Cell proliferation, cell death and angiogenesis in early and advanced gastric cancer of intestinal type.

C Vindigni et al.

International journal of cancer, 74(6), 637-641 (1998-01-08)

Mitotic (MI) and apoptotic index (AI), the sum of the 2, i.e., the turnover index (TI), tumor neovascularization (NV) and p53 expression, as well as tumor grading and node status, are evaluated in early and advanced gastric-cancer cases. T1 cases

Electrochemical behavior of Azure A/gold nanoclusters modified electrode and its application as non-enzymatic hydrogen peroxide sensor.

C Priya et al.

Colloids and surfaces. B, Biointerfaces, 97, 90-96 (2012-05-23)

A novel non-enzymatic hydrogen peroxide sensor was developed using Azure A/gold nanoclusters modified graphite electrode. The method of preparation of Azure A/gold nanoclusters was simple and it was characterized by UV-visible spectroscopy, field emission scanning electron microscopy (FESEM) and confocal

Melanin synthesis by Sclerotinia sclerotiorum.

Michael J Butler et al.

Mycologia, 101(3), 296-304 (2009-06-20)

We confirmed that the melanin produced by Sclerotinia sclerotiorum is a dihydroxynaphthalene (DHN). The specific DHN melanogenesis inhibitor test that uses tricyclazole at low levels (typically 2-5 ppm) to cause a confirmatory appearance of soluble red-brown inhibition products does not

Targeting glucose oxidase at aspartate and glutamate residues with organic two-electron redox mediators.

F Battaglini et al.

Bioconjugate chemistry, 5(5), 430-435 (1994-09-01)

The bimolecular rate constants for the reactions of five organic two-electron redox mediators with reduced glucose oxidase (GOx) were determined by measuring voltammetric electrocatalytic currents at glassy carbon electrodes in the presence of excess glucose under anaerobic conditions. The mediators

A rapid and simple staining method, using toluidine blue, for analysing mitotic figures in tissue sections.

P Chieco et al.

The Histochemical journal, 25(8), 569-577 (1993-08-01)

Mitotic index is a clinically important parameter in cancer pathology. We developed a staining method using Toluidine Blue to detect efficiently and rapidly mitotic figures in sections of formalin-fixed paraffin-embedded human and rat tissues. Sections were stained at acid pH
