Objective: To investigate the diagnostic performance of microRNA-21 detected in serum or sputum as a biomarker for lung carcinoma identification through pooling the open published data.
Methods: Clinical diagnostic studies related to microRNA-21 as a biomarker for lung carcinoma identification were electronically searched in the databases of Pubmed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, and Google Scholar. The data of the included studies was extracted and made pooling of diagnostic sensitivity, specificity, diagnostic odds ratio (DOR), area under the summary receiver operating characteristic curve (ROC) (AUC) for microRNA-21 expression in serum or sputum as a biomarker for lung carcinoma identification.
The approval of immune checkpoint inhibitors has expanded treatment options for renal cell carcinoma (RCC), but new therapies that target RCC stemness and promote anti-tumor immunity are needed. Previous findings demonstrate that doublecortin-like kinase 1 (DCLK1) regulates stemness and is associated with RCC disease progression. Herein, we demonstrate that small-molecule kinase inhibitor DCLK1-IN-1 strongly inhibits DCLK1 phosphorylation and downregulates pluripotency factors and cancer stem cell (CSC) or epithelial-mesenchymal transition (EMT)-associated markers including c-MET, c-MYC, and N-Cadherin in RCC cell lines.

Tumor suppressor p53 and chemokine receptor CXCR4 were both implicated in the AKI pathology. Here, we report on the development and evaluation of polymeric CXCR4 antagonist (PCX) siRNA carrier for selective delivery to injured kidneys in AKI.

Kinetics and isotherm models indicated that the removal process of uranium on AlO-SiO-T accorded with pseudo-second-order kinetic model and Langmuir isotherm model, which showed that the adsorption process was a uniform mono-layer chemical behavior. The maximum adsorption capacity of AlO-SiO-T reached 738.

In this work, firstly, surface charge property of the PHN was evaluated by ζ-potential and retention of NO. A considerable amount of pH-dependent positive charges was confirmed more than that on CSH Phenyl-Hexyl, a commercial positively-charged phenyl stationary phase.

Aims: To develop a nomogram to predict 30-day readmission in patients with AP and validate the usefulness of serum indicators after discharge for the prediction of 30-day readmission.
Methods: This was a retrospective cohort study enrolling patients with the first attack of AP.
Pancreatic ductal adenocarcinoma is a deadly disease with limited treatment options due to late diagnosis and resistance to conventional chemotherapy. Among emerging therapeutic targets, the CXCR4 chemokine receptor and polo-like kinase 1 (PLK1) play critical roles in the progression, metastasis, and chemoresistance of pancreatic cancer. Here, we tested the hypothesis that combining CXCR4 inhibition by a polymeric CXCR4 antagonist PAMD-CHOL with PLK1 knockdown by siRNA will enhance the therapeutic effect of gemcitabine (GEM) in the orthotopic model of metastatic pancreatic cancer.

This study aimed to investigate the adhesive performance of printed polyetheretherketone (PEEK) after acid etching to veneering resin. In total, 182 PEEK specimens (including 91 printed and 91 milled specimens) were distributed to 14 subgroups ( = 13/subgroup), according to the manufacturing process and surface treatment.

An efficacious vaccine for children and adolescents could therefore assist pandemic control. For further evaluation of the inactivated COVID-19 vaccine candidate BBIBP-CorV, we assessed the safety and immunogenicity of BBIBP-CorV in participants aged 3-17 years.

In this work, the photodegradation of MPs mediated by five different types of soils were investigated. The results showed: after 20 d of xenon lamp irradiation, significant degradation of MP was observed on Harbin (S1), Huainan (S2), Jiangxi (S3), Shaanxi (S4) and Hainan (S5).

Strong absorption and large bandwidth are two contributors to materials' absorbing performance. In this work, a series of multi-element core-shell magnetic nano-particle composite layered graphene absorbing materials CoFeO@C/rGO (CCr) were prepared by adjusting carbon shell thickness. The CCr at a low thickness achieved strong microwave absorption and a wide effective absorption bandwidth.

In the present study, targeted and untargeted mass spectrometry-based metabolomics was applied to elucidate the transfer of bioactive compounds between rye and several crops and weed species. Our results demonstrated that benzoxazinoids (BXs) synthesized by rye were taken up by roots of neighbouring plant species and translocated into their shoots.

Potentilla anserina L polysaccharide (PAP) holds promising physiological and pharmacological properties which could be beneficial for HAPE treatment. In our study, the anti-hypoxia effect of PAP was firstly investigated through anti-normobaric hypoxia test and anti-acute hypoxia test.

However, the current 3D printed PEEK (brown color) cannot mimic the vivid color of oral tissues and thus cannot meet the esthetical need for dental application. Therefore, titanium dioxide (TiO) and ferric oxide (FeO) were incorporated into PEEK to prepare a series of tooth-color and gingival-color PEEK composites in this study.

Diffusion tensor imaging technology can provide information on the white matter of the brain, which can be used to explore changes in brain tissue structure, but it lacks the specific description of the microstructure information of brain tissue. The neurite orientation dispersion and density imaging make up for its shortcomings. But in order to accurately estimate the brain microstructure, a large number of diffusion gradients are needed, and the calculation is complex and time-consuming through maximum likelihood fitting.
