Soft material with intense photoluminescence obtained by dissolving Eu2O3 and organic ligand into a task-specific ionic liquid.

A task-specific ionic liquid containing a carboxylate group with the ability to dissolve metal oxide and organic ligands has been used as the solvent to prepare lanthanide complexes without the addition of extra solvent; thus a soft material with intense photoluminescence has been obtained by directly dissolving Eu(2)O(3), 2-thenoyltrifluoroacetone (TTA) and 1,10-phenanthroline (Phen) into the task-specific ionic liquid.

[Roles of endothelin and its receptors in prostate cancer].

Endothelin (ET) is a peptide released by vascular endothelial cells. Except for the potent vasoconstrictor function it plays an important physiological role in tissue differentiation and development, cell proliferation and hormone production. Investigation of the role of ET axis in a variety of tumors such as prostatic, cervical, breast carcinoma has provided evidences of its importance in cancer, recently.

Free graft two-stage urethroplasty for hypospadias repair.

Objective: To evaluate the effectiveness of free graft transplantation two-stage urethroplasty for hypospadias repair.

Methods: Fifty-eight cases with different types of hypospadias including 10 subcoronal, 36 penile shaft, 9 scrotal, and 3 perineal were treated with free full-thickness skin graft or (and) buccal mucosal graft transplantation two-stage urethroplasty. Of 58 cases, 45 were new cases, 13 had history of previous failed surgeries.

Effects of pollen extract EA-10, P5 on chronic prostatitis or infertility with chronic prostatitis.

Aim: To determine the drug action mechanism of pollen extract EA-10, P5 on the treatment of chronic prostatitis (CP) or infertility with CP.

Methods: Malondiadehyde (MDA), superoxide dismutase (SOD), and nitrogen monoxide (NO) were measured by biochemical assay, and zinc content was assayed by atomical spectrophotography in the pre-treatment and post-treatment of CP or infertility with CP.

Results: Compared with control group, leukocytes in expressed protatic secretion (LEPS), MDA, and NO were increased, and zinc content and SOD were decreased significantly in the pre-treatment of CP.

The role of superoxide anion in the regulation of epidermal growth factor or the expression and proliferation of its receptor in prostate cancer cell line PC3.

The purpose of this study was to investigate the role of superoxide anion(O2-) in the regulation of epidermal growth factor (EGF) or epidermal growth factor receptor (EGFR) expression and proliferation in the prostate cancer cell line PC3. Cell proliferation was tested by a 3-(4,5-dimethylthiazol-2-yl)-diphenyltetrazolium bromide (MTT) assay in the presence of O2-, EGF or their combination. Immunohistochemistry was carried out to assay the expression of EGF or EGFR.
