AIMS The aim of this study was to investigate the role of cyclooxygenase (COX)-1 on vascular alterations in structure, mechanics, and extracellular matrix (ECM) components induced by angiotensin (Ang) II in mesenteric arteries from wild-type (WT) and COX-1 knockout (COX-1(-/-)) mice. METHODS AND RESULTS Animals were infused with vehicle or Ang II (400 ng/kg/min, s.c.) ± SC-560 (COX-1 inhibito...

Objective Sodium fluorescein (FL) had been safely used in fluorescence-guided microsurgery for imaging various brain tumors. Under the YELLOW 560 nm surgical microscope filter, low-dose FL as a fluorescent dye helps in visualization. Our study investigated the safety and efficacy of this innovative technique in malignant glioma (MG) patients. Patients and Method 38 patients suffering from MGs...

BACKGROUND Antinuclear antibodies (ANAs) in women with recurrent miscarriage have been reported. The presence of moderate to high titers of these antibodies represents an autoimmune condition that can endanger the health of the fetus in pregnant women. OBJECTIVE In this study, we evaluated the prevalence of ANAs in Iranian women with a history of two or more unexplained abortion. MATERIALS ...

The present study was designed to investigate the effects of cyclooxygenase (COX) inhibitors in combination with taxol on the expression of cyclin D1 and Ki-67 in human ovarian SKOV-3 carcinoma cells xenograft-bearing mice. The animals were treated with 100 mg/kg celecoxib (a COX-2 selective inhibitor) alone, 3 mg/kg SC-560 (a COX-1 selective inhibitor) alone by gavage twice a day, 20 mg/kg tax...

A radioinhibitor binding assay and an enzyme inhibition assay have been developed to measure plasma levels of CGP 38 560, a potent human renin inhibitor. The detection limit of the assays was between 0.5 and 1 pmol/ml. There was a good correlation (r = 0.989) between the two assays for the measurement of human plasma spiked with CGP 38 560 in concentrations from 1.9 nM to 12 microM. Intra-assay...

DNA-based molecular markers for differentiation of five penaeid shrimps (Penaeus monodon, P. semisulcatus, Feneropenaeus merguiensis, Litopenaeus vannamei and Marsupenaeus japonicus) were developed based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and single-stranded conformation polymorphism (SSCP) of 16S ribosomal (r) DNA. Differentiation of P. monodon, P....

Basalt fibre composite materials have shown good application prospects in electrical equipment, but their reliability can be affected by damp-heat ageing. In this work, the interface, mechanical, and properties of basalt composites treated with three coupling agents via ageing were compared. Molecular simulations conducted to reveal mechanism composites. The results show that γ-aminopropyl trie...
