Malignant epithelioid tumors with EWSR1::CREB fusion involving the kidney: a report of two cases.

Soft tissue tumors with EWSR1/FUS fusion to genes encoding the cyclic adenosine monophosphate response element-binding (CREB) transcription factor family (ATF1, CREB1, and CREM) are rare and heterogeneous aggressive tumors, often found in the peritoneal cavity. Here, we report two cases of malignant epithelioid tumors with EWSR1::CREB fusion involving the kidney in females in their 30 s. Both tumors appeared as solitary masses, measuring 5.

Loss of SATB2 and CDX2 expression is associated with DNA mismatch repair protein deficiency and BRAF mutation in colorectal cancer.

The relationship between the expression of the SATB2 and CDX2 proteins and common molecular changes and clinical prognosis in colorectal cancer (CRC) still needs further clarification. We collected 1180 cases of CRC and explored the association between the expression of SATB2 and CDX2 and clinicopathological characteristics, molecular alterations, and overall survival of CRC using whole-slide immunohistochemistry. Our results showed that negative expression of SATB2 and CDX2 was more common in MMR-protein-deficient CRC than in MMR-protein-proficient CRC (15.

Effects of Co-Culture EBV-miR-BART1-3p on Proliferation and Invasion of Gastric Cancer Cells Based on Exosomes.

Aim: EBV encodes at least 44 miRNAs involved in immune regulation and disease progression. Exosomes can be used as carriers of EBV-miRNA-BART intercellular transmission and affect the biological behavior of cells. We characterized exosomes and established a co-culture experiment of exosomes to explore the mechanism of miR-BART1-3p transmission through the exosome pathway and its influence on tumor cell proliferation and invasion.

Personalized nutrition intervention improves nutritional status and quality of life of colorectal cancer survivors in the community: A randomized controlled trial.

Objectives: This study aimed to evaluate the effects of personalized nutrition intervention combined with telephone-based education on the nutritional status of colorectal cancer survivors and their quality of life.

Methods: In this randomized, parallel-controlled trial, 60 colorectal cancer survivors who met the eligibility criteria were recruited from a community in Shanghai and randomly assigned 1:1 into nutrition intervention and routine care groups. The routine care group received a follow up by telephoneafter 6 months.

Unprecedented Formation of a Binuclear Au(II)-Au(II) Complex through Redox State Cycling: Electrochemical Interconversion of Au(I)-Au(I), Au(II)-Au(II), and Au(I)-Au(III) in Binuclear Complexes Containing the Carbanionic Ligand CFPPh.

The rational design of binuclear Au(I)-Au(I), Au(II)-Au(II), and Au(I)-Au(III) complexes requires an understanding of how the redox states interconvert. Herein, the electrochemical interconversion of the three oxidation states I, II, and III is reported on the voltammetric (cyclic and rotating disk electrode) time scales for binuclear gold complexes containing CFPPh as a ligand, to demonstrate for the first time formation of a binuclear Au(II)-Au(II) from a Au(I)-Au(III) complex. Results are supported by bulk electrolysis and coulometry with reaction products being identified by P NMR and UV-vis spectroscopy.

Application of Bayesian Inference in Fourier-Transformed Alternating Current Voltammetry for Electrode Kinetic Mechanism Distinction.

Estimation of parameters of interest in dynamic electrochemical (voltammetric) studies is usually undertaken via heuristic or data optimization comparison of the experimental results with theory based on a model chosen to mimic the experiment. Typically, only single point parameter values are obtained via either of these strategies without error estimates. In this article, Bayesian inference is introduced to Fourier-transformed alternating current voltammetry (FTACV) data analysis to distinguish electrode kinetic mechanisms (reversible or quasi-reversible, Butler-Volmer or Marcus-Hush models) and quantify the errors.

Molecular cloning, characterization and expression analysis of S- adenosyl- L-homocysteine hydrolase (SAHH) during the pathogenic infection of Litopenaeus vannamei by Vibrio alginolyticus.

SAHH is an enzyme, playing a significant role in the catalyzation of the S-adenosyl homocysteine (SAH) into homocysteine (Hcy) and adenosine (Ado). However, little is known information of the enzyme in crustaceans. In the present study, SAHH cDNA was cloned from Litopenaeus vannamei (LvSAHH).

