Detection of egg white allergy in children by specific IgE microarray chemiluminescence immunoassay.

Background: Allergen testing has emerged as a pivotal component in prevention and treatment strategies for allergic diseases among children and the utilization of specific IgE (sIgE) through a fully automated chemiluminescent microarray immunoassay (CLMIA) has emerged as a promising trend in the simultaneous detection of multiple allergenic components of children.

Methods: The accuracy and reliability of CLMIA were verified using children's serum samples that concentrated on allergens. the allergens.

Astragaloside IV improves the pharmacokinetics of febuxostat in rats with hyperuricemic nephropathy by regulating urea metabolism in gut microbiota.

Hyperuricemic nephropathy (HN) is a common clinical complication of hyperuricemia. The pathogenesis of HN is directly related to urea metabolism in the gut microbiota. Febuxostat, a potent xanthine oxidase inhibitor, is the first-line drug used for the treatment of hyperuricemia.

Electrochemical preparation and properties of a Mg-Li-Y alloy co-reduction of Mg(ii) and Y(iii) in chloride melts.

Mg-Li based alloys have been widely used in various fields. However, the widespread use of Mg-Li based alloys were restricted by their poor properties. The addition of rare earth element in Mg-Li can significantly improve the properties of alloys.

Circular RNA hsa_circ_0000730 restrains cell proliferation, migration, and invasion in cervical cancer through miR-942-5p/PTEN axis.

Circular RNAs (circRNAs) play prominent roles in regulating the progression of cancers. This study is aimed to decipher the role of hsa_circ_0000730 in cervical cancer (CC).The differentially expressed circRNAs of CC were screened out from the Gene Expression Omnibus database.

Two birds with one stone: a NIR fluorescent probe for mitochondrial protein imaging and its application in photodynamic therapy.

Mitochondrial proteins, most of which are encoded in the nucleus and the rest of which are regulated by the mitochondrial genome, play pivotal roles in essential cellular functions. However, fluorescent probes that can be used for monitoring mitochondrial proteins have not yet been widely developed, thereby severely limiting the exploration of the functions of proteins in mitochondria. Towards this end, here we propose a near-infrared (NIR) fluorescence probe MPP to effectively illuminate the dynamic changes in mitochondrial proteins in live cells under oxidative stress, with excellent temporal and spatial resolution.

Pharmacophore-inspired discovery of FLT3 inhibitor from kimchi.

Globally consumed kimchi is manufactured through fermenting cruciferous vegetables containing indole glucosinolates (IG). But few reports describe the IG metabolism during the fermentation. Here, we show that indole-3-carbinol (I3C), a breakdown product of IG, is transformed during the kimchi fermentation into 3,3'-diindolylmethane (DIM) and 2-(indol-3-ylmethyl)-3,3'-diindolylmethane (LTr1).

DNA nanopore functionalized with aptamer and cell-penetrating peptide for tumor cell recognition.

In the present work, DNA nanopore was composed of a bundle of six DNA duplexes folded from six DNA strands and functionalized with Ramos cell aptamer and cell-penetrating peptide (CPP). Herein, we present a unique dually conjugated molecule with an aptamer and cell-penetrating peptide for targeting and recognition of Ramos cells. The aptamer sequence was specific bound to Ramos cell, at the meanwhile the nanopore assembly was taken onto the surface of cell membrane and then got into the cells with the help of CPP.

Targeted therapy for gastric cancer: Current status and future directions (Review).

According to the 2012 statistics of the International Agency for Research on Cancer (IARC), gastric cancer is the fifth most common malignancy, and the third leading cause of cancer-related deaths worldwide. Conventional chemotherapy and radiation have shown limited efficacy for advanced gastric cancer, showing an overall survival (OS) rate of ~10 months. Trastuzumab, a monoclonal antibody against human epidermal growth factor receptor 2 (HER2), is the first approved molecularly targeted agent for HER2-overexpressing gastric cancer, which was found to prolong the OS and the progression-free survival (PFS) of patients.

A Quinoline-Based Ratiometric and Reversible Fluorescent Probe for Cadmium Imaging in Living Cells.

We report a novel ratiometric and reversible fluorescent probe for Cd(2+) detection utilizing a 6-(dimethylamino)quinaldine derivative as the fluorophore and a 2-hydrazinopyridine derivative as Cd(2+) chelator. This ratiometric fluorescent probe possesses favorable photophysical properties. It shows a large (55 nm) red-shift from 515 nm to 570 nm in the emission spectrum.

[The effect of eukaryotic expression plasmid ARHI on gastric cancer].

Objective: To study the effect of expressed aplasia ras homolog member I (ARHI) on the malignant biological behaviors of gastric cancer including the proliferation, migration and invasion of the cell.

Methods: The eukaryotic expression plasmid of ARHI was constructed and transfected into MKN-28 cell with lipofectamine 2000 as pEGFP-ARHI group, transfected with pEGFP-N1 as pEGFP-N1 group, and untreated MKN-28 as control group. The expression of ARHI was detected by Western blotting and fluorescence microscope.

[Human papillomavirus genotype distribution in invasive squamous cell carcinoma of the uterine cervix in Mongolian women in inner Mongolia autonomy region].

Objective: To investigate the prevalence of human papillomavirus (HPV) and the HPV genotype distribution in invasive squamous cell carcinoma of the uterine cervix in the Mongolian women in Inner Mongolia autonomy region.

Methods: The prevalence data of HPV in our department were retrospectively reviewed. INNO-LiPA genotyping technique was used to detect HPV genotypes in the reserved carcinoma tissue specimens.
