In recent years, the occurrence of novel per-/polyfluoroalkyl substances (PFASs) such as polyfluoroalkyl ether sulfonates (PFAESs) in human samples have aroused attention due to change PFASs production profile, however, data are still lacking. Furthermore, epidemiological studies examined associations PFAS exposure with glucose homeostasis, but inconsistent results. Therefore, this study, fasting serum from 252 participants an age range 19 87 years old were collected Tianjin, China. A total...

Organophosphate esters (OPEs) are widely used as flame retardants and plasticizers in consumer industrial products. Human exposure to OPEs raises concerns due their endocrine disruptive potentials. Till now, the effects of on thyroid hormones (THs) mediating role oxidative stress pregnant women have not been studied. In this study, prenatal urinary concentrations OPE metabolites (mOPEs), levels free triiodothyronine (FT3), thyroxine (FT4), thyroid-stimulating hormone (TSH), 8-hydroxy-2-deoxy...

A large-scale survey was conducted by measuring five organophosphite antioxidants (OPAs) and three novel organophosphate esters (NOPEs) in 139 dust samples across China. The median summed concentrations of OPAs NOPEs outdoor were 33.8 ng/g (range: 0.12–53,400 ng/g) 7990 (2390–27,600 ng/g), respectively. associated with the increasing economic development population density from western to eastern China, whereas NOPE concentration Northeast China (median, 11,900 ng/g; range, 4360–16,400...

ObjectiveThe risk factors and the impact of NAI treatments in patients with severe influenza A-associated pneumonia remain unclear.MethodsA multicenter, retrospective, observational study was conducted Zhejiang, China during a epidemic August 2017–May 2018. Clinical records (>14 y) hospitalized laboratory-confirmed A virus infection who developed were compared to those mild-to-moderate pneumonia. Risk related severity effects (monotherapy combination peramivir oseltamivir)...

The human exposome remains limited due to the challenging analytical strategies used reveal low-level endocrine-disrupting chemicals (EDCs) and their metabolites in serum urine. This limits integrity of EDC exposure assessment hinders understanding cumulative health effects. In this study, we propose an enhanced protocol based on multi-solid-phase extraction (multi-SPE) expand with polar EDCs train a machine learning (ML) model for methodology prediction molecular descriptors. measurement 70...

The objective of this study is to explore the effect and mechanism ultrasound on chitin extraction from shrimp shells powder (SSP) by co-fermentation Bacillus subtilis Acetobacter pasteurianus. After pre-treating SSP with high-intensity (HIU) at 800 W, protease activity in fermentation solution reached 96.9 U/mL day 3, which was significantly higher than for that had not been pre-treated (81.8 U/mL). time process 5.0 d without pre-treatment, while it shortened 4.5 when using W treat SSP....

Abstract Objective Interactions between drugs and polymers were utilized to lower the processing temperature of hot-melt extrusion (HME), thus minimize thermal degradation heat-sensitive during preparation amorphous solid dispersions. Methods Diflunisal (DIF), which would degrade upon melting, was selected as a model drug. Hydrogen bonds DIF polymeric carriers (PVP K30, PVP VA64, hydroxypropyl methylcellulose Soluplus) revealed by differential scanning calorimetry Fourier transform infrared...

Endophytic fungi (Fusarium mairei) culture broth (EFCB) was added to cell suspension cultures of Taxus cuspidata. After 5 days, T. cuspidata given 4 ml EFCB produced a maximal yield 6.11 mg/l paclitaxel, with release ratio 75%, 2- and 6.8-fold, respectively, greater than the controls. The active element in is an exopolysaccharide approximately 79 kD. 0.19 paclitaxel its producing medium. However, when supernatant from day 20 paclitaxel-producing medium, biomass decreased by 24% 45%. In...
