing the hydrophobicity of stationary phase. In addition, other factors, pH of phosphate buffer, ACN content and applied voltage, for instance, have also an obvious effect on the resolution but little on the retention time.

Comprehensive two-dimensional high performance liquid chromatography system with immobilized liposome chromatography column and monolithic column for separation of the traditional Chinese medicine Schisandra chinensis.

A comprehensive two-dimensional (2D) separation is one that employs two separation dimensions (columns) and draws on all of the available resolving power from each of the dimensions of separate the components in a sample. In this study, a comprehensive 2D chromatography approach was developed for the separation and identification of membrane permeable compounds in a famous traditional Chinese medicine of Schisandra chinensis. The first dimensional column was the immobilized liposome chromatography (ILC) column, which mimics the biological membranes and can be used to study drug-membrane interactions in liquid chromatography.

Determination of porcine fibrinogen in rat and dog plasma after intraperitoneal injection of a porcine-derived fibrin glue by fluorescein-labeled assay method: Comparison with isotope-labeled assay method.

A sensitive and specific fluorescein isothiocyanate (FITC) label coupled with size-exclusion high-performance liquid chromatography-fluorescence detection (SE-HPLC-FLD) method was developed and validated for the estimation of the pharmacokinetic profiles of porcine fibrinogen after intraperitoneal injection of a porcine-derived fibrin glue (FG) to SD rats and beagle dogs with three single doses. Porcine fibrinogen, the major composition of the FG, was labeled with FITC. The FG containing FITC-labeled porcine fibrinogen was intraperitoneally administered to SD rats at three single dosages (100, 200, 400mg/kg of porcine fibrinogen), and the collected plasma was then detected by SE-HPLC-FLD method.
