Primary solitary fibrous tumor of the stomach: A case report and a review of literature.

Rationale: Solitary fibrous tumors (SFTs) are spindle cell tumors that typically occur in the pleura and peritoneum, but very rarely in the stomach. To our best knowledge, there are only 10 cases reported in English literature. We reported a case of primary stomach SFT and summarized the characteristics of all previous cases, suggesting that pathologists and surgeons should include this disease in the differential diagnosis list of primary mesenchymal tumor of the stomach.

Pharmacokinetic Study of Enteric-Coated Sustained-Release Aspirin Tablets in Healthy Chinese Participants.

Purpose: To study and compare the pharmacokinetic characteristics of enteric-coated sustained-release (EcSr) aspirin tablets with enteric-coated (Ec) aspirin tablets (Bayer S.p.A) in healthy Chinese participants.

Intra-tumoral angiogenesis correlates with immune features and prognosis in glioma.

Gliomas are the most common malignant tumor in the brain. As with other tumors, the progression of glioma depends on intra-tumoral angiogenesis. However, the effect of angiogenesis on gliomas is still not fully understood.

miR-181d promotes pancreatic beta cell dysfunction by targeting IRS2 in gestational diabetes mellitus.

Objectives: Hyperglycemia that develops during pregnancy is a diagnostic criterion of gestational diabetes mellitus (GDM). Current studies have shown that the expression of miRNA-181d is significantly enhanced in the glomeruli of type 2 diabetic. However, the relationship between miR-181d and GDM has never been reported before.

Cisplatin plus paclitaxel chemotherapy with or without bevacizumab in postmenopausal women with previously untreated advanced cervical cancer: a retrospective study.

Background: The aim of this study was to assess the survival outcomes of cisplatin-paclitaxel chemotherapy plus bevacizumab (CPB) versus cisplatin-paclitaxel chemotherapy alone (CPA) in postmenopausal women with previously untreated advanced cervical cancer (CC).

Methods: Consecutive postmenopausal women who experienced CPB or CPA were identified retrospectively from our medical centre during 2015-2019. Follow-up visits occurred 1 and 3 months after starting CPB or CPA.

Expression and diagnostic value of circulating miRNA-190 and miRNA-197 in patients with pulmonary thromboembolism.

Background: Diagnosing pulmonary thromboembolism (PTE) remains challenging due to the lack of specific clinical symptoms and biomarkers. Circulating microRNAs (miRNAs) have proved to be potential biomarkers for numerous cardiovascular diseases. The aims of this study were to quantitatively analyze the expression of plasma miRNA-190 and miRNA-197 in patients with PTE and to evaluate the diagnostic value for PTE.

Mitotic Spindle Apparatus Abnormalities in Chronic Obstructive Pulmonary Disease Cells: A Potential Pathway to Lung Cancer.

Chronic obstructive pulmonary disease (COPD) is a long-term lung disease characterized by irreversible lung damage resulting in airflow limitation, abnormal permanent air-space enlargement, and emphysema. Cigarette smoking is the major cause of COPD with 15% to 30% of smokers developing either disease. About 50% to 80% of patients with lung cancer have preexisting COPD and smokers who have COPD are at an increased risk for developing lung cancer.

The circular RNA NT5E promotes non-small cell lung cancer cell growth via sponging microRNA-134.

The current study tested expression and potential function of circular RNA ecto-5'-nucleotidase (circNT5E) in human non-small cell lung cancer (NSCLC). We show that circNT5E levels are significantly elevated in human NSCLC tissues and cells, correlating with downregulation of its potential targets, miR-134, miR-422a and miR-338. In A549 and primary NSCLC cells, circNT5E shRNA inhibited cancer cell growth, proliferation and migration, whiling inducing apoptosis activation.

MicroRNA-4651 targets bromodomain-containing protein 4 to inhibit non-small cell lung cancer cell progression.

Bromodomain-containing protein 4 (BRD4) overexpression in non-small cell lung cancer (NSCLC) promotes cancer progression. Here, we show that miR-4651 selectively targets and negatively regulates BRD4 in A549 and primary human NSCLC cells. RNA pull-down experiments confirmed that miR-4651 directly binds to BRD4 mRNA.

PbBO: A Polar Lead Oxyborate with Uncommon (BO) Layers Exhibiting a Large Second Harmonic Generation Response.

A new lead oxyborate, PbBO, has been successfully synthesized by introducing stereochemically active Pb cations and distorted OPb tetrahedra into asymmetric borates. PbBO exhibits an unprecedented two-dimensional (BO) layer structure with a large second harmonic generation (SHG) response that is 3 times that of KHPO. In addition, theoretical work, including dipole moment calculations, electronic structure, and SHG coefficients combined with SHG density analysis, is reported.

Structural insights for the design of new borate-phosphates: synthesis, crystal structure and optical properties of Pb₄O(BO₃)(PO₄) and Bi₄O₃(BO₃)(PO₄).

Two new metal borate-phosphates, Pb4O(BO3)(PO4) (1) and Bi4O3(BO3)(PO4) (2), have been successfully designed and synthesized. The structures of the title compounds were determined by single-crystal X-ray diffraction. The title compounds have similar crystal structures consisting of oxygen-centered (OPb4) or (OBi4) tetrahedra as well as isolated BO3 and PO4 groups.

Special ∞¹[OPb2] chains and ∞¹[O2Pb3] ribbons based on OPb4 anion-centered tetrahedra in Pb2(O4Pb8)(BO3)3Br3 and Pb2(O8Pb12)(BO3)2Br6.

The structures of two new lead-containing oxyborate bromines, Pb2(O4Pb8)(BO3)3Br3 (1) and Pb2(O8Pb12)(BO3)2Br6 (2), are determined by single-crystal X-ray diffraction for the first time. Both of them crystallize in the space group C2/c of the monoclinic crystal system. Although the two compounds have the same type of fundmental building units (FBUs), the OPb4 anion-centered tetrahedra and BO3 triangles, they exhibit different connection modes.

New molybdenum(VI) phosphates: synthesis, characterization, and calculations of centrosymmetric RbMoO2PO4 and noncentrosymmetric Rb4Mo5P2O22.

Two new molybdenum(VI) phosphates, RbMoO(2)PO(4) and Rb(4)Mo(5)P(2)O(22), have been synthesized by standard solid-state reactions, and their structures were determined by single-crystal X-ray diffraction. The former is centrosymmetric, whereas the latter is noncentrosymmetric and chiral. Their crystal structures both consist of corner- and edge-shared MoO(6) octahedra, PO(4) tetrahedra, and RbO(n) (n = 8 or 10) polyhedra and exhibit three- and one-dimensional structures, respectively.
