The N,N,N',N'-tetraphenylbenzidine-based conjugated hypercrosslinked polymers for adsorping iodine and fluorescence sensing 2,4-dinitrophenol, iodine.

Although progress has been made in the development of hypercrosslinked polymers (HCPs) for iodine uptake, their fluorescence performance and fluorescence sensing performance are rare due to the lack of conjugated behavior in common HCPs. Herein, the N,N,N',N'-tetraphenylbenzidine-based conjugated hyper-crosslinked polymers (conjugated TPB-based HCPs) were efficiently fabricated via a one-step Friedel-Crafts arylation reaction by selecting N,N,N',N'-tetraphenylbenzidine (TPB) and N,N'-diphenyl-N,N'-di(m-tolyl)benzidine (DPDB) as the basic building blocks and p-dimethoxybenzene (DMB) as an external crosslinker which will lead to the formation of the conjugated structures. The derived TPB-based HCPs (denoted as, TPB-DMB and DPDB-DMB) possessed excellent stability and high surface areas, Their iodine adsorption capacities are up to 4.

Radiomics model based on contrast-enhanced computed tomography to predict early recurrence in patients with hepatocellular carcinoma after radical resection.

Background: Radical resection remains an effective strategy for patients with hepatocellular carcinoma (HCC). Unfortunately, the postoperative early recurrence (recurrence within 2 years) rate is still high.

Aim: To develop a radiomics model based on preoperative contrast-enhanced computed tomography (CECT) to evaluate early recurrence in HCC patients with a single tumour.

Novel index for the prediction of significant liver fibrosis and cirrhosis in chronic hepatitis B patients in China.

Background: Noninvasive, practical, and convenient means of detection for the prediction of liver fibrosis and cirrhosis in China are greatly needed.

Aim: To develop a precise noninvasive test to stage liver fibrosis and cirrhosis.

Methods: With liver biopsy as the gold standard, we established a new index, [alkaline phosphatase (U/L) + gamma-glutamyl transpeptidase (U/L)/platelet (10/L) (AGPR)], to predict liver fibrosis and cirrhosis.

Four new species within the genus , , , , and , are proposed based on a combination of morphological traits, physiological features, and molecular evidences. is characterized by globose sporangiospores, a 1.0- to 3.

Transcriptome Reveals Roles of Lignin-Modifying Enzymes and Abscisic Acid in the Symbiosis of and .

is a well-known medicinal and heterotrophic orchid. Its germination, limited by the impermeability of seed coat lignin and inhibition by abscisic acid (ABA), is triggered by symbiosis with fungi such as spp. However, the molecular mechanisms of lignin degradation by and ABA biosynthesis and signaling in remain unclear.

Two New Species in the Family Cunninghamellaceae from China.

The species within the family Cunninghamellaceae are widely distributed and produce important metabolites. Morphological studies along with a molecular phylogeny based on the internal transcribed spacer (ITS) and large subunit (LSU) of ribosomal DNA revealed two new species in this family from soils in China, that is, sp. nov.

[Efficacy of Oxycodone Hydrochloride for Patient-controlled Intravenous Analgesia after General Surgery].

To evaluate the value of oxycodone hydrochloride for postoperative pain management in patients undergoing patient-controlled intravenous analgesia(PCIA). The medical records on postoperative pain management in our department from January 1 to June 30,2018,were retrospectively analyzed.Totally 136 patients were assigned into oxycodone,sufentanil,or morphine groups according to the opioid used in the PCIA.

Adsorption mechanism of extracellular polymeric substances from two bacteria on Ultisol and Alfisol.

The primary objective of this study was to identify the capacity and mechanism of extracellular polymeric substance (EPS) adsorption on soil colloids of Alfisol and Ultisol at different pH and ionic strengths. Two kinds of EPS were extracted from Bacillus subtilis and Pseudomonas fluorescens by centrifugation, and their adsorption on Ultisol and Alfisol was investigated using a batch adsorption experiment and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR). The average diameter of EPS from B.

The primary objective of this study was to determine the capacity and the mechanisms of adhesion of Bacillus subtilis onto variable- and constant-charge soil colloids. The adhesion process was investigated using in situ attenuated total reflectance (ATR)-Fourier transform infrared spectroscopy (FTIR), zeta potential, and batch adhesion experiments. The maximum adhesion capacity of B.

[Effect of ulinastatin on liver function of patients after bilateral total knee arthroplasty].

Objective: To investigate the effect of ulinastatin, a urinary trypsin inhibitor, on the postoperative liver function in patients who have received bilateral total knee arthroplasty (TKA) under pneumatic tourniquet.

Methods: Totally 40 patients who were scheduled to receive bilateral TKA under thigh tourniquet were randomly assigned into trial group (U group, receiving intravenous ulinastatin) and control group (C group, receiving natural saline). All patients received the same general anesthesia and postoperative analgesia.

Methods: Totally 32 adult patients scheduled for elective total knee arthroplasty were equally randomized into CFNB group or PCIA group. Intraoperative hemodynamics and fentanyl dose were recorded.

Region- or state-related differences in expression and activation of extracellular signal-regulated kinases (ERKs) in naïve and pain-experiencing rats.

Background: Extracellular signal-regulated kinase (ERK), one member of the mitogen-activated protein kinase (MAPK) family, has been suggested to regulate a diverse array of cellular functions, including cell growth, differentiation, survival, as well as neuronal plasticity. Recent evidence indicates a role for ERKs in nociceptive processing in both dorsal root ganglion and spinal cord. However, little literature has been reported to examine the differential distribution and activation of ERK isoforms, ERK1 and ERK2, at different levels of pain-related pathways under both normal and pain states.

Peripheral iron dextran induced degeneration of dopaminergic neurons in rat substantia nigra.

Iron accumulation is considered to be involved in the pathogenesis of Parkinson's disease. To demonstrate the relationship between peripheral iron overload and dopaminergic neuron loss in rat substantia nigra (SN), in the present study we used fast cyclic voltammetry, tyrosine hydroxylase (TH) immunohistochemistry, Perls' iron staining, and high performance liquid chromatography-electrochemical detection to study the degeneration of dopaminergic neurons and increased iron content in the SN of iron dextran overloaded animals. The findings showed that peripheral iron dextran overload increased the iron staining positive cells and reduced the number of TH-immunoreactive neurons in the SN.