Unlocking the Electrocatalytic Activity of Antimony for CO Reduction by Two-Dimensional Engineering of the Bulk Material.

Two-dimensional (2D) materials are known to be useful in catalysis. Engineering 3D bulk materials into the 2D form can enhance the exposure of the active edge sites, which are believed to be the origin of the high catalytic activity. Reported herein is the production of 2D "few-layer" antimony (Sb) nanosheets by cathodic exfoliation.

Dual-Frequency Alternating Current Designer Waveform for Reliable Voltammetric Determination of Electrode Kinetics Approaching the Reversible Limit.

Alternating current (ac) voltammetry provides access to faster electrode kinetics than direct current (dc) methods. However, difficulties in ac and other methods arise when the heterogeneous electron-transfer rate constant (k(0)) approaches the reversible limit, because the voltammetric characteristics become insensitive to electrode kinetics. Thus, in this near-reversible regime, even small uncertainties associated with bulk concentration (C), diffusion coefficient (D), electrode area (A), and uncompensated resistance (Ru) can lead to significant systematic error in the determination of k(0).

A wireless and sensitive detection of octachlorostyrene using modified AuNPs as signal-amplifying tags.

A wireless, remote query octachlorostyrene (OCS) biosensor was fabricated by coating a mass-sensitive magnetoelastic ribbon with anti-OCS antibody. In response to a time-varying magnetic field, the magnetoelastic sensor mechanically vibrates at a characteristic resonance frequency which inversely depends on the sensor mass loading. As the magnetoelastic film is magnetostrictive itself, the vibrations launch magnetic flux that can be remotely detected using a pickup coil.

An octachlorostyrene electrochemical immunosensor: double amplification strategies with immobilization of nano-Au and Au nanoparticle labels.

Anti-octachlorostyrene (OCS) antibody was derived from an immune rabbit preparation. An OCS immunosensor was constructed by immobilizing the anti-OCS antibody on a glassy carbon electrode coated with chitosan and gold nanoparticles (AuNPs, ∼5 nm, represented as AuNP05). Large-sized AuNPs (∼90 nm, represented as AuNP90) were used as the electrochemical label.

A photoelectrochemical immunosensor for tris(2,3-dibromopropyl) isocyanurate detection with a multiple hybrid CdTe/Au-TiO2 nanotube arrays.

In this paper, tris(2,3-dibromopropyl) isocyanurate (TBC) is for the first time as far as we know determined by ultrasensitive photoelectrochemical (PEC) immunoassay using an antibody-modified ternary hybrid CdTe/Au-TiO2 nanotube arrays (NTAs) photoelectrode, developed by the pulse electrodeposition technique. The as-prepared hybrid shows enhanced photon absorption and photocurrent response, which subsequently increased the photoelectrical conversion efficiency in the visible region. TBC-antibody (Ab) was developed in rabbits as a result of immunization with the BSA-TBC conjugate and covalently cross-linked onto the CdTe/Au-TiO2 NTAs.

Electrogenerated chemiluminescence detection of trace level pentachlorophenol using carbon quantum dots.

Pentachlorophenol (PCP) is an environmental pollutant of serious concern due to its high toxicity and long persistence property. Fast and sensitive detection of PCP is therefore of great interest. In this work, carbon quantum dots (QDs) are synthesized by hydrothermal reaction, and characterized by fluorescence spectrophotometer, fourier transform infrared (FT-IR) spectroscopy, UV/vis/NIR spectrophotometer and scanning electron microscopy (SEM).

Two types of ATPases from the Pacific white shrimp, Litopenaeus vannamei in response to environmental stress.

V-H ATPase and NaK ATPase are important classes of ATP-driven proton pumps that are present in the intracellular and plasma membranes of eukaryotic cells and play diverse roles in both normal and abnormal cellular processes. Among the subunits of the V-H ATPase complex, subunit a is a transmembrane glycoprotein that plays crucial roles in metabolism, growth, survival and cellular immunity. NaK ATPase subunit beta is thought to participate in the proper folding and movement of the NaK ATPase enzyme and may also aid cation transport.
